車(chē)床變速用撥叉是某企業(yè)產(chǎn)品的主要零件之一。于是需要設(shè)計(jì)關(guān)鍵工序的專(zhuān)用夾具及加工用組合機(jī)床，而且?jiàn)A具采用液壓驅(qū)動(dòng)，組合機(jī)床采用液壓滑臺(tái)。工藝設(shè)計(jì)以保證質(zhì)量穩(wěn)定、生產(chǎn)可靠為原則。對(duì)工件進(jìn)行加工時(shí)，為了保證加工要求，首先要使工件相對(duì)于刀具及機(jī)床有正確的位置，并使這個(gè)位置在加工過(guò)程中不因外力的影響而變動(dòng)。為此，在進(jìn)行機(jī)械加工前，首先要將工件裝夾好。用夾具裝夾工件有下列優(yōu)點(diǎn)：能穩(wěn)定地保證工件的加工精度；能提高勞動(dòng)生產(chǎn)率；能擴(kuò)大機(jī)床的使用范圍；能降低成本。

Title Variable-speed lathe processing with fork and
key process equipment design
Abstract
Variable speed lathe with a fork is the product of one of the main parts. So the key processes necessary to design a special fixture and the combination of processing machine tools, fixtures and the use of hydraulic drives, hydraulic slide combination of the use of Taiwan machine tool. Process design to ensure stable quality, reliable production of principle. Processing of the workpiece, the processing requirements in order to ensure, first of all to the workpiece and the machine tool relative to a correct position, and this location is not in the process due to the impact of external changes. To this end, during the pre-machining the first workpiece to a good setup. Workpiece clamping fixture with the following advantages: can guarantee the stability of the machining accuracy of workpiece; will increase labor productivity; to expand the use of machine tools; to reduce costs.
