Embodiment Construction

[0039] figure 1 A side view of the device with workpiece 32 clamped between upper tip 33 and lower tip 23 in device 10 is shown. The toothed part of this workpiece 32 is machined with a machine tool 31 , which in this case is a grinding worm. For this purpose, the machine tool 31 is moved parallel to the axial direction of the workpiece 32 with different center distances in one or more cycles and thus produces or processes the gear connection.

[0040] For machining purposes, a workpiece is loaded onto the apparatus 10 with a loading system (not shown) or manually, and the workpiece 32 is clamped on the apparatus between the upper and lower tips 23 by lowering the upper tip 33 . In other axial arrangements, for example, the entire device 10 may be arranged horizontally.

[0041] The workpiece 32 is initially centered between the tips 23, 33 before the drive mechanism member 25 is actively applied in the further process. Thus, the best concentricity of the workpiece 32 is ac...

Abstract

The invention relates to a device for rotatably clamping a workpiece between two top ends, the device is arranged on a machine tool workbench of a machine tool, the device comprises: a top end body which is arranged in the middle and a plurality of driver components which are concentrically arranged, are movable in axial direction and can be pressed on the end face surface or pressed in the end face surface for rotation and clamping of the workpiece, wherein the axial position of the driver components can be limited by actively fixing after the centring operation of the workpiece. The invention also relates to a container relative to the body, such as a top end or a hollow top end, and the container can guide the opposite side of the workpiece.

Description

technical field [0001] The invention relates to a device for rotary entrainment of a workpiece clamped between two tips, mounted on a machine table of a machine tool, comprising: a body with a centrally arranged tip; and a plurality of Concentrically arranged, axially displaceable drive mechanism member pressed against or into the end face surface for rotational entrainment of the workpiece, wherein the axial position of the drive mechanism member can be controlled by the centering operation of the workpiece Actively fixed to limit. The invention also relates to a housing opposite the body, such as a tip or a hollow tip, which functions to guide the opposite side of the workpiece. Background technique [0002] A machine tool may preferably be a machine for manufacturing or machining gears. [0003] Such devices are commonly known as face drivers or end drivers, and are preferred for vibrating workpieces that have no or insufficient workpiece holes through which the workpie...
