An inclined ladder 9 is fixedly connected to the upper surface of the workbench 10, and a storage box 12 is arranged below the inclined ladder 9. A conveyor belt 8 is arranged on the upper surface of the workbench 10, and a clamping assembly 7 is arranged on the upper surface of the workbench 10. The clamping assembly 7 includes a hollow bottom plate 23, and the hollow bottom plate 23 is arranged above the workbench 10. A groove 36 is opened inside the hollow bottom plate 23, and a cylinder 24 is fixedly connected to the lower surface of the hollow bottom plate 23.

[0025] Specifically, the design of the roller 27 allows the roller 27 to roll as the racks 25 on both sides slide, thereby reducing resistance and enabling the clamping assembly 7 as a whole to clamp the valve to be processed more quickly, thereby improving the overall transmission efficiency of the clamping assembly 7 and further improving production efficiency. Through the meshing transmission of the rack 25 and the gear 26, the support rod 34 and the clamping block 35 in the clamping assembly 7 can clamp the valve more firmly and conveniently.

[0026] Reference Figure 3 and Figure 4The output end of the cylinder 24 is fixedly connected with a fixed rod 37, one end of the fixed rod 37 is fixedly connected with a second connecting plate 39, the outer wall of the second connecting plate 39 is fixedly connected with a second positioning block 31, the outer wall of the second connecting plate 39 is fixedly connected with a support rod 34, one end of the support rod 34 is fixedly connected with a holding block 35, the outer wall of the support rod 34 is fixedly connected with a connecting strip 33, the outer wall of the connecting strip 33 is fixedly connected with a limiting frame 32, the inner wall of the limiting frame 32 is slidably connected with a rack 25, the inner wall of the limiting frame 32 is provided with a gear 26, the outer wall of the rack 25 is meshed with the outer wall of the gear 26, the outer wall of the gear 26 is rotatably connected to the upper surface of the hollow bottom plate 23, the outer wall of the rack 25 is provided with a roller 27, the lower surface of the roller 27 is rotatably connected with a U-shaped block 28, the lower surface of the U-shaped block 28 is fixedly connected with a first connecting plate 29, the outer wall of the first connecting plate 29 is fixedly connected with a first positioning block 30, and the inner wall of the first positioning block 30 is fixedly connected with a telescopic shaft 38.

[0027] Specifically, through the design of the driving wheel 15, the driven wheel 16 and the belt 19, the transmission effect is improved. At the same time, the electric push rod 20 in the grinding assembly 6 can adjust the position of the grinding wheel 22 according to the different inner diameter sizes of the valve body, making the device more flexible in practicality. The design of the electric slide rail 2 and the hydraulic cylinder 4 enables the grinding assembly 6 to accurately locate the position of the inner diameter of the valve body to be processed, thereby improving the grinding accuracy and ensuring the processing quality.

[0028] Working principle: When the inner cavity of the valve needs to be polished, the valve to be processed is placed on the conveyor belt 8. At this time, the valve is transported to the clamping assembly 7 through the conveyor belt 8. By starting the cylinder 24, the output end of the cylinder 24 drives the fixed rod 37 connected to it to move toward the middle, so that the left second connecting plate 39 connected to the fixed rod 37 also moves toward the middle, and the support rod 34 and the clamping block 35 on the second connecting plate 39 move accordingly. When the support rod 34 is pushed toward the middle, the connecting strip 33 connected to it pushes the limit frame 32 also moves toward the middle, and the rack 25 on one side of the limit frame 32 slides inward, driving the gear 26 to mesh and transmit, and the rack 25 on the other side of the gear 26 also transmits with it, thereby driving the support rod 34 and the clamping block 35 on the other side to advance toward the middle. While the racks 25 on both sides slide, the rollers 27 also roll accordingly, reducing the resistance, so that the overall clamping assembly 7 can clamp the valve to be processed faster. With the contraction of the telescopic shaft 38 inside the first positioning block 30 and the second positioning block 31, the clamping assembly 7 completes the clamping of the valve as a whole;

[0029] Secondly, after the valve to be processed is firmly fixed, the output end of the electric slide rail 2 is started, and the slider 3 slides on the electric slide rail 2 to adjust the lateral position of the grinding assembly 6. At the same time, the longitudinal height position of the grinding assembly 6 is adjusted by telescoping the output end of the hydraulic cylinder 4. After adjusting to a suitable processing position, the motor 13 in the grinding assembly 6 is started, so that the output end of the motor 13 drives the first rotating shaft 14 to rotate, thereby driving the driving wheel 15 connected thereto to rotate, and the belt 19 also rotates to drive the driven wheel 16 to rotate. The electric push rod 20 on the outer wall of the driven wheel 16 telescopes its output end according to the inner diameter size of the valve to be processed for adjustment, and the polishing wheel 22 polishes the inner cavity of the valve through the connecting rod 21 connected to the output end of the electric push rod 20. After the processing is completed, the polished valve is transported to the storage box 12 along the inclined ladder 9 via the conveyor belt 8.
