The flange 100 is a disc-shaped body, and the plurality of connection holes 200 are distributed at intervals along the circumference of the flange 100. These connection holes 200 penetrate the two end faces of the flange 100.

[0035] The polishing device in this utility model is mainly used to polish the outer peripheral wall of the flange 100.

[0036] Example 1

[0037] like Figures 2-3 As shown, this embodiment provides a surface polishing device for valve flanges, including: a base 5, a clamping plate 1, a fixing frame 2, a polishing component 3, and a rotary drive component 4.

[0038] The clamping plate 1 can clamp the end face of the flange 100. The clamping plate 1 can be equipped with a mechanical structure to clamp the flange 100, or it can be equipped with a pneumatic adsorption structure to adsorb and clamp the end face of the flange 100.

[0039] Please see Figure 3 The fixing frame 2 is located on one side of the clamping plate 1, and the base 5 is used to support the clamping plate 1 and the fixing frame 2. The clamping plate 1 can rotate on the base 5, and the fixing frame 2 is fixedly connected to the base 5.

[0040] The polishing part 3 is located on the side of the fixed frame 2 near the flange 100. The polishing part 3 can contact the outer peripheral wall of the flange 100 to polish the outer peripheral wall of the flange 100. The width of the polishing part 3 is greater than the thickness of the flange 100. The polishing part 3 can adjust the distance between itself and the fixed frame 2 in the radial direction of the flange 100.

[0041] The rotary drive 4 is used to drive the clamping disk 1 to rotate. The rotary drive 4 is also provided on the base 5. In the prior art, structures that can drive the clamping disk 1 to move in the circumferential direction, such as motors, can be used as the rotary drive 4 in this embodiment.

[0042] In this embodiment, the end face of the flange 100 is first clamped by the clamping plate 1, and then the distance between the polishing part 3 and the fixing frame 2 is adjusted so that the polishing part 3 contacts the outer peripheral wall of the flange 100. Then, the rotary drive 4 is started to drive the clamping plate 1 to rotate and drive the flange 100 to move in the circumferential direction, so that the polishing part 3 polishes the entire outer peripheral wall of the flange 100.

[0043] In this embodiment, since the distance between the polished part 3 and the fixed frame 2 is adjustable, it is convenient for the flange 100 to be placed and removed on the clamping plate 1.

[0044] The polishing device of this embodiment can first clamp the flange 100 and then polish the entire outer peripheral wall of the flange 100 efficiently. Moreover, the polishing process does not require the worker to get too close to the polishing device, which ensures good safety.

[0045] Example 2

[0046] This embodiment provides a surface polishing device for valve flanges. In addition to the technical solutions of the above embodiments, it also discloses a method of clamping flange 100 with clamping plate 1.

[0047] In this embodiment, a mechanical structure is used to clamp the flange 100. Please refer to [link / reference]. Figure 2 Multiple positioning pins 601 are provided circumferentially on the end face of the clamping disk 1 away from the rotary drive component 4. The number of positioning pins 601 is less than or equal to the number of connecting holes 200 on the flange 100. These positioning pins 601 can be inserted into the corresponding connecting holes 200 on the flange 100. A locking block 602 is provided at the end of the positioning pin 601 away from the clamping disk 1. The locking block 602 can restrict the axial movement of the flange 100 on the positioning pin 601.

[0048] Specifically, the outer wall of the positioning post 601 away from the clamping plate 1 is provided with external threads, and the locking block 602 is provided with a locking thread hole 6021, and the locking block 602 is threadedly connected to the positioning post 601. Figure 2The diagram shows that each positioning post 601 is provided with an external thread, and a corresponding locking block 602 is provided to each positioning post 601 for connection. It should be noted that external threads can also be provided on only one or two positioning posts 601 that are symmetrical to the center of the flange 100, and the corresponding locking blocks 602 can be used to connect these positioning posts 601. Although this slightly affects the locking effect of the flange 100, it can simplify the clamping operation of the flange 100 by the workers and improve the clamping efficiency.

[0049] Figure 4 The clamping method of this embodiment is shown to clamp the flange 100, in which the axial movement of the flange 100 on the positioning post 601 is restricted.

[0050] Example 3

[0051] This embodiment provides a surface polishing device for valve flanges. In addition to the technical solutions of the above embodiments, it also discloses a method for adjusting the distance between the polishing part 3 and the fixing frame 2.

[0052] In this embodiment, please refer to Figure 5 The polishing component 3 includes a mounting base 301 and an arc-shaped grinding plate 303. The arc-shaped grinding plate 303 is located on the side of the mounting base 301 near the flange 100. A guide groove 201 is provided on the surface of the fixing frame 2 near the mounting base 301. The mounting base 301 is slidably located in the guide groove 201 along the radial direction of the flange 100. An adjusting threaded hole 302 is provided on the mounting base 301. An adjusting screw 7 is rotatably provided on the fixing frame 2. The axis of the adjusting screw 7 coincides with the diameter of the flange 100. The threaded end of the adjusting screw 7 is threadedly connected to the adjusting threaded hole 302. Rotating the adjusting screw 7 can move the mounting base 301 in the axial direction of the adjusting screw 7, thereby driving the adjusting arc-shaped grinding plate 303 to move closer to and away from the flange 100.

[0053] In this embodiment, the arc-shaped grinding plate 303 is detachably connected to the mounting base 301. The arc-shaped grinding plate 303 can be any commercially available polishing material. The arc-shaped grinding plate 303 is a consumable. When the original arc-shaped grinding plate 303 can no longer be used, a new arc-shaped grinding plate 303 can be replaced, which provides good interchangeability and low operating costs. The surface of the arc-shaped grinding plate 303 near the flange 100 is adapted to the outer peripheral wall of the flange 100. The width of the arc-shaped grinding plate 303 is greater than the thickness of the flange 100. When the surface of the arc-shaped grinding plate 303 near the flange 100 contacts the outer peripheral wall of the flange 100, and the flange 100 moves in the circumferential direction, the arc-shaped grinding plate 303 can polish the outer peripheral wall of the flange 100.

[0057] When it is necessary to place the flange 100 onto the clamping plate 1 or remove the flange 100 from the clamping plate 1, first move the baffle 8 away from the flange 100 radially to facilitate the placement and removal of the flange 100. During the polishing process of the flange 100, move the baffle 8 closer to the flange 100 radially and cover the polished surface of the flange 100 with both baffles 8. This can block the debris generated during the polishing process, prevent debris from splashing, and facilitate the subsequent cleanup of the site by the workers.

[0058] Specifically, in this embodiment, a limiting frame 9 is provided on the fixed frame 2, and a limiting groove 901 is provided in the limiting frame 9. A connecting column 10 is provided on the baffle 8. The connecting column 10 is slidably connected to the limiting groove 901 along the radial direction of the flange 100.
