[0014] In one embodiment, the pretreatment member includes a friction block and a plurality of protrusions. The top of the friction block is fixedly connected to the bottom of the top extension rod. A pushing slope is formed at one end of the bottom of the friction block away from the milling cutter, and the plurality of protrusions are all installed at the bottom of the friction block.

[0015] In the present invention, by setting the airbag assembly, the processing data is set according to the shape of the material. The processing data is the movement trajectories of the Z-axis moving table, the X-axis moving table, and the tool sliding assembly. Start the milling machine. The Z-axis moving table and the X-axis moving table drive the fixture and move the fixture below the tool sliding assembly. When the Z-axis moving table and the X-axis moving table drive the fixture below the milling cutter assembly, the side wall of the X-axis moving table will abut and squeeze the side wall of the abutting plate, and the first spring will contract, and the abutting plate will penetrate into the first spring groove; when the Z-axis moving table and the X-axis moving table drive the fixture below the milling cutter assembly, the side wall of the fixture will abut and squeeze the telescopic plate, and the telescopic plate will contract into the inside of the fixed plate; when the tool sliding assembly approaches the fixture, the extrusion plate of the tool sliding assembly will squeeze the vertical section of the airbag assembly, and the top of the vertical section will be compressed, and the air flow in the vertical section will blow out from the air outlet groove to form a first flushing air flow. The first flushing air flow is used to flush the surface of the material to prevent foreign matters from adhering to the surface of the material, thereby preventing the milling cutter from being affected during the processing of the material.

[0016] By setting the friction block, when the tool sliding assembly moves to the side of the fixture away from the airbag assembly, the drive motor rotates, and the drive gear, the belt, the driven gear, and the tool fixed rotating rod rotate following the drive motor, so that the milling cutter rotates to process the material. The milling machine starts to process the material. The friction block moves towards the material. When the pushing slope of the friction block abuts against the top of one end of the material, the friction block is lifted upward, the top extension rod moves upward following the friction block, the second spring is compressed, and the two "冂"-shaped clamping rods move upward following the top extension rod. The friction block continues to move towards the material, and the plurality of protrusions will abut against the top of the material for roughening pretreatment of the top of the material to prevent the milling cutter from slipping during work and prevent the milling cutter from breaking. At the same time, the restoring force of the second spring can enable the friction block to better contact and perform roughening pretreatment on the material.

[0017] By setting the horizontal section, when the milling cutter processes the material, the X-axis moving table will drive the fixture to move towards one side of the vertical section. The extrusion and contraction part on the side wall of the fixture will move along with the fixture towards one side of the vertical section. When the extrusion and contraction part moves along with the fixture towards one side of the vertical section, the extrusion and contraction part will extrude one end of the horizontal section adjacent to the lifting screw rod. The horizontal section is extruded and contracted, and the gas in the horizontal section is blown out from the air outlet groove to form a second flushing air flow. The second flushing air flow can not only be used to blow away the debris generated by the roughening pretreatment and the waste generated during the milling cutter processing, prevent the debris generated by the roughening pretreatment and the waste generated during the milling cutter processing from affecting the work of the milling cutter, but also can cool the milling cutter to prevent the milling cutter from being damaged due to excessive temperature during work.

[0018] By setting the air outlet groove, when the cleaning brush moves to the front of the air outlet groove, the second flushing air flow can flush the cleaning brush, so that the debris and waste remaining on the cleaning brush fall off, preventing the remaining debris and waste from affecting the subsequent processing, that is, the remaining debris and waste are scraped onto the material after the subsequent processing is completed. After the processing is completed, the Z-axis moving table, the X-axis moving table and the tool sliding assembly return to their original positions, and the material can be taken out without cleaning again, saving cleaning time and improving processing efficiency.

[0019] By setting the changeover switch, when the material to be processed is relatively large, when the pushing inclined surface of the friction block abuts against the top of one end of the material, the friction block is jacked up, the jacking rod moves upward along with the friction block, the second spring is compressed, and the two "冂"-shaped clamping rods move upward along with the jacking rod. The extrusion starting rod moves upward along with the friction block, and the extrusion starting rod will extrude the starting changeover switch, and the changeover switch is turned on, and the rotation speed of the milling cutter decreases, preventing the milling cutter from breaking when processing a relatively large material. When the pretreatment component is not needed, the clamping part can be pulled up before the milling machine is started. The two clamping rods slide in the two clamping grooves. When the lower ends of the two clamping rods abut against the tops of the two clamping grooves, the jacking rod is pulled up so that the friction block is pulled away from the material, and the clamping part is fixed by tightening the fixing nut, so that the material can be not pretreated.

