Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a laser processing device for titanium-nickel coils. Background Technology

[0002] Titanium-nickel coils are high-performance metal tubing that combines the properties of titanium and nickel. They are widely used in chemical, petroleum, and metallurgical industries. During the welding process of titanium-nickel coils, laser welding rapidly melts the material using a high-energy beam, achieving micron-level weld precision. This method is particularly suitable for the thin-walled structure and complex shape of titanium-nickel coils.

[0003] To improve heat exchange efficiency, existing titanium-nickel coils often employ a thin-walled design. However, during welding, due to the thin-walled nature of the titanium-nickel coils, they are prone to deformation and torsion due to heat. This deformation not only alters the coil's pitch and diameter, affecting subsequent installation accuracy, but also increases the risk of burn-through and perforation during welding, impacting the sealing performance of the finished titanium-nickel coil.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1.

This keeps the position of the coil stable during welding, which helps to reduce welding errors. Furthermore, clamping and fixing the coil reduces the risk of deformation and torsion during welding, thereby effectively improving welding accuracy. 2. This solution uses components such as support rods and extrusion rods to drive the coil in a circular motion. During the rotation of the coil, the position of the coil and the extrusion rod remains stable, avoiding the need for full clamping of the coil. This effectively reduces the workload of clamping the coil multiple times, and while ensuring processing accuracy, it can also improve the welding efficiency of the coil to a certain extent. 3. This solution, by setting up a support component, can keep different positions on the underside of the coil flat through the brackets.

The two sets of brackets can limit the frame, thereby preventing the coil from sliding on the bracket surface, thus effectively improving the clamping stability of the coil. 4. This solution uses an adjustment component. The contact plate, which contacts the outer surface of the coil, can limit the movement of the coil. By changing the position of the contact plate, the pitch of the coil can be adjusted, thereby reducing the probability of deformation of the coil during welding and helping to maintain the pitch of the coil within an appropriate range.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 9The present invention provides a technical solution: A laser processing device for titanium-nickel coils includes a worktable 11, a frame 20, and a coil 19. A movable frame 13 and a fixed frame 15 are detachably connected to the upper outer surface of the worktable 11. A support rod 21 is rotatably connected to the outer surface of the movable frame 13. An expansion assembly is provided on the outer side of the support rod 21. The expansion assembly includes a mounting seat 18 fixedly connected to the outer surface of the support rod 21. A movable seat 23 is slidably connected to the outer surface of the support rod 21. Both the mounting seat 18 and the movable seat 23 have hinges on their outer sides. A swing rod 26 is movably connected to the mounting seat 18 and the movable seat 23 through the hinges. A second pin 27 is rotatably connected to the side of the swing rod 26 away from the support rod 21. A compression rod 28 for expanding and supporting the coil 19 is rotatably connected to the outer surface of the second pin 27.

[0021] The hinge part includes a mounting groove 24 embedded in the outer surface of the mounting base 18 and the movable base 23. A pin 25 is fixedly connected to the inner surface of the mounting groove 24. The outer surface of the pin 25 is rotatably connected to the swing rod 26. A locking sleeve 22 is threadedly connected to the outer surface of the support rod 21. The locking sleeve 22 is in contact with the outer surface of the movable base 23. A clamp 17 for clamping and fixing the support rod 21 is provided on the upper outer surface of the movable frame 13.

[0022] The number of swing rods 26 is several and arranged in a ring array. The outer surface of the extrusion rod 28 is in contact with the inner ring of the coil 19. The coil 19 has a spiral structure. A welding module 16 is provided on the upper side of the workbench 11. A positioning hole 12 is provided through the upper outer surface of the workbench 11. The number of positioning holes 12 is several and arranged in a parallel array. An adjustment rod 14 is rotatably connected to the outer surface of the movable frame 13 and the fixed frame 15. The lower side of the adjustment rod 14 is threadedly connected to the positioning hole 12 on the surface of the workbench 11. The welding module 16 is used to perform welding processing between the coil 19 and the frame 20.

