Automatic assembly device for angle adjuster disc spring of automobile seat

Abstract

The invention relates to an automatic assembly device for an angle adjuster disc spring of an automobile seat, which is used for assembling a disc spring on a seat backrest. The device comprises a backrest supporting and positioning mechanism for supporting the seat backrest and positioning the seat backrest, a disc spring tightening mechanism, a disc spring pushing mechanism, and a moving mechanism which is connected with the disc spring pushing mechanism and is used for driving the disc spring pushing mechanism to slide towards a right lug plate or away from the right lug plate. By adopting the automatic assembly device, full-automatic assembly operation of the disc spring for the seat backrest is realized, the assembly process of the disc spring is safe and stable, the impact on inner and outer supports of the disc spring of the seat backrest is very small, the noise is extremely low, the labor work of operators is eliminated, and a good working environment is provided for workers.

Description

technical field [0001] The invention relates to an assembly device of an automobile seat accessory, in particular to an automatic assembly device for a coil spring of an automobile seat recliner. Background technique [0002] The car seat recliner is a device that adjusts the angle between the seat cushion and the backrest. By adjusting the angle of the backrest, the comfort of the driver and passengers can be improved. [0003] In the above-mentioned recliner, the coil spring is the most important component part. Usually, the center of the coil spring coincides with the axis of the backrest shaft, and the backrest is always affected by the torque of the coil spring during the whole stroke. When the recliner is unlocked, the coil spring will automatically tilt the backrest forward, and the driver and passengers can tighten the coil spring when they push backwards, so that the backrest can be tilted backward. When the coil spring is fully contracted, the backrest can be in a ...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the car seat factories at home and abroad use the coil spring of the seat recliner to be manually assembled, that is, the worker puts the coil spring on the backrest shaft, then tightens the coil spring with the help of a power tool, and uses the skill to assemble the coil spring in place. When the coil spring is buckled into the coil spring inner slot and the coil spring outer support structure, there will often be a lot of noise, and there is also a great risk of accidents during the assembly process. A slight misoperation may cause the coil spring to collapse and fly, thereby It will cause great harm to the assembly workers
