Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically to a motor housing testing device used in motor manufacturing. Background Technology

[0002] Motor housing inspection mainly focuses on two core dimensions: First, appearance integrity inspection. Staff members meticulously inspect the surface of the housing for cracks, dents, scratches, deformation, and other damage through visual observation or with the aid of optical inspection equipment. They also check whether the coating is uniform, whether there is any peeling or color difference, to ensure that the housing can effectively isolate external dust and moisture and prevent internal components from being corroded. Second, precision inspection of key parts. The focus is on measuring the roundness of the housing's circular opening structure. Professional measuring tools such as roundness testers and micrometers are used to accurately control the shape error of the circular opening to ensure that it fits tightly with the matching components. This prevents excessive installation gaps, vibration and noise during operation, and even affects the stability of motor transmission due to substandard roundness.

[0003] In the mass production of electric motors, the accuracy and efficiency of traditional inspection methods can no longer meet the demands. Visual inspection relies on manual inspection, which is susceptible to lighting and fatigue, and is inadequate in identifying minute scratches and hidden cracks, resulting in a high rate of missed and false detections. Roundness measurement requires manual operation of micrometers and roundness testers for each piece, which is not only slow but also prone to data deviations due to differences in operating techniques, making it difficult to guarantee consistency. This model is time-consuming per unit, unable to match the high-speed operation of the production line, thus restricting overall production efficiency and making it difficult to mitigate quality risks through efficient re-inspection. It completely fails to meet the core requirements of the current electric motor industry for rapid inspection and efficient quality control. Summary of the Invention

[0004] To solve the above-mentioned problems, this utility model proposes a motor housing inspection device for motor production that can quickly perform accurate inspection and avoid visual inspection errors.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a motor housing inspection device for motor production, comprising: The testing frame includes a frame plate and support legs, wherein the support legs are fixedly disposed on the bottom surface of the frame plate and are provided in several manner; The detection seat is rotatably connected to the frame plate and is driven to rotate by a first geared motor fixed on the frame plate. A second geared motor is fixed on the seat, and a magnetic block is embedded in the output end of the second geared motor. High-definition industrial cameras are symmetrically fixed on both sides of the detection base on the frame plate; The ranging sensor is located above the frame plate, directly opposite the second output end of the geared motor. It is driven by a lead screw driver fixed on the frame plate to move radially along the second output end of the geared motor. The frame plate is provided with a heightening seat to support the lead screw driver. The positioning component includes a locator one and a locator two, which are respectively fixed on the detection seat and the elevation seat, and are arranged relative to each other and matched.

[0006] Furthermore, an arc-shaped support plate is fixedly provided on the bottom edge of the detection seat, and an annular guide groove matching the arc-shaped support plate is provided on the frame plate.

[0007] Furthermore, a support block is fixedly provided on the detection seat near the output end of the second geared motor and on the central axis of the second geared motor, and a ball bearing is embedded above the support block.

[0008] Furthermore, a bracket for fixing a high-definition industrial camera is fixed on the frame plate, and the high-definition industrial camera is tilted toward the output end of the geared motor.

[0009] Furthermore, the first locator is fixedly mounted on the detection seat near the output end of the second geared motor and located on the central axis of the output end of the second geared motor. The second locator is fixedly mounted on the side of the heightening seat near the detection seat and is at the same height as the first locator.

[0010] Compared with existing technologies, the advantages of this invention are as follows: the detection seat can be driven to rotate by a geared motor, and with the magnetic fixation of the motor housing and the auxiliary support of the ball bearings, the housing can rotate smoothly and stably. The high-definition industrial cameras on both sides are tilted to align with the detection area, eliminating blind spots and simultaneously capturing defects on the surface of the housing, replacing manual visual inspection and completely avoiding subjective errors. The positioning component can quickly calibrate the relative position of the housing and the ranging sensor. The lead screw driver drives the ranging sensor to move radially along the housing, accurately measuring the flatness of the end face without the need for repeated manual adjustments, greatly improving detection efficiency. The arc-shaped support plate and the annular guide groove enhance stability, ensuring that the equipment and housing do not shake during the detection process, guaranteeing the accuracy of camera shooting and sensor ranging, and achieving fast and accurate detection.

