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:
1. Drive unit
Working principle: The motor drives the two gears to rotate through
the coupling, and the two gears respectively drive the moving
skateboard to move through the parallel racks meshing with it,
thereby driving the body side panel mounted on the moving
skateboard to move horizontally.
2. 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.
