摘要： A vertical multiple-spindle machine relating to metal cutting machines. This machine comprises a stationary column on which is installed a rotary worktable mounting hydraulic clamping devices and provided with fluid inlet ducts. The stationary column is provided with passages for feeding fluid medium to he hydraulic clamping devices through said ducts, with the worktable in a fixed position. The column is also provided with a circular groove which is arranged to communicate with the fluid source and is formed so that it has portions curved about the outlets from the passages whereby said groove connects the worktable fluid ducts with the fluid source during the rotation of the worktable. This constructional arrangement makes it possible to materially reduce fluid leakage, thereby providing stability of the required fluid pressure in the clamping devices, improving the accuracy of the machine and decreasing waste of power.

摘要： An antifriction thrust bearing for a rotary table is constituted by a double-row bearing having an intermediate race rigidly connected through dimensioned inserts with a portion of the rotary table which is uppermost when in the working position, while the outer or upper and lower races are mounted on the lathe pillar relative to which the table rotates, with the upper race being capable of an axial displacement in a direction towards the lower race. The invention can be most effectively used in vertical multispindle lathes.

摘要： A device comprising horizontal and vertical shafts wherein the horizontal one is connected to a handle while the vertical shaft is operatively connected to a movable member of the clutch. Geometrical axes of said shafts are lying in a common plane, whereas shafts for transmitting rotation from the horizontal shaft to the vertical one are interconnected through a Geneva mechanism with a driving member of said mechanism being fixed to the horizontal shaft while a driven member thereof is fixed to the vertical shaft. It is possible with such an arrangement of the device to reduce the force applied by an operator of the machine tool to the clutch control handle.
