Abstract

The invention provides a workpiece support device and a machine tool. The workpiece support device comprises a rotating table and a C-axis driving part. The C-axis driving part is used for driving the rotating table to rotate. A holding mechanism is installed on the upper surface of the rotating table. The C-axis driving part comprises a C-axis motor and an encoder. The upper end part of a rotating shaft of the C-axis motor is connected with the rotating table. A rotating cylinder used for driving the holding mechanism is fixed on an installation part of a shaft cover arranged on the lower end part of the rotating shaft. A detection element of the encoder is fixed on the inner side of a main body part. A detected body of the encoder is fixed on an encoder rotator rotating with the rotating shaft. The encoder rotator is installed on the rotating shaft. In this way, the vibration generated in the rotating process of the rotating shaft of the rotating cylinder are not liable to influence the detected body of the encoder.

Description

technical field [0001] The present invention relates to a workpiece supporting device and a machine tool. Background technique [0002] The machine tool disclosed in Japanese Patent Laid-Open No. 188800 of 2013 is capable of selectively performing rotary processing and turning processing on a workpiece. The machine tool has two spindles on which a workpiece is mounted and a tool is mounted on the other, and either is rotated relative to the other. The spindle for mounting the workpiece includes a rotary table. The drive unit for driving the turntable includes a housing, a motor, an encoder, and the like. The rotation shaft of the motor is connected to the turntable. An encoder includes an object to be detected and a detection element. The object to be detected is attached to an encoder rotating body (substrate) fixed to the shaft end of the rotating shaft, and the detection element is fixed inside the case. The encoder detects the rotation angle of the rotary shaft by d...
