【摘要】：液力變矩器與發(fā)動(dòng)機(jī)作為工程機(jī)械動(dòng)力傳動(dòng)系統(tǒng)的核心零部件，，它們之間的裝配質(zhì)量直接影響著動(dòng)力傳動(dòng)系統(tǒng)的性能。由于液力變矩器與發(fā)動(dòng)機(jī)的裝配質(zhì)量取決于液力變矩器內(nèi)孔裝配尺寸的測(cè)量準(zhǔn)確度，因此，該關(guān)鍵尺寸的測(cè)量尤為重要。 目前，液力變矩器內(nèi)孔裝配尺寸的主要測(cè)量方法是使用深度尺進(jìn)行人工手動(dòng)測(cè)量，該測(cè)量方法忽略了液力變矩器內(nèi)孔裝配累積誤差，導(dǎo)致裝配尺寸測(cè)量不準(zhǔn)確，最終影響了液力變矩器與發(fā)動(dòng)機(jī)的裝配精度。針對(duì)目前液力變矩器內(nèi)孔裝配尺寸測(cè)量存在的問(wèn)題以及制造商的實(shí)用需求，本課題以國(guó)家質(zhì)檢總局科技計(jì)劃項(xiàng)目“液力變矩器內(nèi)孔裝配尺寸測(cè)量裝置的研發(fā)”為背景，設(shè)計(jì)并研制了一種液力變矩器內(nèi)孔裝配尺寸測(cè)量裝置。 本文對(duì)該關(guān)鍵裝配尺寸作了尺寸鏈計(jì)算，并且分析了液力變矩器內(nèi)部的裝配累積誤差，為新的測(cè)量裝置的設(shè)計(jì)提供了理論依據(jù)。我們?cè)O(shè)計(jì)了一種通過(guò)施加壓力消除液力變矩器內(nèi)孔裝配累積誤差，同時(shí)間接測(cè)量出該裝配尺寸的測(cè)量裝置。該測(cè)量裝置采用了伺服控制技術(shù)、液壓傳動(dòng)技術(shù)、激光傳感技術(shù)和數(shù)據(jù)采集與處理等信息化管理技術(shù)。 測(cè)量裝置采用伺服電機(jī)和滾珠絲杠驅(qū)動(dòng)實(shí)現(xiàn)待測(cè)工件的精確定位，采用液壓系統(tǒng)對(duì)待測(cè)工件施加壓力以減小其內(nèi)部裝配累積誤差，采用激光位移傳感器進(jìn)行精確測(cè)量。上位機(jī)測(cè)量軟件采用C++語(yǔ)言編寫(xiě)，主要有數(shù)據(jù)讀取、數(shù)據(jù)分析、匹配處理、打印報(bào)表等功能，與下位機(jī)采用RS232串口進(jìn)行通信。 文章最后對(duì)測(cè)量裝置的可靠性進(jìn)行了分析和預(yù)計(jì)；對(duì)測(cè)量裝置的測(cè)量誤差因素進(jìn)行分析；通過(guò)測(cè)量實(shí)驗(yàn)驗(yàn)證測(cè)量裝置的可靠性并與傳統(tǒng)測(cè)量方法作比較。
[Abstract]:As the core parts of power transmission system of construction machinery, the assembly quality between hydraulic torque converter and engine directly affects the performance of power transmission system. Because the assembly quality of hydraulic torque converter and engine depends on the measurement accuracy of the assembly size of the inner hole of the hydraulic torque converter, the measurement of the key dimension is particularly important. At present, the main measuring method of the assembly size of the inner hole of hydraulic torque converter is manual manual measurement with depth ruler, which neglects the accumulative error of assembly of the inner hole of hydraulic torque converter, resulting in the inaccurate measurement of assembly size. Finally, the assembly accuracy of torque converter and engine is affected. In view of the problems existing in the measurement of the internal hole size of hydraulic torque converter and the practical requirements of the manufacturer at present, this subject is based on the scientific and technological project of the State Administration of quality Supervision and Inspection, "the Research and Development of the measuring device for the Assembly size of the Inner Hole of the hydraulic torque Converter". A device for measuring the assembly size of the inner hole of hydraulic torque converter is designed and developed. In this paper, the dimension chain of the key assembly is calculated, and the accumulative errors in the assembly of the torque converter are analyzed, which provides a theoretical basis for the design of the new measuring device. A measuring device is designed to eliminate the accumulative errors in the assembly of the inner hole of hydraulic torque converter by applying pressure, and indirectly measure the assembly size. Servo control technology, hydraulic transmission technology, laser sensing technology and data acquisition and processing are used in the measuring device. The measuring device uses servo motor and ball screw drive to realize the precise positioning of the workpiece to be tested. The hydraulic system is used to apply pressure to the workpiece to reduce the accumulative error of the internal assembly. The laser displacement sensor is used to accurately measure the workpiece. The measuring software of upper computer is written in C language, which has the functions of data reading, data analysis, matching and processing, printing report forms and so on, and communicates with the lower computer with RS232 serial port. Finally, the reliability of the measuring device is analyzed and predicted, the error factors of the measuring device are analyzed, and the reliability of the measuring device is verified by the measurement experiment and compared with the traditional measurement method.
