Clamping device and processing method for drilling oblique oil holes in engine cylinder head

Abstract

The invention discloses a clamping device for machining an inclined oil hole drilled in an engine cylinder head. The clamping device comprises a bottom plate, a positioning mechanism arranged on the bottom plate and used for positioning the engine cylinder head, pressing mechanisms for pressing the engine cylinder head, and a drilling guide mechanism for guiding a drill bit on a horizontal type machine tool. According to the clamping device for machining the inclined oil hole drilled in the engine cylinder head, through the arrangement of the positioning mechanism, the pressing mechanisms and the drilling guide mechanism, precise clamping and positioning of the engine cylinder head are achieved, the machining precision of the inclined oil hole in the engine cylinder head is improved, clamping efficiency and pressing reliability are improved, and machining efficiency of the inclined oil hole is improved. The invention further provides a machining method for the inclined oil hole drilled in the engine cylinder head.

Description

technical field [0001] The invention belongs to the technical field of clamping devices, and in particular, the invention relates to a clamping device for processing an inclined oil hole in a cylinder head of an automobile and a method for processing the inclined oil hole in the cylinder head of the engine. Background technique [0002] When the automobile engine is working, the lubricating oil in the oil channel of the cylinder head flows into the low-pressure oil chamber in the tappet body through the oil gauge hole, the inclined oil hole and the annular oil groove, so as to ensure the normal operation of the tappet. Here, the oblique oil hole is a slanted and slender hole, which makes it difficult to machine the engine cylinder head in the machining process of the oblique oil hole. The general processing method is to place the cylinder head on a radial drilling machine for adjustment by skilled workers. Position to process, because the position is difficult to find, the p...

Problems solved by technology

Here, the oblique oil hole is a slanted and slender hole, which makes it difficult to machine the engine cylinder head in the machining process of the oblique oil hole. The general processing method is to place the cylinder head on a radial drilling machine for adjustment by skilled workers. location to process, because the location is difficult to find, the processing error of this process is relatively large, and the processing efficiency is low

At the same time, many engine cylinder head manufacturers currently use low-cost vertical machine tools to process the oblique oil holes in the cylinder head. The processing technology is complicated, the tooling and fixture are heavy, and the precision is low, so that the processing quality is not high.
