[0052] Please refer to Fig. 9 and Fig.10 As shown, the additive mechanism 3 also includes a third screw rod 315 and a third fixed rod 316. The third screw rod 315 is rotatably connected to the inside of the first connecting frame 314, and the third fixed rod 316 is fixedly installed in the inside of the first connecting frame 314. The outer surface of the third screw rod 315 is threadedly connected to the first movable frame 318, and the first movable frame 318 is slidably connected to the third fixed rod 316. A third stepper motor 317 is arranged on the outside of the first connecting frame 314, and the output end of the third stepper motor 317 is fixedly connected to one end of the third screw rod 315. The inside of the first movable frame 318 is rotatably connected to the first rotating frame 319, and the outside of the first movable frame 318 is provided with a first motor 320 that drives the first rotating frame 319 to rotate.

[0053] It can be understood by those skilled in the art that the first screw rod 301 is driven to rotate by the output end of the first stepper motor 303, so that the first movable block 304 reciprocates left and right along the first fixed rod 302, and drives the print head 323 to reciprocate left and right; the second screw rod 307 is driven to rotate by the output end of the second stepper motor 308, so that the first L-shaped block 309 reciprocates back and forth along the second fixed rod 305, and drives the print head 323 to reciprocate back and forth; the first connecting frame 314 is driven to reciprocate up and down by the output end of the first electric push rod 310, so that the print head 323 reciprocates up and down. In summary, the print head 323 can move in three directions: horizontal, vertical and vertical; the first rotating frame 319 is driven to rotate left and right by the output end of the first motor 320, so that the print head 323 rotates left and right, and the first rotating member 321 is driven to rotate back and forth by the output end of the second motor 322, so that the print head 323 rotates back and forth. Through the coordinated use of the first motor 320 and the second motor 322, the angle of the print head 323 is changed, thereby improving the practicality of the device;
[0054] It is worth mentioning here that in daily life, when 3D printing technology is used to produce special-shaped products, some parts of the special-shaped products are arc-shaped. The traditional technology is to drive the print head 323 to move and print little by little, which is more troublesome. The present invention drives the first drive gear 312 to rotate through the output end of the first drive motor 311, so that the first driven gear 313 and the first electric push rod 310 rotate as a whole, and the output end of the first electric push rod 310 is fixedly installed with a first connecting frame 314, which can drive the first connecting frame 314 to rotate, thereby driving the print head 323 to rotate with the first electric push rod 310 as the center of the circle, and the output end of the third stepping motor 317 drives the third screw rod 315 to rotate, so that the first movable frame 318 slides back and forth along the outer surface of the third fixed rod 316, and then the print head 323 also slides back and forth along the outer surface of the third fixed rod 316, so that the position of the print head 323 changes, and the print head 323 is equivalent to changing the "radius" when it rotates around the first electric push rod 310 next time;
[0055] Therefore, when 3D printing the arc part on the special-shaped product, it is only necessary to determine the starting point and the end point of the arc part, and then find the position of the center of the arc, so as to determine the radius of the arc. The first stepper motor 303 and the second stepper motor 308 are used together to make the first electric push rod 310 move to the center position of the arc to be printed, and then under the action of the third stepper motor 317, the print head 323 changes position along the third fixed rod 316 to adjust the radius, and then the output end of the first drive motor 311 is used to make the print head 323 rotate to above the starting point of the arc, and the output end of the first electric push rod 310 drives the print head 323 to move downward and fall on the starting point of the arc, and finally the output end of the first drive motor 311 continues to drive the print head 323 to rotate from the starting position to the end position, so as to realize the printing of the arc part.

[0061] It can be understood by those skilled in the art that the mechanical structure of the subtractive mechanism 5 is the same as that of the additive mechanism 3, and no further explanation will be given here. In essence, the milling head 523 can be driven to move in the horizontal, vertical and vertical directions. The milling angle of the milling head 523 can be changed, and the milling head 523 can be rotated around the third electric push rod 512. The produced special-shaped products can be polished to make the surface of the special-shaped products smoother and brighter. Similarly, the arc part of the special-shaped products can also be quickly polished to meet the needs of the staff.
