The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a floating chamfering tool of OBC casing foundry goods deburring, includes centre gripping handle and handle of a knife, the inside inner chamber that is equipped with the tube-shape of centre gripping handle, this inner chamber upper end is opened and is sealed through the stopper, the inner chamber in slidable mounting have a float lever, the vertical terminal surface under the centre gripping handle that runs through of this float lever lower extreme, float lever lower extreme threaded connection have a lock sleeve, install in this lock sleeve and rise tight cover, handle of a knife one end insert in the tight cover that rises, this handle of a knife other end is provided with the chamfer tool bit, the inside spring of installing between float lever and the stopper that is located of inner chamber.

As right technical scheme a supplement, the stopper choose for use countersunk head hexagon socket head cap screw, this countersunk head hexagon socket head cap screw and inner chamber upper end mouth inner wall threaded connection.

As right technical scheme a supplement, the floating lever lower extreme be the screw thread post, a recess has been seted up at the middle part of this screw thread post bottom surface, the tight cover that rises install at the recess, the screw thread post on have connect the lock sleeve.

As right technical scheme a supplement, the floating rod upper end arranged round step portion, the inner chamber bottom vertically seted up a circular through-hole, the diameter of this circular through-hole is less than the diameter of step portion, the diameter of circular through-hole be greater than the diameter of floating rod.

Has the advantages that: the utility model relates to a processing burr's unsteady chamfer cutter is got rid of to OBC casing foundry goods, the lock sleeve is screwed to the float lever lower extreme, the inside tight cover that rises of lock sleeve rises with the handle of a knife rises tightly, it is fixed to realize the handle of a knife, rise tight cover through rotatory lock sleeve control and rise tightly or loosen, whole operation is comparatively convenient, the float lever can slide from top to bottom along the inner chamber of centre gripping handle, realize the unsteady design of chamfer tool bit, chamfer tool bit elastic contact is by the processing edge, when guaranteeing to get rid of the processing burr, guarantee the uniformity of edge chamfer.