[0020] The structure of the present invention is simple and can process the material well. During the processing, the material can be subjected to roughening pretreatment to prevent the milling cutter from slipping when contacting the material, thereby causing damage to the milling cutter. At the same time, by setting the air bag, the dust and foreign matters on the surface of the material can be blown away before the processing to prevent the dust and foreign matters from affecting the processing of the milling cutter. During the processing, it can not only be used to blow away the debris generated by the roughening pretreatment and the waste generated during the milling cutter processing, prevent the debris generated by the roughening pretreatment and the waste generated during the milling cutter processing from affecting the work of the milling cutter, but also can cool the milling cutter to prevent the milling cutter from being damaged due to excessive temperature during work. When encountering a relatively large material to be processed, there is no need to reprogram, and the low-frequency rotation speed can be automatically switched to prevent the milling cutter from breaking when processing a relatively large material. This device can also be used to process materials such as sapphire or silicon carbide. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] When in use: 1. Clamp the material in the fixture 24, set the processing data according to the shape of the material, the processing data is the moving trajectory of the Z-axis moving table 21, the X-axis moving table 22 and the tool sliding assembly 30, start the milling machine, the Z-axis moving table 21 and the X-axis moving table 22 drive the fixture 24, and move the fixture 24 to the bottom of the tool sliding assembly 30. When the Z-axis moving table 21 and the X-axis moving table 22 drive the fixture 24 to the bottom of the milling cutter assembly 40, the side wall of the X-axis moving table 22 will abut against the side wall of the abutment plate 17, the first spring 161 will contract, and the abutment plate 17 will go deep into the first spring groove 160; when the Z-axis moving table 21 When the X-axis movable table 22 drives the clamp 24 to the bottom of the milling cutter assembly 40, the side wall of the clamp 24 will abut against and squeeze the telescopic plate 251, and the telescopic plate 251 will shrink to the inside of the fixed plate 250; when the tool sliding assembly 30 approaches the clamp 24, the squeezing plate 36 of the tool sliding assembly 30 will squeeze the vertical section 72 of the airbag assembly 70, and the top of the vertical section 72 will be compressed. The airflow in the vertical section 72 will be blown out from the air outlet groove 73 to form a first flushing airflow. The first flushing airflow is used to flush the surface of the material to prevent foreign matter from sticking to the surface of the material, thereby preventing the milling cutter 43 from affecting the processing of the milling cutter 43 when processing the material.

[0045] 2. When the tool sliding assembly 30 moves to the side of the fixture 24 away from the airbag assembly 70, the drive motor 420 rotates, and the drive gear 422, the belt 425, the driven gear 424, and the tool fixed rotating rod 423 rotate following the drive motor 420, so that the milling cutter 43 rotates to process the material, and the milling machine starts to process the material. The friction block 530 moves towards the material. When the pushing inclined surface 532 of the friction block 530 abuts against the top of one end of the material, the friction block 530 jacks up, the jacking rod 520 moves upward following the friction block 530, the second spring 522 is compressed, and the two "冂"-shaped clamping rods 513 move upward following the jacking rod 520. The friction block 530 continues to move towards the material, and multiple bumps 531 will abut against the top of the material to perform roughening pretreatment on the top of the material, prevent the milling cutter 43 from slipping during work, prevent the milling cutter 43 from breaking, and at the same time, the restoring force of the second spring 522 can enable the friction block 530 to better contact and perform roughening pretreatment on the material.

[0046] 3. When the milling cutter 43 processes the material, the X-axis moving table 22 will drive the fixture 24 to move towards the side of the vertical section 72. The extrusion and contraction member 25 on the side wall of the fixture 24 will follow the fixture 24 to move towards the side of the vertical section 72. When the extrusion and contraction member 25 follows the fixture 24 to move towards the side of the vertical section 72, the extrusion and contraction member 25 will extrude one end of the horizontal section 71 adjacent to the lifting screw 32. The horizontal section 71 is extruded and contracted, and the gas in the horizontal section 71 blows out from the air outlet groove 73 to form a second flushing air flow. The second flushing air flow can not only be used to blow away the debris generated by the roughening pretreatment and the waste generated during the processing of the milling cutter 43, prevent the debris generated by the roughening pretreatment and the waste generated during the processing of the milling cutter 43 from affecting the work of the milling cutter 43, but also can cool the milling cutter 43 to prevent the milling cutter 43 from being damaged due to excessive temperature during work. The compression rate of the gas after the horizontal section 71 is extruded and contracted is greater than the blowing rate of the second flushing air flow to ensure that the second flushing air flow can blow away the debris generated by the roughening pretreatment and the waste generated during the processing of the milling cutter 43 and is used to cool the milling cutter 43.

