Multi-purpose hub bolt quick press installation device

Abstract

The invention discloses a multipurpose hub bolt rapid press-fitting device. The multipurpose hub bolt rapid press-fitting device comprises a press and a workbench, and further comprises a pressing rod, a pressing rod slide rail mechanism, a locating rotary disc, a supporting board and a supporting board lifting mechanism. The locating rotary disc is arranged on the workbench. The supporting board is arranged in the locating rotary disc. The locating rotary disc is provided with a bolt press-fitting hole being in fit with a bolt hole in a hub. The pressing rod comprises a pressing frame and a working end. When the bolt is pressed, the working end moves to the position above a bolt pre-plugged in the bolt hole of the hub through the pressing rod slide rail mechanism, and the working end of the pressing rod is pressed to the bolt on the hub through the press. The lever-type double-pressing-rod structure is adopted, two bolts are pressed at a time in every stroke of the press, the efficiency is doubled than that of the mode that single bolts are pressed one by one, the requirement of the product rhythm is met, action force of one bolt and action force of the other bolt interact and balance with each other when press fitting is carried out due to the lever-type structure, and therefore the bolts can be effectively pressed in place.

Description

technical field [0001] The invention relates to a mechanical assembly and processing device for automobile parts, more specifically, it relates to a multi-purpose fast press-fitting device for hub bolts applied to axle hub bolts. Background technique [0002] Hub bolts are the main fasteners for installing tires on axles. The combination with the hub is interference fit. Each axle has 2 hubs and a total of 20 hub bolts. The assembly method is generally pressed in by a press. In the production of axles, press Fitting hub bolts is a high frequency job. In the stage of small batch production of axles, the method of pressing individual bolts one by one is adopted. The press needs 20 strokes to complete the assembly of one axle hub bolt. Although this method has simple tooling and great flexibility, the production efficiency is low. , The physical exertion of the operator is large, and the energy consumption is also large, so it can only be adapted to maintenance and small batch...

AI Technical Summary

Problems solved by technology

In the stage of small batch production of axles, the method of pressing individual bolts one by one is adopted. The press needs 20 strokes to complete the assembly of one axle hub bolt. Although this method has simple tooling and great flexibility, the production efficiency is low. , the operator consumes a lot of physical strength and energy consumption, so it can only be adapted to maintenance and small batch production

With the increase of output, this operation method can no longer meet the needs of the production cycle. Later, a device for pressing 10 hub bolts at the same time was researched and developed. With this device, the press only needs 2 strokes to complete an axle. The assembly work of the hub bolts meets the requirements of the production cycle, but this device has a single function, and it can only be used for pressing the hub bolts of one center distance when arranged on the production line. The hub bolts of other center distances need to be pressed by another pressure outside the production line. The machine adopts the method of pressing single bolts one by one for pressing, and then transfers to the production line for assembly in the next process after pressing, which not only increases the investment in equipment, but also occupies more production land and increases the material flow in the production process and the number of employees used, and it also brings a lot of disadvantages to the layout of the workshop and the organization of production

[0003] With the rapid development of the enterprise, there are more and more product varieties and larger output, especially for the production of European-style axles with special structures such as MCB. Need to develop a wide adaptability, efficient and fast multi-purpose hub bolt quick press-fitting device
