【摘要】：本文設(shè)計(jì)了汽車制動(dòng)缸內(nèi)部檢測裝置。其主要功能為檢測制動(dòng)缸內(nèi)部補(bǔ)償孔的位置以及檢測其內(nèi)部是否存在砂眼、裂紋等質(zhì)量問題。由于制動(dòng)缸外部輪廓比較復(fù)雜,屬于深細(xì)盲孔,并且所需檢測的補(bǔ)償孔的檢測基準(zhǔn)為制動(dòng)缸外部法蘭的外端面,因此準(zhǔn)確的檢測補(bǔ)償孔的位置成為汽車行業(yè)的一大難點(diǎn)。本文設(shè)計(jì)的檢測裝置通過微位移傳感器采集零點(diǎn),通過搭接的線陣CCD進(jìn)行圖像掃描,通過計(jì)算機(jī)進(jìn)行圖像處理,各個(gè)部分在回轉(zhuǎn)工作臺(tái)與機(jī)械進(jìn)給裝置的協(xié)調(diào)下,實(shí)現(xiàn)對工件的檢測。檢測精度高、速度快且操作方便,符合現(xiàn)代工業(yè)的測量的標(biāo)準(zhǔn)。檢測裝置可達(dá)到的技術(shù)指標(biāo)為:精度:0.03%FS,分辨率:0.001mm,重復(fù)性:0.005mm。
[Abstract]:In this paper, the internal detection device of automobile brake cylinder is designed.Its main function is to detect the position of compensation hole in brake cylinder and whether there are quality problems such as sand hole and crack inside.Because the external profile of brake cylinder is complex, it belongs to deep and thin blind hole, and the inspection datum of compensation hole is the external end face of external flange of brake cylinder, it is difficult to accurately detect the position of compensation hole in automobile industry.The detection device designed in this paper collects zeros by micro-displacement sensor, scans images by overlapping linear CCD, and processes images by computer. Each part is coordinated with the rotary table and the mechanical feed device.The detection of the workpiece is realized.High precision, high speed and convenient operation, accord with the standard of modern industry.The technical specifications of the detection device are: precision: 0.03FS, resolution: 0.001mm, repeatability: 0.005mm.
