Test bed for visual measurement system of test piece high temperature deformation machine

Abstract

The invention discloses a test bed for a visual measurement system of a test piece high temperature deformation machine. The test bed is characterized by being composed of a heating furnace part, a visual detecting part and a control system. The heating furnace part comprises a heating furnace, a heating furnace shell, a heating furnace inner cavity, a blower, two air ducts, two air duct covers, two quartz glass windows, two infrared heating tubes, an insulation material and a test piece table. The visual detecting part comprises two high speed cameras, two sets of video camera combination type supports, an industrial control computer and software. The control system part comprises a closed-loop control system and a visual detecting system of the visual detecting part, wherein the closed-loop control system has a control adjusting effect on the temperature in the heating furnace. The test bed is based on the machine visual measurement technology, micro-deformation of the test piece under the condition of high temperature can be measured, teaching demonstration on the machine visual measurement technology which is currently in typical application can be conducted, and the test bed can be used as an open type multifunctional test platform for correlative technique research and development.

Description

Problems solved by technology

However, at present, universities and scientific research institutes can only teach related technologies through specific examples, without experimental research instruments or means, let alone openness and universality, and it is difficult to meet the requirements of the diversity of machine vision inspection and measurement technology applications. It makes it difficult to effectively carry out teaching and scientific research for the corresponding technology
