The position control telescoping torque arms help manufacturers detect and eliminate costly screw-fastening errors during the assembly process. Position Control telescoping torque arms are designed to reduce the risk of improperly fastened screws, ensuring that every screw is in the correctly tightened in the correct sequence. Using the EZ-Glider Position Control torque arm is like putting the eyes and ears of a quality control manager where they are needed most - right on the assembly area. The EZ-Glider Position Control telescoping torque arm consists of a torque reaction arm with encoders mounted at the base and a control box. The control box is used for programming and it tracks the axis movement by converting angle counts to the precise position of the screwdriver. The location is calculated from encoder values, allowing the operator to easily teach the torque arm a programmed sequence pattern and then use it to control the assembly process.
