Problems solved by technology

[0006] 1. Generally, the printing platform can only move up and down, and print layer by layer. It is difficult to meet the requirements of axisymmetric when processing some rotating parts, resulting in unqualified processed products;
[0007] 2. There is a lack of a driving device suitable for the degree of freedom printing abutment. The existing driving device is only suitable for platform-type printing abutments, and cannot meet the printing requirements of some long-strip (or long-shaped) printing abutments

Abstract

The invention discloses a degree-of-freedom printing base table of SLM equipment. The degree-of-freedom printing base table comprises a printing base table body, a rotary driving mechanism and a lifting driving mechanism. The printing base table body comprises a base table connecting part and a base table body. The rotary driving mechanism comprises a bottom plate, supporting legs are fixed to thefour corners of the top of the bottom plate, a supporting plate is arranged above the bottom plate, the tops of the supporting legs are fixedly connected to the bottom of the supporting plate, a rotating rod is rotatably connected to the top of the bottom plate through a bearing, and the top end of the rotating rod penetrates through the top of the supporting plate and is fixedly provided with afirst disc. A driving device of the printing base table is simple in structure and convenient to use, well meets the requirements for machining symmetry and the like of some rotating components (axialsymmetry), guarantees the quality of machined products, adopts ingenious combination of the rotating driving mechanism and the lifting driving mechanism, and can move up and down and rotate.

Description

technical field [0001] The invention relates to the technical field of SLM equipment, in particular to a degree-of-freedom printing base of the SLM equipment. Background technique [0002] Selective laser melting (SLM) metal 3D printing technology (Selective laser melting, SLM) uses a precise focus spot to quickly melt the pre-laid layers of metal powder, and can almost directly obtain functional parts with arbitrary shapes and complete metallurgical bonding. The density can reach nearly 100%. It is a rapid prototyping technology with great development prospects, especially in aerospace, medical, automobile, mold and other fields, which has extremely important application prospects. [0003] Chinese Invention Patent No. CN201720583224.9 provides a fast leveling device for the base of SLM equipment. The base shaft can move up and down, but its processing technology is printed layer by layer from top to bottom. All grow axially, limited by diameter. To make matters worse, th...
