Description

Technical Field

[0001] This utility model relates to the field of electric welding machine technology, and in particular to a handheld electric welding machine with a cooling structure. Background Technology

[0002] Electric welding machines utilize the high-temperature electric arc generated when the positive and negative electrodes are short-circuited momentarily to melt the welding material on the welding rod and the material being welded, thus joining the objects together. Handheld electric welding machines are portable welding devices that use electric current or lasers to generate high temperatures to melt metal and achieve connections. They are widely used in industrial manufacturing, home repair, and other fields.

[0003] Chinese Patent Publication No. CN218253330U discloses a handheld welding machine, including a welding machine body with a welding head and a control switch. This handheld welding machine, through a horizontal adjustment mechanism, allows the left hand to rotate a first knob to rotate a first screw, moving a first movable block back and forth, which in turn moves a connecting rod and a first slider back and forth, adjusting the upper and lower clamping plates to suitable positions. Then, a second screw and an insert rod are passed through corresponding threaded holes. Rotating a second knob rotates the second screw, moving the insert rod to insert into a slot on the second slider. Rotating a third knob rotates the third screw, moving the lower clamping plate up and down, adjusting the distance between the upper and lower clamping plates, and clamping the arm. This achieves stability by supporting the welding machine body with the arm, preventing damage if the hand accidentally releases the handle.

[0004] However, when using the aforementioned handheld welding machine, because the welding machine is in direct contact with the welding rod and the distance between the user's line of sight and the welding rod is short, when the welding rod is used for spot welding on the workpiece to be welded, the strong light emitted by the spot welding requires the user to wear reflective glasses or a protective mask. Wearing reflective glasses will reduce the user's vision, increase the operator's workload, and thus reduce the effectiveness of use. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a handheld welding machine with a cooling structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a handheld welding machine with a cooling structure, comprising a welding machine body, an installation component at the bottom of the welding machine body, fixed sleeve plates fixedly connected to both sides of the outer side wall of the welding machine body, a fixed support plate movably sleeved inside the fixed sleeve plate, a fixed stop block fixedly connected to one end of the fixed support plate, an assembly fixedly connected between the other ends of the two fixed support plates, a fixed groove opened on the side wall of the fixed support plate, a fixed tooth groove opened at the bottom of the fixed groove, a cooling component connected to the back of the welding machine body, and a fixed component connected to the side wall of the fixed sleeve plate;

[0007] An assembly kit is rotatably connected through the surface of the assembly component. An assembly stop is fixedly sleeved on the outer wall of the assembly kit. An assembly toothed ring is fixedly sleeved on the outer wall of the assembly kit. An adjustment component is connected to the back of the assembly component.

[0008] As a further description of the above technical solution: the cooling assembly includes a mounting shell fixedly connected to the back of the welding machine body, and a mounting bracket is fixedly connected between the two sides of the inner wall of the mounting shell, which serves to provide support.

[0009] As a further description of the above technical solution: a mounting motor is fixedly connected to the back of the mounting bracket, and the output shaft of the mounting motor passes through the mounting bracket and is fixedly connected to the mounting fan blades. The mounting motor serves to drive the mounting fan blades to rotate.

[0010] As a further description of the above technical solution: the fixing component includes a fixing housing fixedly connected to the side wall of the fixing sleeve plate, a fixing motor fixedly connected between the two sides of the inner wall of the fixing housing, and a fixing rod fixedly connected to the output end of the fixing motor, so as to drive the fixing rod to rotate.

[0011] As a further description of the above technical solution: the end of the fixing rod passes through the fixing shell and the fixing sleeve and extends into the fixing groove. The end of the fixing rod is fixedly connected to a fixing gear, which meshes with its corresponding fixing tooth groove. Through the meshing of the fixing gear and the fixing tooth groove, the fixing support plate on the fixing tooth groove is driven to move along the inside of the fixing sleeve.

[0012] As a further description of the above technical solution: the adjustment component includes an adjustment bracket fixedly connected to the back of the assembly, and an adjustment motor is fixedly connected to the back of the adjustment bracket, which drives the adjustment gear to rotate.

[0013] As a further description of the above technical solution: the output shaft of the adjusting motor passes through the assembly and is fixedly connected to an adjusting gear, which meshes with the assembly gear ring, thereby driving the assembly gear ring to rotate.

[0014] This utility model has the following beneficial effects:

[0015] The cooling assembly allows the mounting motor to drive the mounting fan blades to rotate, thus blowing air to cool the welding machine body. The fixing assembly allows the adjusting motor to drive the adjusting gear to rotate, which in turn drives the mounting kit on the mounting ring to rotate along the direction of the assembly. The mounting kit then drives the mounting stop to rotate to the appropriate angle. The adjusting assembly allows the fixing rod and fixing gear on the fixing motor to rotate. Because the fixing gear meshes with its corresponding fixing tooth groove, it causes the fixing support plate on the fixing tooth groove to slide inside the fixing sleeve. Then, the fixing support plate drives the assembly to move, and the assembly also drives the mounting kit and the assembly stop to adjust the welding rod on the welding machine body to the appropriate distance for protection. This allows for protection based on different welding rod lengths and angles, thereby improving the performance. Attached Figure Description

The output shaft of the mounting motor 4 passes through the mounting bracket 3 and is fixedly connected to a mounting fan blade 5. The mounting motor 4 drives the mounting fan blade 5 to rotate and blow air.

[0024] A fixing assembly is connected to the side wall of the fixing sleeve 7. The fixing assembly includes a fixing housing that is fixedly connected to the side wall of the fixing sleeve 7. A fixing motor 10 is fixedly connected between the two sides of the inner wall of the fixing housing. A fixing rod 11 is fixedly connected to the output end of the fixing motor 10. The end of the fixing rod 11 passes through the fixing housing and the fixing sleeve 7 and extends into the fixing groove. A fixing gear 12 is fixedly connected to the end of the fixing rod 11. The fixing gear 12 meshes with its corresponding fixing tooth groove 9. The fixing assembly serves to drive the fixing support plate 8 to move inside the fixing sleeve 7.

[0025] A controller is connected to the side wall of the welding machine body 1. An assembly kit 14 is rotatably connected through the surface of the assembly 13. An assembly stop 15 is fixedly sleeved on the outer wall of the assembly kit 14. An assembly gear ring 16 is fixedly sleeved on the outer wall of the assembly kit 14.
