Problems solved by technology

[0006] 1. Generally, it can only move up and down and print layer by layer. For some rotating parts, it is difficult to meet the requirements of axisymmetric during processing, resulting in unqualified processed products;
[0007] 2. It is only suitable for platform-type printing abutments, and cannot meet the printing requirements of some cylindrical printing abutments

Abstract

The invention discloses a drive device for a freedom-degree printing base station for SLM equipment. The drive device comprises a rotating drive mechanism and a lifting drive mechanism. The rotating drive mechanism comprises a bottom plate. Supporting legs are fixed to four corners of the top of the bottom plate correspondingly. A supporting plate is arranged above the bottom plate. The tops of the supporting legs are fixedly connected with the bottom of the supporting plate. A rotating rod is connected to the top of the bottom plate in a rotating manner through a bearing. The top end of the rotating rod penetrates through the top of the supporting plate, and a first disc is fixed to the top end of the rotating rod. The lifting drive mechanism comprises an L-shaped fixing plate, a hydraulic rod and a hydraulic cylinder which are sequentially arranged from top to bottom. The drive device is simple in structure and convenient to use. The rotating drive mechanism and the lifting drive mechanism are adopted and combined ingeniously, vertical moving and rotating can be achieved, the requirements of some rotating parts for machining symmetry and the like are well met, quality of machinedproducts is ensured, and the drive device is applicable to the printing requirement of the cylinder-shaped printing base station.

Description

technical field [0001] The invention relates to the technical field of SLM equipment, in particular to a driving device for an SLM equipment printing platform with degrees of freedom. 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. ...
