Abstract

本发明公开了一种机床旋转工作台,属机床零部件。它包括回转台、滑台、滑座、进给蜗杆、进给蜗轮、进给丝杆、传动电机,其与进给蜗杆同轴设置有回转蜗杆,中间加装换向离合器连接;回转蜗杆与安装在回转中心轴上的回转蜗轮相配匹。其采用同轴双蜗杆机构,由换向离合器调节控制,同一台电机驱动进给和旋转。结构简单,定位准确,传动精度可靠,可明显提高机床加工精度。

Description

一种机床旋转工作台
技术领域
本发明涉及机床零部件,具体说是一种机床旋转工作台。
背景技术
旋转工作台是机床上用于装夹加工工件的装置,现有机床旋转工作台普遍采用多轴联动,进给和旋转分开的传动方式,其结构复杂,且传动振动大,定位精度低,因此严重影响机床加工精度。
发明内容
本发明的目的是采用同轴双蜗杆机构,提供一种定位准确,传动精度高的机床旋转工作台。具体技术方案是:一种机床旋转工作台,包括回转台、滑台、滑座、进给蜗杆、进给蜗轮、进给丝杆、传动电机,其与进给蜗杆同轴设置有回转蜗杆,中间加装换向离合器连接;回转蜗杆与安装在回转中心轴上的回转蜗轮相配匹。
本发明的优点是:采用同轴双蜗杆机构,由换向离合器调节控制,同一台电机驱动进给和旋转。其结构简单,定位准确,传动精度可靠,可明显提高机床加工精度。
附图说明
图1为本发明横向剖面图。
图2为本发明纵向剖面图。
图中:1为回转蜗杆,2为回转蜗轮,3为回转中心轴,4为回转台,5为滑台,6为滑座,7为进给蜗杆,8为进给蜗轮,9为进给丝杆,10为换向离合器,11为传动电机,12为手动摇柄。
具体实施方式
如图1、2所示,本发明是对现有工作台的改进,同样具有滑台5、滑座6、进给蜗杆7、进给蜗轮8、进给丝杆9、回转台4、回转中心轴3,不同的是与进给蜗杆7同轴安装有回转蜗杆1,中间连接换向离合器10。接换向离合器10通常用拔杆操控。转蜗杆1与安装在回转中心轴3上的回转蜗轮2配匹。从而实现进给和旋转由同一台传动电机11驱动。另外设有手动摇柄12微调。
