[0002] The motor end cover, as the name implies, is the housing located at both ends of the motor, protecting the core components inside the motor. It is usually made of materials such as cast iron and aluminum alloy, and has good strength and sealing performance. The main functions of the motor end cover are: protecting the internal components of the motor from external influences, such as the entry of dust and objects, providing good sealing performance, avoiding the exchange of liquids or gases between the inside and outside of the motor, preventing the inside of the motor from being corroded, providing a heat dissipation function for the motor, and keeping the internal temperature of the motor within a safe range.

[0003] In the patent with the patent number CN219015215U, a concentricity detection tool for motor end covers is disclosed, including an end cover mounting member (1). Mounting holes (2) for connecting the motor end cover are provided around the end cover mounting member (1). A test hole (3) is provided in the middle of the end cover mounting member (1). A rotating shaft (4) is rotatably connected to the inner side of the test hole (3). A positioning member (5) for cooperating with the motor end cover is provided at the end of the rotating shaft (4). The utility model can detect the relative positions of the bearing mounting groove and the end cover hole of the motor end cover.

[0004] The above device has certain deficiencies when in use: when installing and detecting the motor end cover, the motor end cover is fixed on the end cover mounting member through the cooperation bolts of the end cover hole and the mounting hole. Since different motor specifications vary greatly, the assembled motor end covers will also have large differences. The positions of the mounting holes in the above device are fixed, and can perform positioning detection on motor end covers of a single specification. When facing motor end covers of other specifications, there may be inapplicable situations.

[0005] Therefore, the utility model provides a positioning tooling for motor end cover detection to solve the above problems. Content of the Utility Model

[0035] In the embodiment of the present utility model, the purpose of such a setting is that the positioning and fixing component 6 can clamp and fix motor covers 5 of different specifications, prevent the situation of position deviation during the test, and the test component 7 can detect the concentricity of the bearing installation groove and the end cover hole in the motor cover 5, preventing the situation of misalignment and inability to fix during the later installation.

[0036] Embodiment Two:

[0037] Please refer to Figures 1-4 , this embodiment provides a technical solution on the basis of Embodiment One: Limit rods 63 are fixedly installed on the sides of the two moving seats 64 away from each other. The ends of the limit rods 63 away from each other slidably penetrate through the corresponding L-shaped frames 62 and extend to the outside. The two clamping seats 65 are both arc-shaped. Anti-slip pads 66 are installed on the adjacent sides of the two clamping seats 65. The large gear 77 is meshed with the small gear 76, and the transmission ratio of the large gear 77 to the small gear 76 is 1:5. The bottom wall of the fixed seat 73 is in contact with the top wall of the square screw cylinder 710. A contact bolt 711 is screwed and installed on the front wall of the square screw cylinder 710. The contact bolt 711 is screwed through the square screw cylinder 710 and abuts and fixes with the screw column 712. The outer wall of the connecting bearing 72 is in contact with the inner wall of the bearing installation groove of the motor cover 5. The positioning column 71 is located in the end cover hole of the motor cover 5. Support legs 2 are fixedly installed at the four corners of the bottom wall of the workbench 1. A box door 3 is hingedly installed on the front wall of the workbench 1. A handle 4 is installed on the front wall of the box door 3;

[0038] In the embodiment of the present utility model, the purpose of such a setting is that the setting of the contact bolt 711 can abut and fix the screw column 712 installed in the square screw cylinder 710, prevent the situation that the screw column 712 rotates on the inner wall of the square screw cylinder 710 during the test. After the positioning column 71 enters the end cover hole of the motor cover 5, it can rotate smoothly without friction, and the end cover hole of the motor cover 5 meets the installation requirements.

[0039] At the same time, the content not described in detail in this specification belongs to the well-known prior art of those skilled in the art.

[0040] During operation, first connect the electric push rod 61 and the reduction motor 75 through an external power supply and a controller. Before testing the motor cover 5, place the motor cover 5 at the top of the workbench 1. Insert it into the bearing installation groove at the bottom of the motor cover 5 through the connecting bearing 72, and the positioning post 71 enters the end cover hole of the motor cover 5. Then, connect the electric push rod 61 through an external controller to push the moving seat 64 and the limit rod 63 to move. The limit rod 63 can prevent the moving seat 64 from shifting in position during movement. When the moving seat 64 drives the clamping seat 65 and the anti-slip pad 66 to move and approach the outer wall of the motor cover 5 until they are in contact and clamped, the anti-slip pad 66 can increase the friction with the outer wall of the motor cover 5 and improve the stability of clamping and fixing. After the motor cover 5 is fixed, start the positioning test on the motor cover 5. Control the reduction motor 75 through an external controller to drive the pinion 76 to rotate five circles and then stop. When the pinion 76 rotates and drives the large gear 77 to rotate, it immediately drives the connecting shaft 79 and the square screw barrel 710 to rotate. When the square screw barrel 710 rotates, it drives the fixed seat 73 and the positioning post 71 to rotate within the end cover opening of the motor cover 5. When the positioning post 71 rotates smoothly for one week within the end cover opening of the motor cover 5, it indicates that the concentricity of the bearing installation groove and the end cover hole meets the requirements, effectively preventing misalignment and jamming problems of the motor end cover during subsequent installation, preventing mismatching during the later installation process, and avoiding affecting the working efficiency of motor assembly. When testing motor covers 5 of other specifications, there will be differences in the specifications of the end cover holes faced. Therefore, the abutting bolt 711 can be removed, and then rotate the fixed seat 73 to drive the stud 712 to disengage from the screwed state with the inner wall of the square screw barrel 710, and then replace the matching positioning post 71 and connecting bearing 72.
