Embodiment Construction

[0037] Embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art would recognize that the described embodiments can be modified in various ways or combinations thereof without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. Also, in this specification, the drawings are not drawn to scale, and like reference numerals denote like parts.

[0038] The multi-value measuring tool for measuring the attitude angle of the spindle head of a machine tool is used for measuring the attitude angle of the spindle head of a machine tool, especially the attitude angle of the spindle head in a five-axis linkage hybrid machine tool. In the calibration work of a five-axis linkage hybrid machine tool, it is necessary to measure the maximum inclination angle allowed in the workspace. The inclination a...

Abstract

The invention discloses a multi-valued measuring tool and a measuring method for the attitude angle of the spindle head of a machine tool. The measuring tool includes: a base, a calibration boss and at least two measuring inclined surfaces. The base is at a set angle, the calibration boss is connected to the base, the calibration boss is used to calibrate the installation direction of the base on the workbench, and the measuring gauge is installed on the base through the base. On the workbench of the machine tool, and the calibration boss is parallel to the set feed axis, the attitude angle of the machine tool spindle head in different inclination directions is measured by making the machine tool spindle perpendicular to different measuring slopes. The invention has a simple structure, has multiple measuring slopes, can measure multiple sets of data with one installation, further reduces the error introduced by human operation, and improves the measurement efficiency.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a measuring tool and a measuring method for measuring the attitude angle of a spindle head of a machine tool. Background technique [0002] Compared with traditional lathes, milling machines, drilling machines, etc., the five-axis linkage machine tool greatly improves the processing efficiency because it saves multiple clamping when processing complex parts. The five-axis linkage hybrid machine tool, because the spindle head is installed on the parallel mechanism, has the advantages of fast movement speed and good dynamic performance. During the machining process, it cooperates with the serial feed axis movement, and the machining efficiency is very high. At the same time, the structure of the parallel mechanism is complex, and the errors caused by manufacturing and assembly are difficult to measure directly. It is necessary to measure the different positions and attitudes of...
