Abstract
The invention discloses an expansion core tool, which relates to the technical field of mechanical press mounting. The expansion core tool comprises an expansion core tool body and an expansion core, wherein the left end of the expansion core tool body is arranged in such a manner that one section of cylinder (1) is connected with a stepped cylinder (2) of which the diameter is larger than that of the cylinder; the right end of the stepped cylinder is connected with an inner taper hole elastic body (4); the outer diameter of the elastic body (4) is smaller than that of the stepped cylinder (2); the front end of an inner taper hole in the expansion core tool body is provided with an internal thread (3); one end of the expansion core is a columnar body (7) of which one end is provided with an external thread, and the other end of the expansion core is a cone (8) connected with the columnar body; at a working position, the columnar body (7) provided with the external thread is in threaded fit with the internal thread (3) in the expansion core tool body; and the cone (8) is in taper surface fit with the inner taper hole of the elastic body (4). According to the tool, consistent lengths, concentricity between outer circles and inner holes and verticality between end faces and outer circles of processed workpieces can be ensured.
Description
Technical field
The present invention relates to the mechanical press mounting technical field, be specifically related to a kind of core frock that rises.
Background technology
In the 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 to foreign round perpendicularity is high.
Generally be installed with scroll chuck in the prior art, but can't satisfy the aspect requirement of above-mentioned precision.
Summary of the invention
The invention technical problem to be solved provides and a kind ofly can guarantee the to foreign round high core frock that rises of perpendicularity of workpiece to be machined length direction sizing, concentricity and end face.
The invention is for solving the problems of the technologies described above, by the following technical solutions:
A kind of core frock that rises comprises 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 the internal taper hole front end is provided with internal thread in the core frock that the rises body; Described core one end that rises is for being provided with externally threaded column, and the other end is the centrum that column connects; 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 centrum 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 centrum of rising for ease of spanner.
Further, in the described core frock body that rises, span is set greater than the cavity of elastomer taper hole small end 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 to have following beneficial effect:
Because the core frock that rises of the invention is the car other end usefulness of touching the pillow behind 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, car other end control material segment length; Then take material section centre bore as the control vehicle cylindrical, thereby can guarantee to foreign round perpendicularity of the concentricity of the more consistent length of the section of expecting workpiece, cylindrical and endoporus and end face.
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 the internal taper hole front end is provided with internal thread 3 in the core frock that the rises body; Rise by core one end for being provided with externally threaded column 7, the other end is the centrum 8 that column connects.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, centrum 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 centrum of rising for ease of spanner.After column 7 and internal thread 3 screw threads screw and put in place, the male cone (strobilus masculinus) of centrum 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 can make things convenient for removal without clamping force, works and so forth.
In the core frock body that rises, 3 of elastomer 4 and internal threads arrange span greater than the cavity 5 of 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 the 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, car material section other end control material segment length; Car material section cylindrical, chamfering.
