Description

Technical Field

[0001] This invention relates to the field of metal welding technology, and more specifically to a rotary metal welding fixture. Background Technology

[0002] With the rapid development of society, the welding field has also developed rapidly. Welding technology plays an important role in various fields, mainly connecting two or more metal workpieces for application. Among them, the welding of metal pipes is widely used in the petroleum, chemical, and natural gas transportation industries to connect various fluid transportation pipelines, equipment, and containers. It not only has good sealing performance but also ensures the safe and efficient transportation of fluids. Therefore, the welding of metal pipes is an important component of the welding field.

[0003] In existing technologies, when welding metal pipes, two metal pipes need to be joined together first, and then the welding device is used to weld the joint. However, in actual operation, this welding method requires a clamping mechanism to hold the pipes before welding. In some cases, a robotic arm is used to align the two metal pipes before clamping and welding. Regardless of the welding method, it is not only costly, but the entire welding process involves multiple steps such as alignment, clamping, welding, and placement, resulting in wasted time and low overall welding efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a rotary metal welding fixture to overcome the above-mentioned shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A rotary metal welding fixture includes a conveyor belt for conveying workpieces, a support frame on the conveyor belt, a rotating plate rotatably mounted on the support frame, and a bearing mechanism on both sides of the rotating plate for supporting the metal pipe to be welded. The bearing mechanism is also provided with two clamping components.

[0007] The rotating plate is equipped with a welding mechanism, which is located between the two clamping components.

[0008] The supporting mechanism includes an arc-shaped plate disposed on a rotating plate, the arc-shaped plate forming a supporting space for supporting the metal tube;

[0009] The supporting mechanism is also equipped with a linkage component. When the metal tube is located in the supporting space, the linkage mechanism passively unlocks the clamping component to clamp the metal tube, and after welding is completed, the welded part automatically falls off.

[0010] As a further preferred embodiment of the present invention, a drive assembly is also provided on the rotating plate. During the rotation stroke, the bearing mechanism passively drives the metal tube to rotate through the drive assembly, so that the welding mechanism can weld the connection position of the two metal tubes.

[0011] In a further preferred embodiment of the present invention, the clamping assembly includes a sliding block slidably disposed on an arc-shaped plate, and a clamping block is rotatably disposed on the sliding block, the clamping block being adapted to the inner diameter of the metal tube.

[0012] In a further preferred embodiment of the present invention, a rotating rod is rotatably arranged between the arc-shaped plates, and a guide block is provided on the sliding block, the guide block being sleeved on the rotating rod.

[0013] In a further preferred embodiment of the present invention, a second elastic element is sleeved on the outside of the rotating rod. One end of the second elastic element is connected to the guide block, and the other end is connected to the arc plate. Under the elastic force of the second elastic element, the guide block tends to move toward the welding mechanism.

[0014] In a further preferred embodiment of the present invention, the linkage component includes an elastic column slidably disposed on an arc-shaped plate, and the arc-shaped plate is also slidably disposed on a transmission rod, and the transmission rod is provided with an inclined block adapted to the elastic column. One end of the arc-shaped plate is in contact with the inclined block, and the transmission rod is triggered to move through the arc-shaped plate during the downward pressing process.

[0015] In a further preferred embodiment of the present invention, the linkage component further includes a locking buckle slidably disposed on the arc plate. One end of the locking buckle is rounded and protrudes into the arc plate and is inserted into a locking groove opened on the guide block to lock the guide block and the sliding block. One end of the transmission rod is fixedly provided with a guide post, and the guide post is located in a limiting groove opened on the locking buckle. When the transmission rod slides, the locking buckle is driven to retract into the arc plate through the guide post.

[0016] In a further preferred embodiment of the present invention, the driving component includes a rotating ring rotatably mounted on a rotating plate, and a transmission column is fixedly mounted at one end of the clamping block. The transmission column can slide axially along the rotating ring, and the rotating ring can drive the transmission column to rotate circumferentially through a limit key.

[0017] In a further preferred embodiment of the present invention, a first pull rope is wound around the rotating ring, and a movable block is slidably disposed on the side wall of the rotating plate. One end of the first pull rope is fixedly connected to the rotating ring, and the other end is fixedly connected to the guide block.

[0018] It also includes a baffle assembly mounted on the support frame, which, during the rotation of the rotating plate, baffles the movable block and drives the rotating ring to rotate via the first pull rope.

[0019] In a further preferred embodiment of the present invention, the partition assembly includes an unlocking block and a partition block slidably disposed on the support frame, and also includes a drive ring rotatably disposed on the support frame, wherein the drive ring is movably connected to the unlocking block and the partition block respectively through a stop post.

