Abstract
The utility model discloses a novel cut integrative hobbing cutter structure that a ware was used, including the hobbing cutter body, the both ends of hobbing cutter body all be provided with integrated into one piece's axle spare, the hobbing cutter body be solid construction. Low production cost, small volume and long service life.
Description
Technical Field
The utility model belongs to the technical field of the stationery that a pencil cut and specifically relates to a novel integrative hobbing cutter structure that cuts an utensil is related to.
Background
The existing common pencil sharpener has two categories, the first category is a single-edge pencil sharpener, a thin blade is directly fastened on a tool rest by a bolt or a screw, and flaky pencil scraps are planed by rotating a pencil, so that the pencil sharpener is simple in structure, but the blade is easy to blunt, short in service life, easy to break a pencil point and quick in cutting quality reduction; the second type is a spiral hob pencil sharpener, namely, a hob arranged on a hob holder rotates around a shaft to cut a pencil fixed at the center of the hob holder and dig out filament-shaped pencil scraps, so that the pencil sharpener is easy to cut and has long service life.
The existing hob structure is as shown in fig. 1: a through hole 03 for tightly matching the gear 05 and the shaft sleeve 04 is machined in the center of the hob body 01, the shaft sleeve 04 and the gear 05 are tightly connected at two ends of the through hole 03 in a matched mode, and the hob assembly is installed on a hob frame through a mandrel 02 which sequentially penetrates through an inner hole of the gear 05, the hob body 01 and an inner hole of the shaft sleeve 04. The inventors of the present application have found that the above-described conventional structural designs are not ideal during long-term production practices. Firstly, holes need to be punched in the semi-finished hob structure, the production efficiency of the hob is greatly limited due to the limitation of the machining process, and high-quality hardenability materials are difficult to machine, so that the service life of the hob is also limited. Besides the hob body, a gear, a shaft sleeve and a shaft core need to be additionally machined, so that the production process of the hob and the cost of assembly are increased. Finally, due to the arrangement of the shaft hole structure and the consideration of the structural strength of the wall surface of the hob, the size of the hob is limited, so that the working efficiency cannot be improved, the energy is saved, the environment is protected, and a portable mini pencil sharpener cannot be manufactured.
In view of the above, the inventor of the present application has made an intensive study to solve the above problems, and has successfully developed "a novel integral hob structure for a pencil sharpener" in order to solve the problems of the prior art.
Disclosure of Invention
The technical problem to be solved by the utility model is to provide a novel integrated hob structure for the pencil sharpener, which simplifies the processing procedure, reduces the accessories and improves the production efficiency; the volume is reduced, the raw materials are saved by times, and the production cost is reduced; reduce the noise problem because of original axle sleeve drunkenness leads to, improve the stability and the precision of product, increase of service life.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a novel cut integrative hobbing cutter structure that a ware was used, includes the hobbing cutter body, the both ends of hobbing cutter body all be provided with integrated into one piece's axle spare, the hobbing cutter body be solid construction.
the utility model discloses further preferred scheme be hobbing cutter body be cylindric structure, and hobbing cutter body external diameter be 6mm ~ 8 mm.
the utility model discloses further preferred scheme be equipped with many spiral cutting edges rather than even as an organic whole on the surface of hobbing cutter body, the helix angle of hobbing cutter body be 25 ~ 35.
The utility model discloses further preferred scheme: one shaft piece of the hob body is inserted into the hob holder, and the other shaft piece is clamped into the hob holder and then locked.
Compared with the prior art, the utility model has the advantages of no longer adopt traditional hobbing cutter body to beat the shaft hole, through the mounting means of dabber cooperation gear and axle sleeve. The utility model discloses to directly set up integrated into one piece's axle spare at hobbing cutter body both ends, realize the rotation installation of hobbing cutter body through the axle spare. The production and processing of the shaft sleeve, the gear and the core shaft are not needed any more, four accessories are reduced, and the structure is integrated. The processing links are reduced, and the processing cost is reduced. The hob body does not need to be provided with an axial hole, but adopts a solid structure. Traditional hobbing cutter structure is because the setting in shaft hole, need consider the hobbing cutter wall thickness when designing the hobbing cutter body, and the structural strength and the life of product will be influenced to too thin hobbing cutter wall thickness. The utility model discloses a hobbing cutter design then need not to consider the hobbing cutter wall thickness, can realize producing the hobbing cutter of small-size miniature, can reduce material cost by times. Also because need not to punch on the hobbing cutter body again, the hobbing cutter body can adopt high-quality hardenability material to process, further improves the practical life of hobbing cutter.
Drawings
FIG. 1 is a schematic structural diagram of a conventional hob;
FIG. 2 is a schematic structural view of the present invention;
Fig. 3 is a cross-sectional view of the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 2 to 3: the utility model provides a novel cut integrative hobbing cutter structure that a ware was used, includes hobbing cutter body 1, and hobbing cutter body 1's both ends all are provided with integrated into one piece's axle piece 2, and hobbing cutter body 1 is solid construction.
the hob body 1 is of a cylindrical structure, and the outer diameter of the hob body 1 is 6mm ~ 8 mm.
the outer surface of the hob body 1 is provided with a plurality of spiral blades which are connected with the hob body into a whole, and the spiral angle of the hob body 1 is 25 degrees ~ 35 degrees.
One shaft part 2 of the hob body 1 is inserted into the hob head, and the other shaft part 2 is locked after being clamped into the hob head.
The utility model discloses a structure setting can produce and obtain small-size, miniature hobbing cutter to design into small-size, miniature with whole ware of cutting, can realize cutting the ware and pack into pencil box.
As shown in fig. 1: when the traditional hob structure is installed, a mandrel sequentially penetrates through the upper end of a hob rest, the gear 05, the hob body 01, the shaft sleeve 04 and the lower end of the hob rest to achieve installation of the hob. So the utility model discloses a hobbing cutter body 1's both ends set up integrated into one piece's axle 2's structure, and the problem that the knife rest can't be installed to the adoption traditional mode exists naturally. Therefore, the utility model relates to a hobbing cutter body 1 one of them axle piece 2 inserts the knife rest, and another axle piece 2 card is gone into behind the knife rest lock solid. Set up mounting hole and mounting groove on the knife rest and realize the installation the utility model discloses a hobbing cutter.
The utility model discloses left out the structure of the gear on the hobbing cutter, adopted outer drive gear directly and the meshing of spiral cutting edge, driven the utility model discloses rotate work.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
