The left support block 411 is located on the left end side of the right support block 412, and the left support block 411 and the right support block 412 are arranged opposite to each other at intervals, and a mounting seat top plate 413 is installed between the upper end of the left support block 411 and the upper end of the right support block 412, and the left end of the mounting seat top plate 413 is screwed to the upper end of the left support block 411, and the right end of the mounting seat top plate 413 is screwed to the upper end of the right support block 412; the upper surface of the mounting seat top plate 413 is screwed with a clamping and fixing clamping block seat 421 arranged vertically, and the mounting seat top plate 413 is on the clamping and fixing clamping block seat A top plate avoidance groove 4131 which completely penetrates from top to bottom is provided on the side of the block seat 421, and a clamping movable clamping block seat 422 which is arranged vertically and directly faces the clamping fixed clamping block seat 421 is embedded in the top plate avoidance groove 4131, and the upper end of the clamping movable clamping block seat 422 extends to the upper end side of the mounting seat top plate 413, and the lower end of the clamping movable clamping block seat 422 extends to the lower end side of the mounting seat top plate 413, and the clamping fixed clamping block seat 42 1 is screwed with a clamping fixed profiling clamp block 431, and the clamping movable clamp block seat 422 is screwed with a clamping movable profiling clamp block 432 that matches the clamping fixed profiling clamp block 431; the lower end side of the mounting seat top plate 413 is equipped with a tool handle clamping driving cylinder 44 that is screwed on the upper surface of the mounting seat bottom plate 414 and moves horizontally left and right, and the outer extension end of the piston rod of the tool handle clamping driving cylinder 44 is connected to the lower end of the clamping movable clamp block seat 422.

[0046] It should be explained that the clamping drive mechanism 29 of the present invention can adopt the following structural design, specifically: the clamping drive mechanism 29 includes a clamping drive cylinder 291 which is screwed on the upper end of the rotating movable plate 26 and moves horizontally front and back, a driving swing arm 292 is installed between the clamping drive cylinder 291 and the grabbing movable clamp block seat 272, the upper end of the driving swing arm 292 is hinged to the extended end of the piston rod of the clamping drive cylinder 291 through a pivot, and the grabbing movable clamp block seat 272 is installed at the lower end of the driving swing arm 292; a cylinder body hinge seat is screwed on the front end of the cylinder body of the clamping drive cylinder 291, and a driving connecting rod 295 located on the lower end side of the piston rod of the clamping drive cylinder 291 is installed between the cylinder body hinge seat and the driving swing arm 292, the front end of the driving connecting rod 295 is hinged to the driving swing arm 292 through a pivot, and the rear end of the driving connecting rod 295 is hinged to the cylinder body hinge seat through a pivot. Before the tool handle grabbing assembly 2 grabs the tool handle, the piston rod of the clamping driving cylinder 291 is first in a retracted state; when grabbing, the piston rod of the clamping driving cylinder 291 pushes the upper end of the driving swing arm 292 forward, and in this process, the lower end of the driving swing arm 292 swings backward and causes the grabbing active profiling clamp block 282 and the grabbing fixed profiling clamp block 281 to close, so that the grabbing active profiling clamp block 282 and the grabbing fixed profiling clamp block 281 clamp the tool handle tightly. Among them, the grabbing active profiling clamp block 282 and the grabbing fixed profiling clamp block 281 of the present invention respectively adopt profiling design, and when the grabbing fixed profiling clamp block 281 and the grabbing active profiling clamp block 282 are closed and the tool handle is clamped and fixed, the grabbing fixed profiling clamp block 281 and the grabbing active profiling clamp block 282 are respectively attached to the surface of the tool handle.

[0047] It should be further pointed out that a material guide trough mounting frame 51 is screwed onto the side of the welding gun mounting frame 31 of the frame 1 , and a tool handle material guide trough 52 arranged in an inclined manner is screwed onto the upper end of the material guide trough mounting frame 51 .

[0048] For the tool handle grasping laser welding structure of the present invention, it is equipped with a PLC controller electrically connected to an external power supply. The X-axis drive linear module 21, Y-axis drive linear module 22, Z-axis drive linear module 23, rotation drive servo motor 25, clamping drive cylinder 291, and automatic laser welding gun 32 of the present invention are electrically connected to the PLC controller respectively; when working, the PLC controller controls the X-axis drive linear module 21, Y-axis drive linear module 22, Z-axis drive linear module 23, rotation drive servo motor 25, clamping drive cylinder 291, and automatic laser welding gun 32 to move.

