[0002] A milling machine refers to a machine tool that uses a milling cutter to process various surfaces of a workpiece. Usually, the rotational movement of the milling cutter is the main movement, and the movement of the workpiece and the milling cutter is the feed movement. On a milling machine, planes, grooves, toothed parts, spiral surfaces, and various curved surfaces can be processed. It can also be used for machining the surface of a rotating body, internal holes, and cutting work, etc. When the milling machine is working, the workpiece is installed on the workbench or attachments such as a dividing head. The rotation of the milling cutter is the main movement, supplemented by the feed movement of the workbench or the milling head, and the required machined surface of the workpiece can be obtained.

[0041] Such as Figures 1 to 3As shown in the figure, an embodiment of the present invention provides a cutting device for drone processing, including a milling machine body 1. A Y-axis lead screw platform 2 is fixedly connected to the milling machine body 1. An X-axis lead screw platform 3 is fixedly connected to the lead screw nut of the Y-axis lead screw platform 2. The milling machine body 1, the Y-axis lead screw platform 2, and the X-axis lead screw platform 3 are all prior arts. A workpiece operation platform 4 is fixedly connected to the lead screw nut of the X-axis lead screw platform 3. The bottom of the workpiece operation platform 4 is fixedly connected to the X-axis lead screw platform 3. The workpiece operation platform 4 is used to place the drone workpiece to be processed. A number of uniformly arranged clamping holes 41 are provided on the workpiece operation platform 4. The clamping holes 41 penetrate through the workpiece operation platform 4, which is convenient for discharging the waste chips generated during the processing of the drone workpiece and at the same time provides an installation space for the clamping structure 5. The clamping structure 5 is located inside the clamping hole 41 and is detachably connected thereto. The clamping structure 5 is used to limit and clamp the drone processing parts. The irregular drone workpiece can be clamped by the clamping structure 5, and after the workpiece processing is completed, it is convenient to fixedly clamp the next workpiece to be processed. The clamping structure 5 includes a base component 51 detachably connected to the inside of the clamping hole 41. The base component 51 is used to fix the entire clamping structure 5 in the clamping hole 41. At the same time, when it is necessary to replace the processed workpiece, it can cooperate with the adjustment component 52 to release the limit on the workpiece without removing the base component 51. An adjustment component 52 is slidably connected to the base component 51. The adjustment component 52 is used to provide an installation platform for the workpiece limit component 54 and at the same time is adapted to the base component 51 to adjust the workpiece limit component 54. An internal gear ring 53 is fixedly connected to the adjustment component 52. The internal gear ring 53 is used to clamp and limit the workpiece limit component 54. The workpiece limit component 54 is clamped inside the internal gear ring 53. The workpiece limit component 54 is used to limit and fix the drone workpiece to be processed. The irregular workpiece can be cooperatively limited by a number of workpiece limit components 54 so that it will not shift during the processing.

[0042] When cutting and processing the drone workpiece, place the drone workpiece to be processed on the workpiece operation platform 4. According to the shape of the workpiece, selectively fix the clamping structure 5 on the clamping holes 41 around the workpiece. The workpiece is limited and fixed by a number of workpiece limit components 54, so as to fix the workpiece on the workpiece operation platform 4, and then carry out the processing procedure of the workpiece.

[0043] As Figure 2 and Figures 4 to 6As shown, the base assembly 51 includes a first rotating column 511 and a second rotating column 512 that are rotatably connected. The diameters of the first rotating column 511 and the second rotating column 512 are the same. The first rotating column 511 and the second rotating column 512 are rotatably connected by a rotating shaft. At both ends of the outer surface wall of the first rotating column 511, a first sliding sleeve 516 and an embedding column 514 are respectively sleeved. The length of the first sliding sleeve 516 is 1 / 4 of the length of the embedding column 514, and the diameter of the first sliding sleeve 516 is smaller than the diameter of the embedding column 514. The diameter of the embedding column 514 is slightly smaller than the diameter of the clamping hole 41. A second sliding sleeve 517 is sleeved on the outer surface wall of the second rotating column 512. The diameter of the second sliding sleeve 517 is the same as the diameter of the first sliding sleeve 516. The diameters of the first sliding sleeve 516 and the second sliding sleeve 517 are the same, so that the open end of the adjusting sleeve 521 can slide from the second sliding sleeve 517 to the first sliding sleeve 516. Four corresponding sliding grooves 518 are provided on the outer surface walls of the first sliding sleeve 516 and the second sliding sleeve 517. The sliding grooves 518 are used to be adapted to the sliding rods 523, so that while the adjusting sleeve 521 can slide on the first sliding sleeve 516 and the second sliding sleeve 517, they will not rotate relative to each other. The four sliding grooves 518 are distributed at 90° to each other. It further includes a first clamping unit for detachably connecting the embedding column 514 to the clamping hole 41. The first clamping unit is used to limit and fix the embedding column 514 in the clamping hole 41, facilitating the placement and removal of the embedding column 514.

