Abstract
The invention provides an external grinding mandrel for thin workpieces. The external grinding mandrel is characterized in that the external grinding mandrel comprises a cylindrical mandrel body, a fixing support, a carrier, tapered cores, an open press plate and a compression nut. The fixing support, the tapered cores, the open press plate and the compression nut are sequentially arrayed on the mandrel body from left to right. The carrier is fixed on the fixing support. The external grinding mandrel has the advantages that the tapered cores are used for positioning internal holes of the workpieces, gapless matching of the external holes of the workpieces can be guaranteed even if the sizes of the external holes of the workpieces are different, and accordingly, good positioning effect is achieved; the external grinding mandrel is simple in structure, convenient to use, capable of assisting in reducing processing cost of the workpieces, and the like.
Description
Technical field
The invention belongs to machinery manufacturing technology field, especially relates to a kind of thin workpiece external grinding mandrel, for the various workpiece that need to carry out external tooth, Excircle machining are positioned.
Background technology
In the manufacturing process of workpiece, usually the external tooth of some workpiece or cylindrical are required strictly, need to carry out fine finishining to it, and require not strict to hole in workpiece.In prior art, for the orientation tool of workpiece to be processed, generally all need with hole in workpiece as positioning datum, while using such instrument, just higher to the dimensional requirement in hole in workpiece, so just increased unnecessary processing cost.
Summary of the invention
The problem that the invention will solve is to provide a kind of thin workpiece external grinding mandrel, and especially applicable 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 adopts 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 are from left to right arranged in order on described mandrel body, and described pallet is fixed on described fixed mount.
Described fixed mount is divided into two parts, first is 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 on the nearly left end of described mandrel body, and is fixedly connected with described mandrel body.
Described pallet is a bottom surface and a hollow hemicone that side surrounds, on described bottom surface, have the through hole identical with described fixed mount cylinder diameter, and be placed on 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 is connected 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 on described mandrel body middle part, and the cylindrical of described cone core is cone structure, between described cone core and described mandrel body, be provided with cone core retainer plate, between described cone core retainer plate and described fixed mount barrel portion, card has spring.
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 adopting technique scheme, by hole in cone core positioning workpieces, even inconsistent also can the assurance of hole dimension coordinates with hole gapless in workpiece in workpiece, play good positioning action, have simple in structure, easy to use, can reduce the advantages such as workpiece processing cost simultaneously.

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 are from left to right arranged in order on described mandrel body 1, and described pallet 6 is fixed on described fixed mount 5.
Described fixed mount 2 is divided into two parts, first is 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 on 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 a hollow hemicone that side surrounds, on described bottom surface, have the through hole identical with described fixed mount 2 cylinder diameters, 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 is connected 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 on 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 between described cone core retainer plate 7 and described fixed mount 2 barrel portions, card has spring 8.
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 to cone core 4 right sides, making to bore core 4 coordinates with hole in 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 clamped workpiece other end.
Above the invention embodiment is had been described in detail, but described content is only the preferred embodiment of the invention, can not be considered to for limiting the practical range of the invention.All equalization variations of doing according to the invention application range and improvement etc., within all should still belonging to the patent covering scope of the invention.
