Description

Technical Field

[0001] The utility model relates to the technical field of centerless grinders, and more specifically, to a grinding wheel replacement device for centerless grinders. Background Art

[0002] A centerless grinder is a type of grinder that does not require a workpiece to locate the axis. It is mainly composed of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece support. The grinding wheel actually performs the grinding work. This type of grinding wheel will gradually wear out due to long-term grinding and eventually reach a state where it cannot be repaired. In this case, the grinding wheel needs to be replaced, otherwise it will affect the processing quality of the workpiece.

[0003] At present, the replacement of grinding wheels still relies on manual operation, but the grinding wheels of centerless grinders are relatively heavy, so special attention should be paid to safety during installation. After the new grinding wheel is installed, it must be tested and adjusted twice for static balance or dynamic balance. Manual replacement of grinding wheels is prone to safety accidents, and it is time-consuming and labor-intensive, which is not conducive to the rapid resumption of production and reduces production efficiency.

[0004] Therefore, a grinding wheel replacement device for a centerless grinder is proposed to facilitate grinding wheel replacement and improve replacement efficiency. Utility Model Content
