Description

Technical Field

[0001] This invention relates to a welding apparatus, and more particularly to a welding apparatus integrated into a welding fixture. Background Technology

[0002] With the development of science and technology, welding technology has also been improved. During the welding process, fixtures can play a fixing role, which improves the welding quality. In the process of processing workpieces, it is usually necessary to weld two cylindrical workpieces together. When welding, it is necessary to first use a fixture to limit the cylindrical workpieces, and then the worker adjusts the position of the welding gun so that the welding head of the welding gun is aligned with the ends of the two cylindrical workpieces. However, in reality, the lengths of the two cylindrical workpieces are not the same. Before welding, the worker needs to adjust the position of the welding gun. There is a situation where the position of the welding gun is not adjusted accurately, which leads to inaccurate welding and poor welding quality. Summary of the Invention

[0003] To address the shortcomings of current welding methods where inaccurate welding torch position adjustment leads to inaccurate welding, this invention provides a welding device integrated into a welding fixture that aligns the welding torch with the end of the cylindrical workpiece, resulting in more accurate welding.

[0004] The technical solution is as follows: A welding device integrated into a welding fixture includes an N-shaped mounting plate, an L-shaped mounting plate, a mounting frame, a welding torch, a clamping device, and a locking device. Two L-shaped mounting plates are fixedly connected to the inner side of the N-shaped mounting plate, and the two L-shaped mounting plates are symmetrically arranged. The mounting frame is mounted on the clamping device, and the mounting frame has a sliding groove. The welding torch is slidably connected to the sliding groove of the mounting frame. The clamping device is located between the two L-shaped mounting plates, and the locking device is located on the mounting frame.

[0005] Optionally, the clamping device includes a mounting plate, a motor, a three-jaw chuck, sliding blocks, a guide plate, and a clamping rod. The mounting plate is rotatably connected between two L-shaped mounting plates. The mounting bracket is fixed to the mounting plate. The motor is fixed to the side of the mounting plate near the N-shaped mounting plate. The output shaft of the motor is rotatably connected to the mounting plate. The three-jaw chuck is fixed to the output shaft of the motor. Three sliding blocks are slidably connected to the side of the three-jaw chuck away from the mounting plate. The guide plate is fixed to the side of the three-jaw chuck away from the mounting plate. The clamping rod is fixed to the side of the sliding blocks away from the three-jaw chuck. The clamping rod is slidably connected to the guide plate.

[0006] Optionally, the locking device includes a locking rod, the mounting bracket has a mounting hole inside, one of the L-shaped mounting plates has a locking hole, the locking rod is slidably connected to the mounting hole, and the end of the locking rod near the N-shaped mounting plate is engaged in the locking hole.

[0007] Optionally, it also includes a positioning device mounted on a mounting frame. The positioning device includes a slider, a bearing, a mounting ring, a threaded rod, a connecting rod, a clamping plate, and a limiting rod. The slider is slidably connected to a groove on the mounting frame and is also fixedly connected to a welding torch. The outer ring of the bearing is fixedly connected to the side of the slider away from the mounting frame. The mounting ring is fixedly connected to the inner ring of the bearing. The mounting ring has a threaded hole, and a threaded rod is threadedly connected to the threaded hole. The connecting rod is rotatably connected to the mounting ring. The clamping plate is slidably connected to the end of the connecting rod away from the threaded rod. The limiting rod is fixedly connected to the threaded rod and is slidably connected to the connecting rod.

[0008] Optionally, it also includes a material clamping device, which is disposed on the guide plate. The material clamping device includes a sleeve rod, a return spring, a pull rod, and a clamping head. The sleeve rod is fixedly connected to the side of the guide plate away from the three-jaw chuck. One end of the return spring is fixedly connected to the side of the guide plate away from the three-jaw chuck. The other end of the return spring is rotatably connected to the pull rod. The end of the pull rod away from the guide plate passes through a bearing. The return spring is located inside the sleeve rod. The clamping head is fixedly connected to the pull rod and is located outside the sleeve rod.

[0009] Optionally, it also includes a handle fixed to the side of the mounting bracket away from the N-shaped mounting plate.

[0010] Optionally, it also includes a rubber pad, which is fixed to the side of the guide plate away from the three-jaw chuck, the sleeve rod passes through the rubber pad, and the clamping rod is slidably connected to the rubber pad.

