    • The invention relates to a tool head for use in machine tools. The tool head has a basic body (10), a tool spindle (28) projecting axially above the basic body and connectable to a machine spindle, at least one working slide adjustable transversely to the axis (12) of the basic body and an adjusting motor (24) fitted in the basic body and acting on the working slide (16) in its adjustment direction via driving means (22, 72, 74, 68). To obtain a compact, easily assembled and reliable structure, the invention proposes that the driving means have an output shaft (72) running coaxially with the basic body and bearing a drive pinion (74) meshing with a rack (68, 124) on the working slide side. A further improvement in this respect is obtained if the adjusting motor (24) is fitted with a drive shaft (84) aligned with the output shaft (72) on the drive side. To improve ease of assembly, the tool head consists of three units which can be releasably assembled at axial separation points (30, 32), a slide unit containing the working slide (16), a drive unit (36) containing the adjusting motor and drive system and a connection unit (38) containing the tool shaft (28) and the power supply device (26).
    • 本发明涉及一种工具头用于在机床使用。 该工具头包括一个基体(10),轴向在基体伸出,可连接到机床主轴工具柄(28),至少一个横向于基体轴线(12)可调节工作滑动件和一个布置在基体,通过传输装置(22,72,74, 68)(在调整到工作滑动作用16)调节电机(24)。 实现紧凑的,容易地安装和可靠的结构,它是根据本发明,所述传动装置包括一个同轴地对准到基体轴输出轴有(72),载有与工作滑动侧齿板(68,124)啮合的驱动小齿轮(74)提出的。 当调整电机(24)具有发送侧与输出轴(72)对准的输出轴(84),获得在这方面的进一步改进。 为了提高易工具头可拆卸地连接到彼此的组件的三个在轴向分离点(30,32)组件组成,包含工作滑动件(16)滑动组件中,所述调整用电动机和所述传动装置包括驱动组件(36)和所述工具柄(28) 和电源装置,其包含(26)的连接组件(38)。

    • A cross-feed facing unit for use on a multiple spindle head machine tool includes a frame (28) into which a hollow bore spindle (40) is rotatably journaled. Integrated to the end of the spindle (40) distal from the fram (28) is a flange fastened to which is a housing (36). The housing has a slot or channel (92) inscribed therein which extends diametri­ cally across the housing so as to be in communication with the spindle bore (78). A tool-carrying cross-feed facing slide (97) is disposed in the channel (92), in the housing (36) and is reciprocated diametrically across the housing by a drawbar (108) disposed in the spindle bore (78). When the drawbar (108) is reciprocated along the axis by the motor (152) under numerical control, the drawbar (108) rotatably drives a set of pinion gears (106a, 106b, 106c, 106d) each journaled in the bore (78) of the spindle (40) so that one of the pinion gears (106a) meshingly drives a rack (102) on the underside of the slide (97) to bias the rack and the slide within the housing channel (92).
    • 在多主轴头机床上使用的交叉进给面单元包括框架(28),空心孔心轴(40)可旋转地嵌入该框架中。 与框架(28)远离的主轴(40)的端部一体地被固定在壳体(36)上。 壳体具有插入其中的槽或通道(92),其沿径向延伸穿过壳体以与主轴孔(78)连通。 面向工具的交叉进给滑动件(97)设置在壳体(36)中的通道(92)中,并且通过设置在主轴孔(78)中的牵引杆(108)沿径向往复运动。 当牵引杆(108)在数字控制下通过马达(152)沿轴线往复运动时,牵引杆(108)可旋转地驱动一组每个轴颈(78)中的小齿轮(106a,106b,106c,106d) ,使得一个小齿轮(106a)啮合地驱动滑块(97)的下侧上的齿条(102),以将齿条和滑动件偏置在壳体通道(92)内。
