[0038] During operation, the torque of the running motor is detected on the top of the detection platform 1. The motor 3 to be detected is placed on the top of the detection platform 1, and a card table 4 is fixed on the top of the detection platform 1 to support the card detector 2, and the detector 2 is used to realize the torque detection. In addition, a sliding card table 5 is fixed at the bottom of the motor 3 to be detected, and the sliding card table 5 can slide in the sliding card rail 7 on the top of the detection platform 1. When adjustment is needed, the two-way screw rod 8 is used to rotate and drive the sliding card table 5 to start sliding, thereby driving the motor 3 to be detected to move, so as to adjust the distance between the motor 3 to be detected and the detector 2, thereby realizing the effect of adjusting the axis length. After the adjustment of the spacing is completed, the sliding card table 5 is fixed to the top of the detection platform 1 by the limit bolt 9 to ensure that the motor to be detected is 3 can be in a stable state when working. At the same time, in order to adjust the load, the adjusting screw rod 10 is threadedly rotated on the surface of the load adjustment box 6. After the adjusting screw rod 10 is rotated, the locking block 11 is driven to move, thereby changing the clamping force on the elastic load sleeve 12.

When the load adjustment box 6 needs to be fixed in the appropriate position, the limit screw 16 is fixed in the limit slot 15, and the limit clamping platform 14 can slide on the surface of the limit screw 16. It is only necessary to rotate the limit nut 17 to both sides of the limit clamping platform 14 after the position of the load adjustment box 6 is adjusted, so as to fix the load adjustment box 6. In order to achieve the shaft length while ensuring that the load is always in the same position of the shaft, a transmission component is set, so that after the sliding clamping platform 5 moves, the limit clamping platform 14 can be driven to move together, thereby realizing the function of single adjustment of the shaft length. When performing such adjustment, the limit nuts need to be rotated from both sides of the limit clamping platform 14, so as to facilitate the limit clamping platform 14 to be able to move on the limit screw 16 The surface of the bearing slides, so that the transmission component can perform normal transmission functions. The function of adjusting the shaft length and the load is realized through the structural design of the adjustment component, so that the variable changes are detected separately, and then multiple groups of detection data are formed to ensure the accuracy of the detection results. The factors affecting the detection of motor torque are solved. It is related to the shaft length and the load. If the bearing and the load are not adjusted, the accuracy of the detection result cannot be guaranteed, which improves the efficiency of torque detection. In addition, an exhaust mesh 37 is opened on the surface of the load adjustment box 6, and then the built-in motor is used to drive the transmission gear 39 to start rotating, and then drive the large gear 40 to rotate.