[0044] As Figure 2 , Figure 5 and Figure 6 shown, the first clamping unit includes a first clamping piece 515 fixedly connected to the outer surface wall of the embedding column 514. The first clamping piece 515 is connected by a first limiting section 5151 and two supporting sections 5152. The first limiting section 5151 is a ring-shaped elastic sheet structure that is convex in the middle and concave on both sides. The two ends of the first limiting section 5151 are fixedly connected to the outer surface wall of the embedding column 514. The two ends of the supporting section 5152 are respectively fixedly connected to the inner surface wall of the concave section of the first limiting section 5151 and the outer surface wall of the embedding column 514 corresponding to the center of the convex section of the first limiting section 5151. The two supporting sections 5152 are symmetrically installed in the gap between the first limiting section 5151 and the embedding column 514. A first clamping groove adapted to the shape of the first clamping piece 515 is provided on the inner surface wall of the clamping hole 41. The embedding column 514 and the clamping hole 41 are adaptively clamped through the first clamping piece 515 and the first clamping groove.

[0045] When the embedding post 514 is gradually inserted into the clamping hole 41, during the insertion process of the embedding post 514, the first limiting section 5151 of the first clamping piece 515 will contact the orifice wall of the clamping hole 41, and the orifice wall will squeeze the concave section, causing it to undergo compressive deformation. When the concave section is squeezed, it will also squeeze the supporting section 5152. Since the thickness of the supporting section 5152 gradually changes from thin to thick from the middle to both ends, when the supporting section 5152 is subjected to the squeezing force, it will undergo compressive deformation until the entire first clamping piece 515 is compressed and snapped into the clamping hole 41. When it moves to the first clamping groove inside the clamping hole 41, after the two supporting sections 5152 lose the squeezing force of the hole wall, they recover their deformation, thereby driving the first limiting section 5151 to recover its deformation, and then snapping into the first clamping groove to fix the embedding post 514 in the clamping hole 41.

[0046] Such as Figure 4 And Figure 8As shown, the adjusting assembly 52 includes an adjusting sleeve 521 slidably connected to the second sliding sleeve 517. The adjusting sleeve 521 is used to provide an installation position for the inner gear ring 53 and the workpiece stop assembly 54, and can drive the inner gear ring 53 and the workpiece stop assembly 54 installed thereon to slide on the second sliding sleeve 517. The inner ring diameter of the adjusting sleeve 521 is consistent with the outer ring diameter of the first sliding sleeve 516. When the adjusting sleeve 521 slides to the outer wall of the first sliding sleeve 516, the adjusting sleeve 521 will move the first sliding sleeve 516 and the second sliding sleeve 517. The first rotating column 511 and the second rotating column 512 are wrapped inside the adjusting sleeve 521, so that the first rotating column 511 and the second rotating column 512 will not rotate and deviate. The inner surface wall of the adjusting sleeve 521 is provided with four sliding rods 523 adapted to the sliding groove 518. The sliding rods 523 are located at the lower end of the inner surface wall of the adjusting sleeve 521. The sliding rods 523 are used to slide and limit the adjusting sleeve 521 to increase the strength of the adjusting sleeve 521. At the same time, when the sliding rods 523 are located at the sliding grooves 518 on the first sliding sleeve 516 and the second sliding sleeve 517 at the same time, it can help prevent the first rotating column 511 from rotating and deviating. 11 and the second rotating column 512 are offset, and the length of the sliding rod 523 is 1 / 2 of the distance between the farthest ends of the sliding groove 518 on the first sliding sleeve 516 and the sliding groove 518 on the second sliding sleeve 517. Therefore, when the adjusting sleeve 521 slides to the uppermost end of the sliding groove 518 on the second sliding sleeve 517, the adjusting sleeve 521 will expose the first rotating column 511 and the second rotating column 512. When it is necessary to release the limit of the workpiece to be processed, it is only necessary to slide the adjusting sleeve 521 upward to expose the first rotating column 511 and the second rotating column 512, thereby bending the adjusting sleeve 521. 1, which can drive the second rotating column 512 to rotate on the first rotating column 511, so that the workpiece limiting assembly 54 on the adjusting sleeve 521 is offset, thereby releasing the limiting position with the workpiece. The outer wall of the adjusting sleeve 521 is provided with a mounting groove 522, and also includes a second clamping unit for clamping the adjusting sleeve 521 and the first sliding sleeve 516 with each other. The second clamping unit is used to increase the fixing strength between the adjusting sleeve 521 and the first sliding sleeve 516 when fixing the workpiece, so as to prevent the adjusting sleeve 521 from sliding up due to vibration during the workpiece cutting operation.

