The plurality of drill rods 501 correspond to a plurality of electromagnets 701 respectively. When the drill rods 501 drill holes, they come into contact with the electromagnets 701. The electromagnets 701 are energized and fixed to the drill rods 501 by magnetic attraction. A transmission part is provided inside the mounting frame 5 for rotating the plurality of drill rods 501 for drilling holes, and a pushing part is provided on one side of the mounting frame 5.

[0025] During the 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 assembly, and at the same time drives the bonding plate 3 through the second electric rod 302 to fix the two ends of the workpiece 9; pushes the drill rod 501 on the installation frame 5 to approach the bonding plate 3 through the pushing member, and drives the multiple drill rods 501 to rotate through the transmission member inside the installation frame 5, so as to drill holes in the workpiece 9; after the drill rod 501 passes through the workpiece 9, the pushing member continues to push the installation frame 5, so that the drill rod 501 is inserted into the connecting frame 4 01, and contacts with the electromagnet 701. The electromagnet 701 is energized and fixed with the drill rod 501 by magnetic attraction. The pusher drives the drill rod 501 to reciprocate through the opening on the workpiece 9. The power supply of the electromagnet 701 can be set on the connecting tube 702. There is no specific limitation on the setting position, which does not affect the implementation of the plan. The electromagnet 701 is driven to rotate and move with the drill rod 501, so that the connecting tube 702 grinds the opening, thereby grinding the inside and both ends of the opening, thereby improving the grinding efficiency.

[0026] like Figures 7 and 8 and Fig.10 As shown, in this embodiment, a groove is provided on the side of the electromagnet 701 close to the workpiece 9 , and a plurality of first telescopic rods 7010 and a plurality of first springs 7011 are fixedly connected between the electromagnet 701 and the connecting tube 702 , and the first springs 7011 are sleeved on the outside of the first telescopic rods 7010 .

[0027] A plurality of flow grooves 7022 are provided on the outside of the connecting tube 702, and a plurality of scrapers 7021 are provided inside the connecting tube 702. The plurality of scrapers 7021 are arranged in a ring shape around the center of the connecting tube 702, and pass through the outside of the connecting tube 702 and are slidably connected to the connecting tube 702. A connecting plate 7023 is fixedly connected at one end of the plurality of scrapers 7021, and a second spring 7024 and a second telescopic rod 7025 are fixedly connected between the connecting plate 7023 and the connecting tube 702, and the second spring 7024 is sleeved on the outside of the second telescopic rod 7025.

[0028] In specific implementation, when the two bonding disks 3 are moved to the two sides of the workpiece 9 respectively, the first electric rod 301 on the bonding disk 3 is started, so that the first electric rod 301 pushes the connecting frame 401 to make the electromagnet 701 and the mounting hole on the workpiece 9 coincide with each other in the circle center, and then the multiple drill rods 501 are driven by the transmission member to rotate and drill holes, and the installation frame 5 is pushed to move by the pushing member to continuously open the installation holes on the workpiece 9. At this time, the drill rod 501 continues to move, so that the drill rod 501 contacts the electromagnet 701, so that the electromagnet 701 is provided with a groove, so that the front end of the drill rod 501 can be inserted into the groove, thereby increasing the contact with the electromagnet 701, and then the electromagnet 701 is moved. When power is turned on, the electromagnet 701 is magnetically fixed to the drill rod 501, forming a whole with the drill rod 501, and a first spring 7011 and a first telescopic rod 7010 are fixedly connected between the electromagnet 701 and the connecting tube 702, so that the front end of the drill rod 501 can be smoothly inserted into the groove of the electromagnet 701; when the pusher drives the installation frame 5 to push back, the drill rod 501 rotates at this time, and due to the effect of magnetic attraction, the drill rod 501 drives the electromagnet 701 to rotate. When the electromagnet 701 drives the connecting tube 702 to enter the interior of the installation hole, the connecting tube 702 grinds the interior of the installation hole, and the hole is directly grinded after drilling, thereby improving the processing efficiency; When the connecting tube 702 rotates with the electromagnet 701, the multiple scrapers 7021 arranged inside the connecting tube 702 slide out with the centrifugal force of the rotation of the connecting tube 702, so that one end of the scraper 7021 fits and contacts with the inner wall of the mounting hole, and the inner wall of the mounting hole is polished with the rotation of the connecting tube 702. The scraper 7021 and the connecting tube 702 are fixedly connected by the second spring 7024 and the second telescopic rod 7025, thereby ensuring the reset of the scraper 7021 after the polishing is completed, and preventing the scraper 7021 from damaging the inner wall of the connecting tube 702 when it hits a harder protrusion. The scraper 7021 contacts the inner wall of the mounting hole through centrifugal force, and can polish the inside of other mounting holes that are larger than the aperture of the fixed tube 703, thereby achieving an automatic adjustment effect.

