DETAILED DESCRIPTION

[0025] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0027] A servo motor housing, such as Figure 1 As shown, the threaded hole 4 can fix the servo motor housing in a desired position by threaded connection, the activated carbon net 902 absorbs dust to prevent dust from entering the interior of the housing 1, and the shaft hole 14 allows the output rod of the motor to pass through and extend to the outside of the fixing plate 6.

[0028] like Figure 2 As shown, the fixed frame 5 is a square frame.

[0029] like Figure 3 As shown, the connecting groove 701 is close to the top of the fixed plate 6, the sliding rod 7012 prevents the connecting rod 7011 from falling off and limits the distance that the connecting rod 7011 moves left and right, the limit block 15 limits the moving distance of the limit ring 7015 to prevent the button 705 from detaching from the fixed frame 5, the button 705 passes through the opening 2 7016 and extends to the outside of the fixed frame 5, and the connecting rod 7011 passes through the opening 1 703 and extends to the outside of the fixed frame 5.

[0030] like Figure 4 As shown, through holes are provided on the left and right sides of the shell 1 for the heat sink 12 to pass through and extend to the outside of the shell 1. Condensate water can be injected into the cooling chamber 13 from the water inlet 10. The condensate water passes through the leakage hole 16 to increase the contact area between the heat sink 12 and the condensate water, and then is discharged from the drain port 11.

[0031] like Figure 5 As shown, the hot air in the housing 1 can be discharged from the vent hole 901 .

[0032] The front side of the fixing plate 6 in the present invention is fixedly connected with a handle, and the handle is convenient for pulling the fixing plate 6 out from the inside of the fixing frame 5 during disassembly.

[0033] When implementing, follow these steps:

[0034] 1) When installing the motor, first place the motor into the accommodating cavity 8 and press the two buttons 705 inward. The two buttons 705 drive the movable rods 708 to rotate respectively, and the two movable rods 708 drive the two connecting rods 7011 set on the top to move to the outside of the fixed frame 5 respectively;

[0035] 2) Then, the fixing plate 6 is placed in a close relationship inside the fixing frame 5. At this time, the two buttons 705 are released, and the two springs 704 rebound to drive the two buttons 705 to move to the outside of the fixing frame 5. The tops of the two movable rods 708 move closer to the fixing plate 6 so that the two connecting rods 7011 enter the insides of the two connecting grooves 701 respectively. The installation of the fixing frame 5 and the fixing plate 6 is completed.

[0036] 3) When disassembling, the two buttons 705 are pressed inwards to make the two movable rods 708 drive the two connecting rods 7011 to move away from the two connecting grooves 701 respectively, and the fixing plate 6 can be taken out;

[0037] 4) Finally, when the motor needs to be cooled, condensed water is injected from the water inlet 10 into the cooling chamber 13. The condensed water contacts the outside of the accommodating chamber 8 to reduce the temperature of the accommodating chamber 8. The hot air generated during the cooling is discharged from the vent 901.

[0038] To summarize, the servo motor casing, by setting up a loading and unloading structure 7, press the two buttons 705 inward to make the two connecting rods 7011 move to the outside of the fixed frame 5 respectively, and place the fixing plate 6 in the inside of the fixed frame 5, release the two buttons 705, and make the two connecting rods 7011 enter the inside of the two connecting grooves 701 respectively, so as to fix the fixing plate 6, and then press the two buttons 705 inward to make the two connecting rods 701 move away from the inside of the two connecting grooves 701 respectively, so as to remove the fixing plate 6, and by setting up a rear shell structure 9, the hot air inside the shell 1 can be discharged from the vent 901, and the activated carbon net 902 can absorb the dust entering the shell 1, thereby solving the problem of inconvenient disassembly of the motor casing for maintenance, wasting the time of maintenance workers, reducing the maintenance work efficiency and shortening the service life of the motor.