[0047] like Figure 4 , Figure 8 and Figure 9As shown, the second clamping unit includes a second clamping piece 524 fixedly connected to the inner wall of the opening end of the adjusting sleeve 521. A second clamping groove 513 is formed on the outer wall of one end of the first sliding sleeve 516 close to the embedding column 514. The adjusting sleeve 521 and the first sliding sleeve 516 are clamped together through the cooperation of the second clamping piece 524 and the second clamping groove 513. The second clamping piece 524 is connected by two deformation segments 5241 and a second limiting segment 5242. Both ends of the second limiting segment 5242 are fixedly connected to the deformation segments 5241. The other ends of the two deformation segments 5241 are fixedly connected to the inner wall of the adjusting sleeve 521. The two deformation segments 5241 are concave, the second limiting segment 5242 is convex, and the thickness of the deformation segments 5241 and the second limiting segment 5242 gradually changes from thin to thick from the middle to both sides.

[0048] When the adjusting sleeve 521 slides down in the sliding groove 518, the deformation segment 5241 will contact the outer wall of the first sliding sleeve 516, and the outer wall of the first sliding sleeve 516 will squeeze the deformation segment 5241. Since the middle of the deformation segment 5241 is thin and both ends are thick, when it is subjected to the squeezing force of the first sliding sleeve 516, it will deform inward. While deforming inward, it will pull the second limiting segment 5242 to move towards the inner wall of the adjusting sleeve 521. During the continuous sliding of the adjusting sleeve 521, after the first sliding sleeve 516 squeezes the deformation segment 5241, it will contact the second limiting segment 5242 and squeeze the second limiting segment 5242 to deform until the entire second clamping piece 524 is compressed and deformed between the adjusting sleeve 521 and the first sliding sleeve 516. When the second clamping piece 524 slides into the second clamping groove 513, it will restore its deformation, thereby clamping the adjusting sleeve 521 in the second clamping groove 513 and limiting and fixing the two.

[0049] As Figure 4 and Figure 8 shown, the internal gear ring 53 is fixedly connected to the bottom end of the installation groove 522, and there is an adjustment gap between the inner ring of the internal gear ring 53 and the inner wall of the installation groove 522. An angle marking groove 531 is formed on one side of the internal gear ring 53. The angle marking groove 531 is used to display the included angle between the two connecting bars 545, which is convenient for the staff to adjust the positions of the two workpiece baffles 544.

[0050] As Figure 3 、 Figure 4 、 Figure 9 and Figure 11As shown, the workpiece limiting component 54 includes external racks 541 symmetrically placed in the adjustment gap. The external racks 541 are engaged with the inner ring of the internal gear ring 53. One side of the external rack 541 is fixedly connected with an adjustment limiting piece 542. One end of the adjustment limiting piece 542 is fixedly connected with a connecting bar 545. One end of the connecting bar 545 is fixedly connected with a workpiece baffle 544. A convex strip 543 is fixedly connected to the top of one side of the workpiece baffle 544. An annular adjustment groove 525 adapted to the shape of the adjustment limiting piece 542 is formed at the top of the installation groove 522. The height of the adjustment groove 525 is the sum of the height of the adjustment limiting piece 542 and the height of the connecting bar 545. The height of the external rack 541, the height of the connecting bar 545 are the same as the height of the external rack 541. The height of the installation groove 522 is three times the height of the internal gear ring 53. The bottom end of the workpiece baffle 544 is in an outward-turning structure. An eight-shaped structure is formed between the two workpiece baffles 544. The bottom end of the workpiece baffle 544 is in an outward-turning shape, which can more conveniently allow the two workpiece baffles 544 to be inserted into the side corners of the drone workpiece.

