[0028] like Figures 1 to 3 As shown, this embodiment provides a convenient multi-functional motor fault detection device, including an assembly base plate 100. A motor mounting base 110 is provided on the upper end of the assembly base plate 100 (the assembly base plate 100 and the motor mounting base 110 are the mounting structures for the motor 200 under test). A detection motor 200 is detachably mounted on the upper end of the motor mounting base 110. A rotating shaft 210 is provided on one side of the detection motor 200. A fixed base plate 300 is detachably mounted on the upper end of the assembly base plate 100. A support base 600 is movably mounted on the upper end of the fixed base plate 300. A positioning ring is provided on the upper end of the support base 600. A positioning ring is sleeved on the surface of the rotating shaft 210. A detection cylinder 400 is fixedly installed on one side of the positioning ring. The detection cylinder 400 is sleeved on the surface of the rotating shaft 210. A detection structure is provided inside the detection cylinder 400. The detection structure includes four detection grooves 410, which are respectively opened on both sides of the inner wall of the detection cylinder 400. The length of the detection cylinder 400 is less than the length of the rotating shaft 210. Distance sensors 411 are provided at both ends of the inner wall of the detection groove 410. A speed sensor 412 is provided in the middle of the inside of the detection groove 410. The speed sensor 412 is located between the two distance sensors 411.

[0029] In this embodiment, for motors already installed at the point of use, the user does not need to remove the motor 200 to be tested from the mounting base plate 100 and the motor mounting seat 110. The positioning ring and the detection cylinder 400 are sleeved on the motor shaft 210. Under the action of the positioning structure, the positioning ring and the detection cylinder can be positioned at the same center as the shaft 210. Under the action of the fixed base, the positioning ring and the detection cylinder can be supported. When the motor 200 is running, the distance sensor 411 can detect the rotation of the shaft 210 and observe whether there is a deflection phenomenon of the shaft 210. Through the setting of the speed sensor 412, the speed of the shaft 210 can be detected. An information transmission module can be set inside the device to connect with the detection cylinder 400 via Bluetooth or other means to observe the monitoring structure.

[0030] like Figures 2 to 4 As shown, this embodiment provides a convenient multi-functional motor fault detection device. Movable holes are provided on both sides of the upper end of the fixed base plate 300. Rotating screw sleeves 310 are rotatably installed on both sides of the upper end of the fixed base plate 300. A transmission sprocket and transmission chain are connected between the two rotating screw sleeves 310. The rotating screw sleeves 310 are connected to the movable holes. A rotating block is provided on the outer surface of the rotating screw sleeve 310. A lifting screw 311 passes through the interior of the rotating screw sleeve 310. The upper end of the lifting screw 311 is fixedly connected to the support base 600, and the lower end of the lifting screw 311 extends into the interior of the movable hole. Grooves are provided on both sides of the lower end of the fixed base plate 300. Adsorption suction cups 320 are provided inside the grooves, and the adsorption suction cups 320 are adsorbed onto the assembly base plate 100.

[0031] In this embodiment, after the positioning seat 500 and the detection cylinder 400 are positioned at the same center as the rotating shaft 210 by the positioning structure, the user rotates the rotating sleeve 310. The two rotating sleeves 310 rotate synchronously through the transmission sprocket and transmission chain. Under the action of the thread, the rotating sleeve 310 moves downward along the lifting sleeve, causing the fixed base plate 300 to move downward. The fixed base plate 300 fits into the assembly base plate 100. Under the action of the suction cup 320, the fixed base plate 300 and the assembly base plate 100 are connected, which can support the positioning ring and the detection cylinder 400. After the fixed base plate 300 and the assembly base plate 100 are connected, the positioning structure is disengaged from the rotating shaft 210 to prevent it from affecting the rotation detection of the rotating shaft 210.

[0032] like Figures 3 to 5As shown, this embodiment provides a convenient multi-functional motor fault detection device. The inner ring of the positioning ring is provided with a positioning structure. The positioning structure includes an adjustment groove 530, which is opened inside the positioning seat 500. The inner wall of the adjustment groove 530 is provided with multiple through holes, and a positioning screw 520 passes through the through holes. One end of the positioning screw 520 extends to the inner ring of the positioning seat 500. Multiple positioning sleeves 521 are rotatably installed inside the adjustment groove 530. One end of the positioning screw 520 extends into the interior of the positioning sleeve 521. One end of the positioning sleeve 521 is movably inserted into the outer side of the positioning seat 500 and is equipped with a transmission gear 522. An adjustment ring 510 is rotatably installed on the outer side of the positioning seat 500. The inner ring of the adjustment ring 510 is provided with a transmission gear ring 511 that meshes with the transmission gear 522.

[0033] In this embodiment, when the positioning seat 500 and the detection cylinder are fitted onto the rotating shaft 210, the user rotates the adjusting ring 510. The adjusting ring 510 drives the positioning screw sleeves 521 to rotate via the transmission gear ring 511 and the transmission gear 522. As multiple positioning screw sleeves 521 rotate, the positioning screw 520 moves towards the inner ring of the positioning seat 500 under the action of the thread, causing the positioning screw 520 to engage with both sides of the rotating shaft 210. This positions the positioning seat 500 and the detection cylinder at a position concentric with the rotating shaft 210, facilitating the detection cylinder's inspection of the rotating shaft 210.

[0034] The positioning screw 520 has grooves 523 on both sides and sliders 524 on both sides of the inner wall of the through hole. The sliders 524 are slidably connected to the grooves 523. Under the action of the grooves 523 and the sliders 524, the positioning screw 520 cannot rotate, thus preventing the positioning screw 520 from rotating with the positioning sleeve 521 and affecting the movement of the positioning screw 520.
