[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0040] Welding is a manufacturing process and technology that joins metals or other thermoplastic materials by heating, high temperature, or high pressure. The energy sources for welding are diverse, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound, and it has wide applications in industrial production, including automobile manufacturing, aerospace, shipbuilding, and petrochemicals.

[0041] Currently, when using welding equipment to perform welding operations on workpieces, because the position of the welding equipment is fixed, the position of the workpiece to be welded needs to be adjusted frequently to achieve welding in different positions.

[0042] However, when adjusting the position of the workpiece to be welded, it is necessary to disassemble and assemble the fixture, which wastes a lot of time, resulting in a long welding cycle and low welding efficiency.

[0043] Therefore, in order to shorten the welding operation cycle and improve the welding operation efficiency, this embodiment provides a welding alignment device.

[0044] like Figures 1 to 3 As shown, the welding alignment device includes a first adjustment unit 1, a second adjustment unit 2, a third adjustment unit 3, a fourth adjustment unit 4, and a welding unit 5. The first adjustment unit 1 includes a first linear module 11 and a first support plate 12. The first linear module 11 drives the first support plate 12 to slide along a first direction. The second adjustment unit 2 includes a second linear module 21 and a second support plate 22. The second linear module 21 is connected to the first support plate 12 and drives the second support plate 22 to slide along a second direction. The third adjustment unit 3 includes a third linear module 31 and a third support plate 32. The third linear module 31... The third linear module 31 is connected to the second support plate 22 and is used to drive the third support plate 32 to slide along the third direction. The step distance of the third linear module 31 driving the third support plate 32 along the third direction is L1. The fourth adjustment unit 4 includes a fourth linear module 41 and a fourth support plate 42. The fourth linear module 41 is connected to the third support plate 32 and is used to drive the fourth support plate 42 to slide along the third direction. The step distance of the fourth linear module 41 driving the fourth support plate 42 along the third direction is L2, and L2 < L1. The welding unit 5 includes a welding torch 51, which is connected to the fourth support plate 42.

[0045] This welding alignment device, through the first adjustment unit 1, the second adjustment unit 2, and the third adjustment unit 3, enables the welding torch 51 on the welding unit 5 to move freely along the first, second, and third directions. This allows welding operations to be performed at different welding positions by moving the welding torch 51, eliminating the need to disassemble and assemble the fixtures that fix the workpiece to be welded, thus shortening the welding cycle and improving welding efficiency. Furthermore, by setting a fourth adjustment unit 4, the step distance L2 of the fourth linear module 41 driving the fourth support plate 42 along the third direction is made smaller than the step distance L1 of the third linear module 31 driving the third support plate 32 along the third direction. This allows the third adjustment unit 3 to perform coarse adjustment of the welding torch 51 along the third direction, and the fourth adjustment unit 4 to perform fine adjustment of the welding torch 51 along the third direction, thereby improving the adjustment accuracy.

[0046] Optionally, the welding alignment device further includes a displacement detection unit 6, which includes a displacement mounting plate 61, a displacement connecting plate 62, a measuring rod 63, and a detection body 64. The displacement connecting plate 62 is connected to the fourth bearing plate 42. One end of the measuring rod 63 is slidably inserted into the detection body 64, and the other end of the measuring rod 63 is connected to the displacement connecting plate 62. The detection body 64 is connected to the displacement mounting plate 61 and is used to detect the length of the measuring rod 63 extending out of the detection body 64. The displacement mounting plate 61 is connected to the third bearing plate 32.

[0047] By connecting the detection body 64 of the displacement detection unit 6 to the third support plate 32 via the displacement mounting plate 61, and connecting the measuring rod 63, which is slidably inserted into the detection body 64, to the fourth support plate 42 via the displacement connecting plate 62, when the fourth support plate 42 moves along the third direction under the drive of the fourth linear module 41, the length of the measuring rod 63 extending out of the detection body 64 is detected by the detection body 64, thereby determining the moving distance of the fourth support plate 42 along the third direction, ensuring the accuracy of the position of the welding torch 51 moved by the fourth adjustment unit 4 as a fine-tuning unit.

