A displacement positioning system and positioning method based on a high-energy beam scanning device

Abstract

The invention discloses a displacement positioning system and a positioning method based on a high-energy beam scanning device, which includes several high-energy beam scanning modules arranged on a forming room. Left and right linear guide rails, a displacement sensor is installed in the middle between the two ends of one end of the left and right linear guide rails, rolling steel balls are installed in the left and right linear guide rails, and a connecting rod is connected between the two rolling steel balls, and the two rolling steel balls pass through The lead screw is connected with the motor, the connecting rod is provided with a high-energy beam scanning device, the top of the forming chamber and directly below the high-energy beam scanning device are also provided with a front field mirror and a rear field mirror, and the high-energy beam scanning device, displacement sensor, and motor are also connected with The computer control system is connected, and the invention solves the problems in the prior art that the size of the printed part is too small in the forming process of the additive manufacturing process, and at the same time, the production cycle is long, the processing cost is high, and the equipment manufacturing and maintenance costs are high.

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. ...
