Abstract
The utility model relates to an adjustable float centering ball rolling tool belonging to the rolling tools for surface finishing of holes and strengthening processing, which is characterized in that a rolling ball is arranged at the front part of a rod, and the centering ball and the regulatory part are at the back part. The utility model can not only process through holes by rolling, but also blind holes or stepped holes; rigid rolling processing can also be implemented by removing a spring.
Description
The utility model relates to a kind of workpiece cylindrical hole polishing processing and strengthens the rolling tools of processing.
Used ball rolling instrument, a kind of is the resilient balls roll extrusion, the roll extrusion ball is located by left and right support ring, be subjected to the influence of clamping precision of the accuracy of manufacture of instrument and instrument and lathe bigger, another kind is: the rigid balls rolling tools, and its centering ball is positioned at the place ahead of three roll extrusion balls, regulates the front end that bolt is positioned at the body of rod, it is too big that its shortcoming one is that leading section arrives the distance of roll extrusion ball, is not suitable for roll extrusion blind hole and shoulder hole; The 2nd, the roll extrusion ball and the body of rod and support holes contact point place are stressed bigger, influence the life-span of machining accuracy and instrument.
But but task of the present utility model provides a kind of not only roll extrusion through hole but also roll extrusion blind hole, shoulder hole; And the centering of can floating, adjustable range is big, both can be used for the elasticity rolling and processing, again can be by removing the cylindrical hole ball rolling instrument that spring carries out the rigidity rolling and processing.
Concrete measure of the present utility model is: be provided with the roll extrusion ball in the front portion of the body of rod, after the centering ball abuts against the roll extrusion ball.After conductor abutted against the centering ball, the rear portion was with guide pin bushing, and conductor is shorter than guide pin bushing, and guide pin bushing is contained in the endoporus of the body of rod, can slide relatively between conductor and the guide pin bushing and the body of rod.Be provided with adjusting screw(rod) and locking nut in the rear end of the body of rod, between conductor and guide pin bushing spring be housed.
The compared with the prior art following advantage of the utility model:
1, because the roll extrusion ball is located at the front portion, and the adjusting portion branch is located at body of rod rear end, and allowance is little between front end face and roll extrusion ball, therefore, but roll extrusion blind hole or shoulder hole owing to simple in structure, can produce the rolling tools of small-bore (below Φ 10mm).2, the roll extrusion ball is with the centering ball and contacts, and the adjustable extent of rolling quantity is big.3, three roll extrusion balls are quick condition at warp-wise, centering precision is by the accuracy guarantee of workpiece cylindrical hole, and be stable three points centering state, thus less demanding to the accuracy of manufacture and the clamping precision of the body of rod on lathe of rolling tools itself, be easy to guarantee the roll extrusion quality.
Accompanying drawing 1 is front view of the present utility model and cutaway view.
The 1-body of rod 2-roll extrusion ball 3-ball of feeling relieved
4-conductor 5-spring 6-guide pin bushing
7-locking nut 8-adjusting screw(rod)
Below in conjunction with accompanying drawing concrete structure of the present utility model and principle are described further:
Concrete structure measure of the present utility model is that roll extrusion ball 2 is located at the body of rod 1 front portion, centering ball 3 abuts against roll extrusion ball 2 back, after conductor 4 front portions abutted against centering ball 3, the rear end was inserted in the guide pin bushing 6, and guide pin bushing 6 is contained in the body of rod 1, conductor 4, guide pin bushing 6 and 1 of the body of rod can slide relatively, conductor 4 is shorter than guide pin bushing 6, spring 5 be contained in conductor 4 and and guide pin bushing 6 between, adjusting screw(rod) 8 is by the body of rod 1 rear end internal thread, withstand on guide pin bushing 6 rear ends, adjusting screw(rod) 8 is by locking nut 7 lockings.During rolling and processing, adjust rolling quantity or elasticity tension and tighten locking nut 8 and can use, adjustable unsteady centering rolling tools can be clipped on the lathe during use and rotate, workpiece is fixed; Also adjustable unsteady centering ball rolling instrument fixation workpiece can be clipped on the lathe and rotate.
In the roll extrusion process, owing to adopted three roll extrusion balls 2, utilize the bore area autobalance centering of centering ball 3 and workpiece, because roll extrusion ball 2 and the ball 3 of feeling relieved are and contact, the axial less displacement of centering ball 3 can cause roll extrusion ball warp-wise to produce bigger displacement, so adjustable range is big, when hole elasticity being added the tension force of adjusting spring 5 man-hour by adjusting screw(rod) 8, make the metal surface produce plastic deformation, when the hole rigidity is added man-hour, remove spring 5, adjust the amount of being pressed into of roll extrusion ball 2, make metal produce plastic deformation by regulating bolt.Thereby reach metal aperture polishing and rolling and processing.
