[0023] The drilling assembly 54 comprises four second motors 541 fixedly connected to the bottom of the inner wall of the drilling frame 4, the output ends of the second motors 541 are fixedly connected with second rotating shafts 542, the bottom of each second rotating shaft 542 is fixedly connected with a circular plate 543, and the bottom of the circular plate 543 is fixedly connected with a drill rod 544.

[0024] The bottom of the drilling frame 4 is fixedly connected with extrusion rods 548 on both sides, the outer wall of the bearing table 53 is fixedly connected with four bearing shells 545, the top of each bearing shell 545 is provided with a rhombic hole 546, and the top of each bearing shell 545 carries a workpiece 547.

[0025] By adopting the above scheme, the first motor 51 is started, the first motor 51 drives the first rotating shaft 52 and the bearing table 53 to rotate, the bearing table 53 drives the bearing shell 545 and the workpiece 547 to rotate to the bottom of the drill rod 544. After the first motor 51 is turned off, the hydraulic machine 3 and the second motor 541 are started. The second motor 541 drives the second rotating shaft 542 and the circular plate 543 to rotate, the circular plate 543 drives the drill rod 544 to rotate; at the same time, the hydraulic machine 3 drives the drilling frame 4 and the second motor 541 to descend synchronously. The drill rod 544 in the drilling assembly 54 rotates and descends, and the top of the workpiece 547 is drilled.

[0026] The top of the bearing shell 545 is provided with a clamping assembly 55, the clamping assembly 55 comprises special-shaped shells 551 fixedly connected to the top of the bearing shell 545 on both sides, the top of each special-shaped shell 551 is provided with a circular hole 552, and the inner wall top end of each special-shaped shell 551 is slidably connected with a lifting plate 553.

[0028] The end, away from the sliding block 556, of the connecting barrel 557 is fixedly connected with a special-shaped plate 558, the special-shaped plate 558 is arranged outside the special-shaped shell 551, the side center of the special-shaped plate 558 penetrates and is slidably connected with an elastic sliding rod 559, one end of the elastic sliding rod 559 is fixedly connected with a flexible clamping block 5510, and one side of the flexible clamping block 5510 is in contact with the side wall of the workpiece 547.

[0029] When the drilling frame 4 is lowered, the extrusion rod 548 is lowered together. The extrusion rod 548 passes through the round hole 552 during the lowering process, contacts the lifting plate 553 in the special-shaped shell 551, and exerts a downward pressure on the lifting plate 553, which is in contact with the drill rod 544 and the workpiece 547. At this time, the lifting plate 553 drives the rotating rod 554 to descend, and the rotating rod 554 further drives the sliding block 556 to slide along the outer wall of the cross rod 555, and the sliding block 556 drives the connecting cylinder 557 and the special-shaped plate 558 to move. The special-shaped plate 558 drives the elastic sliding rod 559 and the flexible clamp block 5510 to move together. Since the outer wall of the workpiece 547 is rhombic, the side wall of the flexible clamp block 5510 can closely fit the side wall of the workpiece 547 during the movement.

[0030] As shown in Figures 1 to 11 The bottom of the lifting plate 553 is provided with an auxiliary assembly 56, which includes a vertical rod 561 fixedly connected at the center of the bottom of the lifting plate 553. The bottom of the lifting plate 553 is fixedly connected with a first extrusion spring 562 near the vertical rod 561. The bottom of the first extrusion spring 562 is fixedly connected to the inner wall of the bottom of the special-shaped shell 551. The bottom of the vertical rod 561 is fixedly connected with a piston plate 563.

[0031] The outer wall of the piston plate 563 is slidably connected with a liquid storage shell 564. The bottom of the liquid storage shell 564 is fixedly connected to the inner wall of the bottom of the bearing shell 545. The top end of the liquid storage shell 564 is communicated with three bend pipes 565. The top of the bearing shell 545 is provided with six positioning holes 566. The inner wall of the bottom end of the positioning hole 566 is fixedly connected with a fixed ring 567. The inner wall of the fixed ring 567 is fixedly connected with a suction disc 568. The bottom end of the suction disc 568 is communicated with the top end of the bend pipe 565.

[0032] The above scheme is adopted: when the lifting plate 553 is lowered, it drives the vertical rod 561 and the piston plate 563 to descend together. When the piston plate 563 descends in the liquid storage shell 564, a negative pressure is generated in the rod area of the liquid storage shell 564. The negative pressure enters the inside of the suction disc 568 through the bend pipe 565, thereby adsorbing the bottom outer wall of the workpiece 547.

[0033] The bottom end of the liquid storage shell 564 is communicated with a circular pipe 5611. The two circular pipes 5611 are communicated with a special-shaped cylinder 5612. The bottom of the special-shaped cylinder 5612 is fixedly connected to the inner wall of the bottom of the bearing shell 545. The inner wall of the special-shaped cylinder 5612 is slidably connected with a lifting frame rod 5613. The bottom end of the lifting frame rod 5613 is fixedly connected with a second extrusion spring 5615. The top of the second extrusion spring 5615 is fixedly connected to the inner wall of the top of the special-shaped cylinder 5612. The top of the lifting frame rod 5613 is fixedly connected with a flexible plate 5614.

[0034] Adopting the above scheme: when the piston plate 563 descends inside the liquid storage shell 564, the cooling liquid in the rodless area of the liquid storage shell 564 enters inside the circular tube 5611 and flows into the special-shaped cylinder 5612 through the circular tube 5611. After the cooling liquid enters the special-shaped cylinder 5612, the lifting frame rod 5613 is first vertically lifted inside the special-shaped cylinder 5612. The lifting frame rod 5613 drives the flexible plate 5614 to lift, and the flexible plate 5614 will contact the bottom center of the workpiece 547 when lifting, thereby lifting the bottom of the workpiece 547.

