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

Taking the transmission device of the automobile side panel assembly as an example, its structure and working principle will be analyzed in detail below.

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:

The base board structure of each station

The base plates of each station are connected together through connecting plates to form the supporting device of the entire automobile welding line, which must support both the entire transmission device and the welding fixture. In addition, in order to ensure that the datum of the fixture and the body parts are consistent, draw the datum scale line on the base board according to the design datum. The leveling device in the figure mainly plays a role in leveling the entire transmission device.

The above is the main structure of the transmission device, and there are some auxiliary devices in addition:

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.

7. Safety device

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.
