Description

Technical Field

[0001] This utility model relates to the field of welding gun technology, and in particular to a welding gun for flexible welding. Background Technology

[0002] A welding gun is a tool used for welding operations, commonly known as a welding torch or welding gun. Flexible welding guns are mainly used in situations where frequent movement or adjustment of position is required during the welding process, thereby improving work efficiency. Therefore, a flexible welding gun is used.

[0003] To address this, patent CN220259795U discloses a welding gun for circuit board soldering, comprising: a welding gun body, a heating head, and a wire feed tube. A swing rod is provided on one side of the welding gun body, elastically and movably connected to the side of the welding gun body. The first end of the swing rod extends to one side of the handle, and a protective cover is fixed to the second end of the swing rod. When the hand grips the handle, the first end of the swing rod is held, and the second end swings upward, causing the protective cover to swing upward synchronously, exposing the end of the heating head. When not in use, the hand is released from the handle, and the second end of the swing rod is not held. Under the action of elastic force, the second end of the swing rod can automatically swing downward to return to its original position, allowing the protective cover to cover the outside of the heating head, protecting it from burns to personnel or objects, thus ensuring high safety.

[0004] Although the welding guns used for circuit board soldering described above have protective features to prevent burns to personnel or objects, making them relatively safe, their inconvenience in adjusting direction and adapting to different soldering angles limits their efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a flexible welding gun to solve the problem that existing flexible welding guns are inconvenient to adjust in direction.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a flexible welding gun, including a mounting base;

[0007] Anti-slip pads are fixed on both sides of the top of the mounting base. A gun body is provided on the top of each anti-slip pad. A metal bellows is fixed to one end of the gun body, and a gun head is fixed to one end of the metal bellows.

[0008] The top of the mounting base is fixed with a fixing structure, and a housing is provided on one side of the mounting base. A handle is fixed to the bottom of the housing.

[0009] The housing has an adjustment structure inside, which includes an internal cavity inside the housing, a gear inside the internal cavity, a rotating shaft passing through the gear, a threaded column passing through the housing above the gear, and a limit seat rotatably connected to the bottom end of the threaded column.

[0010] When using this device, the adjustable structure allows for easy adjustment of the welding direction, thereby improving the working efficiency of the flexible welding gun. The fixed structure facilitates the installation of the gun body, thus enhancing the applicability of the flexible welding gun.

[0011] Preferably, the fixing structure includes a bracket, an electric push rod, a slide groove, a slider, and a pressure plate. The bracket is fixed to the top of the mounting base, and the electric push rod passes through the top of the bracket. Slide grooves are provided on both sides of the bracket, and sliders are provided inside the slide grooves. Pressure plates are fixed between adjacent sliders.

[0012] Preferably, the bottom end of the electric push rod is fixedly connected to the top end of the pressure plate, and the slider and the bracket form a sliding structure through a groove. Under the action of the slider, the stability of the pressure plate is enhanced when it moves, and the moved pressure plate causes the rubber pad to press against the top end of the gun body to fix the gun body.

[0013] Preferably, rubber pads are fixed to both sides of the bottom end of the pressure plate, and the pressure plate abuts against the top of the gun body through the rubber pads. The rubber pads increase the friction between the pressure plate and the gun body, preventing the gun body from shaking during operation.

[0014] Preferably, a rubber sleeve is fitted over the outer side of the handle. The rubber sleeve increases the friction between the palm and the handle, making it easier to hold.

[0015] Preferably, a handwheel is fixed to the top of the threaded column, and sliding rods penetrate the interior of both sides of the threaded column housing. The sliding rods enhance the stability of the limiting seat during movement. When the limiting seat separates from the gear, rotating the mounting base causes the mounting base to drive the gun head to rotate via the metal bellows, thereby changing the direction of the gun head.

[0016] Preferably, the limiting seat and the gear form an engaging structure. One end of the rotating shaft extends into the interior of the housing and forms a rotating structure with the housing. The other end of the rotating shaft extends into the exterior of the housing and is fixedly connected to one side of the mounting base. The sliding rod and the housing form a sliding structure, and the bottom end of the sliding rod is fixedly connected to the top end of the limiting seat. Under the action of the metal bellows, the tilt angle of the gun head can be changed at will. When the limiting seat abuts against the gear, the gear is in a fixed state under the limiting action of the limiting seat, thereby fixing the direction of the gun head.

