【摘要】 制动主缸补偿孔测量仪主要用于测量汽车液压制动主缸缸体补偿孔的位置、尺寸和形状，同时对主缸缸体主孔内表面的加工质量和铸造质量进行图像检测。该仪器采用高分辨率CCD成像技术，利用高精度的传动机构完成上述测量任务。该仪器具有操作简单、精度高、自动化程度高、可靠性高等特点，消除了主观因素的影响，是一种集光、机、电、算于一体的高性能精密测量仪器。 本课题研制的制动主缸补偿孔测量仪主要由计算机数据采集处理系统、控制系统、CCD成像系统、光栅位移传感器和精密机械传动系统组成。系统采用人机交互式测量，在螺旋杆下降的状态下将被试件安装在定位夹具上，螺旋杆上升并压紧在被试件上以使被试件的定位面与定位夹具靠紧，步进电机驱动滚珠丝杠旋转，从而带动内窥镜移动，同时蜗轮蜗杆带动刚性导光臂旋转，根据CCD所成图像的处理结果用鼠标确定采样点位置，并记录光栅尺的位置信息，同时将主缸内孔表面质量信息也保存起来作为数据库的一部分内容。更多还原

【Abstract】 Measuring instrument for compensating brake master cylinder is mainly to measure the place, dimension and figure of the compensated hole and at the same time to measure the quality of machining and foundry by image for inner exterior of brake master cylinder. The measuring instrument adopt high differentiate rate image technique of CCD and using high precision’s drive framework to finish the measure assignment. It has some virtues, such as easy to handle, precision is high, degree of automatization is high, dependability is high, and eliminate the influence of subjective complication. It is high-powered exactitude measuring instrument which gathered optics, mechanics, electronics and computer language.The measuring instrument for compensating brake master cylinder is made up of computer data acquire and process system, control system, CCD system, optical grating bit shift sensor and micro-machine drive system. The whole system adopt human-computer interactive measurement, when the cylinder was retracting,we can install the workpiece to be measure to orientation Fixture, and then the cylinder hold out and compaction the workpiece to be measure. To the effect that the orientation surface of workpiece to be measure can close to orientation Fixture, then the step motor drive ball leading screw circumgyrate, then drive the endoscopy to move, meanwhile worm gear drive the bar circumgyrate, bases on the result of image CCD, then confirm the place of sampling point, note the information of grating ruler, save the quality information of cylinder inner exterior, by way of the member content of the date-base.更多还原
