Press mounting tool for engine cylinder cover valve guide pipe

Abstract

The invention discloses a press mounting tool for an engine cylinder cover valve guide pipe. The press mounting tool for the engine cylinder cover valve guide pipe comprises a base and at least three parallel inclined struts, and the inclined struts are arranged on the base; each inclined strut is provided with a bottom surface, a first inclined surface and a second inclined surface, the first inclined surfaces and the second inclined surfaces are mutually perpendicular, face plates are arranged on the first inclined surfaces, and baffles are mounted on the second inclined surfaces; the first inclined surfaces are provided with upper positioning blocks for positioning the face plates; positioning holes which are matched with the upper positioning blocks are formed in the face plates; bottom surfaces of the inclined struts are provided with lower positioning blocks for positioning of the inclined struts; positioning holes which are matched with the lower positioning blocks are formed in the base. According to the press mounting tool for the engine cylinder cover valve guide pipe, a cylinder cover is supported through the inclined face plates and baffles on the inclined struts; the axis of a valve guide pipe hole in the cylinder cover can be located in a vertical plane, and the guide pipe pressing tool can conveniently press the valve guide pipe into the valve guide pipe hole of the cylinder cover; the whole structure of the press mounting tool is simple; the press mounting is convenient; the efficiency is high; the position accuracy of the valve guide pipe after press mounting can be improved.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to an engine cylinder head valve guide press-fitting tooling. Background technique [0002] Compressing the valve guide is a very important process in the processing of the cylinder head of the automobile engine. The main reason is that in the process of pressing the guide tube, the pressing force and the position of the cylinder head must be controlled very well, especially the position of the cylinder head. There can be no slight deviation in the pressing process, which requires a very good clamp to clamp the cylinder head. At the same time, because the position of the valve guide hole of the cylinder head is inclined, this increases the difficulty of pressing the guide tube. In general, the tooling fixture for pressing the valve guide hole is a combination fixture, which requires workers to have very skilled skills to adjust the position to complete the installation process, making the work e...

[0002] Compressing the valve guide is a very important process in the processing of the cylinder head of the automobile engine. The main reason is that in the process of pressing the guide tube, the pressing force and the position of the cylinder head must be controlled very well, especially the position of the cylinder head. There can be no slight deviation in the pressing process, which requires a very good clamp to clamp the cylinder head. At the same time, because the position of the valve guide hole of the cylinder head is inclined, this increases the difficulty of pressing the guide tube

Under normal circumstances, the tooling fixture for pressing the valve guide hole is a combination fixture. During the installation process, workers need to have very skilled skills to adjust the position to complete it, which makes the work efficiency of this process very low.

[0003] Moreover, the currently used tooling fixtures are not only complex in structure, but also inconvenient for press-fitting operations, and the position error of the valve guide after press-fitting is large.
