Description

Technical Field

[0001] This utility model relates to the field of welding fixture devices, and in particular to a laser welding device including a laser welding fixture. Background Technology

[0002] Laser welding is a processing method that uses a laser beam to weld workpieces. Laser welding uses a high-energy-density laser beam to heat the surface of the workpiece to above the melting point, causing the workpiece surface to melt and form a weld in the molten pool. Laser welding has the characteristics of high precision and high speed, and is widely used in industries such as automobiles, aerospace, electronics, medical devices, and shipbuilding.

[0003] During the production process, due to the inherent dangers of welding, workpieces cannot be directly fixed by hand. Therefore, laser welding fixtures are required. A laser welding fixture is a device used to fix workpieces and maintain their stable position, ensuring that the workpieces can maintain consistent precision and quality during processing. It plays a very important role in the laser welding process.

[0004] Currently, most laser welding fixtures are fastening fixtures, which use manual, electric, or pneumatic drives to clamp the workpiece between two clamping blocks for welding. However, in actual use, many thin-walled workpieces need to be welded, such as thin-walled round tubes. Traditional fixtures fix the workpiece by squeezing, and if the pressure is too low, the clamping will be unstable, causing displacement during welding. If the pressure is too high, the thin-walled round tube will deform. Therefore, clamping thin-walled workpieces is very inconvenient, easily leading to material waste and reduced work efficiency. Furthermore, after welding, the workpiece cannot be air-cooled in time, resulting in problems such as porosity and cracks at the weld, which reduces production quality.

[0005] Therefore, it is necessary to propose a laser welding device that includes a laser welding fixture to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a laser welding device including a laser welding fixture, so as to solve the problems mentioned in the background art that traditional clamping devices are very inconvenient to clamp thin-walled workpieces, are prone to unstable clamping or deformation causing material waste, and cannot be air-cooled in time after welding, resulting in porosity and cracks at the weld.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a laser welding device including a laser welding fixture, comprising an operating table, wherein a second base is mounted on the upper surface of the operating table near one side, a second vertical plate is mounted on the upper surface of the second base near one side, and a fixed cylinder is mounted on the other side surface of the second vertical plate.

[0008] The fixed cylinder has four slots evenly distributed on it. A fixed rod is fixedly installed on the fixed cylinder. The fixed rod is inclined and there are four fixed rods distributed corresponding to the slots. Horizontal through grooves are opened on the front and rear surfaces of the fixed rod, and vertical through grooves are opened on the side surfaces of the fixed rod.

[0009] A cylinder push rod is installed inside the fixed cylinder. Fixed push-pull components are installed on the cylinder push rod.

[0017] Preferably, a first movable block is installed on the lower surface of the first base, a second movable block is installed on the lower surface of the second base, and the bidirectional lead screw passes through the first movable block and the second movable block.

[0018] Preferably, a control switch is installed on the front surface of the control panel, and a back panel is installed on the rear surface of the control panel, with an air outlet on the back panel.

It solves the problem that when traditional clamps hold thin-walled cylindrical tubes, if the pressure is too small, the clamping will be unstable and displacement will occur during welding. If the pressure is too large, the thin-walled cylindrical tube will be deformed. It effectively avoids material waste caused by clamping and saves production costs.

For example, by replacing them with right-angle fasteners, thin-walled square tubes can be clamped, increasing the applicability of the device. Attached Figure Description

[0036] The movable rod 33 passes through the vertical through slot 29.

[0037] An exhaust hole 40 is provided at the other end of the fixed cylinder 10.

[0038] Furthermore, a fixed base 12 is fixedly installed on the upper surface of the second base 7 near the other side. A support rod 11 is fixedly installed on the upper surface of the fixed base 12. There are two support rods 11, and a fixed cylinder 10 is installed on the upper surface of the support rod 11.

[0039] Furthermore, a cylinder 8 is installed on one side surface of the second vertical plate 9. The output end of the cylinder 8 is connected to the cylinder push rod 42, which passes through the second vertical plate 9.

[0040] Furthermore, a base 2 is installed on the upper surface of the operating table 1 near the other side. A vertical plate 3 is installed on the upper surface of the base 2. A lead screw motor 4 is installed on the upper surface of the vertical plate 3. A lead screw groove 16 is opened on one side surface of the vertical plate 3.

During the movement, the fixed push-pull part 32 on the cylinder push rod 42 drives the movable rod 33 to move. During the movement, the movable rod 33 is limited by the sliding cylinder 36 and guided by the fixed rod 28, which will drive the fastener 31 to move vertically, thereby fixing the inner wall of the thin-walled round tube. The thrust released by the fastener 31 can not only fix the thin-walled round tube, but also make the device suitable for thin-walled round tubes of different diameters by moving the movable rod 33 in the vertical through groove 29, thus increasing the applicability of the device.

[0048] Considering that thin-walled workpieces include not only thin-walled round tubes but also thin-walled square tubes, a connecting post 41 and a mating part 39 are provided. The connecting post 41 and the mating part 39 are connected by a thread 38, which allows for the replacement of the fastener 31. For example, a right-angle fastener can be replaced to clamp the thin-walled square tube, increasing the applicability of the device. During use, the electromagnet 5 can be used to attract and fix the plate-shaped workpiece. Then, the second lead screw motor 20 is started, which drives the bidirectional lead screw 19 to move, causing the first base 2 and the second base 7 to move towards each other. After adjusting to the appropriate position, the plate-shaped workpiece and the thin-walled workpiece can be welded by a handheld laser welding machine. This solves the problem that traditional clamps cause unstable clamping when applying too little pressure and deformation of the thin-walled round tube when applying too much pressure, effectively avoiding material waste caused by clamping.