[0049] For the tool handle clamping fixture 4 of the present invention, the mounting seat top plate 413 is installed with a control button for controlling the action of the tool handle clamping drive cylinder 44, and the control button is electrically connected to the PLC controller. When the staff presses the control button, the control button feeds back a signal to the PLC controller, and the PLC controller controls the action of the tool handle clamping drive cylinder 44, and the tool handle clamping drive cylinder 44 drives the clamping and grabbing movable clamp block seat 422 and the clamping and grabbing movable profiling clamp block 432 to act, so that the clamping and grabbing movable profiling clamp block 432 and the clamping and grabbing fixed profiling clamp block 431 are closed, and then the clamping and grabbing movable profiling clamp block 432 and the clamping and grabbing fixed profiling clamp block 431 clamp the assembled tool handle; of course, in addition to using the above-mentioned control button method, the present invention can use an inductive sensor method to automatically control the tool handle clamping drive cylinder 44. When the staff puts the tool handle in place, the inductive sensor feeds back a signal to the PLC controller, and the PLC controller controls the action of the tool handle clamping drive cylinder 44. In addition, during the process of clamping the tool handle by the tool handle clamping fixture 4 of the present invention, the staff works at the front side of the frame 1, and the staff aligns and assembles the two assembled metal parts that make up the tool handle together; after the two assembled metal parts that make up the tool handle are aligned and assembled together, the staff places the tool handle between the clamping and grabbing fixed profiling clamp block 431 and the clamping and grabbing movable profiling clamp block 432 of the front tool handle clamping fixture 4, and then presses the control button to close the clamping and grabbing fixed profiling clamp block 431 and the clamping and grabbing movable profiling clamp block 432. At this time, the tool handle formed by aligning and splicing two spliced ​​metal parts together is clamped and fixed between the clamping and grabbing fixed profiling clamp block 431 and the clamping and grabbing movable profiling clamp block 432. The clamping and grabbing fixed profiling clamp block 431 and the clamping and grabbing movable profiling clamp block 432 of the present invention respectively adopt profiling design. When the clamping and grabbing fixed profiling clamp block 431 and the clamping and grabbing movable profiling clamp block 432 are closed and the tool handle is clamped and fixed, the clamping and grabbing fixed profiling clamp block 431 and the clamping and grabbing movable profiling clamp block 432 are respectively attached to the surface of the tool handle.

[0050] The present invention is described in detail below in conjunction with a specific action process. Specifically: a worker aligns and assembles the two assembled metal parts constituting the tool handle, and places the tool handle formed by aligning and assembling the two assembled metal parts on the tool handle clamping fixture 4; after the tool handle is placed on the tool handle clamping fixture 4, the PLC controller controls the X-axis drive linear module 21, the Y-axis drive linear module 22, and the Z-axis drive linear module 23 to move and move the fixed profiling clamp block 281 and the movable profiling clamp block 282 to the tool handle grasping position Then the PLC controller controls the clamping drive cylinder 291 to move, and the clamping drive cylinder 291 drives the grabbing movable profiling clamp block 282 and the grabbing fixed profiling clamp block 281 to close and clamp the tool handle; after the tool handle is clamped, the PLC controller controls the X-axis drive linear module 21, the Y-axis drive linear module 22, and the Z-axis drive linear module 23 to move and move the clamped tool handle to the position of the automatic laser welding gun 32; after the clamped tool handle moves to the position of the automatic laser welding gun 32, the PLC controller controls the rotation drive servo motor 25, The X-axis drive linear module 21, the Y-axis drive linear module 22, and the Z-axis drive linear module 23 are in motion, wherein the rotation drive servo motor 25 drives the tool handle to rotate, and the rotation drive servo motor 25, the X-axis drive linear module 21, the Y-axis drive linear module 22, and the Z-axis drive linear module 23 work together to make the automatic laser welding gun 32 always align with the joint seam position of the tool handle, so that the automatic laser welding gun 32 performs laser welding on the joint seam position of the tool handle; after the laser welding of the tool handle is completed, the PLC controller controls the X-axis drive servo motor 25 to rotate the tool handle, and the PLC controller controls the X-axis drive servo motor 25 to rotate the tool handle. The dynamic linear module 21, the Y-axis driven linear module 22, and the Z-axis driven linear module 23 are in motion, and the welded tool handle is moved to the top of the tool handle guide groove 52; after the tool handle is moved to the top of the tool handle guide groove 52, the PLC controller controls the clamping drive cylinder 291 to move, and the clamping drive cylinder 291 drives the grabbing fixed profiling clamp 281 and the grabbing movable profiling clamp 282 to open and put the welded tool handle into the tool handle guide groove 52, and the tool handle guide groove 52 guides the welded tool handle to the corresponding storage box.

[0051] It should be emphasized that when the present invention is used to perform laser welding on the knife handle, there is no need to first achieve a fixed connection between the two spliced ​​metal parts by spot welding, which can effectively omit the spot welding process; in addition, the present invention can complete the laser welding operation on the spliced ​​seam position of the knife handle at one time, and the welding integrity of the entire spliced ​​seam position is better and the welding quality is better.

[0052] As a preferred embodiment, Figure 2 and Figure 3As shown, the rotating movable plate 26 is screwed with a clamping positioning block 210 extending horizontally forward between the clamping driving cylinder 291 and the grabbing fixed clamping block seat 271, and the clamping positioning block 210 is located at the upper end side of the grabbing movable profiling clamping block 282 and the grabbing fixed profiling clamping block 281. In the process of grabbing the tool handle by the tool handle grabbing assembly 2, the grabbing fixed profiling clamping block 281 and the grabbing movable profiling clamping block 282 are first moved to the top of the tool handle, and the tool handle is located between the grabbing fixed profiling clamping block 281 and the grabbing movable profiling clamping block 282, and then the Z-axis driving linear module 23 drives the grabbing fixed profiling clamping block 281 and the grabbing movable profiling clamping block 282 to move downward. When the clamping positioning block 210 hits the tool handle, it means that the grabbing fixed profiling clamping block 281 and the grabbing movable profiling clamping block 282 are moved down to the right position. By adding the clamping positioning block 210 structure, the present invention can effectively ensure the clamping position of the fixed profiling clamp block 281 and the movable profiling clamp block 282, thereby ensuring that the fixed profiling clamp block 281 and the movable profiling clamp block 282 can accurately clamp the tool handle.

[0053] In summary, it can be seen that through the above structural design, the present invention has the advantages of novel structural design, high degree of automation and high working efficiency. It should be pointed out that in addition to being applicable to the welding operation of a knife handle composed of two spliced ​​metal parts, the present invention can also be applicable to other products that need to be welded after two metal parts are spliced ​​together.

[0054] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
