[0023] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments may be combined with each other. The following will describe this application in detail with reference to the drawings and in combination with the embodiments.

[0024] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this application.

[0025] As Figure 1 - Figure 2 shown, this application provides a resolver test fixture, which includes a vibration machine 1. At the same time, a placing component 2 is arranged on the vibration machine 1. The placing component 2 is used to place the resolver. At the same time, a clamping component 3 is arranged inside the placing box 23. The clamping component 3 is used to fix the resolver. At the same time, an auxiliary component 4 is arranged on the clamping component 3. The auxiliary component 4 is used to assist in fixing the protruding part of the resolver. Specifically:

[0026] As Figure 1 shown, the placing component 2 includes a placing box 23 arranged on the vibration machine 1 to facilitate placing the resolver. At the same time, multiple groups of cylinders 21 are fixedly installed on the vibration machine 1. At the same time, a push rod (not marked in the figure) is fixedly installed at the output end of the cylinder 21. At the same time, a hook 22 is hinged at the end of the push rod away from the cylinder 21. At the same time, a fixed rod (not marked in the figure) is fixedly installed on the vibration machine 1, and the end of the hook 22 away from the cylinder 21 is hinged on the fixed rod;

[0027] Driven by the cylinder 21, the push rod drives the hook 22 to rotate along the axis of the fixed rod, thereby driving the clamping block to fix the placing box 23 to facilitate the rapid replacement of the placing box 23;

[0028] As Figure 1 - Figure 3 shown, the clamping assembly 3 includes multiple groups of bases 31 fixedly installed on the placement box 23. At the same time, multiple groups of mounting boxes 32 are fixedly installed on the bases 31, and a motor 34 is fixedly installed inside the mounting box 32. The output end of the motor 34 is fixedly installed with a lead screw 35. The lead screw 35 is rotatably installed inside the base 31. At the same time, multiple groups of chutes are opened on the base 31. A slider 36 is slidably arranged inside the chute, and a support block 33 is fixedly installed on the slider 36. At the same time, the slider 36 is threadedly installed on the lead screw 35;

[0029] When it is necessary to fix the resolver, it is sleeved on multiple groups of support blocks 33. Driven by multiple groups of motors 34, the lead screw 35 drives the slider 36 to move. At the same time, the slider 36 synchronously drives the support block 33 to move, and through the setting of the chute, its moving direction is fixed, so that multiple groups of support blocks 33 outwardly support the resolver to fix the resolver;

[0030] As Figure 2 - Figure 3 shown, the auxiliary assembly 4 includes a groove 42 opened on the base 31. A moving block 44 is slidably arranged inside the groove 42. At the same time, a cushion block 45 is fixedly installed on the moving block 44. At the same time, a screw rod 43 is rotatably installed inside the groove 42. At the same time, a knob 41 is fixedly installed at one end of the screw rod 43, and the moving block 44 is rotatably installed on the screw rod 43. It should be noted that rubber pads (not marked in the figure) are provided on both the cushion block 45 and multiple groups of support blocks 33 to prevent the resolver from being damaged due to excessive supporting force;

[0031] After the clamping assembly 3 fixes the resolver, rotate the knob 41. The screw rod 43 drives the moving block 44 to move along the axis direction of the screw rod 43 inside the groove 42, so as to synchronously drive the cushion block 45 to move until the cushion block 45 abuts against the resolver to assist in fixing its protruding part, and the position of the cushion block 45 can be adjusted according to the different sizes of the resolver;

[0032] In summary, when clamping the resolver, the placement box 23 is fixed by the placement assembly 2, and then the resolver is sleeved on the clamping assembly 3. At this time, the clamping assembly 3 is started to fix it by internal support. Subsequently, through the auxiliary assembly 4, the protruding part of the resolver is assisted in fixing, and then it can be tested by the vibrator 1.

[0033] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
