[0030] like Figure 1 , 2 As shown, a motor casing fixture comprises a base 1 and a plurality of clamping assemblies 2, wherein the plurality of clamping assemblies 2 are distributed around a motor casing 3 to be processed, and are used to clamp and fix the motor casing 3 to be processed on the base 1, wherein the clamping assembly 2 comprises a rotating telescopic mechanism 21, a clamping arm 22, and a clamping hook 23, wherein the clamping hook 23 is arranged at the upper end of the clamping arm 22, and the lower end of the clamping arm 22 is arranged on the rotating telescopic mechanism 21, and the rotating telescopic mechanism 21 is arranged on the base 1; when clamping the motor casing 3 to be processed, the rotating telescopic mechanism 21 drives the clamping arm 22 to rotate and move, so as to drive the clamping hook 23 to rotate a predetermined angle and move downward to clamp and fix the motor casing 3 to be processed.

[0031] The clamping arm 22 is a rod-shaped structure, and a plug hole is provided at the lower end of the clamping arm 22 . The clamping arm is plugged into the upper end of the cylindrical cylinder body 212 through the plug hole.

[0032] The clamping arm 22 and the clamping hook 23 are integrally formed.

[0033] like Figure 3 , 4 As shown in Figures 5 and 6, the rotating and telescopic mechanism 21 uses high-pressure gas or high-pressure liquid as a power source. Specifically, the rotating and telescopic mechanism 21 includes a fixed sleeve 211, a cylindrical cylinder body 212, an exhaust pipe 213 and a piston (not shown in the figure). A slider 214 is provided on the side wall of the cylindrical cylinder body 212. An inclined long through hole 215 is provided on the sleeve wall of the fixed sleeve 211. The upper end of the cylindrical cylinder body 212 passes through the fixed sleeve 211 and is fixedly connected to the lower end of the clamping arm 22. The slider 214 is located in the inclined long through hole 215. The lower end of the exhaust pipe 213 is connected to the vacuum pipeline. The tube 213 is fixed on the base 1, and the upper end of the exhaust pipe 213 extends from the lower end of the cylindrical cylinder body 212 into the cylindrical cylinder body 212 and is fixedly connected to the piston. When clamping the motor housing 3 to be processed, the gas in the cylindrical cylinder body 212 is extracted through the exhaust pipe 213. Under the action of the air pressure difference, the cylindrical cylinder body 212 moves downward, and the slider 214 slides along the inclined elongated through hole 215. The slider 214 drives the cylindrical cylinder body 212 to rotate, and the cylindrical cylinder body 212 drives the clamping arm 22 to move and rotate.

[0034] The fixing sleeve 211 is provided with a fixing boss 216 . The fixing sleeve 211 extends into the mounting hole 11 on the base 1 . The fixing boss 216 is fixed to the base 1 by screws.

[0035] like Figure 1 , 7As shown, it also includes a limit seat 4, which is fixed on the base 1 by screws to position the motor housing to be processed. The limit seat 4 is provided with a limit groove 41, and the motor housing 3 to be processed is placed in the limit groove 41.

[0036] Working principle: first, place the motor casing 3 to be processed into the limiting groove 41 on the limiting seat 4. The inner diameter of the limiting groove 41 is adapted to the outer diameter of the motor casing 3 to be processed, so as to position the motor casing 3 to be processed; then, start the vacuum pump on the vacuum pipeline to form an air pressure difference between the inside and outside of the cylindrical cylinder body 212. The air extraction pipe 213 is fixed, and the cylindrical cylinder body 212 is movable. Under the action of external air pressure, the cylindrical cylinder body 212 moves downward. During the movement, the slider slides along the inclined elongated through hole 215 and is squeezed by the inclined elongated through hole 215, so that the slider drives the cylindrical cylinder body 212 to rotate, thereby driving the clamping hook 23 to move downward through the clamping arm 22. At the same time, the clamping hook 23 is rotated by a predetermined angle so that the clamping hook 23 is located directly above the motor casing 3 to be processed, thereby clamping and fixing the upper end of the motor casing 3 to be processed. When the processing is completed and the processed motor casing 3 needs to be removed, the vacuum pump is reversed to inflate the cylindrical cylinder body 212, so that under the action of air pressure, the cylindrical cylinder body 212 is pushed upward and rotated in the opposite direction. After the clamping hook 23 is reset, the clamping hook 23 is separated from the special-shaped motor casing 3 and rotated to one side of the special-shaped motor casing 3. At this time, the special-shaped motor casing 3 can be moved upward and taken out.

[0037] In addition, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples described in this specification without contradiction. Although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limiting the utility model. Those skilled in the art may change, modify, replace and modify the above embodiments within the scope of the utility model.
