Near-net forming method and device for multi-axis and axis variable zero component

Abstract

The invention discloses a near-net forming device for a multi-axis and axis variable zero component. The near-net forming device comprises a fixed base, a first stand column, a gantry crane, a composite moving platform, a workbench, a rotating cross beam, a linkage cross beam, a laser material reducing module and the like. The rotating cross beam horizontally moves relative to the gantry crane cross beam; the linkage cross beam rotates relative to the rotating cross beam; the material adding module and the material grinding and cutting module synchronously and horizontally move relative to the linkage cross beam; the gantry crane beam moves up and down relative to the gantry crane stand columns. The composite moving platform can horizontally move relative to the fixed base, first stand columns are arranged on the outer sides of at least two end portions of the workbench, the first stand columns are fixed to the composite moving platform, and the workbench can obliquely move relative to the first stand columns. The invention has the advantages of compact structure and the like.

Description

technical field [0001] The invention relates to the field of desktop laser material addition / subtraction processing equipment, in particular to a near-net shaping method and device for multi-axis and axis-variable components. Background technique [0002] With the near-net development of my country's economic system, the use of rotary components, which represent an important basis for the development of the machinery industry (from daily life to aviation, aerospace, navigation and national defense), is increasing year by year. From the perspective of specific processing technology and methods: ⑴The precision of material reduction processing is high, but the energy consumption, time consumption, and consumables are also high, and the yield rate is low when processing thin-walled parts; High efficiency, low energy consumption, and less loss of raw materials, but the preparation process of the blank is complicated, the design and manufacturing cost of the mold is high, and it i...

AI Technical Summary

Problems solved by technology

However, this will cause the overall size of the equipment to be too large, and a high proportion of the total energy consumption and total time consumption of processing will be lost in the reciprocating conversion of the station. Precision Machining of Inner and Outer Wall Surfaces of Complex Components with Non-Linear Radius Changes

[0004] In the compound machining process of adding / subtracting materials, the worktable can only realize translational or rotational movement, and the operation is complicated and the machining efficiency is low when machining rotating parts with special changing diameters

On the other hand, a large amount of fine waste chips are generated during cutting or grinding

If there is no targeted sealing design in the complex transmission system including multi-station composite manufacturing equipment, a large amount of waste will easily be absorbed, accumulated, and blocked in the meshing parts between the transmission parts with lubricating oil, causing serious wear and tear, resulting in transmission and processing failures. Decreased accuracy, shortened service life of key precision parts and equipment, increased repair and maintenance costs, and in severe cases, the workbench may even be seized to death