[0023] By adopting the above technical solution, when laser welding is performed between the titanium-nickel coil 19 and the frame 20, the coil 19 is first sleeved on the outside of the support rod 21. The fixed frame 15 is used to support one end of the support rod 21. Then, the movable frame 13 is moved to the other end of the support rod 21, and the other end of the support rod 21 is supported by the movable frame 13. Then, by turning the adjusting rod 14, the fixed frame 15 and the movable frame 13 can be clamped and fixed through the threaded connection of the adjusting rod 14 to the positioning rod, so that the position of the fixed frame 15 and the movable frame 13 remains stable. Then, the support rod 21 can be clamped and fixed by the clamp 17 cooperating with the movable frame 13. The position of the support rod 21 is stabilized by rotating the locking sleeve 22. The locking sleeve 22 is screwed to the outer surface of the support rod 21. As the locking sleeve 22 rotates, it moves along the axis of the support rod 21. During the movement, the locking sleeve 22 pushes the movable seat 23. The mounting groove 24 on the surface of the mounting seat 18 and the movable seat 23 is used to fix the pin 25. As the distance between the movable seat 23 and the mounting seat 18 gradually decreases, the swing rod 26 will rotate around the pin 25 as the fulcrum. The angle between the swing rod 26 and the support rod 21 will gradually increase. At this time, the swing rod 26... The extrusion rods 28 are moved away from the support rods 21 by the second pin 27. During the synchronous movement of several sets of extrusion rods 28, they come into contact with the inner wall of the coil 19. The extrusion rods 28 can apply a certain outward tension to the coil 19, thereby keeping the position of the coil 19 stable during the welding process, which helps to reduce welding errors. Furthermore, by clamping and fixing the coil 19, the risk of deformation and torsion of the coil 19 during the welding process can be reduced, thus effectively improving the welding accuracy. Then, the frame 20 is placed on the upper side of the coil 19, and the welding module 16 is used to weld the coil 19 and the frame 20. Precision welding is performed. After a set of frames 20 is welded, the clamp 17 on the upper side of the movable frame 13 is loosened, and then the support rod 21 is rotated. The support rod 21 drives the swing rod 26 and the pressing rod 28 to rotate through the mounting base 18 and the movable base 23. Thus, the coil 19 can be driven to make a circular motion through the pressing rod 28. During the rotation of the coil 19, the position of the coil 19 and the pressing rod 28 remains stable, avoiding full clamping of the coil 19. This effectively reduces the workload of clamping the coil 19 multiple times, and improves the welding efficiency of the coil 19 to a certain extent while ensuring the processing accuracy.

[0024] Specifically, such as Figure 2 , Figure 5 and Figure 8As shown, a lifting assembly is provided on the upper side of the workbench 11. The lifting assembly includes a support base 29 fixedly connected to the upper outer surface of the workbench 11. A guide plate 37 is fixedly connected to the upper outer surface of the support base 29. A guide plate 39 is slidably connected to the inner surface of the guide plate 37. A top seat 33 is fixedly connected to the upper outer surface of the guide plate 39. A bracket 30 is fixedly connected to the upper outer surface of the top seat 33.

[0025] The number of top seats 33 and brackets 30 are two sets and symmetrically distributed. The outer surface of each bracket 30 is arc-shaped. A support plate 31 is fixedly connected between the two sets of brackets 30. The support plate 31 is used to support the frame 20. The upper outer surface of the support plate 31 is in contact with the outer surface of the coil 19.

