Description

Technical Field

[0001] The utility model relates to the technical field of synchronous belt wheel processing, in particular to a deburring device for synchronous belt wheel processing. Background Art

[0002] Synchronous belt drive is composed of a closed ring belt with equally spaced teeth on the inner surface and a corresponding pulley. When in motion, the belt teeth mesh with the tooth grooves of the pulley to transmit motion and power. It is a meshing drive, and thus has the characteristics of gear drive, chain drive and flat belt drive. It is widely used in the fields of automobiles, textiles, various precision machine tools, etc.

[0003] The prior art requires polishing and grinding when processing a synchronous pulley, but the existing device lacks an effective fixing method when polishing and grinding the inner hole of the pulley. In addition, since the outer side of the pulley is a circular structure, the pulley workpiece will rotate relative to the workpiece under the friction force of the polishing head during grinding, thereby affecting the polishing effect. For this reason, we propose a deburring device for synchronous pulley processing. Utility Model Content
