Description

Technical Field

[0001] The utility model belongs to the technical field of crankshaft connection in a crankshaft press, and particularly relates to a crankshaft assembly structure for a press. Background Art

[0002] As one of the key components for transmitting power in a crankshaft press, the design of its assembly structure directly affects the equipment's working efficiency and ease of maintenance. The traditional crankshaft assembly structure used in presses is mainly divided into a connecting rod seat and an assembly seat. The connecting rod seat and the assembly seat are two separate and independent parts. When assembly is required, it is often necessary to use external tools such as hangers or specially designed fixtures to first fix the connecting rod seat, and then try to install the assembly seat accurately. In this process, in order to ensure that the connecting holes are correctly aligned, the operator has to repeatedly adjust the position of the assembly seat or the connecting rod seat, which not only increases the difficulty of assembly, but also greatly prolongs the entire assembly time. In addition, frequent manual adjustments may also lead to inaccurate positioning problems, which in turn affects the final assembly quality and the safety and reliability of equipment operation.

[0003] Therefore, in view of the problems existing in the above-mentioned prior art, it is necessary to propose an improved press crankshaft assembly structure design scheme, which aims to simplify the assembly process, reduce manual intervention and improve assembly accuracy and efficiency. Utility Model Content

[0004] In order to solve the above technical problems, the present invention solves them through the following technical solutions.

[0005] A crankshaft assembly structure for a press includes a connecting rod seat and an assembly seat. The connecting rod seat and the assembly seat are assembled to form an axial hole. A wear-resistant sleeve is assembled in the axial hole. A bushing seat is assembled in the wear-resistant sleeve. The bushing seat is assembled on the crankshaft. One side of the connecting rod seat is hinged to the assembly seat, and the other side of the connecting rod seat is assembled and connected to the assembly seat via fasteners.

[0006] In a preferred technical solution for a crankshaft assembly structure for a press, the crankshaft is integrally formed. This integrally formed crankshaft design improves the overall strength and stability of the structure, reduces stress concentration points that may arise from connecting multiple components, and thus extends service life. The wear-resistant sleeve comprises two sets of wear-resistant shoes, and the bushing seat comprises two sets of bushing shoes. The wear-resistant sleeve and bushing are designed separately to match the crankshaft.

[0007] In a preferred technical solution for a crankshaft assembly structure for a press, one of the two sets of wear-resistant shoes is equipped with an axial stop groove, while the other set of wear-resistant shoes is equipped with an axial stop block that cooperates with the axial stop groove. This design prevents relative sliding between the two sets of wear-resistant shoes, ensuring their positional stability and operational stability. It also provides a certain degree of guidance, making assembly more precise and efficient.

[0008] In a preferred technical solution for a crankshaft assembly structure for a press, axial stoppers are provided at both ends of the bushing seat. One set of bushing shoes is equipped with a radial stopper groove, while the other set of bushing shoes is equipped with a radial stopper block that cooperates with the radial stopper groove. This helps prevent the bushing seat from moving axially or radially, ensuring it remains in the correct position. The design of the radial stopper groove and block further strengthens the bond between the components, improving the safety and reliability of the overall structure. The two sets of bushing shoes are assembled and connected by fasteners.

[0009] In a preferred technical solution for a crankshaft assembly structure for a press, the assembly base is provided with an oil reservoir, the opening of which is fitted with a lid. An oil outlet channel is provided at the bottom of the reservoir, leading to the inner wall of the assembly base. This design helps maintain good lubrication of moving parts, reduces the need for manual lubrication, and improves work efficiency.

[0010] Compared with the prior art, the present invention has the following beneficial effects: convenient and simple assembly and high disassembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Reference Figures 1 to 3 A crankshaft 50 assembly structure for a press includes a connecting rod seat 10 and an assembly seat 20. After the connecting rod seat 10 and the assembly seat 20 are assembled, an axial hole is formed. A wear-resistant sleeve is assembled in the axial hole. A bushing seat is assembled in the wear-resistant sleeve. The bushing seat is assembled on the crankshaft 50. One side of the connecting rod seat 10 is hinged to the assembly seat 20, and the other side of the connecting rod seat 10 is assembled and connected to the assembly seat 20 through fasteners.

[0024] The crankshaft 50 is integrally formed. This design improves the overall strength and stability of the structure, reduces stress concentration points that may arise from connecting multiple components, and thus extends its service life. The wear-resistant sleeve comprises two sets of wear-resistant shoes 30, and the bushing seat comprises two sets of bushing shoes 40. The wear-resistant sleeve and bushing are designed separately to match the crankshaft 50.

[0025] Furthermore, one group of the two groups of wear-resistant tiles 30 is provided with an axial limit groove 31, and the other group of wear-resistant tiles 30 is provided with an axial limit block 32 that cooperates with the axial limit groove 31. Such a design ensures that there is no relative sliding between the two groups of wear-resistant tiles 30, ensures their positional fixity and working stability, and can also play a certain guiding role, making the assembly more accurate and efficient. Axial limit parts 41 are provided at both ends of the bushing seat. One group of the two groups of bushing tiles 40 is provided with a radial limit groove 42, and the other group of bushing tiles 40 is provided with a radial limit block 43 that cooperates with the radial limit groove 42, which helps to prevent the bushing seat from moving axially or radially, ensuring that it is always in the correct position. The design of the radial limit groove 42 and the block further enhances the bonding between the components and improves the safety and reliability of the overall structure. The two groups of bushing tiles 40 are assembled and connected by fasteners.

[0026] For the wear-resistant sleeve and bushing seat, alloy steel with high strength, low friction coefficient and good heat resistance is preferred as the manufacturing material, and strengthening measures such as carburizing and quenching are adopted in surface treatment to significantly enhance its surface hardness and wear resistance.

[0027] In addition, the assembly base 20 is provided with an oil reservoir 21, the opening of which is fitted with a lid 22. The bottom of the oil reservoir 21 is provided with an oil outlet channel 23 leading to the inner wall of the assembly base 20. This design helps maintain good lubrication of moving parts, reduces the need for manual lubrication, and improves work efficiency.
