Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Such as Figures 1 to 11As shown in the figure, a drilling and milling integrated multi-process CNC drilling machine includes the following embodiments:

[0042] As Figures 1 to 7 shown, Embodiment 1: It includes a workpiece 9, and also includes:

[0043] A processing table 1, a support seat 2 for placing the workpiece 9 is fixedly connected to the top of the processing table 1, and clamping components for fixing the workpiece 9 are arranged on both the left and right sides of the support seat 2;

[0044] Two fitting discs 3 are respectively arranged on both sides of the workpiece 9. Second electric rods 302 are fixedly connected between the two fitting discs 3 and the support seat 2. A plurality of first electric rods 301 are fixedly connected to the side of the fitting disc 3 close to the workpiece 9. The plurality of first electric rods 301 are arranged in a ring around the center of the fitting disc 3. The telescopic ends of the plurality of first electric rods 301 are all fixedly connected with connection frames 401. A connection frame 402 is fixedly connected to one side of the connection frame 401. A through electromagnet 701 is arranged inside the connection frame 401. A fixed cylinder 703 is fixedly connected to one side of the connection frame 402. A connection cylinder 702 is arranged between the through electromagnet 701 and the fixed cylinder 703;

[0045] On the side of the two fitting discs 3 far from the workpiece 9, mounting frames 5 are arranged. A plurality of drill rods 501 for drilling are arranged inside the mounting frames 5. The plurality of drill rods 501 respectively correspond to the plurality of through electromagnets 701 one by one. When the drill rod 501 finishes drilling and contacts the through electromagnet 701, the through electromagnet 701 is energized and magnetically attracted and fixed to the drill rod 501. A transmission member is arranged inside the mounting frame 5 for rotating and drilling the plurality of drill rods 501. A pushing member is arranged on one side of the mounting frame 5.

[0046] During specific implementation, the operator places the workpiece 9 on the top of the support seat 2 and clamps and fixes the workpiece 9 through the clamping component. At the same time, the fitting disc 3 is driven by the second electric rod 302 to fix both ends of the workpiece 9; the pushing member is used to push the drill rod 501 on the mounting frame 5 close to the fitting disc 3, and the transmission member inside the mounting frame 5 drives the plurality of drill rods 501 to rotate, so as to drill the workpiece 9; when the drill rod 501 passes through the workpiece 9, the pushing member continues to push the mounting frame 5, so that the drill rod 501 is inserted into the connection frame 401 and contacts the through electromagnet 701. The through electromagnet 701 is energized and magnetically attracted and fixed to the drill rod 501. The pushing member drives the drill rod 501 to reciprocally pass through the opening on the workpiece 9. The power supply of the through electromagnet 701 can be arranged on the connection cylinder 702. There is no specific limitation on the setting position, as long as it does not affect the implementation of the solution. It drives the through electromagnet 701 to rotate and move along with the drill rod 501, so that the connection cylinder 702 grinds the opening, thereby grinding the inside and both ends of the opening, improving the grinding efficiency.

[0047] As Figures 7 to 8 and Figure 10As shown, in this embodiment, a groove is provided on the side of the through electromagnet 701 close to the workpiece 9. A plurality of first telescopic rods 7010 and a plurality of first springs 7011 are fixedly connected between the through electromagnet 701 and the connecting cylinder 702, and the first springs 7011 are sleeved outside the first telescopic rods 7010.

[0048] A plurality of flow grooves 7022 are provided on the outside of the connecting cylinder 702. A plurality of scraping plates 7021 are arranged inside the connecting cylinder 702. The plurality of scraping plates 7021 are arranged in a ring around the center of the connecting cylinder 702, penetrate through the outside of the connecting cylinder 702 and are slidably connected to the connecting cylinder 702. One end of each of the plurality of scraping plates 7021 is fixedly connected with a connecting plate 7023. A second spring 7024 and a second telescopic rod 7025 are fixedly connected between the connecting plate 7023 and the connecting cylinder 702, and the second spring 7024 is sleeved outside the second telescopic rod 7025.

