A loading robot arm 101 is installed on the left side of the box body 1, and a loading clamp 102 is detachably connected to the end of the loading robot arm 101.

[0045] Example 2

[0046] Please refer to Figure 5 As shown, the fixing mechanism 2 includes two groups of first fixing blocks 201, and the two groups of first fixing blocks 201 are welded to the top of the rotating disk 105. The middle parts of the two groups of first fixing blocks 201 are rotatably connected to the first threaded rod 202 through bearings. The threads opened at both ends of the first threaded rod 202 rotate in opposite directions, and both ends of the outer surface of the first threaded rod 202 are threadedly connected to a movable plate 205, and the top of the movable plate 205 is detachably connected to a clamping plate 206. A first servo motor 204 that drives the first threaded rod 202 to rotate is provided on the outer side of one group of first fixing blocks 201, and the two groups of movable plates 205 are slidably connected to the first fixing rod 203, and the first fixing rod 203 is welded between the two groups of first fixing blocks 201.

[0047] Those skilled in the art can understand that, by driving the first threaded rod 202 to rotate through the output end of the first servo motor 204, the two sets of movable plates 205 are moved closer to or away from each other, thereby driving the two sets of clamping plates 206 to move closer to or away from each other, and when they are close to each other, the workpiece to be engraved and milled is clamped, and the clamping plates 206 and the movable plates 205 are detachably connected, so the clamping plates 206 can be adapted and replaced according to the shape of the workpieces to be engraved and milled in batches, thereby improving the practicality and applicability of the device.

[0048] Example 3

[0049] Please refer to Figure 5 and Figure 6 As shown, the clamping mechanism 3 includes a second threaded rod 302 and a second fixed rod 303, two groups of second fixed blocks 301 are fixedly installed on the right side of the flip member 103, the second threaded rod 302 is rotatably connected between the two groups of second fixed blocks 301, the second fixed rod 303 is fixedly connected between the two groups of second fixed blocks 301, and two groups of clamping members 305 are slidably connected to the second fixed rod 303, the outer end of the second threaded rod 302 is fixedly installed on the output end of the second servo motor 304, the second servo motor 304 is arranged on the outside of one group of second fixed blocks 301, and the two groups of clamping members 305 are respectively threadedly connected to the two ends of the outer surface of the second threaded rod 302, and the threads opened at both ends of the second threaded rod 302 have opposite rotation directions, and the anti-splash frame 111 has slots adapted to the clamping members 305 on both sides.

[0050] Those skilled in the art can understand that, by driving the second threaded rod 302 to rotate through the output end of the second servo motor 304, the two groups of clamping members 305 are brought closer to or away from each other. When approaching, the two groups of clamping members 305 are respectively stuck in the slots on both sides of the anti-splash frame 111, so that the anti-splash frame 111 is fixedly installed on the top of the flip member 103.

[0051] Example 4

[0052] Please refer to Figure 7 、 Figure 8 and Figure 9As shown, the knife storage mechanism 4 includes a fixed frame 401, which is fixedly connected to the front top of the box body 1 by bolts, and a first screw rod 402 is rotatably connected in the fixed frame 401, and a moving part 405 is threadedly connected to the first screw rod 402, and a first stepper motor 404 is installed on the outside of the fixed frame 401, and the output end of the first stepper motor 404 extends into the fixed frame 401 and is fixedly connected to the outer end of the first screw rod 402, and a first guide rod 403 is also welded in the fixed frame 401, and the moving part 405 is slidably connected to the first guide rod 403, and a plurality of groups of storage grooves 406 are opened on the top of the moving part 405, and the storage grooves 406 store cutting tools 109, and the inner bottom end of the storage grooves 406 is connected to the lifting block 408 through a first spring 407, and a magnet 409 is also installed on the inner wall of the storage grooves 406.

[0053] Those skilled in the art will appreciate that, by driving the first screw rod 402 to rotate through the output end of the first stepper motor 404, the movable member 405 reciprocates left and right, and by driving the right cover plate 112 to rotate through the output end of the third drive motor 113 on the right side, the square hole on the right side of the anti-splash frame 111 is opened, and when the movable member 405 moves to the left, several groups of cutting tools 109 can be delivered into the interior of the anti-splash frame 111, so that the installation mechanism 5 can replace the cutting tools 109.

[0054] The reason why the present invention sets the movable part 405 for storing the tool 109 outside the anti-splash frame 111 is that during the engraving and milling process, the tool 109 needs to be sprayed with cooling water. If it is set inside the anti-splash frame 111, the splashed "waste chips" generated during engraving and milling can enter the storage tank 406. Due to the presence of cooling water liquid, the "waste chips" are very easy to adhere to the inner wall of the storage tank 406 and the outer wall of the stored tool 109, making it difficult to clean.

