[0025] According to this specific embodiment, the two robotic arms 2 are fixedly arranged on the top of the base 1; the two polishing devices 3 are respectively arranged on one side of the two robotic arms 2; one polishing device 3 is arranged on each robotic arm 2, and the robotic arm 2 drives the polishing device 3 to polish the end face of the end flange of the valve body.

[0026] Furthermore, the lifting support mechanism 4 is arranged on the base 1; the pressing mechanism 5 is arranged on the base 1; the left and right adjustment mechanism 6 is arranged on the base 1; the front and rear adjustment mechanism 7 is arranged on the left and right adjustment mechanism 6; the two mounting blocks 8 are respectively arranged on the front and rear adjustment mechanism 7; and the two locking rods 9 are respectively fixedly arranged on one side of the two mounting blocks 8.

The first screw rod 44 drives the connecting plate 45. The connecting plate 45 drives the support block 42 to rise and fall through multiple first guide rods 41, thereby adjusting the height position of the valve body supported by the support block 42.

[0033] In this embodiment, the two vertical plates 61 are used to fix the third guide rods 62, the two third guide rods 62 are used to slide the sliding seat 63, the driving member 65 is used to drive the second screw rod 64 to rotate, the second screw rod 64 drives the sliding seat 63 to slide in the left and right directions, and finally drives the two locking rods 9 to slide synchronously in the left and right directions.

[0034] Furthermore, the mounting seat 651 is fixedly arranged on the top of the base 1; the rotating shaft 652 is rotatably connected to the mounting seat 651 and passes through the mounting seat 651; the handle 653 is fixedly arranged on one side of the rotating shaft 652; the driving bevel gear 654 is fixedly arranged on one side of the rotating shaft 652; the driven bevel gear 655 is fixedly arranged on one side of the second screw rod 64 and meshes with the driving bevel gear 654.

[0037] In this embodiment, the first guide rail 71 is used to slide and install the two first sliders 72, and the first bidirectional screw rod 73 has two opposite threads. Therefore, rotating the first bidirectional screw rod 73 can drive the two first sliders 72 to slide in opposite directions in the front and rear directions, and finally drive the two locking rods 9 to move away from or closer to each other, which is used to adjust the front and rear positions of the two locking rods 9, and the second knob 74 is used to facilitate the rotation of the first bidirectional screw rod 73.

[0039] In this embodiment, the second guide rail 531 is used for slidingly installing the two second sliders 532, and the second bidirectional screw rod 533 has two opposite threads. Therefore, rotating the second bidirectional screw rod 533 can drive the two second sliders 532 to slide in opposite directions in the left and right directions, and finally drive the two pressing blocks 54 to move away from or approach each other, so that the two pressing blocks 54 can be suitable for valve bodies of different lengths; at the same time, when the two pressing blocks 54 are pressed down, the positions of the two pressing blocks 54 can be adjusted, so that the two pressing blocks 54 are respectively close to the flanges at both ends of the valve body, so that under the limitation of the two pressing blocks 54, the valve body is also stuck in the left and right directions, unable to move, and more stable; the motor 534 is used to drive the second bidirectional screw rod 533 to rotate.
