Description

Technical Field

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

[0002] Synchronous pulleys are generally made of steel, aluminum alloy, cast iron, brass and other materials, and their inner holes are round holes, D-shaped holes, tapered holes, etc. During the processing of synchronous pulleys, cutting equipment is used to cut the edges of the synchronous wheels, thereby forming a tooth groove structure around the synchronous wheel. After cutting, burrs will inevitably appear on its surface, so it is necessary to polish and deburr the tooth groove area.

[0003] For example, the patent publication number CN214721147U is a fixing device for deburring a synchronous pulley, which includes a base, a fixing block, a connecting block and an electric telescopic rod. A first fixing box is arranged on the upper side of the base, and a servo motor is arranged inside the first fixing box. The fixing block is arranged on the side of the storage plate. The fixing device for deburring a synchronous pulley is provided with two groups of connecting blocks and two groups of latching teeth. When the deburring device is used to deburr the synchronous pulley, the synchronous pulley is placed on the storage plate. At this time, the external threaded rod is rotated so that the connecting block drives the latching teeth to engage with the outer surface of the synchronous pulley, so that the synchronous pulley is limited, thereby making the synchronous pulley more stable during deburring.

[0004] In actual use, the deburring fixing device proposed in the above patent document uses two sets of clamping teeth to clamp and fix the side tooth block area of ​​the synchronous belt pulley. The clamping teeth will block the synchronous wheel tooth block area that needs to be polished, resulting in the polishing equipment being unable to fully and completely polish the synchronous wheel. The synchronous wheel position needs to be adjusted and then a second polishing is performed, which reduces the efficiency of the polishing process. Utility Model Content
