Description

Technical Field

[0001] This utility model relates to the field of welding torch technology, and in particular to a quick-release push-pull welding torch. Background Technology

[0002] A welding torch, also known as a welding gun, is one of the main pieces of equipment in hot air welding. It consists of a heating element, nozzle, and other components. Based on its structure, it can be categorized into gas welding torches, electric welding torches, high-speed welding torches, push-pull welding torches, and automatic welding torches. Currently, with increasing production demands, many factories are using robots to replace manual welding processes on their assembly lines. A welding torch robot is an automated welding device, typically composed of a robotic arm, a welding torch, a control system, and sensing devices. It performs welding operations at fixed positions according to a pre-set program, achieving high welding precision. It also effectively prevents the harmful gases produced during welding from affecting the human body and can operate continuously for extended periods, significantly increasing production output. However, due to the long working hours and repetitive processing of the welding torch robot, the lifespan of the welding torch installed on it is extremely short. Under normal use, the welding torch and its consumable parts (such as the nozzle) installed on the welding torch robot can only be used for about a week, requiring frequent maintenance and replacement. A common replacement method is to detach the welding torch and its mounting base entirely from the welding torch robot. For example, Chinese patent document CN202321531624.7 discloses a quick-release connector for a welding torch holder, including a quick-release base with a quick-release through hole on its outer surface, a connecting plate fixedly connected to its side surface, a screw hole on the outer surface of the connecting plate, an adjusting base fixedly connected to the side surface of the connecting plate, and an adjusting component fixedly connected to the side surface of the connecting base; a bracket with a movable component fixedly connected to its upper end, a movable rod rotatably connected to one side of the movable component, a welding torch holder detachably connected to the outer surface of the movable rod, and a welding torch fixedly connected inside the welding torch holder. This patent makes disassembly and assembly more convenient and faster by using a quick-release connection between the quick-release base and the equipment. However, the quick-release method, which only uses through holes and bolt holes for threaded connections, has low installation accuracy. Each installation and maintenance requires operators to reposition the torch, making the installation process complicated and labor-intensive.

[0003] Therefore, it is necessary for those skilled in the art to provide a quick-release push-pull welding torch to improve the ease of disassembly and installation accuracy of the welding torch on the welding torch robot, thereby improving the performance and reducing production costs. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-release push-pull welding torch to solve the technical problems of low service life, low installation accuracy, and the need for operators to reposition the torch every time it is installed and maintained, which are complicated and labor-intensive.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a quick-release push-pull welding torch, including a mounting base and a welding torch body detachably mounted on the mounting base. A boss is provided on one side of the mounting base, and a mounting groove is provided inward on the end face of the boss. Multiple locking holes are provided inward on the circumferential side of the boss. The locking holes pass through the mounting groove and extend into the boss. The axis of the locking holes is evenly distributed around the axis of the boss in the circumferential direction. At the same time, the multiple locking holes are evenly distributed in a triangular shape around the outside of the mounting groove. A fixing member is detachably connected in the locking hole. The fixing member is threaded to the wall of the boss. A connecting member is provided at the end of the welding torch body. The connecting member is fitted and connected in the mounting groove. The fixing member penetrates the wall of the connecting member.

[0006] Furthermore, the connector includes a welding torch connection part and a plug-in connection part. The welding torch connection part is installed on the welding torch body, and the plug-in connection part is plugged into the mounting groove. One end of the plug-in connection part located in the mounting groove is provided with a mounting hole, and one end of the fastener passes through the mounting hole and is threaded into the wall of the boss.

[0007] Furthermore, the plug-in connection has a protrusion on the side facing the mounting groove. The protrusion is polyhedral in shape, and a locking part is protruding on the side of the protrusion. The locking part is plate-shaped and is symmetrically arranged on the protrusion.

[0008] Furthermore, the locking part is provided with multiple parts and is evenly arranged around the axial direction of the plug-in connection part. The mounting hole is provided on the locking part, and one end of the fastener passes through the locking part and is threaded to the wall of the boss.

