A locking nut is also provided, which is mainly used to lock the tensioning screw so that it will not loosen after the chain is tightened. The frame moves on the conveyor chain 4 as the conveyor chain 4 moves to the end of the conveying device. Since the conveyor chain 4 needs to turn around when it reaches the end of the circular conveying, the conveyor chain 4 forms a ring. At this time, the frame needs to continue to be conveyed to the next device. In order to ensure that the ring formed by the turning cycle of the conveyor chain 4 does not affect the smooth transportation of the frame, a transition roller is added. The second support frame 31 is close to the second support plate 121. The second support frame 31 is rotatably connected with a driven shaft 32. Three second driven sprockets 33 are sleeved on the outer surface of the driven shaft 32. The three second driven sprockets 33 are meshed with the conveyor chain 4.

The driven shaft 32 is mainly used to install the second driven sprocket 33, which rotates under the support of the slider seat bearing to transmit motion and torque.

[0032] like Figure 8As shown, in the specific implementation process, the small parts that need to be bridged are divided into multiple workstations according to the workload, the time of bridge welding and the number of personnel. The frame is manually lifted to the chain of the chain conveyor at the driving end of the conveying device, and the start switch is pressed. The conveyor chain 4 starts to move, and the frame moves with it to the first conveying support assembly 11. The first lifting cylinder 112 starts to work, and the frame is lifted up, and the conveyor chain 4 is out of contact with the frame. When the conveyor chain 4 continues to move, the frame is located on the first support rod 113 and does not move. At this time, the staff will spot weld the small parts that need to be bridged to the frame according to the requirements of the drawing, and then assemble the welding, deburr, etc. After completion, press the descending button of the first lifting cylinder 112, and the first lifting cylinder 112 descends. When the frame descends to contact with the conveyor chain 4, the frame will move with the conveyor chain 4 and move. The frame moves to the top of the next conveying support assembly 11. At this time, the first lifting cylinder 112 starts to work, the frame is lifted up, and the conveying chain 4 is out of contact with the frame. When the conveying chain 4 continues to move, the frame is located on the first lifting cylinder 112 and does not move. At this time, the staff will spot weld the small parts that need to be powered to the frame according to the requirements of the drawing, and then assemble the welding, deburr, etc., and so on. After the work content of multiple workstations is completed, the first lifting cylinder 112 of the last conveying support assembly 11 descends, the frame contacts the conveying chain 4, and the frame moves with the conveying chain 4 to the top of the cleaning support assembly 12 to start cleaning the frame tank. After the cleaning is completed, the second lifting cylinder 12224 in the cleaning support assembly 12 works, the frame contacts the chain, and the frame is transferred to the next process. The entire work process realizes streamlined operation.
