[0002] Light metal alloy welding refers to the welding process of light metal alloy materials. Light metal alloys have high strength and light weight. The main welding processes are manual TIG welding, automatic TIG welding and MIG welding. Light metal alloys have various shapes such as cylindrical and square. There are still some problems in the use of existing welding fixtures for processing light metal alloys. For example, the aluminum alloy welding fixture disclosed in publication number CN213003486U only uses springs to clamp the light metal alloy, which is not stable enough. To improve the clamping stability, bolts and other structures are generally used to close the clamping plates together.

In addition, after welding is completed, the push-pull frame can be pulled to realize the use of the right-angled triangle block on it to squeeze the push plate, thereby moving the mounting plates away from each other and releasing the light metal alloy. 2.

[0018] See also Figures 1-9 , the present invention provides the following technical solutions: Embodiment 1: In order to solve the problem that the previous welding tooling is cumbersome to operate when clamping light metal alloys, which is not conducive to improving welding efficiency, the following technical solution is provided, specifically, a welding tool for processing light metal alloys, including a support seat 1 and a limit groove 3 running through the upper and lower sides thereof, two limit seats 4 slidingly running through the limit groove 3, and the lower end protrusions of the two limit seats 4 are threaded with a screw rod 2, one end of the screw rod 2 is connected to the inner side surface of the support seat 1 with a bearing, and the other end of the screw rod 2 is passed through the outside of the support seat 1, the upper surface of the limit seat 4 is connected to the screw rod 2 5 with a bearing, and the screw rod 2 5 is threadedly connected to a sliding frame 6, and the upper end shaft of the sliding frame 6 is connected to a clamping seat 7. A push-type extrusion assembly is provided on the clamping seat 7, and the push-type extrusion assembly includes a mounting plate 21 for clamping a light metal alloy. The screw rod 2 is provided with two sections of threads that rotate in opposite directions, and the two sections of threads are respectively threadedly connected to the lower end protrusions of the two limit seats 4. A circular groove 30 is provided on the clamping seat 7, and the axis of the circular groove 30 is collinear with the rotation axis of the clamping seat 7. A worm gear 20 coaxial with the circular groove 30 is fixedly connected to the sliding frame 6, and a worm 8 is connected to the worm gear 20, and the bearing of the worm 8 extends to the outside of the clamping seat 7.

[0019] The push-type extrusion assembly also includes through grooves 10 on both sides of the clamping seat 7, and a push plate 15 is provided between the two through grooves 10 provided on each clamping seat 7. Both ends of the push plate 15 are fixedly connected to a sliding block 16, and the sliding block 16 is slidably connected to the clamping seat 7. Two T-shaped rods 11 are movably connected through each clamping seat 7, and the mounting plate 21 is provided at the opposite ends of the two T-shaped rods 11. Two symmetrical connecting plates 12 are fixedly connected to each T-shaped rod 11, and each connecting plate 12 is provided with an oblique groove 13. The two oblique grooves 13 of the same group are connected by a guide frame 14, and the guide frame 14 is fixedly connected to the end of the push plate 15. The push-type extrusion assembly also includes an axis connected to the push plate 15 toward the corresponding A connecting rod 17 on one side of the sliding frame 6, and a corresponding connecting tube 18 is sleeved on the outer side of the connecting rod 17. The connecting tube 18 is axially connected to the lateral strip plate of the corresponding clamping seat 7, and circular support plates are provided on the connecting tube 18 and the connecting rod 17, and a spring 19 for resetting is provided between the relative support plates. The structure composed of the connecting rod 17, the connecting tube 18 and the spring 19 is provided with two groups on the inner side of each C-shaped clamping seat 7, and the two groups of structures on the inner side of each clamping seat 7 are arranged in an eight-shaped shape. A push-pull frame 9 is slidably connected to the clamping seat 7, and a right-angled triangle block is provided on the push-pull frame 9. The position of the right-angled triangle block corresponds to the end position of the push plate 15 that passes through the outer side of the clamping seat 7, and the outer end of the worm 8 movably passes through the push-pull frame 9.

