万能升降台铣床主要结构特点
1、万能升降台铣床底座、机身、工作台、中滑座、升降滑座等主要构件均采用高强度材料铸造而成,并经人工时效处理,保证机床长期使用的稳定性。万能升降台铣床(7张)2、机床主轴轴承为圆锥滚子轴承,万能铣床主轴采用三支承结构,主轴的系统刚度好,承载能力强,且主轴采用能耗制动,制动转矩大,停止迅速、可靠。
3、工作台水平回转角度±45°,拓展机床的加工范围。万能铣床主传动部分和工作台进给部分均采用齿轮变速结构升降台,调速范围广,变速方便,快捷。
4、工作台X/Y/Z向有手动进给、机动进给和机动快进三种,万能铣床进给速度能满足不同的加工要求;快速进给可使工件迅速到达加工位置,加工方便、快捷,缩短非加工时间。
5、万能升降台铣床X、Y、Z三方向导轨副经超音频淬火、精密磨削及刮研处理,配合强制润滑,提高精度,延长机床的使用寿命。
6、润滑装置可对纵、横、垂向的丝杠及导轨进行强制润滑,减小机床的磨损,保证机床的高效运转;同时,万能铣床冷却系统通过调整喷嘴改变冷却液流量的大小,满足不同的加工需求。
7、万能铣床机床设计符合人体工程学原理,操作方便;万能铣床操作面板均使用形象化符号设计,简单直观。
8、床身用来固定和支承铣床各部件。顶面上有供横梁移动用的水平导轨。前壁有燕尾形的垂直导轨,供升降台上下移动。内部装有主电动机,主轴变速机构,主轴,电器设备及润滑油泵等部件。
9、横梁横梁一端装有吊架,用以支承刀杆,以减少刀杆的弯曲与振动。横梁可沿床身的水平导轨移动,其伸出长度由刀杆长度来进行调整。
10、主轴是用来安装刀杆并带动铣刀旋转的。主轴是一空心轴,前端有7:24的精密锥孔,其作用是安装铣刀刀杆锥柄。
11、纵向工作台纵向工作台由纵向丝杠带动在转台的导轨上作纵向移动, 以带动台面上的工件作纵向进给。台面上的 T形槽用以安装夹具或工件。
12、横向工作台横向工作台位于升降台上面的水平导轨上,可带动纵向工作台一起作横向进给。
13、转台转台可将纵向工作台在水平面内扳转一定的角度(正、反均为0~45o),以便铣削螺旋槽等。具有转台的卧式铣床称为卧式万能铣床。
14、升降台可以带动整个工作台沿床身的垂直导轨上下移动, 以调整工件与铣刀的距离和垂直进给。
15、底座底座用以支承床身和升降台,内盛切削液。
Universal milling machine main structure characteristics1, universal milling machine base, body, work table, in the slide, a lifting slide and other major components are made of high strength materials cast, and treatment by the artificial aging, ensure the stability of the machine tool used for a long time.Universal milling machine (7) 2, machine tool spindle bearings for tapered roller bearing, with three supporting structure of universal milling machine spindle, spindle system, good rigidity, strong bearing capacity, and the spindle adopts dynamic braking, braking torque, rapid, reliable stop.3, table level rotary angle of ± 45 °, expand the scope of the processing machine. Universal milling machine main transmission part and work table part adopts gear transmission structure lifting platform, wide speed range, speed and convenient, fast.4, table X\/Y\/Z to manual feed, mobile feed and motor in three, universal milling machine feed speed can meet the different requirements of processing; rapid feed can make the workpiece quickly arrived at the working position, convenient and rapid processing, shortening the processing time.5, universal milling machine X, Y, Z three direction guide through the super audio quenching, precision grinding and scraping treatment, with forced lubrication, improve accuracy, extend the service life of the machine.6, lubrication device for vertical, horizontal, vertical screw and guide rail to the forced lubrication, reduce the tool wear, to ensure efficient operation of machine tools; at the same time, universal milling machine cooling system by adjusting the nozzle change coolant flow size, to meet the processing requirements of different.7, universal milling machine tool design accord with human body engineering principle, convenient operation; universal milling machine operation panel using the image symbol design, simple and intuitive.8, the used components are fixed and supported milling machine. The top horizontal guide rail for beam moving with surface. The anterior wall of the vertical guide dovetail, for mobile lifting platform. Installed inside the main motor, the spindle speed, spindle, electrical equipment and lubricating oil pump etc.. 9, the beam beam end is provided with a hanger, to support the knife rod, in order to reduce the bending and vibration of the tool bar. The horizontal guide rail mobile beams along the bed, the extended length is composed of a knife rod length to be adjusted. 10, the spindle is used to install the tool bar and drive the cutter rotation. Main shaft is a hollow shaft, front-end precision taper of 7:24, its role is to install the cutter bar taper shank. 11, a longitudinal worktable workbench longitudinal direction by the screw drives the turntable rail for vertical movement of the upper, to drive the workpiece table for vertical feed. To install the fixture or work with a T shaped groove on the table. The horizontal guide rail 12, horizontal table horizontal table in the table above, can drive the vertical table with lateral feed. 13, turntable turntable to the vertical table in the horizontal plane pull turn a certain angle (positive, negative was 0 ~ 45o), so that the spiral groove milling etc.. With horizontal milling machine table called horizontal universal milling machine. 14, the lifting platform can lead the whole table along the bed of the vertical guide rail to move up and down, to adjust the workpiece and cutter distance and vertical feed. 15, the base base to support the body and the lift table, filled with cutting fluid.
