Workpiece Supporting Device Of A Circular Sawing Machine

摘要

A workpiece supporting device of a circular sawing machine includes a base frame for rotatably supporting a worktable and having an arcuate surface region which defines an angularly extending guiding route. A platform is disposed on and is movable along the guiding route, and has an upper mounting surface that cooperates with the worktable to support a workpiece. A tightening mechanism is displaceable between unmovable and movable positions, where the platform is brought into tight and loose engagements with the arcuate surface region. An actuator is coupled with the tightening mechanism is operable to displace the tightening mechanism. The platform is movable along the guiding route when the tightening mechanism is in the movable position such that the worktable is turnable within a relatively large angular range.