[0026] By adopting the above technical solution, after the coil 19 is placed outside the extrusion rod 28, a support assembly is set up to reduce the risk of the coil 19 sagging due to gravity. The support base 29 slides and supports the guide plate 29 through the guide plate 1 37. The guide plate 2 39 is used to support the top seat 33. The top seat 33 supports the bracket 30. After the coil 19 is sleeved outside the extrusion rod 28, the bracket 30 can support the lower side of the coil 19. The bracket 30 can keep the lower side of the coil 19 flat at different positions. This can not only effectively reduce the probability of the coil 19 shaking and shifting during welding, but also keep the curvature of the coil 19 stable, thereby further improving the welding processing accuracy. The support plate 31 between the two sets of brackets 30 is used to support the frame 20. The two sets of brackets 30 can limit the frame 20, thereby preventing the coil 19 from sliding on the surface of the bracket 30, thus effectively improving the clamping stability of the coil 19.

[0027] Specifically, such as Figure 6 and Figure 9 As shown, an adjustment assembly is provided on the inner side of the bracket 30. The adjustment assembly includes baffles 40 fixedly connected to the left and right ends of the bracket 30. A drive rod 41 is rotatably connected between the two sets of baffles 40. A traction seat 42 is helically connected to the outer surface of the drive rod 41. A movable groove 49 is provided through the outer surface of the bracket 30. A connecting block 47 is slidably connected to the inner side of the movable groove 49.

[0028] A contact plate 46 is fixedly connected to the outer surface of the connecting block 47. The outer surface of the contact plate 46 is arc-shaped. The contact plate 46 contacts the outer surface of the coil 19. There are several groups of contact plates 46 arranged in a ring array. A sliding rod 48 is fixedly connected to the inner surface of the movable groove 49. The sliding rod 48 passes through both ends of the connecting block 47 and slides in contact with the connecting block 47. A rotating shaft 43 is fixedly connected to the inner surface of the traction seat 42. A traction rod 44 is rotatably connected to the outer surface of the rotating shaft 43. A rotating shaft 45 is rotatably connected to the end of the traction rod 44 away from the rotating shaft 43. The rotating shaft 45 is located inside the connecting block 47 and is fixedly connected to the connecting block 47. There are two groups of swing rods 26 arranged symmetrically. There are several groups of traction seats 42 arranged in a parallel array.

[0029] A positioning plate 51 is fixedly connected between the two sets of baffles 40. A positioning groove 50 is provided through the outer surface of the positioning plate 51. A positioning shaft 52 is fixedly connected to the outer surface of the traction rod 44. The positioning shaft 52 is located inside the positioning groove 50 and slides in contact with the positioning groove 50.

[0030] By adopting the above technical solution, in order to keep the pitch of the coil 19 within a predetermined range during the welding process, an adjustment component is set up. The movable groove 49 on the surface of the bracket 30 is used to slide the connecting block 47. The sliding rod 48 inside the movable groove 49 can guide the connecting block 47, so that the connecting block 47 can slide linearly inside the movable groove 49. The bracket 30 supports the drive rod 41 through the baffle 40. The drive rod 41 can support the traction seat 42. The traction seat 42 supports the traction rod 44 through the rotating shaft 43, so that the traction rod 44 can rotate around the rotating shaft 43. The connecting block 47 is used to fix the contact plate 46. The contact plate 46 can limit the coil 19 by contacting the outer surface of the coil 19. When fine-tuning the pitch of the coil 19, the operator rotates the drive rod 41, and the traction seat 47... 2. The drive rod 41 is connected to the drive rod 41 by a screw drive. As the drive rod 41 rotates, it moves along its axis. When the traction seat 42 moves a small distance, the traction rod 44 will rotate around the positioning shaft 52 as a fulcrum, thereby adjusting the distance between the two adjacent sets of connecting blocks 47. As the traction seat 42 continues to move, it will pull the traction rod 44 through the rotating shaft 43 during the movement. The positioning shaft 52, together with the positioning groove 50 on the surface of the positioning plate 51, can limit the swing rod 26. The traction seat 42 will pull the connecting block 47 through the swing rod 26, thereby driving the contact plate 46 to move synchronously through the connecting block 47. This allows the pitch of the coil 19 to be adjusted by the change in the position of the contact plate 46, thereby reducing the probability of deformation of the coil 19 during the welding process and helping to keep the pitch of the coil 19 within an appropriate range.