[0035] The flexible plate 5614 is arranged outside the special-shaped cylinder 5612, four iron pipes 5616 are communicated around the end of the special-shaped cylinder 5612, one end of the iron pipe 5616 away from the special-shaped cylinder 5612 is communicated with the liquid discharge element 5617, the side of the liquid storage shell 564 away from the circular tube 5611 is communicated with the one-way valve pipe 5618, the one-way valve pipe 5618 can inject the cooling liquid outside into the inside of the liquid storage shell 564, and the one-way valve pipe 5618 can only inject the liquid into the inside of the liquid storage shell 564, the cooling liquid inside the liquid storage shell 564 cannot flow to the outside through the one-way valve pipe 5618, one end of the one-way valve pipe 5618 penetrates the bearing shell 545 and extends to the outside of the bearing shell 545, the bottom of the bearing shell 545 is provided with the discharge port 5619 on both sides, and the discharge port 5619 is arranged to facilitate the discharge of the cooling liquid and iron filings generated during drilling inside the bearing shell 545.

[0036] Adopting the above scheme: when the lifting frame rod 5613 bottom end moves to the iron pipe 5616, the cooling liquid enters the inside of the iron pipe 5616 and flows into the liquid discharge element 5617 through the iron pipe 5616. Then, the cooling liquid cools the falling drill rod 544.

[0037] The working principle and use process of the present application are as follows: The worker places the workpiece 547 on the top of the bearing shell 545, which is slightly clamped by the two flexible clamping blocks 5510, so that the workpiece 547 is positioned at the top center of the bearing shell 545. The first motor 51 is started to drive the first rotating shaft 52 and the bearing table 53 to rotate, and the bearing table 53 drives the bearing shell 545 and the workpiece 547 to rotate to the bottom of the drill rod 544. When the first motor 51 is turned off, the hydraulic machine 3 and the second motor 541 are started. The second motor 541 drives the second rotating shaft 542 and the circular plate 543 to rotate, and the circular plate 543 drives the drill rod 544 to rotate. The hydraulic machine 3 drives the drill holder 4 and the second motor 541 to descend, and the second motor 541 drives the drill rod 544 in the drill assembly 54 to rotate and descend. The drill rod 544 can drill holes in the top of the workpiece 547 during the descending process, thereby quickly drilling the workpiece 547. When the drill holder 4 descends, the drill holder 4 drives the extrusion rod 548 to descend. The extrusion rod 548 descends and contacts the lifting plate 553 in the special-shaped shell 551 through the circular hole 552, thereby pressing the lifting plate 553 downward. Before the drill rod 544 and the workpiece 547 contact, the lifting plate 553 drives the rotating rod 554 to descend. The rotating rod 554 drives the sliding block 556 to slide along the outer wall of the cross rod 555. The sliding block 556 drives the connecting cylinder 557 and the special-shaped plate 558 to move. The special-shaped plate 558 drives the elastic sliding rod 559 and the flexible clamping block 5510 to move. Since the outer wall of the workpiece 547 is rhombic, the side wall of the flexible clamping block 5510 can closely fit the side wall of the workpiece 547 during the moving process, thereby accurately positioning the workpiece 547 at the top center of the bearing shell 545. This prevents the workpiece 547 from shifting during processing, and further improves the stability and accuracy of drilling.

[0038] When the lifting plate 553 descends, the lifting plate 553 drives the vertical rod 561 and the piston plate 563 to descend. When the piston plate 563 descends in the liquid storage shell 564, a negative pressure is generated in the rod area of the liquid storage shell 564. The negative pressure enters the inner part of the elbow pipe 565, and then enters the inner part of the suction cup 568 through the elbow pipe 565, thereby adsorbing the bottom outer wall of the workpiece 547. The suction force of the suction cup 568 can stably adsorb the workpiece 547 on the top of the bearing shell 545, thereby preventing the drill rod 544 from generating excessive downward pressure when drilling the center of the workpiece 547. This reduces the warping of the outer wall of the workpiece 547, and ensures the quality of the final product. Since the side of the flexible clamping block 5510 close to the workpiece 547 is inclined, and the top end of the flexible clamping block 5510 is wider than the bottom end, the two flexible clamping blocks 5510 can further prevent the two sides of the workpiece 547 from warping during clamping, thereby improving the processing accuracy of the workpiece 547.

[0039] When the piston plate 563 descends inside the liquid storage shell 564, the cooling liquid inside the rodless area in the liquid storage shell 564 enters the inside of the circular pipe 5611, and the cooling liquid enters the inside of the special-shaped cylinder 5612 through the circular pipe 5611. After the cooling liquid enters the inside of the special-shaped cylinder 5612, the lifting frame rod 5613 will first vertically move upwards in the inside of the special-shaped cylinder 5612, and the lifting frame rod 5613 drives the flexible plate 5614 to move upwards. The flexible plate 5614 will contact the bottom center of the workpiece 547 during the upward movement of the flexible plate 5614, lift the bottom of the workpiece 547, prevent the center of the workpiece 547 from being concave during the drilling of the plurality of drill rods 544, ensure the accuracy during drilling, reduce shape distortion, and improve the accuracy of drilling. When the bottom end of the lifting frame rod 5613 moves to the iron pipe 5616, the cooling liquid enters the inside of the iron pipe 5616, and the cooling liquid enters the inside of the liquid discharge piece 5617 through the iron pipe 5616. Then the falling drill rod 544 is cooled, which improves the subsequent drilling efficiency of the drill rod 544, and the sprayed cooling liquid can clean the iron filings adhered to the outer wall of the drill rod 544. Cleaning the iron filings helps to maintain the cutting performance of the drill rod 544 and maintain high processing speed.
