Abstract

The utility model relates to an axle component of a rubber roller of a gravure printing machine, in particular to an axle driving component of the rubber roller of the gravure printing machine. The axle driving component adopts the technical proposal that the axle driving component of the rubber roller of the gravure printing machine comprises an axle hole and a thimble, the axle hole is arranged on the axle body, the shape of the axle hole adopts an inwardly concave cone-shaped hole, and the thimble adopts a cone corresponding to the inwardly concave cone-shaped hole, wherein, grooves are arranged at the inner side of the outer edge near to the cone base of the cone-shaped hole; convex blocks are arranged at the outer side of the outer edge near the cone base of the cone-shaped hole; the convex blocks are inosculated with and are corresponding to the grooves. The axle driving component has the advantages that because the convex blocks are inosculated with and are corresponding to the grooves, the jacking between the thimble and the axle hole can be stronger. If the convex blocks and the grooves are not arranged, skidding can easily occur on the jacking between the thimble and the axle hole.

Description

The axle driver part of gravure printing machine rubber roll

Technical field

The utility model relates to the parts of the axle of gravure printing machine rubber roll.Especially gravure printing machine rubber roll the axle driver part.

Background technology

The axle of gravure printing machine rubber roll is thinner because of various reasons, the axle core of traditional gravure printing machine rubber roll is to mill a bellmouth mostly, the driving processing operation principle of axle is to utilize the thimble of lathe to cooperate with the bellmouth of axle core, admittedly the friction that produces by this strong top drives, but friction is too little, and axle one is skidded by resistance easily.

Gravure printing machine rubber roll is a kind of common axle base part, and it needs to remove thoroughly after certain hour is used in printing and cleans, and printing machine rubber roll quantity is many, and cleaning need be finished in time the inside faster.Can be difficult to carry out with claw the rotation driving of rubber roll again in carrying out cleaning process, cleaning is to carry out in the production scene, and is also inconvenient with heavy lathe, and this just brings certain difficulty to driving the rubber roll rotation.

Summary of the invention

The purpose of this utility model provides a kind of axle driver part of gravure printing machine rubber roll.

The technical solution of the utility model has following:

The axle driver part of gravure printing machine rubber roll comprises axis hole and thimble, and axis hole is arranged on the axis body, and axis hole is shaped as the round taper hole that concaves, and thimble is the cone corresponding with the round taper hole that concaves; Wherein: be provided with groove near inboard place, outer at the bottom of the awl of round taper hole; Be provided with projection near the outside, outer at the bottom of the awl of cone; Projection coincide corresponding with groove.

Advantage of the present utility model is: because that projection and groove match is corresponding, so the top between thimble and the axis hole is stronger admittedly.If projection and groove are not set, skid admittedly easily in the top between thimble and the axis hole.

In the process of tradition axle, the two ends of axle generally all are milled with bellmouth, to be convenient to processing under the location of lathe thimble drives, particularly when axle can't utilize claw or other method to drive, the bellmouth at the two ends of axle is that unique location drives link, the process of axle is exactly to utilize the thimble of lathe solid with the strong top of bellmouth of axle, thereby the friction that produces admittedly by this strong top and driving, and to have the solid power in strong top just must have heavy lathe just can accomplish, and general light and easy equipment just can't produce the solid power in this strong top, want the processing of driving shaft just very difficult, the present invention be exactly axle the outer radius of bellmouth mill a flat recess, thereby and process a projection on the thimble head and match with the flat recess of the outer radius of bellmouth and make lathe and the general light and easy equipment can both driving shaft and conveniently process.So we have designed in the taper hole place punching press on axle core both sides or have milled a flat recess, utilize the projection that processes on the thimble head to drive rubber roll with regard to using general light and easy equipment.

The specific embodiment

The axle driver part of embodiment 1, gravure printing machine rubber roll comprises axis hole and thimble, and axis hole is arranged on the axis body 3, and axis hole is shaped as the round taper hole 1 that concaves, and thimble is the cone 4 corresponding with the round taper hole that concaves 1; Wherein: be provided with groove 2 near inboard place, outer at the bottom of the awl of round taper hole 1; Be provided with projection 5 near the outside, outer at the bottom of the awl of cone 4; Projection 5 matches corresponding with groove 2.

Because it is corresponding that projection 5 and groove 2 match, so the top between thimble and the axis hole is stronger admittedly.If projection 5 and groove 2 are not set, skid admittedly easily in the top between thimble and the axis hole.

Claims

1, the axle driver part of gravure printing machine rubber roll comprises axis hole and thimble, and axis hole is arranged on the axis body (3), and axis hole is shaped as the round taper hole (1) that concaves, and thimble is the cone (4) corresponding with the round taper hole that concaves (1); It is characterized in that: be provided with groove (2) near inboard place, outer at the bottom of the awl of round taper hole (1); Be provided with projection (5) near the outside, outer at the bottom of the awl of cone (4); Projection (5) matches corresponding with groove (2).
