Description

Technical Field

[0001] The invention relates to the technical field of bellows valve production, in particular to a device for conveniently installing a high-strength spring of a bellows valve. Background Art

[0002] At present, bellows valves are widely used. Although diaphragm valves are cheap, the diaphragm is easily damaged due to the temperature being close to the upper limit of use. In the case of large-scale use, maintenance and replacement are complicated and expensive. Ordinary valve sealing materials cannot be applied to this working condition. However, in the process of assembling the bellows valve, due to the large size of the bellows valve, the spring strength used is relatively high, and manual assembly is difficult, so it is necessary to use a hydraulic press to compress the spring. Therefore, a tool is needed to locate the position of the bellows valve cylinder body to ensure that the hydraulic press presses vertically downward on the cylinder head. However, the existing auxiliary tools still require the staff to align the cylinder cavity with the cylinder head through visual observation. However, after alignment, it is difficult to ensure that the cylinder head does not deviate during the process of the hydraulic press pressing down the cylinder head. Once deviate occurs, the hydraulic press needs to be retracted and the alignment operation needs to be re-performed, resulting in low efficiency when installing high-strength springs on bellows valves.

The movable groove 603 is opened on both sides of the lifting groove 602. There are two lifting plates 604 and they are respectively installed in the two lifting grooves 602 by inserting and moving. There are two second rubber blocks 605 and they are respectively fixed and bonded to the top of the two lifting plates 604 near the center of the tooling cavity 302. There are two lifting shafts 606 and they are respectively fixed and installed on the two lifting plates 604 by bolts. At the bottom end, both ends of the lifting shaft 606 are respectively installed in the movable grooves 603 on both sides of the lifting groove 602 by being inserted and movably mounted. There are two limit rods 607, which are respectively fixed by bolts on the top of the two lifting grooves 602 away from the side of the middle of the tooling cavity 302; the limit rods 607 prevent the lifting plate 604 from rotating when it descends, and the second rubber block 605 clamps the cylinder head 412 to prevent the cylinder head 412 from rotating when it descends, so that the socket 413 is still aligned with the screw hole 312 during the descent.

[0040] Working principle: When the present invention is in use, first pull up the lifting plate 604. When the lifting shaft 606 follows the lifting plate 604 to rise to the top of the movable groove 603, rotate the lifting plate 604 so that the distance between the two second rubber blocks 605 is greater than the diameter of the cylinder cavity 311. Then rotate the rotating plate 304 so that the rotating plate 304 is in a vertical state. At this time, the limit block 309 is driven by the connecting frame 308 to move to the middle of the inner bottom end of the positioning groove 303. Then, the cylinder cavity 311 is placed into the tooling cavity 302. After the cylinder cavity 311 is completely placed, rotate the rotating plate 304 toward the inside of the tooling cavity 302 so that the rotating plate 304 is in a horizontal state. The first positioning head 306 faces downward, and the first positioning head 306 is squeezed into the first spring tube 305 by the top of the cylinder cavity 311. Then the cylinder cavity 311 is rotated. When the screw hole 312 rotates to the first positioning head 306, the first positioning head 306 is ejected by the first return spring 307. At this time, the cylinder cavity 311 is positioned. Then the rotating plate 304 is rotated in the opposite direction, and the limit block 309 is driven to move toward the direction of the cylinder cavity 311 through the connecting frame 308. When the rotating plate 304 is horizontal and the first positioning head 306 faces upward, the first rubber block 310 is close to the cylinder cavity 311, so that the cylinder cavity 311 is fixed. At this time, the positioning of the cylinder cavity 311 is completed;

[0041] Then, the lifting plate 604 is rotated to make the lifting plate 604 vertical, and the bottom end of the second rubber block 605 is placed on the top of the strap 601, and then the cylinder head 412 is placed on the positioning plate 401. During this process, the cylinder head 412 presses down the positioning plate 401 as a whole. When the positioning plate 401 descends, the lifting rod 508 is driven to descend in the support cylinder 507. When the bottom end of the positioning plate 401 contacts the top of the support cylinder 507, the positioning plate 401 stops descending. During this process, the lifting frame 409 is pressed down by the cylinder head 412, and the rack 410 is driven to descend at the same time by the lifting frame 409. When the rack 410 descends, it drives the gear 404 to rotate, so that the rotating shaft 40 2 follows the rotation of the gear 404, and drives the rotating frame 403 to rotate through the rotating shaft 402, so that the rotating frame 403 in a horizontal state rotates to a vertical state after the cylinder head 412 is placed on the positioning plate 401. At this time, the second positioning head 408 contacts the top of the cylinder head 412, so that the second positioning head 408 and the telescopic rod 406 are squeezed into the second spring cylinder 405, and then the cylinder head 412 is rotated. When the socket 413 rotates to the second positioning head 408, the second positioning head 408 pops into the socket 413. At this time, the positioning of the cylinder head 412 is completed, and the cylinder head 412 is clamped by the second rubber block 605, and the second rubber block 605 is used to prevent the cylinder head 412 from rotating during the descending process;

[0042] The push plate 506 is pushed, and the slider 504 is driven to move toward the second magnetic block 502 through the push rod 505, and the slider 504 is adsorbed by the magnetic force of the second magnetic block 502. At this time, the positioning plate 401 leaves the cylinder head 412, and the socket 413 and the screw hole 312 are in an aligned state. The hydraulic device 2 is started, and the cylinder head 412 is driven to descend through the hydraulic device 2, so that the bottom end of the cylinder head 412 contacts the cylinder cavity 311, and the hexagon socket bolt connecting the cylinder cavity 311 and the cylinder head 412 is rotated and inserted into the socket 413 and the screw hole 312. The connection between the cylinder head 412 and the cylinder cavity 311 is completed, and after the rotating plate 304 is rotated to a vertical state again, the first rubber block 310 no longer supports the cylinder cavity 311. At this time, the cylinder cavity 311 and the cylinder head 412 can be taken out of the tooling cavity 302 as a whole.
