[0002] The motor includes a housing and an output shaft disposed on the housing. The output shaft can rotate relative to the motor housing after the motor is powered on.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, a motor detection device provided by an embodiment of the present application comprises a frame 1, a conveyor line 2 arranged along the X direction, a verticality detection mechanism 3, a coaxiality detection mechanism 4 and an axis runout detection mechanism 5 sequentially arranged on one side of the conveyor line 2, characterized in that: the coaxiality detection mechanism 4 is arranged on a No. 1 support 41 on the frame 1, a lifting frame 42 slidably arranged on the No. 1 support 41, a No. 1 driving component 43 fixedly arranged on the No. 1 support 41 for driving the lifting frame 42 to lift, a No. 1 displacement detection component 44 fixedly arranged on the frame 1, a No. 1 jacking component arranged below the No. 1 conveyor line 2, a rotation driving component 47 arranged on the lifting frame 42 and a No. 1 charging component 46,

[0023] It should be noted that the motor 100 to be tested is placed on a carrier, and the carrier is transported along the conveyor line 2 .

[0024] In actual use, the motor 100 to be tested is transported through the No. 1 conveyor line 2, and then the motor 100 to be tested passes through the verticality detection mechanism 3 for verticality detection, passes through the coaxiality detection mechanism 4 for coaxiality detection, and passes through the shaft runout mechanism for detection of the circumferential surface when the shaft rotates. In the coaxiality detection mechanism 4, the carrier plate and the motor 100 to be tested are lifted up by the No. 1 lifting component, and then the lifting frame 42 is driven downward by the No. 1 driving component 43, so that the rotating driving component 47 presses the motor housing from above the motor 100 to drive the motor housing to rotate synchronously, and the motor 100 to be tested is charged by the No. 1 charging component 46, and the No. 1 displacement detection component 44 detects whether the housing of the motor 100 to be tested and the output shaft of the motor 100 to be tested are concentric.

[0025] In the above design, the coaxiality detection mechanism 4 realizes the coaxiality detection of the motor 100 to be tested when the housing of the motor 100 to be tested is rotating but the output shaft of the motor 100 to be tested is fixed. It can detect whether the lower end surface of the housing of the motor 100 to be tested is horizontal, and more comprehensively test the concentricity of the output shaft and the housing.

[0026] Specifically: Figure 3 and Figure 4 As shown, the rotary drive assembly 47 includes a driving pulley arranged on the lifting frame 42, a driven pulley 472 arranged on the lifting frame 42, a synchronous belt wound around the driving pulley and the driven pulley 472, a No. 1 motor 473 arranged on the lifting frame 42 for driving the driving pulley, a rotating member 474 fixedly arranged at the lower end of the driven pulley 472, a servo electric cylinder 475 arranged on the lifting frame 42, and an upper clamping rod 476 arranged at the output end of the servo electric cylinder 475. The No. 1 charging assembly 46 includes a fixed A connecting member 461 fixedly arranged on the rotating member 474, a No. 1 screw rod 462 arranged on the connecting member 461 along the Z direction, a No. 1 plate 463 driven by the No. 1 screw rod 462, a No. 2 cylinder 464 arranged on the No. 1 plate 463 along the Y direction, a charging head fixedly arranged at the output end of the No. 2 cylinder 464, and a conductive slip ring 465 arranged on the lifting frame 42 and connected to the charging head, and the upper clamping rod 476 passes through the driven pulley 472 and the rotating member 474 to clamp the output shaft of the motor 100 to be tested.

[0027] In actual use, the lifting frame 42 is driven downward by the No. 1 driving component 43, so that the rotating part 474 presses the motor from the motor casing, and the motor 100 to be tested is lifted from the bottom of the motor output shaft by the No. 1 lifting component, and the upper clamping rod 476 is driven by the servo electric cylinder 475 to press from the upper end of the output shaft of the motor 100 to be tested. Then, the charging head is driven by the No. 2 cylinder 464 to charge the motor 100 to be tested, and then the No. 1 motor 473 drives the active pulley to rotate, and the transmission of the synchronous belt drives the driven pulley 472 to rotate, and drives the rotating part 474 to rotate synchronously, so that the No. 1 charging component 46 and the casing of the motor 100 to be tested rotate synchronously. During the rotation process, the lower end of the casing of the motor 100 to be tested is detected by the No. 1 displacement detection component 44. If the test result of the No. 1 displacement detection component 44 deviates from the preset value, it means that the coaxiality of the output end and the output shaft of the motor 100 to be tested is unqualified.

