[0002] Frameless torque motors are a new type of motor that has emerged in recent years with the development of robotics, precision manufacturing, and automated equipment. Traditional motors typically employ a closed structure, encapsulating core components such as the stator and rotor within a metal casing. Frameless torque motors, however, eliminate this casing, retaining only the stator and rotor core components, which are directly integrated into the mechanical structure of the equipment. Frameless torque motor performance testing fixtures are comprehensive testing platforms specifically designed for frameless motors. These fixtures are not only used for performance optimization during the motor development stage but are also widely applied in production quality inspection and fault diagnosis, providing core assurance for the quality control of frameless torque motors.

This not only makes testing cumbersome but also necessitates determining the dimensions of the frameless motor, and prevents installation and testing if the corresponding fixture is unavailable. To address these issues, this invention provides a frameless torque motor performance testing fixture. Utility Model Content

[0021] This utility model discloses a frameless torque motor performance testing fixture.

[0022] Example 1

[0023] According to the appendix Figure 1-4 As shown, the device includes a stator clamping component 1, which clamps the stator. One end of the stator clamping component 1 is fixedly connected to a rotor support assembly 3. The rotor support assembly 3 includes an adjusting bolt 31, a fixed housing 33, and support triangular blocks 34. The adjusting bolt 31 is threaded to one end of the fixed housing 33. A limit rod 332 is fixedly connected to the inner wall of the fixed housing 33. The fixed housing 33 is located at the axis of the rotor. The support triangular blocks 34 are slidably connected to the limit rod 332. Four sets of support triangular blocks 34 are arranged in an array within the fixed housing 33. The adjusting bolt 31 is used to adjust the outward sliding distance of the support triangular blocks 34. A connecting slider 341 is fixedly connected to the back end of the support triangular blocks 34. A spring 342 is also provided on the supporting triangular block 34, which is slidably connected to the limiting rod 332. One end of the spring 342 is fixedly connected to the connecting slider 341, and the other end of the spring 342 is fixedly connected to the fixed housing 33. The spring 342 is used to slide the supporting triangular block 34 back into the fixed housing 33. A friction rubber pad 343 is fixedly connected to the outer end of the supporting triangular block 34. The friction rubber pad 343 presses against the inner wall of the rotor. A long sliding groove 331 is opened in the fixed housing 33. The supporting triangular block 34 is slidably connected in the long sliding groove 331. One end of the adjusting bolt 31 is fixedly connected to a sliding pressing rod 311. The sliding pressing rod 311 is slidably connected in the fixed housing 33. The sliding pressing rod 311 is used to press the supporting triangular block 34 outward.

[0024] In use, the fixed housing 33 is placed inside the rotor, and the adjusting bolt 31 is rotated to slide the sliding extrusion rod 311 into the fixed housing 33. This causes the four sets of supporting triangular blocks 34 to support the long slide groove 331 under extrusion until the four sets of supporting triangular blocks 34 abut against the inner wall of the rotor and are tightly abutted, thus completing the adjustment of the rotor's support shaft. After the test is completed, the adjusting bolt 31 is rotated to slide the sliding extrusion rod 311 outward, and the supporting triangular blocks 34 return to their original positions under the pull of the spring 342.

[0027] The stator clamping component 1 includes a fixed main clamping block 11 and a movable secondary clamping block 12. The movable secondary clamping block 12 is fixedly connected to one end of the fixed main clamping block 11.
