摘要： A polishing apparatus in which one of two workpieces to be polished or abraded which contact each other at respective arcuate or spherical surfaces, is placed on a fixed base and turned or fixed in a horizontal plane with the other workpiece held under pressure by a retainer provided on a gate type frame which can be swung around the center of curvature of the contact surfaces of the two workpieces by a swinging unit capable of varying the range of swinging movement of the gate-type frame. The center of the swinging movement of this frame can be varied by changing the position of two pivot-connected block units vertically in a stepless manner and the position of the retainer to a reference axis can be varied. This enables the apparatus to be applied to workpieces having arbitrary curved surfaces to be polished and of different dimensions.

摘要： An apparatus for displacing a line of track chain is disclosed which is employable for the purpose of disassembling, assembling, or reassembling the chain. A guide table for guiding movement of the chain is adapted to tilt only in the upward direction together with a pair of rails which are raised or lowered by actuating a first cylinder. A trolley moves forward and backward in the space as defined by both the rails by actuating a second cylinder while it is guided along the rails. The trolley is provided with an engagement rod which extends upwardly therefrom through a slot on the guide table to come in engagement to a bushing in the chain. Forward displacing of the chain is achieved by way of the steps of tilting up the guide table together with the rails by actuating the first cylinder, displacing the trolley forward by a distance equal to one pitch of the chain by actuating the first cylinder, lowering the rails to the lowermost position by retracting the first cylinder and displacing the trolley backward to the initial position by retracting the second cylinder. A distance of displacement of the chain is adjustably determined by selectively determining the position of two stoppers on a stationary screw spindle which is extended below the rails in parallel to the latter. Each of the stoppers is adapted to abut against an abutment member fixedly secured to the bottom of the trolley.
摘要翻译： 公开了用于移动轨道链条的装置，其用于拆卸，组装或重新组装链条的目的。 用于引导链条运动的引导台适于仅在向上的方向上倾斜，以及通过致动第一缸而升高或降低的一对轨道。 在由两个轨道限定的空间中，小车在沿着轨道被引导的同时致动第二气缸而向前和向后移动。 手推车设置有接合杆，该接合杆从其上向上延伸穿过导向台上的槽，以与链条中的衬套接合。 通过以下步骤实现链条的向前位移：通过致动第一气缸将引导台与轨道一起向上倾斜的步骤，通过致动第一气缸将手推车向前移动等于链条的一个间距的距离， 通过缩回第一气缸并通过缩回第二气缸将推车向后移动到初始位置而导向最低位置。 通过选择性地确定固定螺杆上的两个塞子的位置可调整地确定链条的位移距离，该固定螺杆主轴平行于导轨的下方延伸。 每个止动件适于抵靠固定地固定在手推车底部的抵接件。

摘要： A hydraulic shoe bolt wrench used to mount and remove shoe bolts which secure shoes to a track chain. The apparatus comprises a vertical cylinder stood upright on a frame moving on a work table, a main frame secured to a piston rod of the vertical cylinder, a wrench socket driving shaft vertically projected below the main frame, a low speed high torque motor and a reduction gear provided on the driving shaft. Pressure oil is supplied to the high speed low torque motor and high pressure oil is supplied to the low speed high torque motor. Switching of the high speed low torque motor to the low speed high torque motor is carried out by a pressure switch disposed in a low pressure hydraulic circuit.

摘要： An apparatus for assemblying link chains of the type having paired links joined together with cross pins joining successive pairs of links longitudinally as chain links having a pitch corresponding to the distance between successive cross pins connecting the paired links. The apparatus has a pair of opposed presses each having a corresponding ram head. The ram heads are cylically operated from a retracted starting position and advanced toward each other and retracted to their retracted position. The ram heads are provided with tools on tool bars for transporting and assemblying paired links on successive cross pins. A trolley travels between the ram heads in a diection forwardly three half pitches and then in a reverse direction two half pitches. The trolley upon reaching the second reverse half-pitch returns to the forward movement of its next operating cycle. The trolley advances successive individual cross pins spaced along the path of travel and thus transports the link chain assembly. The tools on the ram heads position the links onto opposite ends of stationary two successive cross pins as paired links. The links are held in assembly on the cross pins by retainer rings fixed on opposite ends of the cross pins when the cross pins are stationary at the end of the reverse or backward movement of one half pitch by the trolley.
摘要翻译： 用于组装具有成对连杆的类型的链节的装置，其中交叉销将连续的连续对的链条纵向连接成链节，链节具有对应于连接成对链节的连续十字销之间的间距的间距。 该装置具有一对相对的压力机，每个压力机具有相应的压头头部。 压头头部从缩回的起始位置进行环形操作，并且朝向彼此前进并缩回到其缩回位置。 柱塞头在工具杆上设有工具，用于在连续的十字销上运输和组装成对的连杆。 手推车在压头之间行进，前后三个半间距，然后相反方向两个半间距。 手推车到达第二个反向半间距时，返回到下一个运行周期的向前运动。 手推车沿着行进路径前进连续的单个十字销，从而运输链节组件。 柱塞头上的工具将连杆定位成固定的两个连续的十字销的相对端，作为成对的连接。 当十字销在手推车的一个半间距的反向或向后移动的结束处固定时，通过固定在十字销的相对端上的保持环将链节保持在十字销上。
