Abstract
The invention discloses a taper sleeve expansion type inner circle positioning device. The taper sleeve expansion type inner circle positioning device comprises a mandrel, wherein a conical shaft section is formed at the front end of the mandrel; an expansion sleeve is sleeved on the conical shaft section; the contact surfaces of the conical shaft section and the expansion sleeve are matched with each other; at least three axial strip-shaped open gaps are formed on the body wall of the expansion sleeve at intervals; a compression screw is arranged in the axle center of the front end of the mandrel; the compression screw is contacted with the expansion sleeve through a ring-shaped pressing pad. The taper sleeve expansion type inner circle positioning device can eliminate the positioning gap between a tool and a workpiece and can guarantee the coaxiality of a positioning hole and a processed hole. Compression is performed by an expansion force which is uniform, so deformation of the workpiece is reduced.
Description
Technical field:
The present invention relates to a kind of replacer of tubular product, particularly relate to a kind of tapered sleeve expanding-contracting type inner circle positioner.
Background technology:
In machining, the turning processing of tubular product often can appear, and generally lean under normal circumstances cylindrical one end of jig clamping tubular product to carry out turning processing; because the effect of chucking power; the tubular product is easily deformable, easily causes deviations, affects product quality.
Summary of the invention:
Technical problem to be solved by this invention is: overcome the deficiencies in the prior art, provide a kind of simple in structure, easy to use, once be installed, accurate positioning and laborsaving timesaving tapered sleeve expanding-contracting type inner circle positioner.
Technical scheme of the present invention is: a kind of tapered sleeve expanding-contracting type inner circle positioner, contain mandrel, the front end of described mandrel is the taper shaft part, expansion sleeve of suit on this taper shaft part, the two contact surface is complementary, be arranged at intervals with axial bar shaped open seam on the body wall of described expansion sleeve, the place, front end axle center of described mandrel is provided with housing screw, and described housing screw contacts with described expansion sleeve by the annular pressure pad.
The opening direction of described axial bar shaped open seam arranges in the same way, make described expansion sleeve form the structural form that the rear end links to each other and front end separates, perhaps, the opening direction of described axial bar shaped open seam is arranged alternately, and makes described expansion sleeve form the staggered structural form separately in two ends.Described axial bar shaped open seam has three at least.The rearward end diameter of described mandrel is greater than the leading section diameter, and the rear end of described mandrel is provided with positioning round table and installing hole, and described installing hole has three at least.
The invention has the beneficial effects as follows:
1, the present invention can eliminate the positioning gap between frock and workpiece, guarantees the axiality of locating hole and institute's machining hole, utilizes expanding force to compress, because expanding force is more even, has reduced workpiece deformation.
2, be provided with axial bar shaped open seam on the body wall of expansion sleeve of the present invention, make expansion sleeve become the structural form that root links to each other and taper is diverged, more easily tensioner fixation workpiece.
3, mandrel end of the present invention and expansion sleeve inwall are taper fit, can make progressively tensioner of expansion sleeve, can adapt to the clamping of the tubular product of different inner diameters.
4, the present invention simple in structure, easy to use, once be installed, accurate positioning and laborsaving saving time, its
Applied widely, be easy to promotion and implementation, have good economic benefit.
Description of drawings:
Fig. 1 is the structural representation of tapered sleeve expanding-contracting type inner circle positioner;
Fig. 2 be among Fig. 1 A to view.
The specific embodiment:
Embodiment one: referring to Fig. 1 and Fig. 2, and among the figure, 1-mandrel, 2-expansion sleeve, 3-annular pressure pad, 4-housing screw, 5-workpiece, the axial bar shaped open seam of 6-.
Tapered sleeve expanding-contracting type inner circle positioner contains mandrel 1, wherein: the front end of mandrel 1 is the taper shaft part, expansion sleeve 2 of suit on this taper shaft part, the two contact surface is complementary, be arranged at intervals with axial bar shaped open seam 6 on the body wall of expansion sleeve 2, axially the opening direction of bar shaped open seam 6 is arranged alternately, and makes expansion sleeve 2 form the staggered structural form separately in two ends, the place, front end axle center of mandrel 1 is provided with housing screw 4, and housing screw 4 contacts with expansion sleeve 2 by annular pressure pad 3.
Axially bar shaped open seam 6 has three at least, chooses according to the diameter of expansion sleeve 2.In addition, the rearward end diameter of mandrel 1 is greater than the leading section diameter, and the rear end of mandrel 1 is provided with positioning round table and installing hole, and installing hole has three at least.
Operation principle: mandrel 1 is fixed on the lathe, again workpiece 5 is sleeved on the mandrel 1, screw housing screw 4, lean on the axial compressive force promotion expansion sleeve 2 of annular pressure pad 3 to move to left, lean on the effect of the mandrel 1 outer end conical surface to make expansion sleeve 2 spreadings, external diameter increases, thereby fit clearance and tensioner workpiece 5 that elimination and workpiece are 5, the axiality of assurance locating hole and institute's machining hole utilizes expanding force to compress, because expanding force is more even, has reduced workpiece deformation.
Embodiment two: the present embodiment and embodiment one are basic identical, and something in common does not repeat, and difference is: axially the opening direction of bar shaped open seam arranges in the same way, makes expansion sleeve form the structural form that the rear end links to each other and front end separates.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
