[0035] The fixing seat 210 is a cylinder with a hollow interior and an open top, and is fixed on the workbench 100 . A support plate 221 is positioned inside the fixing seat 210 .

[0036] The positioning ring 220 is fixed on the outer ring surface of the fixing seat 210, and the positioning ring 220 is fixed to the support plate 221 through the connecting plate 2211; the fixing plate 230 is a circular ring body, and it is fixed on the support plate 221, the fixing plate 230 can contact with the outer ring surface of the flange, and the positioning ring 220 can be received in the fixing seat 210;

[0037] The fixing column 240 is fixed at the middle of the workbench 100 , and a second clamping plate 241 is fixed on the fixing column 240 . The second clamping plate 241 can contact with the inner annular surface of the flange, and the second clamping plate 241 can be received in the fixing column 240 .

[0038] It is easy to understand that when grinding the outer annular surface of the flange, the inner diameter of the flange is clamped on the second clamping plate 241, and the second clamping plate 241 fixes the flange through friction. When grinding the inner annular surface of the flange, the second clamping plate 241 is stored in the fixed seat 210, and then the fixed plate 230 is moved up. The flange is fixed by the fixed plate 230, and it can be positioned when grinding the inner or outer annular surface of the flange in a tooling to ensure stability in use.

[0039] Specifically, if Figures 1 to 9 As shown, the side of the fixing seat 210 is provided with a plurality of positioning holes 212, and the positioning ring 220 is provided with a plurality of openings parallel to the positioning holes 212;

[0040] The positioning ring 220 is fixed on the fixing seat 210 via a U-shaped positioning frame 222 , and the positioning frame 222 passes through the opening of the positioning ring 220 and extends into the positioning hole 212 .

[0041] It is easy to understand that the positioning frame 222 is provided to facilitate positioning of the positioning ring 220 .

[0042] Specifically, if Figures 1 to 9 As shown, a reserved groove 211 is opened on the fixing seat 210, and the connecting plate 2211 extends into the reserved groove 211. The length of the reserved groove 211 is not greater than the height of the fixing seat 210, and the difference is within the range of 2 cm to 3 cm.

[0043] It is easy to understand that by sliding the positioning ring 220 down to the bottom of the reserved groove 211 , the fixing plate 230 can be received in the fixing seat 210 .

[0044] Specifically, if Figures 1 to 9 As shown, there are four reserved slots 211 , and a positioning hole 212 is respectively provided at the top and the bottom of each reserved slot 211 . A positioning frame 222 is fixed at each reserved slot 211 .

[0045] It is easy to understand that when the fixing plate 230 is received in the bottom of the fixing seat 210, the positioning ring 220 is fixed by the positioning frame 222, so that it can be fixed in place, which is convenient for equipment transportation or handling and is not easy to fall.

[0046] Specifically, if Figures 2 to 6 As shown, there are two cylinders 1 231 on the inner ring surface of the fixing plate 230 , the two cylinders 1 231 are parallel, and a clamping plate 1 232 is fixed to the output end of each cylinder 1 231 , and there is a gap between the two clamping plates 1 232 .

[0047] It is easy to understand that the cylinder 231 can drive the clamping plate 232 to move, so as to facilitate the positioning of the outer ring surfaces of flanges of various specifications.

[0048] Specifically, if Figures 1 to 9 As shown, a reserved cavity 244 with a “⊥”-shaped cross section is opened in the fixing column 240, and the second clamping plate 241 is a cylindrical structure composed of two arc-shaped plates, and a metal plate 2411 is fixed to the bottom of the second clamping plate 241;

[0049] A magnet block 2401 is fixed on the top of the reserved cavity 244 . The magnet block 2401 is a circular ring and can attract the metal plate 2411 with magnetic force.

[0050] It is easy to understand that the metal plate 2411 can be positioned by the magnet block 2401 , so that the second clamping plate 241 is firmly positioned on the fixing column 240 .

[0051] Specifically, if Figures 2 to 9As shown, an elastic element 245 is fixed in the reserved cavity 244, and the elastic element 245 is preferably a spring, and can also be other components that can expand and contract autonomously. A metal ring 247 is positioned at the top of the reserved cavity 244, and the magnet block 2401 can magnetically attract the metal ring 247. After the clamping plate 241 moves down to the reserved cavity 244, the clamping plate 241 can be positioned by the metal ring 247 to prevent the clamping plate 241 from popping up.

[0052] It is easy to understand that the second clamping plate 241 is moved downward to move the metal plate 2411 away from the magnet block 2401, and at the same time the elastic element 245 is compressed until the second clamping plate 241 is completely moved downward into the reserved cavity 244, and then the metal ring 247 is positioned in the magnet block 2401, so as to achieve the positioning of the second clamping plate 241.

[0055] It is easy to understand that the second clamping plate 241 can be driven to move by the second cylinder 243, so as to facilitate the positioning of the inner ring surface of flanges of various specifications.

[0056] In the above embodiment, when grinding the outer ring surface of the flange, the positioning ring 220 is stored in the fixing seat 210, the metal ring 247 is removed, the elastic element 245 releases the elastic potential energy, the clamping plate 241 is ejected upward, and the metal plate 2411 is positioned by the magnet block 2401, and then the inner diameter of the flange is clamped on the clamping plate 241, and the cylinder 243 is started to drive the clamping plate 241 to expand outward to clamp and fix the flange, and at the same time, the end face of the flange is fixed to the fixing column 2 40 contact, convenient for grinding the outer ring surface of the flange. When grinding the inner ring surface of the flange, first store the clamping plate 241 into the reserved cavity 244, use the metal ring 247 to position the clamping plate 241, then move the fixing plate 230 upward, fix the positioning ring 220 through the positioning frame 222, start the cylinder 1 231 to drive the clamping plate 1 232 to position the outer ring surface of the flange, so that the inner or outer ring surface of the flange can be positioned in one tooling to ensure stability in use.

[0057] In some embodiments of the present application, Figures 2 to 9As shown, an elastic membrane 242 with a cross-section of an inverted cone is fixed between the fixed block 2412 and the clamping plate 241, which is convenient for collecting grinding debris. At the same time, the elastic membrane 242 can extend along with the movement of the clamping plate 241 without affecting the movement of the clamping plate 241. A collection bag 246 is detachably connected to the metal plate 2411, and the debris falls into the collection bag 246 along the elastic membrane 242.

[0058] In the above embodiment, the debris generated by grinding can fall into the collection bag 246 along the elastic membrane 242. When there are a lot of debris in the collection bag 246, the collection bag 246 can be disassembled, the debris in the collection bag 246 can be cleaned, and then the collection bag 246 can be fixed in the metal plate 2411.
