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:

Synchronous rack device and jacking device

Working principle: The cylinder drives the "active gear" in the jacking device to rotate through the "active cylindrical gear bar", thereby driving the "driven cylindrical gear bar" to move, and indirectly pushing the "jacking frame" to move up and down, realizing the horizontal movement to The conversion of the vertical movement achieves the purpose of freely lifting the side panel of the vehicle body. In addition, the part 6 (support guide cylinder) in the synchronous rack device mainly plays the role of guiding and ensuring that the active cylindrical gear bar is always meshed with the driving gear in the jacking device; part 5 (anti-rotation angle iron) mainly plays the role of preventing the active cylindrical gear The role of the gear bar rotation. Part 1 (auxiliary thrust cylinder) in the jacking device mainly plays the role of equalizing vertical motion thrust.
