Displacement positioning system based on high-energy-beam scanning devices, and positioning method

Abstract

The invention discloses a displacement positioning system based on high-energy-beam scanning devices, and a positioning method. The displacement positioning system comprises a plurality of high-energy-beam scanning modules arranged on a forming chamber, and the multiple high-energy-beam scanning modules are the same in structure and each comprise a left linear guide rail and a right linear guide rail which are parallelly arranged on the forming chamber, wherein a displacement sensor is arranged in the middle of the two end points of one ends of the left linear guide rail and the right linear guide rail, rolling steel balls are arranged in the left linear guide rail and the right linear guide rail correspondingly, a connecting rod is connected between the two rolling steel balls, the two rolling steel balls are connected with a motor through lead screws, the corresponding high-energy-beam scanning device is arranged on the connecting rod, and a front field lens and a rear field lens arefurther arranged on the positions, under the corresponding high-energy-beam scanning device, at the top of the forming chamber; and the high-energy-beam scanning devices, the displacement sensors andthe motors are further connected with a computer control system. The problems that in the prior art, the size of the formed breadth of a printed part is too small in the additive manufacturing process, meanwhile the production period is long, the processing cost is high, and the equipment manufacturing and maintenance costs are high are solved.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and specifically relates to a displacement positioning system based on a high-energy beam scanning device. The invention also relates to a positioning method of the displacement positioning system based on a high-energy beam scanning device. Background technique [0002] With the continuous development of laser selective melting (SLM) forming technology, the demand for forming large and complex structural parts using this process is becoming more and more urgent. The existing SLM technology is still limited to the size of the printed parts within 600-800mm status quo. [0003] For forming large-format parts, the existing methods are: [0004] 1. It is realized by adding a fixed high-energy beam scanning device to the SLM equipment, but as the size of the printed part increases, the cost of production, equipment manufacturing and maintenance will increase accordingly; [0005] 2. ...
