Sliding guide base structure of cam gear and signal panel press-fitting tooling

Abstract

The invention discloses a sliding guide base structure of a cam gear and signal panel press-fitting tooling. The sliding guide base structure comprises a base, a tight propping seat, a tight proppingbolt, a first sliding guide block and a second sliding guide block, wherein the base adopts a rectangular parallelepiped structure; the tight propping seat is arranged at the front part of the upper plane of the base, and comprises a puller screw hole, and the downward projection of the center line of the tight propping screw hole coincides with the longitudinal center line of the base; the tightpropping bolt is arranged in the tight propping screw hole; the first sliding guide block is arranged on one side of the rear part of the upper plane of the base, and the forward cross section of thefirst sliding guide block is in the shape of an inverted L; the second sliding guide block is arranged on the other side of the rear part of the upper plane of the base, and the forward cross sectionof the first sliding guide block is in the shape of a reverse inverted L; and the first sliding guide block and the second sliding guide block are oppositely arranged to form a sliding guide groove, and the longitudinal center line of the sliding guide groove coincides with the longitudinal center line of the base. According to the structure of the sliding guide base, a vertical press-fitting manner is changed into a horizontal press-fitting manner.

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.
