Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding tooling technology, and in particular to a positioning welding tooling. Background Technology
[0002] In modern industrial manufacturing, ring-shaped corrugated wires are widely used in many industries such as automotive parts, electronics, and aerospace. The welding quality of these wires directly affects the performance and lifespan of the products. However, due to the flexibility and complex corrugated structure of the wires themselves, problems such as misalignment and angular deviation at both ends often exist before welding, leading to defects such as incomplete welds and stress concentrations after welding.
[0003] Currently, the common method involves manual positioning combined with simple clamping. Operators first roughly align the two ends of the notch in the ring-shaped corrugated wire based on experience, then use ordinary clamps to hold and fix the wire. This positioning method relies heavily on the operator's skill and experience, making it difficult to guarantee accuracy and consistency every time. Furthermore, during clamping, the mating parts at the two ends of the wire notch are prone to misalignment and movement, leading to deviations in the shape and size of the wire after welding, as well as incomplete welds, resulting in lower product yield and increased manufacturing costs. Therefore, there is an urgent need for a new alignment and welding fixture to solve these problems. Utility Model Content
[0004] To overcome the shortcomings of the prior art, this utility model provides a positioning welding fixture, which solves the technical problem that misalignment and angular displacement occur during welding of the butt joint of annular waveform wires, making it difficult to guarantee the consistency of the butt joint positioning.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0006] A positioning welding fixture for positioning and butt welding of annular corrugated wires before welding includes:
[0007] The system includes a track and a pair of clamping assemblies. The pair of clamping assemblies is mounted on the track and is movable and adjustable in the extension direction of the track. The annular waveform wire includes an annular body with a notch. Each clamping assembly includes a clamp seat and a pressure plate. The pressure plate is detachably mounted on the clamp seat, and the clamp seat has a receiving groove for accommodating the two ends of the annular body near the notch. Each pair of clamp seats has a first notch on opposite sides. The first notch penetrates the pressure plate in the vertical direction and is connected to the receiving groove. When the two ends of the annular body near the notch are located in the receiving groove, the distance between the pair of clamping assemblies is adjusted so that the two ends of the annular body near the notch are aligned with the pair of clamping assemblies.
[0008] A locking component for limiting the clamping assembly on the track.
[0009] Based on the above structure, the principle of the aforementioned alignment welding fixture is as follows: First, according to the length of the notch in the annular corrugated wire, the spacing of a pair of clamping components is adjusted along the track to ensure that they are aligned with the two ends of the notch. Next, the two ends of the notch on the annular body are placed into the grooves on the two clamps, the grooves being adapted to the shape of the annular corrugated wire. Then, a pressure plate is installed on the clamps, pressing against the grooves to limit the annular corrugated wire. The grooves restrict the horizontal displacement of the annular corrugated wire, while the pressure plate provides vertical pressure to prevent the annular corrugated wire from warping due to vibration or thermal deformation during welding. Reliable positioning is achieved. Next, the distance between a pair of clamps is adjusted so that the two ends of the annular body near the notch align with a pair of clamping components. The locking component is adjusted to limit the clamping components on the track. Finally, the mating position is welded. The clamping components have an adjustable movement function along the track, which, through sliding and locking, adapts to annular waveform wires of different diameters. The first notch passes through the pressure plate in the vertical direction, and the space formed provides clearance for the waveform part of the annular waveform wire, preventing deformation of the annular waveform wire. The pressure plate is designed to be detachable for quick disassembly, facilitating the installation of the annular waveform wire to be welded or its removal after welding.
[0010] Furthermore, in one alignment welding fixture of this application, the clamping assembly further includes: a base, the base having a second notch adapted to the track, the second notch being used to accommodate the track, and the clamp being detachably mounted on the base. As a preferred embodiment of this application, the alignment welding fixture, through the cooperation of the second notch and the track, limits the base in the Y direction, ensuring the accuracy of the clamping assembly mounted on the track and the stability of its movement in the track's extension direction, thus avoiding positioning deviations; the detachable mounting of the clamp on the base facilitates the direct removal of the clamp and pressure plate from the base when the specifications and dimensions of the annular corrugated wire change, allowing for the replacement of clamps and pressure plates adapted to the annular corrugated wire, thereby improving the versatility of the welding fixture.
