Description
Technical Field
[0001] This invention relates to the field of metal component processing technology, and in particular to an adaptive multi-angle welding positioning device. Background Technology
[0002] In the field of metal processing and welding, the positioning accuracy of the workpiece before welding directly determines the quality of the final weld and the dimensional accuracy of the component.
[0003] In traditional welding operations, operators often rely on manually supporting the workpiece for positioning. This method has significant limitations in practical applications: on the one hand, manual support can easily cause the workpiece to loosen or shift due to operator fatigue or movement, making it difficult to maintain positioning stability; on the other hand, conventional fixed fixtures are mostly designed with a single angle, which cannot adapt to the need for flexible angle adjustment for different welding joint types (such as right angle and oblique angle). Each time the angle is changed, a special fixture often needs to be replaced, which is cumbersome and inefficient, affecting the consistency of welding operations and production efficiency. Summary of the Invention
[0004] The purpose of this invention is to provide an adaptive multi-angle welding positioning device to overcome the shortcomings in the aforementioned background technology.
[0005] The technical solution of the present invention is: an adaptive multi-angle welding positioning device, which includes a support platform and a first limiting member, a second limiting member, and a transverse driving member disposed thereon. The first limiting member and the second limiting member each have a positioning surface for positioning the workpiece, and the positioning surfaces of the two are facing each other and the tilt angle is adjustable. The positioning surface of the first limiting member is provided with an opening structure for the workpiece to extend along its positioning surface. The execution end of the transverse driving member is connected to the second limiting member and is used to drive the second limiting member to move transversely relative to the first limiting member.
[0006] Preferably, the first limiting member includes a first limiting arm and a second limiting arm spaced apart. The proximal ends of the first limiting arm and the second limiting arm are independently rotatably connected to the support platform via a first rotating shaft, and the disjoint ends are independently connected to the support platform via a first adjusting member. The axis of the first rotating shaft is perpendicular to the lateral movement direction of the second limiting member.
[0007] Preferably, the support platform is provided with an arc-shaped guide groove centered on the first rotating shaft, and the first adjusting member includes a positioning bolt that passes through the arc-shaped guide groove and connects to the first limiting member.
[0008] Preferably, the lateral movement drive includes a drive rod, a first mounting base, and a second mounting base. The first mounting base is fixed to the support platform. One end of the drive rod passes through and is threaded to the first mounting base, and the other end is rotatably connected to the second mounting base. The second mounting base is disposed between the first mounting base and the first limiting member, and is slidably connected to the support platform. The second limiting member is movably connected to the second mounting base.
[0009] Preferably, the second limiting member includes a third limiting arm and a fourth limiting arm. The proximal ends of the third limiting arm and the fourth limiting arm are independently rotatably connected to the second mounting base via a second rotating shaft, and the disjoint ends are connected to the drive rod via a second angle adjusting member. The axis of the second rotating shaft is perpendicular to the lateral movement direction of the second limiting member.
[0010] Preferably, the second adjusting member includes a sliding sleeve, a connecting rod, and an inner threaded sleeve. The inner threaded sleeve is located between the first mounting base and the second mounting base, and the driving rod passes through and is threaded onto the inner threaded sleeve. The sliding sleeve is located between the inner threaded sleeve and the second mounting base, and is slidably sleeved outside the driving rod. One end of the connecting rod is rotatably connected to the sliding sleeve, and the other end is rotatably connected to the third limiting arm or the fourth limiting arm.
[0011] Preferably, the support platform is provided with a straight guide groove, which extends along the lateral movement direction of the second limiting member. The second mounting base includes a sliding part and a supporting part. The sliding part is at least partially located in the straight guide groove and slides in cooperation with the straight guide groove. The supporting part is located outside the straight guide groove and is connected to the drive rod.
[0012] Preferably, the end of the drive rod away from the second limiting member is provided with a drive handle, and the outer diameter of the drive handle is larger than the diameter of the drive rod.
[0013] Preferably, the support platform is provided with a processing groove, which corresponds to the position of the opening structure and is recessed from the side edge of the support platform toward the center.
[0014] The beneficial effects of this invention include: by using the first and second limiters with adjustable tilt angles, in conjunction with the lateral drive, the problem of easy loosening and displacement in traditional manual support positioning is effectively overcome, and stable clamping of the workpiece is achieved during the welding process; at the same time, the device can flexibly adapt to different welding angle requirements, and can complete the positioning of various joint types such as right angle and oblique angle without changing the fixture, which significantly improves the adjustment efficiency and operation convenience of welding operations, and ensures the consistency of welding quality and dimensional accuracy.

[0026] The technical solutions of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0027] In the description of the embodiments of this invention, it should be understood that the terms "top," "bottom," etc., indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, 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, and therefore should not be construed as a limitation of the invention. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this invention through specific circumstances.
