结构特点 / STRUCTURAL FEATURES
机床采用T型布局形式,在立柱的导轨上装有拖板,导轨中间位置装有垂直进给机构,传动精度高，互换性好,在传动过程中用十字接头连接,可补偿丝杠与减速器轴的中心误差。工作台移动采用闭式液压系统,前后进给可手动进给,液压自动进给或变频电机带动丝杆自动间歇进给,磨头上下移动为机动快速升降和手动进给两种方式。采用高强度铸铁基础件,磨头主轴采用筒子瓦或高刚性套筒结构,机床整体刚性强,品质稳定,运行平稳。
The machine tool adopts the t-type layout form, the guide rail on the column is equipped with a drag plate, the middle position of the guide rail is equipped with a vertical feed mechanism, the transmission accuracy is high, the interchangeabil- ity is good, the cross joint is connected in the transmission process, can compensate the center error of the lead screw and the reducer shaft. Closed hydraulic system is adopted for the movement of the worktable. The front and rear feed can be manually fed, the hydraulic feed can be automatically fed, and the lead screw can be fed automatically intermittently driven by a variable frequency motor. Adopt high strength cast iron foundation, grinding head spindle adopt bobbin or high rigidi- ty sleeve structure, the machine overall rigidity is strong, the quality is stable, the operation is stable.
技术参数 / TECHNICAL PARAMETERS
注: M7140、M7150A、 M7163规格平面磨床均可选择B型(主轴中心线至台面距离1000mm )或C型(主轴中心线至台面距离1400mm) , 其它参数与A型相同(机床高度及净重除外)。
Note: the surface grinding machines of M7140, M7150 and M7163 can be either type B (the distance from the center line of the spindle to the table is 1000mm) or type C (the distance from the center line of the spindle to the table is 1400mm), other parameters are the same as type A (except the height and net weight of the machine).
