Integrated unit for automatically assembling torsion springs

Abstract

The invention discloses an integrated unit for automatically assembling torsion springs. The integrated unit comprises an A torsion spring feeder (1), a B torsion spring feeder (2), a pressure spring unit (3), torsion spring clips (4) and a base plate (5). When the integrated unit consisting of the mechanisms works, torsion springs are supplied by the torsion spring clips; a torsion spring A and a torsion spring B are respectively fed to corresponding mounting positions by virtue of the A torsion spring feeder and the B torsion spring feeder; an airbag seat is fed to a set position by virtue of the pressure spring unit, and the torsion spring A and the torsion spring B are pressed into the airbag seat. According to the technical scheme, the plurality of torsion spring clips are arranged for repetitive use, so that only the torsion spring A and the torsion spring B are required to be manually fed into the torsion spring clips respectively, and the torsion spring clips without the torsion springs are timely replaced correspondingly, and therefore, torsion spring assembly can be continuously carried out; and the torsion spring assembly for an automotive airbag seat achieves the purposes of relieving working strength, improving efficiency, reducing labor, reducing cost and improving quality.

Description

technical field [0001] The invention relates to an automatic assembly device, in particular to a joint device for automatically assembling torsion springs for assembling the torsion springs on the base of an automobile safety airbag. Background technique [0002] Automobile airbag base, referred to as the airbag seat, the airbag seat needs to be installed with two kinds of torsion springs, A torsion spring and B torsion spring. The existing technology is assembled manually with the help of hand tools, because the A torsion spring and the B torsion spring have different shapes. However, it is complex and has a large torsion force. Each person can only complete the assembly of 200 torsion springs of airbag seats in 8 hours, and it is easy to reverse or misassemble. Low efficiency, more labor, high cost, and poor quality. In addition, due to the large torque of the torsion spring and the high intensity of assembly, it is easy to cause fatigue and injury to the operator's hand. ...

[0002] Automobile airbag base, referred to as the airbag seat, the airbag seat needs to be installed with two kinds of torsion springs, A torsion spring and B torsion spring. The existing technology is assembled manually with the help of hand tools, because the A torsion spring and the B torsion spring have different shapes. However, it is complex and has a large torsion force. Each person can only complete the assembly of 200 torsion springs of airbag seats in 8 hours, and it is easy to reverse or misassemble. Low efficiency, more labor, high cost, and poor quality. In addition, due to the large torque of the torsion spring and the high intensity of assembly, it is easy to cause fatigue and injury to the operator's hand. The production line often uses a one-week rotation system, which makes the operator's hand The changing of the guard can be resumed. Therefore, the prior art has the problems and deficiencies of high work intensity, low efficiency, many labors, high cost, and poor quality.
