[0019] This utility model provides the following technical solution:

[0020] Example 1, please refer to Figures 1 to 5 :

[0021] A multi-hole cylinder rotary drilling machine includes a bed 1. Load-bearing plates 2 are fixedly connected to the left and right sides of the bottom of the bed 1. A support plate 3 is provided on the top left side of the bed 1, and a mounting plate 4 is fixedly connected to the top right side of the support plate 3. A cylinder 5 is mounted on the mounting plate 4, and a traction plate 6 is fixedly connected to the power end of the cylinder 5. A multi-spindle drill 7 is provided at the bottom of the traction plate 6, which facilitates multi-faceted adjustment of the drilling process. A cylinder 9 is provided on the top right side of the bed 1, and a turntable 10 is provided at the top of the inner cavity of the cylinder 9. The turntable 10 has five storage slots 11, which facilitates the simultaneous clamping of five workpieces. The turntable 10 has a fixed groove 12 at the top center. The outer wall of the fixed groove 12 has a through groove 13 that communicates with five storage grooves 11. The inner cavity of the through groove 13 is fixedly connected to a fixed plate 25. The inner cavity of the fixed groove 12 is equipped with a clamping mechanism. The bottom of the inner cavity of the fixed groove 12 has a square hole 14. A square tube 15 that is compatible with it slides through the inner cavity of the square hole 14. Through the sliding fit between the square tube 15 and the square hole 14, the rotation of the square tube 15 can drive the turntable 10 to rotate synchronously. The bottom end of the square tube 15 is equipped with a stretching and rotating mechanism. The top end of the square tube 15 is fixedly connected to a cylinder 23. The right side of the cylinder 9 is equipped with a pushing mechanism.

[0022] The clamping mechanism includes an arc-shaped clamping plate 28, which is located in the inner cavity of the fixed slot 12. A connecting rod 26 is fixedly connected to the back side of the arc-shaped clamping plate 28. A through hole adapted to the connecting rod 26 is opened on the fixed plate 25, and the other end of the connecting rod 26 passes through the inner cavity of the through hole and is fixedly connected to a passive arc-shaped moving block 27. A compression spring 29 is sleeved on the outside of the connecting rod 26, and the two ends of the compression spring 29 are fixedly connected to the passive arc-shaped moving block 27 and the fixed plate 25, respectively. An active arc-shaped moving block 24 corresponding to the passive arc-shaped moving block 27 is fixedly connected to the outer wall of the cylinder 23. When five workpieces are simultaneously placed into the inner cavities of the five placement slots 11, the cylinder 23 moves vertically downward and drives the active arc-shaped moving block 24 to compress the adjacent passive arc-shaped moving block 27 to overcome the resistance of the compression spring 29 and move horizontally. This allows the arc-shaped clamping plate 28 to clamp and fix the workpieces, improving drilling stability and drilling quality.

[0023] The stretching and rotating mechanism includes two first electro-hydraulic actuators 16, which are respectively located at the bottom of the inner cavity of the cylinder 9 near the left and right sides. The power ends of the two first electro-hydraulic actuators 16 are fixedly connected to the same first annular plate 17, and the inner cavity of the first annular plate 17 is rotatably connected to a limiting disk 18. The bottom end of the square tube 15 passes through the center of the limiting disk 18 and extends to the bottom of the first annular plate 17. A matching square post 19 is slidably inserted into the bottom end of the inner cavity of the square tube 15, and the bottom end of the square post 19 is rotatably connected to the bottom of the inner cavity of the cylinder 9. A first servo motor 20 is provided at the bottom of the inner cavity of the cylinder 9. The power end of the 0 is fixedly connected to a transmission gear 21. A driven gear 22 meshes with the left side of the transmission gear 21, and the driven gear 22 is sleeved and fixed on the outer wall of the square column 19. By activating the first electro-hydraulic push rod 16, the first annular plate 17 is pulled vertically downward. The downward movement of the first annular plate 17 drives the square tube 15 to move vertically downward through the limiting plate 18, and pulls the cylinder 23 to move vertically downward, thereby realizing the automated clamping of the workpiece. Subsequently, by activating the first servo motor 20, the square column 19 is driven to rotate. The rotation of the square column 19 drives the turntable 10 to rotate, thereby driving the workpiece to rotate. This enables five stations to work simultaneously, improving processing efficiency.

