Double-tilt-angle universal milling head rotating shaft locating precision measuring device

Abstract

The invention discloses a double-tilt-angle universal milling head rotating shaft locating precision measuring device, and discloses a device and detection method suitable for the rotary precision detection of an A / B, C axis moment motor driven and machinery driven numerical control double-tilt-angle universal milling head. The device comprises a 12-surface or 36-surface prism and an autocollimator, wherein the 12-surface or 36-surface prism is arranged on a locating shaft, the 12-surface or 36-surface prism is located by a shaft neck and an end face on the locating shaft, the other side is provided with a gland and a nut, and the 12-surface or 36-surface prism is fixed on the locating shaft by the gland and the nut. The device provided by the invention is compact in structure and easy and convenient to operate, can adjust the location fast and effectively, guarantees that the connection detection center of detection elements such as a 36-surface prism and a 36-surface prism is overlapped with the centre of the A / B, C axis, guarantees the veracity and effectiveness of detection results, and further guarantees the positioning precision of the double-tilt-angle universal milling head, thereby meeting the high-precision machining requirements; the fixture is low in cost and has high precision and high stability.

Description

technical field [0001] The present invention relates to a device and detection method suitable for detecting the rotation accuracy of a numerically controlled double-swing angle universal milling head driven by torque motors and mechanically driven by A / B and C axes, in particular to a positioning of the rotation axis of a double-swing angle universal milling head Precision measuring device. Background technique [0002] The original CNC double-swing angle universal milling head has no detection device and detection method for the positioning accuracy of the rotation axis. The imported double-swing angle universal milling head supplier only provides the positioning accuracy of the encoder, but cannot provide detection methods and cannot guarantee five-axis high-precision machining. need. Therefore, it is urgent to invent detection devices and methods to realize accurate detection. Contents of the invention [0003] The object of the present invention is to provide a devi...
