1) A screwdriver.

2) Cruciform driver.

3 Hand hammer and pliers:

1) Fitter hammer.

2) Carp pliers and wire cutters.

3) Needle-nose pliers.

Precautions for using tools:

1 Wrench Tools:

1) The opening size of the selected wrench must be consistent with the size of the bolt or nut, the wrench opening is too large and easy to slip off and damage the hexagonal screw of the nut. The selection principle of various types of wrenches is generally preferentially the sleeve wrench, followed by the plum wrench, the open wrench, and finally the movable wrench.

2) In order to prevent the wrench from being damaged and slipping, the tensile force should be acted on the thicker side of the opening, which should be especially paid attention to the movable wrench with greater force, in case the opening appears in a zigzag shape, damaging the nut and the wrench.

3) The ordinary wrench is designed according to the strength of the human hand, and the wrench cannot be hammered when encountering a tighter threaded piece; With the exception of socket wrenches, other wrenches should not be equipped with afterburner rods to prevent damage to the wrench or threaded connections.

2 Screwdriver:

The selection of model specifications should be based on the width of the groove, and should not be operated with electricity; When using, in addition to applying torsion, appropriate axial force should also be applied to prevent slippage and damage to the parts; Do not pry anything with a screwdriver.

3 Hand hammer and pliers:

1) When using the hand hammer, remember to carefully check whether the hammer head and hammer handle are firmly wedged, and the hammer should hold the back of the hammer handle. There are three ways to swing the hammer, the wrist swing, the small arm swing and the big arm swing, the wrist swing hammer only moves the wrist, the hammer force is small, but accurate, fast, labor-saving, the big arm swing is the big arm and the small arm move together, the hammer force is the largest.

2) Do not use hand pliers instead of wrenches to tighten the threaded connection above m5 to avoid damage to the nut or bolt.

Disassembling the license plate also depends on what license plate is dismantled, which can be divided into: anti-theft license plate, with anti-theft screws, it will be more convenient for a sheet metal master to operate with professional tools; Ordinary license plates, as long as you can hold a screwdriver, it should be no problem.

Each part of the car has its own disassembly and assembly tools, and it is best to explain which place.

Car disassembly tools include screwdrivers, sockets, and wrenches. Commonly used are Shida 128-piece set of tools.

Commonly used automobile disassembly tools are: all kinds of wrenches, screw screws, hand hammers, pliers, jack calendar comics, car lifts, lifting cranes, piston ring disassembly pliers, valve spring disassembly frames. Selection principles for all kinds of wrenches:

Generally, the socket wrench is preferred, followed by the torx wrench, then the open wrench, and finally the movable wrench. Ordinary wrenches are designed according to the strength of human hands, and the wrench cannot be hammered when encountering tighter threaded parts, except for the socket wrench, other wrenches cannot be equipped with afterburner rods to prevent damage to the wrench or threaded connectors. When using a hand hammer, remember to carefully check that the hammer head and hammer handle are wedged firmly, and that the hammer should be held against the back of the hammer handle.

There are three ways to swing the hammer, the wrist is rotten posture swing, the small arm swing and the big arm swing, the wrist swing hammer only moves the wrist, the hammer force is small, but accurate, fast, and labor-saving, the big arm swing is the big arm and the small arm move together, and the hammer force is the largest.

The interior and exterior trim removal tool is used to disassemble various specifications of rubber caps and buckles.

Its main method of action is to pry open the buckles of various interior and exterior trims. As shown in Figure 73, the opening of the internal and external trim disassembly tool is snapped into the neck of the trim rubber cap or buckle, and the rubber cap, buckle can be pried out outward with a little force. The interior and exterior trim removal tool is used to disassemble various specifications of rubber caps and buckles.

Its main method of action is to pry open the buckles of various interior and exterior trims. As shown in Figure 73, Brother Lu, the opening of the internal and external trim disassembly tool is stuck into the neck of the rubber cap or buckle of the ornament, and a little force can be used to pry out the rubber cap and buckle.

1. Principles and methods of disassembly and assembly.

The purpose of disassembly is to inspect and repair the parts of the automobile, so as to maintain the assembly that needs to be maintained, or to repair or replace the defective parts, so that the parts with abnormal fitting relationship can be adjusted to meet the specified technical standards. The following principles should be followed when disassembling:

1.Familiar with the structure and working principle of the carThere are many types of cars, different structures, different disassembly sequences and different tools used. If you do not understand the structural characteristics of the car, arbitrarily disassemble it, which will cause damage or deformation of the parts, and you will not be able to carry out qualified assembly of the car.

2.Disassemble as needed, do not blindly dismantle the parts, and try not to disassemble if the technical condition of the parts can be determined whether the technical condition meets the requirements without disassembling and inspecting. Because in the process of disassembling parts, the parts are more or less deformed, especially the tightly fitting parts.

3.Master the correct disassembly method.

1) Special tools and equipment should be used during disassembly to improve the disassembly efficiency and avoid damage and deformation of parts.

2) Disassemble from the surface and the inside in order step by step. Generally, the carriage, external circuits, pipelines, accessories, etc. are dismantled first, and then disassembled in the order of one assembly, one component, one assembly and one part of the machine.

4.Be prepared for reassembly when disassembling.

1) When dismantling, pay attention to checking and proofreading the assembly mark, in order to ensure the assembly relationship of some components, the original mark should be proofread and identified when dismantling. If there is no mark or the mark is not clear, it should be re-checked and marked.

2) The parts should be classified and placed in order. In order to facilitate cleaning, inspection and assembly, the parts should be classified and placed in order according to different requirements. The parts of the same assembly and component should be placed centrally; Non-interchangeable parts should be placed in pairs; Parts that are easily deformed and lost should be placed in the corresponding container.

5.Removal of threaded connectorsThreaded connectors are the most common connectors in disassembly. Generally speaking, it is relatively easy to disassemble the threaded connection, but if you do not pay attention to the disassembly method, it will also cause damage to the parts. For more information about automobile chassis, please refer to the website for details.

1) The disassembly method of the threaded connector adopts a suitable socket wrench or fixed wrench (according to the size of the tightening torque on the bolt, the socket wrench, the plum wrench and the dull wrench are selected in turn). When it is difficult to disassemble, the reasons for the difficulty should be analyzed, and it should not be done brutally. The wrench should not be arbitrarily lengthened to increase the disassembly torque, as this will cause damage to the connector or break the bolt.

Necessary tools: a feeler gauge and a steel plate ruler;

That's more, what kind of car are you asking, big car or small car?

What are the methods for correcting the local deformation of body components?

Answer: Hammering method: use sheet metal hammer, top iron, leveling knife and other tools to force the drum convex to shrink back by percussion and extrusion, so that the deformation can return to its original shape.

Suction and pull method: use suction cups or pull rods to repair large depression damage or small pits with elastic deformation without disassembly. 、

Inertial hammer method: the impact force of the inertial hammer is applied to the deformed part through the positioning device, which is the deformation and damage are repaired Traction method: with the traction of external force, the correction of the deformation or more serious deformation of the skeleton, beam, fender, threshold and other components is realized, and the support method: the deformation top of the frame member is pressed into the ideal position by using the supporting force of the support lever that can be extended. It is mainly used for the extrusion deformation of open frame body structure.

When disassembling the body to build, a series of tools such as lock nuts, wrenches, and Phillips screwdrivers are required.

Wrenches, pliers and other tools, are you going to unload the car?

Generally conventional toolboxes, or hardware screwdrivers, disassembly knives, etc.
