臥式單面多軸鉆孔組合機床動力滑臺液壓系統的設計

系統說明

1、設計要求及工況分析

（1）設計要求

設計一臺臥式單面多軸鉆孔組合機床動力滑臺的液壓系統（含圖）。動力滑臺的工作循環是：快進→工進→快退→停止。液壓系統的主要參數與性能要求如下：切削力Ft=20000N，移動部件總重力G=10000N，快進行程=100mm，工進行程=50mm，快進快退的速度為4m/min，工進的速度為0.05m/min；加速、減速時間=0.2s，靜摩擦系數=0.2，動摩擦系數=0.1。該動力滑臺采用水平放置的平導軌，動力滑臺可在任意位置停止。

（2）工況分析

首先根據已知條件繪制運動部件的速度循環圖，如圖1所示，然后計算各階段的外負載并繪制負載圖。

①液壓缸所受的外負載F包括三種類型，即

式中 ——工作負載，對于金屬切削機床來說，即為沿活塞運動方向的切削力，在本設計中為20000N；

???? ——導軌摩擦阻力負載，啟動時為靜摩擦阻力，啟動后為動摩擦阻力，對于平導軌可由下式求得

G——運動部件重力；

——垂直于導軌的工作負載，本設計中為零；

f——導軌摩擦系數，在本設計中靜摩擦系數為0.2，動摩擦系數為0.1。則求得

上式中為靜摩擦阻力，為動摩擦阻力。

???? ——運動部件速度變化時的慣性負載；

式中 g——重力加速度；

???? ——加速或減速時間，本設計中

???? ——時間內的速度變化量。

在本設計中????????????
