Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a novel welding fixture for boiler tube fittings. Background Technology

[0002] In the field of boiler manufacturing and maintenance, it is often necessary to weld two pipe fittings together at specific angles. The quality of this weld joint directly affects the safe operation of the boiler under high temperature and high pressure conditions. Current technology generally uses specialized fixed-angle tooling, designing and manufacturing a dedicated fixed welding fixture for each type of pipe fitting angle. However, it is worth considering that this approach has extremely poor versatility. The wide variety of boiler pipe fitting angle specifications necessitates the preparation of a large number of tooling fixtures, resulting in high costs, cumbersome management, and significant storage space requirements. It is also extremely unsuitable for non-standard angles or small-batch production tasks.

[0003] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a new type of welding fixture for boiler tubes, so as to solve the problem that the large number of boiler tube angle specifications leads to the need to prepare a large number of fixtures.

[0005] To achieve the above objectives, this utility model provides a novel welding fixture for boiler pipe fittings, including a base, a mounting bracket fixedly connected to the top of the base, a fixing block and a rotating block provided above the base, and a clamping mechanism for clamping the pipe fittings fixedly connected to both the fixing block and the rotating block. The fixed block and the mounting bracket are fixedly connected. A rotating bracket is fixedly connected to the bottom of the rotating block. A rotating locking component that cooperates with the rotating bracket is installed at the bottom of the fixed block. A support unit that cooperates with the rotating bracket is installed on the base.

[0006] Preferably, the support unit includes a support plate disposed above the base, the top of the support plate is in contact with the bottom of the rotating frame, the bottom of the support plate is provided with a threaded groove, a first lead screw is provided in the threaded groove, and the bottom end of the first lead screw is rotatably connected to the base, and a guide sleeve is fixedly connected to the support plate, and the guide sleeve is slidably sleeved on the outside of the mounting frame.

[0007] Preferably, the first lead screw is externally fixed with a fixing ring, the fixing ring having several limiting holes, a fixing frame is fixedly connected to the base, a limiting rod passes through the fixing frame, the limiting rod passes through the corresponding limiting hole, and a fixing plate located above the fixing frame is fixedly connected to the top of the limiting rod.

[0008] Preferably, the rotating locking component includes a first support portion fixedly installed at the bottom of the fixed block, a second lead screw fixedly connected through the first support portion, the second lead screw passing through the rotating frame, and two first nuts sleeved on the outside of the second lead screw, with the two first nuts respectively contacting the two sides of the rotating frame.

[0009] Preferably, the clamping mechanism includes an upper clamping plate and a lower clamping plate. A plug is fixedly connected to the bottom end of the lower clamping plate. Slots that cooperate with the plug are opened on both the fixed block and the rotating block. The plug is located in the corresponding slot. Second support parts are fixedly connected to both sides of the upper clamping plate. Third support parts are fixedly connected to both sides of the fixed block and the rotating block. A third lead screw is fixedly connected to the second support part. The third lead screw passes through the corresponding third support part. A second nut located below the third support part is sleeved on the outside of the third lead screw.

[0010] Preferably, anti-slip pads are fixedly connected to both the upper and lower clamping plates.

[0011] The beneficial effects of this utility model are as follows: Based on the required welding angles of the two pipe fittings, the operator drives the rotating frame to rotate relative to the fixed block, changing the position of the rotating block. The rotating frame is supported by a support unit and locked by a rotating locking component, thus fixing the rotating frame relative to the fixed block. The operator clamps the two pipe fittings to be welded using clamping mechanisms on the fixed block and rotating block, respectively. Then, the operator can operate the welding torch to weld the connection of the pipe fittings. This facilitates welding two pipe fittings at different angles. For non-standard parts, repair parts, or small-batch orders in the boiler industry, one set of tooling can cover multiple welding angles, greatly reducing the number of tooling pieces, lowering costs and warehousing pressure. This tooling makes undertaking such orders profitable and efficient. Attached Figure Description

[0017] This specification provides one or more embodiments of a novel boiler tube welding fixture, such as... Figure 1 As shown, it includes a base 1, a mounting bracket 2 is fixedly connected to the top of the base 1, a fixing block 3 and a rotating block 4 are provided above the base 1, and a clamping mechanism for clamping the pipe fitting is fixedly connected to both the fixing block 3 and the rotating block 4. The fixed block 3 and the mounting bracket 2 are fixedly connected. The bottom of the rotating block 4 is fixedly connected to the rotating bracket 5. The bottom of the fixed block 3 is equipped with a rotating locking component that cooperates with the rotating bracket 5. The base 1 is equipped with a support unit that cooperates with the rotating bracket 5. According to the angle that the two pipe fittings need to be welded, the operator drives the rotating bracket 5 to rotate relative to the fixed block 3, changing the position of the rotating block 4. The rotating bracket 5 is supported by the support unit and locked by the rotating locking component, so that the rotating bracket 5 is fixed relative to the fixed block 3. The operator clamps the two pipe fittings to be welded by the clamping mechanism on the fixed block 3 and the rotating block 4 respectively. Then the operator can operate the welding gun to weld the connection of the pipe fittings. It is convenient to weld two pipe fittings at different angles. For non-standard parts, repair parts or small batch orders in the boiler industry, one set of tooling can cover multiple welding angles. This greatly reduces the number of tooling, reduces costs and warehousing pressure. This tooling makes it profitable and efficient to undertake such orders.

