What are the vehicle dismantling tools:
1. Awareness and use of manual tools
1. Wrestler class
A manual handling tool for bolting or spiraling bolts, bolts, etc。
(1) an open wrench: the most common type of wrench, also known as a dumb wrench, with a fixed-sized opening at one or both ends, to twist a particular size of a nut or bolt。
(2) plum wrench: the working end with a hexagonal or 12-angle hole at both ends applies to situations where the work space is small and the normal wrench cannot be used. (1) and (2) contrast: the wrench of clubs is of high intensity compared to the opening wrench and is not easy to slip when used, but is not easy to fit and remove。
(3) scrap wrench: it consists of multiple drums with a hexagonal or 12-angular hole with a variety of attachments, such as handles, poles, etc., which are particularly applicable to bolts or screws that are very narrow or dim。
(4) activity wrench: the width of the opening can be adjusted at a certain size and the bolts or nuts of different specifications can be twisted。
(5) twisting wrench: it displays the wrench imposed when it turns the bolt or nut; or it sends a light or sound signal when the wrench imposed reaches the specified value。
(6) a six-point wrench: a six-angled wrench in l form, specially designed for the twisting of a six-angle screw. The specification is expressed in hexagonal to side size。
Snails
A hand-made tool used to tighten or thaw a trough of various sizes with screws, wooden screws and self-attack screws. Also called screwdrivers, caps, cones. The screwrix is usually divided into single fonts, crosses, hexagonals and flower types, with the respective screwdrivers, respectively. Of these, one font and crosses are most commonly used。
Hand hammers, handpliers
Hammer: manual tools used to knock or hammer objects. The hammer consists of both the hammer head and the handle. The use of hammers is widespread and in many forms and specifications. The most common are round hammers, horn hammers, hammers and hammers。
Handpliers: a manual tool used to hold, fix or reverse, bend or cut wires. The shape of the clamps is v, usually consisting of three parts of the handle, the cheek and the mouth。
The correct selection of manual tools:
1. Prioritization of wrench according to type of work
A. Package wrench
B. Plum wrench
C. Open wrench
D. Activity wrench
2. The tool wrench can work in various ways, depending on the choice of the workplace, depending on the handle:
A. The handle of the thorn wheel (used in narrow space but with a small distortion distance)
B. Slide handles (highest speed)
C. Rotating handles (which work quickly but are difficult to use in narrow spaces)。
3. Select a tool by the size of the spin-sharp
A. The longer the handle, the greater the twist with less force
B, but with a super-long handle, there is a risk that the bolts may be broken。
Attention
1. Wrench tools:
(1) use should be based on a screwdriver, the shape of the nut, specifications and working conditions, selected with a wrench appropriate to the specifications
(2) the operation shall be carried out in such a way that the pull is on the thicker side of the opening so as to prevent the opening having an “eight” font, damaging the nut and wrench。
(3) no wrench other than a drum wrench can be fitted with a force multiplier to prevent damage to the wrench or screwdriver。
2. Pyramids:
(1) an appropriate screwrix shall be selected on the basis of the width and shape of the contour head of the spiral or loose screw
(2) no screws should be held tight or loose with screws on the piece of work in hand, and the piece of work should be contained in a bind to prevent injury
(3) no objects may be pryed with screwrs or metal pricks and other objects。
3. Hammers and handpliers:
(1) when a hammer is used, a careful examination shall be made of the strength of the hammer head and handle connection and the hammer shall be held at the back end of the hammer. There are three ways to swing hammers: wrists, elbows and arms。
A. Wrist swinging only with wrists for hammering, with small but steady, fast and low-power
B. An arm wave with a wrist, elbow and full arm, with the greatest hammering power
C. Elbow swings with wrists and elbows
(2) the use of handpliers shall be limited to the purpose for which they are designed: to tighten or cut, and never to use handpliers to untie the nut。
Jack
A jack is a light lifting device with a steel top lift as a working device, which is lifting weights at the top of the journey through a top beam or bottom claw. It's mechanical and hydraulic. The hydraulic jack structure is compact, working smoothly and self-locking, and is used extensively. The disadvantage is limited lifting height and slow up。
Usage method: for example, hydraulic jacks:
(1) before a top car, clean the top of the jack, tighten the hydraulic switch, place the jack at the bottom of the top and place the jack vertically with the top in case of an accident。
(2) rotation of the top screw, changing the original distance between the top of the jack and the top, so that the height of the top meets the ceiling height required by the car。
(3) the tripoding of the car around the wheel in order to prevent a slide accident during the lifting。
(4) pressure on the jack handle with the hand, which is gradually raised to a certain height by the top vehicle, which is placed on the shelf and is prohibited from carrying vehicles with fragile objects such as bricks. Upon disembarkation, the vehicle should be checked for obstacles and the safety of the operator should be ensured。
(5) the smooth and smooth fall of the vehicle and its steady stooling。
Attention
(1) the car is prohibited from operating under the roof of the car in the process of roofing or falling。
(2) the vehicle shall be slowly reduced and the vehicle shall not decline too fast, otherwise it will be prone to accidents, as a result of swirling the hydraulic switch。
