[0023] A chuck 41 is provided on top of the workpiece mounting base 4, which is used to limit the position of the workpiece 17. The workpiece mounting base 4 is mounted on a slide 7. The workpiece mounting base 4 is slidably connected to the slide 7 in a first horizontal direction, and the slide 7 is slidably connected to the frame 1 in a second horizontal direction. The first and second horizontal directions are arranged perpendicularly.

[0024] Specifically, refer to Figure 3 The frame 1 is provided with a threaded rod 71 rotatably connected to the frame 1 and a rotary motor for driving the threaded rod 71 to rotate. The slide 7 is threadedly connected to the threaded rod 71, and the axis of the threaded rod 71 extends in the second horizontal direction. The rotary motor can drive the threaded rod 71 to rotate, thereby causing the slide 7 to move in the second horizontal direction.

[0025] Furthermore, two sets of first telescopic sleeves 72 are arranged between the frame 1 and the slide 7. The first telescopic sleeves 72 are connected to the frame 1 from the two sides of the slide 7 respectively. The part of the threaded rod 71 that is not connected to the slide 7 is wrapped by the first telescopic sleeve 72, thereby preventing the threaded rod 71 from being directly exposed to the working space 3 and reducing the impact of chips on the threaded rod 71.

[0026] refer to Figure 2 Two sets of horizontal telescopic assemblies 8 are provided between the workpiece mounting base 4 and the slide 7. The two sets of horizontal telescopic assemblies 8 are connected to the slide 7 from two sides of the workpiece mounting base 4. The horizontal telescopic assemblies 8 include a horizontal cylinder 81 and a second telescopic sleeve 82. The horizontal cylinder 81 is located inside the second telescopic sleeve 82.

The horizontal cylinder 81 is used to drive the workpiece mounting base 4 to move horizontally in a first direction on the slide 7. The horizontal cylinder 81 is enclosed within the interior of the second telescopic sleeve 82, thereby preventing the horizontal cylinder 81 from being directly exposed to the workspace 3 and reducing the impact of chips on the horizontal cylinder 81.

[0028] refer to Figure 3 The grinding wheel mounting base 15 is vertically slidably connected to the frame 1. Two sets of vertical telescopic assemblies 9 are provided between the grinding wheel mounting base 15 and the frame 1.
