Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile leaf spring production and maintenance equipment, and particularly relates to a hand-held sleeve pressing device. BACKGROUND

[0002] The ear bushing is an important element in the automobile suspension system. The sleeve pressing device used in the present production is mainly manually installed or loaded by fixed machinery (such as small-sized pressing machines).

[0003] Since the ear bushing is generally in interference fit with the ear hole of the leaf spring ear, a large loading force is required when the bushing is installed. When manually installed, the ear bushing is often hammered several times, so that the concentricity and coaxiality of the bushing and the ear hole will have a large deviation after pressing, which affects the installation and the final life of the automobile leaf spring. When using mechanical pressing, the equipment scale is usually large, the tooling die is complex to replace, and the cost is high, which indirectly leads to the rise of production cost, and the equipment is not easy to move.

[0004] Therefore, it is urgent to design a hand-held, flexible automobile leaf spring bushing pressing device that can be moved in a small range to solve the problems of time-consuming and laborious manual operation, large deviation, high mechanical operation cost, and inflexible movement in installing the ear bushing in the ear hole of the existing ear leaf spring.
