Recently, there is a question about how to use a motor to control the driving angle of a
cam indexer. The question is a bit vague, but it can be reviewed from two aspects.
First of all, the driving angle of the indexer of the cam indexer is fixed. For the indexer with intermittent motion and stop, the motor cannot control the driving angle. The structure of the input cam of the indexer is fixed. During transmission, the angle of repose is at In the self-locking state, and the driving angle must be consistent with the actual automatic station moving and stopping position during the process of dividing, otherwise, the uniform time and station function of the turntable will not be realized. In actual use, the way to realize the motor control should be completed by the induction system matched with the indexer. The rotation state of the signal cam and the input shaft of the indexer is consistent, and the signal is transmitted to the motor through the photoelectric switch, and the movement and stop of the indexer are controlled by the movement and stop of the motor.
Really relying on the motor to control the drive is for the 360-degree drive angle of the indexer. Most of the servo or stepper motors are used. In this case, the indexer essentially becomes a high-level reducer, servo Both the motor and the stepper motor rely on pulses to achieve movement and stop, which is also its unique function. In a single system, the servo and stepper drive can complete the control of the indexer.
However, when the driving angle is less than 360 degrees, the servo or stepping will not affect the operation of the indexer, because the structure of the indexer determines that its accuracy and movement stop are not affected by any
driving equipment. This is What we said, in the use of the indexer, as long as the ordinary gear reducer motor can fully meet the requirements of use.
