[0032] Example 3:

[0033] This utility model is as follows Figures 1-4 As shown, the fixed base 2 has a guide groove horizontally opened inside, and the guide groove is connected to the bottom of the adjusting base 303 through a guide block; an auxiliary plate is fixedly installed at the rear end of the adjustable top plate 9, and the front of the auxiliary plate is connected to the back of the protective frame 11 through a knob and a slide rail; connecting plates are fixedly installed on both sides of the top of the circular suction pipe 801, and the upper end of the connecting plate is connected to the side of the sliding plate 5.

[0034] Using the above technical solution, an auxiliary plate is installed at the rear end of the adjustable top plate 9. It is connected to the back of the protective frame 11 through the cooperation of the knob and the slide rail. The combination of the knob and the slide rail makes the adjustment of the adjustable top plate 9 simple and convenient. Operators can easily adjust the height and position of the adjustable top plate 9 according to the actual grinding needs. This flexible adjustment method can adapt to the grinding work of valve flanges of different sizes and shapes, greatly improving the versatility of the device.

[0035] The working principle of this utility model is as follows: First, the valve flange to be ground is placed on the fixed seat 2 at the top of the base 1. By utilizing the cooperation between the guide groove inside the fixed seat 2 and the guide block at the bottom of the adjusting seat 303, the adjusting seat 303 can be adjusted horizontally. By rotating the threaded rod 301 and its rotational connection with the adjusting seat 303, the position of the adjusting seat 303 can be further precisely adjusted.