[0011] Furthermore, in one alignment welding fixture of this application, the locking component is a threaded locking component. A groove is provided on the track, the groove being arranged along the extension direction of the track. The locking component is disposed within the groove and is threadedly connected to the base. When the locking component locks the track and the base, it axially locks the track and the base, ensuring a tight fit between them axially. As a preferred embodiment of this application, in another alignment welding fixture, the locking component is used to limit the base, placing it in a limited or adjustable state. When the position of the base on the track needs adjustment, the locking component is released to separate the track and the base. After adjusting the base to a suitable position, the locking component is locked, and the track and the base are tightly fitted together, thus completing the limitation of the base.
[0012] Furthermore, in one alignment welding fixture of this application, the locking component includes a locking screw, the screw head of which is disposed in a countersunk groove, and the front end of which is threadedly connected to the base. As a preferred embodiment of this application, the locking component in the alignment welding fixture uses a locking screw to axially lock the track and base, thereby limiting the position of the clamping assembly.
[0013] Furthermore, in one alignment welding fixture of this application, a mounting plate is provided between the clamp and the base, and the clamp and the base are detachably connected to the mounting plate. As a preferred embodiment of this application, when welding annular corrugated wires of different specifications, the clamp can be removed from the mounting plate and replaced with a suitable clamp and pressure plate, thus improving the versatility of the welding fixture; when the clamp, base, or mounting plate is worn or damaged, the damaged parts can be replaced individually, avoiding the need for complete replacement and reducing maintenance costs.
[0014] Furthermore, in one alignment welding fixture of this application, a pair of third notches are provided on the side of the pressure plate away from the first notch. The pair of third notches are spaced apart in the Y direction, and each third notch is provided with a limiting screw. The limiting screw is threadedly connected to the clamp and is used to pre-tighten the pressure plate relative to the clamp. As a preferred embodiment of this application, in another alignment welding fixture, a pair of limiting screws are used to limit the pressure plate in the vertical direction. When it is necessary to remove the pressure plate from the clamp, the pressure plate moves laterally in the horizontal direction. At this time, the limiting screw slides from one end of the third notch to the other end, disengaging from the constraint area, and the pressure plate can be removed. This design facilitates the installation or removal of the annular corrugated wire and improves welding efficiency.
[0015] As can be seen from the above technical solution, this utility model has the following beneficial effects:
[0016] This utility model provides a positioning and welding fixture. Through the cooperation of a track and a movable and adjustable clamping assembly, the fixture utilizes a clamping seat groove, a pressure plate, and a special notch structure to achieve precise positioning and stable limiting of the annular waveform wire. During the welding process, the two ends of the annular body near the notch are always aligned between a pair of clamping assemblies, avoiding misalignment and angular displacement during welding, ensuring welding quality, improving product qualification rate, and reducing manufacturing costs. Furthermore, the fixture reduces manual operation steps during the positioning process, ensuring the accuracy and consistency of each positioning. Attached Figure Description

Detailed Implementation
[0022] like Figure 1 , 2 As shown in Figures 1 and 3, a positioning welding fixture is used for butt welding and positioning of the annular corrugated wire 1 before welding, comprising:
[0023] The system comprises: a track 2 and a pair of clamping components 3, the pair of clamping components 3 being mounted on the track 2 and movable and adjustable in the extension direction of the track 2; the annular waveform wire 1 comprising: an annular body 11, the annular body 11 having a notch 110; the clamping components 3 comprising: a clamping seat 31 and a pressure plate 32, the pressure plate 32 being detachably mounted on the clamping seat 31, the clamping seat 31 having a receiving groove 310 for accommodating the two ends of the annular body 11 near the notch 110; each of the opposite sides of the pair of clamping seats 31 having a first notch 311, the first notch 311 penetrating the pressure plate 32 in the vertical direction and communicating with the receiving groove 310; when the two ends of the annular body 11 near the notch 110 are located within the receiving groove 310, the distance between the pair of clamping components 3 is adjusted so that the two ends of the annular body 11 near the notch 110 are aligned between the pair of clamping components 3;
[0024] Locking component 4 is used to limit the clamping assembly 3 on the track 2.
