    • A positioning apparatus for positioning a test head for testing electronic components is provided. The positioning apparatus includes an outer cylinder and a support coupled to the outer cylinder for supporting the test head. The positioning apparatus also includes a piston arranged within said outer cylinder such that the piston and the outer cylinder define a fluid compartment within the outer cylinder. The positioning apparatus also includes a pressure regulator for maintaining a pressure within the fluid compartment such that the test head may be suspended in a substantially weightless position, the substantially weightless position being adjustable in a vertical direction. The positioning apparatus also includes a lifting device for raising and lowering the outer cylinder. The lifting device includes a threaded drive mechanism coupled to the piston. The positioning apparatus also includes a drive apparatus for operating the threaded drive mechanism to move the test head to a predetermined position.
    • 提供了一种用于定位用于测试电子部件的测试头的定位装置。 定位装置包括外筒和联接到外筒的支撑件,用于支撑测试头。 定位装置还包括设置在所述外筒内的活塞,使得活塞和外筒在外筒内限定流体隔室。 定位装置还包括用于保持流体隔室内的压力的压力调节器,使得测试头可以悬挂在基本上无重量的位置,基本上无重量的位置可在垂直方向上调节。 定位装置还包括用于升高和降低外筒的提升装置。 提升装置包括联接到活塞的螺纹驱动机构。 定位装置还包括用于操作螺纹驱动机构以将测试头移动到预定位置的驱动装置。

    • The invention relates to an electromotive linear drive (10), which contains a speed reduction gear unit that is coupled to a drive motor for driving a spindle (11), a spindle nut (13) being placed on said spindle (11). The linear drive (10) is additionally equipped with a braking assembly (14), in order to regulate the speed of the spindle (11). The aim of the invention is to configure said drive simply in such a way that it is no longer necessary to decouple the drive function of the drive unit, formed by the drive motor and the speed reduction gear, from the spindle (11). According to the invention, the spindle nut (13) is equipped with a braking assembly (14) that comprises a coil spring (17) and the force that is transmitted by the coil spring (17) to a component (16) lying in said spring can be controlled, to allow the speed of the spindle (11) to deviate from the normal speed. Said linear drive (10) is particularly suitable for displacing the mobile components of a piece of furniture.
    • 一电动的直线驱动器(10),其包含一个驱动马达,连接到其上的减速齿轮,用于驱动主轴(11),其特征在于,所述主轴(11)的主轴螺母(13)被装配,并且该线性驱动器(10)还设置有一个制动组件 配(14),以调节旨在被配备,使得在结构上简单的方式向驱动单元的驱动器的去耦和驱动马达和心轴(11)的减速齿轮构成可省去所述主轴(11)的速度。 根据本发明,所述主轴螺母(13)是一个具有一个卷绕弹簧(17)关断武装配备制动组件(14),其中,所述卷绕弹簧(17)一个位于其中的部件(16)上的可通过传递给主轴的旋转速度的力来控制 (11)偏离正常速度。 根据本发明的线性驱动器(10)特别适用于调节一件家具的可移动部件。
