DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

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

[0019] In this embodiment, the laser welding manual robot arm includes a base 21, a transverse slider 22, a longitudinal slider 23, a welding gun fixing bracket 24, a positioner assembly 25, a cam motion mechanical handle assembly 26, and a welding gun body 27. In actual application, the above structures are all metal structural parts, and the welding gun body is a conventional structure of the prior art. It is only used for simple application and is not described in detail. During assembly, the base is arranged at the edge of the machine tool platform; the transverse slider can be arranged on the top surface of the base for transverse sliding movement, and the longitudinal slider can be arranged on the top surface of the transverse slider for longitudinal sliding movement; and the welding gun fixing bracket is arranged above the longitudinal slider, and the welding gun body is fixed on one end of the welding gun fixing bracket; the cam motion mechanical handle assembly is fixed to the side of the base by screws and can control the translation of the transverse slider; the positioner assembly is fixed to the side of the base by screws, and the positioner assembly and the welding gun body are in the same direction of the base. During use, the cam motion mechanical handle assembly drives the transverse slider to translate on the base, and drives the longitudinal slider to translate longitudinally, thereby improving the stability and effectiveness of the connection, facilitating manual control operation, and realizing welding operation through the welding gun body, and cooperating with the positioner assembly to realize positioning, which can improve the welding accuracy and has strong applicability.

[0020] In this embodiment, two motion guide posts 3 are fixed to the upper side of the base; two parallel waist-shaped grooves 4 are provided on the transverse slider, and two parallel arc-shaped grooves 5 are provided on the longitudinal slider; during assembly, the upper portion of the motion guide post is inserted into the waist-shaped groove and the arc-shaped groove; in this embodiment, the waist-shaped groove and the arc-shaped groove 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 in the arc-shaped groove to drive the longitudinal slider to move in the translation. The motion guide posts are used to limit the direction and position, ensuring the effectiveness of the transverse slider's transverse translation. Since the transverse slider translates, its operating guide posts translate in the waist-shaped groove, and the transverse slider drives the longitudinal slider to move in the transverse direction synchronously, the motion guide posts will translate in the arc-shaped groove, thereby causing the longitudinal slider to translate a small distance relative to the transverse slider.

[0021] In this embodiment, a transverse slider pressure plate 6 is fixed to the symmetrical edges of the top surface of the base via 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 mounted on the base and its symmetrical edges slide within the transverse sliding groove. A longitudinal slider pressure plate 8 is fixed to the symmetrical edges of the top surface of the transverse slider via screws, and a longitudinal sliding groove 9 is provided between the longitudinal sliding pressure plate and the top surface of the transverse slider. The longitudinal sliding groove is perpendicular to the transverse sliding groove. The longitudinal slider is mounted on the top surface of the transverse slider and its symmetrical edges slide within the longitudinal sliding groove. This structure improves assembly convenience while also 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, and the cam is rotatably connected to the top surface of the mounting base via the shaft, with the edge of the cam abutting the end of the transverse slider. The handle is fixed to the side wall of the cam, driving the cam to rotate, and the cam presses to cause the transverse slider to translate. The size of the cam can be customized, specifically to match the length of the kidney-shaped groove. The cam rotates to press against the end surface of the transverse slider, driving the transverse slider to translate, ensuring the effectiveness of the transverse translation.

[0023] To facilitate resetting, a limit plate 10 is fixed to the end of the transverse slider's pressure plate via screws. The limit plate and the cam are located on symmetrical edges of the transverse slider. A return spring 11 is fixed between the limit plate and the transverse slider. During use, the cam drives the transverse slider to translate and compresses the return spring, causing the cam to reset, and the transverse slider to reset under the action of the return spring. This ensures the effectiveness and reliability of the transverse slider's translation and resetting.

[0024] In this embodiment, the end surface of the transverse slider is provided with a spring hole 12, and the end of the reset spring is inserted into the spring hole for limiting position, which can improve the installation stability and reliability of the reset spring.

[0025] In actual use, the locator assembly includes a locator arm 251, a locator seat 252 rotatably connected to the end of the locator arm via a bolt 254, and a locator body 253 fixed to the locator seat. During assembly, the locator arm is fixed to the side of the base via screws, and the locator seat rotates up and down around the bolts. This can meet the needs of different situations and, in conjunction with the welding gun body, can improve welding accuracy. In this embodiment, the length of the locator arm can be adjusted as needed. The locator body is a conventional structure in the prior art, primarily used for positioning. Its position coordinates with that of the welding gun body to ensure the accuracy of the weld point.

[0026] In actual use, a support pad 13 is provided between the welding gun mounting bracket and the top surface of the longitudinal slider, and the welding gun mounting bracket, support pad, and longitudinal slider are fixed together by screws. This allows the welding gun mounting bracket to be installed at different heights as needed, improving its stability and effectiveness, while also expanding its applicability.

[0027] In this embodiment, a strong magnetic fixing block 14 is fixed to the bottom surface of the base via 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 and is simply applied. This structure facilitates the position adjustment of the base structure and usage requirements, making operation more convenient and practical.

[0028] The present invention has positive effects: the structure of the present invention is reasonably set up, and it is provided with a transverse slider, a longitudinal slider, a welding gun fixing bracket, a positioner assembly, a cam motion mechanical handle assembly and a welding gun body.