[0011] Optionally, it also includes rubber rings, with three rubber rings provided at one end of the locking rod near the N-shaped mounting plate, the rubber rings being located inside the lock hole.

[0012] Optionally, it also includes guide wheels, with a plurality of guide wheels rotatably connected to the clamping rod.

[0013] The beneficial effects of this invention are:

[0014] 1. The cylindrical workpiece is opened from the inside by three clamping rods, which clamps the cylindrical workpiece and facilitates subsequent welding. The rotation of the clamping rods causes the two cylindrical workpieces to rotate, allowing the welding torch to quickly weld along the ends of the two cylindrical workpieces.

[0015] 2. The downward swing of the mounting frame causes the locking rod, mounting plate, three-jaw chuck, sliding block, guide plate, clamping rod and cylindrical workpiece to swing downward together. The welded cylindrical workpiece slides down along the clamping rod under the action of gravity, making it easy to remove the welded cylindrical workpiece.

[0016] Third, the clamping plate positions one of the cylindrical workpieces, aligning the end of the cylindrical workpiece with the welding torch. When the ends of the two cylindrical workpieces are aligned, the welding torch is simultaneously aligned with the ends of both cylindrical workpieces, thus enabling more accurate welding and resulting in better welding quality.

[0017] Fourth, by contacting the end of one of the cylindrical workpieces with the chuck, the chuck limits the cylindrical workpiece, preventing it from shifting during welding and facilitating better welding of the cylindrical workpiece. Attached Figure Description

Detailed Implementation

[0030] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0031] Example 1

[0032] A welding device integrated into a welding fixture, such as Figures 1-3 As shown, the device includes an N-shaped mounting plate 1, an L-shaped mounting plate 2, a mounting frame 3, a welding torch 31, a clamping device 4, and a locking device 5. Two L-shaped mounting plates 2 are bolted to the inner side of the N-shaped mounting plate 1, and the two L-shaped mounting plates 2 are symmetrically arranged. The mounting frame 3 is mounted on the clamping device 4 and has a sliding groove. The welding torch 31 is slidably connected to the sliding groove of the mounting frame 3 and is used for welding cylindrical workpieces. The clamping device 4 is positioned between the two L-shaped mounting plates 2 and is used to clamp the cylindrical workpiece for subsequent welding. The locking device 5 is mounted on the mounting frame 3 and is used to lock the mounting frame 3 and the clamping device 4 for stable welding.

[0033] The clamping device 4 includes a mounting plate 41, a motor 42, a three-jaw chuck 43, a sliding block 431, a guide plate 44, and a clamping rod 45. The mounting plate 41 is rotatably connected between two L-shaped mounting plates 2. The mounting frame 3 is fixedly connected to the mounting plate 41 and is horizontally positioned. The motor 42 is riveted to the side of the mounting plate 41 near the N-shaped mounting plate 1. The output shaft of the motor 42 is rotatably connected to the mounting plate 41. The three-jaw chuck 43 is fixedly mounted on the output shaft of the motor 42. Three sliding blocks 431 are slidably connected to the side of the three-jaw chuck 43 away from the mounting plate 41. The guide plate 44 is fixedly connected to the side of the three-jaw chuck 43 away from the mounting plate 41. The clamping rod 45 is fixedly connected to the side of the sliding block 431 away from the three-jaw chuck 43 and is horizontally positioned. The clamping rod 45 is used to clamp the inner wall of the cylindrical workpiece and is slidably connected to the guide plate 44.

[0034] The locking device 5 includes a locking rod 53. The mounting bracket 3 has a mounting hole 51 inside. One of the L-shaped mounting plates 2 has a locking hole 52. The locking rod 53 is slidably connected to the mounting hole 51. The locking rod 53 is horizontally set. The end of the locking rod 53 near the N-shaped mounting plate 1 is inserted into the locking hole 52.

