Description

Technical Field

[0001] This application belongs to the field of motor manufacturing technology, and more specifically, relates to a stator testing device. Background Technology

[0002] During the manufacturing process of an electric motor, the stator needs to be wound and welded. After welding, the stator needs to undergo performance testing to improve the stator yield. Stator performance testing requires multiple tests, such as testing the stator's withstand voltage performance and thermistor performance. The commonly used testing method is as follows: the stator is supported by a support platform and moved to the withstand voltage test station by a traversing module, where it is tested. Subsequently, the traversing module continues to move the stator to the thermistor test station, where it is tested. In this way, by moving the stator to different test stations using the traversing module, the stator's performance can be tested one by one.

[0003] However, the stator needs to be tested one by one through a support platform and a transverse module, which results in low testing efficiency and cannot meet the needs of high-efficiency production operations. Utility Model Content

[0004] The purpose of this application is to provide a stator testing device to solve the problem in the related art that stator performance testing needs to be carried out at different testing stations, resulting in low stator testing efficiency.

[0005] To achieve the above objectives, the technical solution adopted in the embodiments of this application is as follows:

[0006] A stator testing apparatus is provided for testing the stator body, comprising:

[0007] Test socket;

[0008] A test conductive pin is mounted on the test socket and is used to make an electrical connection with the stator body;

[0009] Multiple test units are respectively installed on the test base, and each test unit is used to perform performance tests on the stator body.

[0010] A test transfer unit is connected to the test base and is used to drive the test base closer to or further away from the stator body.

[0011] In one embodiment, each of the test units includes two test conductive clamps for holding the stator body and a test drive for driving the two test conductive clamps to move closer or further apart from each other. The test drive is mounted on the test base, and the output end of the test drive is connected to the two test conductive clamps respectively.

[0012] In one embodiment, the test transfer unit includes a test transfer plate and a test transfer drive for driving the test transfer plate to reciprocate, the test seat is mounted on the test transfer plate, and the output end of the test transfer drive is connected to the test transfer plate.

[0013] In one embodiment, a first limiting stop is installed at one end of the test transfer drive, and a first limiting part is provided on the test transfer plate to cooperate with and block the first limiting stop; a second limiting part is provided at the other end of the test transfer drive, and a second limiting stop is installed on the test transfer plate to cooperate with and block the second limiting part.

[0014] In one embodiment, a slide rail is mounted on the test material transfer drive component, the slide rail being disposed between the first limiting stop and the second limiting stop, and the test material transfer plate is slidably mounted on the slide rail.

[0015] In one embodiment, the stator testing apparatus further includes a test frame, on which the test transfer unit is mounted.

[0016] In one embodiment, the test frame includes a test base, a test guide rod mounted on the test base, and a test support seat sleeved on the test guide rod, wherein the test transfer unit is mounted on the test support seat.

[0017] In one embodiment, a housing is fitted onto the stator body; the stator testing device further includes a thickness detection unit for detecting the thickness of the housing, the thickness detection unit being mounted on the test frame.

[0018] In one embodiment, the thickness detection unit includes a detection probe, a detection support for supporting the detection probe, and a detection drive for driving the detection probe closer to or further away from the housing; the detection drive is mounted on the test frame, and the output end of the detection drive is connected to the detection support.

[0019] In one embodiment, the thickness detection unit further includes an elastic element, one end of which abuts against the detection probe, and the other end of which abuts against the detection support.

[0020] The stator testing device provided in this application has at least the following beneficial effects: By installing test conductive pins and multiple test units on the test base, the test base can be driven closer to or further away from the stator body by a test transfer unit. When the test conductive pins are electrically connected to the stator body, the multiple test units can be electrically connected to the stator body respectively, thus allowing multiple properties of the stator body to be tested separately. In this way, by integrating multiple test units onto the test base, the travel distance of the stator body between multiple test stations is eliminated; multiple properties of the stator body can be tested simultaneously using multiple test units, which helps to improve the testing efficiency of the stator body.

