Abstract

The invention discloses a helical hole milling-dimpling-rounding integrated tool. The helical hole milling-dimpling-rounding integrated tool comprises a tool body composed of a tool handle and a cutting part. The cutting part comprises a helical hole milling cutting edge part, a helical hole milling cutting neck part, a rounding cutting edge part and a dimpling cutting edge part which are arranged sequentially from front to back. The dimpling cutting edge part is connected with the tool handle. The helical hole milling cutting edge part comprises three helical hole milling cutting edges arranged in the peripheral direction of the tool body. The rounding cutting edge part comprises three rounding cutting edges arranged in the peripheral direction of the tool body. The dimpling cutting edge part comprises three dimpling cutting edges arranged in the peripheral direction of the tool body. The edge parts of the three rounding cutting edges are located in the non-slotted position of the helical hole milling cutting neck part. The front ends of the rounding cutting edges are all tangential to the outer diameter of the helical hole milling cutting neck part, and the rear end of each rounding cutting edge is tangential to the front end of the correspondingly arranged dimpling cutting edge. The three rounding cutting edges and the helical hole milling cutting edge part are arranged in a staggered mode. The machining precision is improved by adopting the helical hole milling-dimpling-rounding integrated tool.

Description

technical field [0001] The invention relates to a special tool for machining spiral milling holes, spot facing and rounding of holes with a diameter of 4mm to 12mm, in particular to a tool for processing carbon fiber composite material / titanium alloy laminated components with spiral milling, spot facing and rounding. Special tool for head bolt connection holes. Background technique [0002] With the development of the aviation industry, traditional drilling can no longer meet the actual requirements. Helical milling is a new processing method with better processing quality and higher efficiency. In the process of processing, the application of carbon fiber composite material / titanium alloy laminated components is increasing. In order to ensure the processing efficiency, assembly quality and surface quality, the laminated materials should be integrated into holes, and the diameter of the laminated components is 4mm ~ 12mm. The application of special tools for milling holes i...
