Abstract
Description
Technical Field
[0001] This utility model belongs to the field of welding tooling technology, specifically relating to a universal tooling for welding CCS nickel sheets and aluminum busbars. Background Technology
[0002] During the production process, in order to meet the requirements of normal production on the working face, it is necessary to press the nickel sheet onto the surface of the aluminum busbar through a hollow copper nozzle to prevent problems such as incomplete welding or off-center welding during welding.
[0003] The tooling currently used is traditional dedicated tooling, which uses fixed copper nozzles and material placement fixtures (the copper nozzles correspond to the nickel sheet pressing positions). This type of tooling is fixed, and there is a one-to-one relationship between the welding product model and the tooling. Since the pressing positions of the nickel sheets and the size of the CCS base are different for different models, this fixed tooling cannot be used for other models. Once damaged, the entire tooling needs to be replaced. In addition, when producing multiple models of CCS, multiple dedicated toolings need to be prepared, which occupies storage space, is inconvenient to manage, is cumbersome to change models, and is relatively expensive. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, this utility model provides a universal tooling for welding CCS nickel sheets and aluminum busbars, which solves the technical problem that fixed copper nozzles are difficult to adapt to welding CCS nickel sheets of different positions and sizes.
[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:
[0006] A universal tooling for welding CCS nickel sheets to aluminum busbars includes a welding limiting tooling, a support frame, and multiple copper nozzle assemblies. The welding limiting tooling is used to limit and clamp the workpieces to be welded. The support frame is mounted directly above the welding limiting tooling and can be switched between being close to or far from the welding limiting tooling.
[0007] Each copper nozzle assembly is slidably connected to the support frame, allowing it to slide along the length of the support frame and lock when it reaches a designated position. Each copper nozzle assembly has a firing channel.
[0008] Furthermore, the support frame has multiple mounting grooves sequentially formed to mate with the copper nozzle assembly. These mounting grooves are spaced apart on the support frame. Each end of the copper nozzle assembly connects to two adjacent mounting grooves, thus achieving a sliding fit between the copper nozzle assembly and the support frame.
[0009] Furthermore, the welding limiting fixture includes a welding platform and two limiting blocks. The two limiting blocks are arranged sequentially along the length of the welding platform, and the distance between them can be adjusted to achieve the clamping and fixing of the welded parts of corresponding dimensions.
[0010] Furthermore, the two limiting blocks are divided into a first block fixed to the welding platform and a second block slidably connected to the welding platform. The second block is provided with a locking element for locking its relative position with the welding platform when the second block slides to a designated position.
[0011] Furthermore, the second locking block has a stepped first clearance groove. The locking member is disposed within the first clearance groove, and its bottom passes through the first clearance groove. The welding platform has a plurality of threaded holes that mate with the locking member. The bottom of the locking member is threadedly engaged with the threaded holes.
[0012] Furthermore, the first clearance groove is a long strip-shaped groove, and its length direction is the same as the sliding direction of the second block.
[0013] Furthermore, a stop is provided on the long edge of the welding platform. The stop slides with the welding platform, can move along the width direction of the welding platform, and can lock when it slides to a designated position.
[0014] Furthermore, the stop block has a second clearance groove, and the length direction of the second clearance groove is the same as the width direction of the welding platform. A fastener is installed in the second clearance groove. The bottom of the fastener passes through the second clearance groove and is threadedly connected to the welding platform.
[0015] Furthermore, the copper nozzle assembly includes a copper nozzle body, a mounting base, and a locking component. The mounting base is slidably connected to the support frame. The bottom of the locking component passes through a mounting groove and is threadedly connected to the mounting base. The copper nozzle body is mounted on the mounting base.
[0016] Furthermore, the copper nozzle body is slidably connected to the mounting base, allowing it to move vertically. Multiple positioning pins are fixed to the copper nozzle body. The mounting base has positioning holes that mate with each positioning pin. Each positioning pin slidably engages with its corresponding positioning hole. A return spring is fitted around the outer ring of each positioning pin.
[0017] Compared with the prior art, the present invention has the following advantages:
[0018] This invention features a sliding fit between the copper nozzle assembly and the support frame, with a locking element between them. By tightening or loosening the locking element, the relative position of the copper nozzle assembly and the support frame can be locked or unlocked. This allows the copper nozzle assembly to be adjusted according to the size of the CCS nickel sheet and the required welding position, making it suitable for welding various types of CCS. This reduces the labor costs required to replace copper nozzle assemblies of different sizes and positions, as well as the cost of manufacturing copper nozzle assemblies of various sizes and positions.

Therefore, they should not be construed as limitations on this utility model.
[0025] The present invention will be further described below with reference to the accompanying drawings.
