Description

Technical Field

[0001] This utility model belongs to the field of metal valve processing technology, and specifically relates to a tool for facilitating the assembly of metal valves. Background Technology

[0002] A valve is a pipeline accessory used to open and close pipelines, control flow direction, and regulate and control the parameters of the transported medium. A valve typically consists of a valve body, valve cover, valve disc, and valve stem. Valve manufacturing requires fitting tools to fix the workpiece in the correct position for installation or inspection.

[0003] For example, patent CN218226277U discloses a valve processing fixture, which can fix the inner wall of the valve through two clamping components to reduce the area of ​​the valve obstructed by the clamping components, facilitate the processing and inspection of the valve, and well meet the needs of valve processing. The rotating component facilitates the rotation of the valve, which is beneficial for further processing and inspection.

[0004] When clamping metal valves, this assembly tool uses multiple electric telescopic rods to push multiple support plates against the inner wall of the valve for contact and fixation. However, since the support plates can only contact a portion of the inner ends of the valve, only a portion of the inner ends of the valve will be subjected to pressure during clamping. In this case, the two ends of the valve may deform due to uneven force, which will affect the quality of the valve. Utility Model Content

This tool aims to solve the problem that existing technologies use multiple electric telescopic rods to push multiple support plates against the inner wall of the valve for contact and fixation. However, since the support plates can only contact a portion of the inner two ends of the valve, the valve's inner two ends may only be subjected to pressure during clamping. This can lead to uneven force on both ends of the valve, causing deformation and affecting the valve's quality.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model, by setting up a mounting mechanism, places the left end of the metal valve to be processed on the outer left end of the left cone block, and then starts the first motor to rotate the second threaded rod, driving the right support plate to move to the left along the slide groove until the left end of the right cone block moves to contact the inner side of the right end of the metal valve. Then the first motor is turned off, which fixes the metal valve between the left cone block and the rotating rod. Since the outer sides of the left cone block and the rotating rod are in complete contact with the inner sides of the left and right ends of the metal valve at this time, the mounting tool can ensure that the left and right ends of the metal valve are evenly pressured when it is installed, thus avoiding deformation of the metal valve during processing and fixing.

[0019] This utility model, by setting up a drive unit, starts the second motor. When its output shaft rotates, it drives the drive gear to rotate, which in turn drives the driven gear to rotate, causing the rotating rod to rotate as well. This causes the metal valve clamped between the right and left cone blocks at the left end to rotate together, allowing the metal valve to be processed at other angles without disassembly, thus providing convenience for the processing of the metal valve.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This specific embodiment is a tool for facilitating the machining and assembly of metal valves, and its structural schematic diagram is shown below. Figures 1 to 3 As shown, the system includes a base 1, a left support plate 2 fixedly connected to the upper left end of the base 1, a right support plate 3 connected to the upper right end of the base 1, a mounting mechanism at the upper end of the base 1, and a first bearing 401 mounted on the upper end of the right support plate 3. A second bearing 402 is mounted on the upper end of the left support plate 2. A sleeve rod 403 is fixedly connected to the inner side of the second bearing 402. A spring 404 is fixedly connected to the left end of the inner side of the sleeve rod 403. A sliding rod 405 is fixedly connected to the right end of the spring 404. The sliding rod 405 is fixedly connected to... A left conical block 406 is provided. Limiting blocks 407 are fixedly connected to the upper and lower sides of the outer left end of the sliding rod 405. Limiting grooves are formed at the upper and lower ends of the inner side of the sleeve rod 403. The outer side of the sliding rod 405 is slidably connected to the inner side of the sleeve rod 403, and the outer side of the limiting block 407 is slidably connected to the inner side of the limiting groove. A first threaded rod 408 is fixedly connected to the left side of the sliding rod 405. A sliding hole is formed at the middle position of the left end of the sleeve rod 403 and the middle position of the left end of the connecting bracket 412. The outer side of the first threaded rod 408 is slidably connected to the inner side of the sliding hole. Therefore, when the sliding rod 405 slides along the inner side of the sleeve rod 403, the limiting block 407 on its outer side slides along the inner side of the limiting groove, and simultaneously the first threaded rod 408 slides along the inner side of the sliding hole.