[0042] Please see Figure 2 The stator testing apparatus provided in this application embodiment will now be described. This stator testing apparatus is used to perform performance testing on the stator body 10, and specifically includes a test base 1, test conductive pins 2, multiple test units 3, and a test transfer unit 4. The test conductive pins 2 and multiple test units 3 are respectively mounted on the test base 1. The test conductive pins 2 are electrically connected to the stator body 10, and each test unit 3 is used to perform performance testing on the stator body 10. The output end of the test transfer unit 4 is connected to the test base 1, and the test transfer unit 4 is used to drive the test base 1 closer to or away from the stator body 10. When the test conductive pins 2 are electrically connected to the stator body 10, the multiple test units 3 can be electrically connected to the stator body 10 respectively, thus enabling performance testing of the stator body 10. In this structure, by mounting the test conductive pins 2 and multiple test units 3 on the test base 1, the test transfer unit 4 can drive the test base 1 closer to or away from the stator body 10. When the test conductive pin 2 is electrically connected to the stator body 10, multiple test units 3 can be electrically connected to the stator body 10 respectively, thus allowing multiple performance characteristics of the stator body 10 to be tested separately. In this way, by integrating multiple test units 3 onto the test base 1, the travel distance of the stator body 10 between multiple test stations is eliminated; multiple performance characteristics of the stator body 10 can be tested simultaneously using multiple test units 3, which helps to improve the testing efficiency of the stator body 10.

[0043] In one embodiment, see Figure 1 and Figure 3As a specific embodiment of the stator testing device provided in this application, each testing unit 3 includes two test conductive clamps 31 and a test drive unit 32. The output end of the test drive unit 32 is connected to the two test conductive clamps 31 respectively. The test conductive clamps 31 are conductors; the test drive unit 32 can be a finger cylinder, and neither is specifically limited here. In this structure, the test drive unit 32 can drive the two test conductive clamps 31 to move closer or further apart. When the two test conductive clamps 31 move closer together, they clamp and fix the terminals 101 of the stator body 10, achieving electrical connection between the testing unit 3 and the stator body 10, thereby enabling performance testing of the stator body 10. When the two test conductive clamps 31 move further apart, they release the clamps from the terminals 101 of the stator body 10, at which point the test is complete.

[0044] The multiple test units 3 may include one or more of the following: a withstand voltage test unit for testing the withstand voltage performance of the stator body 10; a thermistor test unit for testing the thermistor performance of the stator body 10; and a basic test unit for testing the basic performance (such as current, voltage, resistance, etc.) of the stator body 10. These units can be adjusted and configured according to production needs. In this embodiment, the number of test units 3 may be three.

[0045] In one embodiment, see Figure 4 As a specific embodiment of the stator testing device provided in this application, the test transfer unit 4 includes a test transfer plate 41 and a test transfer drive 42. The test seat 1 is mounted on the test transfer plate 41, and the output end of the test transfer drive 42 is connected to the test transfer plate 41. The test transfer drive 42 can be a cylinder, electric cylinder, etc., and is not limited to any particular type. This structure allows the test seat 1 to be supported by the test transfer plate 41, facilitating its assembly and disassembly. The test transfer drive 42 drives the test transfer plate 41 and the test seat 1 to reciprocate, thereby moving the test conductive needle 2 and multiple test units 3 closer to or further away from the stator body 10. The reciprocating direction of the test transfer plate 41 is vertical. The stator body 10 can be supported by a support platform, which can be moved horizontally by a support transfer module. The support transfer module can be a cylinder / electric cylinder transmission mechanism, a lead screw transmission mechanism, a linear motor, etc., and is not limited to any particular type.

[0046] In one embodiment, see Figure 4 and Figure 5As a specific embodiment of the stator testing device provided in this application, a first limiting rod 421 is installed at one end of the test transfer drive member 42, and a first limiting part 411 is provided on the test transfer plate 41; a second limiting part 422 is provided at the other end of the test transfer drive member 42, and a second limiting rod 412 is installed on the test transfer plate 41. Both the first limiting part 411 and the second limiting part 422 can be stepped portions; the first limiting rod 421 and the second limiting rod 412 are elastic telescopic rods, thus achieving elastic buffer protection. The first limiting rod 421 is located above the second limiting part 422. This structure, through the cooperation of the first limiting stop 421 and the first limiting part 411, can limit the upward movement of the test transfer plate 41; through the cooperation of the second limiting stop 412 and the second limiting part 422, it can limit the downward movement of the test transfer plate 41. This can prevent the test seat 1 from being damaged by excessive stroke, such as the test conductive needle 2, multiple test units 3 and stator body 10.