[0020] In the above technical solution, the rotary metal welding fixture provided by the present invention has the following beneficial effects:

[0021] This invention, through its supporting mechanism and corresponding clamping components, can passively clamp two metal tubes to be welded. During the passive clamping process, the ends of the two metal tubes come into contact, which not only achieves automatic and tight connection at the contact point of the two metal tubes, but also passively triggers, ensuring stability, efficiency, and facilitating welding. Furthermore, the clamping components are passively driven to clamp the metal tubes as they are placed, and can automatically detach the metal tubes after welding, greatly improving clamping efficiency and overall welding efficiency of the metal tubes.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0040] Please refer to 1-12. A rotary metal welding fixture includes a conveyor belt 1 for conveying workpieces, a support frame 2 on the conveyor belt 1, a rotating plate 3 rotatably mounted on the support frame 2, and a bearing mechanism on both sides of the rotating plate 3 for bearing the metal pipe to be welded. The bearing mechanism is also provided with two clamping components.

[0041] The rotating plate 3 is equipped with a welding mechanism located between the two clamping components. The bearing mechanism includes an arc-shaped plate 302 on the rotating plate 3, which forms a bearing space for supporting the metal tubes. Specifically, the welding head 33 of the welding mechanism is located at the bottom center of the bearing space, and the bottom of the arc-shaped plate 302 is open, allowing the welding head 33 to contact the connection point of the two metal tubes within the bearing space.

[0042] The supporting mechanism is also equipped with a linkage component. When the metal tube is located in the supporting space, the linkage mechanism passively unlocks the clamping component to clamp the metal tube, and after welding is completed, the welded part automatically falls off.

[0043] Specifically, the bearing space formed within the bearing mechanism is adapted to the size of the metal tube to be supported. The clamping components are set on both sides of the bearing mechanism. During the passive clamping process, the two metal tubes are clamped by the clamping components, and the ends of the two metal tubes come into contact. This not only achieves a tight connection at the contact point of the two metal tubes, but also provides passive triggering, stability, efficiency, and ease of welding. Furthermore, the clamping components passively drive the clamping by the placement of the metal tubes, greatly improving the clamping efficiency and overall improving the welding efficiency of the metal tubes.

[0044] Furthermore, it also includes a drive assembly mounted on the rotating plate 3. During its rotational stroke, the carrying mechanism passively drives the metal tube to rotate, enabling the welding mechanism to weld the connection point of the two metal tubes. Specifically, by using the drive assembly in conjunction with the carrying mechanism and the rotating plate 3, this invention enables the welding mechanism to perform rotational welding on the metal tube connection point during the rotational transport process of the rotating plate 3, greatly improving welding efficiency.

[0045] Furthermore, the clamping assembly includes a sliding block 4 slidably disposed on the arc plate 302, and a clamping block 41 is rotatably disposed on the sliding block 4, the clamping block 41 being adapted to the inner diameter of the metal tube.

[0046] In a further embodiment of the present invention, a rotating rod 31 is rotatably arranged between the arc-shaped plates 302, and a guide block 42 is provided on the sliding block 4, the guide block 42 being sleeved on the rotating rod 31. Through the arrangement of the arc-shaped plates 302, the guide block 42, and the rotating rod 31, stable sliding of the clamping block 41 can be achieved.

[0047] In a further embodiment of the present invention, a second elastic element 311 is sleeved on the outside of the rotating rod 31. One end of the second elastic element 311 is connected to the guide block 42, and the other end is connected to the arc plate 302. Under the elastic force of the second elastic element 311, the guide block 42 has a tendency to move toward the welding mechanism.

[0048] In another embodiment of the present invention, the linkage component includes an elastic column 7 slidably disposed on an arc-shaped plate 302, and a transmission rod 72 slidably disposed on the arc-shaped plate 302. An inclined block 71 adapted to the elastic column 7 is disposed on the transmission rod 72, and one end of the arc-shaped plate 302 contacts the inclined block 71. During the downward pressing of the arc-shaped plate 302, the transmission rod 72 is triggered to move. Specifically, the elastic column 7 provided in this application has two prominent effects: first, as a component for unlocking the linkage component, it can passively unlock when the metal tube is placed; second, it can support the metal tube, preventing it from adhering to the arc-shaped plate 302 and keeping the metal tube suspended. That is, it allows the position of the metal tube to be adapted to the clamping block 41, greatly improving the functionality of the elastic column 7.

