[0046] Working principle:

[0047] When welding mechanical workpieces:

[0048] Feeding process:

[0049] The workpiece is placed on the upper ends of the right-angle rods 204 and the multiple groups of cross rods 206 on both sides. Under the action of gravity, the workpiece can slide to the surface of the support plate 203, and the fourth motor 210 is controlled to work so that the output shaft of the fourth motor 210 rotates to drive the threaded rod 205 to rotate, so that the threaded rod 205 can drive the counterweight block 202 to slide on the outer walls of the support columns 207 on both sides, so that the counterweight block 202 can move to the side away from the base 1. When the counterweight block 202 moves over the supporting legs 208 on both sides, the weight of the end of the right-angle rods 204 on both sides away from the base 1 will be increased, so that the right-angle rods 204 can move to one side of the counterweight block 202. Tilt, the right-angle rods 204 on both sides can drive the support plate 203 to move upward through the connecting blocks 209 on both sides, and the movement of the support plate 203 can drive the sliders 3 on both sides to move upward synchronously, so that the sliders 3 on both sides can push the slide blocks 5 on both sides to move upward synchronously. When the support plate 203 moves upward, the slides 3 on both sides can have movement space under the action of the slides on the surfaces of the slide blocks 5, so that the slide blocks 5 on both sides can drive the four groups of sleeves 4 to move synchronously, so that the four groups of sleeves 4 can slide on the outer walls of the four groups of slide rods 19, so that the support plate 203 can drive the workpiece to move upward, so that the workpiece can move to the middle of the clamping plates 7 on both sides.

[0050] Welding process:

[0051] The second motor 6 is controlled to work so that the output shaft of the second motor 6 rotates to drive the stud 10 to rotate, so that the stud 10 can drive the clamping plates 7 on both sides to move relative to each other, so that the clamping plates 7 on both sides can clamp the workpiece to fix the position of the workpiece. At the same time, the robot arm base 12, the first section 14 of the robot arm and the second section 13 of the robot arm are controlled to work so that the robot arm can drive the welding gun 11 to move so that the welding gun 11 can weld the workpiece. According to the above operations, the counterweight block 202 returns to its original position, the support plate 203 drops to its original position, and the frame 803 can rotate.

[0052] Adjustment process:

[0053] When the angle of the workpiece needs to be adjusted, the first motor 805 is controlled to work so that the output shaft of the first motor 805 rotates to drive the incomplete gear 801 to rotate, so that the incomplete gear 801 can drive the gear 802 to rotate. When the incomplete gear 801 is no longer engaged with the gear 802, the gear 802 stops rotating. When the gear 802 rotates, it can drive the rotating rod 804 to rotate synchronously. The rotating rod 804 can drive the frame 803 to rotate synchronously, so that the angle of the workpiece can be adjusted.

[0054] Locking process:

[0055] Before adjusting the workpiece, the third motor 905 is controlled to work so that the output shaft of the third motor 905 rotates to drive the reel 906 to rotate slowly, so that the reel 906 can reel the nylon rope 907, and the nylon rope 907 can pull the square rod 904 to move downward, so that the upper end of the square rod 904 is no longer engaged with the sharp gear 908, so that the sharp gear 908 can rotate. While the square rod 904 moves downward, the square rod 904 can compress the spring 902 through the cross plate 901. After adjusting the angle of the workpiece, the third motor 905 is stopped, and the cross plate 901 can be pushed by the spring 902 to move upward quickly, so that the upper end of the square rod 904 can be quickly engaged with the sharp gear 908, so that the angle of the workpiece can be quickly fixed.
