DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses an arc welding machine with adjustable welding head angle, referring to Figure 1-Figure 4 , including a frame 1, a support base 2 is fixedly installed on the upper end of the frame 1, an arc welding machine body 3 is fixedly connected to the top of the support base 2, a connecting line 4 is connected to the front surface of the arc welding machine body 3, the other end of the connecting line 4 is connected to a welding head 5, a connecting block 6 is fixedly connected to the upper end of the welding head 5, both ends of the connecting block 6 are fixedly connected to a rotating rod 7, one end of the rotating rod 7 is rotatably connected to a concave seat 8, the other end of the rotating rod 7 passes through the concave seat 8 and is fixedly connected to a brake worm gear 9, when the brake worm gear 9 rotates, the connecting block 6 can be driven to rotate inside the concave seat 8 through the rotating rod 7, so that the operator can easily change the welding position according to specific needs. The angle of the joint 5 is adapted to different welding tasks and enhances applicability. A groove 10 is provided on one side of the bottom of the concave seat 8. A worm 11 is rotatably connected to the inner end of the groove 10. The upper end of the worm 11 is meshedly connected to the bottom of the brake worm gear 9. Under the meshing action, the rotation of the worm 11 synchronously drives the brake worm gear 9 to rotate, and the structure is self-locking, which can prevent the welding head 5 from accidentally moving or changing during work, providing a more stable and reliable welding effect. The outer end of the worm 11 passes through the groove 10 and is fixed with a handwheel 12, which can drive the worm 11 inside the groove 10 to rotate.

[0023] Reference Figure 2-Figure 3 The upper end of the support seat 2 is fixedly connected to a fixed seat 13, and a hydraulic cylinder 14 is installed on the top of the fixed seat 13. The output end of the hydraulic cylinder 14 passes through the upper end of the fixed seat 13 and is connected to a movable block 16. The hydraulic cylinder 14 can accurately control the lifting and lowering of the concave seat 8, thereby adjusting the position of the welding head 5 in the vertical direction to adapt to workpieces of different thicknesses and heights, and at the same time allow the welding head 5 to easily reach the position where welding is required. Two guide columns 15 are fixedly connected to the inner side of the fixed seat 13, and the outer surfaces of the two guide columns 15 are movably connected to the two ends of the movable block 16 respectively. By setting two guide columns 15, the positioning accuracy of the movable block 16 when it moves up and down is more accurate, ensuring stability.

[0024] Reference Figure 3 An L-shaped mounting plate 17 is fixedly connected to the front surface of the movable block 16, and a rotating motor 18 is installed on the upper end of the L-shaped mounting plate 17. The output end of the rotating motor 18 passes through the bottom of the L-shaped mounting plate 17 and is connected to the concave seat 8. By arranging the rotating motor 18 at the upper end of the concave seat 8, the rotating motor 18 can drive the concave seat 8 to rotate and adjust a certain angle when the rotating motor 18 is started, further increasing the angle adjustment range of the welding head 5, and making the adjustment more convenient, saving adjustment time and manpower.

[0025] The implementation principle of an arc welding machine with an adjustable welding head angle in the embodiment of the present application is as follows: when using the device, first place the workpiece to be welded at the bottom of the frame 1, then start the hydraulic cylinder 14 to drive the movable block 16 to move downward on the inner side of the fixed seat 13, so that the welding head 5 on the inner side of the concave seat 8 moves downward, and then start the arc welding machine body 3 to drive the welding head 5 to weld the workpiece. When the angle needs to be adjusted, the handwheel 12 on the side of the concave seat 8 is driven by the handwheel 12 to drive the worm 11 inside the groove 10 to rotate. Through the cooperation of the worm 11 and the brake worm gear 9, the angle of the welding head 5 changes, and the rotating motor 18 drives the concave seat 8 to rotate, so that the workpiece can be welded at multiple angles.
