Description

Technical Field

[0001] This utility model relates to the technical field of conductive nozzles for welding machines, specifically a conductive nozzle for welding machines that is easy to assemble. Background Technology

[0002] The contact tip is a consumable part and wear item in welding equipment. Located at the very end of the welding torch, it is used to feed the welding wire and transmit current. During welding, metal spatter easily adheres to the end face and outer wall of the contact tip, affecting wire feeding and gas flow. The contact tip should be inspected, cleaned, or replaced regularly. In practical use, the contact tip is generally threaded to the welding torch. Threaded connections require multiple rotations of the contact tip, which is time-consuming, labor-intensive, and inflexible, affecting work efficiency. Therefore, a contact tip for welding machines that is easy to assemble is provided. Utility Model Content

[0003] The purpose of this invention is to provide a welding machine contact tip that is easy to assemble, 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 conductive nozzle for an electric welding machine that is easy to assemble, comprising a conductive nozzle, a receiving tube provided on the outer side of the conductive nozzle, an outer connector provided on one side of the conductive nozzle, and an inner connector installed on one side of the outer connector, a hexagonal prism provided on one side of the inner connector, and a mating post provided on one side of the hexagonal prism, wherein the conductive nozzle, the outer connector, the inner connector, the hexagonal prism and the mating post are all provided with wire outlet holes, a positioning hole provided on the outer side of the outer connector, and an installation groove provided inside the inner connector, wherein a positioning pin and a spring are installed inside the installation groove.

[0005] Preferably, the cross-section of the outer connector is concave, and the cross-section of the inner connector is convex.

[0006] Preferably, the positioning holes are provided in two sets, and the positioning holes are symmetrically distributed on the outer mating head.

[0007] Preferably, there are two sets of mounting slots, and the mounting slots are symmetrically distributed on the inner mating head, with the positions of the two sets of mounting slots corresponding to the positions of the two sets of positioning holes.

[0008] Preferably, an adjusting ring is installed on one side of the gathering tube, and an anti-slip groove is provided on the outer side of the adjusting ring, and the gathering tube is conical in shape.

[0009] Preferably, the inner side of the adjusting ring is provided with an internal thread, the outer side of the conductive nozzle is provided with an external thread, and a threaded connection is formed between the conductive nozzle and the adjusting ring.

[0010] Preferably, the conductive nozzle has three sets of shrinkage slits inside, and the shrinkage slits are distributed in a ring shape inside the conductive nozzle.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) By setting an outer connector, an inner connector, a positioning hole, a mounting groove and a spring, the conductive nozzle can be quickly assembled. The cross-section of the outer connector is "U" shaped and the cross-section of the inner connector is "T" shaped. The outer connector can be quickly inserted into the inner connector. The cooperation between the positioning pin and the positioning hole can lock the outer connector and the inner connector together. Pressing the positioning pin can unlock the locking, which facilitates the quick assembly of the conductive nozzle and improves the flexibility of use.

[0013] (2) By setting a conductive nozzle, a coiling tube, an adjusting ring, and a shrinkage gap, the function of reducing the gap is realized. The threaded connection between the adjusting ring and the conductive nozzle can control the movement of the coiling tube on the conductive nozzle.

[0024] Please see Figure 1-5 This utility model provides an embodiment of a welding machine conductive nozzle that is easy to assemble, comprising a conductive nozzle 1, a receiving tube 2 disposed on the outer side of the conductive nozzle 1, an outer connector 5 disposed on one side of the conductive nozzle 1, and an inner connector 6 disposed on one side of the outer connector 5, a hexagonal prism 7 disposed on one side of the inner connector 6, and a mating post 8 disposed on one side of the hexagonal prism 7, wherein the conductive nozzle 1, the outer connector 5, the inner connector 6, the hexagonal prism 7, and the mating post 8 are all provided with wire outlet holes 10, and the outer connector 5 is provided with a positioning hole 12 on its outer side, and the inner connector 6... The device has an internal mounting groove 13, and a positioning pin 9 and a spring 14 are installed inside the mounting groove 13. The cross-section of the outer connector 5 is U-shaped, and the cross-section of the inner connector 6 is U-shaped. There are two sets of positioning holes 12, which are symmetrically distributed on the outer connector 5. There are two sets of mounting grooves 13, which are symmetrically distributed on the inner connector 6. The positions of the two sets of mounting grooves 13 correspond to the positions of the two sets of positioning holes 12. The positioning pin 9 can lock the position of the outer connector 5 by engaging with the inside of the positioning hole 12.

[0025] Specifically, as shown in the figure, during use, the outer connector 5 can be quickly plugged into the inner connector 6, and the cooperation between the positioning pin 9 and the positioning hole 12 can lock the outer connector 5 and the inner connector 6 together. Pressing the positioning pin 9 can unlock the lock, which facilitates the quick assembly of the conductive nozzle.

[0026] An adjusting ring 3 is installed on one side of the converging tube 2, and an anti-slip groove 4 is provided on the outer side of the adjusting ring 3. The converging tube 2 is tapered in shape. An internal thread is provided on the inner side of the adjusting ring 3. An external thread is provided on the outer side of the conductive nozzle 1. A threaded connection is formed between the conductive nozzle 1 and the adjusting ring 3. Three sets of shrinkage slits 11 are provided inside the conductive nozzle 1, and the shrinkage slits 11 are distributed in a ring shape inside the conductive nozzle 1.

[0027] Specifically, as shown in the figure, during use, the adjusting ring 3 is connected to the conductive nozzle 1 by a thread, which can control the movement of the coiling tube 2 on the conductive nozzle 1. The coiling tube 2 is tapered in shape, which can coil the conductive nozzle 1 inward. In conjunction with the distribution of the shrinkage slits 11, the gap between the wire outlet 10 and the welding wire is reduced, so that the conductive nozzle and the welding wire can make full contact.

[0028] Working principle: In use, first, take out the conductive tip of the welding machine and install the control docking post 8 with the welding machine. When it is necessary to disassemble the conductive tip 1, use a tool to press the two sets of positioning pins 9 into the interior of the mounting groove 13. Then, exert force to one side to control the separation of the outer connector 5 and the inner connector 6, so that the welding wire can be inserted into the interior of the wire outlet hole 10, which facilitates the quick assembly of the conductive tip. At the same time, when the gap between the conductive tip 1 and the welding wire is large, the adjusting ring 3 can be rotated. The threaded connection between the adjusting ring 3 and the conductive tip 1 can control the movement of the coiling tube 2 on the conductive tip 1. The coiling tube 2 is conical in shape, which can coil the conductive tip 1 inward. With the distribution of the shrinkage seam 11, the gap between the wire outlet hole 10 and the welding wire is reduced, so that the conductive tip and the welding wire can make full contact to ensure the welding quality. Finally, the use of the conductive tip of the welding machine is completed.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