[0028] Reference Appendix Figure 1-4This invention provides an adaptive multi-angle welding positioning device, which includes a support platform 1, a first limiting member 2, a second limiting member 3, and a transverse drive member 4. The first limiting member 2, the second limiting member 3, and the transverse drive member 4 are disposed on the support platform 1. According to processing requirements, the bottom of the support platform 1 can be provided with legs 5 of appropriate height. The first limiting member 2, the second limiting member 3, and the transverse drive member 4 are arranged sequentially. The first limiting member 2 and the second limiting member 3 respectively have positioning surfaces for positioning workpiece 6, and the positioning surfaces of the two are facing each other and the tilt angle is adjustable. The positioning surface of the first limiting member 2 has an opening structure for the workpiece 6 to extend along its positioning surface. The execution end of the transverse drive member 4 is connected to the second limiting member 3 and is used to drive the second limiting member 3 to move transversely relative to the first limiting member 2, changing the distance between the positioning surfaces of the two, thereby clamping the workpiece 6 to be processed or releasing the processed workpiece 6.
[0029] In use, the operator first adjusts the tilt angle of the first limiting member 2 according to the welding angle requirements, and places the workpiece 6 to be welded between the positioning surfaces of the first limiting member 2 and the second limiting member 3. Depending on the type of welding joint, the workpiece 6 can extend out from the opening structure of the first limiting member 2 or be completely placed between its positioning surfaces. Then, the operator operates the transverse drive 4 to drive the second limiting member 3 to move towards the first limiting member 2, while simultaneously adjusting the tilt angle of the second limiting member 3 until the workpiece 6 is reliably clamped, at which point the welding operation can begin. This device has a simple structure, taking into account both the flexibility of welding angle and the stability of workpiece 6 clamping, effectively improving the accuracy of welding positioning and operational efficiency.
[0030] As a specific implementation of the opening structure, the first limiting member 2 includes a first limiting arm 21 and a second limiting arm 22 spaced apart from each other. The two arms are distributed at an angle and maintain a distance between their near ends, which constitutes the opening structure. The near ends of the first limiting arm 21 and the second limiting arm 22 are independently rotatably connected to the support platform 1 via different first rotating shafts 23, and the axis of the first rotating shaft 23 is perpendicular to the lateral movement direction of the second limiting member 3. The far ends of the first limiting arm 21 and the second limiting arm 22 are independently connected to the support platform 1 via different first angle adjusting members 24. When adjusting the angle, the first angle adjusting member 24 is first loosened so that the first limiting arm 21 and the second limiting arm 22 can rotate independently around their respective first rotating shafts 23, thereby changing their included angle to adapt to different welding angles. After adjustment, the first angle adjusting member 24 is tightened to lock the far ends of the first limiting arm 21 and the second limiting arm 22 onto the support platform 1, thereby fixing their included angle and completing the angle adjustment and locking process.
[0031] In practical welding applications, the workpieces 6 to be welded typically include profiles with parallel surfaces such as square steel pipes, flat steel, and flat iron, as well as rotating workpieces 6 such as round steel pipes. During welding, it is usually necessary for the positioning surfaces on both sides of the same workpiece 6 to be parallel. In this solution, the inclination angles of the first limiting member 2 and the second limiting member 3 can be adjusted independently, so that their positioning surfaces can be adjusted to a parallel state and maintain a uniform and stable fit with the surface of the workpiece 6 when clamped, so as to meet the positioning requirements of the above-mentioned workpieces 6 during welding.
[0032] Specifically, the support platform 1 is provided with an arc-shaped guide groove 11 centered on the first rotating shaft 23. The first adjusting member 24 includes a positioning bolt that passes through the arc-shaped guide groove 11 and connects the first limiting arm 21 and the second limiting arm 22. The positioning bolt can be locked in two ways: First, the positioning bolt is threadedly connected to the first limiting arm 21 or the second limiting arm 22. When tightened, the bolt head forms a clamping force between the bottom surface of the support platform 1 and the first limiting arm 21 (or the second limiting arm 22) and the top surface of the support platform 1, thereby locking the first limiting arm 21 (or the second limiting arm 22); Second, after the positioning bolt passes through the arc-shaped guide groove 11 and the first limiting arm 21 (or the second limiting arm 22) in sequence, it is threadedly engaged with the nut. When the nut is tightened, the first limiting arm 21 (or the second limiting arm 22) and the support platform 1 can also be pressed together to achieve the purpose of locking.
[0033] Reference Appendix Figure 1 The lateral movement drive component 4 includes a drive rod 41, a first mounting base 42, and a second mounting base 43. The first mounting base 42 is fixed to the support platform 1. One end of the drive rod 41 passes through and is threaded to the first mounting base 42, while the other end is rotatably connected to the second mounting base 43. The second mounting base 43 is located between the first mounting base 42 and the first limiting member 2, and is slidably connected to the support platform 1. The second mounting base 43 and the second limiting member 3 are movably connected. When the drive rod 41 is rotated, it generates axial displacement through its threaded engagement with the first mounting base 42, thereby directly or through the second mounting base 43 driving the second limiting member 3 to move laterally relative to the first limiting member 2.
