[0003] Therefore, our company has designed a device for automatic assembly of vehicle lock torsion springs by analyzing the actual production and assembly of door lock torsion springs. Summary of the invention

[0004] The purpose of the present invention is to provide a device for automatically assembling a vehicle lock torsion spring. The present invention not only meets the requirements of automated assembly line production, but also has the characteristics of high interchangeability, reasonable structure, good stability, and easy installation and maintenance.

[0005] The technical solution of the present invention is as follows: a device for automatically assembling a torsion spring for a vehicle lock, comprising a door lock torsion spring straight vibration track, a torsion spring slideway end block is installed at the end of the door lock torsion spring straight vibration track, a magnetic induction switch is provided on the torsion spring slideway end block, a torsion spring flip block is provided on the torsion spring straight vibration track on one side of the torsion spring slideway end block, a torsion spring clamp is provided on the upper side of the torsion spring flip block, the torsion spring clamp is connected to a clamp cylinder, and the clamp cylinder is fixed on a moving device.

[0006] In the aforementioned automatic assembly device for vehicle lock torsion springs, a clamp is provided below the torsion spring clamping jaw, a detection torsion spring mounting block is installed on the rear side of the clamp, and a second magnetic induction switch is provided on the detection torsion spring mounting block.

[0007] In the aforementioned device for automatic assembly of torsion springs for vehicle locks, a groove equal to the rotation angle of the torsion spring is opened on the torsion spring clamp, and an adjusting screw is provided on the torsion spring clamp. When the magnetic induction switch 1 senses the torsion spring, the torsion spring flip block works, and the torsion spring flip block pushes the middle extended part of the torsion spring to rotate at an angle equal to the angle of the groove on the torsion spring clamp; when the torsion spring clamp takes the torsion spring, the magnetic induction switch 13 does not sense the torsion spring, and the torsion spring flip block returns to the initial position; the adjusting screw is used to adjust the pre-compression stroke of the torsion spring clamp, and the structure is simple, the adjustment is convenient, and the reliability is strong.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The present invention provides a device for automatically assembling torsion springs for vehicle locks. First, vehicle lock torsion springs of the same specification are placed in a torsion spring vibrating conveyor plate, so that the states of the torsion springs entering the straight vibration track meet the requirements, and the torsion springs are conveyed to a designated position to be determined. After the magnetic induction switch detects the torsion spring, a signal is given to make the torsion spring flipping block push the torsion spring to flip, and at the same time, the moving device is controlled to drive the torsion spring clamp to take the torsion spring to be determined, and put it into the designated position of the lock core on the fixture, so as to realize the automatic assembly of the vehicle lock torsion spring. At the same time, the magnetic induction switch 2 will sense the torsion spring on the lock core to prevent the torsion spring from being installed in place or missing the torsion spring, so as to achieve not only the satisfaction of automated assembly line production, but also the high interchangeability, reasonable structure, good stability, and easy installation and maintenance.

[0012] 2. The present invention improves the assembly efficiency of torsion springs, reduces production costs, provides a basis for automated assembly line operations, ensures the consistency of batch products, and has obvious efficiency improvements. The original manual assembly is changed to automated production, doubling the production efficiency and saving about 167,000 yuan in labor costs each year.

[0024] The torsion spring clamp 5 is provided with a groove equal to the rotation angle of the torsion spring, and an adjusting screw 7 is provided on the torsion spring clamp 5. When the magnetic induction switch 3 senses the torsion spring, the torsion spring flip block 4 works, and the torsion spring flip block 4 pushes the middle protruding part of the torsion spring to rotate at an angle equal to the angle of the groove on the torsion spring clamp 5. After the torsion spring clamp 5 clamps the torsion spring, the magnetic induction switch 3 does not sense the torsion spring, the torsion spring flip block 4 works, and the torsion spring flip block 4 returns to its initial position. The adjusting screw 7 is used to adjust the pre-compression stroke of the torsion spring clamp 5, and has a simple structure, convenient adjustment, and strong reliability.
