最近我们研究成功一台测量泵体相互位置精度的半自动检验机。采用气动测量原理,所有执行机构均是气缸,并采用气动近接传感器、气动逻辑元件等组成的控制回路。下面进行简单的介绍。 一、概况 1.被测工件及测量参数 被测工件为A型喷油泵泵体(如图1所示),被测参数为。 4—φ24孔? Recently, we studied the success of a semi-automatic testing machine measuring the mutual accuracy of the pump body. Pneumatic measuring principle, all implementing agencies are the cylinder, and the use of pneumatic proximity sensors, pneumatic logic components and other components of the control loop. Here’s a brief introduction. First, an overview 1. The measured workpiece and the measured parameters The workpiece is A-type pump body (Figure 1), the measured parameters. 4-φ24 hole?
