[0003] For example, patent (CN210252777U) discloses an anti-rust treatment device for processing motor accessories, including a base. A paint box is arranged on the outer wall of one side of the base, and a painting mechanism is arranged at the top of the paint box; a rectangular chute is opened on the outer wall of one side of the base, and a lead screw is fixed to the inner wall of the rectangular chute through a bearing. A first motor is arranged on the inner wall of one side of the rectangular chute, and the output shaft of the first motor is in transmission cooperation with the lead screw through a coupling; several workpiece clamps are arranged at one end of the lead screw. The utility model can horizontally move the workpiece clamp through the transmission of the lead screw for assembly line processing, improve the efficiency of workpiece anti-rust treatment, reduce the manual labor intensity, can reasonably control the spraying amount through a solenoid valve, and control the spraying range according to the number of opened solenoid valves. By setting a push rod motor, the clamping of workpieces of different specifications can be satisfied. In addition, by installing a second motor, the workpiece can be automatically rotated, so that a comprehensive painting operation can be completed.

[0004] When using the above technology, it is found that the following technical problems exist in the prior art: When the prior art is used, the motor shell is often not fixed stably, and it is not convenient to fix the shell with different diameters, resulting in the inclination of the motor shell during rotation painting, resulting in uneven spraying surfaces, thereby affecting the work efficiency. Therefore, we design a surface treatment device for motor shells to provide another technical solution for the above technical problems. Summary of the Utility Model

[0025] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0026] Embodiment 1

[0027] Referring to Figures 1-4 , a surface treatment device for a motor housing, comprising a chassis 1. A support plate 2 is fixed to the bottom end inside the chassis 1. A servo motor 9 is fixed to the bottom end of the support plate 2. The output end of the servo motor 9 passes through the support plate 2 and is fixed with a lead screw 14. An outer clamping mechanism for fixing housings with different diameters is arranged on the outer side of the lead screw 14;

[0028] During use, by placing the housing inside the chassis 1, and then using the outer clamping mechanism to fix housings with different diameters, the stability of the housing fixation is effectively increased. Then, the servo motor 9 is started to drive the lead screw 14, the outer clamping mechanism and the housing to rotate synchronously, which is convenient for improving the uniformity of the spraying of the housing by the device, thereby promoting the work efficiency and quality;

[0029] The outer clamping mechanism includes a circular limit block 10, a linkage rod 11, a transmission rod 12, a circular slider 15 and a threaded drive block 13. A circular limit block 10 is fixed to the top end of the lead screw 14. A plurality of chutes are opened inside the circular limit block 10. The inner side of the chute is rotatably connected with a linkage rod 11. The bottom end of the linkage rod 11 is rotatably connected with a transmission rod 12. A circular slider 15 is slidably connected to the outer side of the lead screw 14. The outer side of the circular slider 15 is rotatably connected with the transmission rod 12. A threaded drive block 13 is threadedly connected to the outer side of the lead screw 14 and located below the circular slider 15;

[0030] Specifically, when the housing is processed and sprayed, the housing is sleeved on the outer side of the circular limit block 10 at this time. Then, the threaded drive block 13 is rotated upward. The threaded drive block 13 is rotatably connected with the circular slider 15, so that the circular slider 15 moves upward along the length of the lead screw 14. The circular slider 15 drives the transmission rod 12 to squeeze the linkage rod 11. Therefore, the connection part of the linkage rod 11 and the transmission rod 12 expands in a direction away from the lead screw 14, which is beneficial to externally clamp and fix housings with different diameters;

[0031] A spraying mechanism for spraying the housing is arranged at the top end of the chassis 1. The spraying mechanism includes a storage tank 3, a conduit 5, a water pump 6 and a nozzle 8. The storage tank 3 is fixed to the top end of the chassis 1. A feed port 4 is opened at the top end of the storage tank 3. The water pump 6 is fixed to the top end inside the chassis 1. The conduits 5 are fixed to both ends inside the chassis 1. Nozzles 8 are assembled at one ends of the two conduits 5 close to each other. The output end of the water pump 6 is respectively fixed to the conduit 5;

[0032] After the outer shell is fixed, the output end of the servo motor 9 drives the circular limit block 10, the linkage rod 11, the transmission rod 12, the threaded drive block 13, the lead screw 14, the circular slider 15 and the outer shell to rotate synchronously. Then, by pouring the protective pigment into the storage tank 3, the protective pigment inside the storage tank 3 is sprayed from the nozzle 8 along the conduit 5 through the output end of the water pump 6, thereby effectively spraying the rotating outer shell evenly, which is convenient for improving the uniformity of spraying of the outer shell;

[0033] A funnel 7 is fixed inside the chassis 1 and below the support plate 2. A number of flow holes are evenly arranged inside the funnel 7, and a water outlet is arranged at the bottom end inside the chassis 1, effectively flowing the sprayed protective pigment from the flow holes into the funnel 7 and discharging it orderly from the water outlet.

[0034] The use process of a surface treatment device for a motor outer shell provided by the present utility model is as follows:

[0035] Working principle: When in use, when the outer shell is processed and sprayed, the outer shell is placed outside the circular limit block 10 for sleeving. Then, by rotating the threaded drive block 13 upward, the threaded drive block 13 is rotatably connected to the circular slider 15, so that the circular slider 15 moves upward along the length of the lead screw 14. The circular slider 15 drives the transmission rod 12 to squeeze the linkage rod 11. Therefore, the connection between the linkage rod 11 and the transmission rod 12 expands away from the lead screw 14, which is beneficial to externally clamp and fix the outer shell with different diameters;

[0036] Finally, by pouring the protective pigment into the storage tank 3, the protective pigment inside the storage tank 3 is sprayed from the nozzle 8 along the conduit 5 through the output end of the water pump 6. Then, the output end of the servo motor 9 is started to drive the circular limit block 10, the linkage rod 11, the transmission rod 12, the threaded drive block 13, the lead screw 14, the circular slider 15 and the outer shell to rotate synchronously, thereby effectively spraying the rotating outer shell evenly, which is convenient for improving the uniformity of spraying of the outer shell.
