Abstract

The invention provides an automotive suspension disassembly and assembly device and a disassembly and assembly method thereof. The automotive suspension disassembly and assembly device comprises an upper plate and a lower plate, wherein the upper plate and the lower plate are connected through at least one vertical column. The upper plate is provided with a movable plate and a locating pin, one end of the movable plate is connected with the upper plate through a bolt, an installation hole matched with the locating pin is formed in the other end, and a hole is formed in the middle of the upper plate. The lower plate is provided with a jack and a rocking lever used for controlling the height of the jack. The automotive suspension disassembly and assembly device has the advantages that the operation is easy, convenient, safe and reliable. The disassembly and assembly process of a suspension is simple, and the automotive suspension disassembly and assembly device can be used without training. In addition, the automotive suspension disassembly and assembly device can bear large compression force and restoration force, is stressed uniformly, and is safe and reliable.

Description

technical field [0001] The invention relates to an automobile suspension disassembly device and its disassembly and assembly method, in particular to a portable automobile suspension disassembly device and its disassembly and assembly method. Background technique [0002] In the maintenance area and test area of ​​the automobile industry, frequent disassembly and assembly of the suspension assembly is usually required to complete the maintenance and replacement of the automobile suspension assembly or parts, road test and adjustment and debugging. Therefore, in order to effectively complete the above work, it is necessary to use appropriate auxiliary tools to assist technicians in disassembling and assembling the suspension assembly. [0003] At present, domestic automobile suspension disassembly and assembly devices mainly use clamping and compression coil springs to realize suspension disassembly and assembly. Patent name: An improved automobile suspension coil spring dis...

AI Technical Summary

Problems solved by technology

[0004] (1) The safety and versatility of the device in this patent is not good: the structure and specifications of the coil spring of the automobile suspension are various, but the structure of the pull claw in the device cannot be applied to springs with different spring diameters. During the process, it may cause unstable clamping. In addition, the spring stiffness is generally relatively large. When the spring is compressed, it may pop out suddenly, causing adverse consequences of injuring others.

[0005] (2) The device in this patent is easy to damage parts: the device directly uses the claws to clamp and compress the coil spring, because the clamping force of the coil spring is very large when the coil spring is compressed, it is easy to damage the surface of the spring

[0006] (3) The device in this patent is operated with low work efficiency and high labor intensity

And it cannot be used alone, it must be used in pairs. When using it, the two sides of the spring must be gradually and evenly compressed, otherwise the spring will be unevenly stressed and the compression amount on both sides will be different. Not only can the disassembly and assembly of the suspension not be completed, And there are potential safety hazards, so the actual operation efficiency is low

In addition, since the device does not have an auxiliary force device, the labor intensity is increased

[0007] (4) The device is inconvenient and inflexible to operate: the coil spring has a coil lift, and the suspension assembly is disassembled only by compressing the spring, so it is difficult to ensure the shock absorber piston rod, spring and spring seat, etc. Perfect alignment, which will affect the smooth assembly of other components in the suspension

[0009] (1) The device is easy to damage parts. Although the device in the patent adopts the method of clamping and compressing the coil spring at one end, the clamping force directly acting on the spring is still very large, and the surface layer of the spring is easily damaged.

[0010] (2) The actual operation of the device is complicated and the efficiency is not high

This patent is composed of multiple parts, and the structure is quite complicated. Many steps are required to clamp the shock absorber and the spring. It is not labor-saving to operate the handle to compress the spring, and it is easy to get stuck after a long time.

[0011] (3) The device is expensive to manufacture, takes up a lot of space, and is not easy to move or carry
