Abstract
The utility model relates to a cutter shell with a clearance at the outer diameter of an installation end surface. The center of the cutter shell is provided with a central hole for installing a cutter shaft; and the end surface of the cutter shell is the installation end surface contacted with the cutter shaft. The cutter shell is characterized in that the outer diameter of the installation end surface is provided with the clearance, and a step or a chamfer for transition is formed between the installation end surface and the outer side surface of the cutter shell. In the utility model, the outer diameter of the installation end surface of the cutter shell is provided with the clearance, namely, the step or the chamfer and the like is formed at the transition with the outer side surface of the cutter shell, therefore, even if the cutter shell collides with other parts, only the outer side surface of the cutter shell is damaged, while the installation end surface can not be damaged, thus ensuring the assembly precision.
Description
Technical field
The utility model relates to a kind of cutter shell of mounting cutter, specifically relates to a kind of cutter shell that the empty avoiding of end face external diameter band is installed, and belongs 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.
The utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of and is provided with the cutter shell of empty avoiding at the installation end face external diameter of cutter shell, even cutter shell and other parts bump, also can not be damaged to the installation end face, improve assembly precision, guaranteed the use of cutter shell.
For achieving the above object, the utility model is to realize by following technical scheme:
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 beneficial effects of the utility model are: the utility model 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 in the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done concrete introduction.
Fig. 2 is the structural representation of the cutter shell in the utility model.
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 utility model 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 utility model in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in the protection domain of the present utility model.
Claims (1)
1. the cutter shell of end face external diameter band empty avoiding 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.