[0034] To ensure smoother and more reliable lateral movement, the support platform 1 is provided with a straight guide groove 12 extending along the lateral movement direction of the second limiting member 3. The second mounting base 43 includes a sliding part 431 and a support part 432. The sliding part 431 is at least partially embedded in the straight guide groove 12 and slides against the groove wall to limit its movement trajectory and reduce sway. The support part 432 is located outside the straight guide groove 12 and is connected to the drive rod 41 to transmit the axial thrust of the drive rod 41. Through the cooperation between the sliding part 431 and the straight guide groove 12, the second mounting base 43 moves smoothly along a predetermined direction under the action of the drive rod 41, thereby driving the second limiting member 3 to achieve precise and stable lateral positioning.
[0035] In addition, in this embodiment, a drive handle 44 is provided at the end of the drive rod 41 away from the second limiting member 3. The outer diameter of the drive handle 44 is larger than the diameter of the drive rod 41. On the one hand, the drive handle 44 can provide a larger operating lever arm, making it easier for the user to apply force to rotate. On the other hand, when the drive rod 41 is screwed into the limit position, the drive handle 44 abuts against the end face of the first mounting base 42, which can prevent the drive rod 41 from being screwed in further.
[0036] Reference Appendix Figure 1 The second limiting member 3 includes a third limiting arm 31 and a fourth limiting arm 32. The proximal ends of the third limiting arm 31 and the fourth limiting arm 32 are independently rotatably connected to the second mounting base 43 via the second rotating shaft 34, and the disjoint ends are connected to the drive rod 41 via the second adjusting member 33. The axis of the second rotating shaft 34 is perpendicular to the lateral movement direction of the second limiting member 3.
[0037] More specifically, the second adjusting member 33 includes a sliding sleeve 331, a connecting rod 332, and an inner threaded sleeve 333. The inner threaded sleeve 333 is located between the first mounting base 42 and the second mounting base 43, and the driving rod 41 passes through and is threaded onto the inner threaded sleeve 333. The sliding sleeve 331 is located between the inner threaded sleeve 333 and the second mounting base 43, and is slidably sleeved outside the driving rod 41. One end of the connecting rod 332 is rotatably connected to the sliding sleeve 331, and the other end is rotatably connected to the third limiting arm 31 or the fourth limiting arm 32. When the inner threaded sleeve 333 is rotated toward the second mounting base 43, the inner threaded sleeve 333 pushes the sliding sleeve 331 to move axially along the drive rod 41, and then pushes the third limiting arm 31 and the fourth limiting arm 32 to rotate around the second rotating shaft 34 through the connecting rod 332 until the positioning surfaces of the two arms are flat and pressed against the surface of the workpiece 6. At this time, the third limiting arm 31 and the fourth limiting arm 32 cannot continue to rotate due to the obstruction of the workpiece 6, and the sliding sleeve 331 cannot continue to move toward the first limiting member 2. Furthermore, due to the limitation of the inner threaded sleeve 333, the sliding sleeve 331 cannot move toward the drive handle 44, thereby achieving adaptive clamping of the workpiece 6.
[0038] Based on the synchronous linkage structure achieved by the third limiting arm 31 and the fourth limiting arm 32 through the second angle adjusting member 33, it can be seen that after clamping, the third limiting arm 31 and the fourth limiting arm 32 are symmetrical about the drive rod 41. Correspondingly, the first limiting arm 21 and the second limiting arm 22 are also symmetrically arranged relative to the drive rod 41. Although the angles of the two can be independently adjusted by different first angle adjusting members 24 and first rotating shafts 23, this design mainly serves the flexibility of operation.
[0039] To facilitate the processing operation when the workpiece 6 extends out, the support table 1 is provided with a processing groove 13 corresponding to the position of the opening structure of the first limiting member 2. The processing groove 13 is recessed from the side edge of the support table 1 toward the center of the table surface, thereby providing operating space for the area below the workpiece 6 when it extends out of the opening structure, and avoiding interference with the support table 1.
[0040] In practical implementation, the materials and structure of the first limiting arm 21, the second limiting arm 22, the third limiting arm 31 and the fourth limiting arm 34 can be flexibly adapted to the construction site conditions. For example, common profiles such as standard angle steel and square steel can be used for rapid processing and assembly, so as to meet the functional requirements while taking into account the practicality and on-site adaptability of the device, and making it easy to manufacture and maintain.
[0041] Compared with the prior art, the beneficial effects of the technical solution of the present invention include at least the following: by using the first limiting member 2 and the second limiting member 3 with adjustable tilt angle, in conjunction with the transverse driving member 4, the problem of easy loosening and displacement of traditional manual support positioning is effectively overcome, and the workpiece 6 is stably clamped during the welding process; at the same time, the device can flexibly adapt to different welding angle requirements, and can complete the positioning of various joint types such as right angle and oblique angle without changing the fixture, which significantly improves the adjustment efficiency and operation convenience of welding operations, and ensures the consistency of welding quality and dimensional accuracy.
[0042] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
