Technical Field

[0001] This application relates to the field of wire filling mechanism technology, specifically a wire filling mechanism for a welding torch. Background Technology

[0002] A welding torch is a tool that converts the energy output from welding power equipment (such as an arc welding power source) into welding heat and continuously feeds welding materials (such as welding wire) and protective media (such as gas) to perform normal welding. It is a key instrument in the welding process, and through a specific structure and working method, it enables a strong connection to be formed between the welding materials and the workpiece being welded.

[0003] Currently, the welding torch equipment we use lacks a specific mechanism to guide the welding wire directly below the tungsten electrode of the welding torch during automatic welding. Furthermore, it cannot adjust the feeding height and angle of the welding wire according to the welding process requirements. This can lead to problems such as the welding wire deviating from the welding area, poor molten pool formation, and unstable weld quality.

[0004] Therefore, it is necessary to provide a wire-filling mechanism for the welding torch to solve the above problems. Utility Model Content

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] like Figure 1 - Figure 5As shown, this application provides a wire filling mechanism for a welding torch, including a wire filling assembly 10. The wire filling assembly 10 includes a welding torch 11, and a connecting strip 12 is fixedly installed on the welding torch 11. The connecting strip 12 can be connected to an external power supply mechanism, so that the wire filling assembly 10 as a whole can perform welding work.

[0029] The bottom of the welding torch 11 is provided with a wire feeding copper tube 121, and a filler nozzle 122 is fixedly installed on the wire feeding copper tube 121. The filler nozzle 122 can be filled with welding wire, and the welding wire is close to the bottom of the welding torch 11. Thus, the welding wire installed by the filler nozzle 122 can be melted by passing through the bottom of the welding torch 11, and the molten welding wire will form a strong connection between the welding material and the workpiece being welded.

[0030] The welding torch 11 is rotatably connected to clamping blocks a14 and b15. Both clamping blocks a14 and b15 have arc surfaces on their outer sides, which can be adapted to the outer side of the welding torch 11. Thus, clamping blocks a14 and b15 can rotate around the welding torch 11. The specific connection method between clamping block a14 and the wire feeding copper tube 121 is described below. After rotation, clamping blocks a14 and b15 can arbitrarily adjust the wire feeding copper tube 121 in the circumferential direction, while the wire feeding position of the filler nozzle 122 remains unchanged, thereby facilitating the circumferential angle adjustment of the filler assembly 10.

[0031] Meanwhile, a limiting ring a110 is fixedly installed on the outer side of the welding torch 11, and both the clamping blocks a14 and b15 are provided with limiting grooves a111 that are compatible with the limiting ring a110. The limiting grooves a111 can be located at the limiting ring a110, so that when the clamping blocks a14 and b15 rotate on the welding torch 11, the limiting grooves a111 are limited at the limiting ring a110, thereby preventing the clamping blocks a14 and b15 from moving up and down, and also improving the rotational stability of the clamping blocks a14 and b15.

[0032] Furthermore, a connecting rod 18 is fixedly installed on the clamping block b15. The end of the connecting rod 18 is threaded, and the connecting rod 18 can pass through the interior of the clamping block a14. A nut 19 is threadedly connected to the thread of the connecting rod 18, and the nut 19 can be located on the clamping block a14. When the clamping blocks a14 and b15 need to be rotated and adjusted on the welding torch 11, the nut 19 can be loosened on the thread of the connecting rod 18, so that the clamping blocks a14 and b15 can move on the outside of the welding torch 11, thereby allowing the clamping blocks a14 and b15 to be rotated and adjusted. Similarly, when it is necessary to fix the clamping blocks a14 and b15 on the welding torch 11, the nut 19 can be tightened on the thread of the connecting rod 18, so that the clamping blocks a14 and b15 can be fixed and bound on the outside of the welding torch 11.

[0033] A connecting plate 16 is snapped onto the clamping block a14. A bolt a17 is provided between the connecting plate 16 and the clamping block a14, so that the height of the connecting plate 16 can be adjusted by the bolt a17. At the same time, the bottom of the connecting plate 16 is inclined. A fixing block 114 is mounted on the bottom bearing of the connecting plate 16. A nut 112 is provided between the fixing block 114 and the support bar 116. The nut 112 is threaded on the clamping block a14, and the bottom of the nut 112 is bearing connected to the fixing block 114. Thus, the nut 112 can be rotated so that the angle of the fixing block 114 can be adjusted at the bottom of the clamping block a14. In this way, the wire feeding assembly 10 can increase the adjustment range of the wire feeding angle and height.

[0034] Meanwhile, a spring 113 is installed on the nut 112 between the clamping block a14 and the fixing block 114. The spring 113 can compress and tighten the nut 112 during adjustment, which facilitates adjustment. At the same time, when the filling wire assembly 10 is installed in the vertical direction, the spring 113 has a certain buffering protection function.

[0035] The fixed block 114 has a slide rail 115, and a support bar 116 is slidably installed inside the slide rail 115. A base block 117 is fixedly installed on the support bar 116, and the wire feeding copper tube 121 is snapped into the inside of the base block 117. Thus, the wire feeding copper tube 121 can be installed through the base block 117. A bolt b118 is threadedly connected between the base block 117 and the slide rail 115. The bolt b118 can be loosened, so that the support bar 116 can slide and adjust the base block 117 at the slide rail 115. This allows the wire feeding assembly 10 to increase the adjustment range of the wire feeding angle and height. Tightening the bolt b118 will stop the support bar 116 from moving.

[0036] The fixing block 114 has a limiting groove b120 near the slide rail 115, and a limiting ring b119 is fixedly installed on the outer side of the support bar 116. The limiting ring b119 can be located inside the limiting groove b120. When the support bar 116 moves, it will move synchronously with the limiting ring b119 at the limiting groove b120. The limiting ring b119 prevents the support bar 116 from moving left and right, thus preventing the support bar 116 from falling off when sliding on the slide rail 115. It also greatly improves the stability of the support bar 116 and the base block 117.

[0037] A protective plate 123 is fixedly installed on one side of the clamping block a14. The protective plate 123 can protect the outside of the filler nozzle 122, thereby blocking part of the sparks generated when the protective plate 123 is working with the welding wire, thus improving the safety of the welding wire operation. Furthermore, a bolt c124 is provided on the protective plate 123. The bolt c124 can pass through the protective plate 123 and be threaded to the clamping block a14, so that the protective plate 123 can be disassembled or installed later through the bolt c124.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
