Camshaft gear and signal disc press-fit tooling guide slide base structure

Abstract

The invention discloses a guiding and sliding base structure of a camshaft gear and a signal disc press-fitting tool, which comprises a base, a jacking seat, a jacking bolt, a first guiding slider and a second guiding slider. The base has a rectangular parallelepiped structure; the top tightening seat is arranged on the front part of the upper plane of the base, and the top tightening seat includes a top tightening screw hole, and the top view projection of the center line of the top tightening screw hole coincides with the longitudinal center line of the base; the top tightening bolt is arranged on the top In the tightening screw hole; the first guide slider is arranged at one side of the rear part of the upper plane of the base, and the front view cross section of the first guide slider is in an inverted L shape; and the second guide slider is arranged behind the upper plane of the base At the other side of the part, the front cross-section of the first guide slider is in an inverted L shape; wherein the first guide slider and the second guide slider are arranged opposite to form a guide slide groove, and the longitudinal centerline of the guide slide groove is in line with the The longitudinal centerlines of the bases coincide. The guide slide base structure of the present invention changes the press-fit form arranged vertically into the press-fit form arranged horizontally.

Description

technical field [0001] The invention relates to the field of engine manufacturing, in particular to a press-fitting tool capable of ensuring accurate phase positioning of a camshaft gear and a signal disc. Background technique [0002] At present, the camshaft gear and the signal plate are press-fitted (shrink-fitted) at the end of the camshaft. Generally, the camshaft is placed vertically, and the positioning pins fixed on the tooling frame are used to position the camshaft gear and the signal plate (phase positioning) , Use a press to press or manually enter the way for heat sleeve. [0003] Although the structure of the press-fitting tooling in the prior art is simple, the diameter of the positioning pin will often be changed when designing the tooling because the diameter of the positioning pin fixed on the tooling frame needs to cover all camshaft gears and signal disc products with pin hole positions. The result of this is that the consistency of the pin hole phase po...

[0003] Although the structure of the press-fitting tooling in the prior art is simple, the diameter of the positioning pin will often be changed when designing the tooling because the diameter of the positioning pin fixed on the tooling frame needs to cover all camshaft gears and signal disc products with pin hole positions. The result is that the consistency of the pin hole phase positioning in the process of pressing (inserting) the camshaft gear and signal plate products is poor, and the phase deviation is large.
