Abstract
The utility model discloses an inner circle tensioning type mandrel fixture which comprises a mandrel, wherein the front end of the mandrel is a conical shaft section; a tensioning sleeve is sleeved on the conical shaft section, and contact surfaces of the tensioning sleeve and the conical shaft section are matched; axial strip open slits are spaced on the body wall of the tensioning sleeve; a compression screw is arranged at the axial centre of the front end of the mandrel; the compression screw is in contact with the tensioning sleeve through an annular pressure pad; and at least three axial strip open slits are formed. The inner circle tensioning type mandrel fixture disclosed by the utility model can eliminate a positioning gap between a tool and a workpiece and guarantee the coaxiality between a positioning hole and a processing hole; compression is realized by use of tensioning force; and since the tensioning force is relatively uniform, the workpiece deformation is reduced.
Description
Technical field:
The utility model relates to a kind of replacer of tubular product, particularly relates to a kind of inner circle swelled dabber clamp.
Background technology:
In machining, often there will be the turning processing of tubular product, generally lean under normal circumstances cylindrical one end of jig clamping tubular product to carry out turning processing; effect due to chucking power; the tubular product is easily deformable, easily causes deviations, affects product quality.
The utility model content:
Technical problem to be solved in the utility model 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 inner circle swelled dabber clamp.
The technical solution of the utility model is: a kind of inner circle swelled dabber clamp, 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, on the body wall of described expansion sleeve, be arranged at intervals with axial bar shaped open seam, 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 rear end is connected 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 beneficial effects of the utility model are:
1, the utility model can be eliminated the positioning gap between frock and workpiece, guarantees the axiality of locating hole and institute's machining hole, utilizes expanding force to compress, and because expanding force is more even, has reduced workpiece deformation.
2, on the body wall of the utility model expansion sleeve, be provided with axial bar shaped open seam, make expansion sleeve become the structural form that root is connected and taper is diverged, tensioner fixation workpiece more easily.
3, the utility model mandrel end 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 utility model 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.
The accompanying drawing explanation:
Fig. 1 is the structural representation of inner circle swelled dabber clamp;
Fig. 2 be in Fig. 1 A to view.
The specific embodiment:
Embodiment mono-: referring to Fig. 1 and Fig. 2, and in figure, 1-mandrel, 2-expansion sleeve, 3-annular pressure pad, 4-housing screw, 5-workpiece, the axial bar shaped open seam of 6-.
Inner circle swelled dabber clamp 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, on the body wall of expansion sleeve 2, be arranged at intervals with axial bar shaped open seam 6, 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 lathe, again workpiece 5 is sleeved on 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 tensioner workpiece 5 that elimination and workpiece are 5, the axiality of assurance locating hole and institute's machining hole, utilize expanding force to compress, because expanding force is more even, reduced workpiece deformation.
Embodiment bis-: the present embodiment and embodiment mono-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 rear end is connected and front end separates.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, every foundation technical spirit of the present utility model, to any simple modification, equivalent variations and modification that above embodiment does, all still belongs in the scope of technical solutions of the utility model.
