Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and particularly to a welding torch with a clamping assembly. Background Art

[0002] A welding torch with a clamping assembly is a specially designed welding tool. It adds a clamping assembly on the basis of a traditional welding torch, which assists the welding process to a certain extent, such as helping welders better control the welding angle and force, and improving the welding precision and efficiency.

[0003] During the welding process, the user needs to operate the welding torch with one hand, and the other hand needs to cooperate with the welding torch to deliver the welding wire. When welding small components onto a small circuit board, the welding torch and the welding wire come into contact with the component and the surface of the circuit board. The circuit board and the component are very likely to slide, resulting in unsuccessful welding. Moreover, the user has no extra hand to control the contact position between the circuit unit and the circuit board, making the welding process very complicated. Although there are some fixing jigs on the market that use universal tubes and clips, in actual welding, when welding a cable to a circuit board, some cables are very thin and very soft, without self-supporting force. If using clips to clamp, due to the lack of self-supporting force of the cable, the head of the cable cannot be well controlled, resulting in the need for multiple adjustments during welding, leading to low welding efficiency.

[0004] In view of this, the present invention proposes a welding torch with a clamping assembly to solve the above technical problems. Summary of the Invention

[0005] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments.

At the same time, the user can rotate the turntable, so that the turntable drives the universal tube and the circuit board to rotate, thereby achieving a suitable welding angle and improving the welding efficiency. When encountering a welding cable, the user can introduce the cable to be welded into the universal positioning tube, then fix the head of the cable using the fixing component, and then control the position of the head of the cable by adjusting the universal positioning tube to reach a suitable welding position, eliminating the cumbersome operation of repeatedly adjusting the cable position during welding due to the softness and lack of support of the cable, and further improving the welding efficiency.

[0012] As a preferred solution of the welding torch with a clamping assembly provided by the present invention, the gas collecting unit includes a gas storage pipe, which is fixedly connected to the back plate. A piston is slidably connected in the gas storage pipe. One end of the piston close to the slider is fixedly connected with a push rod, and the push rod extends out of the gas storage pipe. The push rod is on the movement path of the slider. One end of the gas storage pipe away from the slider is fixedly connected with the gas guide pipe. One end of a spring is fixedly connected to the end of the piston away from the slider, and the other end of the spring is fixedly connected to the bottom of the gas storage pipe.

[0013] As a preferred solution of the welding torch with a clamping assembly provided by the present invention, an exhaust valve and an air suction pipe are fixedly connected to the gas storage pipe, and one-way valves are provided in both the exhaust valve and the air suction pipe.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0034] Embodiment

[0035] Such as Figures 1 - 7As shown in the figure, a welding torch with a clamping assembly includes a fixture table 1, on which a fixture assembly 4 is provided. The fixture assembly 4 includes a turntable 41 rotatably connected to the fixture table 1. Four groups of universal pipes 42 are provided on the turntable 41. A wire clamping assembly 5 is provided at the end of one of the universal pipes 42. The wire clamping assembly 5 includes a back plate 51 fixedly connected to the end of the universal pipe 42. A chute 52 is provided on the back plate 51, and a slider 53 is slidably connected in the chute 52. A universal positioning pipe 55 is fixedly connected to the slider 53. A fixing assembly 6 is provided on the universal positioning pipe 55. An extension assembly 7 for pulling the cable is also provided on the universal positioning pipe 55;

[0036] The ends of three of the four groups of universal pipes 42 are fixedly connected with first fixing clips 43;

[0037] A welding torch holder 2 is also fixedly connected to the fixture table 1, and a welding torch 3 is placed in the welding torch holder 2;

[0038] A first positioning knob 54 is provided on the slider 53, and the first positioning knob 54 is used to fix the positions of the slider 53 and the universal positioning pipe 55.

[0039] In the embodiment, the user can clamp the circuit board or component to be welded by the first fixing clip 43, and then adjust the universal pipe 42 to reach a convenient welding angle. At the same time, the user can rotate the turntable 41, so that the turntable 41 drives the universal pipe 42 and the circuit board to rotate, so as to reach a suitable welding angle. In traditional welding, the user needs to control the welding torch 3 with one hand and the welding wire with the other hand, and there is no extra hand to control the circuit board to be welded. Especially for a circuit board with a small volume, when the welding torch 3, the welding wire and its surface come into contact, the circuit board is very likely to slide, resulting in unsuccessful welding. At the same time, when welding a small circuit unit to the circuit board, the user has no extra hand to control the contact position between the circuit unit and the circuit board, resulting in a very complicated welding process.

