In the production and processing of the valve flange, in order to ensure the sealing when being connected with other components, the smoothness of the surface of the valve flange needs to be ensured during the final polishing, so that the smooth surface can make the gasket better adhere, reduce the risk of leakage, meanwhile, the smooth flange surface can reduce the fluid resistance, avoid impurities from adhering, and also improve the corrosion resistance and service life of the flange. Therefore, step-by-step polishing is needed during polishing, and the grit of the sandpaper is gradually increased for step-by-step polishing, which can effectively avoid damage to the flange surface, improve the polishing efficiency, obtain a uniform surface, and prevent the sandpaper from being blocked.

[0053] As shown, Figures 1-18 The layer adjusting mechanism 9 comprises a connecting fixed ring 901 rotatably connected at the top of the guide stabilizing ring 7, the bottom of the connecting fixed ring 901 is fixedly connected with a connecting support rod 902, a plurality of adjusting tooth rings 903 are arranged between the plurality of connecting support rods 902, a plurality of arc-shaped grooves corresponding to the connecting support rods 902 are formed in the guide stabilizing ring 7, after completing the polishing once and resetting the two arc-shaped clamping rods 304 and the overall polishing mechanism 4, and the flange support is removed, the connecting fixed ring 901 is rotated to drive the plurality of adjusting tooth rings 903 to rotate through the plurality of connecting support rods 902, the rotating adjusting tooth rings 903 push the plurality of triangular adjusting blocks 608, and then drive the overall layer rotating block 607 to rotate, so that the layer rotating block 607 can be retracted, the flange can continue to fall, and the next polishing step can be realized.

[0054] The working principle of the embodiment is as follows: when in use, the flange is sleeved on the top of the overall device from the guide stabilizing ring 7, then is lowered along the outer wall of the top layer support mechanism 6, and slowly descends under the limiting friction of the plurality of second rubber strips 611 until contacting the plurality of layer rotating blocks 607 in the top layer support mechanism 6, then the plurality of layer support mechanisms 6 are kept stationary, the manual steering frame 802 is rotated to drive the transmission rod 801 and the plurality of first threaded sleeves 803 and the plurality of second threaded sleeves 804 to rotate, the first threaded sleeves 803 are lowered and the second threaded sleeves 804 are raised through the spiral rotation of the corresponding cross-shaped threaded sleeves 805, and the lifting is performed under the limiting of the plurality of limiting sliding blocks 809, the corresponding limiting inclined blocks 603 are pushed through the T-shaped inclined blocks 808 on the plurality of top driving rings 806 and the plurality of bottom driving rings 807, the plurality of sliding expansion supporting blocks 602 are expanded outward, and finally the flange is expanded and supported;

[0055] Then the two second motor assemblies 302 drive the rotation of the corresponding transmission lead screws 303, and the transmission lead screws 303 with opposite screw structures drive the two arc-shaped clamping rods 304 to move close to each other, the clamping of the limiting bearing ring 504 is realized, and at the same time, the polishing mechanism 4 on the same side is moved as a whole through the plurality of driving connecting rods 409 when the arc-shaped clamping rod 304 moves, when the arc-shaped clamping rod 304 completes clamping, the polishing sandpaper 404 at the corresponding position on the top is clamped on one side of the flange, at this time, the first motor assembly 206 drives the transmission gear 207 to rotate, and then drives the inner tooth ring 505 engaged with the transmission gear 207, the rotation of the rotating ring 503 in the rotating support ring seat 501 is realized, and then the plurality of layer support mechanisms 6 are rotated, the corresponding expansion driving mechanism 8 and the layer adjusting mechanism 9 are rotated, and at the same time, the third motor assembly 406 drives the second belt pulley 407 to rotate, and then drives the first belt pulley 405 through the two transmission belts 408 to drive the rotating hollow column 403, and the polishing sandpaper 404 rotates in the opposite direction of the flange;

[0056] After the polishing is completed and the rotation is stopped, the second motor assembly 302 drives the two arc-shaped clamping rods 304 and the overall polishing mechanism 4 to reset, keeps the plurality of layer support mechanisms 6 stationary, reversely rotates the transmission rod 801 to release the expansion of the flange, then rotates the connecting fixed ring 901 to drive the plurality of adjusting tooth rings 903 to rotate through the plurality of connecting rods 902, as Figure 17 and 18, the rotating adjusting tooth ring 903 will push the plurality of triangular adjusting blocks 608, thereby driving the overall partition rotating block 607 to rotate, at this time, the plurality of partition rotating blocks 607 retract, the flange continues to slowly descend under the friction of the plurality of second rubber strips 611, and the flange is released from the connection and fixing ring 901 when it descends beyond the partition rotating block 607, under the elastic force of the plurality of first torsional springs 606 and second torsional springs 609, the corresponding partition rotating block 607 and triangular adjusting block 608 are reset respectively, thereby pushing the overall partition adjusting mechanism 9 to reset through the clamping of the triangular adjusting block 608 and the adjusting tooth ring 903, at this time, the plurality of partition rotating blocks 607 pop out again, and the flange polished once falls on the plurality of partition rotating blocks 607 in the next partition support mechanism 6;

[0057] At this time, continue to add the flange from the top guiding and stabilizing ring 7, the flange polished once again goes through the above steps, is polished by the polishing sandpaper 404 in the middle part, so that the flange is polished in turn under different mesh polishing sandpapers 404, finally slowly slides on the storage limiting sleeve 205 under the friction of the plurality of second rubber strips 611, and gradually accumulates, when a certain number is accumulated, the bottom hydraulic lifting assembly 204 drives the storage limiting sleeve 205 to descend when the rotating connection mechanism 5 is clamped by the arc-shaped clamping rod 304, and the storage limiting sleeve 205 and the plurality of limiting insertion rods 502 are disengaged from the limiting, the hydraulic translation assembly 202 controls the movement of the moving base plate 203, thereby moving the next empty storage limiting sleeve 205 to the directly below the overall rotating connection mechanism 5, and completing the clamping of the storage limiting sleeve 205 and the plurality of limiting insertion rods 502 by the hydraulic lifting assembly 204, thereby realizing the continuous polishing work, and the storage limiting sleeve 205 full of flanges polished can be disassembled and taken down, so as to realize the continuous polishing work and improve the polishing efficiency.

[0058] The above merely describes the preferred embodiment of the present application, but is not used to limit the protection scope of the present application.
