[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0031] like Figure 1-Figure 2 As shown, the present application provides a quick-release tool for testing a resolver, including a tool assembly 2, wherein the tool assembly 2 is used to fix and clamp the resolver 1, so that the resolver 1 can be factory tested on the tool assembly 2;

[0032] Meanwhile, the tooling assembly 2 includes a bottom plate 21, on which a plurality of mounting grooves 22 are formed, and screws can be installed inside the mounting grooves 22, so that the bottom plate 21 can be fixed to the external device by screws passing through the mounting grooves 22;

[0033] A workbench 23 is fixedly mounted on the bottom plate 21, and a rotating shaft 25 is mounted inside the workbench 23. It should be noted that the resolver 1 includes a stator (not shown), and the interior of the stator is hollowed out, so that the resolver 1 can be placed on the workbench 23, and the rotating shaft 25 can pass through the hollow position of the stator, so that the resolver 1 can be placed on the outer circle of the rotating shaft 25;

[0034] Two groups of limit blocks 24 are fixedly installed on the tooling table 23. It should be noted that three groups of fixed blocks 11 are fixedly installed at equal distances on the outer circle of the resolver 1. The end positions of the two groups of limit blocks 24 close to the fixed blocks 11 are respectively adapted to the outer circle of the fixed blocks 11. Therefore, when the resolver 1 is placed on the tooling table 23, two groups of fixed blocks 11 will be close to the end positions of the limit blocks 24, so that the resolver 1 can be positioned on the tooling table 23.

[0035] like Figure 2-Figure 3 As shown, a locking assembly is arranged on the bottom plate 21 near the tooling table 23, and the locking assembly includes a bottom block 26, and two groups of bolts 27 are installed inside the bottom block 26. At the same time, a threaded groove (not shown) adapted to the bolts 27 is opened on the bottom plate 21 near the tooling table 23, so that the locking assembly can be fixed to the bottom plate 21 through the bottom block 26 by the bolts 27, so that the locking assembly can be installed on the bottom plate 21;

[0036] At the same time, support blocks 28 are fixedly installed at both ends of the bottom block 26, and a bayonet 29 is rotatably connected inside the support block 28. At the same time, a clamping block 210 is fixedly installed on the outer circumference of the bayonet 29. The clamping block 210 is located between the two groups of bayonet pins 29, so that the clamping block 210 can rotate between the two groups of bayonet pins 29 through the support block 28;

[0037] A placement groove 211 is provided on the bottom block 26, a spring 212 is fixedly installed inside the placement groove 211, and the top of the spring 212 is fixedly connected to the bottom of the clamping block 210. The spring 212 is initially in an extended state, so that when the resolver 1 is placed on the workbench 23, the clamping block 210 can continue to approach one end of the fixed block 11 through the extension of the spring 212, and then can clamp the remaining fixed block 11, so that the fixed block 11 can be installed on the workbench 23;

[0038] At the same time, when the resolver 1 needs to be disassembled, the clamping block 210 can be pressed downward so that the clamping block 210 will gradually move away from the end of the resolver 1, so that the resolver 1 will lose its clamping effect, so that the resolver 1 can be quickly disassembled on the workbench 23.

[0039] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. 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.
