[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] See also Figure 1-4 A torque detection device for a brush spring includes a main body module 100 and a detection module 200. The main body module 100 includes two support plates 110, and a connecting rod 120 is fixedly connected between the two support plates 110. The detection module 200 is arranged between the two support plates 110. The detection module 200 includes a protective component 210 arranged between the tops of the two support plates 110, and a detection component 220 is also arranged between the two support plates 110. A driving component 230 is provided on one of the support plates 110, and the driving component 230 is connected to the detection component 220.

[0038] By setting the protection component 210, the spring can be prevented from breaking and causing danger to the staff during work. By setting the detection component 220, the spring can be tested for torque. By setting the driving component 230, the detection component 220 can be driven to move its position, which is convenient for torque testing of springs of different lengths.

[0039] The protective assembly 210 includes two groups of fixed blocks 211 respectively fixedly connected to the two ends of the two support plates 110, and the two groups of fixed blocks 211 are fixedly connected to fixed bars 212. The protective assembly 210 also includes a protective frame 213 slidably connected between the tops of the two fixed bars 212, and the protective frame 213 is provided with tempered glass 214. The protective assembly 210 also includes two sliding grooves 215 respectively opened at the tops of the two fixed bars 212, and the interiors of the two sliding grooves 215 are slidably connected to sliding bars 216, and the tops of the two sliding bars 216 are fixedly connected to the bottom of the protective frame 213.

[0040] By sliding the protective frame 213 between the tops of the two fixed bars 212, the sliding bar 216 can be slidably connected to the inner side of the slide groove 215, so that the protective frame 213 and the tempered glass 214 can be installed. By pushing the protective frame 213 to move, the sliding bar 216 can slide inside the slide groove 215, so that the position of the protective frame 213 and the tempered glass 214 can be adjusted, and then the position of the protective frame 213 and the tempered glass 214 can be adjusted according to the length of the spring, thereby improving practicality.

[0041] The detection assembly 220 includes a fixed rod 221 fixedly connected between the upper portions of the two support plates 110, a first mounting block 222 fixedly connected between the surfaces of the two fixed rods 221, and a second mounting block 223 slidably connected between the surfaces of the two fixed rods 221. The detection assembly 220 also includes a support block 224 fixedly connected to one side of the second mounting block 223, a stepper motor 225 fixedly connected to the top of the support block 224, and an output end of the stepper motor 225 extends to the other side of the second mounting block 223. The detection assembly 220 also includes a fixed connection to the output end of the stepper motor 225. A first hook 226 at the output end, a second hook 227 is fixedly connected to one side of the first mounting block 222, a spring body 228 is arranged between the second hook 227 and the first hook 226, the driving assembly 230 includes a mounting frame 231 fixedly connected to one side of one of the support plates 110, a hydraulic cylinder 232 is fixedly connected to the interior of the mounting frame 231, and the output end of the hydraulic cylinder 232 extends to the other side of one of the support plates 110, the output end of the hydraulic cylinder 232 is fixedly connected to a rectangular block 233, and the top of the rectangular block 233 is fixedly connected to the bottom of the second mounting block 223.

[0042] By starting the stepper motor 225, the stepper motor 225 will gradually drive the first hook 226 to twist the spring body 228, so that the torque of the spring body 228 can be detected. By starting the hydraulic cylinder 232, the second mounting block 223 can be driven by the rectangular block 233 to slide and adjust the position on the surface of the two fixed rods 221, so that it can be used with springs of different lengths, thereby improving practicality.

[0043] The implementation principle of the embodiment of the present application is as follows: when work needs to be carried out, the hydraulic cylinder 232 is first activated according to the length of the spring body 228 to be tested. The hydraulic cylinder 232 drives the second mounting block 223 to slide on the surface of the two fixed rods 221, thereby adjusting the distance between the first mounting block 222 and the second mounting block 223. Then, the spring body 228 to be tested is connected between the first hook 226 and the second hook 227. At this time, in order to ensure the safety of the staff, it is necessary to slide the protective frame 213 between the tops of the two fixed bars 212 so that the two sliding bars 216 can be slidably connected to the inner sides of the two sliding grooves 215 so that the protective frame 213 can be located outside the spring body 228, thereby protecting the staff. At this time, the stepper motor 225 is started, and the stepper motor 225 drives the first hook 226 to rotate, thereby driving the spring body 228 to rotate, thereby realizing the torque detection of the spring body 228. The staff can clearly observe the entire detection process through the tempered glass 214, thereby improving practicality.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
