Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated.

As shown in fig. 1, the utility model provides a pair of motor detection frock, especially a short-term test frock for frameless torque motor mainly includes: stator jacket 1, rotor shaft 2, supporting seat 3, stator dismounting part 4, output shaft 5, base plate 6.

As shown in fig. 2, the stator holder 1 has a hollow ring structure and is divided into two parts, namely a fixed end 11 and a clamping end 12. The fixed end 11 and the clamping end 12 are fixedly connected into a whole by partial ring sections, and gaps exist in the other partial ring sections. The fixed end 11 is of an integral ring structure, and threaded holes are formed in the circumferential direction of the ring structure and used for fixedly mounting the stator jacket 1 on the supporting seat 3. The holding end 12 is an open ring structure, a radial groove is formed at the opening of the ring, and a screw connecting structure is arranged in the groove. A step is provided on the inner wall of the ring of the clamping end 12 for positioning. The motor stator 7 is mounted to the clamping end 12 of the stator jacket 1 and is positioned by a step of the clamping end 12. After the motor stator 7 is installed in place, the inner diameter of the split ring is reduced through the screw connection structure of the radial groove of the clamping end 12, the motor stator 7 is clamped, and at the moment, the motor stator 7 is in a locking state.

As shown in fig. 1, one end of the rotor shaft 2 is provided with a bearing mounting surface and fixedly mounted with the support base 3 through a bearing, and the other end is provided with a concave mounting surface and fixedly mounted with the motor rotor 8. One end of the rotor shaft 2 connected with the supporting seat is also fixedly connected with an output shaft 5.
