Problems solved by technology

[0002] During the processing and manufacturing process of the cylinder head, some hole openings will produce ridges, and the hanging ridges will affect the cleanliness of the appearance of the cylinder head, which requires that the ridges of the cylinder head holes need to be Simple and suitable tool for removing the edge. If the production site does not have a simple and suitable tool for removing the edge, but use a small file to remove the edge of the hole, it will easily cause scratches on the hole wall, and the removal of the edge will not be complete, and it will take a long time , it is likely to cause hidden dangers to the quality and safety of the engine

Abstract

The invention discloses a tool for removing orifice burrs. The tool comprises a handle, a connecting rod, a drill bit, a collet chuck and a tightening cover. One end of the connecting rod is vertically fixed to the middle of the side face of the handle. The connecting rod is provided with an axial drill bit shank insertion hole, and a conical hole is formed in the outer end of the drill bit shank insertion hole. A drill bit insertion hole is formed in the axial direction of the collet chuck. The collet chuck has elasticity and can achieve shrinkage distortion so that the drill bit can be clamped. One end of the periphery of the collet chuck is provided with an insertion outer conical surface matched with the conical hole of the connecting rod. A clamping groove is formed in the upper middle portion of the periphery of the collet chuck. A locking outer conical surface is arranged at the other end of the periphery of the collet chuck. One end of the inner circumference of the tightening cover is fixedly connected with the other end of the connecting rod. The upper middle portion of the inner circumference of the tightening cover is provided with a clamping boss matched with the clamping groove of the collet chuck, and the other end of the inner circumference of the tightening cover is provided with a pressing conical surface matched with the locking outer conical surface of the clamping collet chuck. By means of the tool for removing the orifice burrs, the orifice burrs can be removed thoroughly; and moreover, the orifice wall cannot be scratched, consumed time is short, and burr removing efficiency is high.

Description

technical field [0001] The invention relates to the field of engines, in particular to a tool for removing the edge of an orifice. Background technique [0002] During the processing and manufacturing process of the cylinder head, some hole openings will produce ridges, and the hanging ridges will affect the cleanliness of the appearance of the cylinder head, which requires that the ridges of the cylinder head holes need to be Simple and suitable tool for removing the edge. If the production site does not have a simple and suitable tool for removing the edge, but use a small file to remove the edge of the hole, it will easily cause scratches on the hole wall, and the removal of the edge will not be complete, and it will take a long time , It is likely to cause hidden dangers to engine quality and safety. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be t...
