Description

Rotary oscillation workbench and five axle high-efficiency vertical machining centers thereof

Technical field

This utility model relates to Computerized Numerical Control processing technology field, particularly relates to a kind of rotary oscillation workbench and five Axle high-efficiency vertical machining center.

Background technology

Five-shaft numerical control processing is that grown up to overcome the deficiency of three axis machining is advanced manufactures skill Art, is to solve impeller, blade, marine propeller, heavy generator amature, turbine rotor, large-scale bavin The only resource of the processing such as oil machine bent axle.In theory, the degree of freedom of process tool is up to three Translation and three rotational freedoms, the degree of freedom of corresponding workbench is the most also six, therefrom appoints and takes five Degree of freedom designs lathe and is thus referred to as five-axle number control machine tool.The combining form of five degree of freedom has many, and one As most commonly seen be that three translational motions are plus two rotational motions compositions, existing major part five-shaft numerical control Lathe is all configured with three rectilinear coordinates axles and two rotatable coordinate axis, it is possible at computer numerical control (CNC) Under the control of system, coordination exercise simultaneously is processed.

Currently, external 5-shaft linkage numerical control lathe with American-European, Japan as representative, the five-axle linkage of these countries Digit Control Machine Tool represents the top level of current 5-shaft linkage numerical control Machine Tool Development.Foreign well-known machine tool plant at present 5-shaft linkage numerical control machine tool technology development priority can be attributed to: at a high speed, in high precision, environmental protection, intelligence, compound Change.Torque motor being widely used as revolution coordinate driving means abroad so that external machine tool feed machine Structure achieve high speed, low-loss, in high precision, high efficiency target.New machine tool technology is at five-axle linkage machine Use on bed so that five-axis linkage machine tools is simpler, in performance, the most more comes The most outstanding.

Under the effort of the departments such as country's support of relevant policies and relevant enterprise, colleges and universities, scientific research institutions, I State's 5-shaft linkage numerical control machine tool technology have also been obtained fast development and rapid progress, has gradually formed more ripe Product, there is numerous in variety, technology maturation, have the feature of proprietary technology intellectual property.But due to state Interior industrial foundation is weak, such as digital control system, grating scale feedback system, guide rail, leading screw and bearing etc., does not also have There is the brand being in world lead level, add the blockade on new techniques of same kind of products at abroad, domestic five-axle linkage Digit Control Machine Tool is the most relatively low relative to external integral level, is embodied in the difference such as stability, precision bigger.

Five-shaft numerical control Processing Technology Development is to today, although has been achieved for the biggest progress, but improves processing Quality, efficiency and stability, the requirement fully meeting production is the eternal theme of Manufacturing Technology Development, Five-shaft numerical control process technology also will develop towards the direction of higher precision, higher efficiency and more high stability.

Along with fields such as China's Aero-Space, military affairs, scientific research, precision instruments, high-precision armarium and the energy Development, some active precision workpiece to processing efficiency, the precision of shaping and The indexs such as yield rate are had higher requirement.Such as frame clsss parts such as airframe skeleton, dividing plate, crossbeams, The slewing parts such as rocket engine positions profile structural member, impeller, its material removing rate reaches about 70%, Even up to more than 90% had, these curved surface class part and large slewing parts, need to utilize five-axis robot more Center is processed, and Milling Process is as one efficient material removing method, the most complex-curved Processing, generally uses NC milling mode, and therefore, the application of five-axis milling processing is quite varied.

In conventional processes, due to the kinetic factors such as cutting force, tremor, the selection to technological parameter Overly conservative, often result in technological parameter selection improper, cause system of processing unstability, to surface to be machined matter Amount creates the more serious impact of ratio, causes piece surface to produce defect, affects serviceability and the longevity of part Life.In this context, high-efficient milling processing is suggested, and causes the weight of research worker and manufacturing and processing enterprise Depending on.So-called high-efficient milling processing, is keeping that system of processing is stable, while part to be processed quality, Limits ground improves material removing rate.International production engineering association (CIRP) has held a series of high-efficient cutting International conference, the key technology related to regard to high-efficient cutting is discussed, the domestic advanced manufacturing technology held The momentous conference of aspect the most gradually starts to pay attention to highly-efficient processing, it may be said that High Efficient Machining Technology research becomes New trend for digital control processing development.

To sum up, the efficient five-axis milling machining center that this project is studied, to China's Aero-Space, military affairs, The development in the fields such as scientific research, precision instruments, high-precision armarium and the energy suffers from important meaning.
