Abstract
The utility model relates to an inner expansion type positioning clamp and aims at providing a positioning clamp which not only can ensure that a mandrel clamps workpieces under the condition of deformation as less as possible, but also can ensure that the workpieces are conveniently and quickly assembled and disassembled. The technical scheme for achieving the aim of the utility model is that the inner expansion type positioning clamp consists of the mandrel and a positioning surface arranged on the mandrel; one end of the mandrel is conical and is matched with a main shaft hole connected with a machine tool; an axial inner conical hole is arranged at the other end of the mandrel; a plurality of through grooves are equally arranged on the wall of the inner conical hole; and an inner cone consistent with the taper of the inner conical hole is arranged in the inner conical hole.
Description
Technical field
The utility model relates to field of machining, particularly the anchor clamps of processing thin-walled part.
Background technology
When the thin-walled parts that the axiality of processing excircles and endoporus is had relatively high expectations, general technology is: the folder cylindrical, face work and endoporus are then with anti-three-jaw support endoporus, processing excircles and groove.But in the practical operation because the axiality of anti-three-jaw and machine tool chief axis axis can not strict guarantee, and because workpiece wall is thin, support endoporus after, yielding, cause the axiality of the cylindrical of workpiece and endoporus overproof.Therefore, need a kind of axle anchor clamps, the centering precision height, simple in structure, cost is low.
Summary of the invention
The purpose of this utility model is to provide a kind of internal-expansion type positioning fixture, and these anchor clamps both can make axle clamping work pieces under the as far as possible little situation of distortion, can make workpiece loading and unloading convenient, fast again.
Realize that the utility model purpose technical scheme is: a kind of internal-expansion type positioning fixture, form by axle and the locating surface that is arranged on the axle, it is conical that one end of axle is, the spindle hole of lathe adapts with connection, the described axle other end is provided with an axial internal taper hole, and the inner cone hole wall by etc. be arranged with some grooves, in described internal taper hole, be provided with the inner cone consistent with the internal taper hole tapering.
Described inner cone hole wall is opened groove by 6 five equilibriums or 4 five equilibriums, groove width 1.5～2.0mm.
The described axle other end is because of being provided with groove, and becomes elastic tip.For with the complete distending of internal taper hole, the length of described inner cone is greater than internal taper hole.
During use, earlier inner cone is screwed out, workpiece is contained on the axle other end, the end face of workpiece and the locating surface on the axle are adjacent to, unlikely crooked, screw in inner cone again, at this moment the elastic tip of anchor clamps is because the screw-in of inner cone and dilating gradually, with the workpiece swelling on axle; After completion of processing, the counter-rotating inner cone restores to the original state the elastic tip of axle, can take off workpiece like a cork.
The external diameter of workpiece endoporus of the present utility model and axle adopts matched in clearance, so both can make elastic tip clamping work pieces under the as far as possible little situation of distortion of axle, can make workpiece loading and unloading convenient, fast again.The utility model centering precision height, simple in structure, cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation that groove is set on the internal taper hole of utility model embodiment 1.
The specific embodiment
Be described further below in conjunction with drawings and Examples.
Embodiment 1
As shown in Figure 1, a kind of internal-expansion type positioning fixture 10, form by axle 1 and the locating surface 2 that is arranged on the axle, it is conical that one end 3 of axle is, the spindle hole of lathe adapts with connection, the axle other end 5 is provided with an axial internal taper hole 8, is arranged with four grooves 4, groove width 1.5～2.0mm at the inner cone hole wall by waiting.As shown in Figure 2.In internal taper hole 8, be provided with the inner cone consistent 6 with the internal taper hole tapering.
During use, earlier inner cone 6 is screwed out, workpiece 7 is contained on the axle other end, the end face and the locating surface on the axle 2 of workpiece 7 are adjacent to, unlikely crooked, screw in inner cone 6 again, at this moment since the axle other end 5 because the screw-in of inner cone 6 and dilating gradually, with workpiece 7 swellings on axle 1; After completion of processing, counter-rotating inner cone 6 restores to the original state the other end 5 of axle, can take off workpiece 7 like a cork.
Claims (3)
1. internal-expansion type positioning fixture, form by axle and the locating surface that is arranged on the axle, it is conical that one end of axle is, the spindle hole of lathe adapts with connection, it is characterized in that, the described axle other end is provided with an axial internal taper hole, and the inner cone hole wall by etc. be arranged with some grooves, in described internal taper hole, be provided with the inner cone consistent with the internal taper hole tapering.
2. internal-expansion type positioning fixture according to claim 1 is characterized in that, described inner cone hole wall is opened groove by 6 five equilibriums or 4 five equilibriums, groove width 1.5～2.0mm.
