摘要

    隨著數(shù)控技術(shù)在機械零件加工中的飛速發(fā)展和日益及，數(shù)控機床及其工裝的設(shè)計和制造在確保機械零件的生產(chǎn)質(zhì)量和提高生產(chǎn)率、縮短新產(chǎn)品研究周期等方面越來越重要。數(shù)字化技術(shù)在機械零件加工與工裝的設(shè)計與制造正向自動化、通用化、標(biāo)準(zhǔn)化、數(shù)字化方向快速發(fā)展。在數(shù)控機床高度發(fā)展的今天，機床液壓電器控制程度越來越高，因此機床液壓傳動控制的地位于作用也日益重要。機床液壓自動控制的發(fā)展與液壓傳動的發(fā)展緊密相連。

本文從集液壓的角度出發(fā)，研究設(shè)計數(shù)控機床自動夾緊系統(tǒng)，對數(shù)控機床與液壓控制接口進行了研究，利用控制工藝裝備中的夾緊裝置實現(xiàn)裝置的卡盤夾緊、刀架回轉(zhuǎn)、尾套筒的伸出功能。

Abstract

Along with numerical control technology in the mechanical parts processing of rapid development and the growing and, nc machine tools and tooling design and manufacturing in ensure machinery parts production quality and productivity, shorten the cycle of new product research in more and more important. Digital technology in machinery parts processing and tooling design and manufacturing positive automation, generalization, standardization, digital orientation rapid development. In the numerical control machine tool of a highly developed today, machine tool hydraulic electrical control degree more and more high, so the status of hydraulic drive control machine tools in effect are becoming increasingly important. The development of automatic control hydraulic machine and hydraulic transmission development are closely linked

This paper, from the point of view of the hydraulic set, study design nc machine tools to be automatic clamping system, the numerical control machine and hydraulic control interface was studied, and the use of control process equipment clamping device to realize the chuck clamping device, knife, the tail of the sleeve turn out function.

For a axis machining parts design automatic clamping system of specific mechanical parts of the institutions, hydraulic transmission control circuit presented related part of the design.

Keywords: automatic clamping; Hydraulic transmission
