    • PURPOSE: A system for detecting vibration and automatically adjusting speed of a spindle of a machine tool is provided to prevent vibration by the surface fault of material, the instability of equilibrium, chucking fault. CONSTITUTION: A system for detecting vibration and automatically adjusting speed of a spindle of a machine tool comprises a drive motor(102), a principal axis(104), a chuck(106), a sensor(110), and a controller(120). The principal axis is rotated by the driving force of the drive motor. The chuck is connected to the other end of the principal axis and fixes workpieces(W). The sensor senses the vibration of the principal axis and generates the oscillation detection signals. The controller gradually reduces the speed of rotation and the feeding speed of the principal axis.
    • 目的:提供一种用于检测机床主轴振动和自动调速的系统,以防止材料表面故障,平衡不稳定,夹紧故障引起的振动。 构成:用于检测机床的主轴的振动和自动调节速度的系统包括驱动马达(102),主轴(104),卡盘(106),传感器(110)和控制器(120) )。 主轴由驱动电机的驱动力旋转。 卡盘连接到主轴的另一端并固定工件(W)。 传感器感测主轴的振动并产生振荡检测信号。 控制器逐渐降低主轴的旋转速度和进给速度。

    • PURPOSE: A vibration detecting apparatus of a spindle belt for a machining center and a method thereof are provided to protect a spindle, and to prevent breakage of the machine tool by checking tension of the belt according to vibration of the spindle belt and stopping the spindle. CONSTITUTION: A vibration detecting device of a spindle belt comprises a vibration detecting unit(110) detecting vibration of the belt; an input setting unit(150) providing reference frequency data of the belt; and a control unit(140) comparing the belt frequency from the vibration detecting unit with the reference frequency from the input setting unit, and stopping operation of the machine tool by turning off a relay switch of an emergency circuit line at the measured frequency of the belt to be beyond the reference frequency. Breakage of the machine tool is prevented by checking the tension of the belt in rotating the belt.
    • 目的:提供一种用于加工中心的主轴带的振动检测装置及其方法,以保护主轴,并且通过根据主轴带的振动检查带的张力并且阻止主轴来防止机床的断裂 。 构成:主轴带的振动检测装置包括检测带的振动的振动检测单元(110) 提供所述带的参考频率数据的输入设置单元(150) 以及将来自振动检测单元的带频率与来自输入设定单元的参考频率进行比较的控制单元(140),并且以所测量的频率关闭紧急电路线路的继电器开关来停止机床的操作 皮带超出参考频率。 通过在旋转皮带时检查皮带的张力来防止机床的破损。
