Abstract
Description
Technical Field
[0001] This disclosure relates to the field of welding torches, and particularly to a welding torch head and a welding torch. Background Technology
[0002] Argon arc welding, also known as argon gas shielded welding, is a welding technique that uses argon gas as a shielding gas. Specifically, it involves circulating argon gas around the arc welding area to isolate the weld zone from air and prevent oxidation.
[0003] Existing TIG welding torches typically consist of a torch body and a gripper, and are mostly fixed structures. Whether handheld or automatically clamped, the angles of the torch body and gripper are difficult to adjust. When the welding surface is within a relief groove or other irregularly shaped surface, the welding difficulty increases significantly if the angle between the torch body and gripper cannot be adjusted. Additionally, while some welding torches exist that allow for angle adjustment of the torch body and gripper, these only allow for angle adjustment and not for adjusting the distance between the torch body and the gripper. Utility Model Content

Figure 2 This is a schematic diagram of another structure of the welding torch head provided in an embodiment of this disclosure. Figure 3 This is another schematic diagram of the structure of the welding torch head provided in the embodiments of this disclosure. Figure 4 This is a schematic diagram of a gripper in a welding torch head provided in an embodiment of this disclosure. Figure 1 and Figure 2 The angles of the gun head and the grip are different. Figure 1 and Figure 3 The connection points between the gun head and the grip are different.
[0034] Reference Figures 1 to 4The welding torch head includes: a torch head body 10, a grip 11, and a positioning member 12. One of the torch head body 10 and the grip 11 is provided with a first connecting structure 13 at a first position and a second connecting structure 14 at a second position. The other of the torch head body 10 and the grip 11 is provided with a mating structure 15, which can be rotatably connected to either the first connecting structure 13 or the second connecting structure 14. The positioning member 12 is detachably connected to the torch head body 10 and has a locked state and an unlocked state. In the locked state, the positioning member 12 is connected to the torch head body 10 and engages with the grip 11. In the unlocked state, the positioning member 12 is separated from the torch head body 10.
[0035] The gun head body 10 is used for welding operations.
[0036] The grip 11 is for the user to hold.
[0037] The first and second positions are the two connection points between the gun head body 10 and the grip 11. Figure 1 and Figure 2 In the middle, the gun head body 10 and the grip 11 are connected at the first position, in Figure 3 In the middle, the gun head body 10 and the grip 11 are connected at a second position. The connection position between the gun head body 10 and the grip 11 can be adjusted, so that the distance between the grip position of the gun head body 10 and the grip 11 can be changed, thereby improving the practicality of the welding gun head.
[0038] The positioning component 12 is used to allow the gun head body 10 and the grip 11 to rotate in the unlocked state. The user can adjust the angle between the gun head body 10 and the grip 11 according to the welding requirements, and fix the angle between the gun head body 10 and the grip 11 in the locked state.
[0039] In some embodiments, the mating structure 15 is a shaft hole, and the first connecting structure 13 and the second connecting structure 14 are convex shafts, with the shaft hole capable of housing the convex shafts. This configuration allows the shaft hole to be fitted onto the outer circumference of either of the two convex shafts, enabling adjustment of the two connection positions between the gun head body 10 and the convex shafts.
[0040] In some embodiments, the grip 11 is provided with a connecting plate 16, and the end of the connecting plate 16 facing the gun head body 10 is provided with a plurality of notches 17 arranged around the rotation axis; the positioning member 12 is a knob, in the locked state, part of the knob is engaged in the notch 17 and connected to the gun head body 10, and in the unlocked state, the knob is separated from the connecting plate 16.
[0041] The axis of rotation is the axis of rotation of the gun head body 10 and the grip 11. That is, the gun head body 10 and the grip 11 rotate relative to each other around the axis of rotation.
[0042] The knob is detachably connected to the gun head body 10. Specifically, the knob includes a connected rod and a cap. The rod is threadedly connected to the gun head body 10. When the user needs to adjust the angle between the gun head body 10 and the grip 11, they can rotate the cap to rotate the rod and remove the knob. At this time, the positioning member 12 is in the unlocked state. When the gun head body 10 and the grip 11 are adjusted to a preset angle, the user can engage the rod in a notch 17 of the connecting plate 16 and pass it through the notch 17 to connect to the gun head body 10, so that the angle between the gun head body 10 and the grip 11 can be fixed.
