Automotive shock absorber set correction device

Abstract

The invention discloses a correction device for an automobile damping assembly. The correction device comprises a supporting base; a vertical plate and a boss are arranged on the supporting base; a guide way is arranged on the front end face of the vertical plate; a limiting supporting column, an upper clamp and a lower clamp are arranged in the guide way; the upper clamp comprises an upper supporting column and an upper clamping part; the lower clamp comprises a lower supporting column and a lower clamping part; the upper supporting column is provided with a first threaded hole in the vertical direction; the lower supporting column is provided with a second threaded hole in the vertical direction; the internal thread direction of the first threaded hole is opposite to that of the second threaded hole; a first threaded rod is arranged in both the first threaded hole and the second threaded hole; and a ratchet mechanism is arranged in the middle of the first threaded rod. According to the correction device for the automobile damping assembly, by means of the limiting supporting column, the upper clamp and the lower clamp arranged on the vertical plate, dampers which are differently sized can be limited, installation is simple, operation is convenient, and the correction device is suitable for correction operation of damping assemblies with different models and sizes.

Description

technical field [0001] The invention belongs to the technical field of automobile maintenance, and in particular relates to an automobile shock absorbing set correction device. Background technique [0002] The car shock absorber is one of the important parts of the car. It effectively reduces the vibration of the frame and the body during the running of the vehicle, which is of great significance to the smoothness and comfort of the car. The car shock absorber usually includes shock absorbers and Spring, during the long-term use of the vehicle, the shock-absorbing set is used as a buffer component to bear the impact force generated by the vibration of the vehicle body, and is a vulnerable part. Driving on roads with poor road conditions for a long time or due to bad driving habits (frequently stepping on the brakes and slamming on the accelerator) will cause irreversible deformation of the spring and shorten the spring stroke, which not only affects the comfort of the vehic...

Problems solved by technology

Driving on roads with poor road conditions for a long time or due to bad driving habits (frequently stepping on the brakes and slamming on the accelerator) will cause irreversible deformation of the spring and shorten the spring stroke, which not only affects the comfort of the vehicle, but also lasts for a long time. Use will cause wear and tear between the spring and the shock absorber and cause abnormal noise. At this time, it is necessary to correct the spring to prevent oil leakage from poor sealing of the shock absorber. However, there are the following technical problems when correcting the spring: due to There are differences in the model of the suit, such as the difference in the diameter of the spring, the difference in the diameter of the two ends of the same spring, the difference in the material, outer diameter and surface treatment of the spring steel, and the multiple parts of the shock absorber. For example, the size of the sleeve and the piston, the structure of the spring pressing plate 30 and the carrier 26 are different (such as figure 1 ball bearing and U-head bearing shown)

The disadvantage of this structure: the device is only used for fixing the shock absorber or the shock absorber, and is not suitable for the installation of the spring and the shock absorber, and the shock absorber is manually pushed into the two jaws during use In the process of advancing, due to the strong elastic force of the self-returning spring, the operator at this station has a relatively large workload