[0028] In the above design, the structural design of the transmission drive component and the No. 1 charging component 46 can facilitate the rotation of the housing of the motor 100 to be tested and ensure that the output shaft of the motor 100 to be tested is fixed, thereby making it easier to test the No. 1 displacement detection component 44.

[0029] Specifically: Figure 4 As shown, the No. 1 displacement detection component 44 includes a No. 1 seat 441 fixedly arranged on the frame 1, a No. 1 cylinder A442 arranged on the No. 1 seat 441 along the Y direction, a No. 1 connecting plate 443 arranged at the output end of the No. 1 cylinder A442, a No. 1 cylinder B444 arranged on the No. 1 connecting plate 443 along the X direction, a No. 1 cylinder C445 fixedly arranged at the output end of the No. 1 cylinder B444 along the Z direction, a connecting block arranged at the output end of the No. 1 cylinder C445, a No. 1 displacement sensor 446 fixedly arranged on the connecting block, and a No. 3 displacement sensor 447, the sensing end of the No. 1 displacement sensor 446 corresponds to the lower end of the outer side of the motor 100 to be tested, and the sensing end of the No. 3 displacement sensor 447 is tested with the circumference of the lower end of the motor 100 to be tested.

[0030] In actual use, the No. 1 connecting plate 443 is driven to move in the Y direction by the No. 1 cylinder A442, thereby driving the No. 1 cylinder B444 to move synchronously, and the No. 1 cylinder C445 is driven to move in the Z direction by the No. 1 cylinder B444, and the connecting block and the No. 1 displacement sensor 446 are driven to move synchronously by the No. 1 cylinder C445, so that the sensing end of the No. 1 displacement sensor 446 is abutted against the outer lower end of the motor 100 to detect whether the lower end surface of the outer casing of the motor 100 to be tested is flush, and the circumferential surface of the lower end of the outer casing of the motor 100 to be tested is tested by the No. 3 displacement sensor 447 to detect whether the trajectory of the outer periphery of the axial hole of the motor 100 to be tested for installing the output shaft is stable during rotation.

[0031] In the above design, the structural design of the No. 1 displacement detection component 44 can detect the flatness of the lower end surface of the housing of the motor 100 to be tested. Since the output shaft of the motor 100 to be tested is vertically fixed, it is possible to test whether there is a deviation in the concentricity between the housing of the motor 100 to be tested and the output shaft of the motor 100 to be tested.

[0032] Specifically: Figure 5 As shown, the shaft runout detection mechanism 5 includes a clamping and flipping assembly 51 arranged on the frame 1, an axle end detection assembly 52 arranged on the frame 1, and a No. 2 jacking assembly arranged below the conveyor line 2. The clamping and flipping assembly 51 includes a No. 3 seat 511 arranged on the frame 1, a No. 3 guide rail 512 vertically arranged on the No. 3 seat 511, a lifting plate 513 slidingly arranged on the No. 3 guide rail 512, and a No. 3 driving assembly 514 fixedly arranged on the No. 3 seat 511 for driving the lifting plate 513 to rise and fall. A rotating cylinder 515 with its output end facing the conveyor line 2 and a cylinder clamp 516 fixedly arranged on the output end of the rotating cylinder 515, the shaft end detection component 52 includes a No. 4 seat 521 arranged on the frame 1, a No. 2 charging component 522 arranged on the No. 4 seat 521, a No. 1 test piece 523 arranged on the No. 4 seat 521 for testing the circumferential surface of one end of the output shaft of the motor 100 to be tested, and a No. 2 test piece 524 for testing the circumferential surface of the other end of the output shaft of the motor 100 to be tested.

[0033] In actual use, when the motor 100 to be tested is transported to the corresponding position of the shaft runout detection mechanism 5, the carrier plate is driven to rise by the No. 2 lifting component, and then the motor 100 to be tested is clamped and flipped by the clamping and flipping component 51 so that the motor 100 to be tested is horizontal along the axial direction. The specific actions are: the lifting plate 513 is driven downward by the No. 3 driving component 514, so that the cylinder clamp 516 grabs the motor 100 to be tested, and then the No. 3 driving component 514 drives the lifting plate 513 to rise, and the rotating cylinder 515 drives the cylinder clamp 516 to flip 90°, and the No. 1 test piece 523 and the No. 2 test piece 524 are moved to the test position of the motor 100 to be tested in advance, and then the No. 2 charging component 522 is used to charge the motor 100 to be tested. During the rotation of the output shaft of the motor 100 to be tested, the No. 1 test piece 523 and the No. 2 test piece 524 realize the detection of the circumferential surface of the output shaft of the motor 100 to be tested.

