How is the cam indexer positioned at high speed? Need to explain the positioning principle of the indexer.
The positioning of the cam indexer is completed by the rotation of the special structure of the cam on the input shaft of the indexer. Part of the structure of the input cam of the indexer is to split the needle roller bearing on the output turret. Pull the needle roller to make it rotate. Part of the structure is to perform rolling friction movement with the needle in a static state without pulling the needle.
In other words, the groove structure of the cam surface determines the operating state of the indexer. Regardless of the number of stations, as long as the driving angle is less than 360 degrees, the input cam will complete intermittent rotation.
From the perspective of the principle of indexer positioning, the positioning of the cam indexer during operation has nothing to do with the size of the speed. Controlling the indexer positioning needs to use a signal cam that is consistent with the driving angle of the indexer input cam, even in the case of high-speed operation, it is also signal The cam transmits the rotation state of the cam, combined with induction switches or proximity switches, to send signals to the control system (PLC) and other equipment, and then the system sends control instructions to the drive motor according to the cycle requirements of the operation, so it is not so much for the indexer Control is to control the motor used to drive the indexer. The indexer running at high speed generally has a smaller driving angle and faster rhythm. However, the realization of the intermittent function of moving and stopping is also determined by the input cam of the indexer.
