[0002] The potting jig that prevents glue from pouring into the motor is a supporting device for motor potting. When potting the motor, an axis is required in the inner diameter to prevent glue from entering the motor. Metal, Teflon and other materials are usually used as the axis. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of the potting jig that prevents glue from pouring into the motor.

[0003] The existing potting jig for preventing glue from being poured into the motor has certain disadvantages when used. First, after potting, due to the gap between the inner diameter of the motor and the inner diameter of the potting shaft, there is residual glue on the inner diameter, which interferes with the subsequent assembly of the motor. Post-processing is required to remove the residual glue, which is not conducive to people's use. In addition, the motor processing time is increased, which brings certain adverse effects to the actual use process. For this reason, we propose a potting jig for preventing glue from being poured into the motor. Utility Model Content
