组合镗动力头设计
摘 要
在大批量生产中经常用到组合镗床,本次设计的组合镗床动力头,就是实现快速加工的好方法.它是利用床身后的液压缸推动床身到达工件旁.然后另一液压缸推动旋转主轴镗孔,同时主轴上的齿条带动齿轮转动,和其同轴的另一齿轮带动滑板上的齿条径向进给,车端面.
机床的主要特征是:工件在加工过程中保持静止,所有造型运动都施加到刀具上.通过旋转刀具来实现镗削,刀具安装在接到主轴上的镗杆上,然后沿旋转轴线进给主轴,镗杆和刀具.端面车削工序可以通过使用专用刀具架在其旋转时径向进给刀具来实现.
与一般的动力头相比此动力头的优点是
1).一次走刀可以加工多个加工面,不但节约时间,而且保证零件的加工精度.(2).自动化程度高,工人的劳动强度低.(3).制造与安装简单,所需的夹具复杂程度低.

Combination boring power unit design
Abstract
Usually use the combination-boring machine in quantity production, the combination boring machine power unit of this design, is a good method that realizes fly-process. It is the hydro-cylinder to make use of the after body section push the body section arrive the work a beside. Then another hydro-cylinder pushes to revolve the main spindle borehole, the rack on the main spindle arouses the gear running at the same time, sum its coaxial another gear arouses rack on the slide plate a radial feed, turning end surface.
The principal feature of the machine is that the workplace remains stationary during machining, and all the generating motions are applied to the tool. Boring is achieved by rotating the tool, which is mounted on a boring bar connected to the spindle, and then feeding the spindle, boring bar, and tool along the axis of rotation. A facing operation can be carried out by using a special tool holder that feeds the tool radically as it rotates.
Comparing with the ordinary power unit the advantage of this power unit is: (1) One pass can process machined surface more, not only economize time, but also guaranteeing the parts machining accuracy. (2). The automation degree is high, the worker's labor strength is low. (3). Production and installation simple, a fixture for needing grip the degree is low.
Key Words: Radial feed. Axial feed. One pass. Simultaneously. Main spindle. Rack-and-pinion.