[0047] In one embodiment, see Figure 4 As a specific embodiment of the stator testing device provided in this application, a slide rail 423 is mounted on the test transfer drive component 42. The slide rail 423 is located between the first limiting stop 421 and the second limiting stop 412, and the test transfer plate 41 is slidably mounted on the slide rail 423. The slide rail 423 extends along the sliding direction of the test transfer plate 41, specifically in a vertical direction. This structure, by connecting the test transfer plate 41 and the test transfer drive component 42 through the slide rail 423, improves the reliability and stability of the reciprocating movement of the test transfer plate 41 on the test transfer drive component 42.

[0048] In one embodiment, see Figure 2 As a specific embodiment of the stator testing device provided in this application, the stator testing device further includes a test frame 5, on which a test transfer unit 4 is mounted. Specifically, a test transfer drive 42 is mounted on the test frame 5. This structure allows the test frame 5 to support the test transfer unit 4, thus positioning the test transfer unit 4 above the stator body 10 for convenient performance testing of the stator body 10.

[0049] In one embodiment, see Figure 6As a specific embodiment of the stator testing device provided in this application, the test frame 5 includes a test base 51, a test guide rod 52 mounted on the test base 51, and a test support 53 sleeved on the test guide rod 52. The test transfer unit 4 is mounted on the test support 53. Specifically, the test support 53 has a through hole for the test guide rod 52 to pass through, and screws, bolts, and other fasteners are installed on the test support 53. The fasteners can lock the test support 53 to different positions on the test guide rod 52, thereby adjusting the height of the test transfer unit 4. The test transfer drive 42 is mounted on the test support 53. In this structure, by mounting the test transfer unit 4 on the test support 53 and adjusting the mounting position of the test support 53 on the test guide rod 52, the position of the test transfer unit 4 can be adjusted.

[0050] In one embodiment, see Figure 1 and Figure 2 As a specific embodiment of the stator testing device provided in this application, a housing 20 is fitted onto the stator body 10; the stator testing device also includes a thickness detection unit 6 mounted on the test frame 5. With this structure, the thickness of the housing 20 can be detected by the thickness detection unit 6.

[0051] In one embodiment, see Figure 7 As a specific embodiment of the stator testing device provided in this application, the thickness detection unit 6 includes a detection probe 61, a detection support base 62 supporting the detection probe 61, and a detection drive unit 63 mounted on the test frame 5. The output end of the detection drive unit 63 is connected to the detection support base 62. The detection drive unit 63 can be a cylinder, an electric cylinder, etc., and is not limited to any particular type. In this structure, the detection drive unit 63 can drive the detection support base 62 and the detection probe 61 closer to or further away from the housing 20. When the detection probe 61 contacts the housing 20, it can calculate the thickness of the housing 20 based on the detected resistance.

[0052] Optionally, the test fixture 5 also includes a thickness support 54 sleeved on the test guide rod 52. The thickness support 54 is installed and fixed by fasteners such as screws and bolts; the detection drive component 63 is installed on the thickness support 54. This structure allows the position of the thickness detection unit 6 to be adjusted by installing the thickness support 54 at different positions on the test guide rod 52, thus adapting to different housings 20 and stator bodies 10.

[0053] In one embodiment, see Figure 7As a specific embodiment of the stator testing device provided in this application, the thickness detection unit 6 further includes an elastic element 64. One end of the elastic element 64 abuts against the detection probe 61, and the other end of the elastic element 64 abuts against the detection support 62. The elastic element 64 can be a spring, which is sleeved on the detection probe 61. This structure, through the elastic element 64, can achieve elastic buffering of the detection probe 61, avoiding damage caused by hard contact between the detection probe 61 and the housing 20.

[0054] The above description is merely an optional embodiment of this application and is not intended to limit this application.
