Description

Technical Field

[0001] This utility model relates to a push-pull wire welding robot torch, belonging to the technical field of push-pull wire welding robot torches. Background Technology

[0002] The wire feeding mechanism of the push-pull wire welding robot is mounted on the welding torch and uses welding wire for welding. The diameter of the welding wire is generally 1.0-1.6mm. The wire feeding mechanism includes a pair of wire feeding rollers and a wire pressing roller, and the wire feeding rollers are driven by a motor.

[0003] Existing push-pull wire welding robots suffer from severe overheating of the wire feeding wheel drive motor, affecting production stability. Furthermore, the installation position of the wire feeding wheel is generally not easy to observe, making it difficult to detect wear in a timely manner. Replacing the wire feeding wheel is also inconvenient, impacting production efficiency. Utility Model Content

[0004] This utility model proposes a push-pull wire welding gun for robots, which aims to overcome the above-mentioned shortcomings of the existing technology, improve the heating of the wire feeding wheel drive motor, and improve the convenience of observing and replacing the wire feeding wheel.

[0005] The technical solution of this utility model is a push-pull wire welding gun for robots. Its structure includes a gun head bend, a wire feeding mechanism, and a collision avoidance device connected in sequence. The wire feeding mechanism includes a wire feeding wheel and a wire pressing wheel mounted adjacent to each other on the main body. The welding wire passes between the wire feeding wheel and the wire pressing wheel. The wire feeding wheel is mounted on the drive end of a drive motor, which is located at the bottom of the main body. Water-passing blocks are located on both sides of the drive motor, with the top of the water-passing blocks connected to the bottom of the main body. Cooling water channels are connected between the main body and the water-passing blocks. A thermally conductive silicone pad is placed between the drive motor and the water-passing blocks. When the welding gun is working, the heat from the drive motor is transferred to the water-passing blocks through the thermally conductive silicone pad. Because water flows within the water-passing blocks, most of the heat from the drive motor is carried away, ensuring the normal operation of the drive motor.

[0006] Preferably, the main body is made of copper, and the water-passing block is made of red copper. The thermally conductive silicone sheet enables both thermal conductivity and insulation between the water-passing block and the drive motor. Red copper dissipates heat quickly, effectively carrying away most of the heat from the drive motor.

[0007] Preferably, the main body, drive motor, and water-conducting block are all covered by an outer shell, with an openable dust cover on the top of the shell. The wire feeding wheel and pressure wheel are covered inside the dust cover. This facilitates observation of the wire feeding wheel's operation and provides more operating space for replacing the wire feeding wheel.

[0008] Preferably, insulating components are provided between the wire feeding wheel, the drive motor drive shaft, and the main body, as well as between the wire pressing wheel and the main body. This ensures insulation between the wire feeding wheel and the drive motor and the main body, and between the wire pressing wheel and the main body.

[0009] The advantages of this utility model are: reasonable structural design, cooling water channels on both sides of the main copper body and drive motor, and thermal conductive silicone pads, which can effectively improve the heat generation of the drive motor and ensure normal operation of the motor. A flip-up dust cover is provided at the wire feeding mechanism to facilitate the observation and replacement of the wire feeding wheel and improve production efficiency. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0018] like Figure 1-5 As shown, a push-pull wire welding robot torch has a structure including a torch head bend tube 1, a wire feeding mechanism 2 and a collision avoidance device 3 connected in sequence. The welding wire 4 passes from the outer end of the inner axial center of the collision avoidance device 3, through the inner axial center of the collision avoidance device 3, the wire feeding mechanism 2 and the inner axial center of the torch head bend tube 1 and extends to the outer end of the inner axial center of the torch head bend tube 1.

[0019] The wire feeding mechanism 2 includes a wire feeding wheel 24 and a wire pressing wheel 25 mounted on the main body 21 and arranged adjacent to each other. The welding wire 4 passes between the wire feeding wheel 24 and the wire pressing wheel 25. The wire feeding wheel 24 is mounted on the driving end of the drive motor 26. The drive motor 26 is located at the bottom of the main body 21. Water passage blocks 211 are provided on both sides of the drive motor 26. The top of the water passage blocks 211 is connected to the bottom of the main body 21. The main body 21 and the water passage blocks 211 are provided with interconnected cooling water channels. A thermally conductive silicone sheet 27 is provided between the drive motor 26 and the water passage blocks 211. The main body 21, the drive motor 26, and the water passage blocks 211 are covered by an outer shell 23. The top of the outer shell 23 is provided with an openable dust cover 22. The wire feeding wheel 24 and the wire pressing wheel 25 are covered inside the dust cover 22.

[0020] In the specific design, the main body 21 is made of copper, the water-passing block 211 is made of red copper, and the thermally conductive silicone sheet 27 enables heat conduction and insulation between the water-passing block 211 and the drive motor 26. When the welding torch is working, the heat generated by the drive motor 26 is transferred to the water-passing block 211 through the thermally conductive silicone sheet 27. Since water flows in the water-passing block 211 and red copper dissipates heat quickly, it can effectively remove most of the heat from the drive motor 26, ensuring the normal operation of the drive motor 26.

[0021] The dust cover 22 is preferably 180° rotatable, which makes it easy to observe the operation of the wire feeding wheel 24 and provides more operating space for replacing the wire feeding wheel 24.

[0022] Insulating components 28 are provided between the wire feeding wheel 24, the drive shaft of the drive motor 26 and the main body 21, and between the wire pressing wheel 25 and the main body 21, to ensure insulation between the wire feeding wheel 24 and the drive motor 26, the main body 21, and between the wire pressing wheel 25 and the main body 21.

[0023] like Figure 6 As shown in the preferred embodiment, buttons can be installed on the outer casing 23 below the anti-collision device 3, and an external synchronizer with a display screen can be installed. The display screen can display information such as wire feeding motor voltage, current, torque, and fault codes, and provide a parameter setting interface. The buttons can correspond to operations such as wire feeding, wire retraction, and fault handling. The buttons can also have indicator lights to show the working status. The synchronizer can be configured with buttons to adjust parameters. The synchronizer should be equipped with an interface for connecting the welding torch, wire feeder, and digital communication. The above functions can be implemented according to production needs and combined with existing technology, and are not within the protection scope of this utility model.

[0024] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