[0028] The first threaded rod 408 is connected to a connecting ring 409 on its outer side. The first bearing 401 is fixedly connected to a rotating rod 410 on its inner side. The left end of the rotating rod 410 is fixedly connected to a right cone block 411. The upper left end of the left support plate 2 is fixedly connected to a connecting frame 412. The connecting ring 409 has an internal thread on its inner side. The outer side of the first threaded rod 408 is threadedly connected to the inner side of the connecting ring 409. The outer side of the connecting ring 409 abuts against the outer side of the connecting frame 412. By rotating the connecting ring 409 until the outer side of the first threaded rod 408 is located at the left and right ends of the connecting frame 412, the first threaded rod 408 and the connecting frame 412 can be relatively fixed.

[0029] Furthermore, when the right cone block 411 contacts the metal valve to the right of the left cone block 406, it generates a force that pushes the left cone block 406. At this time, the spring 404 will be compressed, which will buffer the metal valve and prevent it from being damaged by excessive pressure. Then, by rotating the two connecting rings 409 to the left and right ends of the connecting frame 412 outside the first threaded rod 408, the sliding rod 405 can be kept fixed, thereby ensuring that the left cone block 406 and the right cone block 411 are fixed during the processing of the metal valve and preventing the metal valve from shaking during processing.

[0030] In addition, an adjustment unit is provided at the lower end of the right support plate 3. The adjustment unit includes a first motor 501 installed on the right side of the base 1. The left end of the output shaft of the first motor 501 is fixedly connected to a second threaded rod 502. A third bearing 503 is installed inside the base 1. The outer sides of the left cone 406 and the right cone 411 abut against the inner sides of the left and right ends of the metal valve. A slide groove is provided at the upper right end of the base 1. The third bearing 503 is installed inside the base 1 at the middle position of the left end of the slide groove. A threaded hole is provided at the middle position of the lower end of the inside of the right support plate 3. The outer side of the second threaded rod 502 is threadedly connected to the inner side of the threaded hole. The outer side of the left end of the second threaded rod 502 is fixedly connected to the inner side of the third bearing 503. The lower outer side is slidably connected to the inner side of the slide groove. After the left end of the metal valve to be processed is placed on the outer left end of the left cone block 406, the second threaded rod 502 is rotated by starting the first motor 501, which drives the right support plate 3 to move to the left along the slide groove until the left end of the right cone block 411 moves to contact the inner side of the right end of the metal valve. Then the first motor 501 is turned off, which can fix the metal valve between the left cone block 406 and the rotating rod 410. Since the outer sides of the left cone block 406 and the rotating rod 410 are in complete contact with the inner sides of the left and right ends of the metal valve at this time, the tool can ensure that the left and right ends of the metal valve are evenly pressured when it is installed, thus avoiding deformation of the metal valve during processing and fixing.

[0031] Cooperate Figure 4A drive unit is provided at the outer end of the right support plate 3. The drive unit includes a second motor 601 installed on the upper right side of the right support plate 3. The output shaft of the second motor 601 is fixedly connected to the left end of the drive gear 602. The outer side of the rotating rod 410 is fixedly connected to the driven gear 603. The drive gear 602 and the driven gear 603 mesh. When the output shaft of the second motor 601 is started and rotates, it drives the drive gear 602 to rotate, which in turn drives the driven gear 603 to rotate, causing the rotating rod 410 to rotate together. This causes the metal valve held between the right cone block 411 and the left cone block 406 at the left end to rotate together, allowing the metal valve to be processed at other angle positions without disassembly, which provides convenience for the processing of the metal valve.

[0032] Working principle: When assembling a metal valve, first place the left end of the metal valve to be processed on the outer left end of the left cone block 406, then start the first motor 501 to make the second threaded rod 502 rotate, driving the right support plate 3 to move to the left along the slide groove until the left end of the right cone block 411 moves to the inner right end of the metal valve. Then turn off the first motor 501, which can fix the metal valve between the left cone block 406 and the rotating rod 410. Then rotate the two connecting rings 409 to the outer side of the first threaded rod 408 at the left and right ends of the connecting frame 412, so that the sliding rod 405 remains fixed, ensuring the metal valve is fixed during processing, completing the assembly of the metal valve, and then proceeding with the processing of the metal valve.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