(3) when a jack-top car is used on a loose road, a large area of pressure-resistant material (e. G. Planks) should be attached to the bottom of the jack to prevent the heavy pressure of the jack from sinking. The jacks are in the right and solid position with the car。
(4) when the hydraulic switch is in a state of convulsion after the jack has been put to the top of the car, the cause of the automatic breakdown shall be immediately identified and the failure shall be resolved in a timely manner before it can be continued。
(5) in the case of oil shortages on the jacks, the specified fluids shall be replenished in a timely manner and may not be replaced by other fluids or water。
(6) the jack shall not be warmed by fire in case of damage to the leather bowl or the ring。
(7) the jacks shall be vertically placed to avoid failure due to leakage of the fluid。
Car lift
Vehicle lifts are equipment used to lift vehicles during their maintenance, and vehicles are driven to lift positions, which can be manually carried up to a certain height to facilitate vehicle maintenance. Lifters can generally be divided into three main categories by function and shape: two columns, four columns, and shears。
Use of caution
(1) the total mass of the vehicle cannot be greater than the lift capacity。
(2) the centre of gravity of the vehicle shall be as close as possible to that of the lifter, depending on the type of the vehicle and the place where the vehicle is to be parked; and the weight of the guard shall be such that, in order to open the door, there shall be a distance between the vehicle and the pole。
(3) turning, stretching, adjusting the lifting arm to the designated position of the vehicle's chassis and exposure。
(4) before a car is lifted, the operator shall inspect the vehicle for any obstacles and movement of persons in order to prevent accidents。
(5) when a vehicle is lifted, it shall be repeated at a lower position from the ground and shall not be lifted to the required height until there is no anomaly。
(6) when the vehicle is lifted, it shall drop above the thorny teeth and be immediately locked。
Crane
The commonly used cranes are of four types: door, arm, one-track and beam. The most frequently used in manual training in carbreaking is the crane with a single arm, which is divided into two main categories: mechanical and hydraulic。
(i) mechanical cranes: the lifting or lowering of heavy matter by condensing or placing a chain of irons by turning the winch and the thorns through the handle may be carried at short distances。
(2) hydraulic crane: when hung, because of the role of the pump, the pressure oil enters the working tank, pushes the top pole outside and lifts the weight. Open the valves, and the oil in the work tank flows back to the tank, reducing the pressure, which reduces the weight。
Attention to use of lifting equipment:
(1) the lifting of heavy loads shall not permit exceeding the rated load。
(2) steel cords and buttons shall be robust。
(3) the suspension shall be as close as possible to the ground to reduce shaking. When handing over the suspension, it must be smooth and urgent。
(4) the use of cranes tow the suspensions within the range。
Specialized tools
Pistols to unplug
Pistols are used as a tool to remove the piston rings and to avoid the disequilibria of the piston rings. Use of attention:
1. When a piston ring is used to unload the piston, the ring card on the piston ring loader is stuck to the piston opening, the handle is held slightly and evenly, and the hand handle is reduced slowly, and the piston is opened slowly so that the piston ring can be removed or loaded from the piston slot。
2. When a piston ring is used to remove the piston ring, the force must be even, so as to avoid excessive force leading to the breaking of the piston ring, while also avoiding hand injuries。
The air-gate springs
Gas-gate springs are used as a tool to detach gas-gate springs. When used, the break-up stand will hold up to the gas door, press the ring to the main air-gate spring, and then press the handle to compress the air-gate spring. At this point, it is advisable to sell the air-gate springs or the locks, slowly unloading the handles, i. E., the air-gate springs, the air-gate springs, etc。
Puller
The tractor is a specialized tool for dismantling parts such as gears or bearings installed on axes that have been excessed. The tractors are commonly manual, with pressure screws and claws on one bow fork. When used, a pad is drawn between the axis and the pressure spiral, the gear or bearing is held by the tractor's claw, and the pressure spiral is tightened so that excess gears, such as gears, can be pulled from the axis to install the parts。
Slut gun
The lubricant gun, also known as the butter gun, is a tool specifically designed for lubricating lubricant ( butter). The methods used are as follows:
(1) load butter
1 pulls out the pole and moves behind the pole, wringing down the hood of the fat barrel。
2 clean butter in groups, with seo xu loaded in the cylinders, and made it possible to keep each other as close as possible to facilitate the discharge of air from the cylinders。
3 reload the forecap, push it back to the pull pole and move the piston forward with spring action, thus keeping the butter compressed。
(2) oil injection method
One is to turn the lubricated butter beaks (slubber beaks) against the lubricated butter beaks and to go straight out, without being tilted, in order not to affect the bets and reduce the waste of lubricant。
2 when oil is not contained, it shall cease immediately and the reasons for the congestion shall be identified, and the oil shall be removed and re-injected。
(3) the main reason why oil is not fed when lubricated
1 there is no air in butter or butter in pressure tanks。
2 liquor gun pressurized oil valves blocked or plugged in the fillings。
3 the lush spring is too soft, resulting in insufficient or broken springs。