[0048] Furthermore, the displacement detection unit 6 also includes a buffer spring 65, which is sleeved on the measuring rod 63 and located between the detection body 64 and the displacement connecting plate 62. By setting the buffer spring 65 sleeved on the measuring rod 63 between the detection body 64 and the displacement connecting plate 62, it is ensured that when the fourth bearing plate 42 drives the welding torch 51 to move closer to the detection body 64 in a third direction, the buffer spring 65 is compressed to buffer the movement, preventing the displacement connecting plate 62 from colliding with the detection body 64 due to excessive movement speed, thus avoiding damage to the detection body 64.

[0049] Optionally, the second linear module 21 and the fourth linear module 41 have the same structure as the first linear module 11. The first linear module 11 includes a transmission assembly 111, which includes a power component 1111, a lead screw housing 1112, a transmission lead screw 1113, a slide rail 1114, and a slider 1115. The slide rail 1114 is located inside the lead screw housing 1112, and the slider 1115 is slidably located on the slide rail 1114. The transmission lead screw 1113 is rotatably located inside the lead screw housing 1112 and passes through the slider 1115, and is threadedly connected to the slider 1115. The power component 1111 is used to drive the transmission lead screw 1113 to rotate.

[0050] By using the power component 1111 to drive the transmission screw 1113 to rotate, the slider 1115, connected to the transmission screw 1113 via a thread, can convert the rotational motion of the transmission screw 1113 into the linear motion of the slider 1115, resulting in high transmission efficiency. Furthermore, due to the high positional accuracy and repeatability of the screw drive, accurate position and motion control of the slider 1115 during sliding can be achieved. In addition, because the slider 1115 has a certain weight, a screw drive with strong load capacity is used, capable of withstanding large axial and radial loads, thus ensuring the structural reliability and safety of the slider 1115 during movement. Moreover, when the power component 1111 suddenly loses power, the screw drive's strong self-locking property ensures that the slider 1115 remains stable even in the event of a power outage or loss of driving force, preventing accidental movement. In this embodiment, since the second linear module 21 and the fourth linear module 41 have the same structure as the first linear module 11, the first support plate 12, the second support plate 22 and the fourth support plate 42 are all connected to their respective sliders 1115, wherein the power component 1111 is a motor.

[0051] Optionally, the transmission assembly 111 further includes a driving wheel 1116, a driven wheel 1117, and a transmission belt 1118. The driven wheel 1117 is connected to the end of the transmission screw 1113, and the transmission belt 1118 is sleeved on the outside of the driving wheel 1116 and the driven wheel 1117. The output end of the power component 1111 is connected to the driving wheel 1116 and is used to drive the driving wheel 1116 to rotate.

[0052] By employing belt drive, power transmission between the power component 1111 and the transmission screw 1113 is achieved, resulting in a smoother transmission process, reduced impact and vibration during transmission, lower noise and vibration levels, protection of mechanical equipment, and reduced wear on components. Furthermore, in the event of jamming during operation, the slippage between the drive pulley 1116 and the transmission belt 1118 can also protect the power component 1111. In this embodiment, to protect the drive pulley 1116, driven pulley 1117, and transmission belt 1118, a transmission housing 1119 is also provided, which encloses the drive pulley 1116, driven pulley 1117, and transmission belt 1118.

[0053] Optionally, the first linear module 11 further includes an auxiliary component 112, which includes an auxiliary roller 1121. A mounting groove is provided on the slider 1115, and the auxiliary roller 1121 is rotatably disposed within the mounting groove. By providing a mounting groove on the slider 1115 and placing the auxiliary roller 1121 within it, the auxiliary roller 1121 not only limits the slider 1115 within the screw housing 1112 but also creates rolling friction between the inner wall of the screw housing 1112 and the slider 1115, reducing the frictional resistance between them.

