Automatic calibration, centering and bush press-fitting device for automobile torsion beam

Abstract

The invention relates to a bush press-fitting device, in particular to an automatic calibration, centering and bush press-fitting device for an automobile torsion beam, which comprises a base device and two sets of press-fitting devices symmetrically mounted on the base device respectively; a positioning device for positioning a torsion beam is mounted on the base device; the press-fitting device comprises an upper sliding press-fitting mechanism and a lower sliding mechanism; and the upper sliding press-fitting mechanism comprises an upper sliding plate, a bushing mounting pipe fixing device, and a bushing press-fitting device, the upper sliding plate and the lower sliding mechanism are connected together through a spring suspension supporting device. The upper sliding press-fitting mechanism can be allowed to slightly shake in a suspension space through the spring suspension supporting device; the position of the press-fitting device is automatically and finely adjusted; the axis of a bushing mounting pipe is found; the press-fitting axis can move in all degrees of freedom; and the axis is aligned according to the difference of workpieces. The bush press-fitting device can guarantee smooth press-fitting of the bush in place, can realize simultaneous press-fitting of the bush at two ends, has the characteristics of high working efficiency, reliable press-fitting quality and accurate positioning, and is easy to popularize and use.

Description

technical field [0001] The invention relates to a bushing press-fitting device, in particular to an automobile torsion beam automatic calibration centering press-fitting bushing device. Background technique [0002] At present, in the production process of passenger cars, the chassis system will involve bushing press-fitting, such as the connection between the front / rear sub-frame and the pillar using a swing arm, and the swing arm needs to press-fit the bushing to realize the flexible connection of the components; non-independent The connection between the torsion beam used in the suspension system and the frame also requires a flexible connection of the bushing to avoid abnormal noise caused by the mutual movement of the chassis parts directly impacting the frame when the vehicle passes through a pit. The torsion beam is directly connected to the rear wheel hub and the frame at the same time, the span is relatively long, and there is elastic torsion in itself, causing the ...
