Abstract

The invention relates to a wedged connecting rod bushing press fitting positioning mechanism, comprising a large-head positioning mechanism, a small-head positioning mechanism and a bushing press fitting positioning mechanism all arranged on the top of a worktable; the bushing press fitting positioning mechanism adopts a mandrel with a split structure for press fitting; a wedged bushing is mounted on the mandrel; a circumferential phase angle between the wedged inclined surface of a pressing sleeve and a positioning steel ball subjected to fine adjustment through a fastening screw; the wedge surface phase angle of the wedged bushing is adjusted through a hold-down screw; and the connecting rod bushing is press-fitted into a hole formed at the small head of the wedged connecting rod positioned by the large-head positioning mechanism and the small-head positioning mechanism. The wedged connecting rod bushing press fitting positioning mechanism is convenient for press fitting and accurate in positioning.

Description

technical field [0001] The invention relates to a positioning and pressing device for a wedge-shaped connecting rod bushing, in particular to a press-fitting and positioning mechanism for an engine connecting rod bushing whose small head is a wedge-shaped structure. Background technique [0002] In the existing connecting rod wedge-shaped bush pressing fixture, the structure of the pressure head assembly is usually used: the pressure sleeve and the bush are installed on the pressure column body, and the pressure sleeve and the pressure column body are positioned and connected with the positioning pin. And the production deviation of the phase angle of the positioning pin hole of the pressure column body. Under the action of the wedge-shaped inclined surface of the pressure sleeve, the axis of the bush after positioning is not parallel to the axis of the small head hole of the connecting rod. For the correction of the inner cylindrical surface, the pressure only acts on a...
