Analysis on the structure and working principle of the transmission device of the automobile welding production line

The following takes the transmission device of the automobile side panel assembly line as an example to analyze its structure and working principle in detail

The transmission device of the side panel assembly line of a certain vehicle type adopts a four-station reciprocating rod device, which can realize horizontal and vertical movement. The structure and function analysis of each sub-assembly is as follows:

Buffer locking device

A total of 4 buffer locking devices are installed in the welding line transmission device, which are respectively distributed at both ends of the jacking frame, mainly to buffer and lock the horizontal movement of the "moving slide". The specific process is: when the "moving slide" is about to move to the end of the transmission device, it contacts with the buffer to slow down the movement speed: when the "moving slide" moves to the end of the transmission device, the travel switch commands the cylinder to clamp and fix on the moving The limit block on the slide plate thus plays a locking role. The device realizes the slow start and slow stop movement requirements of the transmission device of the automobile welding line, and ensures the safe and reliable operation of the transmission device.

safety devices

This device is set up 3 on the whole transmission device, and its main function is to jack up the whole "lifting frame" to facilitate maintenance by workers.
