(1)摇臂钻床运动部件较多,为了简化传动装置,采用多台电动机拖动。例如Z3040型摇臂钻床采用4台电动机拖动,他们分别是主轴电动机,摇臂升降电动机,液压泵电动机和冷却泵电动机,这些电动机都采用直接启动方式。
(1) There are many moving parts in radial drilling machine. In order to simplify the transmission device, several motors are used to drive. For example, Z3040 radial drilling machine is driven by four motors, they are spindle motor, rocker lifting motor, hydraulic pump motor and cooling pump motor, all of which are directly started.
(2)为了适应多种形式的加工要求,摇臂钻床主轴的旋转及进给运动有较大的调速范围,一般情况下多由机械变速机构实现。主轴变速机构与进给变速机构均装在主轴箱内。
(2) In order to meet the requirements of various forms of processing, the spindle rotation and feed movement of radial drilling machine has a large range of speed adjustment, which is usually realized by mechanical speed change mechanism. The spindle speed change mechanism and the feed speed change mechanism are installed in the spindle box.
(3)摇臂钻床的主运动和进给运动均为主轴的运动,为此这两项运动有一台主轴电动机拖动,分别经主轴传动机构,进给传动机构实现主轴的旋转和进给。
(3) The main motion and the feed motion of the radial drilling machine are all the movements of the main shaft. Therefore, the two movements are driven by a motor of the main shaft, and the rotation and feed of the main shaft are realized by the drive mechanism of the main shaft and the feed drive mechanism respectively.
(4)在加工螺纹时,要求主轴能正反转。摇臂钻床主轴正反转一般采用机械方法实现。因此主轴电动机仅需要单向旋转。
(4) When machining the thread, the spindle is required to be able to rotate forward and backward. Generally, the positive and negative rotation of the main shaft of radial drilling machine is realized by mechanical method. Therefore, the spindle motor only needs one-way rotation.
(5)摇臂升降电动机要求能正反向旋转。
(5) The rocker lift motor shall be able to rotate forward and backward.
(6)内外主轴的夹紧与放松、主轴与摇臂的夹紧与放松可用机械操作、电气—机械装置,电气—液压或电气—液压—机械等控制方法实现。若采用液压装置,则备有液压泵电机,拖动液压泵提供压力油来实现,液压泵电机要求能正反向旋转,并根据要求采用点动控制。
(6) The clamping and relaxation of the internal and external spindles, and the clamping and relaxation of the spindles and rocker arms can be realized by mechanical operation, electrical mechanical device, electrical hydraulic or electrical hydraulic mechanical control methods. If the hydraulic device is used, a hydraulic pump motor is equipped, which is driven to provide pressure oil. The motor of the hydraulic pump shall be able to rotate forward and backward, and shall be controlled by inching according to the requirements.
(7)摇臂的移动严格按照摇臂松开→移动→摇臂夹紧的程序进行。因此摇臂的夹紧与摇臂升降按自动控制进行。
(7) The movement of the rocker arm is strictly in accordance with the procedure of loosening → moving → clamping the rocker arm. Therefore, the clamping and lifting of the rocker arm are carried out according to the automatic control.
(8)冷却泵电动机带动冷却泵提供冷却液,只要求单向旋转。
(8) The cooling pump motor drives the cooling pump to provide coolant, which only requires one-way rotation.
(9)具有连锁与保护环节以及安全照明、信号指示电路。
(9) It has interlocking and protection links as well as safety lighting and signal indicating circuits.
