Description

Technical Field

[0001] This utility model relates to the field of laser welding machine welding torch equipment, and in particular to a laser welding machine welding torch with rapid heat dissipation. Background Technology

[0002] Laser welding utilizes high-energy laser pulses to locally heat a small area of ​​material. The energy from the laser radiation diffuses into the material through heat conduction, melting the material and forming a specific molten pool. It is a novel welding method, primarily used for welding thin-walled materials and precision parts.

[0003] A search revealed Chinese Patent Publication No. CN218341286U, which discloses a welding torch airflow cooling mechanism for a handheld laser welding machine. This mechanism relates to the field of welding torch cooling and includes a welding torch body. The welding torch body comprises a handle, a barrel, and a handle. The barrel is connected to one side of the laser emitting part of the barrel, and the handle is connected to one side of the laser receiving part. The welding torch body has an internal cooling mechanism for cooling the laser receiving part. This cooling mechanism includes a cooling pipe, which consists of an inlet pipe, a heat-conducting pipe, and an outlet pipe. The cooling pipe replaces the traditional air pipe. During use, a protective gas suitable for welding the workpiece is introduced into the inlet pipe. The spiral heat-conducting pipe, with its large heating area, quickly removes heat from the laser receiving part of the welding torch. The gas, having absorbed heat, is discharged from the outlet pipe to the barrel and then sprayed onto the surface of the welding material. This achieves both cooling of the laser receiving part and protection of the weld joint.

[0004] The above-mentioned device has the following defects: the welding torch head generates high temperature when it comes into contact with the surface of the workpiece under the action of laser. This causes the temperature of the welded part to rise sharply after welding due to the high temperature of the laser welding torch head, resulting in insufficient heat dissipation and the phenomenon of incomplete welding. Therefore, a laser welding torch with rapid heat dissipation is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a laser welding torch with rapid heat dissipation, which aims to improve the problem of insufficient heat dissipation in the welding part and resulting in incomplete welding in the prior art.

[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] Reference Figure 1 - Figure 2The present invention provides an embodiment of a laser welding torch with rapid heat dissipation, comprising a welding torch 5, which supports the equipment. A fixing frame 4 is fixedly installed on the right side of the front surface of the welding torch 5, which fixes the handle 1. The handle 1 is fixedly connected to the lower surface of the fixing frame 4. A welding head 6 is fixedly installed on the left end of the welding torch 5, which is used for welding the object. Two sets of heat dissipation components 2 are provided on the left ends of both the front and rear surfaces of the welding torch 5. An auxiliary component 3 is provided on the lower surface of the left end of the welding torch 5.

[0025] Reference Figure 1 - Figure 3 When the welding gun 5 needs to weld the object for a long time, the heat dissipation assembly 2 is activated. The heat dissipation assembly 2 includes a mounting plate 22. The left end of the front and rear surfaces of the welding gun 5 is provided with a mounting groove 21. The operator pulls the mounting plate 22 out of the mounting groove 21 using the handle of the mounting plate 22. A circular groove is provided at the axis of the mounting groove 21. Two sets of mounting seats 23 are fixedly connected to the upper and lower two sets of the left end of the inner wall of the mounting groove 21. The mounting seats 23 cooperate with the mounting plate 22 to unfold the mounting plate 22 after it is pulled out. The mounting plate 22 is fixedly connected to the left end of the inner wall of the mounting groove 21 through the mounting seats 23. The motor 27 is started. The output shaft of the motor 27 rotates and drives the fan blade 26 to rotate. The right surface of the mounting plate 22 is fixedly connected to the axis of the motor 27. The output shaft of the motor 27 is fixedly connected to the fan blade 26, so that the airflow is on the fan blade. The rotation of blade 26 dissipates heat from the welded parts of the workpiece, preventing incomplete welds caused by high surface temperatures during welding. This accelerates the formation of welds on the workpiece surface, improves heat dissipation of the welded parts, and enhances the welding effect. Magnetic blocks 25 are fixedly connected to the upper and lower sides of the front right side of the mounting plate 22. After welding with the welding gun 5, the mounting plate 22 is reset into the mounting groove 21 via the mounting base 23. Two sets of magnetic grooves 24 are provided on the upper and lower sides of the right end of the inner wall of the mounting groove 21. The magnetic blocks 25, in conjunction with the magnetic grooves 24, limit the position of the reset mounting plate 22. The cross-sectional area of ​​the magnetic groove 24 matches the cross-sectional area of ​​the magnetic block 25. The outer wall of the magnetic block 25 is magnetically connected to the inner wall groove of the magnetic groove 24, reducing the area occupied by the welding gun 5 during storage and improving the ease of use of the heat dissipation component 2.

[0026] Reference Figure 2 - Figure 4When alignment of the welding area is required, auxiliary component 3 is activated. Auxiliary component 3 includes auxiliary seat 31, which is fixedly connected to the lower surface of the left end of welding gun 5. An adjusting rod 34 is hinged to the inner wall of auxiliary seat 31 through rotating column 35. The operator rotates the adjusting rod 34 by rotating column 35, so that the visible light emitted by auxiliary laser pointer 33 is aligned with the position of welding head 6. A fixing nut 32 is threaded at the front thread of rotating column 35, which positions the calibrated adjusting rod 34. Auxiliary laser pointer 33 is fixedly installed on the lower surface of adjusting rod 34. Rotating column 35 is connected through the groove on the front surface of auxiliary seat 31. The visible light emitted by auxiliary laser pointer 33 assists in calibrating the welding path of welding head 6 during the welding process, improving the accuracy of using welding gun 5 and enhancing the welding effect of the equipment.

[0027] Working Principle: When welding gun 5 needs to weld on an object for an extended period, the heat dissipation assembly 2 is activated. The operator pulls the mounting plate 22 out of the mounting slot 21 using the handle. The mounting base 23, in conjunction with the mounting plate 22, unfolds the plate. Motor 27 is then activated, and its output shaft rotates, driving the fan blades 26 to rotate. This airflow, driven by the rotating fan blades 26, dissipates heat from the welded portion of the workpiece, preventing incomplete welds caused by high surface temperatures during welding. This accelerates the formation of welds on the workpiece surface, improves heat dissipation in the welded portion, and enhances the welding effect. After welding gun 5 completes welding, the heat dissipation is achieved through the mounting base 23. The mounting plate 22 is reset into the mounting slot 21. The magnetic block 25, in conjunction with the magnetic slot 24, limits the position of the reset mounting plate 22, reducing the area occupied by the welding gun 5 and improving the ease of use of the heat dissipation component 2. When the welding area needs to be aligned, the auxiliary component 3 is activated. The operator rotates the adjusting rod 34 by rotating the column 35, aligning the visible light emitted by the auxiliary laser pointer 33 with the position of the welding head 6. The adjusting rod 34 is positioned by fixing the nut 32. The visible light emitted by the auxiliary laser pointer 33 assists in calibrating the welding path of the welding head 6 during the welding process, improving the accuracy of using the welding gun 5 and enhancing the welding effect of the equipment.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
