隨著機(jī)械制造業(yè)的不斷發(fā)展，社會(huì)對(duì)生產(chǎn)率的要求也越來(lái)越高。因此，大批量生產(chǎn)成為時(shí)代的需求，而組合機(jī)床就可以滿足這一需求，我們有必要來(lái)研究它。
本文中利用組合機(jī)床將銑端面和打中心孔在同一道工序中完成，這樣可以避免工件在加工不同工序時(shí)由于夾緊定位而產(chǎn)生的定位誤差。根據(jù)所擬定的組合機(jī)床的工藝和結(jié)構(gòu)方案，可以定下夾具的結(jié)構(gòu)形式和主要性能。夾具設(shè)計(jì)的要點(diǎn)是：確保夾具有足夠的剛度和強(qiáng)度，降低夾具的重心來(lái)提高夾具的穩(wěn)定性；避免加工時(shí)發(fā)生振動(dòng)；夾緊裝置有足夠的夾緊力和良好的自鎖性能；注意采用快速夾緊、聯(lián)動(dòng)夾緊、氣動(dòng)液壓夾緊裝置和機(jī)械化傳動(dòng)裝置等。

Title Design of Combined Machined Tool and Special Fixture for Milling the End face and Punching the Central Hole on the Crankshaft
Abstract
With the continuous development of the machine manufacturing industry, the productivity of the community's increasing demands.Therefore, high volume production needs of the times, and the combination is enough to meet the needs of machine tool. We need to study it. In this paper,the use of combined machine tool can complete milling the end suferface and punching the central hole at the same procedure. This will avoid the workpiece in different processes arising positioning error as a result of clamping the positioning. According to the combined machined tool technology and the structure that have been studied out, and then the structure and the main properties can be set. The dist of fixture design: Ensure the fixture have sufficient stiffness and strength;Reduce the fixture's center of gravity to improve the stability of fixture. To avoid vibration when machining. Clamping device has sufficient clamping force and a good performance of the self-locking. Attention to the use of rapid clamping, clamping linkage,Hydraulic clamping devices and mechanical transmission devices etc.