[0031] Specifically, such as Figure 5 and Figure 8 As shown, a buffer assembly is provided between the support base 29 and the top base 33. The buffer assembly includes a guide groove 36 that passes through the outer surface of the guide plate 2 39. A rotating rod 32 is rotatably connected to the outer surface of the guide plate 1 37. The rotating rod 32 passes through the left and right ends of the guide plate 2 39 through the guide groove 36. A cam 35 is fixedly connected to the outer surface of the rotating rod 32.

[0032] The upper outer surface of the support base 29 has an embedded slot 34, the cam 35 is located inside the slot 34, the outer surface of the cam 35 is in rotatable contact with the lower outer surface of the top seat 33, the outer surface of the rotating rod 32 is threadedly connected to a limit sleeve 38, and the limit sleeve 38 is in rotatable contact with the outer surface of the guide plate 37.

[0033] By adopting the above technical solution, in order to support coils 19 of different diameters, a buffer assembly is set between the support base 29 and the top base 33. The guide plate 37 is used to support the rotation of the rotating rod 32. When adjusting the height of the bracket 30, the operator first loosens the limiting sleeve 38, so that the limiting sleeve 38 is no longer in contact with the outer surface of the guide plate 39. Then, the rotating rod 32 is rotated, which drives the cam 35 to rotate synchronously. The outer surface of the cam 35 rotates into contact with the lower surface of the top base 33. When the cam 35 rotates to different angles, different positions on the surface of the cam 35 will contact the top base. When the top seat 33 and the rotating rod 32 come into contact, the distance between them will be adjusted accordingly. The guide groove 36 on the surface of the guide plate 37 can play a limiting role, so that the sliding between the guide plate 37 and the guide plate 39 is more stable. After the distance between the top seat 33 and the support seat 29 is adjusted to an appropriate range, the operator rotates the limiting sleeve 38 in the opposite direction to keep the position of the rotating rod 32 and the cam 35 stable. By flexibly adjusting the height of the bracket 30, it can play a supporting and limiting role for the coils 19 at different positions, thereby effectively improving the functionality and flexibility of the laser processing device.

[0034] Working principle: When laser welding is performed between the titanium-nickel coil 19 and the frame 20, the coil 19 is first fitted onto the outside of the support rod 21. The mounting grooves 24 on the surfaces of the mounting seat 18 and the movable seat 23 are used to fix the pin 25. As the distance between the movable seat 23 and the mounting seat 18 gradually decreases, the angle between the swing rod 26 and the support rod 21 gradually increases. The pressing rod 28 can apply a certain outward tension to the coil 19, thereby keeping the position of the coil 19 stable during the welding process. After the coil 19 is fitted onto the outside of the pressing rod 28, the bracket 30 can support the lower side of the coil 19. The bracket 30 can keep different positions on the lower side of the coil 19 flat. When the cam 35 rotates to different angles, different positions on the surface of the cam 35 will contact the top seat 33. At this time, the top seat 33 and the rotating rod 32 are in contact. The distance will be adjusted accordingly, which can support and limit the coils 19 at different distances. The connecting block 47 is used to fix and support the contact plate 46. The contact plate 46 can limit the coil 19 by contacting the outer surface of the coil 19. As the drive rod 41 rotates, it will move along its axis. When the traction seat 42 moves a small distance, the traction rod 44 will flip around the positioning shaft 52 as the fulcrum, thereby adjusting the distance between the two adjacent sets of connecting blocks 47. Then the frame 20 is placed on the upper side of the coil 19. The welding module 16 is used to perform precise welding between the coil 19 and the frame 20. The extrusion rod 28 drives the coil 19 to make a circular motion. During the rotation of the coil 19, the position of the coil 19 and the extrusion rod 28 remains stable, thereby effectively reducing the workload of clamping the coil 19 multiple times.
