[0022] In this embodiment, a rotating handle 12 is fixedly connected to the bottom of the support rod 10, and a screw rod 11 is fixedly connected to the bottom of the rotating handle 12. A lifting plate 13 is threadedly sleeved on the circumferential surface of the screw rod 11, and a threaded hole matching the screw rod 11 is opened in the middle of the lifting plate 13.

[0023] In this embodiment, the two sides of the lifting plate 13 are rotatably connected to the second connecting plates 15 , and the tops of the two second connecting plates 15 are rotatably connected to the bottoms of the adjacent extrusion plates 16 .

[0024] In this embodiment, rectangular holes 701 are formed at the bottom of the two side panels 7 , and the rectangular holes 701 are matched with the rotating handles 12 . The user rotates the rotating handles 12 through the rectangular holes 701 to achieve the lifting and lowering of the lifting plate 13 .

[0025] In this embodiment, two fixing rods 5 are fixedly connected to the middle position at the bottom of the base plate 1, and the bottoms of the two fixing rods 5 are fixedly connected to the same fixing plate 4. An electric push rod 6 is fixedly connected to the middle position at the top of the fixing plate 4. The top of the electric push rod 6 passes through the base plate 1 and is rotatably connected to the bottom of the screw rod 11. A circular hole matching the electric push rod 6 is opened in the middle position of the base plate 1. Through the setting of the electric push rod 6, the top plate 9 is lifted up to the transmission housing, and at the same time, the two extrusion plates 16 are driven away from each other.

[0026] In this embodiment, support plates 2 are fixedly connected to both sides of the bottom of the base plate 1, and two universal wheels 3 are fixedly connected to the bottom of the two support plates 2. The provision of the universal wheels 3 facilitates the movement of the device.

[0027] Working principle: A transmission housing inner cavity end face positioning device. When in use, the transmission housing is sleeved on the two side plates 7, and the transmission housing is supported by the top plate 9. The electric push rod 6 is started, so that the screw rod 11 rotates the handle 12 and the top plate 9 rises. When the screw rod 11 rises, the lifting plate 13 rises accordingly. When the lifting plate 13 rises, the first connecting plate 14 and the second connecting plate 15 approach each other, so that the extrusion plates 16 on both sides move away from each other until the arc-shaped rubber pad 17 contacts the inner cavity of the transmission housing. As the electric push rod 6 continues to extend, the transmission housing is fixedly positioned. The setting of the counterweight block 18 ensures that the two extrusion plates 16 are always in a vertical state. When different transmission housings are fixedly positioned, the rotating handle 12 is rotated to rotate the screw rod 11, so that the lifting plate 13 rises or falls along the screw rod 11, thereby achieving effective positioning of transmission housings of different sizes.
