[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Among them, laser welding technology belongs to fusion welding, which uses laser beam as energy to impact the weld joint to achieve the purpose of welding. It consists of an optical oscillator and a medium placed between the mirrors at both ends of the oscillator cavity.

[0003] Laser welding technology is of great significance to automation, especially in improving production efficiency, ensuring welding quality, and promoting intelligent and automated production. In order to optimize the welding efficiency of large parts, some multi-point automatic welding equipment has been launched on the market. However, the integration of this type of welding equipment is not high, and the floor space is large. If the number of workpieces to be processed is small, the use of this equipment will bring about a large cost expenditure. Summary of the invention

[0004] The invention discloses a one-to-four welding device, aiming to solve the technical problems that multi-spot welding devices have low integration and occupy a large area, and if the number of workpieces to be processed is small, using the device will bring about a large cost expenditure.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A one-to-four welding device comprises a hood, wherein side sealing doors are respectively arranged on opposite sides of the hood, and a visual window is inlaid on one inner wall of the hood, a cooling mechanism is arranged on the top of the hood, and a plurality of legs are fixedly connected to the bottom end of the hood, a smoking port is penetrated through the bottom end of the hood, a clamping mechanism is connected to the inner wall of one side of the cooling mechanism, and a plurality of cross frames are fixedly connected to the inner wall on the same side of the cooling mechanism, a bracket is fixedly connected to the outer walls on the same side of the plurality of cross frames at the same time, and a plurality of fixing holes are arranged on the bracket, and four welding mechanisms are fixedly connected to the bracket through the plurality of fixing holes;

The laser welding gun and the sensor are connected, and both are fixed on the swing support at the same time.

[0008] Multiple welding mechanisms are integrated through the machine hood. When the workpiece is clamped by the clamping mechanism, the workpiece can be fixed in the middle position inside the machine hood, and the welding surface can correspond to multiple welding mechanisms. The installation position and combination form of the welding mechanism can be changed through multiple fixed holes, so that it can adapt to the use of different workpieces to find a better joint welding position. In the welding mechanism, the laser welding gun is driven to move by adjusting the support and the swing support. When the workpiece is fixed, it can be automatically welded on the workpiece surface along the weld bead. Under this structure, the welding efficiency of a single welded part can be optimized. At the same time, the welding position can be quickly located by multi-point synchronous welding, which also plays a role in avoiding welding dislocation.

[0009] In a preferred embodiment, the clamping mechanism includes a longitudinal guide rail, and the longitudinal guide rail is fixed to an inner wall of one side of the hood, a slide is movably connected to the longitudinal guide rail, and an outer wall of one side of the slide is fixedly connected to a support seat, an arc-shaped through-groove is provided on one side of the support seat, and a bidirectional screw drive group is movably connected to the inner wall of the arc-shaped through-groove, an outer wall of one side of the bidirectional screw drive group is attached to the outer wall of the arc-shaped through-groove, and the bidirectional screw drive group is connected to a second gear through the arc-shaped through-groove, the second gear is located in the support seat, and both sides of the second gear They are respectively connected to the inner wall of the support seat through the second support shaft, one side of the second gear is meshed with the first gear, and one side of the first gear is connected to the servo motor through the first support shaft, the first support shaft passes through the support seat, and the servo motor is fixed to one side of the outer wall of the support seat, two clamps are symmetrically connected to the bidirectional screw drive group, the top outer wall of the bidirectional screw drive group is fixedly connected to the limiting frame, and an L-shaped limiting frame is movably connected in the limiting frame, one side of the limiting frame is meshed with a screw, and one end of the screw is against one side of the L-shaped limiting frame.

[0010] By providing a clamping mechanism, the clamping mechanism mainly drives the clamping plate to clamp the two sides of the workpiece through the bidirectional screw drive group, wherein the clamping structure can be driven through the feed port under the action of the longitudinal guide rail to complete the installation of the workpiece outside the machine cover, thereby reducing the difficulty of installation; at the same time, under the guidance of the arc-shaped through groove, when the servo motor drives the first gear to rotate, based on the linkage structure of the second gear, the placement angle of the main clamping structure can be changed in the machine cover, so that the welding surface of the workpiece can be parallel to multiple welding mechanisms, which is more convenient for multi-point positioning welding and can also be adapted to the use of workpieces of different shapes.