[0043] Figure 5 This is a schematic diagram of the structure of the torch head body in an embodiment of the present disclosure.
[0044] Reference Figure 4 and Figure 5 In some embodiments, the mating structure 15 is disposed on the connecting plate 16, and the first connecting structure 13 and the second connecting structure 14 are disposed on the gun head body 10.
[0045] In some embodiments, the gun head body 10 is provided with a first screw hole 101 and a second screw hole 102. In a first position, the knob is threadedly connected to the first screw hole 101, and in a second position, the knob is threadedly connected to the second screw hole 102.
[0046] The first position and the second position are two connection positions between the gun head body 10 and the grip 11. When the mating structure 15 is connected to the first connection structure 13 in the first position, the knob is threadedly connected to the first threaded hole. When the mating structure 15 is connected to the second connection structure 14 in the second position, the knob is threadedly connected to the second threaded hole.
[0047] Continue to refer to Figure 4 and Figure 5 In some embodiments, the first screw hole 101, the first connecting structure 13, the second screw hole 102, and the second connecting structure 14 are located on the same straight line, with the first connecting structure 13 located between the first screw hole 101 and the second screw hole 102, and the second screw hole 102 located between the first connecting structure 13 and the second connecting structure 14. Because the shaft hole is provided on the connecting plate 16, and the notch 17 is located at the end of the connecting plate 16 facing the gun head body 10, the first screw hole 101 should be provided above the first connecting structure 13, and the second screw hole 102 should be provided above the second connecting structure 14.
[0048] The distance between the first screw hole 101 and the first connecting structure 13 is equal to the distance between the second screw hole 102 and the second connecting structure 14.
[0049] Reference Figures 3 to 5In some embodiments, the connecting plate 16 is provided with a relief groove 161, and when the first connecting structure 13 is connected to the mating structure 15, the second connecting structure 14 is placed in the relief groove 161.
[0050] The clearance groove 161 provides space for the second connection structure 14 when the first connection structure 13 is connected to the mating structure 15.
[0051] Figure 6 This is a schematic diagram illustrating another structural design of the welding torch head provided in an embodiment of this disclosure. Figure 6 for Figure 1 Side view.
[0052] Reference Figure 1 and Figure 6 In some embodiments, two of each of the first connecting structure 13, the second connecting structure 14, and the mating structure 15 are provided, and the two first connecting structures 13, the two second connecting structures 14, and the two mating structures 15 are provided in a one-to-one correspondence; two positioning members 12 are provided, and the two positioning members 12 are positioned opposite each other on both sides of the gun head body 10. This arrangement can improve the connection stability between the gun head body 10 and the grip member 11.
[0053] Continue to refer to Figure 6 In some embodiments, the gun head body 10 is provided with a first pipe 103, the grip 11 is provided with a second pipe 111, and the welding gun head also includes a rubber tube 18, which connects the first pipe 103 and the second pipe 111.
[0054] The rubber tube 18 connects the first pipe 103 and the second pipe 111 so that the safety gas in the second pipe 111 of the grip 11 can be delivered through the rubber tube 18 to the first pipe 103 in the gun head body 10 for the delivery of safety gas to complete the welding.
[0055] In the aforementioned welding gun head, the first connecting structure 13 or the second connecting structure 14 can be connected to the mating structure 15, allowing the gun head body 10 and the grip 11 to be rotatably connected. Adjusting the positioning member 12 to the unlocked state allows the user to adjust the angle between the gun head body 10 and the grip 11 as needed. Then, adjusting the positioning member 12 to the locked state fixes the angle between the gun head body 10 and the grip 11. Therefore, the angle between the gun head body 10 and the grip 11 in the welding gun head provided in this embodiment is adjustable. Furthermore, the mating structure 15 can be connected to the first connecting structure 13 or the second connecting structure 14, allowing the distance between the gun head body 10 and the grip position to be changed.
[0056] According to some embodiments of this disclosure, another aspect of this disclosure also provides a welding torch, including the welding torch head described in any of the above embodiments.
[0057] A welding torch is a tool used to perform welding operations.
[0058] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes in form and detail may be made without departing from the spirit and scope of this disclosure. Any person skilled in the art can make various alterations and modifications without departing from the spirit and scope of this disclosure; therefore, the scope of protection of this disclosure should be determined by the scope defined in the claims.
