Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire feeding technology for welding machines, and in particular to a wire feeding clamp for welding machines. Background Technology
[0002] In modern industrial production, welding, as a key joining process, is widely used in many fields such as machinery manufacturing, automotive industry, and aerospace. The wire feed clamp of a welding machine, as an important component of welding equipment, directly affects welding quality and production efficiency.
[0003] Traditional welding machine wire feed clamps typically employ a robust, integrated structure. Mechanically, they usually consist of a fixed clamping head and a matching clamping device. The clamping head securely holds the welding wire, while the clamping device uses bolts and other connecting components to fasten the clamping head, ensuring stable wire feeding during the welding process. The technical principle is based on mechanical clamping force, which tightly secures the welding wire within the clamping head. The power output of the wire feeding mechanism then propels the welding wire along a predetermined path towards the welding area.
[0004] A significant problem with existing technology is that the clamp must be completely disassembled each time the welding wire is changed. Because the chuck and clamping device are tightly connected, operators must spend considerable time unscrewing multiple bolts and other connectors to remove the old welding wire and replace it with the new one. This cumbersome process greatly increases operating time, especially in production scenarios where different materials and specifications of welding wire need to be frequently changed to meet diverse welding tasks. Frequent disassembly and installation of the clamp severely hinders the smoothness of continuous operation, significantly reducing the overall efficiency of the welding machine and failing to meet the urgent needs of modern industry for high-efficiency production. Therefore, a welding machine wire feeding clamp is proposed to solve these problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a welding machine wire feeding clamp, which aims to improve the problem that the clamp needs to be completely disassembled every time the welding wire is changed, which increases the time consumption and seriously affects the efficiency of continuous operation.

[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, by rotating the screw sleeve to disengage it from the side wall of the clamping plate, the clamping plate can be forced to rotate the rotating plate to rotate on the inner wall of the fixed plate, which achieves the effect of facilitating the connection of welding wire. This solves the problem that the clamp must be completely disassembled every time the welding wire is changed, which increases the time consumption and seriously affects the efficiency of continuous operation, and improves the convenience of the welding machine wire feeding clamp.
[0025] 2. In this utility model, the spring's rebound force drives the first hollow block at one end to move on the inner wall of the bracket, and then the rotating wheel moves along with the first hollow block, achieving the effect of adaptive clamping of the welding wire. This solves the problem that non-adaptive clamping is prone to uneven pressure due to welding wire tolerance, resulting in arc length fluctuations and increased welding spatter, and improves the versatility of welding machine wire feeding fixtures.

The support component is used to facilitate the connection of welding wire, increase the convenience of the welding machine wire feeding clamp, and thus improve the welding wire connection effect.
[0033] The support assembly includes a connecting plate 7, the bottom of which is fixedly connected to the top of the bracket 1. A second limiting post 19 is fixedly connected inside the connecting plate 7. A screw 8 is fixedly connected inside the second limiting post 19.

The side wall of the screw sleeve 9 is set on the side wall of the clamping plate 10. The support assembly is installed inside the bracket 1.
[0034] Reference Figure 1 and Figure 3 The connecting assembly includes a second hollow block 15, the side wall of which is fixedly connected to the inside of the bracket 1. The fixing assembly includes a hollow plate 17, the bottom of which is fixedly connected to the side wall of the bracket 1. A bolt 18 is provided inside the hollow plate 17. A spring 13 is provided on the side wall of the second hollow block 15. One end of the spring 13 is fixedly connected to the inside of the second hollow block 15, and the other end of the spring 13 is fixedly connected to a fixing ring 12. A first limiting post 14 is fixedly connected inside the fixing ring 12. The outer wall of the first limiting post 14 is provided on the inner wall of the spring 13. The outer wall of the first limiting post 14 is slidably connected to the inside of the second hollow block 15. A first hollow block 5 is fixedly connected to one end of the first limiting post 14. The side wall of the first hollow block 5 is slidably connected to the side wall of the bracket 1. A rotating wheel 11 is rotatably connected inside the first hollow block 5. The outer wall of the rotating wheel 11 is provided at one end of the wire feeding tube 2. The outer wall of the fixing ring 12 is provided on the side wall of the second hollow block 15.
[0035] Working principle: When using the wire feeding clamp of the welding machine, and to facilitate the connection of welding wire, firstly, the screw sleeve 9 needs to be rotated. The screw sleeve 9 is subjected to force and rotates on the outer wall of the screw rod 8. Then, during the process of the screw rod 8 being subjected to force, it rotates inside the second limiting post 19, and the screw rod 8 is limited by the second limiting post 19. Then, the second limiting post 19 rotates on the inner wall of the connecting plate 7. At the same time, when the screw sleeve 9 rotates, it will disengage from the side wall of the clamping plate 10. Then, the screw rod 8 can be moved to disengage from the inner wall of the clamping plate 10. Then, the rotating plate 6 can be moved. The rotating plate 6 is subjected to force and rotates inside the fixed plate 4. During the process of the rotating plate 6 being subjected to force, it will drive the rotating wheel 11 to rotate. Then, after the rotating plate 6 rotates, it will protrude into the bracket 1. After protruding into the bracket 1, the wire feeding tube 2 and the wire feeding post 16 will protrude, which can facilitate the passage of welding wire and achieve the effect of facilitating the connection of welding wire.
[0036] Then, the welding wire is adaptively clamped. The welding wire passes through the inside of the wire feeding tube 2 and then shuttles inside the bracket 1. At the same time, the rotating wheel 11 on the outer wall is driven to be stressed. During the movement of the rotating wheel 11, the first hollow block 5 on the outer wall is driven to move. At the same time, the first hollow block 5 is stressed and slides on the inner wall of the bracket 1. Then, during the stress on the first hollow block 5, the first limiting post 14 on the side wall is driven to move. During the movement of the first limiting post 14, it slides on the inner wall of the second hollow block 15. During the stress on the first hollow block 5, the spring 13 on the side wall is driven to contract. Then, the spring 13 is stressed and releases its rebound force, causing the first hollow block 5 to be stably attached to the outer wall of the welding wire, thus achieving the effect of adaptive clamping of the welding wire.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
