[0002] Welding is a common processing step. Traditional welding is generally done manually, which not only greatly increases the labor intensity of workers but also results in low welding efficiency. Furthermore, due to human error, it is difficult to guarantee the quality of the weld. Automatic welding machines are devices that can improve welding efficiency. They are based on motor control, microcontroller control, and PLC control, as shown in CN202223169627.9. Although they can improve welding efficiency, they work by using a turntable in conjunction with a valve body, latches, and a motor. This makes their structure relatively complex, unable to achieve manual control, and difficult to guarantee the stability of the welding operation, thus affecting their applicability to some extent.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] See Figures 1 to 5 As shown, a novel welding machine tool includes a machine tool platform 1 and a laser welding manual robotic arm 2 mounted on the machine tool platform. In this embodiment, the machine tool platform is a conventional structure of the prior art, mainly used for placing workpieces.

[0019] In this embodiment, the laser welding manual robotic arm includes a base 21, a horizontal slider 22, a vertical slider 23, a welding torch fixing bracket 24, a positioner assembly 25, a cam motion mechanical handle assembly 26, and a welding torch body 27. In actual application, the above structures are all metal structural parts, while the welding torch body is a conventional structure of the prior art, which is simply applied and therefore not described in detail. During assembly, the base is positioned at the edge of the machine tool platform; the transverse slider is slidably mounted on the top surface of the base, and the longitudinal slider is slidably mounted on the top surface of the transverse slider; the welding torch mounting bracket is positioned above the longitudinal slider, and the welding torch body is fixed to one end of the welding torch mounting bracket; the cam motion mechanical handle assembly is fixed to the side of the base with screws and can control the translation of the transverse slider; the positioner assembly is fixed to the side of the base with screws, and the positioner assembly and the welding torch body are in the same direction as the base. In use, the cam motion mechanical handle assembly drives the transverse slider to translate on the base and also drives the longitudinal slider to translate longitudinally, improving the stability and effectiveness of the connection, facilitating manual control, and enabling welding operations through the welding torch body. The positioner assembly, in conjunction with the welding torch body, achieves positioning, improving welding accuracy and broad applicability.

[0020] In this embodiment, the base has two upwardly fixed motion guide posts 3; the transverse slider has two parallel waist-shaped grooves 4, and the longitudinal slider has two parallel arc-shaped grooves 5; during assembly, the upper part of the motion guide posts passes through the waist-shaped grooves and arc-shaped grooves; in this embodiment, the waist-shaped grooves and arc-shaped grooves have the same direction, and the length of the waist-shaped groove matches the straight length of the two ends of the arc-shaped groove. The transverse slider moves and is guided and limited by the motion guide posts, and the motion guide posts move within the arc-shaped grooves, driving the longitudinal slider to move. The motion guide posts are used for direction and positioning, ensuring the effectiveness of the transverse slider's transverse translation. Since the transverse slider moves while its motion guide posts move within the waist-shaped grooves, and the transverse slider drives the longitudinal slider to move laterally synchronously, the motion guide posts will move within the arc-shaped grooves, thus causing the longitudinal slider to move a small distance relative to the transverse slider.

[0021] In this embodiment, a transverse slider pressure plate 6 is fixed to the symmetrical edge of the top surface of the base by screws, and a transverse sliding groove 7 is provided between the transverse slider pressure plate and the top surface of the base; the transverse slider is disposed on the base and its symmetrical edge slides within the transverse sliding groove. A longitudinal slider pressure plate 8 is fixed to the symmetrical edge of the top surface of the transverse slider by screws, and a longitudinal sliding groove 9 is provided between the longitudinal slider pressure plate and the top surface of the transverse slider, the longitudinal sliding groove being perpendicular to the transverse sliding groove; the longitudinal slider is disposed on the top surface of the transverse slider and its symmetrical edge slides within the longitudinal sliding groove. This structure improves assembly convenience while ensuring the effectiveness and reliability of the sliding of the transverse and longitudinal sliders.

[0022] In this embodiment, the cam motion mechanical handle assembly includes a mounting base 261, a cam 262, a shaft 263, and a handle 264. During assembly, the mounting base is fixed to the side of the base by screws. The cam is rotatably connected to the top surface of the mounting base via the shaft, and the edge of the cam abuts against the end of the transverse slider. The handle is fixed to the side wall of the cam, and the handle drives the cam to rotate, causing the transverse slider to translate by the pressure of the cam. The size of the cam can be machined and set as needed, specifically to match the length of the waist-shaped groove. The rotation of the cam abuts against the end face of the transverse slider, driving the transverse slider to translate, ensuring the effectiveness of the transverse translation.

[0023] To facilitate resetting, a limiting plate 10 is fixed to the end of the transverse slider pressure plate with screws. The limiting plate and the cam are located on the symmetrical edge of the transverse slider. A reset spring 11 is fixed between the limiting plate and the transverse slider. In use, the cam drives the transverse slider to translate and compress the reset spring, thus resetting the cam. The transverse slider is then reset under the action of the reset spring. This ensures the effectiveness and reliability of the translation and resetting of the transverse slider.

[0024] In this embodiment, the end face of the transverse slider has a spring hole 12, and the end of the return spring is inserted into the spring hole for limiting. This can improve the installation stability and reliability of the return spring.

[0025] In practical applications, the positioner assembly includes a positioning arm 251, a positioner seat 252 rotatably connected to the end of the positioning arm by bolts 254, and a positioner body 253 fixed on the positioner seat. During assembly, the positioning arm is fixed to the side of the base by screws, and the positioner seat rotates up and down around the bolt. This can meet the needs of different applications, and when used with the welding torch body, it can improve the welding accuracy. In this embodiment, the length of the positioning arm can be set as needed, and the positioner body is a conventional structure of the prior art, mainly used for positioning. Its position matches the position of the welding torch body to ensure the accuracy of the welding point.

[0026] In practical applications, a support pad 13 is provided between the welding torch fixing bracket and the top surface of the longitudinal slider, and the welding torch fixing bracket, the support pad, and the longitudinal slider are fixed by screws. This allows for the installation of welding torch fixing brackets of different heights as needed, improving their stability and effectiveness, and also expanding their applicability.

[0027] In this embodiment, a strong magnetic fixing block 14 is fixed to the bottom surface of the base with screws; the base is magnetically positioned at the edge of the machine tool platform by the strong magnetic fixing block. The strong magnetic fixing block is a conventional structure in the prior art, simply applied. This structure facilitates the adjustment of the base structure's position and meets usage requirements, making operation more convenient and practical.

[0028] This utility model has positive effects: The structure of this utility model is reasonably designed, and it is equipped with a horizontal slider, a vertical slider, a welding torch fixing bracket, a positioner assembly, a cam motion mechanical handle assembly, and a welding torch body. The horizontal slider can be driven to move horizontally through the cam motion mechanical handle assembly, and the vertical slider can be driven to move vertically. Welding and positioning are achieved through the welding torch body and the positioner assembly, which improves the convenience of operation, the effectiveness and accuracy of welding, facilitates manual operation and control, is stable and reliable in use, and has strong applicability.

[0029] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0030] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