[0047] 4. The X-axis moving stage 22 continues to drive the fixture 24 to move towards one side of the vertical section 72. The cleaning brush 62 of the cleaning assembly 60 can clean the debris and waste that the second flushing air flow on the fixture 24 fails to blow away, performing secondary cleaning. Finally, after the material processing is completed, there is no need to clean the fixture 24 and the material again, reducing the cleaning time and improving the processing efficiency. When the X-axis moving stage 22 drives the fixture 24 to move towards one side of the vertical section 72, the extrusion and contraction member 25 will continuously squeeze one end of the horizontal section 71 adjacent to the lifting screw 32 following the X-axis moving stage 22. The gas in the horizontal section 71 blows out the second flushing air flow from the air outlet groove 73. The second flushing air flow is continuously used to blow away the debris generated by the roughening pretreatment and the waste generated during the machining of the milling cutter 43, preventing the debris generated by the roughening pretreatment and the waste generated during the machining of the milling cutter 43 from affecting the work of the milling cutter 43. At the same time, it can also continuously cool the milling cutter 43 to prevent the milling cutter 43 from being damaged due to excessive temperature during work. When the cleaning brush 62 moves to the front of the air outlet groove 73, the second flushing air flow can wash the cleaning brush 62, causing the debris and waste remaining on the cleaning brush 62 to fall off, preventing the remaining debris and waste from affecting the subsequent processing, that is, the remaining debris and waste are scraped onto the material after the subsequent processing is completed. After the processing is completed, the Z-axis moving stage 21, the X-axis moving stage 22, and the tool sliding assembly 30 return to their original positions. Without cleaning again, the material can be taken out, saving the cleaning time and improving the processing efficiency.

[0048] 5. When the material to be processed is large, when the pushing inclined surface 532 of the friction block 530 abuts against the top of one end of the material, the friction block 530 is pushed upward, the top extension rod 520 moves upward following the friction block 530, the second spring 522 is compressed, and the two "冂"-shaped clamping rods 513 move upward following the top extension rod 520. The extrusion starting rod 523 moves upward following the friction block 530. The extrusion starting rod 523 will extrude the starting switch 427, and the switch 427 is turned on, and the rotation speed of the milling cutter 43 decreases, preventing the milling cutter 43 from breaking when processing a large material. When the pretreatment assembly 50 is not needed, the clamping member 51 can be pulled up before the milling machine is started. The two clamping rods 513 slide in the two clamping grooves 525. When the lower ends of the two clamping rods 513 abut against the tops of the two clamping grooves 525, the top extension rod 520 is pulled up so that the friction block 530 is pulled away from the material. By tightening the fixing nut 511 to fix the clamping member 51, the material can be not pretreated.

When starting the milling machine, the Z-axis moving table 21 and the X-axis moving table 22 drive the fixture 24 and move the fixture 24 below the tool sliding assembly 30. When the Z-axis moving table 21 and the X-axis moving table 22 drive the fixture 24 below the milling cutter assembly 40, the side wall of the X-axis moving table 22 will abut and squeeze the side wall of the abutting plate 17, the first spring 161 will contract, and the abutting plate 17 will sink into the first spring groove 160; when the Z-axis moving table 21 and the X-axis moving table 22 drive the fixture 24 below the milling cutter assembly 40, the side wall of the fixture 24 will abut and squeeze the telescopic plate 251, and the telescopic plate 251 will contract into the interior of the fixed plate 250; when the tool sliding assembly 30 approaches the fixture 24, the pressing plate 36 of the tool sliding assembly 30 will squeeze the vertical section 72 of the airbag assembly 70, the top of the vertical section 72 will be compressed, and the air flow in the vertical section 72 will be blown out from the air outlet groove 73 to form a first flushing air flow, which is used to flush the surface of the material to prevent foreign objects from adhering to the surface of the material, thereby preventing the milling cutter 43 from being affected during the processing of the material.