[0049] During specific implementation, when the two fitting discs 3 move to both sides of the workpiece 9 respectively, by starting the first electric rod 301 on the fitting disc 3, the first electric rod 301 is used to push the connecting frame 401 so that the through electromagnet 701 and the mounting hole on the workpiece 9 are concentric. Then, a plurality of drill rods 501 are driven to rotate and drill holes through a transmission member, and the mounting frame 5 is pushed to move by a pusher, continuously opening mounting holes on the workpiece 9. At this time, the drill rod 501 continues to move, so that the drill rod 501 contacts the through electromagnet 701, a groove is provided on the through electromagnet 701, and the front end of the drill rod 501 can be inserted into the groove to increase the contact with the through electromagnet 701. Then, by energizing the through electromagnet 701, the through electromagnet 701 and the drill rod 501 are magnetically fixed to form a whole. And a first spring 7011 and a first telescopic rod 7010 are fixedly connected between the through electromagnet 701 and the connecting cylinder 702, so that the front end of the drill rod 501 can be smoothly inserted into the groove of the through electromagnet 701; when the pusher drives the mounting frame 5 to push back, at this time the drill rod 501 rotates. Due to the magnetic attraction effect, the drill rod 501 drives the through electromagnet 701 to rotate. When the through electromagnet 701 drives the connecting cylinder 702 into the mounting hole, the connecting cylinder 702 polishes the inside of the mounting hole, directly polishing the hole after drilling, improving the processing efficiency;

[0050] When the connecting cylinder 702 rotates along with the energized electromagnet 701, a plurality of scraping plates 7021 arranged inside the connecting cylinder 702 slide out due to the centrifugal force generated by the rotation of the connecting cylinder 702, causing one end of the scraping plate 7021 to be in close contact with the inner wall of the mounting hole. In cooperation with the rotation of the connecting cylinder 702, the inner wall of the mounting hole is polished. The scraping plate 7021 and the connecting cylinder 702 are fixedly connected through a second spring 7024 and a second telescopic rod 7025, thus ensuring the reset of the scraping plate 7021 after the polishing is completed. Additionally, it can prevent the inner wall of the connecting cylinder 702 from being damaged when the scraping plate 7021 encounters a relatively hard protrusion. The scraping plate 7021 contacts the inner wall of the mounting hole through centrifugal force, and can polish the inside of other mounting holes larger than the aperture of the fixed cylinder 703, achieving the effect of automatic adjustment.

[0051] As Figures 9 to 11 shown, Embodiment 2: A rotating rod 70221 is rotatably connected inside the connecting cylinder 702. A plurality of blowing fan blades 70222 are fixedly connected to the outer side of the rotating rod 70221. A second gear 7028 is fixedly connected to the outer side of the rotating rod 70221. A fixing plate 7026 is rotatably connected to the outer side of the rotating rod 70221. A first gear 7027 is rotatably connected to one side of the fixing plate 7026. The first gear 7027 is meshed with the second gear 7028. An internal gear ring is fixedly connected to the inner side of one end of the connecting cylinder 702. The internal gear ring is meshed with the first gear 7027. A third telescopic rod 7029 and a third spring 7020 are fixedly connected between the fixing plate 7026 and the fixed cylinder 703. The third spring 7020 is sleeved on the outer side of the third telescopic rod 7029.

[0052] During specific implementation, when the energized electromagnet 701 drives the connecting cylinder 702 to rotate, the internal gear ring inside the connecting cylinder 702 drives the first gear 7027 on the fixing plate 7026 to rotate. The first gear 7027 drives the second gear 7028 to rotate. The second gear 7028 drives the fixedly connected rotating rod 70221 to rotate. When the rotating rod 70221 rotates, wind is generated by the rotation of a plurality of externally fixedly connected blowing fan blades 70222 and discharged through a flow channel 7022 opened on the connecting cylinder 702. Thus, in cooperation with the scraping plate 7021 in Embodiment 1, the inner wall of the mounting hole is polished, and the dust on the scraping plate 7021 and the inner wall of the mounting hole is blown out by the wind, preventing the dust from adhering to the inside of the mounting hole and keeping the inside of the mounting hole clean and tidy, achieving the effect of cleaning while polishing.

[0053] In this embodiment, the clamping assembly includes a side support plate 801 fixedly connected to the support base 2. A third electric rod 802 is fixedly connected to one side of the side support plate 801. A clamping plate 803 for fixing the workpiece 9 is fixedly connected to the telescopic end of the third electric rod 802.

[0054] Both sides of the two side support plates 801 are fixedly connected with dust suction ports 804. Dust suction devices 805 are arranged on one side of each of the two side support plates 801. The suction ends of the dust suction devices 805 are fixedly communicated with the two dust suction ports 804 respectively, and are used for absorbing the dust generated by drilling.

[0055] During specific implementation, when a large amount of dust is generated during continuous drilling, the dust suction device 805 is installed on the top of the processing table 1. By starting the dust suction device 805, the dust suction ports 804 on both sides of the side support plate 801 perform dust suction. When the dust generated during the drilling attempt is adsorbed by the dust suction port 804, and when the dust generated during the grinding of the scraping plate 7021, the wind generated by the rotation of the rotating rod 70221 moves the dust, so that the dust is blown out from the installation hole and then absorbed by the dust suction port 804, avoiding the need for other equipment to clean the installation hole after drilling.