[0009] Furthermore, the mounting groove includes a first insertion part and a second insertion part, and the locking hole extends inward from the circumference of the boss and passes through the second insertion part. The cross-section of the first insertion part is consistent with the cross-sectional profile of the protrusion, and the cross-section of the second insertion part is consistent with the cross-sectional profile of the locking part.

[0010] Furthermore, the fastener is a bolt, with one end abutting against the outer circumferential surface of the boss, and the other end of the fastener being inserted into the locking hole and extending into the mounting groove.

[0011] Furthermore, the locking hole includes a groove and a screw hole. The screw head of the fastener abuts against the bottom wall of the groove of the locking hole. The threaded part of the fastener is fitted into the screw hole of the locking hole, and the threaded part of the fastener is threadedly connected to the screw hole of the locking hole. The screw hole of the locking hole penetrates the mounting groove.

[0012] The beneficial effects of this utility model are as follows: By increasing the number of locking parts at the locking section and adopting a uniform distribution, this utility model ensures that after the connector is inserted into the mounting groove, the protruding part can connect to the first insertion part, and the locking part can connect to the second insertion part, thereby guaranteeing the accuracy of the connection. Simultaneously, the increased number of connection points effectively prevents inaccurate positioning caused by structural wear. When replacing the welding torch, simply insert the connector directly into the mounting groove according to the outer contour of the insertion part to achieve accurate positioning, eliminating the need for repeated positioning and improving maintenance convenience. Furthermore, compared to the single locking connection in existing technologies, this utility model maximizes the number of fixing parts at the locking section, ensuring the stability of the welding torch installation and making the connection more uniform and stable.

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] Please see Figure 1 This utility model provides a quick-release push-pull welding torch, including a mounting base 10 and a welding torch body 20 detachably mounted on the mounting base 10. The mounting base 10 is detachably connected to a robotic arm using fasteners such as bolts or screws. The robotic arm is a common welding gun robot on the market. The welding gun robot is used to control the rotation of the welding torch body 20 in all directions.

[0024] Further, please refer to Figures 2-5 The mounting base 10 is disc-shaped, and a boss 12 is protruding on one side of the mounting base 10. A mounting groove 13 is opened inward on the end face of the boss 12. A plurality of locking holes 15 are opened inward on the circumferential side of the boss 12. The locking holes 15 pass through the mounting groove 13 and extend into the boss 12. A fastener 14 is detachably connected in the locking hole 15. The fastener 14 includes, but is not limited to, bolts.

[0025] In this embodiment, the locking hole 15 includes a groove and a screw hole. The screw head of the fastener 14 abuts against the bottom wall of the groove of the locking hole 15. The threaded part of the fastener 14 is connected to the screw hole of the locking hole 15, and the threaded part of the fastener 14 is threadedly connected to the screw hole of the locking hole 15.

[0026] The screw hole of the locking hole 15 passes through the mounting groove 13. The end of the welding torch body 20 is provided with a connector 21. The connector 21 is fitted and connected in the mounting groove 13 and connected by the fastener 14.

[0027] Specifically, the connector 21 includes a welding torch connecting part 211 and a plug-in connecting part 212. The welding torch connecting part 211 is mounted on the welding torch body 20, and the plug-in connecting part 212 is plugged into the mounting groove 13. One end of the plug-in connecting part 212 located in the mounting groove 13 has a mounting hole 215. The threaded portion of the fixing member 14 passes through the mounting hole 215 and is threaded into the locking hole 15. This ensures that the connector 21 can be stably connected to the boss 12. When the welding torch body 20 needs to be replaced, only the fixing member 14 needs to be removed to directly replace the welding torch body 20, improving the convenience of replacement.

[0028] In this embodiment, the mounting hole 215 is a through hole, and the diameter of the mounting hole 215 is the same as the outer diameter of the threaded part of the fastener 14. This ensures that after the fastener 14 is connected to the mounting hole 215, the fastener 14 will abut against the mounting hole 215, providing a certain support effect for the plug-in connection part 212.

