Abstract
The invention relates to a central spindle which is used on various flexible shafts and used with an outer tube of the flexible shaft. The outer tube of the flexible shaft comprises a coating layer, a straight silk tube and a lining tube, wherein the coating layer is positioned on the outer surface of the straight silk tube; the straight silk tube is positioned on the outer surface of the lining tube; wherein the central spindle is positioned inside the outer tube of the flexible shaft; the central spindle comprises a central steel wire, an outer layer silk and a polygon prism; the central steel wire is positioned in the centermost of the central spindle; the outer layer silk is twiddled outside the central steel wire; the polygon prism is molded outside the outer layer silk; and the ridge of the polygon prism is connected with the inner surface of the lining tube in a propping manner. By means of the central spindle, the contact between wires and faces is realized, the contact area is reduced, the friction force is lowered, and the idle stroke is low.
Description
Technical field
The present invention relates to mandrel field, particularly relate to a kind of mandrel used on various flexible axle.
Background technique
Current, the mandrel that flexible axle uses is varied, is after all to be formed by some tiny steel wire twisteds, but, these mandrels with flexible axle outer tube with the use of in process, frictional force between the two and idle stroke are all larger, and this brings very large inconvenience to user.In addition, when flexible axle dish is good, the mandrel of its inside is difficult to motion.
Because above-mentioned existing mandrel Problems existing, the present inventor is based on being engaged in the practical experience and professional knowledge that this type of product specification manufacture enriches for many years, and coordinate the utilization of scientific principle, actively in addition research and innovation, to founding a kind of mandrel of new structure, existing Problems existing can be solved, make it have more practicability.Through constantly research, design, and through repeatedly studying sample and after improving, finally creating the present invention had practical value.
Summary of the invention
The object of the invention is providing a kind of mandrel, the contact in line and face can be realized, reduce area of contact, reduce friction, and idle stroke is less.
The object of the invention is to adopt following technological scheme to realize.The invention provides a kind of mandrel, use on various flexible axle, and with flexible axle outer tube with the use of, this flexible axle outer tube comprises coating layer, raw silk rings pipe and internal lining pipe, and this coating layer is positioned on the outer surface of raw silk rings pipe, and this raw silk rings pipe is positioned on the outer surface of internal lining pipe; Wherein this mandrel is positioned at the inside of flexible axle outer tube, this mandrel comprises core wire, outer silk and class polygon prism, this core wire is positioned at the bosom of mandrel, this outer silk is twisted with the fingers in the outside of core wire, such polygon prism is injection-moulded in the outside of outer silk, and the rib of such polygon prism abuts with the internal surface of internal lining pipe.
Object of the present invention can also be further achieved by the following technical measures.
Aforesaid mandrel, wherein such polygon prism is cylindrical outer surface upper process many triangular prisms, and triangular prism abuts with the internal surface of internal lining pipe.
Aforesaid mandrel, wherein such polygon prism is class ten prism.
The present invention compared with prior art has obvious advantage and beneficial effect.By technique scheme, the present invention has following advantages and beneficial effect:
By the present invention, the triangular prism outside such polygon prism abuts with the internal surface of internal lining pipe, to realize the contact of line and face, reduces area of contact, reduces friction.In addition, because the gap of mandrel of the present invention and flexible axle outer tube wall is smaller, the idle stroke produced when reducing mandrel motion, and when flexible axle dish well uses afterwards, mandrel is still movable.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to technological means of the present invention can be better understood, and can be implemented according to the content of specification, and can become apparent to allow above and other object of the present invention, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Accompanying drawing explanation
Fig. 1: for mandrel of the present invention and flexible axle outer tube are with the use of figure.
Fig. 2: be the structural representation of mandrel of the present invention.
[primary component symbol description]
1: coating layer 2: raw silk rings pipe
3: internal lining pipe 4: core wire
5: outer silk 6: class polygon prism
Embodiment
For further setting forth the present invention for the technological means reaching predetermined goal of the invention and take and effect, below in conjunction with accompanying drawing and preferred embodiment, to its embodiment of a kind of mandrel proposed according to the present invention, structure, feature and effect thereof, be described in detail as follows.
Consult shown in Fig. 1 and Fig. 2, Fig. 1 is mandrel of the present invention and flexible axle outer tube is the structural representation of mandrel of the present invention with the use of figure, Fig. 2.Wherein, above-mentioned mandrel uses on various flexible axle, and with flexible axle outer tube with the use of, this mandrel is positioned at the inside of flexible axle outer tube.
Concrete, this flexible axle outer tube comprises coating layer 1, raw silk rings pipe 2 and internal lining pipe 3, and this coating layer 1 is positioned on the outer surface of raw silk rings pipe 2, and this raw silk rings pipe 2 is positioned on the outer surface of internal lining pipe 3, namely coating layer 1, raw silk rings pipe 2 and internal lining pipe 3 is folded be located at together with.This mandrel comprises core wire 4, outer silk 5 and class polygon prism 6, this core wire 4 is positioned at the bosom of mandrel, mainly play the effect of push-and-pull, this outer silk 5 is twisted with the fingers in the outside of core wire 4, to protect core wire further, reduce wear, and increase integral diameter, increase push-pull effort, make mandrel more firm, durable in use; Such polygon prism 6 is injection moulding class polygon prisms, and such polygon prism 6 is injection-moulded in the outside of outer silk 5, and the rib of such polygon prism abuts with the internal surface of internal lining pipe.It should be noted that, such polygon prism 6 is cylindrical outer surface upper process many triangular prisms, but the present invention does not limit the quantity of triangular prism on cylindrical outer surface, can determine, satisfy the demands with the size of external diameter.Such as, such polygon prism 6 is chosen as class ten prism, i.e. cylindrical outer surface upper process 10 triangular prisms.In addition, the form of such polygon prism 6 inside can have a lot, is not limited to one, and such as, the inside of such polygon prism 6 is by the finer wire twisted structure together of some.
In actual applications, the triangular prism outside such polygon prism 6 abuts with the internal surface of internal lining pipe 3, to realize the contact of line and face, reduces area of contact, reduces friction.In addition, because the gap of mandrel of the present invention and flexible axle outer tube wall is smaller, the idle stroke produced when reducing mandrel motion, and when flexible axle dish well uses afterwards, mandrel is still movable.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solution of the present invention, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
