Abstract

The invention discloses a propeller machining technology. According to the propeller machining technology, a four-axis machining center presets a movement path of a marking knife, and according to comparison of the thicknesses of the outer contours of a blank blade on the two sides of the movement path of the marking knife, whether the position of the marking knife is right or not is judged; afterthe position of the marking knife is centered, the null position of the four-axis machining center is determined, with the intersection point between the axis of a center through hole of a propellerhub and the front end face of the propeller hub at the moment as the null point, blade backs and blade faces of all the propeller blades are sequentially machined; during machining, marking on each blade of the blank is not needed, so that the machining time is greatly shortened, and production cost is lowered.

Description

Technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a propeller processing technology. Background technique [0002] Propeller refers to a device that relies on blades to rotate in air or water to convert engine rotational power into propulsion. There may be two or more blades connected to the hub. Traditional propeller processing technology requires multiple processes such as scribing the spiral line after correcting the blank, measuring the machining allowance and removing the excess allowance, and each blade of the propeller blank needs to be scribed and the machining allowance removed. Time-consuming, laborious, and high production cost. [0003] Therefore, in order to solve the above problems, a propeller machining process is needed, which can preset the scribing tool movement path through the four-axis machining center, and judge the scribing based on the comparison of the scribing tool movement path and the thicknes...