[0035] In practical use, the worker places the two cylindrical workpieces to be welded onto the outer side of the three clamping rods 45 in sequence. Then, the worker adjusts the three-jaw chuck 43, causing the three sliding blocks 431 to move away from each other. This movement of the sliding blocks 431 moves the clamping rods 45, causing them to open from the inside of the cylindrical workpieces, thus clamping them for subsequent welding. The worker then pulls the welding torch 31 along the mounting frame 3, aligning the welding head of the torch 31 with the ends of the two cylindrical workpieces. Next, the worker starts the motor 42 and the welding torch 31. The motor 42 drives the three-jaw chuck 43 to rotate via its output shaft. This rotation of the three-jaw chuck 43 causes the sliding blocks 431 and clamping rods 45 to rotate, which in turn rotates the two cylindrical workpieces, allowing the welding torch 31 to quickly weld along the ends of the two cylindrical workpieces. After welding, the worker turns off the motor 42 and the welding torch 31, and then adjusts the three-jaw chuck 43 again, moving the three sliding blocks 431 closer together. Resetting the sliding block 431 will cause the clamping rod 45 to reset, so that the three clamping rods 45 no longer clamp the cylindrical workpiece. The worker pulls the locking rod 53 to move along the mounting hole 51 away from the N-shaped mounting plate 1, and the locking rod 53 disengages from the locking hole 52. Then the worker rotates the mounting frame 3 to swing it downward. The downward swing of the mounting frame 3 causes the locking rod 53, the mounting plate 41, the three-jaw chuck 43, the sliding block 431, the guide plate 44, the clamping rod 45 and the cylindrical workpiece to swing downward together. Under the influence of gravity, the workpiece slides down along the clamping rod 45, making it easier to remove the welded cylindrical workpiece. Then, the worker rotates the mounting frame 3 to swing upwards and reset it. The swinging reset of the mounting frame 3 drives the locking rod 53, mounting plate 41, three-jaw chuck 43, sliding block 431, guide plate 44 and clamping rod 45 to swing and reset. Then, the worker pushes the locking rod 53 to reset it towards the N-shaped mounting plate 1, so that the locking rod 53 re-engages into the locking hole 52, thereby locking the mounting frame 3 and facilitating the next welding.

[0036] Example 2

[0037] Based on Example 1, such as Figures 4-6As shown, it also includes a positioning device 6, which is mounted on the mounting frame 3. The positioning device 6 is used to align the welding torch 31 with the ends of the two cylindrical workpieces, enabling more accurate welding. The positioning device 6 includes a slider 61, a bearing 62, a mounting ring 63, a threaded rod 65, a connecting rod 66, a clamping plate 67, and a limiting rod 68. The slider 61 is slidably connected to the slide groove of the mounting frame 3, and the slider 61 is also fixedly connected to the welding torch 31. The outer ring of the bearing 62 is fixedly connected to the side of the slider 61 away from the mounting frame 3. The mounting ring 63 is fixedly connected to... On the inner ring of bearing 62, the mounting ring 63 has a threaded hole 64, and a threaded rod 65 is threadedly connected to the threaded hole 64. The threaded rod 65 is vertically arranged and is used to limit the cylindrical workpiece. The connecting rod 66 is rotatably connected to the mounting ring 63 and is horizontally arranged. The clamping plate 67 is slidably connected to the end of the connecting rod 66 away from the threaded rod 65 and is used to limit the cylindrical workpiece. The limiting rod 68 is fixed to the threaded rod 65 and is slidably connected to the connecting rod 66.

[0038] Initially, the worker pulls the clamping plate 67 upwards, then pushes one of the cylindrical workpieces into the inner side of the bearing 62. Simultaneously, one of the cylindrical workpieces passes through the inner side of the mounting ring 63. The worker continues to push one of the cylindrical workpieces, positioning it on the outside between the three clamping rods 45. Once one of the cylindrical workpieces is in the correct position, the worker pushes the clamping plate 67 downwards to reset it. Then, another cylindrical workpiece is pushed into the bearing 62 and the inner side of the mounting ring 63, with its end contacting the clamping plate 67. The clamping plate 67 positions the other cylindrical workpiece, aligning its end with the welding torch 31. Next, the worker rotates the threaded rod 65, which moves downwards along the threaded hole 64. The threaded rod 65 moves downward and comes into close contact with the outer wall of another cylindrical workpiece. The downward movement of the threaded rod 65 causes the limiting rod 68 to move downward. The downward movement of the limiting rod 68 causes the connecting rod 66 and the clamping plate 67 to swing upward. Then, the worker pulls the clamping plate 67 upward again, moving the clamping plate 67 away from the end of the cylindrical workpiece, which facilitates subsequent welding of the cylindrical workpiece. Then, the worker continues to push the other cylindrical workpiece to move. The continued movement of the other cylindrical workpiece causes the threaded rod 65, the mounting ring 63, the bearing 62, the slider 61, and the welding torch 31 to move together. When the ends of the two cylindrical workpieces are aligned, the welding torch 31 is simultaneously aligned with the ends of the two cylindrical workpieces, which enables more accurate welding and results in better welding quality.