[0062] Working principle and use process of the device: In order to better describe the principle of the present invention, we draw a workpiece 102 and an additive body 103. The workpiece 102 in the present invention is a metal plate, and the additive body 103 in the present invention is a wrench seen in life (such as Fig.16 and Fig.17 As shown), in fact, the device of the present invention can print out other special-shaped additive bodies 103; first, we use the manipulator 101 to grab the external workpiece 102 and transfer it to the clamping mechanism 2. The clamping mechanism 2 clamps and fixes the metal plate-shaped workpiece 102. The print head 323 can move in three directions, horizontally, vertically and vertically, and the angle of the print head 323 can be adjusted, which can be well applied to the plane part of special-shaped products for printing. It is worth noting that the special-shaped products seen in daily life have arc parts, such as wrenches, which are not planes. Of course, the same method as plane printing is used. It only needs to adjust and move the print head 323 a little bit, and the arc part can also be printed. However, this method is less efficient. The staff first determines the starting point and end point of the arc part, and then finds the arc part. The position of the center of the arc is determined, thereby determining the radius of the arc. The first stepper motor 303 and the second stepper motor 308 are used in conjunction to make the first electric push rod 310 move to the center of the arc to be printed, and then under the action of the third stepper motor 317, the print head 323 changes position along the third fixed rod 316 to adjust the radius. Then, the output end of the first drive motor 311 is used to make the print head 323 rotate to above the starting position of the arc, and the output end of the first electric push rod 310 drives the print head 323 to move downward and fall on the starting point of the arc. Finally, the output end of the first drive motor 311 continues to drive the print head 323 to rotate from the starting position to the end position, thereby realizing the printing of the arc part. Compared with the traditional printing method, the efficiency is improved and the production speed of special-shaped products is accelerated.
[0063] After the additive body 103 is printed and formed, the additive body 103 is still connected to the workpiece 102. The fourth lead screw 401 is driven to rotate by the output end of the fourth stepper motor 403, so that the cutting knife 410 moves to a height that matches the top of the workpiece 102. The cutting knife 410 is driven to rotate by the output end of the third motor 409. The fifth lead screw 405 is driven to rotate by the output end of the fifth stepper motor 407, so that the rotating cutting knife 410 reciprocates left and right to cut the additive body 103 from the workpiece 102. In order not to interfere with the cutting process, the output end of the second electric push rod 413 is in a retracted state, that is, the grinding piece 416 is located at the cutting knife 410. Above, and under the action of the output end of the second driving motor 411, the grinding piece 416 is rotated to the rear side; after the cutting of the additive body 103 is completed, the manipulator 101 grabs the additive body 103 to the table 105, and the manipulator 101 can clamp and fix the additive body 103 and flip it, and the milling head 523 moves in the horizontal, vertical and vertical directions, and the milling angle of the milling head 523 can also change, and the milling head 523 can rotate around the third electric push rod 512, so as to realize the polishing of the additive body 103, so that the surface of the special-shaped additive body 103 is smoother and brighter, and similarly, the arc part of the additive body 103 can also be quickly polished, which meets the needs of the staff;
[0064] While the additive body 103 is being polished, the workpiece 102 is still in a clamped state, and the output end of the second electric push rod 413 moves downward, driving the grinding piece 416 to be below the cutting knife 410, and then under the action of the output end of the second drive motor 411, the grinding piece 416 rotates to face the front side, and the output end of the fifth stepper motor 407 drives the fifth lead screw 405 to rotate, so that the grinding piece 416 reciprocates left and right. Since there are burrs on the top of the workpiece 102 after cutting, polishing can be achieved through this operation, and after polishing, the printing operation is repeated, and the additive body 103 can still be printed on the top of the workpiece 102, thereby ensuring the continuity of production and improving the production efficiency of the additive body 103.
