Description

A new flip device

Technical Field

The utility model relates to the technical field of abrasive tool production, in particular to a novel turning device.

Background Art

Abrasives and grinding tools are widely used in mechanical processing and are usually used for grinding parts to meet certain technical requirements. The most widely used ones are cutting discs, grinding wheels and shutter blades.

During production, the mold itself is usually clamped by a corresponding clamping mechanism and then processed accordingly. However, since both the upper and lower surfaces of the mold usually need to be processed, the simple clamping mechanism requires manual removal of the grinding disc, flipping it over, and then clamping it during the processing, resulting in relatively low production efficiency.

The stepping motor is fixedly mounted on the left and right outer sides of the mounting ring, and a driving shaft is fixed on the output end thereof. A middle clamping mechanism is arranged between the left and right driving shafts, and the grinding disc is clamped by the clamping mechanism. The mounting ring serves as a basic unit of a tooling for placing and clamping the grinding disc, and is connected by a bracket and a bolt pressure plate. The middle clamping mechanism is placed on the workbench at a certain height so as not to affect the turning of the middle clamping mechanism when the stepper motor is started. A threaded groove is opened at the top of the middle clamping mechanism, and the stud is installed in cooperation with the threaded groove. The top of the middle clamping mechanism is fixed with a cover plate, and a clamping part is arranged on it to further clamp the clamped grinding disc to maintain stable processing.