[0039] Example 3

[0040] Based on Example 1, such as Figures 7-8As shown, it also includes a material clamping device 7, which is mounted on the guide plate 44. The material clamping device 7 is used to clamp the cylindrical workpiece, further limiting the position of the cylindrical workpiece, so as to facilitate better welding of the cylindrical workpiece. The material clamping device 7 includes a sleeve rod 71, a return spring 72, a pull rod 73, and a clamp head 74. The sleeve rod 71 is welded to the side of the guide plate 44 away from the three-jaw chuck 43 and is horizontally arranged. One end of the return spring 72 is fixed to the side of the guide plate 44 away from the three-jaw chuck 43, and the other end of the return spring 72 is rotatably connected to the pull rod 73. The pull rod 73 is horizontally arranged, and the end of the pull rod 73 away from the guide plate 44 passes through the bearing 62. The return spring 72 is located inside the sleeve rod 71. The clamp head 74 is fixed to the pull rod 73 and is located outside the sleeve rod 71. The clamp head 74 is used to limit the position of the cylindrical workpiece.

[0041] When the worker pushes in the cylindrical workpiece, the cylindrical workpiece is simultaneously fitted over the pull rod 73 and the sleeve rod 71. After the cylindrical workpiece is placed, the worker pulls the pull rod 73, and the movement of the pull rod 73 causes the chuck 74 to move. Then, the worker rotates the pull rod 73, which in turn causes the chuck 74 to rotate, so that the chuck 74 contacts the end of one of the cylindrical workpieces. This allows the chuck 74 to limit the cylindrical workpiece, preventing it from shifting during welding and facilitating better welding. After welding is completed, the worker rotates the pull rod 73 and the chuck 74 to reset, and the chuck 74 no longer limits the cylindrical workpiece, making it easier to remove.

[0042] Example 4

[0043] Based on Example 1, such as Figure 9 As shown, it also includes a handle 8, which is fixed to the side of the mounting frame 3 away from the N-shaped mounting plate 1. The handle 8 facilitates the worker to rotate the mounting frame 3.

[0044] When the worker rotates the mounting bracket 3 to swing it downwards or upwards, the worker holds the handle 8 for easy operation.

[0045] Example 5

[0046] Based on Example 1, such as Figure 9 As shown, it also includes a rubber pad 9, which is fixed to the guide plate 44 on the side away from the three-jaw chuck 43. The sleeve rod 71 passes through the rubber pad 9, and the clamping rod 45 is slidably connected to the rubber pad 9. The rubber pad 9 is used to assist the chuck 74 in limiting the cylindrical workpiece.

[0047] During welding, the end of the cylindrical workpiece contacts the rubber pad 9. The rubber pad 9 and the clamp 74 together limit the cylindrical workpiece, making it easier to weld the cylindrical workpiece.

[0048] Example 6

[0049] Based on Example 1, such as Figure 3 and Figure 10 As shown, it also includes rubber rings 10. Three rubber rings 10 are provided at one end of the locking rod 53 near the N-shaped mounting plate 1. The rubber rings 10 are located inside the lock hole 52 and are used to restrict the locking rod 53 within the lock hole 52.

[0050] When the worker pushes the locking rod 53 into the lock hole 52, the movement of the locking rod 53 causes the rubber ring 10 to move, so that the rubber ring 10 is engaged in the lock hole 52, which can better lock the locking rod 53 and facilitate stable welding.

[0051] Example 7

[0052] Based on Example 1, such as Figure 11 As shown, it also includes guide wheels 11. Several guide wheels 11 are rotatably connected to the clamping rod 45. The guide wheels 11 are used to guide the cylindrical workpiece.

[0053] The inner wall of the cylindrical workpiece contacts the guide wheel 11. The movement of the cylindrical workpiece will drive the guide wheel 11 to rotate, so that the guide wheel 11 guides the cylindrical workpiece, so that the cylindrical workpiece can only move left and right, which makes it easy to adjust the position of the cylindrical workpiece before welding.
