Attitude angle measuring device and measuring method for spindle head of five-axis linkage machine tool

Abstract

The invention relates to an attitude angle measuring device and a measuring method for a spindle head of a five-axis linkage machine tool. The attitude angle measuring device comprises a standard device mounted on the spindle head of the five-axis linkage machine tool and a detecting device mounted on a workbench of the five-axis linkage machine tool, wherein the standard device comprises a standard plane and a clamping part arranged perpendicular to the standard plane; the clamping part is arranged in a knife handle of the spindle head of the five-axis linkage machine tool in an inserting manner; the detecting device comprises a basal plate which is fixedly connected to the workbench of the five-axis linkage machine tool and a fixing part which is fixedly connected to the basal plate and perpendicular to the basal plate; and the fixing part is fixedly connected with a length gauge arranged perpendicular to the basal plate. According to the attitude angle measuring device for the spindle head of the five-axis linkage machine tool disclosed by the invention, own structural characteristics of the five-axis linkage machine tool are fully utilized, the manufacturing cost is reduced, and the structure and a measuring link are simplified, so that few errors are introduced, and high measuring accuracy can be achieved; and according to the measuring method for the spindle head of the five-axis linkage machine tool disclosed by the invention, the characteristic that a linear feed shaft of the five-axis linkage machine tool is in closed-loop control is utilized, so that the structure is greatly simplified, and the measuring cost is reduced.

Description

technical field [0001] The invention relates to a measuring device and a measuring method, in particular to a measuring device and a measuring method for the attitude angle of a spindle head of a five-axis linkage machine tool. Background technique [0002] Due to the flexibility of the tool posture, the five-axis machine tool can avoid multiple clamping, reduce the cost of the fixture, reduce the cutting force, and improve the tool life in the cutting process, which greatly improves the processing efficiency. At the same time, the five-axis linkage machine tool is also considered to be the only way to solve the processing of impellers, blades, large rotors, and large diesel engine shafts, and is a key technology in the mechanical equipment manufacturing industry. Due to the complex mechanical structure of the five-axis linkage machine tool, there are a large number of processing and assembly errors. Therefore, for the five-axis linkage machine tool, it is necessary to accur...