[0040] It should be noted that one of the universal pipes 42 in the present invention is particularly used for clamping the cable for welding. During the welding process, it is necessary to weld the cable to the circuit board, but some cables are very thin and very soft, and they have no self-supporting force. If the first fixing clip 43 is used for clamping, because the cable has no self-supporting force, the head of the cable cannot be well controlled, resulting in multiple adjustments during welding and low welding quality. When the wire clamping assembly 5 in the present invention is used, first, the cable to be welded is introduced into the universal positioning pipe 55, and the head of the cable is kept protruding from the universal positioning pipe 55 for subsequent welding. Then, the head of the cable is fixed by the fixing assembly 6, and then the position of the head of the cable is controlled by adjusting the universal positioning pipe 55 to reach a suitable welding position.

[0041] As Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, the fixing component 6 includes a gas collecting unit 61. One end of the universal positioning tube 55 away from the universal tube 42 is fixedly connected with an airbag 64. The gas collecting unit 61 is fixedly connected with the airbag 64 through an air duct 62. A tightening winder 63 is fixedly connected to the back plate 51, and the tightening winder 63 is used to tighten the air duct 62;

[0042] The gas collecting unit 61 includes a gas storage tube 611. The gas storage tube 611 is fixedly connected to the back plate 51. A piston 614 is slidably connected in the gas storage tube 611. One end of the piston 614 close to the slider 53 is fixedly connected with a push rod 612. The push rod 612 extends out of the gas storage tube 611. The push rod 612 is on the movement path of the slider 53. One end of the gas storage tube 611 away from the slider 53 is fixedly connected with the air duct 62. One end of a spring 613 is fixedly connected to the end of the piston 614 away from the slider 53, and the other end of the spring 613 is fixedly connected to the bottom of the gas storage tube 611;

[0043] An exhaust valve 66 and an air suction pipe 65 are respectively fixedly connected to both sides of the gas storage tube 611. Check valves are arranged in both the exhaust valve 66 and the air suction pipe 65.

[0044] In the embodiment, after the cable is introduced into the universal positioning tube 55, the user pushes the slider 53 to drive the universal positioning tube 55 and the cable to slide in the chute 52. The universal positioning tube 55 drives the cable to extend out of the back plate 51 and approach the circuit board. During the sliding of the slider 53, the slider 53 pushes the push rod 612, and the push rod 612 drives the piston 614 to slide in the gas storage tube 611 and compress the spring 613. When the piston 614 slides in the gas storage tube 611, it pushes the air in the gas storage tube 611 to enter the airbag 64 through the air duct 62. The airbag 64 is annular and fits on the inner wall of the end of the universal positioning tube 55. After the airbag 64 has gas entering, it expands to fix the head of the cable (the airbag 64 has elasticity and can fix cables of different thicknesses). The tightening winder 63 can wind up the air duct 62 (the tightening winder 63 is a prior art and will not be elaborated here too much) to prevent the air duct 62 from being wound. After the universal positioning tube 55 extends out, the position of the universal positioning tube 55 is fixed by the first positioning knob 54.

[0045] It should be noted that an exhaust valve 66 is installed on the gas storage pipe 611. Since the volume of the gas filled inside the airbag 64 is different when fixing cables with different thicknesses, the exhaust valve 66 is used to discharge the excess gas filled into the airbag 64 from the gas storage pipe 611 and maintain the air pressure inside the airbag 64 at the same time.

