Analyze the reasons for the inaccurate positioning of the cam indexer

Inaccurate positioning of the cam indexer is a relatively common problem. When a problem often occurs, we need to find the cause so that we can solve it.

Inaccurate positioning of the cam indexer means that the specified position accuracy difference is too large. Generally speaking, as long as the workpiece with mechanical structure has a certain error value, it is normal as long as it is reasonable, but if it is too large, it will affect the processing, so First of all, it is necessary to determine whether the positioning is normal.

In the actual repair, first check whether the positioning error is the output shaft up-down error or the left-right error. You can check the following steps in the device.

1. Lock the disc on the output shaft tightly and check whether the positioning error is caused by the looseness.

2. Check whether the error between the stations on the disc is too large.

3. Check whether the bearing of the input shaft is worn or not, and whether the oil seal of the input shaft is damaged.

4. Check whether the torque of the input motor is normal, and whether it is sometimes large and sometimes small.
