Description

Technical Field

[0001] This utility model relates to the field of welding torch technology, specifically to an anti-tangling welding torch mechanism for electric welding machines. Background Technology

[0002] Currently, welding torches are crucial tools in electric welding operations, and their reliability and operational flexibility directly impact welding efficiency and quality. Existing welding torches are generally connected to the power supply via cables, and the connection between the torch and cable mostly employs a rigid fixing structure or a threaded fastening joint.

[0003] In practical applications, the welding process requires operators to frequently adjust the welding torch's posture, causing the cable to easily become tangled or knotted due to twisting and swaying. In severe cases, this can even affect the stability of current transmission. This not only increases the burden of welding operations but may also damage the internal cables of the welding torch, shortening its service life. Although some welding torches are equipped with rotatable structures, their locking methods are complex and the rotation is not smooth, making it difficult to meet the flexibility requirements of high-frequency operations.

[0004] Furthermore, traditional techniques typically employ simple mechanical crimping or plug-in contacts in the electrical connection structure of welding torch connectors. Due to the lack of a reliable automatic locking and positioning mechanism, connector components are prone to loosening during prolonged vibration or frequent insertion and removal, leading to poor electrode contact and unstable current transmission. This not only affects welding quality but may also cause safety hazards such as overheating and sparking. Some improvements enhance connection stability by adding screw locking or snap ring structures, but these methods are cumbersome to install and remove, resulting in low maintenance efficiency and failing to meet the requirements for rapid replacement and efficient operation on the welding site.

[0005] In summary, existing welding torches for electric welding machines are inadequate in terms of anti-winding properties, quick assembly and disassembly, and stability of electrical connections at the joints. There is an urgent need for a new structure that can ensure the reliability of electrical connections while avoiding cable tangling and enabling quick assembly and disassembly. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is as follows: an anti-entanglement welding gun mechanism for an electric welding machine, comprising a welding gun, a cable, a connector, and a female connector body. The connector is rotatably mounted on one end of the welding gun, and the female connector body is fixed to one end of the cable. The female connector body includes a sleeve, a core ejector, several locking pins, and an unlocking magnetic ring. The surface of the connector is provided with a ring locking groove and several straight guide grooves, and several elastic contacts are arranged thereon. The inner side of the sleeve is provided with guide ridges corresponding one-to-one with the straight guide grooves, and an electrode slip ring is fixedly installed on its inner wall for electrical connection with the end of the cable. The locking pins are radially slidably arranged inside the sleeve, one end of which is provided with a permanent magnet slider, the core ejector is slidably sleeved inside the sleeve, and one end is connected to a first elastic element.

[0008] Specifically, this structure allows the connector to be quickly plugged into the female connector body to form a reliable electrical connection, while also having automatic locking and anti-loosening functions.

[0009] In a preferred example, the connector has a cylindrical structure, and the inner side of the sleeve has a sleeve hole that matches the connector. Both the core-removing part and the end of the connector are planar, and the sum of the original length of the first elastic element and the height of the core-removing part is equal to the depth of the sleeve hole in the inner cavity of the connector.

[0010] Specifically, this design ensures that the connector can be reliably ejected when the core is unlocked, and seals the end of the sleeve in the separated state to prevent foreign objects from entering and improve service life.

[0011] In a preferred example, the surface of the connector is provided with an oblique guide groove that is connected to the end of the straight guide groove, and the radial thickness of the straight guide groove is equal to the radial thickness of the guide ridge.

[0012] Specifically, the guide structure enables the connector to automatically correct its direction during insertion and removal, avoiding misalignment and jamming, and improving the smoothness of insertion.

[0013] In a preferred example, the inner side of the sleeve has several radial pin holes for guiding the sliding of the locking pin body. The outer periphery of the permanent magnet slider slides against the inner side of the pin holes.

[0014] Specifically, this structure ensures stable movement of the locking pin, preventing deviation or jamming and improving the reliability of locking and unlocking actions.

[0015] In a preferred example, one end of the permanent magnet slider is fixedly connected to a second elastic element for causing the permanent magnet slider to be pushed out radially and engage with the ring lock groove.

[0016] Specifically, the locking structure ensures a secure connection between the connector and the female connector body, preventing loosening and improving the stability of the electrical connection.

[0017] In a preferred example, the unlocking magnetic ring is slidably fitted onto the surface of the base. The unlocking magnetic ring is magnetic, and its magnetic poles are aligned with the magnetic poles of the permanent magnet slider. During unlocking, the magnetic force pulls the permanent magnet slider radially back, causing the locking pin to exit the ring lock groove, thus achieving rapid unlocking.

[0018] Specifically, this design enables quick disassembly of the connector without tools, improving ease of operation and maintenance efficiency.

[0019] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, the rotating connection between the connector and the welding torch allows the connector to rotate freely when engaged with the female connector body, effectively preventing tangling and twisting of the cable due to changes in posture during use, significantly improving operational flexibility and welding comfort. Simultaneously, the quick-plug structure of the connector and female connector body enables rapid assembly and disassembly without additional tools, facilitating maintenance and replacement and reducing downtime.

[0020] 2. In this utility model, the locking pin in the female connector body drives the permanent magnet slider to be pushed out radially under the pushing action of the second elastic element and reliably engages with the ring locking groove, thereby achieving stable locking of the connector part and the female connector body, thus ensuring stable electrical connection between the electrode slip ring and the elastic contact, avoiding problems such as unstable current or poor contact caused by loosening, and improving the safety and reliability of welding operations.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an anti-tangling welding gun mechanism for an electric welding machine.

