A from centering clamping device for casing and flange laser welding

The utility model relates to a from centering clamping device for casing and flange laser welding, install reduction gear and servo motor on motion platform's bottom plate, servo motor's output shaft passes through the shaft coupling and is connected with the input shaft drive of reduction gear, install the casing on the output shaft of reduction gear, install the fluted disc on the casing, the fluted disc is connected by motor drive, the meshing has three group's toothholders on the fluted disc, contained angle between the adjacent toothholder equals, the radial motion is followed to fluted disc drive toothholder, the top of toothholder is equipped with the convex clamping part that is used for the tight casing of locating clip, along radially installing the electric putter ware on each toothholder, the top of the work stock of electric putter ware is equipped with the clamp part that is used for the tight flange of locating clip. Can drive the work piece plane and remove and the rotation, the laser head holding position is unchangeable during the welding, improves welded stability, and to the such thin wall part of flange, the real -time measurement of clamp force can be controlled the clamp force effectively and avoid too big and arouse clamping deformation under the prerequisite that meets the demands.