[0020] according to Figure 3-Figure 5 , the light metal alloy to be clamped is pushed between the two opposite mounting plates 21. During this process, the push plate 15 is squeezed, causing the push plate 15 to move. During the movement of the push plate 15, the spring 19 is first compressed and then released, so that after the push plate 15 moves to a certain extent, it only has the tendency to move toward the corresponding sliding frame 6; When the push plate 15 moves, it drives the guide frames 14 connected to its upper and lower ends to move synchronously, so that the guide frames 14 can slide in the corresponding inclined slots 13, so as to facilitate the two opposing T-shaped bars 11 to approach each other, thus achieving the purpose of approaching each other of the two mounting plates 21. By approaching each other, the two mounting plates 21 can be made to move toward each other, so that the opposing sliding rollers 24 can clamp the light metal alloy. Since the push plate 15 has a tendency to move toward the corresponding sliding frame 6 after moving to a certain extent, the opposing sliding rollers 24 can stably clamp the light metal alloy. In addition, after the light metal alloy is welded, the push-pull frame 9 can be pulled to squeeze the two ends of the push plate 15 using the right-angled triangle blocks provided thereon, so that the relative sliding rollers 24 move away from each other, thereby helping to loosen the light metal alloy after welding. The above operation process is convenient and quick, thereby helping to improve the efficiency of welding.

[0021] Example 2: In order to solve the problem that the previous welding tooling cannot straighten the light metal alloy, which easily causes the two light metal alloys to be welded to be misaligned, so that welding cannot be carried out smoothly, the following technical solution is provided. Specifically, an extrusion type positioning assembly is provided on the mounting plate 21, and the extrusion type positioning assembly includes a positioning roller 25 for positioning.

[0022] The extrusion type positioning assembly also includes a slide groove 22 arranged on the upper surface of the mounting plate 21, and a support plate 23 is slidably connected to the slide groove 22, and sliding rollers 24 are evenly arranged on the support plate 23, and both ends of the sliding rollers 24 are bearing-connected to the support plate 23. A magnetic block group 29 is also provided between the inner end of the slide groove 22 and the support plate 23. The magnetic block group 29 is composed of two magnetic blocks, and the two magnetic blocks are respectively arranged on the inner end of the slide groove 22 and the side of the support plate 23 facing the inner end of the slide groove 22, and the opposite sides of the two magnetic blocks are opposite magnetic poles. The extrusion type positioning assembly also includes a shaft rod 26 installed on the side of the mounting plate 21, and the shaft rod 26 is bearing-connected between the protrusions on the side of the mounting plate 21. Two lateral positioning frames 27 are symmetrically provided on each shaft rod 26, and the positioning roller 25 bearing sleeve is arranged on the outer side of the middle part of the lateral positioning frame 27. Connecting blocks 28 are fixedly connected to both sides of the support plate 23, and the connecting blocks 28 are threaded through by the corresponding shaft rod 26.

[0023] according to Figure 6-Figure 9 , rotate the screw 2 to make the two limit seats 4 approach each other, thereby achieving the docking of the two light metal alloys. During the docking process, the two light metal alloys are bound to squeeze each other, and then the support plate 23 can be moved in the slide groove 22 through friction (an anti-slip sleeve is provided on the outside of the sliding roller 24); During the above process, the connecting block 28 will move relative to the shaft 26. Since the two are connected by a twisted shaft thread, the purpose of driving the shaft 26 to rotate can be achieved. During the rotation of the shaft 26, the positioning roller 25 and the lateral positioning frame 27 are driven to rotate synchronously, so that the light metal alloy can be straightened by the positioning roller 25 to avoid misalignment of the two light metal alloys being docked, which is conducive to the smooth progress of the welding process.
