Abstract

The invention discloses a small high-speed five-axis linkage machine tool, which comprises a foundation structure, a spindle box component and a cradle type worktable. The spindle box component is supported on the foundation structure, and a crossbeam with a frame-shaped structure is arranged on two upright columns to form a bridge-type portal structure. The torque bearing capacity of the crossbeam is improved, the small high-speed five-axis linkage machine tool has all advantages of a five-axis linkage machine tool in the prior art, and carries identical machining reacting force, the volume of a structural part is reduced, and the weight of the structural part is greatly lightened; a spindle box is positioned between two transverse rods of the frame-shaped crossbeam, overturning moment is eliminated, and the stability of the machine tool can be guaranteed; in addition, sizes of various components are greatly reduced on the premise of identical machining capacity, and the stroke of the machine tool can be large in the design; and by the aid of the structure, the machining precision is greatly improved, the machining range is greatly expanded, better dynamic characteristics and higher feeding speed and higher cutting speed can be realized, cutting and machining time is greatly shortened, better surface machining quality is obtained, and machining efficiency is enhanced.

Description

technical field

[0001] The invention relates to a machine tool, in particular to a high-speed five-axis linkage machine tool. Background technique

[0002] The five-axis linkage machine tool is a relatively advanced equipment among CNC machine tools. It can complete the processing of complex curved surfaces with high efficiency and high precision through one clamping, such as large generator rotors, ship propellers, and large diesel engine crankshafts. For example, in the machining of the turbine rotor of a molecular pump, the machining of the blades on the turbine rotor requires relatively high machining accuracy, and because the gap between the blades is small, only tools with a relatively small diameter can be used. To ensure the linear speed of cutting, it is necessary to use high-speed rotation The machining of the main shaft, and the use of high-speed small five-axis linkage machine tool to process the integral turbine rotor can solve the above problems well.
