Problems solved by technology

This kind of process has the following problems: ① There is still internal stress inside the shaft seat that has just been taken out of the injection molding machine. Resulting in the increase of defective products in batch products and the decrease of yield rate; ②Due to the different magnitude of manual force during the hot pressing process, the cross-sectional position of the contact cone surface of the shaft rod and the shaft seat after pressing is different, and the torque is detected after standing for a period of cooling When the torque of the assembly product occurs during the rotation, the phenomenon of unevenness and instability will occur
③ Time-consuming and unsafe for the human body

Abstract

The invention discloses a laminating, rotating and returning device of a shaft lever assembly for assembling a shaft lever and a shaft base of an automobile sun shield. The device comprises a rotary mechanism which is used for driving a lower carrier to rotate and return; the rotary mechanism comprises gears fixed on an upper carrier, racks driving the gears to rotate, and a second air cylinder fixed on a sliding plate and used for driving the racks to advance and retreat. Compared with the prior art, through adding the rotary mechanism, the internal stress of the shaft lever and the shaft base can be immediately eliminated after laminating, so that the resistance of the shaft lever assembly in using rotation angle range is uniform.

Description

【Technical field】 [0001] The invention relates to the technical field of automobile parts manufacturing, in particular to a device for improving the torque stability during the assembly process of an axle rod and an axle seat of an automobile sun visor. 【Background technique】 [0002] Such as Figure 6 , the axle rod assembly 4 of the automobile sun visor is assembled by the axle rod 41 and the axle seat 42, wherein the axle seat 42 is fixed in the vehicle body, and the axle bar 41 is installed in the axle seat 42 and can rotate. In the general industrial production process, since the shaft assembly of the automobile sun visor needs to meet a certain range of torque detection conditions, this makes the assembly of the size of the shaft and the size of the hole in the corresponding part of the shaft seat an interference fit. An assembly method carried out under the circumstances. In the past, the shaft seat just taken out of the injection molding machine was used to insert t...
