The side of the nut sleeve 49 is rotatably connected to the third plate-shaped bracket 28, and a position adjustment component 32 for adjusting the angle and height of the welding head 31 is arranged inside the mounting frame 30. The position adjustment component 32 includes a vertical rod 40 slidably connected to the mounting frame 30. The mounting frame 30 is a U-shaped structure with an opening upward. The vertical rod 40 is slidably connected to the left side of the lower end of the mounting frame 30. The lower end of the vertical rod 40 is rotatably connected to the left side of the upper surface of the flip plate 37, and a welding head 31 is arranged on the lower surface of the flip plate 37. A lifting plate 44 arranged in a left-right direction is fixedly connected to the upper end of the vertical rod 40, and a lifting cylinder 41 is arranged on the right side of the lower surface of the lifting plate 44. The lifting cylinder 41 can push the flip plate 37 to rotate around the lower end of the vertical rod 40, thereby realizing the processing of adjusting the inclination angle of the welding head 31. A through hole is set on the right side of the lower end of the mounting frame 30, and the piston rod of the lifting cylinder 41 can pass through the through hole to extend to the bottom of the mounting frame 30, and the piston rod of the lifting cylinder 41 is rotatably connected to the upper end of the connecting rod 39, and the lower end of the connecting rod 39 is rotatably connected to the right side of the upper surface of the flip plate 37, and blocks 38 are set on the left and right sides below the vertical rod 40. When the flip plate 37 contacts the block 38 on the right, the welding head 31 is in a vertical state, and when the flip plate 37 contacts the block 38 on the left, the welding head 31 is tilted toward the lower left, so that the welding head 31 can perform welding processing on different positions of the tool handle piece 45, and a lifting motor 42 is set on the left side of the mounting frame 30, and the output shaft of the lifting motor 42 is fixedly connected to the lower end of the vertically arranged lifting screw rod 43, and the upper part of the lifting screw rod 43 is threadedly connected to the left end of the lifting plate 44, so that the rotation of the lifting screw rod 43 can drive the lifting plate 44 to move up and down, thereby realizing the height adjustment processing of the welding head 31.

[0031] During the implementation of this embodiment, first, under the action of gravity, the blade groove 14 slides to the bottom of the circular guide rail 12 along with the arc slide 13, and the clamping cylinder 20 is started, the two handle clamping blocks 18 are separated from each other, and the blade body 46 to be welded is inserted from top to bottom from the notch above the circular guide rail 12, the left end of the blade body 46 is inserted into the interior of the U-shaped clamping head 9, and the blade part of the blade body 46 falls into the blade groove 14, and the two matching handle pieces 45 are respectively placed on the sides of the front and rear handle clamping blocks 18, and the hollow recessed part of the handle piece 45 is kept facing the center part of the base 1. At this time, the tool component clamping is completed.

[0032] After preliminary fixing, the clamping cylinder 20 is started in reverse, and the two tool handle clamping blocks 18 bring the two tool handle pieces 45 closer to each other. The two tool handle pieces 45 are fitted on the protruding part of the right end of the blade body 46. At this time, the lifting cylinder 41 is started, and the piston rod of the lifting cylinder 41 is contracted, and the flip plate 37 rotates counterclockwise, and the flip plate 37 contacts the block 38 on the right side. The welding head 31 is in a vertical state, and the lifting motor 42 is started. The lifting screw 43 drives the lifting plate 44 to move downward, and the welding head 31 moves to a state at the same height as the upper part of the tool handle piece 45. At this time, the telescopic motor 33 is started, and the welding head 31 moves to the left along with the mounting frame 30. The welding head 31 welds the upper sides of the two tool handle pieces 45. At this time, the preliminary fixing process is completed between the tool handle piece 45 and the blade body 46.

[0033] Annular welding process, when the welding head 31 moves to the position where the left end of the handle piece 45 is connected to the blade body 46, the telescopic motor 33 is stopped, and the flip motor 6 is started at this time. The flip motor 6 drives the U-shaped clamping head 9 to flip. When the U-shaped clamping head 9 completes a 180° flip, for example, viewed from the right side, the blade body 46 rotates 180° clockwise. At this time, the left end of the handle piece 45 originally located on the front side is welded with the blade body 46. At this time, the flip motor 6 drives the blade body 46 to continue rotating 180° again, and the left end of the handle piece 45 on the circular rear side is also welded with the blade body 46, and the blade body 46 and the two handle pieces 45 are fixed.

[0034] To strengthen the welding process, the welding head 31 is turned off, and the flip motor 6 is started again. The blade body 46 is flipped 180 degrees again. At this time, the blade is set upward. The welding head 31 is longer, so the blade part of the blade body 46 does not interfere with the welding process of the welding head 31. The welding head 31 is turned on and the welding head 31 is controlled to move to the right side by the telescopic motor 33. The welding head 31 performs welding on the side edges of the other side of the two handle pieces 45. When the welding head 31 is separated from the handle piece 45, the lifting cylinder 41 is started, and the piston rod of the lifting cylinder 41 is extended. At this time, the flip plate 37 rotates clockwise, and the welding head 31 rotates to a state facing the lower left. At this time, the welding head 31 is close to the right end of the handle piece 45 again, and the welding head 31 is moved downward by the lifting motor 42, so that the right ends of the two handle pieces 45 are welded together. At this time, the upper and lower sides and the right ends of the two handle pieces 45 are welded, and the left end of the handle piece 45 and the blade body 46 are also welded, realizing the welding process of the entire tool. The welding head 31 and the blade slot 14 can be reset, and the welded tool can be taken out.

[0035] The present invention is applicable to a metal handle welding machine for kitchen knives. By arranging a U-shaped clamping head 9 to drive the blade body 46 to flip, after one clamping is completed, the positions that need to be welded between the blade body 46 and the handle piece 45 and between the two handle pieces 45 can all be welded by the welding head 31, thereby reducing the number of clamping times, not only improving the welding efficiency, but also improving the welding accuracy.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
