Description

Technical Field

[0001] This utility model relates to the field of welding torch angle positioning technology, and in particular to an adjustable welding torch angle positioning mechanism. Background Technology

[0002] A welding torch is a tool used to join metal parts by heating them at high temperatures until they melt and then join them. It is widely used in welding processes. To adjust the angle of the welding torch according to different work requirements, thereby ensuring a stable operating posture during welding and reducing welding defects, an adjustable welding torch angle positioning mechanism is needed to improve welding efficiency and quality.

[0003] Traditional adjustable angle positioning mechanisms for welding torches mostly consist of multiple connecting rods. Connecting blocks are set between these connecting rods, and bolts are installed at the connection points between these connecting blocks and the adjusting rod to adjust the tightness of these parts. By rotating the bolts, the adjusting rod can be rotated. After rotating the adjusting rod to the appropriate angle, the bolts are then rotated to tighten this part, thus completing the angle adjustment.

[0004] The aforementioned positioning mechanism requires repeated tightening and loosening of bolts to adjust the angle of the welding torch, which is cumbersome and affects the work efficiency of the staff. Utility Model Content

[0005] Therefore, it is necessary to provide an adjustable welding torch angle positioning mechanism to address the problem of cumbersome adjustment process and its impact on work efficiency.

[0006] An adjustable welding torch angle positioning mechanism includes: a slide rail and a lifting adjustment mechanism slidably connected to the slide rail;

[0007] An angle adjustment mechanism includes a positioning block, a positioning rod rotatably connected to the inner wall of the positioning block, a driving block penetrating the top of the positioning rod inside the positioning block, and a vertical angle adjustment component below the positioning rod.

[0008] In one embodiment, two positioning rings are fixedly connected to the inner wall of the positioning block, and the positioning rod is rotatably connected to the positioning rings.

[0009] In one embodiment, the inner wall of the positioning rod is slidably connected with a plurality of friction blocks, the cross-section of the friction blocks is fan-shaped, the friction blocks are disposed between two positioning rings, and the driving block is used in conjunction with the plurality of friction blocks.

[0010] In one embodiment, the vertical angle adjustment assembly includes an adjustment block fixedly connected to the bottom end of the drive rod positioning rod, with a central shaft passing through the center of the adjustment block, and the central shaft being rotatably connected to the adjustment block.

[0011] In one embodiment, a clamp is mounted on one end of the central shaft, and a worm gear is fixedly connected to the surface of the other end of the central shaft.

[0012] In one embodiment, a worm is disposed above the worm wheel, and the worm meshes with the worm wheel.

[0013] In one embodiment, the adjusting block has a scale on the inner wall near the clamp, and a pointer is fixedly connected to the surface of the central shaft, which is used in conjunction with the scale.

[0014] In one embodiment, the lower half of the drive block is cylindrical-conical, and the upper half of the drive block is bolt-shaped.

[0015] Beneficial effects

[0016] 1. By setting a drive block between the positioning rod and the positioning block, and cooperating with multiple friction blocks to adjust the tightness of the positioning rod, the operator only needs to rotate the drive block slightly to complete the horizontal angle adjustment of the welding torch. Simultaneously, a worm gear structure is used for vertical angle adjustment. By rotating the worm, the welding torch angle can be shifted; stopping the rotation locks the welding torch position, simplifying the welding torch angle adjustment process. Compared to the traditional adjustment method of repeatedly loosening bolts, the new design greatly improves adjustment efficiency and simplifies operational complexity.

[0017] 2. By setting a scale inside the adjustment block and equipping it with a pointer on the central shaft surface, the pointer moves as the operator adjusts the vertical angle of the welding torch, displaying the current adjustment angle in real time. This design provides operators with a clear angle reference, ensuring the accuracy of angle adjustment. Visual guidance allows operators to make fine adjustments more easily, reducing angle errors caused by the lack of intuitive markings in traditional adjustment methods. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model 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 utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The following is combined with Figure 1 - Figure 5 This invention describes an adjustable welding torch angle positioning mechanism.

[0028] In one embodiment, an adjustable welding torch angle positioning mechanism includes: a slide rail 100 and a lifting adjustment mechanism 200 slidably connected to the slide rail 100.

[0029] Angle adjustment mechanism 300 includes a positioning block 310, a positioning rod 311 is rotatably connected to the inner wall of the positioning block 310, a drive block 312 is provided inside the positioning block 310 and penetrates the top of the positioning rod 311, and a vertical angle adjustment component 320 is provided below the positioning rod 311.

[0030] In this device, the slide rail 100 consists of a slide rail and a threaded rod disposed inside the slide rail. Both ends of the threaded rod are rotatably connected to the inside of the slide rail, and a handle is rotatably connected to one end of the slide rail. The handle passes through the slide rail and is fixedly connected to one end of the threaded rod. Both the upper and lower surfaces of the slide rail are provided with strip-shaped openings, and a connecting block is provided between the two strip-shaped openings. The connecting block is disposed on the surface of the threaded rod and is connected to the lifting adjustment mechanism 200. When the handle is turned, the handle drives the threaded rod to rotate, and the rotation of the threaded rod drives the connecting block to slide in the slide rail, thereby driving the lifting adjustment mechanism 200 to move as a whole, thereby driving the welding torch to move.

