Automatic tensioning mechanism for tool shank of high-speed machining center

Abstract

The utility model discloses a kind of automatic tensioning mechanism of tool shank for high-speed machining center, it is related to lathe parts technical field, including sliding seat and locating seat, the both sides of sliding seat are rotatably connected with rotating rod one, one end of rotating rod one is rotatably connected with rotating rod two, one end of rotating rod two is rotatably connected with locating seat, the outside of locating seat is provided with tool shank lock, connecting column is fixedly connected between tool shank lock and sliding seat, connecting column and locating seat are slidably connected, the utility model is through the foldable structure design of rotating rod one, rotating rod two, when tool shank lock inner locking mechanism cannot provide axial pre-tightening force, can be through strutting and folding rotating rod two, make rotating rod one rotate and shorten total length and stretch extension spring to produce inward tension, this kind of mechanical linkage can accurately supplement axial pre-tightening force, effectively avoid the shaking in tool transmission process, significantly improve the stability when lathe machining, ensure that the precision of workpiece processing meets high standard requirement.
