Seven-axis linkage numerical control abrasive belt grinding and polishing machine tool

Abstract

The invention discloses a seven-axis linkage numerical control abrasive belt grinding and polishing machine tool. The seven-axis linkage numerical control abrasive belt grinding and polishing machine tool mainly solves the problems that according to a vertical six-axis linkage abrasive belt grinding and polishing method in the prior art, asymmetrical margins on a curved face can not be stably removed and excessive cutting or insufficient cutting is easy to occur. The seven-axis linkage numerical control abrasive belt grinding and polishing machine tool comprises a rotation clamp, a top tip, a horizontal machine tool body, a pillar, a Y-direction motion device, a Z-direction motion device, an X-direction motion device, a B-direction rotation drive device and a grinding and polishing device, wherein the rotation clamp and the top tip are used for fixing a blade part. The Y-direction motion device drives the pillar to move linearly in the Y direction, the Z-direction motion device drives the pillar to move linearly in the Z direction and the X-direction motion device is used for fixing the top tip and driving the top tip to move linearly in the X direction. The B-direction rotation drive device is used for fixing the rotation clamp and driving the rotation clamp to achieve 360-degree rotation motion. The grinding and polishing device is installed on the horizontal machine tool body and on the position corresponding to the pillar. By means of the technical scheme, the objects of convenient construction, the high performance cost ratio and high precision are achieved and high utility value and popularization value are achieved.

Description

technical field [0001] The invention relates to a grinding and polishing machine tool, in particular to a seven-axis linkage numerically controlled abrasive belt grinding and polishing machine tool suitable for machining curved surfaces of blades of aeroengines, gas turbines, steam turbines and the like. Background technique [0002] As the key core parts of power energy devices such as aero-engines, gas turbines, and steam turbines, blades play a decisive role in the performance of the entire machine. The manufacturing accuracy and surface roughness of the blades have a significant impact on the performance and efficiency of the entire energy conversion device. crucial impact. Nowadays, the profiles of most blades are complex spatial surfaces, and their geometric data are free-form surfaces obtained through complex calculations, analyzes and test corrections based on the principles of fluid mechanics. These curved surfaces are not only difficult to process, but also have lo...