[0029] like Figures 9 to 11As shown, embodiment 2: a rotating rod 70221 is rotatably connected inside the connecting tube 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 fixed 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 fixed plate 7026, the first gear 7027 is meshingly connected to the second gear 7028, an inner gear ring is fixedly connected to the inner side of one end of the connecting tube 702, the inner gear ring is meshingly connected to the first gear 7027, a third telescopic rod 7029 and a third spring 7020 are fixedly connected between the fixed plate 7026 and the fixed tube 703, and the third spring 7020 is sleeved on the outer side of the third telescopic rod 7029.

[0030] In specific implementation, when the electromagnet 701 drives the connecting tube 702 to rotate, the inner gear ring inside the connecting tube 702 drives the first gear 7027 on the fixed plate 7026 to rotate, the first gear 7027 drives the second gear 7028 to rotate, and the second gear 7028 drives the fixedly connected rotating rod 70221 to rotate. When the rotating rod 70221 rotates, multiple blowing fan blades 70222 fixedly connected to the outside rotate to generate wind force, which is discharged through the circulation groove 7022 opened on the connecting tube 702, so as to cooperate with the scraper 7021 in Example 1 to grind the inner wall of the mounting hole, and blow out the dust on the scraper 7021 and the inner wall of the mounting hole by wind force, so as to prevent dust from adhering to the inside of the mounting hole, and make the inside of the mounting hole clean and tidy, so as to achieve the effect of grinding and cleaning at the same time.

[0031] In this example, the clamping assembly includes a side support plate 801 fixedly connected to the support seat 2, a third electric rod 802 is fixedly connected to one side of the side support plate 801, and a clamping plate 803 for fixing the workpiece 9 is fixedly connected to the telescopic end of the third electric rod 802.

[0032] Dust suction ports 804 are fixedly connected to both sides of the two side support plates 801, and dust suction devices 805 are provided on one side of the two side support plates 801. The suction ends of the dust suction devices 805 are fixedly connected to the two dust suction ports 804 respectively for absorbing dust from drilling.

[0033] During specific implementation, a large amount of dust will be generated when drilling continuously. 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 are used to suction dust. The dust from the drilling attempt will be absorbed by the dust suction ports 804, and the dust generated when the scraper 7021 is grinding will be moved by the wind force generated by the rotation of the rotating rod 70221, so that the dust is blown out of 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.

[0035] In specific implementation, when the rotating rod 70221 rotates, the reciprocating screw rod 7031 is driven to rotate through the limiting groove 7030 opened on the outer side of the rotating rod 70221. When the reciprocating screw rod 7031 rotates, it drives the extrusion plate 7032 connected to the outer side through the ball nut pair. When the extrusion plate 7032 moves back and forth, the extrusion plate 7032 squeezes the airbag 7033, so that the gas inside the airbag 7033 is transported to the connecting frame 7035 through the air outlet pipe 7036, and air is blown into the inside of the connecting tube 702 through the dust blowing head on the connecting frame 7035.
