Description

Technical Field

[0001] The utility model relates to the field of welding equipment, in particular to an intelligent laser welding cooling mechanism. Background Art

[0002] Laser welding refers to an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding has the advantages of fast speed, large depth, small deformation, high weld quality, and high degree of automation. Laser welding is commonly used in automobile manufacturing, electronics and electrical industry, medical industry, hardware industry, aerospace and other fields. Heat is generated during the laser welding process and needs to be cooled to avoid excessive temperature affecting the welded material. The existing cooling method is to use a circulating liquid to cool the welding material, and the cooling effect is average. Therefore, it is particularly necessary to develop an intelligent laser welding cooling mechanism with better cooling effect. Summary of the Invention

[0003] The purpose of the utility model is to provide an intelligent laser welding cooling mechanism, which has the advantage of better cooling effect.

[0004] The technical solutions adopted are as follows:

[0005] An intelligent laser welding cooling mechanism includes a shell, a groove is provided at the bottom end of the shell, a channel is vertically opened at the upper end of the shell and passes through the groove, a plurality of air outlet ducts extending to the outside of the shell are opened on the outside of the groove, a mounting ring is rotatably provided in the groove, an outer gear ring is provided on the outside of the mounting ring, a driving motor is provided on the shell, the driving motor is provided with a driving gear engaged with the outer gear ring, a plurality of fan blades are provided on the inner side of the mounting ring, a cavity is provided in the shell, a liquid inlet pipe and a liquid outlet pipe are provided in the cavity, a plurality of air outlets are provided in the channel, the shell is provided with a gas pipe connected to the air outlet, and the gas pipe is connected to a protective gas tank.

[0006] Preferably, the air outlets are all inclined downward and extend toward the center of the channel.

[0007] Preferably, a plurality of ventilation slots are provided on the mounting ring.

[0008] Preferably, the mounting ring is made of mesh.

[0009] Preferably, the driving motor is a variable frequency motor.

[0010] Compared with the existing technology, the beneficial effects are:

[0011] The utility model utilizes a liquid inlet pipe to inject coolant into the cavity, and the coolant cools the shell. The lower end of the shell contacts the material to be welded, thereby cooling the material to be welded. At the same time, the gas pipe inputs the protective gas from the input pipe into the channel. When the fan blades rotate, the gas in the channel is drawn into the groove and discharged from each air outlet. In this process, a part of the heat generated by the welding process is taken away. Compared with the traditional cooling method using only water, the cooling effect is better. BRIEF DESCRIPTION OF THE DRAWINGS
