Embodiment Construction

[0031] Specific embodiments of the present invention will be described in detail below in conjunction with technical solutions and accompanying drawings.

[0032]Figure 1 shows a drilling / grinding integrated combination tool, and the base of the tool is made of metal material. Countersinking countersunk hole section 1 and reaming hole section 2 are connected by taper fit, reaming hole section 2 and guide head 3 are connected by cylinder fit, and the abrasive grains on the tool surface are electroplated (brazing process, bonded abrasive can also be used sintering process, bonding process, etc.), the abrasive grains of the cone part of the expanded grinding hole section 2 are coarse-grained abrasive grains, and the cylindrical part is fine-grained abrasive grains, so as to achieve the purpose of integrating rough and fine machining. The abrasive grains on the surface of the drill bit 2 The shape of electroplating is full abrasive grain, spiral, diamond, straight line, circular, ...

Abstract

The present invention relates to an integral combined cutting-tool with hole-drilling and hole-grinding functions. Said cutting-tool is formed from three portions of counter-boring hole-grinding and hole-sinking section, hole-expanding and hole-grinding section and guide head. Said invention also provides the concrete structure of the above-mentioned every portion and its production method.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and manufacturing, and relates to a drilling / grinding integrated combined tool, especially for through-holes on the surface of various high-modulus composite materials (carbon / quartz, carbon / carbon, carbon fiber reinforced, glass steel, etc.) Or "through hole + counterbore" processing, and a high-efficiency combined hole-making tool designed for the integrated processing of through-holes or "through-hole + counterbore" on the surface of assemblies laminated with metals such as titanium alloys and aluminum alloys. Background technique [0002] Carbon fiber composites have a series of advantages and are widely used in aviation and aerospace fields. Hole processing occupies a large proportion in the machining of carbon fiber composite materials. Due to the characteristics of the material itself, its processing is difficult, the efficiency is low, and the scrap rate is high. At present...
