DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0024] Reference Figure 1-Figure 6 A slip-on flange processing equipment for high vacuum sealing connection includes a platform 1, a grinding assembly is provided on the upper surface of the platform 1, a mounting groove is provided on the lower surface of the platform 1, a plurality of telescopic rods 2 are fixedly installed horizontally on the inner wall of the mounting groove in a circular shape, a U-shaped bearing plate 3 is fixedly installed at one end of the telescopic rod 2, a through hole is provided on the upper surface of the bearing plate 3, a hollow rod 4 is slidably installed in the through hole, a suction cup 5 is fixedly installed at the bottom end of the hollow rod 4, a mounting plate 6 is fixedly installed at the top end of the hollow rod 4, a sliding rod is symmetrically fixedly installed vertically on the upper surface of the bearing plate 3, and the mounting plate 6 is slidably sleeved on the two sliding rods, a through hole communicating with the hollow rod 4 is opened on the surface of the mounting plate 6, a rotating shaft 7 is sealed and rotatably installed in the through hole, an arc-shaped vent 8 is opened on the surface of the hollow rod 4, a covering plate 9 for covering the vent 8 is fixedly installed on one end of the rotating shaft 7 located in the hollow rod 4 through a connecting rod, and a fixing block is fixedly installed on the other end located outside, and the fixing block is connected to the mounting plate 6 through an elastic component. The elastic component includes a torsion spring 15 sleeved on the rotating shaft 7, and the two ends of the torsion spring 15 are fixedly connected to the fixing block and the mounting plate 6 respectively.

[0025] A mounting groove is provided on the surface of the platform 1, and a threaded rod 10 is vertically rotatably installed in the mounting groove. A slide plate 11 is threadedly sleeved on the threaded rod 10, and a plurality of L-shaped push rods 12 are fixedly installed on the upper surface of the slide plate 11 in a circular shape. An inclined plate 13 is fixedly installed on the surface of the load-bearing plate 3 through a connecting rod, and an inclined opening 14 is provided on the surface of the inclined plate 13. The bottom of the mounting groove is circularly provided with a plurality of through openings that are all connected to the mounting groove, and a plurality of push rods 12 respectively pass through the plurality of through openings, and one end is slidably arranged in the plurality of inclined openings 14 respectively.

[0026] The flange to be polished is placed between multiple supporting plates 3, and then the threaded rod 10 is rotated to control the slide plate 11 to move the multiple supporting rods 12 vertically, and the ends of the multiple supporting rods 12 will slide in the multiple bevels 14 respectively. When the multiple supporting rods 12 move up, the multiple telescopic rods 2 will be stretched together, and when the multiple supporting rods 12 move down, the multiple telescopic rods 2 will shrink together until the flange is clamped into the multiple supporting plates 3 and tightly against the inner wall of the supporting plates 3, the first fixation of the flange can be completed. At this time, the multiple hollow rods 4 are controlled to move down with the multiple suction cups 5 so that the suction cups 5 are tightly against the flange. The suction cups 5 are deformed by the pressure, and the gas in the suction cups 5 will slip out from the gap between the suction cups 5 and the flange contact surface, and then the flange is adsorbed. At this time, the second fixation of the flange is completed, and flanges of different sizes can be quickly fixed, which is very practical.

[0027] When it is necessary to release the fixation, first, by rotating the multiple rotating shafts 7, the multiple covering plates 9 are controlled to no longer cover the multiple vents 8 respectively, and the gas in the outside will enter the hollow rod 4 and the suction cup 5 from the vent 8, thereby automatically releasing the adsorption between the suction cup 5 and the flange. Then, after releasing the rotating shaft 7, the rotating shaft 7 will quickly rotate and reset with the covering plate 9 under the elastic potential energy of the torsion spring 15, and the covering plate 9 will cover the vent 8 again. Then, at this time, by rotating the threaded rod 10, the multiple push rods 12 are controlled to move downward, so that the multiple telescopic rods 2 are contracted together until the flange is moved out of the multiple bearing plates 3.

[0028] The grinding assembly includes an L-shaped plate fixedly mounted on the upper surface of the table body 1, a hydraulic cylinder 16 fixedly mounted on the upper surface of the L-shaped plate, a drive motor 17 fixedly mounted at the bottom end of the drive shaft of the hydraulic cylinder 16, and a grinding disc 18, and the grinding disc 18 is fixedly connected to the output shaft of the drive motor 17.

[0029] When the hydraulic cylinder 16 is started, the driving shaft of the hydraulic cylinder 16 will move vertically with the driving motor 17 and the grinding disc 18, and when the driving motor 17 is started, the grinding disc 18 will rotate.

[0030] A transmission component is provided in the placement groove, which is used to control the rotation of the threaded rod 10. The transmission component includes a rotating rod 19 vertically rotatably installed in the placement groove, two sprockets 20 and a chain 21 meshed and wound around the two sprockets 20. The two sprockets 20 are fixedly sleeved on the rotating rod 19 and the threaded rod 10 respectively.

[0031] By rotating the rotating rod 19, the threaded rod 10 will rotate together under the transmission action of the two sprockets 20 and the chain 21. The rotation of the threaded rod 10 can be controlled at a position close to the notch of the mounting groove, and there is no need to put the hand into the inner position of the mounting groove to rotate the threaded rod 10, which is more convenient.

[0032] A straight rod is vertically fixed in the installation groove, and a placement plate 22 is fixed on the top of the straight rod. When fixing the flange, the flange can be placed on the upper surface of the placement plate 22 first, and then the threaded rod 10 is rotated to control the stretching of multiple telescopic rods 2 so that the flange enters the multiple bearing plates 3 without having to hold the flange all the time.

[0033] In the utility model, the flange to be polished is placed between multiple bearing plates 3, and then the slide plate 11 is controlled to move vertically with multiple push rods 12 by rotating the threaded rod 10. The ends of the multiple push rods 12 will slide in the multiple bevels 14 respectively. When the multiple push rods 12 move up, the multiple telescopic rods 2 will be stretched together, and when the multiple push rods 12 move down, the multiple telescopic rods 2 will shrink together until the flange is clamped into the multiple bearing plates 3 and tightly against the inner wall of the bearing plates 3. At this time, the multiple hollow rods 4 are controlled to move down with the multiple suction cups 5, so that the suction cups 5 are tightly against the flange. The suction cups 5 are deformed by the pressing force, and the gas in the suction cups 5 will flow out from the gap between the suction cups 5 and the contact surface of the flange. When the flange is out, the flange is adsorbed. At this time, the fixing of the flange is completed, and flanges of different sizes can be quickly fixed. It is very practical. When it is necessary to release the fixation, first, by rotating the multiple rotating shafts 7, the multiple covering plates 9 are controlled to no longer cover the multiple vents 8 respectively, and the gas in the outside will enter the hollow rod 4 and the suction cup 5 from the vent 8, thereby automatically releasing the adsorption between the suction cup 5 and the flange. After the rotating shaft 7 is released, the rotating shaft 7 will quickly rotate and reset with the covering plate 9 under the elastic potential energy of the elastic component, and the covering plate 9 will cover the vent 8 again. Then, at this time, by rotating the threaded rod 10, the multiple push rods 12 are controlled to move downward, so that the multiple telescopic rods 2 are contracted together until the flange is moved out of the multiple bearing plates 3.

[0034] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