[0049] In a further embodiment of the present invention, the linkage component further includes a locking buckle 73 slidably disposed on the arc-shaped plate 302. One end of the locking buckle 73 is rounded and protrudes into the arc-shaped plate 302, inserting into a locking groove opened on the guide block 42 to lock the guide block 42 and the sliding block 4. One end of the transmission rod 72 is fixedly provided with a guide post 721, and the guide post 721 is located in a limiting groove 7301 opened on the locking buckle 73. When the transmission rod 72 slides, the locking buckle 73 is driven to retract into the arc-shaped plate 302 through the guide post 721. Specifically, to ensure that the locking buckle 73 pops out again after retraction, a first elastic member 731 is provided on one side of the locking buckle 73, and the other side of the first elastic member 731 abuts against the groove of the arc-shaped plate 302. The elastic force can drive the locking buckle 73 to pop out.

[0050] In a further embodiment of the present invention, the driving component includes a rotating ring 32 rotatably mounted on a rotating plate 3, and a transmission column 411 fixedly mounted at one end of a clamping block 41. The transmission column 411 can slide axially along the rotating ring 32, and the rotating ring 32 can drive the transmission column 411 to rotate circumferentially via a limit key. Specifically, when the rotating ring 32 rotates, it drives the transmission column 411 to rotate synchronously, thereby driving the clamped metal tube to rotate synchronously. This enables the welding mechanism to perform circumferential welding at the connection point of the two metal tubes, improving its welding efficiency. A torsion spring is also provided on the rotating ring 32, and its elasticity allows the rotating ring 32 to have the ability to return to its original rotation after being pulled and rotated by the first pull rope 5. The setting of the torsion spring is a technical means known to those skilled in the art, and therefore is not described in detail here.

[0051] In a further embodiment of the present invention, a first pull rope 5 is wound around the rotating ring 32, and a movable block 53 is slidably disposed on the side wall of the rotating plate 3. One end of the first pull rope 5 is fixedly connected to the rotating ring 32, and the other end is fixedly connected to the guide block 42.

[0052] It also includes a baffle assembly installed on the support frame 2, which baffles the movable block 53 during the rotation of the rotating plate 3, and drives the rotating ring 32 to rotate through the first pull rope 5.

[0053] In a further embodiment of the present invention, the partition assembly includes an unlocking block and a partition block 62 slidably disposed on the support frame 2, and also includes a drive ring 6 rotatably disposed on the support frame 2. The drive ring 6 is movably connected to the unlocking block and the partition block 62 respectively through a stop post 63.

[0054] Specifically, the surface of the unlocking block is chamfered so that the sliding roller can press against the unlocking block when it passes by. The position of the unlocking block is... Figure 7The right-hand positioning allows the partition block 62 to be unlocked when the sliding roller is not vertical. A torsion spring is installed on the shaft where the drive ring 6 rotates with the rotating plate 3; its elasticity causes the partition block 62 to protrude onto the rotating plate 3. This ensures that, in its natural state, the partition block 62 is located outside the rotating plate 3. Furthermore, the partition block 62 has a clearance groove, and a limiting roller 52 is rotatably mounted on the rotating plate 3. The first pull rope 5 connects to the movable block 53 after contacting the limiting roller 52. It can guide the first pull rope 5. During the rotation of the rotating plate 3, the limiting roller 52 gradually contacts the unlocking block, and then squeezes the unlocking block support frame 2 to slide inside. Then, the drive ring 6 rotates to drive the partition block 62 to move towards the outside of the support frame 2, so that the movable block 53 gradually moves to the position of the clearance groove, that is, the partition can be released. Then the movable block 53 slides along the arc-shaped slide groove 301, so that the movable block 53 is in the initial position, and the first pull rope 5 is wrapped around the rotating ring 32.

[0055] Furthermore, to facilitate the return of the clamping components after clamping, a second pull rope 51 is provided on the movable block 53. The other end of the second pull rope 51 is also connected to the movable block 53. That is, during the rotation of the rotating plate 3, it can drive the two clamping components of the device to release the clamping, and drive the two clamping blocks 41 to gradually detach from the metal tube and contact the clamping. Specifically, the first pull rope 5 and the second pull rope 51 are respectively provided with guide rollers at the reversal position of the route to facilitate the smooth sliding of the pull rope. That is, through the cooperation of the movable block 53 and the first pull rope 5 and the second pull rope 51, this application can not only realize the rotation of the rotating ring 32 to achieve passive rotation of the metal tube, but also pull the two clamping blocks 41.