[0029] In another embodiment, the mounting hole 215 is a threaded hole, and the fastener 14 is threadedly connected to the mounting hole 215, thereby ensuring the contact area between the fastener 14 and the mounting hole 215 and ensuring the stability of the connection.

[0030] Please see Figure 5 , Figure 8 In this embodiment, the plug-in connection 212 has a protrusion 214 on the side facing the mounting groove 13. The protrusion 214 is polyhedral in shape, and a locking part 213 is protruding on the side of the protrusion 214. The locking part 213 is plate-shaped and has multiple locking parts evenly arranged around the axis of the plug-in connection 212. The mounting hole 215 is provided on the locking part 213, and one end of the fastener 14 passes through the locking part 213 and is threaded into the locking hole 15.

[0031] The mounting groove 13 includes a first insertion / removal portion 131 and a second insertion / removal portion 132. The locking hole 15 extends inward from the circumferential surface of the boss 12 and passes through the second insertion / removal portion 132. The cross-section of the first insertion / removal portion 131 is consistent with the cross-sectional profile of the protrusion 214, and the cross-section of the second insertion / removal portion 132 is consistent with the cross-sectional profile of the locking portion 213.

[0032] This invention increases the number of locking parts at the locking part 213 and adopts a uniform distribution method, so that after the connector 21 is inserted into the mounting groove 13, the protrusion 214 can be connected to the first insertion part 131, and the locking part 213 can be connected to the second insertion part 132, thereby ensuring the accuracy of the connection. At the same time, the more connection parts can effectively prevent the problem of inaccurate positioning caused by structural wear. When replacing the welding torch body 20, the connector 21 can be directly inserted into the mounting groove 13 according to the outer contour of the insertion connection part 212 to achieve accurate positioning without the need for repeated positioning, thus improving the convenience of maintenance.

[0033] In this embodiment, the locking part 213 is symmetrically arranged on the protrusion 214, which ensures stable connection while facilitating insertion and removal by the operator.

[0034] In this embodiment, the axes of the locking holes 15 are evenly distributed around the circumference of the axis of the boss 12. Multiple locking holes 15 are triangularly distributed evenly around the outside of the locking part 213. This maximizes the number of fixing parts 14 while ensuring connection stability, thus guaranteeing the installation stability of the welding torch body 20. Compared to a single locking connection, the connection of this invention is more uniform and more stable.

[0035] The mounting base 10 is provided with a plurality of through holes 11 evenly distributed, and fasteners such as connecting bolts or screws are fitted into the through holes 11 for mounting the mounting base 10 onto the welding gun robot.

[0036] The specific operation method of this utility model is as follows: Connector 21 is plugged into the mounting groove 13, and fastener 14 is threaded into the locking hole 15, thus fixing connector 21 into the boss 12. Finally, mounting base 10 is installed onto the welding torch robot to complete the installation. For replacement, fastener 14 located in the locking hole 15 is removed, allowing for quick replacement of the welding torch body 20 and connector 21.

[0037] This invention increases the number of locking parts at the locking portion 213 and adopts a uniform distribution method, so that after the connector 21 is inserted into the mounting groove 13, the protrusion 214 can connect to the first insertion / extraction portion 131, and the locking portion 213 can connect to the second insertion / extraction portion 132, thereby ensuring the accuracy of the connection. At the same time, the increased number of connection points effectively prevents inaccurate positioning caused by structural wear. When replacing the welding torch body 20, the connector 21 only needs to be directly inserted into the mounting groove 13 according to the outer contour of the insertion / extraction connection portion 212 to achieve accurate positioning, eliminating the need for repeated positioning and improving maintenance convenience. Furthermore, compared to the single locking connection in the prior art, this invention maximizes the number of fixing parts 14 at the locking portion 213, ensuring the installation stability of the welding torch body 20, making the connection more uniform and stable.
