Description

Technical Field

[0001] This utility model relates to the field of conductive nozzle technology, specifically a welding conductive nozzle adapted to different welding torches. Background Technology

[0002] The welding contact tip is a key component in welding equipment, mainly used for conducting current and feeding welding wire. Existing contact tips generally connect to the welding torch via a threaded end at one end, such as the welding contact tip disclosed in application number 202422284141.2 in the Chinese Patent Document Database. However, this method requires a contact tip with an internal thread that is compatible with the welding torch of a specific size, making it not very versatile. Utility Model Content

[0003] The purpose of this invention is to provide a welding conductive tip that is compatible with different welding torches, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a welding conductive tip adapted to different welding torches, comprising a conductive tip body and a wire feeding hole disposed through the center of the conductive tip body. A positioning ring is provided vertically along one edge of the conductive tip body, and a plurality of inner support positioning plates are arranged in a circular array with the center of the positioning ring as the center. The plurality of inner support positioning plates can slide back and forth along the radial direction of the positioning ring. A driving member is provided on the outer peripheral wall of the conductive tip body, which moves back and forth along its length direction. A frustum-shaped curved surface with gradually increasing size from top to bottom is provided on the end of the driving member near the positioning ring. One end of the inner support positioning plate extends through the positioning ring to the side near the driving member and is fixed with a movable block. A slope tangent to the frustum-shaped curved surface is provided on one side of the bottom end of the movable block. The driving member moves along the length direction of the conductive tip body, driving the movable block to move horizontally along the radial direction of the positioning ring.

[0005] Furthermore, the end of the conductive nozzle body near the positioning ring is a cylindrical structure, and an external thread is provided on the outer side wall of the conductive nozzle body. The driving component is a ring structure sleeved on the outer peripheral wall of the conductive nozzle body, and an internal thread that mates with the external thread is provided on the inner side wall of the driving component.

[0006] Furthermore, each of the positioning rings is provided with a plurality of limiting sliding holes that correspond one-to-one with the inner support positioning plate along its radial direction, and each of the inner support positioning plates is fixed with a slider that is slidably disposed inside the limiting sliding hole at its bottom end. The slider passes through the limiting sliding hole and is fixedly connected to the movable block.

[0007] Furthermore, all the inner support positioning plates are arc-shaped plate structures with their centers facing the wire feeding hole.

[0008] Furthermore, the outer side wall of the inner support positioning plate is provided with anti-slip ridges.

[0009] Furthermore, the end of the conductive nozzle body away from the positioning ring is integrally provided with a tapered section whose size gradually decreases.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] (1) The welding conductive nozzle that is compatible with different welding guns has a positioning ring set at one end of the length of the conductive nozzle body, and an inner support positioning plate is movably set on the positioning ring by a driving component and a movable block. The spacing of the inner support positioning plate can be adjusted according to the inner diameter of the welding gun tube, and then inserted into the welding gun to achieve inner support fixation. It is compatible with different welding guns, has strong applicability, and is quick and convenient to assemble.

[0012] (2) By setting anti-slip ridges on the outer side wall of the inner support positioning plate, the internal positioning of the welding gun is more secure and reliable. Attached Figure Description

Therefore, they should not be construed as limitations on the present utility model.

[0018] Please see Figure 1-3 This utility model provides an embodiment of a welding conductive tip adapted to different welding torches, comprising a conductive tip body 1 and a wire feeding hole 101 penetrating the center of the conductive tip body 1. A positioning ring 2 is vertically extended along one edge of the conductive tip body 1, and four inner support positioning plates 3 are arranged in a circular array with the center of the positioning ring 2 as the center. Other numbers can also be set as needed. The inner support positioning plates 3 can slide back and forth along the radial direction of the positioning ring 2. The outer peripheral wall of the conductive tip body 1 is provided with a wire feeding hole 101 through the center of the conductive tip body 1. The moving drive component 4 has a frustum-shaped curved surface 401 with gradually increasing size from top to bottom at one end near the positioning ring 2. The conductive nozzle body 1 has a cylindrical structure at one end near the positioning ring 2, and an external thread 102 is provided on the outer side wall of the conductive nozzle body 1. The drive component 4 is a ring structure sleeved on the outer peripheral wall of the conductive nozzle body 1, and an internal thread that mates with the external thread 102 is provided on the inner side wall of the drive component 4. By rotating the drive component 4, it can be driven to move back and forth along the length direction of the conductive nozzle body 1, making installation convenient and quick.

[0019] In this embodiment, the end of the conductive nozzle body 1 away from the positioning ring 2 is integrally provided with a gradually decreasing diameter section 103, which facilitates welding positioning.

[0020] One end of the inner support positioning plate 3 extends through the positioning ring 2 to the side near the driving component 4 and is fixed with a movable block 5. The bottom side of the movable block 5 is provided with an inclined surface tangent to the frustum surface 401. The driving component 4 moves along the length direction of the conductive nozzle body 1, and drives the movable block 5 to move horizontally along the radial direction of the positioning ring 2. The distance between each inner support positioning plate 3 and the center of the positioning ring 2 is adjusted to perform inner support positioning for different welding guns 6.

[0021] Specifically, each of the positioning rings 2 has a number of limiting sliding holes 201 that correspond one-to-one with the inner support positioning plates 3 along its radial direction, and each of the inner support positioning plates 3 has a slider 301 that is slidably disposed inside the limiting sliding hole 201 at its bottom end. The slider 301 passes through the limiting sliding hole 201 and is fixedly connected to the movable block 5. The slider 301 is specifically a cuboid structure. While it can move back and forth along the radial direction of the positioning ring 2 inside the limiting sliding hole 201, it can prevent the inner support positioning plate 3 and the movable block 5 from rotating.

[0022] In this embodiment, the inner support positioning plates 3 are all arc-shaped plate structures with their centers facing the wire feeding hole 101, as shown in the attached figure. Figure 3 During assembly, the inner support positioning plate 3 is inserted into the welding gun 6, which can increase the contact area with the welding gun 6. The outer side wall of the inner support positioning plate 3 is provided with anti-slip ridges 302. In the prior art, the nozzle of the welding gun 6 is provided with internal threads and is threaded to the conductive seat. In this embodiment, by providing anti-slip ridges 302, it can be embedded in the internal threads, thereby improving the firmness of the inner support positioning plate 3.

[0023] Working principle: When in use, insert all four inner support positioning plates 3 into the barrel of the welding gun 6 until one end of the welding gun 6 abuts against the positioning ring 2. Then rotate the drive component 4 to move it along the outer peripheral wall of the conductive nozzle body 1 towards the end closer to the positioning ring 2. One side of the inner support positioning plate 3 abuts against the frustum surface 401, and then pushes the slider 301 to slide away from the center of the positioning ring 2 inside the limiting sliding hole 201 until the outer side walls of several inner support positioning plates 3 abut against the inner side wall of the welding gun 6 to achieve inner support fixation. It can be adapted to different welding guns 6, has strong applicability, and is quick and convenient to assemble.
