Summary of the invention
The utility model is not enough for prior art, there is provided a kind of three lobe wedge-type quick centralizer, adopt three lobe key-like structure, have centering precision high, clamping, pine folder are quick and convenient, do not hinder locating surface and the advantages such as reusable clamping, be conducive to the working time shortening lathe Set and Positioning, ensure workpiece quality and precision, cost-saving, enhance productivity.
The technical solution adopted in the utility model is:
The quick centralizer of a kind of three lobe wedge-type, there is centering wedge axle, one end face of centering wedge axle is provided with adjustment screw, the other end is arranged to the descending axis of cone of external diameter, the outer wall of the axis of cone is provided with three voussoirs coordinated with the axis of cone, and the outer wall of three voussoirs is provided with elastic collar, makes three voussoirs be fixed on the outer wall of the axis of cone, three voussoirs have extension relative to the axis of cone, and the inwall of extension is provided with groove; The inside of centering wedge axle is provided with the mandrel coaxial with centering wedge axle, and one end of mandrel is connected with adjustment screw by spring, and the other end extends to the outside of centering wedge axle and is provided with the flange with groove effect.
The described quick centralizer of three lobe wedge-types, described mandrel is provided with long recess, and the centering wedge axle corresponding with long recess is provided with tapped through hole, and bolt acts on long recess by tapped through hole.
The described quick centralizer of three lobe wedge-types, the middle part of described centering wedge axle is provided with thick shaft part, and the external diameter of thick shaft part is greater than the maximum outside diameter of the axis of cone, has step surface between thick shaft part and the axis of cone.
The described quick centralizer of three lobe wedge-types, the outer wall of described three voussoirs is provided with annular groove, and described elastic collar is placed in annular groove.
The described quick centralizer of three lobe wedge-types, the center of described mandrel other end is provided with top shrinkage pool.
The described quick centralizer of three lobe wedge-types, also comprises the tail centre coordinated with top shrinkage pool.
The utility model has following beneficial effect:
The structure that the utility model adopts centering wedge axle to coordinate with three voussoirs, the arc outer wall acting in conjunction of three voussoirs in Workpiece fixing hole inwall, and is worked in coordination, by the locating hole tensioner of workpiece, there is centering precision high, do not hinder locating surface and reusable advantage.Elastic collar effectively encases three voussoirs, prevents voussoir and centering wedge axle from throwing off.One end that promotion mandrel has flange is moved in centering wedge axle, and spring-compressed, mandrel drives three voussoirs to move to the big outer diameter section of the axis of cone by flange with coordinating of groove, tensioner locating hole.Cancel the thrust to mandrel, mandrel under the action of the spring automatic traction three voussoirs resets.The whole course of work is all resilient engagement, therefore can ensure the quality in Workpiece fixing hole, not hinder locating surface.
By arranging long recess on mandrel, centering wedge axle arranging tapped through hole, making bolt can limit mandrel relative to the displacement of centering wedge axle by tapped through hole and long recess, preventing mandrel from producing inertia under the action of the spring and caused motion.Annular groove is set at the outer wall of three voussoirs, elastic collar is placed in annular groove, the outer wall of three voussoirs can effectively be coordinated with Workpiece fixing hole inwall.Mandrel arranges top shrinkage pool, tail centre is set and acts on the motion of top shrinkage pool promotion mandrel, the centering clamping work of this fixture can be completed fast.This clamp structure is simple, is conducive to shortening the lathe Set and Positioning time, ensures workpiece quality and precision, cost-saving, enhances productivity, and is suitable for batch production.
