The welding tool for industrial robot manufacturing according to claim 1, characterized in that: the traverse assembly includes a drive motor (19) fixedly installed on one side of the drive block (18), and the drive motor (19) One end of the output shaft runs through one side of the drive block (18) and extends to the inside of the drive block (18), and one end of the output shaft of the drive motor (19) is fixedly mounted with a screw (20), and the outside of the screw (20) A threaded block (21) is threaded, the top of the threaded block (21) is slidingly connected to the top inner wall of the drive block (18), the bottom of the threaded block (21) is fixedly installed with a vertical rod, and the bottom of the vertical rod Through the bottom inner wall of the driving block (18) and extending to the bottom of the driving block (18), the bottom of the vertical bar and the top of the mounting seat (22) are fixedly installed;

Adjust the position of the welding head (30) according to the position of the industrial robot material to be welded, first adjust the X-axis direction of the welding head (30), press the switch of the drive motor (19), so that the screw (20) follows the drive motor (19 ) the output shaft rotates, when the screw (20) rotates, because the screw (20) and the threaded block (21) are threaded, according to the characteristics of the threaded connection, another purpose of setting the threaded connection here is to be able to lock at any position, There is no need to set up additional locking parts, which reduces the difficulty and cost of production and improves the implementability. The rotation of the screw (20) can be converted into the movement of the threaded block (21) along the X-axis direction, so that the two welding heads can be adjusted Adjust the X-axis orientation of (30), the X-axis orientation can be limited by the length direction of the positioning plate (14), adjust the Y-axis direction of the two welding heads (30) to the Y-axis of the welding position of the industrial robot material On the same horizontal line, adjust the Y-axis orientation of the two welding heads (30), and the Y-axis orientation can be limited according to the width direction of the positioning plate (14).
A welding tool for industrial robot manufacturing according to claim 1, characterized in that: the power assembly includes an electric push rod (23) fixedly installed on the inner wall of the top of the mounting base (22), and the electric push rod ( 23) A straight plate (24) is fixedly installed on the bottom of the output shaft, and two symmetrically arranged racks (26) are fixedly installed on the bottom of the straight plate (24), and the inner walls on both sides of the mounting seat (22) rotate Screw rods (27) are installed, and the ends of the two screw rods (27) that are close to each other respectively pass through the sides of the two drive plates (29) that are far away from each other and extend to the sides of the two drive plates (29) that are close to each other. And the outer sides of two screw mandrels (27) are threadedly connected with two drive plates (29) respectively, and the outer sides of two screw mandrels (27) are all fixedly sleeved with gears (28), and two gears (28) are respectively connected with two two racks (26) are meshed;

Press the switch of the electric push rod (23) to make the straight plate (24) drive the two racks (26) to move longitudinally. Since the two racks (26) and the two gears (28) are meshed, the rack 26 is set The purpose of driving the gear 28 to rotate is to control the extension distance of the electric push rod 23 to control the number of turns of the gear 28, and then to accurately control the moving distance of the screw mandrel 27 to improve accuracy and reliability. The rack ( 26) The longitudinal movement is converted into the rotation of two gears (28) and two screw mandrels (27). 29) Threaded connection, according to the characteristics of threaded connection, the rotation of the screw rod (27) can be converted into the lateral movement of the drive plate (29), and the two drive plates (29) can drive the two welding heads (30) to each other The side close to or away from each other is moved, and the two welding heads (30) are moved to the position directly above the position where the material of the industrial robot is to be welded, and the rodless cylinder (16) and the welding head (30) are used for welding work.
The welding tool for industrial robot manufacturing according to claim 1, characterized in that: two symmetrically arranged limiting columns (25) are fixedly installed on the top inner wall of the mounting seat (22), and the two limiting columns The bottom of the column (25) runs through the top of the straight plate (24) and extends to the bottom of the straight plate (24), and the outer sides of the two limiting columns (25) are slidingly connected with the straight plate (24), and the two driving plates (29 ) are all slidingly connected to the top of the mount (22).
