摘　　要：型砂质量是影响铸件质量的重要因素之一,型砂性能参数便携式检测装置尤其是多参数便携检测装置对于铸型质量控制具有重要作用。本文研制了一种基于单片机测试与控制的,可实现湿型粘土砂紧实率、含水量、透气性和湿压强度生产现场同步检测的便携检测装置。文中介绍了仪器工作原理、硬件组成、软件设计和实测结果。便携式检测装置与标准检测方法检测结果对比的相对误差为紧实率0.60%、含水量2.12%、透气性1.87%、湿压强度1.61%,检测时间小于2 min,证明便携式检测装置具有较高的测试精度和工作稳定性。Molding sand quality is one of the important factors affecting the quality of castings.Portable detection device for molding sand properties,especially multi-parameter portable detection device,plays an important role in mold quality control.In this paper,a portable detection device based on single chip microcomputer testing and controlling was developed,which can finish the detection of compaction rate,water content,air permeability and wet compressive strength of wet clay sand synchronously in site.The testing principle,hardware composition,software design and measured results of the detection device were introduced in this paper.The relative error between the portable detection device and the standard method was that the compaction rate was 0.60%,the water content was 2.12%,the air permeability was 1.87%,the wet compression strength was 1.61%,and the detection time was less than 2 min,which proves that the portable detection device has high test accuracy and working stability.
