At the same time, some existing automated testing equipment has a complex structure and is difficult to adapt to motor casings of different specifications and shapes, and cannot meet the diverse production testing needs. Therefore, this utility model provides a motor casing hardness testing device. Utility Model Content

[0013] Beneficial effects

[0014] This invention provides a device for detecting the hardness of a motor housing. Compared with the prior art, it has the following advantages:

[0015] 1. This motor housing hardness testing device uses a positioning motor to drive a rotating plate. The rotation of the rotating plate causes one end of a transmission rod to rotate on top of the rotating plate, and the other end of the transmission rod to rotate on top of a transmission block. This causes the transmission block to slide on the surface of the limiting slide rail, and the sliding of the transmission block causes the positioning plate to slide synchronously, allowing the positioning plate to slide on the inner surface of the limiting groove. In this way, the motor housing is externally supported and fixed by four sets of positioning plates, thus maintaining the stability of the motor housing. By setting up a positioning mechanism, the position of the four sets of positioning plates can be synchronously adjusted by the positioning motor. The four sets of positioning plates can externally support and position motor housings of different sizes, thereby facilitating subsequent hardness testing of the motor housing and improving the applicability of the device.

[0016] 2. This motor housing hardness testing device uses a lifting cylinder to drive a piston rod, concave plate, testing cylinder, and hardness testing probe to slide downwards synchronously. This allows the concave plate to slide on the surface of a limiting rod, adjusting the height of the hardness testing probe. The testing cylinder then drives the piston rod and hardness testing probe to contact the motor housing, allowing the probe to test the hardness of the housing. After testing one area of ​​the motor housing, an adjusting motor drives an adjusting bevel gear to rotate. This rotation causes the rotating bevel gear, rotating shaft, support shaft, placement plate, and motor housing to rotate synchronously, adjusting the testing position of the motor housing. This enables comprehensive testing of the motor housing. The testing mechanism, driven by the lifting and testing cylinders, allows for flexible adjustment of the height and horizontal position of the hardness testing probe. Combined with the adjusting motor, this allows the positioned motor housing to rotate freely, achieving comprehensive and accurate hardness testing of the motor housing from all angles and at multiple locations.

The top of the rotating plate 314 slides the positioning plate 315 through the transmission assembly 4.

[0026] Adjustment component 32 is located inside the detection stage 1 and is used to drive the placement plate 312 to rotate.

[0027] The positioning motor 313 is a three-phase asynchronous motor and is connected to an external circuit via wires;

[0028] A display screen is installed on the rear left side of the top of the testing station 1.

[0029] In this embodiment, the transmission assembly 4 includes a transmission rod 41 rotatably mounted on the top of the rotating plate 314. One end of the transmission rod 41 is rotatably connected to a transmission block 42, and the top of the transmission block 42 is fixedly connected to the bottom end of the positioning plate 315.

[0030] In this embodiment, a limiting slide rail 5 is fixedly connected to the bottom of the inner cavity of the placement plate 312, and the surface of the limiting slide rail 5 is slidably connected to the inside of the transmission block 42.

[0031] The limiting slide rail 5 is used to limit the sliding movement of the transmission block 42.

[0032] In this embodiment, a limiting groove 6 is provided on the top of the placement plate 312, and the inner surface of the limiting groove 6 is slidably connected to the surface of the positioning plate 315.

[0033] The limiting groove 6 is used to slide and limit the positioning plate 315.

[0034] By setting up a positioning mechanism 3, the positions of the four sets of positioning plates 315 are synchronously adjusted by the positioning motor 313. The four sets of positioning plates 315 can be used to externally support and position motor housings of different sizes, which facilitates the subsequent hardness testing of the motor housing and improves the applicability of the device.

[0035] In this embodiment, the adjustment assembly 32 includes an adjustment motor 321 installed on the inner wall of the detection stage 1 and a rotating shaft 322 installed at the bottom of the support shaft 311. One end of the output shaft of the adjustment motor 321 is fixedly connected to an adjustment bevel gear 323 via a coupling. The surface of the rotating shaft 322 is rotatably connected to the bottom of the inner cavity of the detection stage 1. A rotating bevel gear 324 is fixedly connected to the surface of the rotating shaft 322. The surface of the rotating bevel gear 324 meshes with the surface of the adjustment bevel gear 323.

[0036] The regulating motor 321 is a three-phase asynchronous motor and is connected to an external circuit via wires.

[0037] In this embodiment, the testing mechanism 2 includes a testing seat 21 installed on the rear side of the top of the testing platform 1. A lifting cylinder 22 is fixedly connected to the top of the testing seat 21. A concave plate 23 is fixedly connected to the bottom of the lifting cylinder 22 through a piston rod. A limiting rod 24 is slidably connected inside the concave plate 23. The limiting rod 24 is installed inside the testing seat 21. A testing cylinder 25 is fixedly connected to the inner wall of the concave plate 23. A hardness testing probe 26 is fixedly connected to one side of the testing cylinder 25 through a piston rod.

[0038] The lifting cylinder 22 is connected to an external air source via an air pipe;

[0039] The detection cylinder 25 is connected to an external air source via an air pipe;

[0040] The limiting rod 24 is used to slide and limit the concave plate 23.

[0041] By setting up a detection mechanism 2, and using the combined drive of the lifting cylinder 22 and the detection cylinder 25, the height and horizontal position of the hardness detection probe 26 can be flexibly adjusted. With the help of the adjusting motor 321, the positioned motor housing can rotate flexibly, thereby realizing the hardness detection of the motor housing from all directions and in multiple positions, ensuring the comprehensiveness and accuracy of the detection results.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] During operation, the motor housing is first placed on top of the placement plate 312. Then, the positioning motor 313 is started, driving the rotating plate 314 to rotate. The rotation of the rotating plate 314 causes one end of the transmission rod 41 to rotate on top of the rotating plate 314, and the other end of the transmission rod 41 to rotate on top of the transmission block 42. This causes the transmission block 42 to slide on the surface of the limiting slide rail 5. The sliding of the transmission block 42 causes the positioning plate 315 to slide synchronously, allowing the positioning plate 315 to slide on the inner surface of the limiting groove 6. In this way, the four sets of positioning plates 315 provide external support and fixation for the motor housing, thus maintaining the stability of the motor housing. Subsequently, the lifting cylinder 22 is started, driving the piston rod, concave plate 23, detection cylinder 25, and... The hardness testing probe 26 slides downward synchronously, causing the concave plate 23 to slide on the surface of the limiting rod 24, thereby adjusting the height of the hardness testing probe 26. Then, by starting the testing cylinder 25, the piston rod and the hardness testing probe 26 are driven to fit against the motor housing, so that the hardness of the motor housing can be tested through the hardness testing probe 26. After the test of one part of the motor housing surface is completed, the adjusting motor 321 is started to drive the adjusting bevel gear 323 to rotate. The rotation of the adjusting bevel gear 323 will drive the rotating bevel gear 324, the rotating shaft 322, the support shaft 311, the placement plate 312 and the motor housing to rotate synchronously, thereby adjusting the testing position of the motor housing and realizing the comprehensive testing operation of the motor housing.
