Automobile girder calibration instrument

Abstract

The present invention is an automobile girder correction instrument, which includes a pull tower, a main platform, two lift boxes and a chassis, the pull tower is provided with a moving mechanism, a positioning mechanism and a locking mechanism, and the moving mechanism includes a front guide wheel and a locking mechanism. The rear guide wheel set, the positioning mechanism includes a platform gland with a positioning pin, the main platform is provided with a positioning hole that matches the positioning pin, and the locking mechanism includes a floating coupling connected to the platform gland. Rod, the drive link connected with the floating link, the platform gland drive handle and the safety limit handle, and the drive link and the drive handle are assembled on the safety limit handle through the pin shaft. The pull tower can move at any position of 360 degrees on the track of the main platform, with precise positioning, and can quickly lock the pull tower on the main platform for stretching operations. At the same time, it can also quickly unlock and release the pull tower to make it move freely. Thus, the operation mode of the pull tower is greatly improved, the work efficiency is improved, and it is safer and more reliable, realizing fast and efficient car stretch repair.

Description

technical field [0001] The invention relates to a calibrator, in particular to an automobile girder calibrator. Background technique [0002] The rapid development of my country's national economy has effectively promoted the rapid development of my country's automobile industry. Correspondingly, the auto repair industry has also developed into a huge market. As an important tool for the transportation of people and goods, accidents such as tilting, collision and overturning often occur when cars are in motion. In this case, its main load-bearing parts, the car's frame, chassis and car body are prone to displacement, twisting and other deformations. The pull tower needs to be moved along the track to the deformation place and fixed, and locked on the main platform to ensure that the pull tower does not shift when it is stretched and stressed. [0003] In the current auto repair industry, when the calibrator is used to calibrate and repair the car frame chassis, there are ...

AI Technical Summary

Problems solved by technology

[0003] In the current auto repair industry, when the calibrator is used to calibrate and repair the chassis of the car frame, there are shortcomings such as low efficiency, troublesome operation, and inaccurate positioning during the process of walking, positioning, locking and subsequent unlocking on the main platform.

The specific performance is that the moving mechanism is not flexible enough, and the moving mechanism swings when walking; the front guide wheel only supports the outer track of the main platform in the upward direction, and at the same time, there is no sliding part in the rear block, and there is a certain transverse gap relative to the inner track of the main platform , only relying on its frictional movement with the inner track of the main platform, the inner side of the pull tower is not smooth and swings; the parts of the positioning mechanism have a large matching gap, and the positioning is not accurate; the locking mechanism is complicated and the operation is troublesome; at the same time, the locking pin shaft is the same as the platform The existence of gaps between the positioning holes makes it easy to cause movement dislocation relative to the main platform when the pull tower is working under force, and accurate stretching cannot be implemented, and the sudden shift and swing when the car body is under force will cause tension clamps and other The slipping of the auxiliary parts, so that the calibration work needs to be reset continuously, so the current automobile girder calibrator pull tower walking, positioning, locking and subsequent unlocking system is time-consuming and laborious, the positioning is inaccurate, the operation is troublesome, the assembly and disassembly time is long, and the efficiency is low , poor reliability
