[0002] During the motor testing process, the stable installation of the motor is a key factor to ensure the accuracy and reliability of the test. The motor needs to be firmly installed on the testing tooling so as to be effectively connected to the testing equipment and simulate the actual working conditions. At present, there are various motor testing and fixing toolings on the market, but each tooling has its specific applicable scenarios, advantages and disadvantages.

[0003] The prior art discloses a motor testing and fixing tooling with the publication number of CN220120851U, which includes a main body disc. A clamping groove is provided in the middle of the main body disc. The upper side of the clamping groove is two consecutive outer arcs, the side edges are both two consecutive inner arcs, and the bottom side is a sector. Mounting screw holes are provided on the top surfaces of the two inner arcs. The clamping groove is sleeved on the front end cover of the motor, and the bottom surface is fixedly connected with the bottom of the front end cover of the motor through bolts and the mounting screw holes. Fixing screw holes are provided on the top surface of the main body disc. Compared with the prior art, it can fix the motor on the test bench for detection, and multiple chamfers can facilitate the installation and disassembly. However, although this tooling meets the requirements of motor testing to a certain extent, there are still some deficiencies.

[0004] Firstly, although the design of the tooling takes into account the flange surface structure of the motor, for motors of different models, the sizes and shapes of their flange surfaces may be different, which may cause the tooling to not perfectly fit other models of motors.

[0005] Secondly, the tooling does not consider the requirements of picking and placing and weight reduction, but there may be problems of inconvenient operation during the actual use process. Content of the Utility Model

[0006] To solve the above-mentioned technical problems or one of the technical problems existing in the prior art, the utility model discloses a motor testing tooling, which includes a circular plate. A circular groove and a hollow groove are opened on one surface of the circular plate. The circular groove is arranged at the center of the circular plate. A groove is provided on the other surface of the circular plate. A central hole penetrating the groove and the circular groove is opened at the center of the circular groove. A U-shaped slot is provided on the hollow groove.

[0007] Furthermore, a plurality of mounting holes are circumferentially arranged in an array on the top surface of the circular groove.

[0008] Furthermore, countersunk screw holes are also opened on the circular plate.

[0009] Furthermore, the countersunk screw holes are arranged at the edge of the top surface of the circular plate.

[0010] Further, there are two hollow grooves, which are arc-shaped and arranged on the outer edge of the circular plate.

[0011] Further, the U-shaped slot is arranged at one end of one of the hollow grooves.

[0012] Further, the groove is annular and arranged at the center of the circular plate.

[0013] Compared with the prior art, the utility model is ingeniously designed, enabling accurate positioning during motor testing, facilitating the insertion of fingers, making it convenient to pick up and place the tooling, and having the effect of weight reduction. Description of the Drawings

[0014] Figure 1 It is a schematic structural diagram of one side of the utility model;

[0015] Figure 2 It is a schematic structural diagram of the other side of the utility model. Detailed Embodiment

[0016] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the utility model.

[0017] Please refer to Figure 1 、 2 The technical solution adopted by the utility model shown is: a motor testing tooling, including a circular plate 1. On one side of the circular plate 1, there are a circular groove 2 and a hollow groove 4. The circular groove 2 is arranged at the center of the circular plate 1. On the other side of the circular plate 1, there is a groove 6. A central hole 3 that penetrates the groove 6 and the circular groove 2 is opened at the center of the circular groove 2. A U-shaped slot 5 is arranged on the hollow groove 4.

[0018] Preferably, a plurality of mounting holes 11 are circumferentially arranged in an array on the top surface of the circular groove 2. The mounting holes 11 correspond to the hole positions of the motor flange to adapt to the flange surface of the motor, enhancing the connection strength between the motor and the tooling and improving the accuracy and reliability of the test.

[0019] Preferably, there are also countersunk screw holes 12 opened on the circular plate 1 for connecting the tooling to the test bench frame, making the connection more flat, avoiding the protrusion of the bolt head from affecting the stability and aesthetics of the tooling. At the same time, the countersunk screw holes can also better withstand the tensile force of the bolts and improve the stability of the connection.

[0020] Preferably, the countersunk screw hole 12 is provided at the edge of the top surface of the circular plate 1, so that the connection between the tooling and the test bench is more uniform, improving the stability of the overall structure of the tooling. At the same time, the edge position also facilitates the operator to tighten and disassemble the bolts.

[0021] Preferably, there are two arc-shaped hollow grooves 4 provided at the outer edge of the circular plate 1. This not only reduces the weight of the tooling, making handling and installation more convenient, but also provides an operating space, facilitating the operator's fingers or tools to reach in for installation and adjustment.

[0022] Preferably, the U-shaped slot 5 is provided at one end of one of the hollow grooves 4 for corresponding to the lifting ring of the motor and positioning the tooling, making the positioning more accurate.

[0023] Preferably, the groove 6 is annular and is provided at the center of the circular plate 1 to achieve precise positioning and fixing of the motor, avoiding the shaking and displacement of the motor during the test, and improving the accuracy and reliability of the test.

[0024] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