[0054] In this embodiment, the auxiliary component 112 further includes a wheel seat 1122 and a rotating shaft 1123. The wheel seat 1122 is installed in the mounting groove, and the rotating shaft 1123 is disposed between the two wheel seats 1122. The auxiliary rollers 1121 are rotatably disposed on the rotating shaft 1123. The number of auxiliary rollers 1121 can be freely set according to requirements. In this embodiment, two auxiliary rollers 1121 are disposed on the rotating shaft 1123.

[0055] Optionally, the auxiliary component 112 further includes a follower belt 1125, a pulley 1124, and a follower belt 1125. The follower belt 1125 is rotatably disposed within the screw housing 1112, and the follower belt 1125 is sleeved on the outside of the pulley 1124 and connected to the slider 1115. By providing the follower belt 1125 connected to the slider 1115, the follower belt 1125 can absorb some vibration and impact, reducing the direct force on the transmission screw 1113, thereby extending the service life of the transmission screw 1113 and reducing the occurrence of mechanical failures.

[0056] Optionally, the first adjustment unit 1 further includes a first fixing plate 13, and the second adjustment unit 2 further includes a second fixing plate 23. The first fixing plate 13 is connected to the first support plate 12, the second linear module 21 is connected to the first fixing plate 13, the second fixing plate 23 is vertically connected to the second support plate 22, and the third linear module 31 is connected to the second fixing plate 23. The welding alignment device further includes an origin unit 7 and a workbench unit 8. The workbench unit 8 includes a worktable 81, the first linear module 11 is connected to the worktable 81, the origin unit 7 includes a positioning plate 71 and a moving plate 72, the positioning plate 71 is provided with an origin marking line, and the moving plate 72 is provided with a positioning marking line. The worktable 81, the first fixing plate 13 and the second fixing plate 23 are all connected to the positioning plate 71, and the first support plate 12, the second support plate 22 and the third support plate 32 are all connected to the moving plate 72.

[0057] By connecting positioning plates 71 to the worktable 81, the first fixed plate 13, and the second fixed plate 23, and connecting moving plates 72 to the first bearing plate 12, the second bearing plate 22, and the third bearing plate 32, when the welding alignment device needs to be reset, it is only necessary to ensure that the origin mark on the positioning plate 71 coincides with the positioning mark on the moving plate 72 to ensure the accuracy of the reset position and avoid incomplete reset, which would affect the zero-point calibration during the next welding operation.

[0058] In this embodiment, the opposite sides of the positioning plate 71 and the moving plate 72 are both isosceles triangles, so as to determine the origin line on the positioning plate 71 and the positioning line on the moving plate 72.

[0059] Optionally, the workbench unit 8 further includes a first cable chain 82 and a second cable chain 83. One end of the first cable chain 82 is connected to the workbench 81, and the other end is connected to the first support plate 12. One end of the second cable chain 83 is connected to the second fixed plate 23, and the other end is connected to the third support plate 32. Since the first adjustment unit 1, the second adjustment unit 2, the third adjustment unit 3, and the fourth adjustment unit 4 all have moving cables, hydraulic pipes, air pipes, and other media pipes, the first cable chain 82 and the second cable chain 83 can effectively protect these media pipes, preventing them from being worn, pulled, or collided during movement, thus ensuring stable operation of the equipment.

[0060] Optionally, the welding unit 5 further includes a first clamping plate 52 and a second clamping plate 53. The first clamping plate 52 is connected to the fourth support plate 42 and has a first groove. The second clamping plate 53 has a second groove and is detachably connected to the first clamping plate 52. The first groove and the second groove together form a clamping cavity for accommodating the welding torch 51. By using the detachable first clamping plate 52 and the second clamping plate 53 to clamp the welding torch 51, it is possible to disassemble and assemble the welding torch 51 at any time, facilitating maintenance and replacement. The shapes of the first groove and the second groove are adapted to the shape of the welding torch 51. In this embodiment, the rod of the welding torch 51 is circular, so both the first groove and the second groove are semi-circular grooves.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
