Description

Intelligent pivot assembly system and method

The invention relates to an intelligent assembly system, in particular to a system and method for locking a nut to a pivot.

Most of the pivot assembly process is completed after each step, and each step after the process is expanded requires an operator to operate, which not only consumes manpower but also increases man-hours. Taking a pivot with a single-axis rotating shaft group as an example, the nut locking step in the assembly pivot manufacturing process is to lock the nut to the pivot to stop the elastic member that provides elastic force, so as to obtain the finished pivot. In the subsequent torque test step, if the torsion of the pivot product is not within the specification value after the test, the pivot product must be returned to the nut locking step for adjustment and then re-enter the torque test step. In addition, the traditional torque test procedure relies on manual inspection with a torque wrench. Not only is the test efficiency low, but the accuracy rate is not high. The level cannot be guaranteed during manual testing. There are lateral forces that affect the test results, and the reliability is not high or impossible. Real-time recording of the torque value during the test is not suitable for mass production. Therefore, the current pivot assembly process still has a lot of room for improvement.
