Abstract

The invention discloses a contact type real-time offset detecting method of a spiral hole milling device. The method comprises the following steps that a first contact type detecting device and a second contact type detecting device are mounted, wherein the contact ends of the first contact type detecting device and the second contact type detecting device can move in the direction perpendicular to the axis of a tool and are always attached to the portion, with a round cross section , of the tool; the tool makes revolution for a circle, the displacement average value of the first contact end and the displacement average value of the second contact end are obtained, the offset of the spiral hole milling device is adjusted, the displacement of the contact ends of the first contact type detecting device and the second contact type detecting device at a certain moment is detected, the offset e at this moment is calculated, and the actual offset e at this moment is output and displayed; andaccording to the actual offset e, the offset of the spiral hole milling device is adjusted in real time until the needed offset is obtained. according to the contact type real-time offset detecting method, the accuracy and maneuverability of offset adjustment are improved, the offset adjusting speed is increased, the production efficiency is improved, the cost is low, and the measurement stability is high.

Description

technical field

[0001] The invention relates to the technical field of helical milling hole processing, in particular to a contact-type real-time eccentricity detection method of a helical milling device. Background technique

[0002] Helical milling is a new technology in the aviation manufacturing industry. Its principle is to use a special end mill. The tool itself revolves around the axis of the hole to be machined while rotating at high speed, and feeds in the direction of the axis of the hole to be machined. Finally, a milling hole is milled on the workpiece. The machining method of a circular hole with a diameter larger than the tool itself is called a helical milling hole because the tool feed trajectory is helical. For the hole making of new materials such as composite materials and titanium alloys, because the axial cutting force of helical milling holes is smaller than that of drilling holes, it is superior to traditional drilling. Helical milling holes are applie...