[0025] Based on the above structure, the principle of the alignment welding fixture is as follows: First, according to the length of the notch 110 of the annular corrugated wire 1, the spacing of a pair of clamping components 3 is adjusted along the track 2 to ensure that the two are aligned with the two ends of the notch 110 respectively. Then, the two ends of the notch 110 on the annular body 11 are placed in the grooves 310 on the two clamps 31 respectively. The grooves 310 are adapted to the shape of the annular corrugated wire 1. Then, the pressure plate 32 is installed on the clamps 31, and the pressure plate 32 presses on the grooves 310 to limit the annular corrugated wire 1. The grooves 310 are used to limit the horizontal displacement of the annular corrugated wire 1, and the pressure plate 32 is used to provide vertical pressure to prevent the annular corrugated wire 1 from vibrating during the welding process. Alternatively, the wire may warp due to heat deformation to achieve reliable positioning. Next, the distance between a pair of clamps 31 is adjusted so that the two ends of the annular body 11 near the notch 110 are aligned with a pair of clamping components 3. The locking component 4 is adjusted to limit the clamping components 3 on the track 2. Finally, the alignment position is welded. The clamping components 3 have a sliding and locking function along the track 2 to adapt to annular waveform wires 1 with different diameters. The first notch 311 passes through the pressure plate 32 in the vertical direction, and the space formed provides clearance for the waveform part of the annular waveform wire 1, preventing deformation of the annular waveform wire 1. The pressure plate 32 is designed to be detachable for quick disassembly, facilitating the installation of the annular waveform wire 1 to be welded or its removal after welding.
[0026] In this embodiment, the clamping assembly 3 further includes a base 33, on which a second notch 330 adapted to the track 2 is provided. The second notch 330 is used to accommodate the track 2. The clamping seat 31 is detachably mounted on the base 33. This application provides a positioning welding fixture that, through the cooperation of the second notch 330 and the track 2, limits the position of the base 33 in the Y direction, ensuring the accuracy of the clamping assembly 3 mounted on the track 2 and the stability of its movement in the extension direction of the track 2, thus avoiding positioning deviations. The clamping seat 31 is detachably mounted on the base 33, facilitating the direct removal of the clamping seat 31 and pressure plate 32 from the base 33 when the specifications and dimensions of the annular waveform wire 1 change, allowing for replacement with clamping seats 31 and pressure plates 32 adapted to the annular waveform wire 1, thereby improving the versatility of the welding fixture. The clamping seat 31 is mounted on the base 33 by a pair of screws.
[0027] In this embodiment, as Figure 4 As shown, the locking component 4 is a threaded locking component. The track 2 has a recess 20, which is positioned along the extension direction of the track 2. The locking component 4 is located within the recess 20 and is threadedly connected to the base 33. When the locking component 4 locks the track 2 and the base 33, it axially locks the track 2 and the base 33, ensuring a tight fit between them. The locking component 4 limits the position of the base 33, placing it in a limited or adjustable state. When adjusting the position of the base 33 on the track 2, the locking component 4 is released to separate the track 2 and the base 33. After adjusting the base 33 to a suitable position, the locking component 4 is locked, ensuring a tight fit between the track 2 and the base 33, thus limiting the position of the base 33. The track 2 has a pair of recesses 20, spaced apart in the Y direction. Correspondingly, there are two locking components 4.
[0028] In this embodiment, the locking component 4 includes a locking screw 41, the screw head of which is disposed in the recess 20, and the front end of which is threadedly connected to the base 33. The locking component 4 uses the locking screw 41 to axially lock the track 2 and the base 33, and to limit the position of the clamping assembly 3.
[0029] In this embodiment, a mounting plate 34 is provided between the clamp 31 and the base 33, and the clamp 31 and the base 33 are detachably connected to the mounting plate 34. When it is necessary to weld different specifications of annular waveform wires 1, the clamp 31 can be removed from the mounting plate 34 and replaced with a suitable clamp 31 and pressure plate 32, thus improving the versatility of the welding fixture. When the clamp 31, base 33, or mounting plate 34 is worn or damaged, the damaged parts can be replaced individually, avoiding the need for complete replacement and reducing maintenance costs. The mounting plate 34 is connected to the base 33 and to the clamp 31 by a pair of screws.
[0030] In this embodiment, a pair of third notches 320 are provided on the side of the pressure plate 32 away from the first notch 311. The pair of third notches 320 are spaced apart in the Y direction. Each third notch 320 is provided with a limiting screw 6. The limiting screw 6 is threadedly connected to the clamp 31. The limiting screw 6 is used to pre-tighten the pressure plate 32 relative to the clamp 31. The pair of limiting screws 6 are used to limit the pressure plate 32 in the vertical direction. When it is necessary to remove the pressure plate 32 from the clamp 31, the pressure plate 32 moves laterally in the horizontal direction. At this time, the limiting screw 6 slides out from one end of the third notch 320 to the other end, disengaging from the constraint area, and the pressure plate 32 can be removed. This design facilitates the installation or removal of the annular waveform wire 1 and improves welding efficiency.