[0050] By providing a friction block 530, when the tool sliding assembly 30 moves to the side of the fixture 24 away from the airbag assembly 70, the driving motor 420 rotates, and the driving gear 422, the belt 425, the driven gear 424 and the tool fixed rotating rod 423 rotate following the driving motor 420 so that the milling cutter 43 rotates to process the material, and the milling machine starts to process the material. The friction block 530 moves towards the material. When the pushing inclined surface 532 of the friction block 530 abuts against the top of one end of the material, the friction block 530 jacks up, the top extension rod 520 moves upward following the friction block 530, the second spring 522 is compressed, and the two "冂"-shaped clamping rods 513 move upward following the top extension rod 520. The friction block 530 continues to move towards the material, and multiple convex blocks 531 will abut against the top of the material, which is used to perform roughening pretreatment on the top of the material to prevent the milling cutter 43 from slipping during work and prevent the milling cutter 43 from breaking. At the same time, the restoring force of the second spring 522 can enable the friction block 530 to better contact and perform roughening pretreatment on the material.

[0051] By setting the horizontal section 71, when the milling cutter 43 processes the material, the X-axis moving table 22 will drive the fixture 24 to move towards one side of the vertical section 72. The extrusion and contraction member 25 on the side wall of the fixture 24 will follow the fixture 24 to move towards one side of the vertical section 72. When the extrusion and contraction member 25 follows the fixture 24 to move towards one side of the vertical section 72, the extrusion and contraction member 25 will extrude one end of the horizontal section 71 adjacent to the lifting screw 32. The horizontal section 71 is extruded and contracted, and the gas in the horizontal section 71 is blown out from the air outlet groove 73 to form a second flushing air flow. The second flushing air flow can not only be used to blow away the debris generated by the roughening pretreatment and the waste generated during the processing of the milling cutter 43, prevent the debris generated by the roughening pretreatment and the waste generated during the processing of the milling cutter 43 from affecting the work of the milling cutter 43, but also can cool the milling cutter 43 to prevent the milling cutter 43 from being damaged due to excessive temperature during work.

[0052] By setting the air outlet groove 73, when the cleaning brush 62 moves to the front of the air outlet groove 73, the second flushing air flow can flush the cleaning brush 62, so that the debris and waste remaining on the cleaning brush 62 fall off, preventing the remaining debris and waste from affecting the subsequent processing, that is, the remaining debris and waste are scraped onto the material after the subsequent processing is completed. After the processing is completed, the Z-axis moving table 21, the X-axis moving table 22 and the tool sliding assembly 30 return to their original positions, and the material can be taken out without cleaning again, saving cleaning time and improving processing efficiency.

[0053] By setting the changeover switch 427, when the material to be processed is large, when the pushing inclined surface 532 of the friction block 530 abuts against the top of one end of the material, the friction block 530 is jacked up, the jacking rod 520 follows the friction block 530 to move upward, the second spring 522 is compressed, and the two "冂"-shaped clamping rods 513 follow the jacking rod 520 to move upward. The extrusion starting rod 523 follows the friction block 530 to move upward. The extrusion starting rod 523 will extrude the changeover switch 427, and the changeover switch 427 is turned on, and the rotation speed of the milling cutter 43 decreases, preventing the milling cutter 43 from breaking when processing a large material. When the pretreatment assembly 50 is not needed, the clamping member 51 can be pulled up before the milling machine is started. The two clamping rods 513 slide in the two clamping grooves 525. When the lower ends of the two clamping rods 513 abut against the tops of the two clamping grooves 525, the jacking rod 520 is pulled up so that the friction block 530 is pulled away from the material, and the clamping member 51 is fixed by tightening the fixing nut 511, so that the material can be not pretreated.

[0054] The present invention has a simple structure and can process materials well. During processing, the material can be roughened and pre-treated to prevent the milling cutter 43 from slipping when contacting the material, thereby causing damage to the milling cutter 43. At the same time, by setting an air bag, dust and foreign matter on the surface of the material can be blown away before processing to prevent dust and foreign matter from affecting the processing of the milling cutter 43. During processing, it can not only be used to blow away the debris generated by the roughening pre-treatment and the waste generated by the milling cutter 43, but also prevent the debris generated by the roughening pre-treatment and the waste generated by the milling cutter 43 from affecting the work of the milling cutter 43. At the same time, it can also cool the milling cutter 43 to prevent the milling cutter 43 from being damaged by excessive temperature during operation. When encountering a large material to be processed, there is no need to reprogram, and the low-frequency speed can be automatically switched to prevent the milling cutter 43 from breaking when processing a large material.
