Problems solved by technology
During use, as the spreader enters the electrophoresis more and more times, the electrophoretic fluid on the two surfaces also accumulates more and more, and the gap between the eccentric pin and the inner hole of the base is filled with electrophoretic fluid, and the eccentric pin is easy to It is stuck by the electrophoretic fluid and cannot rotate smoothly, so it is impossible to lock and unlock the body

Embodiment Construction
[0013] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:
[0014] like Figure 1~2 As shown, the present invention mainly includes an eccentric pin seat 1 , a support arm 2 , a rotating mechanism 3 and an eccentric pin 5 .
[0015] The support arm 2 is connected with the eccentric pin seat 1 by bolts, and the eccentric pin seat 1 is connected with the eccentric pin 5 in rotation. The lower end of the eccentric pin 5 is connected to the rotating mechanism 3 by a flat key, and the rotating mechanism 3 is fixed on the rotating mechanism fixing bracket 4 by bolts. When working, the rotating mechanism 3 drives the eccentric pin 5 to rotate in the eccentric pin seat 1 .
[0016] The rotating mechanism 3 is a motor or an air cylinder.
[0017] An outer spacer 6 and an inner spacer 7 are arranged between the eccentric pin 5 and the eccentric pin seat 1 , and the inner spacer 7 is located at the inner ring of the ou...

The invention relates to an anti-jamming eccentric pin locking mechanism, in particular to a device for positioning and locking an automobile body on an automobile coating workshop pretreatment electrophoresis line, and belongs to the technical field of automobile body treatment equipment. The anti-jamming eccentric pin locking mechanism comprises an eccentric pin base, a supporting arm, a rotation mechanism and an eccentric pin. The supporting arm is connected with the eccentric pin base through a bolt. The eccentric pin base is internally rotationally connected with the eccentric pin. The lower end of the eccentric pin is connected with the rotation mechanism through a flat key. An outer isolation sleeve and an inner isolation sleeve are arranged between the eccentric pin and the eccentric pin base, and the inner isolation sleeve is located on the inner circle of the outer isolation sleeve. The anti-jamming eccentric pin locking mechanism is simple, compact and reasonable in structure, the eccentric pin of the locking mechanism can be prevented from being jammed by electrophoresis liquid, the service life is prolonged, the occupied space is reduced, and meanwhile the production cost is reduced.
Description
technical field [0001] The invention relates to an anti-blocking eccentric pin locking mechanism, in particular to a device for positioning and locking a car body on a pre-treatment electrophoresis line in an automobile painting workshop, and belongs to the technical field of car body processing equipment. Background technique [0002] In the automobile painting workshop, the first process that the body goes through is the pretreatment-electrophoresis process. Its main function is to clean the body first, then phosphate, and then enter the electrophoresis tank for electrophoresis on the surface of the body, so that it will be on the body The first protective film is formed on the surface. Therefore, in the pre-treatment-electrophoresis station, the body must always enter the imported liquid. Due to the buoyancy of the liquid, in order to prevent the body from being separated from the spreader body under the buoyancy and impact of the liquid in the liquid, we need to lock th...
