Problems solved by technology

Despite the significant control complexity, it is still unavoidable that there will be speed differences between the drive elements connected to the servo motors, and the transmission on the sliding sleeve often collides with the transmission on the drive element, with the result that either engagement or is impossible, or is possible only to a limited extent
This leads to blockages, and operational blockages or disturbances leading to interruption of the processing sequence are therefore often unavoidable

Embodiment Construction

[0032] figure 1The clamping device shown in and identified by 1 is used to actuate a power-operated chuck 3 arranged on a machine tool 2, by means of its radially adjustable clamping jaws 4, a workpiece 10 to be processed can be clamped in Chuck 3. The clamping jaws 4 of the power-operated chuck 3 can in this case be actuated via a relay operating lever 7 by an axially movable draw rod 6 in driving connection with an electric servomotor 12 , said The electric servomotor 12 has a switching function by means of the drive element 261 and the movement converter 231 . The rotational adjustment movement of the servo motor 12 is converted into an axial feed movement of the tie rod 6 by means of a movement converter 231 inserted in a housing 219 which is firmly connected to the machine tool spindle 5 .

[0033] The servomotor 12 is in this case connected to a drive element 261 by means of a V-pulley 14 arranged on its rotor shaft 13 and a toothed or drive belt 15 , which in this cas...

Abstract

A coupling fixture for reciprocal connection between two components rotating in opposite directions to one another, with a drive element and an axially adjustable coupling element in a rotationally fixed connection with the drive element or one of the two components. The two components are locked together directly, or by the coupling element, and the locking is released by moving the coupling element axially. Thereby rendering it possible to establish connection without the need for special controls and / or synchronisation of the components to be connected. Switching operations can be performed when the drive element and the coupling element are being driven with different speeds of rotation. It is thus possible to achieve a reliable and trouble-free operating method of the coupling fixture over a long period of time.

Description

technical field [0001] The invention relates to a device for reciprocating connection between two components arranged on a drive element by means of an axially adjustable coupling element and rotating in opposite directions to each other, in particular for electric clamping The drive element is connected to it, so that the rotational adjustment movement of the drive element can be converted into an axial adjustment movement. Background technique [0002] As disclosed in EP 2384839 B1, in an electric clamping device for machine tools, in order to convert the adjustment movement of the rotor shaft of the servo motor into the axial adjustment of the tie rod required for actuating the clamping jaws of the power-operated chuck movement, there are measures to connect the servo motor by means of a controllably adjustable sliding sleeve via an intermediate link and a transmission to the motion converter in the clamping position of the clamping device. In the operating position, how...