[0031] The lifting adjustment mechanism 200 consists of a slide groove fixedly connected to the connecting block and another threaded rod disposed in the slide groove. The surface of the threaded rod is provided with a lifting block, which is simultaneously slidably connected to the inner walls on both sides of the slide groove. The top end of the threaded rod passes through the slide groove and is fixedly connected to a knob. When the knob is rotated, the knob will drive the threaded rod to rotate, thereby raising and lowering the lifting block. The lifting block is fixedly connected to the positioning block 310, and the positioning block 310 moves synchronously with the lifting block.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, two positioning rings 3111 are fixedly connected to the inner wall of the positioning block 310, and the positioning rod 311 is rotatably connected to the positioning rings 3111. Multiple friction blocks 3112 are slidably connected to the inner wall of the positioning rod 311. The cross-section of the friction blocks 3112 is fan-shaped, and the friction blocks 3112 are disposed between the two positioning rings 3111. The driving block 312 works in conjunction with the multiple friction blocks 3112.

[0033] In this embodiment, the drive block 312 consists of four parts: a knob with anti-slip texture at the top, a threaded connecting rod in the second part, a smooth connecting rod in the third part, and a cylindrical cone at the bottom. The upper inner wall of the positioning block 310 and the top of the positioning rod 311 are provided with threads that cooperate with the second part. A through hole with a diameter larger than the bottom diameter of the drive block 312 is provided between the multiple friction blocks 3112. Therefore, when the drive block 312 moves down as a whole by rotating the knob, the multiple friction blocks 3112 are driven outward by the cylindrical cone at the bottom of the drive block 312 to apply pressure to the positioning block 310 and increase the friction. The positioning rod 311 is fixed inside the positioning block 310 by the friction. At the same time as the rotation, the operator needs to manually slightly limit the limit rod to reduce the angle error. Since the horizontal angle adjustment of the welding gun only adjusts the position of the welding gun and does not affect the vertical angle of the welding gun, the horizontal angle adjustment does not need to be too precise, while the vertical angle adjustment needs to be precise.

[0034] It should be noted that the adjustment mechanism of this device optimizes the traditional method of repeatedly turning the bolts to tighten or loosen the connecting parts, so that the adjustment can be completed by simply rotating the drive block 312 or rotating the worm gear 324. Moreover, this mechanism only acts on the position and adjustment of the welding torch and will not affect the connection method of the welding torch or the welding effect of the welding torch.

[0035] like Figure 2 , Figure 3 Figure 4 and Figure 5 As shown, the vertical angle adjustment assembly 320 includes an adjustment block 321 fixedly connected to the bottom end of the drive rod positioning rod 311. A central shaft 322 passes through the center of the adjustment block 321, and the central shaft 322 is rotatably connected to the adjustment block 321. A clamp 330 is installed at one end of the central shaft 322, and a worm gear 323 is fixedly connected to the surface of the other end of the central shaft 322. A worm 324 is provided above the worm gear 323, and the worm gear 324 meshes with the worm gear 323. A scale 340 is provided on the inner wall of the adjustment block 321 near the clamp 330, and a pointer 341 is fixedly connected to the surface of the central shaft 322. The pointer 341 is used in conjunction with the scale 340. The lower half of the drive block 312 is cylindrical and conical, and the upper half of the drive block 312 is bolt-shaped.

[0036] In this embodiment, the clamp 330 consists of two clamping blocks. The two clamping blocks are connected by bolts and nuts to compress and limit the welding torch. Since the clamp 330 does not require repeated adjustment after clamping the welding torch, it can be directly installed using bolts and nuts. The worm gear 323 and worm 324 are surrounded by a protective shell. The protective shell is fixedly connected to the side of the adjusting block 321 away from the furniture. A drive rod passes through and is fixedly connected to the center of the worm 324. One end of the drive rod is rotatably connected to the inner wall of the protective shell, and the other end passes through the protective shell and is fixedly connected to it. A knob is connected. When the knob is turned, it drives the worm gear 324 to rotate via the drive rod, which in turn drives the internal gear to rotate. When the worm wheel 323 rotates, it synchronously drives the central shaft 322 to rotate. The rotation of the central shaft drives the pointer 341 to move synchronously. The tilt angle of the welding torch can be determined by the scale 340 pointed to by the pointer 341. When the lead angle of the worm gear 324 is less than the equivalent friction angle between the meshing teeth, the mechanism has self-locking property and can achieve reverse self-locking. That is, only the worm gear 324 can drive the worm wheel 323, and the worm wheel 323 cannot drive the worm gear 324.

[0037] Working principle: Install this device in the preset position on the workbench, then adjust the slide rail 100 to move the welding gun horizontally to the appropriate position, then adjust the welding gun to the appropriate height through the lifting adjustment mechanism 200, and then position the angle of the welding gun through the angle adjustment mechanism 300.

[0038] When adjusting the angle, first rotate the drive block 312 to move it upward, thereby loosening the multiple friction blocks 3112 in the positioning rod 311, thus loosening the positioning rod 311. At this time, rotating the positioning rod 311 drives the welding torch to adjust the horizontal angle. After adjusting to the appropriate angle, rotate the drive block 312 in the opposite direction, and the drive block 312 moves downward. Its cylindrical cone part squeezes the multiple friction blocks 3112 outward along the limiting block. The outward expansion of the limiting block increases the pressure with the inner wall of the positioning block 310, thereby increasing the friction between the friction blocks 3112 and the inner wall of the positioning block 310, thus fixing the positioning rod 311.

[0039] Then, by rotating the worm gear 324, the worm gear 324 drives the worm wheel 323 to rotate. At the same time, the worm wheel 323 drives the central shaft 322 to rotate. The central shaft 322 drives the fixture 330 to rotate, thereby adjusting the vertical angle of the welding torch. During the adjustment process, the operator can judge the adjustment angle by observing the pointer 341 and the scale 340.

[0040] It should be noted that the slide rail 100, worm gear 323, worm 324 and clamp 330 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