[0015] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 4 The detection seat 3 is rotatably connected to the frame plate 1 and is driven to rotate by a reduction motor 4 fixed on the frame plate 1. An arc-shaped support plate 12 is fixedly provided on the bottom edge of the detection seat 3. The frame plate 1 is provided with an annular guide groove that matches the arc-shaped support plate 12. This can provide auxiliary support and guidance for the rotating detection seat 3, prevent the detection seat 3 from shaking due to uneven force, and improve the stability of the detection process.

[0016] Combined with appendix Figure 1 Appendix Figure 2 A second geared motor 5 is fixedly mounted on the detection base 3. A magnetic block is embedded in the output end of the second geared motor 5. A support block 13 is fixedly mounted on the detection base 3 near the output end of the second geared motor 5 and on the central axis of the second geared motor 5. A ball bearing 14 is embedded above the support block 13, which can form auxiliary support for the bottom of the motor housing. At the same time, the ball bearing 14 can reduce the frictional resistance when the motor housing rotates, thus protecting the housing and ensuring its smooth rotation, and ensuring the continuity of detection.

[0017] Combined with appendix Figure 1 Appendix Figure 4 A high-definition industrial camera 6 is symmetrically fixed on both sides of the detection seat 3 on the frame plate 1. The frame plate 1 is fixed with a bracket 15 for fixing the high-definition industrial camera 6. The high-definition industrial camera 6 is tilted towards the output end of the geared motor 5, which allows the camera to be more accurately aimed at the area to be inspected on the motor housing, reducing blind spots and improving the accuracy of capturing defects on the housing surface.

[0018] Combined with appendix Figure 2 Appendix Figure 3 The ranging sensor 7 is located above the frame plate 1, directly opposite the output end of the second geared motor 5. It is driven by the lead screw driver 8 fixed on the frame plate 1 to move radially along the output end of the second geared motor 5. The frame plate 1 is provided with a heightening seat 9 to support the lead screw driver 8.

[0019] Combined with appendix Figure 2 Appendix Figure 3The positioning component includes a first locator 10 and a second locator 11, which are respectively fixed on the detection base 3 and the elevation base 9, and are arranged opposite to each other and matched. The first locator 10 is fixed on the detection base 3 near the output end of the second gear motor 5 and located on the central axis of the output end of the second gear motor 5. The second locator 11 is fixed on the side of the elevation base 9 near the detection base 3 and is at the same height as the first locator 10. This allows for quick calibration of the relative position between the motor housing and the ranging sensor 7, avoiding inaccurate ranging data due to positioning deviation and improving detection accuracy.

[0020] The specific implementation of this utility model is as follows: In use, the motor housing to be tested is first placed on the testing base 3, with the bottom of the housing adhering to the ball bearings 14 of the support block 13. The magnetic block at the output end of the second geared motor 5 attracts and fixes the center of the other end of the housing. The first geared motor 4 is started to drive the testing base 3 to rotate, and the arc-shaped support plate 12 slides along the annular guide groove of the frame plate 1 to assist in stabilization; simultaneously, the second geared motor 5 drives the housing to rotate, and the high-definition industrial camera 6 fixed on the two side brackets 15 synchronously captures images of the housing surface for testing. When testing the end face of the motor housing, the positioning assembly is activated. Precise calibration is achieved through the locator 10 on the testing base 3 and the locator 11 on the riser 9, ensuring accurate alignment between the housing and the distance sensor 7. At this time, only the second geared motor 5 is controlled to drive the motor housing to rotate. The lead screw driver 8 is activated to drive the distance sensor 7 to move radially along the housing, accurately measuring the flatness of the end face.