[0055] Example 5

[0056] Please refer to Figure 5 、 Figure 10 and Figure 11 As shown, the mounting mechanism 5 includes an iron cylinder 501 and a through slot 503. A limiting slot is provided on the inner wall of the connecting cylinder 108. A limiting block is installed on the iron cylinder 501, and the limiting block is slidably connected in the limiting slot. The through slot 503 is provided with three groups of evenly distributed through the outer wall of the iron cylinder 501. A movable block 506 is slidably installed in the iron cylinder 501. The inner wall of the iron cylinder 501 is fixedly connected to the movable block 506 through a second spring 505. Three groups of balls 502 are also provided in the iron cylinder 501, and a first through hole 504 is provided through the middle position of the outer end of the iron cylinder 501, and a second through hole 507 is provided through the center position of the movable block 506.

[0057] Please refer to Figure 8As shown, the top of the cutter 109 is conical, and an annular groove 115 is provided on the top of the outer wall of the cutter 109 .

[0058] Those skilled in the art will appreciate that, under the action of the output end of the first stepper motor 404, the movable member 405 storing the tool 109 enters the anti-splash frame 111, and the engraving and milling robot arm 107 can rotate in multiple axes. Under the action of the engraving and milling robot arm 107, the connecting cylinder 108 is driven to move, so that the first through hole 504 is aligned with the top of a tool 109 stored in the movable member 405, and the connecting cylinder 108 is continued to move downward. The first spring 407 is in a contracted state, so that the top of the tool 109 is inserted into the inside of the first through hole 504, and the three groups of balls 502 are pushed outward, and move upward together with the iron cylinder 501. The second spring 505 presses the movable block 506 downward, driving the balls 502 to press outward. At the same time, the balls 502 are squeezed by the inner wall of the connecting cylinder 108, so that the three groups of balls 502 are all inside the retaining ring groove 115, thereby locking and fixing the tool 109, thereby achieving installation of the tool 109.

[0059] When disassembling the tool 109, it is only necessary to put the tool 109 back into its corresponding storage slot 406 under the action of the engraving and milling robot arm 107, and drive the connecting cylinder 108 downward through the engraving and milling robot arm 107, so that the first spring 407 is always in a contracted state. After the connecting cylinder 108 enters the storage slot 406 and the iron cylinder 501 is close to the magnet 409, on the contrary, the iron cylinder 501 moves downward under the magnetic force of the magnet 409, and the three groups of balls 502 have enough space to move outward, thereby unlocking the tool 109. The connecting cylinder 108 can be quickly pulled out upward under the action of the engraving and milling robot arm 107, and the disassembly of the tool 109 is completed.

[0060] Example 6

[0061] Please refer to Figure 12 As shown, the auxiliary mechanism 6 includes an electric lifting rod 601, a lifting frame 602 and a movable bar 606. The electric lifting rod 601 is fixedly connected to the internal top of the box body 1, and the lifting frame 602 is fixedly installed at the output end of the electric lifting rod 601. A third threaded rod 603 is rotatably connected in the lifting frame 602. The threads at both ends of the third threaded rod 603 rotate in opposite directions. The movable bar 606 is provided with two groups and is respectively threadedly connected to the two ends of the outer surface of the third threaded rod 603. A third servo motor 605 is provided on the inner wall of the lifting frame 602. The outer end of the third threaded rod 603 is fixedly connected to the output end of the third servo motor 605, and a third fixed rod 604 is also welded in the lifting frame 602. The movable bar 606 is slidably connected to the third fixed rod 604.

[0062] Please refer to Figure 13As shown, a fourth drive motor 612 is fixedly installed on the outer wall of the movable bar 606, and the output end of the fourth drive motor 612 passes through the outer wall of the movable bar 606 and is fixedly connected to the middle part of the outer side of the rotating frame 607. A fourth fixed rod 609 is fixedly installed in the rotating frame 607, and two groups of clamping blocks 611 are slidably connected to the fourth fixed rod 609. The two groups of clamping blocks 611 are respectively threadedly connected to the two ends of the outer surface of the fourth threaded rod 608, and the fourth threaded rod 608 is rotatably connected in the rotating frame 607. A fourth servo motor 610 for driving the fourth threaded rod 608 to rotate is provided on the outer side of the rotating frame 607.

[0063] Those skilled in the art can understand that, the lifting frame 602 is driven to move up and down by the output end of the electric lifting rod 601, thereby realizing the up and down movement of the clamping block 611; the third threaded rod 603 is driven to rotate by the output end of the third servo motor 605, so that the two groups of movable bars 606 are close to or away from each other; and the fourth threaded rod 608 is driven to rotate by the output end of the fourth servo motor 610, so that the two groups of clamping blocks 611 are close to or away from each other; and because the rotating frame 607 has its own gravity, if it is to be in a horizontal state at all times, the present invention is correspondingly provided with a fourth drive motor 612, and the output end of the fourth drive motor 612 is similar to a fan motor in life.

[0064] Example 7

[0065] Please refer to Figure 14 As shown, the flushing mechanism 7 includes a second screw rod 701 and a second guide rod 702. The second screw rod 701 is rotatably connected to the box body 1, and the second guide rod 702 is welded to the box body 1. A second stepper motor 703 is provided on the outside of the box body 1. The output end of the second stepper motor 703 extends into the box body 1 and is fixedly connected to the second screw rod 701. A high-pressure nozzle 704 is threadedly connected to the second screw rod 701, and the high-pressure nozzle 704 is slidably connected to the second guide rod 702.

