摘要：本設(shè)計課題來源于江蘇恒力組合機床有限公司。底板是需要大量生產(chǎn)的零件，為了提高加工精度和生產(chǎn)效率，需要設(shè)計一種液壓自動夾緊的組合機床來改善底板的加工情況。本組合機床是針對底板下平面的半精加工的需要而設(shè)計的。該設(shè)計的內(nèi)容包括總體設(shè)計和夾具設(shè)計兩方面。在總體設(shè)計中分析了被加工零件的加工工藝性，選擇了加工的定位基準及夾緊方案，合適的切削用量、刀具、及機床的配置型式，合適的結(jié)構(gòu)方案等，同時完成了“三圖一卡”的繪制。在夾具設(shè)計方面，采用了專用夾具，用符合六點定位原則的“三平面”定位方案消除工件的六個自由度，使工件獲得穩(wěn)定可靠的定位，并可以同時加工兩個零件，能高度集中工序。夾緊裝置則選用比較安全、可靠、方便的液壓夾緊裝置，使夾緊平穩(wěn)可靠。本組合機床效率高，成本低，加工精度高，操作使用方便，減輕了工人的勞動強度，提高了勞動生產(chǎn)率，滿足了設(shè)計需要。

The Design of Overall and Fixture for YZJ1956 Machine Tool
Abstract: The design project is from HenLi Dynamic Group, Yancheng. The bottom board is the part needing to be produeed numerously.In order to improve the accuency and efficiency,we should design a combination lathe that can hold automatically by hydraulic pressure to ameliorate the working condition of bottom board.This combination lathe is designed for the half-precision work for the plane beneath the bottom board.The design is mainly focused on both the overall design and jig design. The overall design makes detailed analysis of processing techonology, choice of the positioning datum of processing, grip program, proper cutting parameters, cutting tools, the configuration types of machine tools, the proper construction program and so on. Meanwhile the drawing of ‘Three Charts and One Card’ (automatic drawing process chart, size relation chart, machining schematic diagram and production calculating card) are completed. As far as jigs are concered, a special fixture are employed with the aid of the three platforms positioning program according to the principle of six points positioning to eliminate the six degrees of freedom of workpiece for a stable and reliable positioning, and the synchronous processing of two surfaces of parts which can simplifying the process. The safer, more reliable and convient hydraulic grip devices are employed for a stable and reliable grip. The charateristics of efficiency, low cost, high processing accuracy, easy operation, The machine tool is obtained to relieve the labor internsity, improve efficiency which meets the requirements of the design.
