[0043] Directions:

[0044] First, place the ductile iron casting on the core support plate 1, ensuring that it is between the four clamping arms 19. Then, the user controls the electric secondary telescopic rod 20 to extend and retract it. When the electric secondary telescopic rod 20 is shortened, it will push the sliding cylinder 8 to slide on the core fixed block 7. The sliding of the sliding cylinder 8 drives the rack 9 to move, and since the rack 9 is meshed with the middle core gear 5, the middle core gear 5 is driven to rotate. The rotation of the middle core gear 5 drives the racks 9 of the other three reciprocating clamping mechanisms 6 to move, so that the other three sliding cylinders 8 also slide on their respective core fixed blocks 7. The meshing of the rack 9 with the middle core gear 5 causes the middle core gear 5 to rotate, and with the help of the linkage effect of the gears, the clamping arms 19 of the other three reciprocating clamping mechanisms 6 are driven to move synchronously, thereby achieving uniform and stable clamping of the ductile iron casting.

[0045] The structure of the device has a good buffering effect. Sliding guide strips 11 are fixedly provided on two opposite inner walls of the rectangular frame housing 10, and the extending direction thereof is parallel to the extending direction of the rectangular frame housing 10. Auxiliary sliding blocks 12 are slidably provided on the two symmetrically arranged sliding guide strips 11, and the two sides of the auxiliary sliding block 12 are slidably matched with the two symmetrically arranged sliding guide strips 11. A buffer rod body 13 is provided on the auxiliary sliding block 12, and the extending direction of the buffer rod body 13 is also parallel to the extending direction of the rectangular frame housing 10, and one end thereof passes through one end of the rectangular frame housing 10. An inner spring 14 is provided at one end of the auxiliary sliding block 12, and the other end of the inner spring 14 abuts against one end of the rectangular frame housing 10; an outer spring 15 is provided at the other end of the auxiliary sliding block 12, and the other end of the outer spring 15 abuts against the other end of the rectangular frame housing 10, and the outer spring 15 covers the buffer rod body 13. A U-shaped sliding plate 16 is fixedly provided at one end of the outer side of the buffer rod body 13, and one end of the outer side of the buffer rod body 13 is fixedly connected to the inner side of the back of the U-shaped sliding plate body 16. Sliding guide grooves 17 are symmetrically provided on both sides of the outer side of the rectangular frame shell 10, and the two side wings 18 of the U-shaped sliding plate body 16 slide and cooperate with the sliding guide grooves 17. Such a structure can ensure the stability and safety of the clamping of the ductile iron casting and avoid damage to the ductile iron casting. During the clamping process, the inner spring 14 and the outer spring 15 on the auxiliary sliding block 12 and the buffer rod body 13 jointly play the role of buffering and adjusting the clamping force, effectively avoiding damage to the ductile iron casting. When the ductile iron casting needs to be loosened, the user controls the electric secondary telescopic rod 20 to extend, driving the sliding column 8 to slide in the opposite direction, so that the clamping arm 19 is away from the ductile iron casting, thereby achieving the purpose of loosening the ductile iron casting.

[0046] Stable and efficient clamping: The ductile iron casting can be clamped evenly and stably through the coordinated action of the four reciprocating clamping mechanisms 6 and the meshing of the rack 9 and the central core gear 5. Regardless of the shape and size of the ductile iron casting, it can ensure that there will be no displacement during the punching process, thus improving the accuracy and quality of the punching.

[0047] The synchronous movement of the four clamping arms 19 makes the clamping force distribution more uniform, thus avoiding damage to the ductile iron casting due to excessive local force.

[0048] Good buffering protection performance: the cooperation between the sliding guide strip 11 and the auxiliary sliding block 12 in the rectangular frame housing 10, as well as the arrangement of the inner spring 14, the outer spring 15 and the buffer rod 13 on the auxiliary sliding block 12, provide a good buffering effect for the clamping process.

[0049] When clamping ductile iron castings, it can effectively absorb the impact force and avoid damage to the ductile iron castings due to excessive clamping force. At the same time, it can also reduce the vibration of the equipment during operation and improve the stability and service life of the equipment.

[0050] Convenient and flexible operation: the user only needs to control the extension and retraction of the electric secondary telescopic rod 20 to realize the movement control of the clamping arm 19, and the operation is simple and convenient.

[0051] The clamping force and clamping position can be flexibly adjusted according to different ductile iron casting sizes and drilling requirements, which improves the applicability of the equipment.

[0052] Reasonable structural design: The quadrilateral design of the core support plate 1 and the support legs 2 at the four corners on the lower side provide stable support for the entire device.

[0053] The various components work closely together and are reasonably laid out, allowing the equipment to operate efficiently and stably during operation.

[0054] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