[0056] Specifically, to facilitate the synchronous sliding of the two opposing clamping blocks 41, this application provides a spiral groove 3101 on the rotating rod 31 and a fixing post 421 on the guide block 42. The fixing post 421 is located within the spiral groove 3101. After the clamping blocks 41 are unlocked, during the movement under the elastic force of the second elastic member 311, the movement of the fixing post 421 within the spiral groove 3101 drives the rotating rod 31 to rotate. The spiral direction of the spiral groove 3101 where the two clamping blocks 41 are located... Conversely, during the rotation of the rotating rod 31, the fixed column 421 ensures that the two clamping blocks 41 slide synchronously. The above structure also has another outstanding effect: the fixed column 421 and the spiral groove 3101 can reduce the movement speed of the clamping blocks 41, which greatly reduces the impact on the metal tube caused by the excessive clamping caused by the elastic force of the second elastic element 311. The overall coordination is orderly and the mobility is high. It not only saves a lot of driving costs, but also enables the device to operate stably.

[0057] In the process of using this invention, firstly, two metal tubes are placed in the bearing space formed by the arc-shaped plate 302. Then, the metal tubes contact the elastic column 7. Due to the weight of the metal tubes, the elastic column 7 is compressed and moves downward. During the downward movement, the lower end of the elastic column 7 abuts against the inclined block 71. Then, the inclined block 71 drives the transmission rod 72 and the connected guide post 721 to move towards the locking buckle 73. Then, through the limiting of the guide post 721 and the limiting groove 7301, the locking buckle 73 retracts into the arc-shaped plate 302, that is, the locking buckle 73 disengages from the sliding. The locking groove on block 4 then unlocks the clamping block 41 and moves towards the middle position of the bearing space under the elastic force of the second elastic element 311. Then the movement of the fixed column 421 in the spiral groove 3101 drives the rotating rod 31 to rotate. The two clamping blocks 41 can be ensured to slide synchronously through the action of the fixed column 421. Finally, the clamping block 41 moves and inserts into the two metal tubes, squeezing the two metal tubes together. At this time, the rotation continues to rotate. Then the welding mechanism starts to operate and welds the connection position of the two metal tubes.

[0058] During the movement of the rotating plate 3, the movable block 53 is blocked by the partition block 62. As the rotating plate 3 continues to rotate, the movable block 53 does not move. Then, limited by the limiting roller 52, the movable block 53 pulls the first pull rope 5 and the second pull rope 51. The length of the second pull rope 51, excluding the length wound around the rotating ring 32, is greater than the length of the first pull rope 5. The first pull rope 5 then pulls the rotating ring 32 to rotate, thereby causing the connected sliding block 4 and clamping block 41 to rotate, thus enabling the two metal... The rotation of the tube allows the welding mechanism to perform full welding on the metal tube. After one end of the rotating plate 3 is displaced, the clamping block 41 rotates one revolution. Then, the rotating plate 3 continues to rotate, that is, it continuously pulls the first pull rope 5 and the second pull rope 51. At this time, the second pull rope 51 is tightened and continues to pull the connected guide block 42. Then, it drives the connected sliding block 4 and the clamping block 41 to move closer to the support frame 2, that is, it no longer clamps the metal tube. When the rotating plate 3 rotates to tilt downwards, the metal tube automatically falls onto the conveyor belt 1. Meanwhile, the rotating plate 3 continues to rotate, continuously pulling the first pull rope 5 and the second pull rope 51. Then, the second pull rope 51 continuously drives the connected guide block 42 to slide, eventually causing the guide block 42 to move to its initial position, that is, the locking groove on the guide block 42 corresponds to the locking block. The locking block is no longer under the pressure of the metal tube and, under the elastic force of the first elastic element 731, it is inserted back into the locking groove. At the same time, the limiting roller 52 squeezes the unlocking block and then moves inward, driving the drive ring 6 to rotate along its axis, that is, driving the connected partition block 62 toward the active position. The moving block 53 moves in the direction of the moving block 53, and the moving block 53 gradually moves to the position of the clearance groove, no longer blocking the moving block 53. Then, under the action of the torque spring of the rotating ring 32, the rotating ring 32 rotates, driving the second pull rope 51 to wrap around the rotating ring 32, and then the moving block 53 returns to the initial position. Then, as the rotating plate 3 continues to rotate, when the bearing space is horizontal and upward, two metal tubes are put in again, and then the clamping, rotation and other steps are performed again according to the above steps, so that the welding operation of the metal tubes to be welded can be performed continuously without stopping the machine.

[0059] This application, through the above-mentioned structural configuration, enables the rotating plate 3 to passively clamp and rotate during the rotation process, allowing the two welded metal tubes to automatically detach and then passively return each structure to its initial position. This enables automated and continuous welding of the two metal tubes, not only improving the tightness of the contact between the two metal tubes during welding but also achieving automated rotational welding of the metal tubes, greatly improving welding quality and efficiency.

[0060] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
