Description

Technical Field

[0001] This utility model relates to the field of tooling and fixtures, specifically to a high-horsepower tensioning device press-fitting tooling. Background Technology

[0002] As an important component of the chassis of engineering machinery, the tensioning device is made up of multiple parts pressed together.

[0003] like Figure 1 As shown, existing high-horsepower tensioning devices include an intermediate shaft, a tension spring, mounting blocks, a large nut, and a locking plate. The tension spring is sleeved on the intermediate shaft, and the mounting blocks are fixed on both sides of the tension spring, forming a limiting part on the mounting blocks. The large nut is threadedly connected to the intermediate shaft and abuts against one side of the mounting block, and the locking plate is installed on the nut. This type of high-horsepower tensioning device has problems such as high requirements for equipment tonnage, high requirements for the parallelism of the mounting blocks at both ends, easy rotation of the tension spring during the pressing process, and inability to adjust the mounting blocks at both ends after pressing. Therefore, it often requires customized pressing equipment, resulting in relatively high equipment and pressing costs.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problems of existing technologies requiring customized press-fitting equipment and resulting in relatively high equipment and press-fitting costs, this utility model provides a high-horsepower tensioning device press-fitting fixture. The press-fitting fixture includes: a fixed base with a slotted groove suitable for bolted connection with the press-fitting equipment; a first limiting seat suitable for mating with a limiting part; and a first fastener suitable for abutting against the limiting part on the first limiting seat; and a mounting base including a connecting plate suitable for connection with the press-fitting equipment, a mounting plate opposite to the fixed base, and a connecting rod connecting the mounting plate and the connecting plate; the connecting plate has a slotted groove; the mounting plate has a second limiting seat suitable for mating with the limiting part; and a second fastener suitable for abutting against the limiting part on the second limiting seat.

[0006] In the utility model, the fixing base and the mounting base are bolted on the common press-fitting equipment, thereby avoiding customizing the press-fitting equipment; meanwhile, the spring is prevented from rotating in the press-fitting process, the parallelism of the mounting blocks at the front and rear ends of the tensioning device and the press-fitting size are ensured, and the press-fitting efficiency and the press-fitting quality are improved.

[0007] Further, the avoiding groove for avoiding the intermediate shaft is formed on the fixing base and the mounting base. Through the above arrangement, the avoiding groove can facilitate the intermediate shaft to pass through, thereby facilitating the installation of the large nut, the locking plate and the like.

[0008] Further, the connecting plate comprises the oppositely arranged first supporting plate and second supporting plate, and the waist-shaped groove is formed on the first supporting plate and the second supporting plate. Through the above arrangement, the connecting plate is divided into the first supporting plate and the second supporting plate, thereby reducing the material of the connecting plate and reducing the cost of the press-fitting tool.

[0009] Further, the T-shaped bolt adapted to be connected with the press-fitting equipment is arranged in the waist-shaped groove. Through the above arrangement, the T-shaped bolt can conveniently mount the fixing base and the mounting base in the workbench T-shaped groove of the press-fitting equipment.

[0010] Further, the first limiting part comprises the first limiting plate and the second limiting plate oppositely arranged with the first limiting plate.

[0011] Further, the bolt hole is formed on the first limiting plate, and the first fastener is the lifting ring screw matched with the bolt hole. Through the above arrangement, the lifting ring screw can not only limit the limiting part, but also conveniently hoist and transport the tool and the like. BRIEF DESCRIPTION OF DRAWINGS
