Abstract

This invention discloses a gantry-type high-efficiency laser composite welding machine, comprising a base and a top plate. The top plate is fixedly mounted on the top of the base via a bracket. This invention relates to the field of laser welding technology. This gantry-type high-efficiency laser composite welding machine, by setting a gantry welding mechanism, an intermittent rotating welding mechanism, an intermittent flipping mechanism, and an intermittent material lifting mechanism between the base and the top plate, allows for the coordinated operation of these mechanisms during welding.

Description

Technical Field

[0002] A gantry laser welding machine is a type of laser welding machine that uses a gantry support to move the laser generator along the X, Y, and Z axes for welding.

[0015] Beneficial effects

[0016] This invention provides a gantry-type high-efficiency laser composite welding machine. Compared with existing technologies, it has the following advantages:

At the same time, the auxiliary materials that are butt welded to the plate are lifted at equal distances to avoid excessive bending of the manual to lift the auxiliary materials.

Each is equipped with a mounting box 907. An inclined surface mating block 908 is slidably connected inside the mounting box 907. A third spring 909 is fixedly connected between the inclined surface mating block 908 and the mounting box 907.

Slide rail blocks 916 are slidably connected inside the slide rail grooves 915, and the bottom of the slide rail blocks 916 is fixedly connected to the top of the threaded rings 906.

[0046] The specific steps are as follows:

[0047] Step 1, clamping and feeding: The plate to be welded is fed into the clamping frame 6 in the center, and the plate is clamped and fixed by tightening the fastening screw 17. Then, the auxiliary material to be welded is placed on the plate on the right side for welding.

[0048] During welding, the second servo motor 308 is activated, causing the gantry 302 to move back and forth along the surface of the second threaded rod 309. Then, according to the welding position of the auxiliary material and the plate, the laser welding gun 307 is adjusted left, right and up and down by the drive of the first servo motor 303 and the electric telescopic rod 306.

[0049] Step 2, Material Transfer: As the gantry 302 moves backward, it synchronously drives the push-pull plate 717 to move. During the backward movement, the push-pull plate 717 gradually comes into contact with the bend of the U-shaped frame 716, and simultaneously drags the U-shaped frame 716 backward. The backward movement of the U-shaped frame 716 drives the extrusion rod 705 from the protruding part of the toothed plate 702 to the recessed part, causing the toothed plate 702 to retract into the movable frame 701. The retraction of the toothed plate 702 will disengage it from the first gear 704. The pressing rod 705 moves backward, simultaneously driving the front convex end lifting rod 713 to insert into the first insertion rod 707. The protruding part of the convex end lifting rod 713 presses against the first insertion rod 707, causing the first insertion rod 707 to be pulled out from the first slot 714. This causes the pressing rod 705 to move the movable frame 701 as a whole. When the gantry 302 moves backward and the movable frame 701 slides backward to its limit, the second insertion rod 710 will enter the second slot 715 for limiting.

[0050] Then, the second threaded rod 309 is reversed, causing the gantry 302 to return to its original position. Simultaneously, the gantry 302 drives the push-pull plate 717 to contact the front bend of the U-shaped frame 716, and drives the U-shaped frame 716 and the pressing rod 705 to return to their original positions. The pressing rod 705 moves from the recessed part of the toothed plate 702 to the protruding part, causing the toothed plate 702 to extend pre-exist, waiting to mesh with the first gear 704. When the pressing rod 705 moves to the protruding part of the toothed plate 702, the corresponding… The pressing rod 705 presses and lifts the second insertion rod 710 through the rear convex end lifting rod 713, causing the second insertion rod 710 to be pulled out of the second slot 715. As the pressing rod 705 carries the movable frame 701 and the extended convex and concave tooth plate 702 forward and resets, the convex and concave tooth plate 702 will mesh with the first gear 704, causing the main shaft 4 to drive the turntable 5 to rotate 180 degrees. After the turntable 5 rotates, the corresponding single-sided welded plate moves to the left side, and the unwelded plate on the left side moves to the right side.

[0051] Step 3, Flipping and Welding: When the turntable 5 rotates, it will simultaneously drive the annular plate 801 and the rotating rod 802 to move circumferentially. During the process of the rotating rod 802 moving circumferentially from the left to the right, the pressure roller 811 at the top of the annular plate 801 will contact the inclined surface of the arc-shaped inclined pressure block 813 in advance and be gradually squeezed to the bottom of the arc-shaped inclined pressure block 813. The pressure roller 811 presses down and drives the pressure rod 810 to press the limiting insertion block 807 inside the limiting insertion hole 809, causing the limiting insertion block 807 to retract into the storage sleeve 806. Inside, and disengaging from the limiting insertion hole 809, when the corresponding limiting insertion block 807 disengages from the limiting insertion hole 809, the second gear 805 at the bottom of the rotating rod 802 simultaneously begins to mesh with the arc-shaped internal gear ring 812. As the meshing stroke with the arc-shaped internal gear ring 812 is completed, the second gear 805 will drive the rotating rod 802 to rotate 180 degrees. After the second gear 805 has rotated, it will simultaneously drive another symmetrically arranged limiting insertion block 807 to enter the limiting insertion hole 809 for rotation angle limiting engagement.

[0052] Secondly, the rotation of the rotating rod 802 is synchronized through the meshing of two bevel gears 804, causing the crossbar 803 to drive the clamping frame 6 and the plate inside the clamping frame 6 to flip over. When the plate on the left side is flipped and transferred to the right side, the operator can simultaneously place the auxiliary material on the top of the auxiliary material tray 904 onto the plate according to the welding position and weld it.

[0053] It should be noted that as the device operates continuously, the unwelded side of the plate after welding on one side on the left side will automatically flip over and move to the right side as the plate rotates to the right.

[0054] Step 4, Equidistant Feeding of Auxiliary Materials: When the main shaft 4 rotates intermittently to facilitate the rotation of plates and sequential flipping for welding, the main shaft 4 synchronously rotates the threaded shaft 902 through the transmission cooperation of the pulley 911 and the belt 912. The rotation of the threaded shaft 902 causes the inner threaded cylinder 903 to drive the auxiliary material support plate 904 to be lifted intermittently at equal intervals, thereby gradually raising the auxiliary materials on the top of the auxiliary material support plate 904.