[0024] Working Principle: In use, this invention first places five workpieces to be processed into the inner cavities of five storage slots 11. Then, the first electro-hydraulic actuator 16 is activated, pulling the first annular plate 17 downwards. This downward movement of the annular plate 17 causes the square tube 15 to slide downwards, which in turn causes the cylinder 23 to move vertically downwards. The active arc-shaped moving block 24 pushes the passive arc-shaped moving block 27 horizontally, thereby causing the arc-shaped clamping plate 28 to clamp the workpieces via the connecting rod 26. Subsequently, the first servo motor 20 is activated, driving the transmission gear 21 to rotate. The rotation of the transmission gear 21 drives the driven gear 22 to rotate, which in turn drives the square column 19 to rotate. The rotation of the square column 19 drives the square tube 15 to rotate, which in turn drives the turntable 10 to rotate. This allows the positions of the five workpieces to be interchanged, enabling simultaneous five-station processing, which improves processing efficiency. By employing CNC drilling technology, when the side edge of the drill-milling cutter contacts the outer surface of the planar part, the cutter's entry and exit points should be along the extension line of the valve seat contour curve. Appropriate entry and exit programs can be programmed to avoid tool marks, reduce tool contact marks, and ensure the surface quality of the bearing cylinder bore. Path compensation technology is used, analyzing the tool path during tool movement using a finite element model and adjusting it according to the deformation amount to compensate for the tool deflection caused by deformation during entry. This allows residual material to be removed in a single pass while ensuring machining quality. Continuous automatic cutting technology is employed, utilizing cylinder 5 to control the continuity of automatic milling of the contour curve, thus avoiding pauses during workpiece drilling feed and preventing elastic deformation problems in the hole position, fixture, and machine tool process system. This promotes the balance of the integrated machining process for multi-hole cylinders and improves the drilling quality of multi-hole cylinders.

[0025] Example 2, please refer to Figure 1 and Figure 2 :

[0026] Each fixed groove 12 has a circular slot 41 at the bottom of its inner cavity, and a matching circular plate 30 is provided in the inner cavity of the circular slot 41. A vertical rod 31 is fixedly connected to the bottom of each circular plate 30, and the same second annular plate 32 is fixedly connected to the bottom end of each vertical rod 31. Fixed rods 43 are fixedly connected to the left and right sides of the bottom of the turntable 10, and trays 44 are fixedly connected to the bottom ends of the fixed rods 43. A second electro-hydraulic push rod 33 is provided on the top of each of the two trays 44, and the power end of the second electro-hydraulic push rod 33 is fixedly connected to the second annular plate 32. The second electro-hydraulic push rod 33 drives the vertical lifting and lowering of the second annular plate 32, thereby adjusting the height of the workpiece placed in the inner cavity of the storage groove 11. When the circular plate 30 is located in the inner cavity of the circular slot 41, the arc-shaped clamping plate 28 can easily clamp and fix the workpiece. When the circular plate 30 is raised and the workpiece is flush with the top of the turntable 10, the processed workpiece can be automatically pushed out.

[0027] The feeding mechanism includes a horizontal plate 34, which is fixedly connected to the right side of the cylinder 9. A third electro-hydraulic push rod 35 is provided on the top of the horizontal plate 34, and a lifting plate 36 is fixedly connected to the power end of the third electro-hydraulic push rod 35. A bearing is provided on the lifting plate 36, and a square-hole tube 37 is rotatably connected to the inner cavity of the bearing. A matching square rod 39 is slidably inserted into the bottom end of the inner cavity of the square-hole tube 37. A second servo motor 40 is provided on the top left side of the horizontal plate 34, and the bottom end of the square rod 39 is fixedly connected to the power end of the second servo motor 40. An arc-shaped feeding plate 3 is fixedly connected to the front top end of the square-hole tube 37. 8. A rubber pad 8 is provided on the front side of the arc-shaped pusher plate 38. A platform 42 is fixedly connected to the top right front side of the cylinder 9. By starting the third electro-hydraulic push rod 35, the lifting plate 36 is pulled vertically downward, which can drive the arc-shaped pusher plate 38 to approach the workpiece. When the second servo motor 40 is started and drives the square rod 39 to rotate, the square rod 39 drives the square hole tube 37 to rotate. The rotation of the square hole tube 37 drives the arc-shaped pusher plate 38 to rotate, which can push the workpiece on the turntable 10 to the top of the platform 42. This makes it convenient for the staff to collect the workpiece intermittently, and at the same time, it will not affect the subsequent processing.

[0028] Working principle: When the workpiece is processed, the second electro-hydraulic push rod 33 is activated to push the second annular plate 32 upward. The upward movement of the second annular plate 32 pushes the circular plate 30 upward through the vertical rod 31, and drives the workpiece upward, so that the bottom of the workpiece is flush with the top of the turntable 10. Then, the third electro-hydraulic push rod 35 is activated to pull the lifting plate 36 vertically downward, which can drive the arc-shaped pusher plate 38 to approach the workpiece. When the second servo motor 40 is activated and drives the square rod 39 to rotate, the square rod 39 drives the square hole round tube 37 to rotate. The rotation of the square hole round tube 37 drives the arc-shaped pusher plate 38 to rotate, thereby pushing the workpiece on the turntable 10 to the top of the platform 42. Through cyclic operation, the next four workpieces can be pushed onto the platform 42 in sequence, which makes it convenient for the staff to collect the workpieces intermittently, and at the same time, it will not affect the subsequent processing.