[0018] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, the support unit includes a support plate 6 disposed above the base 1. The top of the support plate 6 contacts the bottom of the rotating frame 5. A threaded groove 9 is provided on the bottom of the support plate 6, and a first lead screw 8 is disposed in the threaded groove 9. The bottom end of the first lead screw 8 is rotatably connected to the base 1. A guide sleeve 7 is fixedly connected to the support plate 6, and the guide sleeve 7 is slidably sleeved on the outside of the mounting frame 2. A fixing ring 10 is fixedly sleeved on the outside of the first lead screw 8. Several limiting holes 11 are provided on the fixing ring 10. A fixing frame 12 is fixedly connected to the base 1, and a limiting rod 13 passes through the fixing frame 12. The limiting rod 13 passes through the corresponding limiting hole 11. The top of the limiting rod 13 is fixedly connected to a fixed plate 14 located above the fixed frame 12. The rotating locking component includes a first support part 15 fixedly installed at the bottom of the fixed block 3. A second lead screw 16 is fixedly connected through the first support part 15. The second lead screw 16 passes through the rotating frame 5. Two first nuts 17 are sleeved on the outside of the second lead screw 16, and the two first nuts 17 are in contact with the two sides of the rotating frame 5 respectively. The operator drives the two first nuts 17 to rotate so that the two first nuts 17 no longer clamp the rotating frame 5. The operator drives the rotating frame 5 and rotating block 4 to rotate relative to the first support part 15 and fixed block 3, changing the position of rotating block 4 and thus changing the included angle between the two clamping mechanisms. The operator drives the fixed plate 14 and limiting rod 13 to move upward, so that the limiting rod 13 disengages from the corresponding limiting hole 11, releasing the restriction on the position of the fixing ring 10 and the first lead screw 8. The operator drives the first lead screw 8 to rotate, and the first lead screw 8 drives the support plate 6 and guide sleeve 7 to move vertically relative to the mounting frame 2. Finally, the top of the support plate 6 contacts the bottom of the rotating frame 5, and the rotation is controlled by the support plate 6. The frame 5 and the rotating block 4 provide support to reduce the possibility of tilting and swaying of the rotating frame 5. Then, the operator drives the fixed plate 14 and the limiting rod 13 to move so that the limiting rod 13 passes through the corresponding limiting hole 11. The bottom of the fixed plate 14 and the top of the fixed frame 12 come into contact, limiting the position of the fixing ring 10 and the first lead screw 8, and preventing the fixing ring 10 and the first lead screw 8 from rotating and swaying due to non-human factors. The operator drives the two first nuts 17 to rotate so that the two first nuts 17 clamp the rotating frame 5, thereby fixing the rotating frame 5 and the rotating block 4 relative to the fixed block 3 and the base 1.

[0019] In embodiments of this utility model, such as Figure 1 and Figure 2As shown, the clamping mechanism includes an upper clamping plate 18 and a lower clamping plate 19. A plug 20 is fixedly connected to the bottom end of the lower clamping plate 19. Slots 21 that mate with the plug 20 are provided on both the fixed block 3 and the rotating block 4. The plug 20 is located within the corresponding slots 21. Second support parts 22 are fixedly connected to both sides of the upper clamping plate 18. Third support parts 23 are fixedly connected to both sides of the fixed block 3 and the rotating block 4. A third lead screw 24 is fixedly connected to the second support part 22, passing through the corresponding third support part 23. A second nut 25 located below the third support part 23 is sleeved on the outside of the third lead screw 24. Anti-slip pads 26 are fixedly connected to both the upper clamping plate 18 and the lower clamping plate 19. According to the specifications of the pipe fitting, select the appropriate upper clamping plate 18 and lower clamping plate 19. The operator drives the lower clamping plate 19 to move so that the insert 20 on the lower clamping plate 19 is inserted into the corresponding slot 21. Then the operator places the pipe fitting to be welded on the lower clamping plate 19. The operator then moves the upper clamping plate 18 above the pipe fitting, and the third screw 24 passes through the corresponding third support part 23. Then the operator rotates and sleeves the second nut 25 on the outside of the third screw 24. The top of the second nut 25 and the bottom of the third support part 23 are in close contact so that the upper clamping plate 18 and lower clamping plate 19 clamp the pipe fitting. The design of the anti-slip pad 26 reduces the possibility of the pipe fitting sliding relative to the upper clamping plate 18 and lower clamping plate 19.
