Liftable locking and unlocking device for eccentric pin

Abstract

The invention relates to a liftable locking and unlocking device for an eccentric pin. The liftable locking and unlocking device for the eccentric pin comprises a bottom plate, a bottom frame, a guide wheel supporting mechanism, a lifting locking mechanism and a lifting driving mechanism, wherein the guide wheel supporting mechanism comprises a plurality of groups of guide wheel installation plates installed on the bottom frame and guide wheels installed on the guide wheel installation plates; the lifting locking mechanism comprises a lifting frame, the lifting frame is provided with a rail in the vertical direction, the rail is guided and located by the guide wheels, and a locking unit is arranged at the top of the lifting frame; and the lifting driving mechanism is installed on the bottom plate, the driving end of the lifting driving mechanism is connected with the lifting locking mechanism, the lifting driving mechanism drives the lifting locking mechanism to move up and down along the guide wheels. The problem that when a sleigh locking and unlocking station has space limitation, stretching and retracting of locking and unlocking cannot be realized through horizontal movement is solved, and the liftable locking and unlocking device for the eccentric pin is exquisite in structure, small in occupied space and stable in operation.

Description

technical field [0001] The invention belongs to the field of logistics transportation, and in particular relates to a lifting and lowering eccentric pin locking and unlocking device. Background technique [0002] At present, in the automobile painting workshop, the locking and unlocking devices of the eccentric pin on the electrophoretic skid are mostly arranged on both sides of the roller bed. The operation mode is that the motor drives the eccentric locking disc to perform locking and unlocking movement through the chain. In the direction of the skid, use the cylinder to push the motor and the locking disc fixing frame to perform telescopic movement to work. This arrangement takes up a lot of space in the direction perpendicular to the skid, and the working pressure of this method is in the same direction as the cylinder thrust, which increases the cylinder thrust requirement, increases the cylinder model, and the overall size becomes longer. In some cases, there are grea...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a lifting and lowering eccentric pin locking and unlocking device in order to solve the problems that the locking and unlocking of the eccentric pin of the existing electrophoretic skid takes up a lot of space and the type of the required cylinder is increased, which makes it difficult to meet the requirements.

The locking and unlocking device has a compact structure and a reasonable layout, which solves the problem of placing it in a limited space, improves the stress situation during work, and is convenient for installation and adjustment.