[0026] Combination Figures 1-5 As shown, the present invention provides an anti-tangling welding torch mechanism for an electric welding machine, comprising a welding torch 100, a cable 110, a connector 200, and a female connector body 300. The connector 200 is rotatably mounted on one end of the welding torch 100, and the female connector body 300 is fixed to one end of the cable 110.

[0027] The female connector body 300 includes a sleeve 310, a core 320, a plurality of locking pins 330, and an unlocking magnetic ring 340 slidably sleeved on the surface of the locking pins 330. The surface of the connector portion 200 is provided with a ring locking groove 220 and a plurality of straight guide grooves 210, and the surface of the connector portion 200 is provided with a plurality of elastic contacts 230. The inner side of the sleeve 310 is provided with a plurality of guide ribs 311 arranged corresponding to the straight guide grooves 210. An electrode slip ring 312 is fixedly installed on the inner side of the sleeve 310, the electrode slip ring 312 being electrically connected to the end of the cable 110 and arranged corresponding to the elastic contacts 230. A plurality of locking pins 330 are radially slidably arranged on the inner side of the sleeve 310, and one end of each locking pin 330 is fixedly connected to a permanent magnet slider 331. The ejector core 320 is slidably sleeved on the inner side of the sleeve 310, and one end of the ejector core 320 is connected to a first elastic element 321, which is used to push the connector 200 away from the female connector body 300 after unlocking.

[0028] With the above structure, when the connector 200 mates with the female connector 300, the guide rib 311 and the straight guide groove 210 cooperate to guide the connector 200 to be inserted into the female connector 300 in the correct direction. After complete mating, the locking pin 330, under the pushing action of the second elastic element 332, drives the permanent magnet slider 331 to be pushed radially out and locked into the ring lock groove 220, thereby achieving reliable locking between the connector 200 and the female connector 300.

[0029] In this embodiment, the connector 200 has a cylindrical structure, and the inner side of the sleeve 310 has a sleeve hole adapted to the connector 200. Both the core retractor 320 and the end of the connector 200 have planar structures, and the sum of the original length of the first elastic member 321 and the height of the core retractor 320 is equal to the depth of the sleeve hole inside the connector 200. This design ensures that the core retractor 320 can push the connector 200 out to be flush with the end of the sleeve 310 when unlocking, preventing foreign objects from entering.

[0030] In this embodiment, the surface of the connector portion 200 is provided with an oblique guide groove that connects to the end of the straight guide groove 210. The radial thickness of the straight guide groove 210 is equal to the radial thickness of the guide ridge 311. This structure provides stable guidance during insertion and removal, prevents offset and jamming, and ensures smooth insertion.

[0031] In this embodiment, the inner side of the sleeve 310 is provided with a plurality of radial pin holes for guiding the sliding of the locking pin 330. The outer periphery of the permanent magnet slider 331 slides against the inner side of the pin holes, thereby enabling the locking pin 330 to move stably in the radial direction, ensuring reliable locking and unlocking actions.

[0032] In this embodiment, a second elastic element 332 is fixedly connected to one end of the permanent magnet slider 331. The second elastic element 332 is used to push the permanent magnet slider 331 radially outward, so that it reliably engages with the surface of the ring locking groove 220, thereby achieving a stable lock between the connector 200 and the female connector body 300.

[0033] In this embodiment, the unlocking magnetic ring 340 is slidably sleeved on the surface of the sleeve 310. The unlocking magnetic ring 340 is magnetic, and its magnetic poles are matched with the magnetic poles of the permanent magnet slider 331. When unlocking is required, the unlocking magnetic ring 340 slides along the surface of the sleeve 310, and the magnetic force pulls the permanent magnet slider 331 radially back, causing the locking pin 330 to exit the ring lock groove 220, thereby unlocking the connector 200 from the female connector 300. At this time, the core ejector 320, under the elastic recovery action of the first elastic element 321, quickly pushes the connector 200 out, completing the rapid separation.

[0034] Working principle and usage process of this utility model: The anti-tangle welding torch mechanism of this utility model mainly consists of a welding torch 100, a cable 110, a connector 200, and a female connector body 300. The connector 200 is provided with a ring locking groove 220, a straight guide groove 210, and several elastic contacts 230. The female connector body 300 includes a sleeve 310, a core retractor 320, several locking pins 330, and an unlocking magnetic ring 340.

[0035] When the connector 200 mates with the female connector 300, the straight guide groove 210 on the surface of the connector 200 engages with the guide rib 311 on the inner side of the sleeve 310, providing a guiding function so that the connector 200 can be inserted in the correct direction. At the same time, the electrode slip ring 312 on the inner side of the sleeve 310 comes into contact with the elastic contact 230 on the surface of the connector 200, forming a stable electrical connection.

[0036] During the docking process, the locking pin 330, under the action of the second elastic element 332, drives the permanent magnet slider 331 to be pushed out radially and locked into the ring locking groove 220 of the connector 200, thereby realizing the locking and fixing of the connector 200 and the female connector 300.

[0037] When disassembly is required, the unlocking magnetic ring 340 is pushed to slide along the surface of the sleeve 310. Since the unlocking magnetic ring 340 is compatible with the magnetic poles of the permanent magnet slider 331, its magnetic force will pull the permanent magnet slider 331 radially back, causing the locking pin 330 to exit the ring lock groove 220, thereby releasing the lock. At this time, the ejector core 320, under the elastic recovery action of the first elastic element 321, pushes the joint 200 to quickly disengage. Further, one end of the ejector core 320 moves to the same plane as the end of the sleeve 310, achieving sealing of the end of the sleeve 310 and preventing foreign objects from entering.