[0051] When it is necessary to limit irregular workpieces, select several side corners according to the shape of the workpiece, so that fixing these side corners can fix the whole workpiece. Judge the angles of the workpiece side corners according to the workpiece drawing, and then adjust the included angle between the two workpiece baffles 544. The included angle between the two workpiece baffles 544 ranges from 10° to 260°. When adjusting the workpiece baffle 544, the staff manually pulls up the workpiece baffle 544 to disconnect the external rack 541 from the connection with the internal gear ring 53 until the adjustment limiting piece 542 moves to the top of the annular adjustment groove 525. Rotate the external rack 541 and judge the angle of the connecting bar 545 at the position of the angle scale groove 531. When it is rotated to the appropriate angle, then press down the external rack 541 to make it snap into the internal gear ring 53 and limit and fix the external rack 541. When the angles of the two workpiece baffles 544 are both adjusted, slide down the adjustment sleeve 521 to drive the two workpiece baffles 544 to move downward. During the movement, the two workpiece baffles 544 in an eight-shaped structure will snap into the side corners of the workpiece, thereby limiting the side corners of the workpiece until the adjustment sleeve 521 slides to be limited and fixed with the first sliding sleeve 516.

[0052] On the other hand, the present invention also provides a cutting system for drone processing, including the cutting device for drone processing described above, and further including a control unit, which is connected to the Y-axis lead screw platform 2, the X-axis lead screw platform 3 and the milling head motor, and is used to control the Y-axis lead screw platform 2 and the X-axis lead screw platform 3 to drive the workpiece operation platform 4 to move in the X-axis and Y-axis directions, and control the milling head motor to drive the vertical milling head to perform cutting processing on the workpiece.

[0053] The working principle of the technical solution provided by the present invention is as follows: when cutting a UAV workpiece, the UAV workpiece to be processed is placed on the workpiece operating platform 4, and the clamping structure 5 is selectively fixed on the clamping holes 41 around the workpiece according to the shape of the workpiece.

[0054] When fixing the clamping structure 5, several side angles are selected according to the shape of the workpiece, so that the workpiece can be fixed as a whole by fixing these side angles, the angle of the workpiece side angle is determined according to the workpiece drawing, and then the angle between the two workpiece baffles 544 is adjusted. When adjusting the workpiece baffle 544, the staff manually pulls the workpiece baffle 544 upward to make the outer rack 541 disengage from the connection with the inner gear ring 53 until the adjustment limit plate 542 moves to the top of the annular adjustment groove 525, rotates the outer rack 541, and determines whether the connecting strip 545 is at an angle. The angle of the mark groove 531 is adjusted. When it is rotated to a suitable angle, the outer rack 541 is pressed downward so that it is inserted into the inner gear ring 53 to limit and fix the outer rack 541. When the angles of the two workpiece baffles 544 are adjusted, the adjusting sleeve 521 is slid downward to drive the two workpiece baffles 544 to move downward. During the movement, the two workpiece baffles 544 in an eight-shaped shape will be inserted into the side angles of the workpiece, thereby limiting the side angles of the workpiece until the adjusting sleeve 521 slides to be limited and fixed with the first sliding sleeve 516.

[0055] When the adjusting sleeve 521 slides down in the sliding groove 518, the deforming section 5241 will contact the outer wall of the first sliding sleeve 516, and the outer wall of the first sliding sleeve 516 will squeeze the deforming section 5241. Since the deforming section 5241 is thin in the middle and thick at both ends, it will deform inward when subjected to the squeezing force of the first sliding sleeve 516, and at the same time, the second limiting section 5242 will be pulled toward the inner wall of the adjusting sleeve 521. Continuing the sliding movement, after the first sliding sleeve 516 squeezes the deformation section 5241, it will contact the second limiting section 5242, squeezing the second limiting section 5242 to deform until the entire second clamping piece 524 is compressed and deformed between the adjusting sleeve 521 and the first sliding sleeve 516. When the second clamping piece 524 slides to the inside of the second clamping groove 513, the deformation is restored, thereby clamping the adjusting sleeve 521 into the second clamping groove 513, and the two are limited and fixed.

[0056] The workpiece is thereby fixed on the workpiece operating platform 4, and then the workpiece processing procedure is carried out. When the workpiece processing is completed and the workpiece to be processed needs to be released from the limit, the adjusting sleeve 521 only needs to be slid up to expose the first rotating column 511 and the second rotating column 512, so as to bend the adjusting sleeve 521 to drive the second rotating column 512 to rotate on the first rotating column 511, so that the workpiece limiting assembly 54 on the adjusting sleeve 521 is offset, thereby releasing the limit on the workpiece.
