[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] according to Figure 1-4 As shown: The utility model provides a reducer housing casting grinding device: it includes a support leg 1, which is fixedly connected to a support plate 2 and a bracket 3 in sequence upward; a cylindrical shell 5 is placed on the support plate 2, and an external grinding device 4 is arranged in the bracket 3; a connecting block 17 is fixedly connected to the bottom of the shell 5, and a mounting hole 18 is provided on the connecting block 17; a mounting box 6 is fixedly connected to the bottom of the support plate 2, and a connecting hole 11 connected to the mounting box 6 is provided on the support plate 2; the shell 5 is opened and removed, and the shell 5 covers the connecting hole 11; an internal grinding device 12 with the same structure as the external grinding device 4 is arranged in the mounting box 6, and the internal grinding device 12 extends into the shell 5 through the connecting hole 11; two fixed cylinders 15 are fixedly provided on the support plate 2, and a plug-in structure for inserting into the mounting hole 18 is provided in the fixed cylinder 15 for sliding up and down; a first vacuum cleaner 7 connected to the mounting box 6 is provided below the support plate 2.

[0021] By providing the internal grinding device 12 within the mounting box 6, after the housing 5 is fixed, the internal and external grinding devices 4 can be used to grind the housing 5 simultaneously, thereby improving the grinding efficiency. Furthermore, the mounting box 6 and the first vacuum cleaner 7 can collect debris and dust generated during the grinding process inside the housing 5, thereby preventing the grinding effect from being affected.

[0022] like Figure 2 、 3 As shown, an annular connecting groove 13 is provided in the support plate 2, and a connecting hole 14 connected to the connecting groove 13 is provided on the upper surface of the support plate 2, which can facilitate some debris on the support plate 2 to fall into the connecting groove 13; a second vacuum cleaner 10 connected to the connecting groove 13 is provided under the support plate 2, which can suck away the dust on the support plate 2 through the connecting hole 14 and the connecting groove 13.

[0023] like Figure 4As shown, the plug-in structure includes a lifting plate 20, a lifting rod 22, and an insertion rod 23. The lifting plate 20 is slidably mounted within the fixed cylinder 15, and a guide slot 21 is defined on one side of the fixed cylinder 15. The lifting rod 22 is positioned within the guide slot 21 and is fixedly connected to the lifting plate 20. The insertion rod 23 is inserted into the mounting hole 18 and is fixedly connected to the lifting rod 22. A screw 19 is rotatably mounted within the fixed cylinder 15, and the lifting plate 20 is threadedly connected to the screw 19. The arrangement of the lifting rod 22 and the guide slot 21 restricts the rotation of the lifting plate 20, thereby converting the rotation of the screw 19 into movement of the lifting plate 20, which in turn drives the insertion rod 23 to move via the lifting rod 22.

[0024] The installation box 6 is provided with a first opening 8 for conveniently opening the installation box 6 to remove the debris; the support plate 2 is provided with a second opening 9 for conveniently opening the connection groove 13 to remove the debris in the connection groove 13.

[0025] A positioning ring 16 is fixedly provided in the communicating hole 11 , and the positioning ring 16 is inserted into the housing 5 , so as to facilitate the positioning of the cylindrical housing 5 .

[0026] Principle of the utility model

[0027] like Figure 3 As shown, when placing the housing 5, place the housing 5 on the support plate 2 and position the positioning ring 16 inside the housing 5, thereby performing a preliminary positioning of the cylindrical housing 5; align the mounting hole 18 on the connecting block 17 with the insertion rod 23, as shown in FIG. Figure 4 As shown, by turning the screw 19, the lifting plate 20 drives the insertion rod 23 downward until the insertion rod 23 is inserted into the mounting hole 18, thereby completing the fixing of the shell 5. After the shell 5 is installed, the internal grinding device 12 can also be extended into the shell 5; the external grinding device 4 and the internal grinding device 12 are started at the same time to grind the inside and outside of the shell 5 simultaneously; the first vacuum cleaner 7 and the second vacuum cleaner 10 are started at the same time, and the debris and dust generated by grinding the outside of the shell 5 can fall into the connecting groove 13 through the connecting hole 14. Due to the action of the second vacuum cleaner 10, the diffusion of dust on the support plate 2 can be reduced. Since the shell 5 is open downward, the debris generated by grinding the inside of the shell 5 can fall directly into the installation box 6 through the connecting hole 11 under the action of gravity, preventing the debris from remaining inside the shell 5 and affecting the grinding effect. At the same time, the dust can be sucked away by the first vacuum cleaner 7.

[0028] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
