A clamping tool with bidirectional clamping and synchronous rotation functions

Abstract

The utility model relates to a kind of clamping tool with the function of two-way clamping and synchronous rotation, including tool base and its above two groups of sliding platform and rotary needle, linear guide rail is equipped on tool base, sliding platform is slidably arranged on linear guide rail, one end of linear guide rail is connected with sliding platform driving motor, positive and negative toothed rod is equipped in tool base, sliding platform is screwed on positive and negative toothed rod by threaded block, its below parallelly is equipped with guide slide bar, one end of guide slide bar is connected with synchronous rotation driving motor, guide slide bar both ends are slidably sleeved with guide block, two guide blocks can be synchronously rotated with guide slide bar, guide block is rotatably connected with two sliding platforms by connecting plate, the outer end of two guide blocks is equipped with driving wheel, two rotary needle tail ends are equipped with synchronous passive wheel in cooperation. The tool two rotary needles have the function of spherical workpiece opposite clamping and synchronous rotation, and the symmetry of spherical workpiece machining can be improved.
