Abstract
A device for machining rolling element pockets in a workpiece includes a workpiece support, a main spindle, a clamping means fastened to the main spindle, a pressure cylinder and a machining tool. The clamping means includes a receiving arrangement for fastening the clamping means to the main spindle and a pressure plate for pressing the workpiece on the workpiece support. The pressure plate has a passage opening. The pressure cylinder connects the receiving arrangement to the pressure plate. The pressure cylinder is arranged to provide a force to adjust a contact pressure of the pressure plate on the workpiece. The machining tool is fastened to the main spindle and guidable through the passage opening to machine the workpiece.
Claims19
A use of a machine tool for machining pockets for receiving rolling elements on a workpiece in the form of a rolling bearing cage, wherein the machine tool is designed to comprise a workpiece support and a main spindle, wherein a machining tool and a clamping means are fastened to the main spindle, wherein the clamping means is designed to comprise a receiving arrangement for fastening the clamping means to the main spindle of the machine tool and a pressure plate for pressing a workpiece on a workpiece support, wherein the receiving arrangement and the pressure plate are connected via at least one pressure cylinder, wherein a contact pressure of the pressure plate on the workpiece can be adjusted in a defined manner by means of the at least one pressure cylinder, and wherein the machining tool is arranged in such a way that the machining tool can be guided through a passage opening in the pressure plate during the machining of the workpiece pressed against the workpiece support by means of the pressure plate.
A device for machining rolling element pockets in a workpiece, comprising:
- a workpiece support;
- a main spindle;
- a clamping means fastened to the main spindle, the clamping means comprising:
- a receiving arrangement for fastening the clamping means to the main spindle;
- and
- a pressure plate for pressing the workpiece on the workpiece support, the pressure plate comprising a passage opening;
- and
- a pressure cylinder connecting the receiving arrangement to the pressure plate, the pressure cylinder being arranged to provide a force to adjust a contact pressure of the pressure plate on the workpiece;
- and
- a machining tool fastened to the main spindle and guidable through the passage opening to machine the workpiece.
