Development of Intelligent Detector for Special Spring Stiffness

摘要: 针对机械式控温器中常用的特种拉簧，研制了一种智能弹簧刚度检测设备。通过对控温器用弹簧结构的分析，设计了刚度检测仪的机械机构和控制系统，实现了对弹簧的自动装簧、拉伸测量和分拣。智能检测仪提高了检测效率与精度，检测速度可达400个/小时，测量误差为±0.002 N/mm。

Abstract: An intelligent detector for special tension spring stiffness used in mechanical thermostat was de-veloped. Thought analyzing the structure of thermostat spring, the mechanical part of stiffness detector was designed which was used to clamp and pull the spring automatically. The detector used 8051 SCM as the controlling core, and a high-precision force sensor was used to collect force data. The stiffness value of springs was detected quickly and accurately, and the springs were classified according to test data. This detector improves the detection efficiency and accuracy ef-fectively. Detection rate can reach more than 400/hour. Measurement error is ±0.02 N/mm.
