Description

Technical Field

[0001] The utility model relates to the technical field of laser welding machines, in particular to a laser welding machine with a heat dissipation mechanism. Background Art

[0002] Laser welding machines use high-energy laser pulses to locally heat a small area of ​​the material. The energy of the laser radiation diffuses into the interior of the material through heat conduction, melting the material to form a specific molten pool to achieve the purpose of welding. Existing laser welding machines are usually composed of a laser welding machine body, a welding gun and an optical fiber. In order to ensure the normal operation of the welding gun, the welding gun needs to be connected to the laser welding machine housing through an optical fiber, and the laser welding machine housing provides the required energy for the welding gun to enable it to be used normally.

[0003] The laser welding machine body is the main control unit, and there are many kinds of electronic components inside it. During operation, the components inside it generate a lot of heat, which needs to be dissipated. Otherwise, the internal electronic components will be damaged due to overheating, which will easily shorten the service life of the laser welding machine chassis and affect the efficiency of the laser welding machine. Most of the existing laser welding machines dissipate heat through the ventilation holes on the surface of the chassis, which has poor heat dissipation effect and low heat dissipation efficiency.

[0004] During use, the worker needs to hold the welding gun and move it according to the different positions of the welding points. However, if the welding area is large and the length of the welding gun connecting line is not enough, the worker needs to carry the welding machine body and move it. However, the welding machine body has a certain weight, which will increase the labor intensity of the worker, make it inconvenient for the worker to carry and move it, and reduce work efficiency.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a laser welding machine with a heat dissipation mechanism, comprising a welding machine body and a liquid storage tank fixed to one side of the top of the welding machine body, and further comprising: a small water pump connected to one side of the liquid storage tank, the water outlet of the small water pump being connected to a liquid infusion tube, a cooling mechanism being provided on one side of the welding machine body, a ventilation shell being fixedly connected to the other side of the welding machine body, an exhaust fan being installed inside the ventilation shell, and mounting brackets being fixedly connected to the middle of both sides of the welding machine body;

[0007] The positioning plates are fixed on both sides of the top of the inner wall of the mounting frame, and a movable groove is opened on the inner side of the positioning plate. An electric telescopic rod is installed in the middle of the top of the inner wall of the mounting frame, and the bottom of the output shaft of the electric telescopic rod is fixedly connected to a fixed plate. An adjustment mechanism is provided on one side of the positioning plate, and a movable wheel is installed at the bottom of the adjustment mechanism.

[0008] Preferably, the cooling mechanism includes a mounting shell fixed to one side of the welding machine body and a servo motor mounted on one side of its ventilation window, and also includes a rotating fan blade fixed to one side of the servo motor output shaft and a diverter plate fixed at the inner opening of the mounting shell.

[0009] Preferably, the adjustment mechanism includes a fixing rod fixed below one side of the positioning plate and a connecting rod rotating on one side thereof, and also includes a hinged rod rotating above one side of the connecting rod and fixing blocks fixed on both sides below one side of the fixing plate.

[0010] Preferably, the infusion tube is serpentine in shape and is arranged on one side of the welding machine body.

[0012] Preferably, a plurality of ventilation holes are provided on the surface of the diverter plate, and the ventilation holes are arranged on one side of the infusion tube.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model uses a small water pump and an infusion tube to extract the coolant inside the liquid storage tank for circulation and transportation to cool the welding machine body. At the same time, the cooling mechanism and the exhaust fan cooperate to extract the hot air inside the welding machine body and then input cold air for air circulation, thereby improving the heat dissipation efficiency and further improving the heat dissipation effect of the welding machine body. When the welding machine body needs to be moved, the electric telescopic rod controls the lifting and lowering of the fixed plate while the adjustment mechanism drives the moving wheels to expand outward. The moving wheels can push the welding machine body when in contact with the ground, which makes it convenient for the staff to move the position of the welding machine body. This solves the problem that the current laser welding machine has poor heat dissipation effect and is inconvenient to move when in use. BRIEF DESCRIPTION OF THE DRAWINGS

In use, the heat dissipation effect of the welding machine body 1 is improved. The middle of both sides of the welding machine body 1 is fixedly connected with a mounting frame 8. The shape of the mounting frame 8 is U-shaped, and the mounting frames 8 on both sides of the welding machine body 1 are symmetrical with each other. The mounting frame 8 is used to install the bottom parts. At the same time, the welding machine body 1 can be supported during work. Both sides of the top of the inner wall of the mounting frame 8 are fixedly connected with a positioning plate 9. The positioning plate 9 is used to position the parts. A moving groove 10 is provided on the inner side of the positioning plate 9. The moving groove 10 is used to guide the parts on one side. An electric telescopic rod 11 is installed in the middle of the top of the inner wall of the mounting frame 8.

[0022] The cooling mechanism 5 includes a mounting shell 51 fixed to one side of the welding machine body 1. The mounting shell 51 is arranged on the outside of the infusion tube 4. A servo motor 52 is installed on one side of the ventilation window of the mounting shell 51.