[0017] The welding gun for flexible welding provided by this utility model has the following advantages:

[0018] By incorporating an adjustment structure, the stability of the limiting seat during movement is enhanced under the action of the slide rod. When the limiting seat and the gear separate, rotating the mounting base causes the mounting base to drive the gun head to rotate through the metal bellows, thereby changing the direction of the gun head. Under the action of the metal bellows, the tilt angle of the gun head can be changed at will. When the limiting seat and the gear come into contact, the gear is fixed under the limiting action of the limiting seat, thus fixing the direction of the gun head. This device enables easy adjustment of the welding direction, thereby improving the working efficiency of the flexible welding gun during use.

[0019] By incorporating a fixed structure, the stability of the pressure plate during movement is enhanced under the action of the slider. After movement, the pressure plate causes the rubber pad to press against the top of the gun body, thus fixing the gun body in place. The rubber pad increases the friction between the pressure plate and the gun body, preventing the gun body from shaking during operation. This device facilitates the installation of the gun body and improves the applicability of the flexible welding gun during use. Attached Figure Description

A gun body 2 is provided at the top of each anti-slip pad 8. A metal bellows 3 is fixed to one end of the gun body 2, and a gun head 4 is fixed to one end of the metal bellows 3. A fixing structure 5 is fixed to the top of the mounting base 1. The fixing structure 5 includes a bracket 501, an electric push rod 502, a slide groove 503, a slider 504, and a pressure plate 505. The bracket 501 is fixed to the top of the mounting base 1. An electric push rod 502 passes through the top of the bracket 501. Slide grooves 503 are provided on both sides of the bracket 501. Slide blocks 504 are provided inside the slide grooves 503. Pressure plates 505 are fixed between adjacent slide blocks 504. The bottom end of the electric push rod 502 is fixedly connected to the top end of the pressure plate 505. The slide blocks 504 and the bracket 501 form a sliding structure through the slide grooves 503. Rubber pads are fixed on both sides of the bottom end of the pressure plate 505. The pressure plate 505 abuts against the top end of the gun body 2 through the rubber pads.

[0028] Reference Figure 2 and Figure 3 As shown, the gun body 2 is placed on top of the anti-slip pad 8. Under the action of the anti-slip pad 8, the friction between the gun body 2 and the mounting base 1 is increased. The electric push rod 502 is activated, which drives the pressure plate 505 to move up and down. The pressure plate 505 drives the slider 504 to move inside the slide groove 503. Under the action of the slider 504, the stability of the pressure plate 505 during movement is enhanced. After moving, the pressure plate 505 drives the rubber pad to press on the top of the gun body 2 to fix the gun body 2. Under the action of the rubber pad, the friction between the pressure plate 505 and the gun body 2 is increased, preventing the gun body 2 from shaking during operation.

[0029] A housing 6 is provided on one side of the mounting base 1. A handle 7 is fixed to the bottom of the housing 6. An adjustment structure 9 is provided inside the housing 6. The adjustment structure 9 includes an internal cavity 901 inside the housing 6. A gear 902 is provided inside the internal cavity 901. A rotating shaft 903 passes through the inside of the gear 902. A threaded column 905 passes through the inside of the housing 6 above the gear 902. The bottom end of the threaded column 905 is rotatably connected to a limit seat 904. A handwheel 907 is fixed to the top end of the threaded column 905. Slide rods 906 pass through the inside of the housing 6 on both sides of the threaded column 905. The limit seat 904 and the gear 902 form a locking structure. One end of the rotating shaft 903 extends into the inside of the housing 6 and forms a rotating structure with the housing 6. The other end of the rotating shaft 903 extends into the outside of the housing 6 and is fixedly connected to one side of the mounting base 1. The slide rod 906 and the housing 6 form a sliding structure. The bottom end of the slide rod 906 is fixedly connected to the top end of the limit seat 904. A rubber sleeve is provided on the outside of the handle 7.

[0030] Reference Figure 4 and Figure 5 As shown, rotating the handwheel 907 causes the limiting seat 904 to move up and down. The limiting seat 904 then causes the sliding rod 906 to move inside the housing 6. Under the action of the sliding rod 906, the stability of the limiting seat 904 during movement is enhanced. When the limiting seat 904 and the gear 902 are separated, rotating the mounting base 1 causes the mounting base 1 to drive the gear 902 to rotate inside the housing 6 via the rotating shaft 903. At the same time, the mounting base 1 drives the gun head 4 to rotate via the metal bellows 3, thereby changing the direction of the gun head 4. Under the action of the metal bellows 3, the tilt angle of the gun head 4 can be changed at will. When the limiting seat 904 and the gear 902 come into contact, the gear 902 is in a fixed state under the limiting action of the limiting seat 904, thus fixing the direction of the gun head 4. Under the action of the rubber sleeve, the friction between the palm and the handle 7 is increased, so that the handle 7 can be held.
