The product positioning index plate 5 is provided with a groove matched with the index pin 6. The index pin 16 is driven by the index pin control cylinder 15 to realize the circumferential equal division positioning by cooperating with the groove. When the piston rod of the cylinder extends or retracts, the index pin will make corresponding reciprocating linear motion. The groove in the product positioning index plate 5 is designed and processed according to the predetermined circumferential equal division angle. The index pin cooperates with the groove in the product positioning index plate. When the product positioning index plate rotates to a specific angle, the index pin is inserted into the groove in the product positioning index plate under the action of the index pin control cylinder, realizing the circumferential equal division positioning. When it is needed to continue to rotate, the index pin is pulled out of the groove under the action of the cylinder, and the product positioning index plate can continue to rotate.
