A non-contact real-time eccentricity detection method for a helical milling device

Abstract

The invention discloses a non-contact real-time eccentric amount detection method for a spiral hole-milling device. The non-contact real-time eccentric amount detection method for the spiral hole-milling device comprises the following steps: installing a laser detection device to form a detection area; enabling a tool to penetrate through the detection area; while the tool revolves by one cycle, detecting the shortest distances from the tool to the upper edge and the left edge of the detection area every moment, denoting the shortest distances as an upper edge distance and a left edge distanceseparately, evaluating the average value of the upper edge distance and the average value of the left edge distance to adjust the eccentric amount of the spiral hole-milling device, detecting the shortest distances from the tool to the upper edge and the left edge of the detection area at a certain moment, denoting the shortest distances as a real-time upper edge distance Xn and a real-time leftedge distance Yn separately, calculating the actual eccentric amount e at this moment, and outputting and displaying; and adjusting the eccentric amount of the spiral hole-milling device in real timeaccording to the displayed actual eccentric amount e until the needed eccentric amount is obtained. According to the non-contact real-time eccentric amount detection method for the spiral hole-millingdevice, the accuracy and operability of eccentric amount adjustment are improved, the eccentric adjustment speed is increased, and the production efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of helical milling hole processing, in particular to a non-contact 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 applied...
