Claims

[Claims for Utility Model Registration] (1) A work rest device for a turning machine tool that performs turning processing by supporting a workpiece between a spindle side center and a tail stock side center, which a base provided between the base body, a rotating shaft rotatably supported by the base body, a driving body provided on the base body for rotating the rotating shaft, and a driving force of the driving body that rotates the rotating shaft. A transmission member for transmitting information to the shaft, and a support portion having one end fixed to the rotation shaft and the other end supporting a workpiece, the support portion being swingable at a predetermined angle about the rotation shaft as a fulcrum, and positioning the support portion in a fixed position. and a pressure adjusting means that adjusts the supply pressure of the drive body in order to maintain the position of the support part in accordance with the weight of the workpiece received by the support part, and the workpiece is placed on the support part. A work rest device having a balancer function, which supports a work in a balanced manner so that the work is maintained at a position near the spindle axis when the work is rotated. (2) A utility model in which a detection means for detecting the supply pressure to the driving body is provided in the circuit configuration to set the supply pressure to a predetermined pressure when the workpiece is placed on the support part of the swing arm. A work rest device having a balance function as claimed in claim 1. (3) A work rest having a balance function as set forth in claim 1 of the utility model registration claim, in which the supporting part of the swinging arm is a support member having a shape corresponding to the shape of the workpiece and can be detachably attached to the swinging arm. Device.
