Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheels, and more specifically, to a concentricity correction device for the inner circles of multiple grinding wheels. Background Art

[0002] A grinding wheel, also known as a vitrified abrasive tool, is a vitrified abrasive tool in which ordinary abrasives are solidified into a certain shape (mostly circular with a through hole in the center) by a binder and has a certain strength. It generally consists of abrasives, a binder, and pores, and these three parts are often referred to as the three elements of a vitrified abrasive tool. According to different classifications of binders, common ones include ceramic (binder) grinding wheels, resin (binder) grinding wheels, and rubber (binder) grinding wheels.

[0003] Some patent documents with grinding wheel correction devices are disclosed in the prior art. The Chinese patent with the application number CN202223437080.6 discloses a grinding wheel balance detection and correction device, which is characterized in that it includes a grinding wheel bracket, a grinding wheel base, and a gasket. The grinding wheel bracket is sleeved on the grinding wheel base. A support column is fixed in the middle of the grinding wheel base. A concentric cavity that cooperates with the support column is provided in the middle of the bottom of the grinding wheel bracket. The shape of the cavity is adapted to the shape of the support column. The vertex of the cavity abuts against the vertex of the support column. A gap for the grinding wheel bracket to tilt when the grinding wheel is unbalanced is left between the cavity and the support column; the gasket is arranged on the surface of the grinding wheel, and a default part is provided at its eccentric position, and the default part is in the same direction as the center of gravity offset direction of the grinding wheel. The utility model uses the cooperation of the grinding wheel base and the grinding wheel bracket to detect the balance of the grinding wheel, and the gasket is used to correct the unbalanced grinding wheel to make the unbalanced grinding wheel balanced. The structure of the utility model is simple, and it can quickly and accurately detect the balance of the grinding wheel and correct it.

[0004] In the above patent, it is difficult to make multiple grinding wheels concentric at the same time, which affects the processing convenience. For this reason, we propose a concentricity correction device for the inner circles of multiple grinding wheels. Content of the Utility Model

The rotation of the bidirectional lead screw 10 causes the two nuts 12 to move inward or outward simultaneously on the surface of the bidirectional lead screw 10. The movement of the nuts 12 drives the sliding seats 13 to move. When the bidirectional lead screw 10 rotates forward, the two nuts 12 move inward simultaneously. The movement of the nuts 12 drives the sliding seats 13 and the sliding plates 14 to move inward. When the two sliding plates 14 move inward, they drive the four shifting rods 15 to move inward simultaneously. The multi-piece grinding wheels are clamped by the four shifting rods 15. The clamping by the four shifting rods 15 facilitates the positioning of the multi-piece grinding wheels, thereby facilitating the concentricity of the multi-piece grinding wheels.
