Eccentric locking pin for electrophoresis sledge

Abstract

The invention relates to an eccentric locking pin for an electrophoresis sledge. The eccentric locking pin comprises a base plate, an elastic limiting device, a rotating shaft, a rotating shifting block, an eccentric hook pin, a hook pin unscrewing-state height limiting plate, a hook pin screwing-state height limiting plate and an eccentric pin height position guide rod, wherein the elastic limiting device is arranged on the upper end surface of the base plate, and the hook pin unscrewing-state height limiting plate and the hook pin screwing-state height limiting plate are arranged on the lower end surface of the base plate; the rotating shaft passes through the base plate, and the eccentric pin height position guide rod is butted under the hook pin unscrewing-state height limiting plate; when the rotating shifting block is stirred and the eccentric hook pin is unscrewed, the eccentric pin height position guide rod is butted above the hook pin screwing-state height limiting plate. A car body can be stably fixed on the electrophoresis sledge by the eccentric locking pin. Whatever state the car body is adjusted to, the eccentric locking pin can keep a stable locking state.

Description

technical field [0001] The invention relates to the field of automobile electrophoresis skids, in particular to an eccentric pin used to hook the bottom hole of the automobile body to prevent the body from falling off the electrophoresis skid when the automobile body undergoes electrophoresis. Background technique [0002] In the automobile painting workshop, the posture of the body needs to be adjusted during electrophoresis in the electric pool. In order to prevent the body from falling off the transport carrier (such as a skid), a hook device is generally used to hook the bottom hole of the body. And existing decoupling generally adopts heavy hammer type rotation decoupling and eccentric rotation decoupling. The hammer-type undo pin has the disadvantages that the pin-in action occupies a large range, and its locking method by gravity is not safe; due to the penetration and adhesion of the electrophoretic fluid, it is difficult to maintain the locked state of the general e...

Problems solved by technology

The hammer-type undo pin has the disadvantages that the pin-in action occupies a large range, and its locking method by gravity is not safe; due to the penetration and adhesion of the electrophoretic fluid, it is difficult to maintain the locked state of the general eccentric rotating unpin, and it is difficult to ensure the height of the unpin before and after rotation.
