Abstract
The invention relates to a knife shell with keep-space in the outer diameter of an installation end surface, wherein a central hole for installing a knife shaft is in the center of the knife shell, and the end surface is an installation end surface contacted with the knife shaft. The invention is characterized in that keep-space is arranged in the outer diameter of the installation end surface, and the installation end surface and the outer side of the knife shell form step or chamfer transition. Thus, if the knife shell collides with other parts, only the outer side of the knife shell is damaged, the installation end surface can not be damaged, and the assembly accuracy is ensured.
Description
Technical field
The present invention relates to a kind of cutter shell of mounting cutter, specifically relate to a kind of cutter shell that the empty avoiding of end face external diameter band is installed, belong to the Machining Technology field.
Background technology
In machining, cutter is necessary parts, so installing and fixing of cutter also is a very important structure.Cutter is installed on the cutter shell, and tail end inserts in the centre bore of cutter shell, fixedly mounts again.Installation end face on the cutter shell is the plane of an integral body, and the installation accuracy of stage property is that very strict requirement is arranged.Therefore very high to flatness and required precision that end face is installed.But; because being installed, end face when design, has certain pre-allowance; perhaps because the outflow of some smear metals is arranged; enter between cutter shell and other parts; in the motion process of cutter shell; cause the cutter shell to contact, collide with other parts through regular meeting, can cause distortion, damage that end face is installed, serious meeting causes installs the end face protuberance.Because it is the part that directly contacts installation with cutter shaft that end face is installed, if the end face out-of-flatness is installed, during installation, installs between end face and the cutter shaft and just can not contact fully, can cause the cutter shaft installation not in place, influence installation accuracy.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind ofly to be provided with the cutter shell of empty avoiding,, also can not be damaged to the installation end face even cutter shell and other parts bump at the installation end face external diameter of cutter shell, improve assembly precision, guaranteed the use of cutter shell.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of cutter shell that the empty avoiding of end face external diameter band is installed, be provided with the centre bore that is used to install cutter shaft at the center of described cutter shell, the end face of cutter shell is the installation end face that contacts with cutter shaft, it is characterized in that outer radius at described installation end face, be provided with empty avoiding, form step or chamfering transition between the lateral surface of installation end face and cutter shell.
The invention has the beneficial effects as follows: the present invention is provided with empty avoiding in the outer radius of the installation end face of cutter shell, just step or chamfering etc. are set at transition position with the lateral surface of cutter shell, even cutter shell and other parts bump like this, what damage also is the lateral surface of cutter shell, and can not be damaged to the installation end face, guaranteed assembly precision.
Description of drawings
Fig. 1 is the structural representation of cutter shell of the prior art;
Fig. 2 is the structural representation of the cutter shell among the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done concrete introduction.
Fig. 2 is the structural representation of the cutter shell among the present invention.
As shown in the figure, 1 is the cutter shell among the figure, and 2 is centre bore, and 3 are empty avoiding.The centre of cutter shell 1 of the present invention is provided with centre bore 2, is used to install cutter shaft.Transition position at the lateral surface that end face and cutter shell 1 are installed is provided with empty avoiding 3; just be provided with the empty avoiding of forms such as chamfering, step at the transition position of the lateral surface that end face and cutter shell 1 are installed; certainly empty avoiding also can be other form; this is not carried out special qualification at this; the empty avoiding of other form that those skilled in the art draws according to the application's thought also should be considered as in the application's protection domain.
Because the transition position at the lateral surface that end face and cutter shell 1 are installed is provided with empty avoiding 3, in the motion process of cutter shell, even because the pre-allowance or the smear metal in the process of the design of cutter shell have entered between cutter shell and the parts, cutter shell and other parts bump, friction etc., the damage of tool setting shell also is the lateral surface of cutter shell, can not be damaged to the installation end face, the phenomenon that end face can not deform or swell is installed, can not have influence on the installation of cutter shaft, improved the assembly precision of cutter shaft greatly, reduce work hours, improved operating efficiency.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