[0066] Those skilled in the art will appreciate that the second screw rod 701 is driven to rotate by the output end of the second stepping motor 703 , so that the high-pressure nozzle 704 can reciprocate along the second guide rod 702 .

[0067] In order to clearly describe the working principle of the present invention, we use Figure 1 To explain the azimuth perspective:

[0068] S1. The present invention cooperates with a loading robot arm 101 and a loading fixture 102, and the loading fixture 102 is detachable at the end of the loading robot arm 101, so that workpieces of different shapes can be loaded. When loading, the cover plate 112 on the left is driven to rotate by the output end of the third driving motor 113 on the left, and the square hole on the left side of the anti-splash frame 111 is opened, and the workpiece to be engraved and milled is placed on the top of the rotating disk 105. The first threaded rod 202 is driven to rotate by the output end of the first servo motor 204, so that the two sets of movable plates 205 are close to each other to clamp the workpiece to be engraved and milled, and the clamping plate 206 is also detachably connected to the movable plate 205. Therefore, the clamping plate 206 can be adapted and replaced according to the shape of the workpieces to be engraved and milled in batches, thereby improving the practicality and applicability of the device.

[0069] S2, the cover plate 112 on the left is driven to rotate by the output end of the third drive motor 113 on the right side, the square hole on the right side of the anti-splash frame 111 is opened, and the first screw rod 402 is driven to rotate by the output end of the first stepper motor 404, so that the moving part 405 moves to the left, and several groups of tools 109 are sent into the interior of the anti-splash frame 111. Under the action of the engraving and milling robot 107, the connecting cylinder 108 is driven to move so that the first through hole 504 is aligned with a tool 109 stored in the moving part 405, and the connecting cylinder 108 is continued to move. When the tool 109 moves downward, the first spring 407 is in a contracted state, so that the top of the tool 109 is inserted into the first through hole 504, and the three sets of balls 502 are pushed outward, and together with the iron cylinder 501, they also move upward. The second spring 505 presses the movable block 506 downward, driving the balls 502 to press outward. At the same time, the balls 502 are squeezed by the inner wall of the connecting cylinder 108, so that the three sets of balls 502 are all inside the retaining ring groove 115, thereby locking the tool 109 and realizing the selective and quick installation of the tool 109 according to the needs.

[0070] S3. After the tool 109 is installed, the cover plates 112 on the left and right sides close the square holes on both sides, so that the subsequent engraving and milling process is in a closed state, and the "waste chips" generated will not be scattered outside the anti-splash frame 111. After that, the engraving and milling robot arm 107 and the tool 109 are used in conjunction with each other, and the output end of the second drive motor 106 drives the rotating disk 105 to rotate, driving the clamped workpiece to rotate, so that multi-range engraving and milling of the workpiece can be achieved. During the engraving and milling process, the water-cooling nozzle 110 sprays cooling water to the tool 109, thereby improving the life of the tool 109;

[0071] S4. Due to the presence of cooling water, the "waste chips" generated during the engraving and milling process are very likely to adhere to the inner wall of the anti-splash frame 111, the top of the flip member 103 and the top of the rotating disk 105. If it is necessary to clean them, the output end of the first drive motor 104 drives the flip member 103 to rotate 180 degrees so that the anti-splash frame 111 faces downward, and the high-speed hot fan 114 is started to blow hot air to the top of the flip member 103 and the top of the rotating disk 105, so that the cooling water and the adhered "waste chips" on the top of the flip member 103 and the top of the rotating disk 105 fall into the anti-splash frame 111 together;

[0072] S5. After that, the output end of the electric lifting rod 601 drives the lifting frame 602 to move upward. Under the cooperation of the output end of the third servo motor 605 and the output end of the fourth servo motor 610, the four groups of clamping blocks 611 clamp the outer wall of the anti-splash frame 111, and the clamping mechanism 3 releases the clamping of the anti-splash frame 111. Then, the output end of the electric lifting rod 601 drives the lifting frame 602 to move downward to the reset state, and the output end of the first drive motor 104 also drives the flip member 103 to the reset state. Then, under the cooperation of the output end of the fourth drive motor 605, the four groups of clamping blocks 611 clamp the outer wall of the anti-splash frame 111. The clamping mechanism 3 releases the clamping of the anti-splash frame 111. Under the action of the output end of the motor 612, the opening at the top of the anti-splash frame 111 is facing downward, and the second screw rod 701 is driven to rotate by the output end of the second stepper motor 703, so that the high-pressure nozzle 704 reciprocates left and right. The high-pressure nozzle 704 sprays cleaning water into the inside of the anti-splash frame 111, flushes the inner wall of the anti-splash frame 111, and flushes the "waste chips" into the inside of the box body 1. The cleaning water will also fall into the box body 1, which is convenient for reuse and can also be used as cooling water in the engraving and milling process, meeting the needs of the staff.
