[0026] Example 1

[0027] See also Figure 1-4 As shown, a motor mounting stand and a motor dynamometer test device include a motor body 4 and a mounting stand assembly 2;

[0028] The mounting frame assembly 2 includes a support plate 23, a fixing plate 29 is fixedly connected to the support plate 23 via a vertical plate 216, the motor body 4 is arranged above the fixing plate 29, and a limiting assembly is provided on the fixing plate 29, which limits the position of the motor body 4;

[0029] The limiting assembly includes a clamping plate 211, and the clamping plate 211 is provided with a pair and is symmetrically movable in the second mounting groove 214 on both sides of the fixed plate 29. A guide rod 218 is fixedly installed in the second mounting groove 214 on both sides along the length direction of the fixed plate 29. The guide rod 218 slides through the sliding hole opened in the middle of the clamping plate 211. The bottom end of the clamping plate 211 is slidably set in the groove 28 opened on the top of the support plate 23. A spring 219 is fixedly installed in the middle of the clamping plates 211 on both sides;

[0030] During operation, the motor body 4 is placed in from the inclined open ends of the top of the two side clamps 211, and the motor body 4 is supported by the fixing plate 29. The motor body 4 pushes the clamps 211 to move toward both sides, and the guide rod 218 and the groove 28 cooperate to make the clamps 211 move linearly toward both sides along the second mounting groove 214. At this time, the spring 219 is pulled up, and the rebound effect of the spring 219 pulls the clamps 211 on both sides to clamp on both sides of the motor body 4, so as to limit the motor body 4 in the horizontal direction; the spacing between the two side clamps 211 is adjustable, so that it is suitable for clamping motors of different sizes, and has a wider range of applications.

When the flexible belt 210 is pulled upward, the other end of the flexible belt 210 can pull the two side splints 211 to have a tendency to move toward the middle, so that the clamping force of the two side splints 211 is greater and the clamping effect is better; in addition, the flexible belt 210 provides downward pressure on the top of the motor body 4, thereby pressing the motor body 4 above the fixed plate 29 so as to limit the motor body 4 in the vertical direction, and finally the end of the flexible belt 210 is fixed to the movable rod four 225 by Velcro to prevent the flexible belt 210 from loosening, thereby stably limiting the motor body 4.
