[0016] like Figure 1-2 As shown, the motor housing clamping and positioning device includes a test bench 1, on which two oppositely arranged clamping plates 17 are installed. The clamping plates 17 are located on either side of the test bench 1 and are driven and moved by a cylinder 18. The inner side of the clamping plates 17 is arc-shaped, and an elastic buffer layer is fixed to the inner side of the clamping plates 17. The test bench 1 is provided with an elastic support portion 30 for placing the motor housing 24. The rear portion of the test bench 1 is fixedly connected to a column 3, on which a vertical slide 19 is provided. The vertical slide 19 is mounted on a vertical slider 20, and the vertical slider 20 is connected to a horizontal calibration plate 21. The elastic support portion 30 protects the bottom of the motor housing 24 and also provides a certain degree of freedom for the motor housing 24 after clamping. The elastic buffer layer can be a sponge, rubber pad, etc., which can protect the surface of the motor housing 24 and prevent scratches and crushing of the motor housing 24. At the same time, it provides a certain degree of freedom for the motor housing 24 located between the clamping plates 17, and the angle of the motor housing 24 can be adjusted within a certain angle range. The motor housing 24 is placed on the test bench 1. The cylinder 18 drives the clamping plate 17 to move, and the clamping plate 17 is used to clamp the motor housing 24, thereby fixing and positioning the motor housing 24. This facilitates subsequent measurement using measuring tools or installation of wiring harness connectors on the motor housing 24.

[0017] Furthermore, a magnet is fixedly connected to the upper end of the vertical slide rail 19, and a magnetic attraction portion 22 for the magnet to attract is provided on the horizontal calibration plate 21. After the horizontal calibration plate 21 is lifted, the magnetic attraction portion 22 is attracted by the magnet, thereby fixing the horizontal calibration plate 21.

[0018] Furthermore, the horizontal calibration plate 21 includes a main plate 31 and a plurality of support plates 32 fixedly connected to the main plate 31. The main plate 31 is detachably connected to the vertical slider 20. The shape of the horizontal calibration plate 21 can be customized according to the shape specifications of the motor housing 24.

[0019] Furthermore, a circular groove 33 is provided in the middle of the test bench 1, and a lifting platform 34 is provided in the circular groove 33. The elastic support portion 30 is located on the lifting platform 34, and the lifting platform 34 is driven up and down by a lifting drive mechanism. The lifting platform 34 drives the motor housing 24 up and down to adjust the height.

[0020] Furthermore, arc-shaped slide rails 35 are provided on both sides of the test bench 1, and rotating sliders 36 are provided on the arc-shaped slide rails 35. The cylinders 18 are fixedly mounted on the rotating sliders 36, and the rotating sliders 36 are driven by the rotating drive mechanism to move on the arc-shaped slide rails 35. When it is necessary to rotate the motor housing 24 and adjust the angle of the motor housing 24, while the clamping plate 17 clamps the motor housing 24, the rotating sliders 36 synchronously move a certain distance on the arc-shaped slide rails 35 to drive the motor housing 24 to rotate. Before the motor housing 24 rotates, the lifting platform 34 descends a certain height so that the motor housing 24 is separated from the lifting platform 34. After the rotation is completed, the lifting platform 34 rises to support the motor housing 24, the clamping plate 17 releases the motor housing 24, the rotating slider 36 is reset, and the clamping plate 17 clamps the motor housing 24 again.

[0021] Furthermore, a large gear 37 is provided under the test bench 1, and the large gear 37 is rotatably connected to the test bench 1. The rotating slider 36 is fixedly connected to the large gear 37 through a number of connecting rods 38. The test bench 1 is provided with an arc-shaped through hole 39 for the connecting rod 38 to move through. The rotation drive mechanism includes a motor 40, and the motor 40 drives the large gear 37 to rotate through the small gear 41.

[0022] Furthermore, the lifting drive mechanism includes a lifting cylinder 42 .
