Description

Technical Field

[0001] The utility model relates to the field of oil cylinders, in particular to a novel oil cylinder head. Background Art

[0002] Silicon steel sheets are important components in the motor core. Silicon steel sheets are usually formed in a mold. During the forming process, the silicon steel sheets need to be dragged by the cylinder head of the oil cylinder, and the cylinder head needs to rotate with the product. In order to improve the performance of silicon steel sheets, it is necessary to ensure the verticality of the oil cylinder head, the flatness of the contact surface between the cylinder head and the silicon steel sheet, and the smoothness of the cylinder head rotation.

[0003] However, the verticality of the cylinder head of the existing oil cylinder and the smoothness of the cylinder head rotation need to be improved. Summary of the invention

[0004] The utility model aims to provide a cylinder head with high verticality and rotational smoothness.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a new type of cylinder head, including a base, a pad is provided above the base, a top is provided above the pad, the base, the pad and the top are fixed together by a first bolt assembly; the pad and the top are fixed together by a plurality of second bolt assemblies; an axial hole is provided at the center position of the base, the first bolt assembly includes a center bolt, the center bolt is inserted from the axial hole, and the center bolt is screwed to the center position of the top after passing through the center position of the pad; a plurality of the second bolt assemblies are arranged around the first bolt assembly; a bearing is also provided between the base and the pad.

[0006] Compared with the prior art, the utility model has the advantages of: using the center bolt to directly penetrate the base, the pad to the center of the top head to ensure the vertical accuracy of the cylinder head after installation. This center alignment method fundamentally eliminates the deflection problem that may exist in traditional installation, and lays a solid foundation for the precise positioning of the silicon steel sheet during the forming process. The bearing reduces the rotation resistance, making the cylinder head movement smoother and free of jams. The bearing is a thrust ball bearing, which not only improves the smoothness of rotation, but also can withstand axial loads, extending the service life and maintenance cycle of the equipment. Dynamic balance and adaptive adjustment: The multi-point second bolt assembly arranged around the center bolt provides fine flatness adjustment capabilities for the contact surface between the top head and the silicon steel sheet. Structural reinforcement and stability improvement: Through the dual fixing strategy of the first and second bolt assemblies, not only the structural strength of the entire cylinder head assembly is strengthened, but also its vibration resistance and resistance to external interference are significantly improved. This reinforced design ensures that the cylinder head can still maintain extremely high stability and precision during high-speed rotation or long-term operation, avoiding performance degradation caused by vibration.

[0007] In some embodiments of the utility model, the center bolt is covered with a first sleeve of equal height, the lower end of the first sleeve of equal height is arranged in the shaft hole, the upper end of the first sleeve of equal height is inserted in the center position of the head, and the pad is covered on the first sleeve of equal height. This design not only strengthens the connection stability between components, but also simplifies the installation process, ensures the uniformity of the height of the cylinder head after assembly, and provides additional guarantee for the precise control of verticality.

[0008] In some embodiments of the utility model, a gap is reserved between the plug and the pad. The preset gap design between the plug and the pad leaves room for thermal expansion and contraction, ensuring that the positions of the components can be freely fine-tuned at different working temperatures, avoiding uneven force on the fasteners caused by temperature changes, and maintaining the flatness of the contact surface, thereby maintaining high smoothness of rotation for a long time.

[0009] In some embodiments of the utility model, the second bolt assembly includes an inner bolt, the inner bolt is covered with a second equi-height sleeve, the upper end of the second equi-height sleeve is connected to the top head, and the lower end of the second equi-height sleeve is connected to the backing plate. This design ensures the parallelism and consistency of the bolt connection through the equi-height sleeve, and can maintain a good centering state between the components even under complex working conditions, which contributes to improving the smoothness of cylinder head rotation and working stability.

[0010] In some embodiments of the utility model, a plurality of cylindrical springs are further provided between the pad and the top head, and the plurality of cylindrical springs are arranged around the central bolt, the upper end of the cylindrical spring abuts against the top head, and the lower end of the cylindrical spring abuts against the pad. These springs are arranged around the central bolt, with the upper and lower ends abutting against the top head and the pad, respectively, and can absorb vibration and compensate for wear during operation, while maintaining pressure balance on the contact surface, ensuring smooth operation of the cylinder head during rotation, extending the life of the equipment and reducing noise.

[0011] In some embodiments of the utility model, the base includes a flange, the bearing is arranged between the outer disk of the flange and the pad, and the bearing is sleeved with the inner disk of the flange. The flange is integrated into the base design and the bearing is arranged here, which not only enhances the load-bearing capacity and stability of the base, but also further optimizes the support structure of the bearing through the sleeve design of the bearing and the inner disk of the flange, reduces the axial and radial load stress, improves the stability and durability of the entire rotation system, and provides strong hardware support for achieving a higher level of verticality and rotation smoothness.

This center alignment method fundamentally eliminates the deflection problem that may exist in traditional installation, and lays a solid foundation for the precise positioning of the silicon steel sheet during the forming process. The bearing 7 reduces the rotation resistance, making the cylinder head movement smoother and without jamming. The bearing 7 is a thrust ball bearing 7, which not only improves the smoothness of rotation, but also can withstand axial loads, extending the service life and maintenance cycle of the equipment. Dynamic balance and adaptive adjustment: The multi-point second bolt assembly arranged around the center bolt 4 provides fine flatness adjustment capabilities for the contact surface between the top head 3 and the silicon steel sheet. Structural reinforcement and stability improvement: The dual fixing strategy of the first and second bolt assemblies not only strengthens the structural strength of the entire cylinder head assembly, but also significantly improves its vibration resistance and resistance to external interference. This reinforced design ensures that the cylinder head can still maintain extremely high stability and precision during high-speed rotation or long-term operation, avoiding performance degradation caused by vibration.

[0025] Specifically, the second bolt assembly includes an inner bolt 5, which is covered with a second contour sleeve 9, the upper end of which is connected to the top head 3, and the lower end of which is connected to the backing plate 2. This design ensures the parallelism and consistency of the bolt connection through the contour sleeve, and can maintain a good centering state between the components even under complex working conditions, contributing to improving the smoothness of cylinder head rotation and working stability.

[0026] Specifically, a plurality of cylindrical springs 10 are provided between the pad 2 and the top head 3, and the plurality of cylindrical springs 10 are arranged around the central bolt 4, with the upper end of the cylindrical spring 10 abutting against the top head 3, and the lower end of the cylindrical spring 10 abutting against the pad 2. These springs are arranged around the central bolt 4, with the upper and lower ends abutting against the top head 3 and the pad 2 respectively, which can absorb vibration and compensate for wear during operation, while maintaining pressure balance on the contact surface, ensuring smooth operation of the cylinder head during rotation, extending the life of the equipment and reducing noise.

[0027] Specifically, the base 1 includes a flange portion, the bearing 7 is arranged between the outer disk 101 of the flange portion and the backing plate 2, and the bearing is sleeved with the inner disk 102 of the flange portion. The flange portion is integrated in the design of the base 1 and the bearing 7 is arranged here, which not only enhances the load-bearing capacity and stability of the base 1, but also further optimizes the support structure of the bearing 7 through the sleeve design of the bearing and the inner disk 102 of the flange portion, reduces the axial and radial load stress, improves the stability and durability of the entire rotation system, and provides strong hardware support for achieving a higher level of verticality and rotation smoothness.
