[0002] In the manufacturing process of electric motors, the hardness of the motor housing is one of the important indicators for measuring its quality and performance. Appropriate hardness can ensure that the motor housing has sufficient strength and stability during use, effectively resist external impacts and wear, and extend the service life of the motor.

[0003] However, existing motor housing hardness testing devices have certain limitations. On the one hand, existing fixing devices cannot achieve fast, stable and accurate fixing for motor housings of different lengths and sizes, which makes the motor housing prone to shaking during the testing process and affects the accuracy of the test results. On the other hand, existing testing devices often can only test a part of the motor housing during testing, and cannot achieve comprehensive testing of the entire housing surface, which cannot fully reflect the actual hardness of the motor housing, making the test results somewhat biased.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0023] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1 to 4 This application provides a motor housing hardness testing device, including a base plate 1, a fixing component 2 on the top of the base plate 1, and a testing component 3 on the outside of the fixing component 2. The fixing component 2 includes a turntable 21, a sliding groove 28 is opened inside the turntable 21, a sliding rod 29 is fixedly installed inside the sliding groove 28, a slider 210 is slidably connected to the outside of the sliding rod 29 and inside the sliding groove 28, a fixing rod 215 is fixedly installed on the inner end of the slider 210, a motor housing 4 is sleeved between the outside of the fixing rod 215, a support ring 22 is rotatably connected to the outside of the turntable 21, a support plate 23 is fixedly installed at the bottom of the support ring 22, a moving block 24 is fixedly installed at the bottom of the support plate 23, and the moving block 24 is slidably connected to the top of the base plate 1.

[0025] A side plate 25 is fixedly installed on the top of the base plate 1. A first screw 26 is rotatably connected between the two side plates 25. The first screw 26 is screwed through two moving blocks 24. The threads on both sides of the center of the first screw 26 have different directions of rotation. The two moving blocks 24 are respectively screwed to the outer sides of the threads with different directions of rotation of the first screw 26. A first motor 27 is fixedly installed on the outer end of the side plate 25. The output end of the first motor 27 movably passes through the interior of the side plate 25 and is fixedly connected to the first screw 26. A second screw 213 is rotatably connected to the outer side of the turntable 21. An adjusting block 212 is screwed to the outer side of the second screw 213. A connecting rod 211 is hinged between the adjusting block 212 and the corresponding slider 210. A knob 214 is fixedly installed on the outer end of the second screw 213.

[0026] In this embodiment, when performing hardness testing on the motor housing 4, the motor housing 4 is first fixed. During fixing, the motor housing 4 is placed between two turntables 21. The first motor 27 is started to drive the first screw 26 to rotate. The first screw 26 drives the moving blocks 24 on both sides to move synchronously in opposite directions. The movement of the moving blocks 24 drives the upper support plate 23, support ring 22, and turntables 21 to move synchronously in opposite directions. The two sides of the turntables 21 are then attached to the two sides of the motor housing 4. Finally, the second screw is driven by rotating the knob 214. Rotation of screw 213 causes adjustment block 212 to move. The movement of adjustment block 212, in conjunction with connecting rod 211, causes slider 210 to move along slide rod 29 and slide groove 28. Slider 210 causes fixed rod 215 to move outward. Fixed rod 215 moves outward and fits against the inner wall of motor housing 4, thus securing the outer side of motor housing 4. The fixed rod 215, which can move inward and outward, and the turntable 21, which can move left and right, achieve the effect of fixing motor housing 4 of different lengths and sizes.

[0027] Reference Figures 1 to 4 In one aspect of this embodiment, the detection component 3 includes a bracket 34, which is fixedly installed on the top of the base plate 1. A top plate 35 is fixedly installed on the top of the bracket 34. An electric slide rail 38 is fixedly installed on the bottom of the top plate 35. A track slider 39 is slidably connected inside the electric slide rail 38. A hydraulic rod 36 is fixedly installed on the bottom of the track slider 39. A detection head 37 is fixedly installed at the output end of the hydraulic rod 36.

[0028] A gear ring 31 is fixedly installed on the outer side of the right turntable 21, and a second motor 32 is fixedly installed on the top of the right moving block 24. A gear 33 is fixedly installed on the output end of the second motor 32. The gear 33 meshes with the gear ring 31. The second motor 32 is a self-locking motor.

[0029] In this embodiment, after the motor housing 4 is fixed, the hydraulic rod 36 drives the detection head 37 to adhere to the surface of the motor housing 4 for testing. The detection head 37 is a Rockwell hardness tester probe. The electric slide rail 38 is activated to drive the track slider 39 to move. The movement of the track slider 39 drives the detection head 37 to move left and right, thereby achieving left and right adjustment of the detection position. Furthermore, the second motor 32 is activated to drive the gear 33 to rotate. The rotation of the gear 33 drives the gear ring 31 to rotate. The rotation of the gear ring 31 drives the right turntable 21 to rotate. The rotation of the turntable 21 drives the inner motor housing 4 to rotate. By rotating the motor housing 4, hardness testing can be performed on all circumferences of the housing 4, thus ensuring comprehensive testing.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] Working principle:

[0032] Fixing the motor housing: Place the motor housing 4 between the two turntables 21, start the first motor 27, and its output end drives the first screw 26 to rotate. Since the threads on both sides of the center of the first screw 26 have different directions of rotation, and the two moving blocks 24 are respectively screwed to the outside of the threads with different directions of rotation of the first screw 26, the rotation of the first screw 26 will drive the moving blocks 24 on both sides to move synchronously in opposite directions. The movement of the moving blocks 24 will drive the upper support plate 23, support ring 22 and turntable 21 to move synchronously in opposite directions, so that the two sides of the turntable 21 are in contact with the two sides of the motor housing 4. Then rotate the knob 214, which drives the second screw 213 to rotate. The rotation of the second screw 213 drives the adjusting block 212 to move. The movement of the adjusting block 212, together with the connecting rod 211, drives the slider 210 to move along the sliding rod 29 and the sliding groove 28. The slider 210 drives the fixing rod 215 to move outward. The fixing rod 215 moves outward and is in contact with the inner wall of the motor housing 4, thus fixing the motor housing 4.

[0033] Hardness Testing: After the motor housing 4 is fixed, the hydraulic rod 36 drives the testing head 37 to fit against the surface of the motor housing 4. The testing head 37 is a Rockwell hardness tester probe, which can perform hardness testing on the motor housing 4. The electric slide rail 38 is activated, and the track slider 39 inside the electric slide rail 38 moves under the drive of the electric slide rail 38. The movement of the track slider 39 drives the testing head 37 to move left and right, realizing the left and right adjustment of the testing position. At the same time, the second motor 32 is activated. The output end of the second motor 32 drives the gear 33 to rotate. The gear 33 meshes with the gear ring 31, so the rotation of the gear 33 drives the gear ring 31 to rotate. The rotation of the gear ring 31 drives the right turntable 21 to rotate. The rotation of the turntable 21 drives the inner motor housing 4 to rotate, realizing the hardness testing of one circle of the motor housing 4.
