Description

Technical Field

[0001] The present invention relates to a welding tooling, specifically a welding tooling applicable to an aluminum welder. Background Art

[0002] An aluminum welder is a process equipment that melts aluminum and aluminum alloy materials through heating or pressurization to achieve a bonding effect. During the fusion process, welding wires or metal fillers can be used, or the two workpieces can be self-fused, so that the molecules at the fusion joint of the two workpieces penetrate each other to form a permanent connection.

[0003] In the existing aluminum welder, during the welding process, the welder holds the welding torch in one hand and the welding wire in the other hand. When welding, the welder uses one finger to push the welding wire forward with one hand and drives the welding torch to move along the weld with the other hand. This requires high experience of the welder. For those with low experience, welding aluminum blocks is likely to cause uneven thickness of the weld beads, cracks, slag inclusion, porosity and other defects, affecting the welding quality. Summary of the Invention

[0022] Preferably, second adjusting sliders are slidably provided at both ends of the first bottom rod and the second bottom rod on the base. The bidirectional lead screw passes through the second adjusting sliders and forms a rotational connection with the second adjusting sliders.

The base block can slide outward away from the base along a certain inclination angle to offset the ablation amount after the wire is welded, ensuring that the wire moves along the weld of the aluminum block while maintaining the height distance between the bottom of the wire and the aluminum block. By driving the base block to slide with a small motor and arranging a wire groove on the slide rail, the interference of the slide rail on the movement of the wire is avoided while ensuring the uniform movement of the wire, guaranteeing the movement space of the wire. The uniform movement of the wire replaces the manual movement and pushing of the wire, which helps welders with less experience to weld higher-quality weld beads. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Embodiment

[0040] Refer to Figure 1 : A welding tooling applicable to an aluminum welder, including a base 1. A first clamping seat and a second clamping seat 3 for clamping the front and rear sides of an aluminum block are provided on the base 1. Sliding blocks 4 are provided at the bottoms of the first clamping seat 2 and the second clamping seat 3. A slide groove 5 for the two sliding blocks 4 to slide is provided at the top of the base 1. A bi-directional lead screw 6 is rotatably provided on the base 1. The two sliding blocks 4 (refer to Figure 2 ) are symmetrically arranged on both sides of the bi-directional lead screw 6 and are in threaded connection with the bi-directional lead screw 6; clamping assemblies and side plates 7 for clamping the left and right sides of the aluminum block are provided on both sides of the top of the base 1. Two groups of aluminum blocks to be welded are placed between the first clamping seat 2 and the second clamping seat 3, and one side of the two groups of aluminum blocks abuts against the side plate 7 at the same time for alignment. By rotating the bi-directional lead screw 6, the first clamping seat 2 and the second clamping seat 3 are driven to move towards each other to clamp the two groups of aluminum blocks. The side plate 7 and the clamping assembly can limit the left and right positions of the two groups of aluminum blocks on the first clamping seat 2 and the second clamping seat 3;

[0041] Such as Figure 2As shown, the first clamping seat 2 includes a first bottom rod 202 and a first placing rod 201, and the second clamping seat 3 includes a second bottom rod 302 and a second placing rod 301. The first placing rod 201 is disposed on one side of the first bottom rod 202 close to the second bottom rod 302. A plurality of groups of the first placing rods 201 are uniformly arranged along the length direction of the first bottom rod 202. The second placing rod 301 is disposed on one side of the second bottom rod 302 close to the first bottom rod 202 and a plurality of groups are uniformly arranged along the length direction of the second bottom rod 302. The first placing rods 201 and the second placing rods 301 are arranged in an alternating manner adjacent to each other. On the end faces of the adjacent first placing rods 201 close to each other, stable grooves 34 are provided. One end of the second placing rod 301 is provided with a stable block 35 that is snapped into the stable groove 34. When the first clamping seat 2 and the second clamping seat 3 slide towards each other to clamp two groups of aluminum blocks, the overlapping portion between the first placing rod 201 and the second placing rod 301 will increase, reducing the space occupied by the first clamping seat 2 and the second clamping seat 3.

On one side of the second bottom rod 302 close to the first bottom rod 202, a second T-shaped groove is provided. One end of the sliding section has a T-shaped cross-section and is slidably disposed in the second T-shaped groove. On the first bottom rod 202, a mating groove 53 for the connecting section to extend out is provided. The side plate 7 slides between the first bottom rod 202 and the second bottom rod 302 through the cooperation of the second T-shaped groove and the mating groove 53. The side plate 7 can be slid according to the distance at which the aluminum blocks to be welded need to be placed on the clamping assembly, facilitating the joint positioning of the position of the aluminum blocks to be welded by the clamping assembly and the side plate 7.

The other end of the connecting section is provided with a second connecting hole and a positioning groove for the rubber plug 36 of the next connecting section to insert. The sizes of the welded aluminum blocks in different batches are different. After the first clamping seat 2 and the second clamping seat 3 clamp the aluminum blocks, the length of the side plate 7 extending out of the first clamping seat 2 is different. By disassembling an appropriate number of connecting sections, it is possible to prevent the side plate 7 from protruding too much from the first clamping seat 2. On one side of the second T-shaped groove, a through groove 52 runs through the second bottom rod 302. A second tightening bolt 37 is threadedly connected to one end of the sliding section located in the through groove 52. The second tightening bolt 37 is slidably disposed in the through groove 52.