[0056] As Figure 9 and Figure 10 As shown, Embodiment 3: An extrusion plate 7032 is arranged inside the fixed cylinder 703. A reciprocating lead screw 7031 is connected inside the extrusion plate 7032 through a ball screw pair. A fourth telescopic rod 7037 is fixedly connected between the extrusion plate 7032 and the connecting frame 402. The reciprocating lead screw 7031 rotates on one side of the connecting frame 402. The reciprocating lead screw 7031 penetrates through the fixed cylinder 703 and is rotatably connected with the fixed cylinder 703. One end of the rotating rod 70221 extends into the reciprocating lead screw 7031. A limiting groove 7030 is formed on the outer side of the rotating rod 70221. A convex block is fixedly connected inside the reciprocating lead screw 7031 and extends into the limiting groove 7030 and is slidably connected with the rotating rod 70221. An air bag 7033 is sleeved on the outer side of the reciprocating lead screw 7031. Both ends of the air bag 7033 are fixedly connected with the extrusion plate 7032 and the fixed cylinder 703 respectively. An annular plate 7034 is fixedly connected to the outer side of the fixing plate 7026. A communication frame 7035 is fixedly connected to the annular plate 7034 close to the connecting cylinder 702. A plurality of dust blowing heads are arranged on the outer side of the communication frame 7035. A plurality of air outlet pipes 7036 are fixedly communicated between the air bag 7033 and the communication frame 7035. An air suction pipe is arranged on the outer side of the air bag 7033. A one-way intake valve is arranged on the outer side of the air suction pipe. A one-way exhaust valve is arranged on the outer side of the air outlet pipe 7036.

[0057] During specific implementation, when the rotating rod 70221 rotates, the reciprocating lead screw 7031 is driven to rotate through the limiting groove 7030 formed on the outer side of the rotating rod 70221. When the reciprocating lead screw 7031 rotates, the pressing plate 7032 connected to the outer side through a ball screw pair is driven. When the pressing plate 7032 moves reciprocally, the pressing plate 7032 presses the airbag 7033, so that the gas inside the airbag 7033 is conveyed to the connecting frame 7035 through the air outlet pipe 7036, and air is blown into the connecting cylinder 702 through the dust blowing head on the connecting frame 7035. First, it can accelerate the flow of gas when the rotating rod 70221 rotates. Second, it can blow out the dust that can fall into the connecting cylinder 702 to ensure the cleanliness inside the connecting cylinder 702.

[0058] As Figure 5 shown, Embodiment 4: The transmission member includes a driving gear 503 rotatably connected inside the mounting frame 5. A plurality of driven gears 502 are meshed and connected to the outer side of the driving gear 503. The plurality of driven gears 502 are respectively fixedly connected to a plurality of drill rods 501. The drill rods 501 are rotatably connected to the mounting frame 5. A driving motor 504 is fixedly connected to the outer side of the mounting frame 5. The output shaft of the driving motor 504 penetrates through the mounting frame 5 and is fixedly connected to the driving gear 503.

[0059] During specific implementation, the output shaft of the driving motor 504 drives the driving gear 503 to rotate. The driving gear 503 drives the plurality of driven gears 502 to rotate, and then drives the drill rods 501 to rotate, so as to drill the workpiece 9.

[0060] The pushing member includes a pushing frame 6 fixedly connected to one side of the mounting frame 5. A hydraulic telescopic cylinder 7 is arranged on one side of the pushing frame 6. The hydraulic telescopic cylinder 7 is fixedly connected to the top of the processing table 1. The telescopic end of the hydraulic telescopic cylinder 7 is fixedly connected to the pushing frame 6.

[0061] During specific implementation, by starting the hydraulic telescopic cylinder 7, the hydraulic telescopic cylinder 7 pushes the pushing frame 6 to move. The pushing frame 6 drives the mounting frame 5 to move, and then the drill rods 501 on the mounting frame 5 continuously drill and feed.

[0062] A method for drilling and milling a workpiece is also provided, including the following steps:

[0063] S1. The operator places the workpiece 9 on the top of the support base 2, and clamps and fixes the workpiece 9 through the clamping assembly. At the same time, the second electric rod 302 drives the fitting disc 3 to fix both ends of the workpiece 9.

[0064] S2. The pushing member is used to push the drill rods 501 on the mounting frame 5 close to the fitting disc 3, and the transmission member inside the mounting frame 5 drives the plurality of drill rods 501 to rotate, so as to drill the workpiece 9.

[0065] S3.
