Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a spring lever device capable of realizing automatic tipping of fixtures. Background Art

[0002] During the vehicle production and assembly process, the rear suspension assembly needs to be assembled. According to the installation positioning accuracy requirements of the rear suspension and the vehicle body, two left and right positioning pin fixtures are respectively configured on the rear suspension assembly plate to assist in alignment and assembly.

[0003] Due to the high height of the positioning pin fixture, after the assembly is completed, the empty platen will collide with the conveyor line when returning, causing the empty platen to be stuck, causing abnormal chain stop, and directly affecting production efficiency. At present, the assembly post employees are arranged to manually pull out the fixed pins in the positioning pin fixture after the assembly operation is completed, and then overturn the two positioning pin fixtures on the left and right, which increases the labor load of the operation and poses a certain risk of occupational disease hazards; if the fixture is forgotten to be overturned for a while, it will cause multiple collisions and interferences between the fixture and the conveyor line, and the platen will be blocked, which not only reduces production efficiency and affects the output, but also increases the cost of fixture spare parts and equipment spare parts; the maintenance of the conveyor line is cumbersome and complicated, further increasing the loss of man-hours.
