Abstract
The utility model discloses a rising core tool, and relates to the technical field of mechanical pressing. The rising core tool comprises a rising core tool body and a rising core, a section of cylindrical body (1) is arranged at the left end of the rising core tool body and is connected with a step cylinder (2) with the diameter being larger than the diameter of the cylindrical body, and the right end of the step cylinder is connected with an inner taper hole elastic body (4). The outer diameter of the elastic body (4) is smaller than the outer diameter of the step cylinder (2), and internal threads (3) are arranged at the front end of an inner taper hole inside the rising core tool body. One end of the rising core is provided with a cylinder body (7) with external threads, and the other end of the rising core is provided with a cone body (8). In a work station, the cylinder body (7) with the external threads is in thread fit with the internal threads (3) inside the rising core tool body, and the cone body (8) and the inner taper hole of the elastic body (4) are in taper face fit. The rising core tool can guarantee processed workpieces to be uniform in length, in concentricity of outer circles and the inner holes and in perpendicularity of end faces to the outer circles.
Description
Technical field
The utility model relates to the mechanical press mounting technical field, is specifically related to a kind of core frock that rises.
Background technology
In machining process, can run into workpiece is worked into certain measured length, and need turning, require the concentricity of cylindrical and workpiece center hole high, end face perpendicularity to foreign round is high.
Generally with scroll chuck, be installed in prior art, but can't meet the aspect requirement of above-mentioned precision.
Summary of the invention
The invention technical problem to be solved is to provide and a kind ofly can guarantees workpiece to be machined length direction sizing, concentricity and the end face high core frock that rises of perpendicularity to foreign round.
The invention is for solving the problems of the technologies described above, by the following technical solutions:
A kind of core frock that rises, comprise rise core frock body and the core that rises, and the described core frock body left end that rises is set to one section cylinder connection one diameter greater than cylindrical step cylinder, and step cylinder right-hand member connects the internal taper hole elastomer; The elastomer external diameter is less than step cylinder external diameter, and in the core frock that rises body, the internal taper hole front end is provided with internal thread; Described core one end that rises is for being provided with externally threaded column, and the other end is cone; During working position, described externally threaded column and the interior internal thread formation of the core frock body that the rises threaded engagement of being provided with, described cone and elastomer internal taper hole form cone match.
Further, can tighten rise core and the core frock body that rises, the large end grooved faces of the core cone that rises for ease of spanner.
Further, in the described core frock body that rises, the cavity of span greater than elastomer taper hole small end is set between elastomer and internal thread, arranging of cavity one is that be convenient to the to rise column turnover of core screws with internal thread, the 2nd, discharge the core frock body Machining stress that rises, the 3rd, increase elastomer radial expansion ability.
Further, step cylinder right-hand member arranges one section transition cylinder so that clamping workpiece.
Further, elastomer and step cylinder connection place arrange the stress groove.
Owing to having adopted technique scheme, the invention has following beneficial effect:
Because the core frock that rises of the invention is the car other end use of touching the pillow after car material section one end face, the core frock that rises be close to the material section car see the light end face, the support material section that a rises centre bore, the material segment length is controlled in the car other end; Then take material section centre bore as the control vehicle cylindrical, thereby can guarantee the concentricity of the more consistent length of the section of expecting workpiece, cylindrical and endoporus and end face perpendicularity to foreign round.
Description of drawings
Fig. 1 is the structural representation of core frock duty of rising;
The specific embodiment
In conjunction with Fig. 1, the core frock that rises comprises rise core frock body and the core that rises, and wherein, the core frock that rises body left end is set to one section cylinder 1 and connects a diameter greater than cylindrical step cylinder 2, and such structure is so that the clamping folder leans on; Step cylinder right-hand member connects internal taper hole elastomer 4, and step cylinder right-hand member can connect one section path transition cylinder so that clamping workpiece; When the path cylinder of transition was not set, workpiece directly leaned against step cylinder right-hand member.Elastomer 4 external diameters are less than step cylinder 2 external diameters, and in the core frock that rises body, the internal taper hole front end is provided with internal thread 3; Rise by core one end for being provided with externally threaded column 7, the other end is cone 8.During working position, be provided with externally threaded column 7 and form threaded engagement with the interior internal thread 3 of the core frock body that rises, strain rise core frock body and the core that rises, cone 8 and elastomer 4 internal taper holes formation cone match.Wherein, can tighten rise core and the core frock body that rises, the large end grooved faces 9 of the core cone that rises for ease of spanner.After column 7 and internal thread 3 screw threads screw and put in place, the male cone (strobilus masculinus) of cone 8 struts elastomer 4, strength stretching material section 10 central through holes that lean on elastomer 4 radially to strut, unclamping the screw thread rear cone throws off, elastomer 4 radial contraction, workpiece material section 10, without clamping force, can facilitate removal, works and so forth.
In the core frock body that rises, 3 of elastomer 4 and internal threads arrange the cavity 5 of span greater than elastomer 4 taper hole small ends.The transition circle cylinder place that elastomer 4 is connected with step cylinder 2 right-hand members arranges stress groove 6, one, discharges the core frock body Machining stress that rises, and the 2nd, be convenient to workpiece material section 10 and be close to the core frock body that rises.
When the core frock that rises is applied in machined, at first machined material section Che Yiduan end face is seen light, after drilling through centre bore, central through hole material section upset 180 is touched the pillow, the employing core frock that rises is close to car and sees the light end face, screw rise core and the core frock stretching material section through hole that rises, the material segment length is controlled in car material section other end; Car material section cylindrical, chamfering.
