Description

Technical Field

[0001] This utility model relates to the field of laser welding technology, specifically a steel plate clamping device. Background Technology

[0002] Laser welding is a welding technology that uses a high-energy laser beam as a heat source to melt and join two metals or other materials. Laser welding is characterized by high efficiency, high precision, and high quality, and is therefore widely used in precision manufacturing, electronics, aerospace, automotive, and other fields.

[0003] During the processing of a real fireplace enclosure, steel plates need to be welded. In order to ensure welding quality, improve weld strength and reduce defects, the steel plate workpieces need to be tightly joined together during welding. Existing laser welding mostly uses top extrusion for fixation, which cannot be done by lateral movement after the workpiece is fixed. There are gaps between the steel plate workpieces, and the laser beam will cause the gas in the molten pool to not be effectively discharged, thus forming pores and other welding defects. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this utility model provides a technical solution: a steel plate clamping device, comprising: a support platform 1; a fixed clamping part disposed at one end of the support platform 1, the fixed clamping part including a fixed clamping plate 2 and a fixed clamping plate 5 fixedly installed at the top and bottom, the width of the fixed clamping plate 2 being greater than the width of the fixed clamping plate 5, the fixed clamping plate 2 being fixedly connected to the support platform 1, the fixed clamping plate 2 being flush with the height of the movable clamping plate 8, a side baffle 3 being fixedly connected to one side of the fixed clamping plate 2, and a side clamp for clamping and fixing being provided between the fixed clamping plate 2 and the side baffle 3. The holding plate 4 is used to vertically clamp the steel plate; the movable clamping part is slidably placed on one side of the side baffle 3. The movable clamping part includes a movable clamping plate 2 9 and a movable clamping plate 1 8 fixedly arranged at the top and bottom. The movable clamping plate 1 slidably connects to the support platform 1. Pads are installed between the end of the fixed clamping plate 1 2 and the end of the fixed clamping plate 2 5, and between the end of the movable clamping plate 1 8 and the end of the movable clamping plate 2 9, to form an installation clamping space. A cylinder 3 12 is fixedly connected to one side of the movable clamping plate 1 8 to drive the movable clamping plate 1 8 to move towards the fixed clamping plate 1 2 to achieve steel plate docking.

[0025] It should be noted that in this embodiment, the steel plates to be welded are placed between the fixed clamping plate 1 2 and the fixed clamping plate 2 5, and between the movable clamping plate 1 8 and the movable clamping plate 2 9, so that the edge of one of the steel plates is located near the edge of the fixed clamping plate 1 2 near the side baffle 3, and the edge of the other steel plate is aligned with the edge of the side baffle 3 near the movable clamping plate 1 8. The foot switch controls the cylinder 1 6 to drive the lifting clamping block 10 downward to clamp and fix the steel plates. Then, the cylinder 3 12 drives the cylinder 2 7 to move to one side of the fixed clamping plate 1 2, thereby connecting the two steel plates together so that the connection point corresponds to the laser welding machine. The laser welding machine moves along the connection gap to achieve welding.

[0026] In one embodiment, such as Figure 1 , 3 As shown in Figure 4, it also includes a vertical plate 13 fixed to the bottom of the support platform 1. A support plate 14 is slidably connected to one side of the vertical plate 13. A fastening bolt 16 is threaded to one end of the support plate 14 to fix the support plate 14 to one side of the vertical plate 13. A lead screw 15 is rotatably connected to the middle of the vertical plate 13. The lead screw 15 is threaded to the support plate 14. A handwheel for driving the lead screw 15 is fixed to the bottom of the lead screw 15.

[0027] It should be noted that when welding the counter is required in this embodiment, the height of the support plate 14 is adjusted by the lead screw 15 so that the support plate 14 supports the counter from the bottom. After the height of the support plate 14 is adjusted, the support plate 14 is tightly fixed to the vertical plate 13 by tightening the fastening bolts 16 to prevent displacement during use. The box frame is placed on top of the fixed clamping plate 2 and the movable clamping plate 8, and its lower side is placed on top of the support plate 14. The box is clamped and fixed by the cylinder 6. The movable clamping plate 8 is driven by the cylinder 12 to connect the interface and welded by the laser welding machine.

[0028] In one embodiment, such as Figure 1 , 2 As shown in Figures 3, 4, and 6, cylinder 6 is fixedly connected to the top of both the fixed clamping plate 2 5 and the movable clamping plate 2 9, and lifting clamping block 10 is fixedly connected to the output end of cylinder 6.

[0029] It should be noted that in this embodiment, the steel plate is placed between the fixed clamping plate 12 and the fixed clamping plate 25 and between the movable clamping plate 18 and the movable clamping plate 29. The lifting clamping block 10 is driven to move downward by the cylinder 16, thereby pressing and fixing the steel plate below through the lifting clamping block 10.

[0030] In one embodiment, such as Figure 2 , 4 As shown in Figure 5, a cylinder 7 is fixedly connected to the outer side of the fixed clamping plate 2, and the output end of the cylinder 7 is fixedly connected to the side clamping plate 4.

[0031] It should be noted that, in this embodiment, when welding the right angle of the box body, the vertical edge is placed between the side clamping plate 4 and the side baffle 3. The bottom of the vertical edge is supported by adjusting the height of the support plate 14. The horizontal plane is placed between the moving clamping plate 1 8 and the moving clamping plate 2 9. The cylinder 2 7 drives the side clamping plate 4 to clamp and press the vertical plate between the side baffle 3 and the side clamping plate 4. The cylinder 1 6 drives the lifting clamping block 10 to clamp and fix the horizontal plane on the top of the moving clamping plate 1 8. The cylinder 3 12 also drives the moving clamping plate 1 8 to move to one side to connect the vertical plate and the horizontal plate.

[0032] In one embodiment, such as Figure 2 , 3 As shown, two limiting rods 11 are fixedly connected to one side of the side baffle 3. The limiting rods 11 are slidably connected to the movable clamping plate 8. The cylinder 12 is located between the two limiting rods 11 and the output end of the cylinder 12 is fixedly connected to the side baffle 3. A T-shaped limiting groove 17 is provided on one side of the movable clamping plate 8. A slider that cooperates with the limiting groove 17 is fixedly connected to the end of the support platform 1.

[0033] It should be noted that when the piston rod of cylinder 12 retracts in this embodiment, under the action of the pulling force, the moving clamp 8 moves downward along the limiting rod 11 toward the side baffle 3. At the same time, the limiting groove 17 at one end of the moving clamp 8 slides at the end of the support platform 1, thereby realizing that the moving clamp 8 drives the clamped steel plate to move and dock to one side.
