DETAILED DESCRIPTION

[0023] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0026] Reference Figures 1-6 The schematic structural diagram of the novel closed curved track grinding machine provided in the present application includes a workbench 1, a motor 2, a column 3, a movable bracket 4, a grinding wheel shaft 5, a grinding wheel 6, and a sleeve 7. The column 3 is vertically arranged on the workbench 1, the movable bracket 4 is slidably arranged on the column 3, the grinding wheel shaft 5 is vertically passed through the workbench 1, and the grinding wheel 6 is fixedly sleeved on the grinding wheel shaft 5. The motor 2 is arranged below the workbench 1 and is connected to drive the grinding wheel shaft 5 to rotate. The sleeve 7 is fixedly connected to the movable bracket 4 through a bearing 8. Moving the movable bracket 4 downward allows the sleeve 7 to slide onto the top of the grinding wheel shaft 5. Since supports are provided at both ends of the grinding wheel shaft 5, the rigidity and vertical accuracy of the grinding wheel 6 are improved. When in use, the movable bracket 4 can be separated from the grinding wheel shaft 5 by moving the movable bracket 4 upward, and the workpiece 16 surrounding the outside of the grinding wheel 6 can be removed.

[0027] like Figure 5As shown, a positioning sleeve 9 is also provided on the column 3. The positioning sleeve 9 is fastened to the column 3 by a fastening screw 10. The movable bracket 4 is pressed downwardly onto the positioning sleeve 9. The positioning sleeve 9 is used as a limit mechanism to limit the height of the movable bracket 4, making it suitable for use in occasions of different heights. Moreover, the column 3 is a cylindrical structure, so that the movable bracket 4 and the column 3 can also rotate, expanding the working space when taking and placing the workpiece 16 and avoiding bumps. The movable bracket 4 is provided with a gap 401 extending inwardly to the column 3, and the two sides of the gap 401 are connected by clamping screws 11. The opening and closing of the gap 401 is controlled by turning the clamping screws 11, thereby achieving the clamping and loosening of the movable bracket 4.

[0028] A frame 12 is located below the workbench 1. A horizontal adjustment mechanism is connected between the frame 12 and the workbench 1. A motor 2 is mounted on the frame 12. The horizontal adjustment mechanism comprises a horizontal adjustment screw 13. By controlling the height of the horizontal adjustment screw 13, the tilt of the upper workbench 1 can be adjusted. This allows for grinding specific locations on a workpiece 16, making it particularly suitable for applications with inclined surfaces. A mounting base 14 is mounted on the frame 12, which is slidably connected to it. The motor 2 is fixedly mounted on the mounting base 14, and a fore-aft adjustment mechanism is provided between the mounting base 14 and the frame 12. The fore-aft adjustment mechanism comprises a fore-aft adjustment screw 15, which is rotatably mounted on the mounting base 14 and threadedly connected to the frame 12. Since the mounting base 14 is slidably connected to the frame 12, rotating the fore-aft adjustment screw 15 adjusts the depth of the connection between the fore-aft adjustment screw 15 and the frame 12, thereby driving the fore-aft movement of the mounting base 14. The motor 2 on the mounting base 14 is connected to the grinding wheel shaft 5, thereby driving the grinding wheel 6 on the grinding wheel shaft 5 to move forward and backward, improving the performance of the device.

[0029] Working principle:

[0030] When in use, loosen the movable bracket 4 and move it upward, then insert the annular workpiece 16 from the grinding wheel shaft 5, then move the movable bracket 4 downward and tighten it, so that the sleeve 7 is slidably sleeved on the top of the grinding wheel shaft 5, and then adjust the angle and position through the horizontal adjustment mechanism and the front and rear adjustment mechanism to carry out the grinding operation.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
