Technical Field

[0001] The utility model relates to the technical field of laser welding, and specifically relates to a movable fixture during the laser welding process. Background Art

[0002] A laser welding machine refers to a machine used for laser material processing, also known as a laser welding machine or a laser welder. It can often be classified into a laser die welding machine, an automatic laser welding machine, a laser spot welder, and a fiber transmission laser welding machine according to its working mode.

[0003] The existing double transparent welding machine only supports the quasi-synchronous welding process. Due to being restricted by the scope of the galvanometer scanner, it can only weld an area of 90*90m at a time. When welding products with a larger area, the splicing method needs to be used for welding, which will leave splicing marks, resulting in the risk of liquid leakage, and it is also necessary to turn the fixture during welding, leading to the problem of low welding efficiency.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a movable fixture during the laser welding process is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide a movable fixture during the laser welding process to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A movable fixture during the laser welding process includes a bottom plate and a clamping assembly. A driving electric cylinder is arranged at one end of the bottom plate, and a moving seat is arranged at the end of the driving electric cylinder. The clamping assembly is arranged on the top of the moving seat. The clamping assembly includes a cylinder, a glass frame, and a glass cover. Cylinders are symmetrically arranged at both ends of the top of the moving seat, and a glass frame is connected to the top of the cylinder. A glass cover is fixed in the middle of the glass frame. The number of cylinders is four, and the four cylinders are symmetrically arranged about the center line of the glass frame.

[0007] Further, sliders are arranged at both ends of the bottom of the moving seat, and the bottom of the slider is slidably connected to a guide rail, and the guide rail is fixed to the bottom plate.

[0008] Further, limiting blocks are symmetrically arranged on both sides of the bottom plate, and buffer rods are fixed inside the upper ends of the limiting blocks.

[0009] Further, baffles are symmetrically arranged at both ends of the bottom of the moving seat, and the baffles correspond to the buffer rods one by one.

[0010] Further, a guide rod is fixed in the middle of the top of the moving seat, and a linear bearing is sleeved on the outer side of the upper end of the guide rod.

[0011] Furthermore, the glass rack is rectangular and fixedly connected to the linear bearing.

[0012] Furthermore, a glass clearance block is provided below the glass cover, and a product upper cover is provided at the bottom of the glass clearance block.

[0013] Furthermore, the bottom of the product upper cover is connected to a product lower shell, and a positioning jig is provided at the bottom of the product lower shell.

[0014] The present utility model provides a movable fixture during laser welding, having the following beneficial effects:

[0015] 1. Through the setting of the clamping assembly in the present utility model, the air cylinder can drive the glass rack to move downward, and the glass cover will press and position the product on the positioning jig, so as to perform quasi-synchronous welding or contour welding operations on the product. And when the product is too large, after welding this part of the product is completed, the glass cover can be moved upward by the air cylinder, and then the driving electric cylinder is used to drive the moving seat to move, so that the position during clamping can be changed, so as to press and position the other section of the workpiece. At this time, the welding head will move synchronously to this section of the product, so this section of the product can be welded, and there is no need to change the fixture direction after welding half of it and adjust the machine again, thus improving the welding efficiency and greatly expanding the compatibility of the welded products. Especially when welding large-size products, it has great advantages;

[0016] 2. Through the setting of the guide rod and the linear bearing in the present utility model, the stability of the vertical movement of the glass rack can be improved, and at the same time, the slider and the guide rail can be used to enhance the stability of the horizontal movement of the moving seat, avoiding the situation of offset and skew of the fixture during use. And when the moving seat moves to both ends of the bottom plate, the baffle will contact the buffer rod, thus playing a buffer and protection effect and avoiding rigid collision and aggravating damage.

A driving electric cylinder 2 is arranged at one end of the bottom plate 1, and a moving seat 3 is arranged at the end of the driving electric cylinder 2. When the product is too large, after welding a section of the product, the driving electric cylinder 2 drives the moving seat 3 to move, so as to change the clamping position, so as to press and position another section of the workpiece. At this time, the welding head will move synchronously to this section of the product, so that this section of the product can be welded. The clamping assembly 4 is arranged on the top of the moving seat 3. The clamping assembly 4 includes a cylinder 401, a glass frame 402 and a glass cover 403. Cylinders 401 are symmetrically arranged at both ends of the top of the moving seat 3, and a glass frame 402 is connected to the top of the cylinder 401, and a glass cover 403 is fixed in the middle of the glass frame 402. The number of cylinders 401 is four, and the cylinders 401 are symmetrically arranged about the center line of the glass frame 402. The cylinder 401 can drive the glass frame 402 to move down, and the glass cover 403 will press and position the product on the positioning fixture 15. Sliders 5 are arranged at both ends of the bottom of the moving seat 3, and the bottom of the slider 5 is slidably connected to a guide rail 6, and the guide rail 6 is fixed to the bottom plate 1. The sliders 5 and the guide rail 6 are used to enhance the stability of the horizontal movement of the moving seat 3 and avoid the situation of offset and skew of the fixture during use.

[0023] As Figures 1 to 3As shown, limit blocks 7 are symmetrically arranged on both sides of the bottom plate 1, and buffer rods 8 are fixed inside the upper ends of the limit blocks 7. Baffles 9 are symmetrically arranged at both ends of the bottom of the moving seat 3, and the baffles 9 correspond to the buffer rods 8 one by one. When the moving seat 3 moves to both ends of the bottom plate 1, the baffle 9 will contact the buffer rod 8, thus playing a role of buffering and protection to avoid rigid collision and aggravating damage. A guide rod 10 is fixed in the center of the top of the moving seat 3, and a linear bearing 11 is sleeved on the outer side of the upper end of the guide rod 10. The glass frame 402 is rectangular, and the glass frame 402 is fixedly connected with the linear bearing 11. The stability of the vertical movement of the glass frame 402 can be improved through the guide rod 10 and the linear bearing 11. A glass clearance block 12 is arranged below the glass cover 403, and a product upper cover 13 is arranged at the bottom of the glass clearance block 12. The bottom of the product upper cover 13 is connected with a product lower shell 14, and a positioning fixture 15 is arranged at the bottom of the product lower shell 14. The positioning fixture 15 is used to position the product lower shell 14 and the product upper cover 13.

[0024] In summary, during the use of the movable fixture in the laser welding process, first, according to Figure 1 、 Figure 2 and Figure 3 the structures shown in, first fix the positioning fixture 15 on the laser welding machine, and start the driving electric cylinder 2 to make the glass frame 402 move to the welding starting position. Secondly, fix the product lower shell 14 and the product upper cover 13 on the positioning fixture 15, and fix the glass clearance block 12 on the product upper cover 13. Then, the cylinder 401 drives the glass frame 402 to move down, and the glass cover 403 will press and position the product on the positioning fixture 15 to perform quasi-synchronous welding or contour welding operations on the product. During this process, the stability of the vertical movement of the glass frame 402 is improved by using the guide rod 10 and the linear bearing 11. Then, after welding this part of the product is completed, the glass cover 403 can be lifted by the cylinder 401, and the moving seat 3 can be driven to move by the driving electric cylinder 2. At this time, the slider 5 and the guide rail 6 are used to enhance the stability of the horizontal movement of the moving seat 3, and the clamping position can be changed to press and position the other section of the workpiece. At this time, the welding head will move synchronously to this section of the product, so this section of the product can be welded. Finally, after welding is completed, the cylinder 401 drives the glass frame 402 to move up to open the fixture, so as to take out the product for blanking.
