Description

Fixing device for clamping synchronous belt die Technical Field The utility model relates to a synchronous belt die fixing device, in particular to a fixing device for clamping a synchronous belt die. Background Generally, synchronous belts are widely used for power transmission of equipment. The synchronous belt has the characteristics of accurate transmission and stable transmission. The synchronous belt has no sliding during working and constant transmission ratio. The inner periphery of the synchronous belt is toothed. In the production of the synchronous belt, a synchronous belt mold is required. The outer surface of the synchronous belt die is processed into a tooth shape. The quality of the tooth processed on the synchronous belt die directly influences the quality of the synchronous belt. When the synchronous belt die is subjected to hobbing, the synchronous belt die is difficult to fix. How to solve this problem becomes important. The existing scheme generally adopts the clamp to clamp the shaft part of the synchronous belt die, and when the synchronous belt die is machined to form teeth, the force applied to the synchronous belt die is large, and the deformation of the shaft part is easy to cause. Affecting the accuracy of the timing belt mold.