[0046] After the welding is completed, when the user slides the slider 53 and the universal positioning pipe 55 back to their original positions, since the push rod 612 is no longer under the thrust of the slider 53, the spring 613 inside the gas storage pipe 611 extends and drives the piston 614 to slide back to its original position. At this time, the guide pipe 62 generates suction, and at the same time the airbag 64 contracts, and the air intake pipe 65 intakes gas (there is a one-way valve in the air intake pipe 65 that can only intake gas and cannot exhaust gas, and there is also a one-way valve in the exhaust valve 66 that can only exhaust gas and cannot intake gas). After the airbag 64 contracts, it no longer fixes the cable. At the same time, the cable has been welded to the circuit board at this time. Therefore, when the slider 53 drives the universal positioning pipe 55 to slide back to its original position, the welded cable just separates from the universal positioning pipe 55.

[0047] As Figures 4 - 7 shown, the extension assembly 7 includes a fixed bracket 72. One end of the universal positioning pipe 55 away from the slider 53 is fixedly connected with the fixed bracket 72. A steel sheet 71 is slidably connected inside the fixed bracket 72. One end of the steel sheet 71 away from the slider 53 is fixedly connected with a second fixed clamp 74. A second positioning knob 73 for fixing the position of the steel sheet 71 is provided on the fixed bracket 72;

[0048] The steel sheet 71 is elastic and can bend along with the universal positioning pipe 55.

[0049] In the embodiment, the already fixed cable is clamped by the second fixed clamp 74. When welding, if the cable is not successfully welded to the circuit board, a part of the cable will be consumed at this time. At this time, the steel sheet 71 can be pushed. The steel sheet 71 pulls out a part of the cable from the universal positioning pipe 55 through the second fixed clamp 74 (although the airbag 64 fixes the cable, under the action of an increased pulling force, the cable will slide relative to the airbag 64). Subsequently, the position of the steel sheet 71 and the cable is fixed by the second positioning knob 73 for the second welding.

[0050] The steel sheet 71 is an elastic steel sheet 71 and can bend along with the universal positioning pipe 55.

[0051] The working process is as follows:

[0052] First, clamp components such as the circuit board to be welded onto the first fixing clamp 43, and adjust the universal pipe 42 to reach a convenient welding angle. At the same time, the user can rotate the turntable 41, so that the turntable 41 drives the universal pipe 42 and the circuit board to rotate, thereby achieving a suitable welding angle. When welding soft cables, the first fixing clamp 43 can no longer meet the requirement of fixing the cable. At this time, import the cable to be welded into the universal positioning pipe 55, and keep the head of the cable protruding from the universal positioning pipe 55 for subsequent welding. Then, push the slider 53 to drive the universal positioning pipe 55 and the cable to slide in the chute 52. The universal positioning pipe 55 drives the cable to extend out of the backboard 51 and approach the circuit board. During the sliding process of the slider 53, the slider 53 pushes the push rod 612, and the push rod 612 drives the piston 614 to slide in the air storage pipe 611 and compress the spring 613. When the piston 614 slides in the air storage pipe 611, it pushes the air in the air storage pipe 611 to enter the airbag 64 through the air guide pipe 62. The airbag 64 is annular and fits on the inner wall of the end of the universal positioning pipe 55. After the airbag 64 has gas entering, it expands to fix the head of the cable. At the same time, after the universal positioning pipe 55 extends out, fix the position of the universal positioning pipe 55 through the first positioning knob 54. Then, control the position of the head of the cable by adjusting the universal positioning pipe 55 to reach a suitable welding position. During welding, if the cable and the circuit board are not successfully welded, at this time, a part of the cable will be consumed. At this time, the steel sheet 71 can be pushed. The steel sheet 71 pulls out a part of the cable from the universal positioning pipe 55 through the second fixing clamp 74. Then, fix the positions of the steel sheet 71 and the cable through the second positioning knob 73 for the second welding. When the welding is completed, when the user slides the slider 53 and the universal positioning pipe 55 back to the original position, since the push rod 612 is no longer subjected to the thrust of the slider 53, the spring 613 in the air storage pipe 611 extends and drives the piston 614 to slide back to the original position. At this time, the air guide pipe 62 generates suction, and at the same time, the airbag 64 contracts, and the air suction pipe 65 enters gas. After the airbag 64 contracts, it no longer has a fixing effect on the cable. At the same time, the cable has been welded to the circuit board at this time. Therefore, when the slider 53 drives the universal positioning pipe 55 to slide back to the original position, the welded cable just separates from the universal positioning pipe 55.
