Automotive beam calibrator

Abstract

The invention discloses an automotive beam calibrator, which comprises a pull tower, a main platform, two lifting boxes and a chassis. The pull tower is provided with a moving mechanism, a positioning mechanism and a locking mechanism. The moving mechanism comprises a front guide wheel group and a rear guide wheel group. The positioning mechanism comprises a platform gland which is provided with a positioning pin. A positioning hole matched with the positioning pin is formed on the main platform. The locking mechanism comprises a floating connecting rod which is connected with the platform gland, a driving connecting rod which is connected with the floating connecting rod, a platform gland driving handle and a safety limit handle. The driving connecting rod and the driving handle are assembled on the safety limit handle through a pin shaft. The pull tower can move at any position of a main platform track by 360 DEG, so the positioning is precise, and the pull tower can be locked on the main platform rapidly for stretching. Meanwhile, the pull tower can be unlocked and released quickly so as to freely move. Therefore, the operating mode of the pull tower is greatly improved, the working efficiency is improved, the operation is safer and more reliable, and rapid and high-efficiency automotive stretching repair is realized.

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