[0034] In the above design, the structural design and specific implementation method of the shaft runout detection mechanism 5 can be used to test whether the circumferential surface of the output shaft of the motor 100 to be tested is stable during rotation.

[0035] Specifically: Figure 6As shown, a No. 4 guide rail is arranged on the No. 4 seat 521 along the X direction, and the No. 1 test piece 523 includes a No. 1 frame 231 slidably arranged on the No. 4 guide rail, a No. 4 screw rod 232 arranged on the No. 4 seat 521 along the X direction for driving the No. 4 frame to slide along the No. 4 guide rail, a No. 4 displacement sensor 233 arranged on the No. 1 frame 231, and a No. 1 contact head arranged at the sensing end of the No. 4 displacement sensor 233, the No. 1 contact head includes a fixed block 234 arranged at the sensing end of the No. 4 displacement sensor 233 and a roller 235 rollingly arranged on the fixed block 234, the axis of the roller 235 is parallel to the axis of the output shaft of the motor 100 to be tested, and the test path of the No. 4 displacement sensor 233 extends along the radial direction of the output shaft of the motor 100 to be tested.

[0036] In actual use, the No. 4 displacement sensor 233 is driven to move by the No. 4 screw rod 232, so that the roller 235 of the No. 1 contact head rolls in contact with the circumferential surface of the output shaft of the motor 100 to be tested. During the rotation of the motor 100 to be tested, if the shaft of the motor 100 to be tested swings, the value of the No. 4 displacement sensor 233 deviates from the error value.

[0037] In the above design, the structural design and specific implementation of the No. 1 test piece 523 can quickly test whether the output shaft end of the motor 100 to be tested is stable during the rotation process.

[0038] Specifically: Figure 6 As shown, the No. 2 test piece 524 includes a No. 2 frame 241 slidably set on the No. 4 guide rail, a No. 5 screw rod 242 set on the No. 4 seat 521 along the X direction for driving the No. 2 frame 241 to slide along the No. 4 guide rail, a No. 2 displacement sensor 243 set on the No. 2 frame 241 and a No. 2 contact head set at the sensing end of the No. 2 displacement sensor 243, the No. 2 contact head includes a No. 2 fixed block 234 set at the sensing end of the No. 2 displacement sensor 243 and an inclined rod 244 fixedly connected to the No. 2 fixed block 234, the end of the inclined rod 244 is against the circumferential surface of the output end of the motor 100 to be tested, and the test path of the No. 2 displacement sensor extends along the radial direction of the motor 100 to be tested.

[0039] In actual use, the No. 5 screw rod 242 is used to move the No. 2 frame 241, so that the No. 2 contact head contacts the other end of the output shaft of the motor 100 to be tested. Then, after the motor 100 to be tested rotates, the No. 2 displacement sensor 243 detects the displacement of the No. 2 contact head to monitor whether the other end of the output shaft of the motor 100 to be tested rotates stably.

[0040] In the above design, the structural design and specific implementation method of the second test piece 524 can effectively test whether the other end of the output shaft of the motor 100 to be tested is stable.

[0041] Specifically: Figure 1 As shown, the verticality detection mechanism 3 includes a vertical carrier 31 arranged at the side of the conveyor line 2, a No. 1 micrometer arranged on the vertical carrier 31, a transverse carrier 32 arranged at the side of the conveyor line 2, and a No. 2 micrometer arranged on the transverse carrier 32.

[0042] In actual use, the motor 100 to be tested is manually transferred from the conveyor line 2 to the vertical carrier 31 and kept in a vertical state, and then a No. 1 micrometer is used to test whether the motor 100 to be tested is clean. The motor 100 to be tested is manually transferred from the conveyor line 2 to the horizontal carrier 32 and kept in a horizontal state, and then a No. 2 micrometer is used to test whether the two ends of the output shaft of the motor 100 to be tested are flush.

[0043] In the above design, the verticality detection mechanism 3 can quickly detect whether the housing end and the output shaft end of the motor 100 to be tested are flush.

[0044] To further explain in detail, it should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
