Abstract

The utility model provides a thin workpiece external grinding mandrel which is characterized by comprising a cylindrical mandrel body, a fixing frame, a support disc, a cone core, an open pressing plate and a pressing nut. The fixing frame, the cone core, the open pressing plate and the pressing nut are arrayed on the mandrel body in sequence from left to right. The support disc is fixed on the fixing frame. The thin workpiece external grinding mandrel has the advantages that a workpiece inner hole is located through the cone core, even if the sizes of workpiece inner holes are not the same, the fact that the cone core and the workpiece inner hole are matched without a gap can be guaranteed, good locating effect is achieved, structure is simple, using is convenient, and meanwhile machining cost of a workpiece can be lowered and the like.

Description

Thin workpiece external grinding mandrel
Technical field
The invention belongs to machinery manufacturing technology field, especially relates to a kind of thin workpiece external grinding mandrel, positions for the workpiece that various needs is carried out external tooth, Excircle machining.
Background technology
In the manufacturing process of workpiece, usually strict to external tooth or the cylindrical of some workpiece, need to carry out fine finishining to it, and require not strict to hole in the workpiece.The orientation tool that is used for workpiece to be processed in the prior art generally all needs with hole in the workpiece as positioning datum, and is just higher to the dimensional requirement in hole in the workpiece when using such instrument, so just increased unnecessary processing cost.
Summary of the invention
The problem that the invention will solve provides a kind of thin workpiece external grinding mandrel, and especially suitable thinner to size, inner hole dimension requires undemanding workpiece to position.
For solving the problems of the technologies described above, the technical scheme that the invention is adopted is: a kind of thin workpiece external grinding mandrel, it is characterized in that: comprise cylindric mandrel body, fixed mount, pallet, cone core, opening pressing plate and clamp nut, described fixed mount, cone core, opening pressing plate and clamp nut from left to right are arranged in order on described mandrel body, and described pallet is fixed on the described fixed mount.
Described fixed mount is divided into two parts, first is the semicircle cone, second portion is cylinder, the bottom surface of described semicircle cone and described cylindrical bottom surface adjacency, described first and second portion are one-body molded, and the inside of described fixed mount has through hole, and the diameter of described through hole is identical with the diameter of described mandrel body, described fixed mount is placed in the nearly left end of described mandrel body, and is fixedly connected with described mandrel body.
Described pallet is a bottom surface and the hollow hemicone that the side surrounds, have the through hole identical with described fixed mount cylinder diameter on the described bottom surface, and be placed on the described fixed mount barrel portion, the bottom surface of described fixed mount semicircle conical section is withstood in the bottom surface of described pallet, and links to each other with described fixed mount by bolt.
Described cone core is discoid, inside has the through hole identical with described mandrel body diameter, and is placed in described mandrel body middle part, and the cylindrical of described cone core is cone structure, be provided with the cone core retainer plate between described cone core and described mandrel body, card has spring between described cone core retainer plate and described fixed mount barrel portion.
Described clamp nut is positioned at the right-hand member of described mandrel body, and with described mandrel body threaded engagement.
Described opening pressing plate inserts in the right part of described mandrel body, between described clamp nut and described cone core.
Advantage and good effect that the invention has are: owing to adopt technique scheme, by hole in the cone core positioning workpieces, even inconsistent also can the assurance of hole dimension cooperates with hole gapless in the workpiece in the workpiece, play preferably positioning action, have simple in structure, easy to use, can reduce the advantages such as workpiece processing cost simultaneously.
Description of drawings
Fig. 1 is the structural representation of the invention
Among the figure:
The specific embodiment
As shown in Figure 1, the invention comprises cylindric mandrel body 1, fixed mount 2, pallet 3, cone core 4, opening pressing plate 5 and clamp nut 6, described fixed mount 2, cone core 4, opening pressing plate 5 and clamp nut 6 from left to right are arranged in order on described mandrel body 1, and described pallet 6 is fixed on the described fixed mount 5.
Described fixed mount 2 is divided into two parts, first is the semicircle cone, second portion is cylinder, the bottom surface of described semicircle cone and described cylindrical bottom surface adjacency, described first and second portion are one-body molded, and the inside of described fixed mount 2 has through hole, and the diameter of described through hole is identical with the diameter of described mandrel body 1, described fixed mount 2 is placed in the nearly left end of described mandrel body 1, and is fixedly connected with described mandrel body 1.
Described pallet 3 is a bottom surface and the hollow hemicone that the side surrounds, have the through hole identical with described fixed mount 2 cylinder diameters on the described bottom surface, and be placed on described fixed mount 2 barrel portions, the bottom surface of described fixed mount 2 semicircle conical sections is withstood in the bottom surface of described pallet 3, and links to each other with described fixed mount 2 by bolt.
Described cone core 4 is discoid, inside has the through hole identical with described mandrel body 1 diameter, and be placed in described mandrel body 1 middle part, the cylindrical of described cone core 4 is cone structure, described cone core 4 and 1 of described mandrel body are provided with cone core retainer plate 7, and card has spring 8 between described cone core retainer plate 7 and described fixed mount 2 barrel portions.
Described clamp nut 6 is positioned at the right-hand member of described mandrel body 1, and with described mandrel body 1 threaded engagement.
Described opening pressing plate 5 inserts in the right part of described mandrel body 1, between described clamp nut 6 and described cone core 4.
The course of work of this example: workpiece to be processed is placed on cone core 4 right sides, cone core 4 is cooperated with hole in the workpiece, workpiece is promoted left, because cone core 4 cylindricals are cone structure, it can slide to pallet 3 directions under the effect of workpiece and spring 8, until the end face of workpiece pushes up pallet 3, then put opening pressing plate 5, rotatably compress nut 6 opening pressing plate 5 is got final product the clamping of workpiece other end.
More than the embodiment of the invention is had been described in detail, but described content only is the preferred embodiment of the invention, can not be considered to for the practical range that limits the invention.All equalizations of doing according to the invention application range change and improve etc., all should still belong within the patent covering scope of the invention.