[0026] like Figure 1 As shown, a universal tooling for welding CCS nickel sheets to aluminum busbars includes a welding limiting tooling 1, a support frame 2, a cylinder, and multiple copper nozzle assemblies 3. The welding limiting tooling 1 can clamp and limit the workpiece 6 to be welded. The support frame 2 is mounted directly above the welding limiting tooling 1 and can switch between approaching and moving away from the welding limiting tooling 1 under the drive of the cylinder. Each copper nozzle assembly 3 is slidably connected to the support frame 2, can slide along the length of the support frame 2, and locks when it reaches a designated position. The copper nozzle assembly 3 has an emission channel. The laser can be emitted through the emission channel to a designated area of the workpiece 6 to complete the welding process.
[0027] The specific structure is as follows: Figure 2As shown, the support frame 2 has multiple mounting grooves 4 that mate with the copper nozzle assembly 3. These mounting grooves 4 are spaced apart on the support frame 2. Each end of the copper nozzle assembly 3 connects to two adjacent mounting grooves 4, thus achieving a sliding fit between the copper nozzle assembly 3 and the support frame 2. An observation groove 5 is provided between adjacent mounting grooves 4, allowing workers to directly observe the welding process.
[0028] like Figure 3 As shown, the copper nozzle assembly 3 includes a copper nozzle body 3-1, a mounting base 3-2, and a locking screw. The mounting base 3-2 is slidably connected to the support frame 2. The bottom of the locking screw passes through the mounting groove 4 and is threadedly connected to the mounting base 3-2, locking the mounting base 3-2 in a designated position on the support frame 2 when tightened, and unlocking it when loosened, allowing it to slide on the support frame 2. The copper nozzle body 3-1 is mounted on the mounting base 3-2. Both the copper nozzle body 3-1 and the mounting base 3-2 have a laser emission port and a clearance through-hole, respectively. The laser emission port and the clearance through-hole are interconnected, forming a laser emission channel.
[0029] Furthermore, the copper nozzle body 3-1 is slidably connected to the mounting base 3-2, allowing it to move vertically. Multiple positioning pins 3-3 are fixed to the copper nozzle body 3-1. The mounting base 3-2 has positioning holes that mate with each positioning pin 3-3. Each positioning pin 3-3 slides into its corresponding positioning hole. A return spring is fitted around the outer ring of each positioning pin 3-3.
[0030] During processing, as the copper nozzle body 3-1 descends to contact the workpiece 6 and continues to descend, it applies pressure to the workpiece 6, confining it to the welding limiting fixture 1. Simultaneously, the return spring is compressed due to the movement of the copper nozzle body 3-1. When the copper nozzle body 3-1 rises, the return spring pushes it back to its original position.
[0031] like Figure 4 As shown, the welding limiting fixture 1 includes a welding platform 1-1 and two limiting blocks. The welding platform 1-1 has a limiting groove 1-4 that mates with the limiting blocks. The two limiting blocks are a first block 1-2 fixed within the limiting groove 1-4, and a second block 1-3 slidably connected within the limiting groove 1-4. Slots are formed on the opposite sides of the first block 1-2 and the second block 1-3. The two slots together form a limiting groove that limits the length of the workpiece 6 to be welded.
[0032] Furthermore, the second locking block 1-3 has a stepped first clearance groove. A locking screw is installed in the first clearance groove. The limiting slide 1-4 has multiple threaded holes that mate with the locking screw. The bottom of the locking screw passes through the first clearance groove and can engage with the threaded holes on the limiting slide 1-4, thereby locking or unlocking the position of the limiting locking block.
[0033] Furthermore, the first clearance groove is a long strip-shaped groove, and its length direction is the same as the sliding direction of the second locking block 1-3, so that when the locking screw is aligned with the corresponding threaded hole, the second locking block 1-3 can be adjusted secondary through the first clearance groove.
[0034] In practical use, the first locking block 1-2 and the second locking block 1-3 are adjusted to the specified spacing according to the length of the welded part 6. The locking screw on the second locking block 1-3 is initially connected to the corresponding threaded hole. The welded part 6 is installed between the two limiting locking blocks. The second locking block 1-3 is adjusted a second time through the clearance groove until the corners on both sides of the welded part 6 are embedded in the locking grooves of the first locking block 1-2 and the second locking block 1-3, thus completing the limiting of the welded part 6.
[0035] In addition, in this embodiment, a stop (not shown in the figure) is provided on the long edge of the welding platform 1-1. The stop is slidably engaged with the welding platform 1-1, can move along the width direction of the welding platform 1-1, and can be locked when it slides to a designated position.
[0036] The specific structure is as follows: a second clearance groove is provided on the stop block, and the length direction of the second clearance groove is the same as the width direction of the welding platform 1-1. A fastening screw is provided in the second clearance groove. The bottom of the fastening screw passes through the second clearance groove and is threadedly connected to the welding platform 1-1.
[0037] When the position of the welded part 6 is limited, the fastening screw is loosened so that the stop can move along the width direction of the welding platform 1-1, thereby limiting the position of the welded part 6 in the width direction.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
