Embodiment Construction

[0031] The present invention (utility model) will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0032] Rotary indexing machine 50 has: Figure 11 The indexing device 60 shown as a rotary drive device is arranged opposite to the indexing device 60 and is shown in figure 1 , Figure 4 , Figure 7 as well as Figure 8 The support device 70 of the workpiece, and the control device 80 of the two devices 60, 70, the control device 80 controls the support device 70 corresponding to the action of the indexing device 60. In the rotary indexer 50 , for example, for a long workpiece W, one end of the workpiece W is held by the index device 60 and the other end is held by the workpiece support device 70 .

[0033] In this embodiment, the indexing device 60 may be a device that has a working machine, specifically, a rotating shaft of a tool such as a grindstone, an end mill, a drill, a tap, or a holder for a tool such as a ...

Abstract

The invention discloses a workpiece support device, which aims at providing a workpiece support device for enhancing the processing precision of a workpiece one end of which is connected with the rotating shaft of a rotation driving device. A workpiece support device (70) includes a coupling member (3) that couples a second end of a workpiece (W); a support shaft (2), the coupling member (3) provided at a first end of the support shaft (2); a frame (1) that supports the support shaft (2) axially movably and rotatably; a force generating device (5) that applies a force in an axial direction tothe support shaft (2); and an axial clamping device (6) including a single pressing member (6a1) extending along the entire periphery of the support shaft (2) or a plurality of pressing members (6a1)equally arranged in a circumferential direction of the support shaft (2), the pressing member (6a1) generating a force in a radial direction while the force generating device (5) is activated, the axial clamping device (6) fixing the support shaft (2) to the frame (1) in the axial direction by the force.

Description

technical field [0001] The present invention relates to a support device for supporting a workpiece whose one end is connected to a rotary shaft of a rotary drive device and the other end of the workpiece. Furthermore, it is related with the rotary indexing machine provided with the support device of a workpiece, the index device as a rotation drive device provided opposite to this support device, and a control device. Background technique [0002] As the rotary drive device arranged to face the workpiece support device, there is an index device mounted on a machine tool or a spindle head of a machine tool such as a lathe. Furthermore, as an index device provided to face a workpiece support device, there are index devices mounted on machine tools, or spindle heads of machine tools such as a compound lathe having an indexing function. [0003] As a supporting device for the workpiece, there is a tailstock disposed opposite to a lathe headstock that holds one end surface of t...
