[0005] However, if the three clutch teeth of the existing traditional hydraulic indexing plate want to speed up the rotation, when the oil pressure is adjusted to more than 35KG, the teeth will break, and there will be problems such as back and forth movement and tooth breakage. Summary of the invention

[0006] In view of the above situation, in order to solve the problems existing in the above technology, the present invention proposes a five-piece clutch gear indexing plate, which has a more precise structure and stronger rigidity, and at the same time solves the back-and-forth movement and tooth breakage problems of traditional hydraulic indexing plates.

[0012] According to a five-clutch gear indexing plate of the present application, the transmission teeth arranged on the outer circle of the second data clutch teeth are meshed with the transmission rack.

[0013] After adopting the technology proposed by the present invention, the five-clutch gear indexing plate according to the embodiment of the present invention has the following beneficial effects.

[0014] 1) Due to the matching of the tooth row components with the large and small data clutch teeth, and by matching the rotating components with the large and small data clutch teeth, more accurate finishing is achieved during locking processing, which greatly improves the back-and-forth movement and tooth breakage phenomena when the traditional data teeth are rotated into place and locked.
