Abstract
The utility model is related to a kind of frock finishing guide pin bushing, including neck bush, external bushing, straight pin, spacer, nut and deep groove ball bearing, the external diameter of neck bush matches with the internal diameter of external bushing, the internal diameter of neck bush is matched with knife bar, spacer is arranged between neck bush and external bushing, and spacer is fixed with external bushing by straight pin, and nut is connected with neck bush, neck bush and external bushing assemble integral by deep groove ball bearing, are separated and are connected by nut using spacer between deep groove ball bearing.The Advantageous Effects that the utility model is obtained are that the frock finishing guide pin bushing reduces the friction of preceding leading axle and bearing liner, improves machining accuracy, extends service life.Good to equipment and cutter protection, the holes of products for processing meets the requirements.
Description
Technical field
The utility model is related to frock processing technique field, more particularly to a kind of frock finishing guide pin bushing.
Background technology
The finishing in hole is bored using unit head or auto-feed, it is necessary to product is adjusted to after perfect condition on aircraft
It is processed using forward and backward guiding, in processing, when operating is bored in unit head or auto-feed, due to the difference of rotating speed, meeting
There is certain axial runout, cause former guide pin bushing with cutter shaft firmly to hard directly contact, not only have infringement mutually to both, and
Reduce both service life.Cause the hole site for machining to shift, influence the Working position precision in hole.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of frock finishing guide pin bushing, the guide pin bushing is solid to cutter shaft
It is fixed firm, prevent displacement.
A kind of frock finishing guide pin bushing, including neck bush, external bushing, straight pin, spacer, nut and deep groove ball bearing,
The external diameter of neck bush matches with the internal diameter of external bushing, and the internal diameter of neck bush is matched with knife bar, spacer be arranged on neck bush with it is outer
Between bushing, spacer is fixed with external bushing by straight pin, and nut is connected with neck bush, and neck bush and external bushing pass through deep-groove ball
Bearing assembling is integral, is separated and is connected by nut using spacer between deep groove ball bearing.
The Advantageous Effects that the utility model is obtained are that the frock finishing guide pin bushing reduces preceding leading axle and bearing
The friction of liner, improves machining accuracy, extends service life.It is good to equipment and cutter protection, the product for processing
Hole meets the requirements.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1, neck bush；2nd, external bushing；3rd, straight pin；4th, spacer；5th, nut；6th, deep groove ball bearing.
Specific embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining practical new
Type, is not intended to limit scope of the present utility model.
Frock finishing guide pin bushing includes external bushing 2, spacer 4, deep groove ball bearing 6, nut 5, and external bushing 2 is by tightening
Screw is fixed in model drilling body, and external bushing 2 is fixed with the external diameter of deep groove ball bearing 6, between deep groove ball bearing 6 by spacer 4 every
Open.Deep groove ball bearing 6 is positioned by spacer 4, nut 5.The characteristics of guide pin bushing, is fixed by external bushing 2, bearing liner with plus
Leading axle is rotated together before and after work knife, reduces the friction of preceding leading axle and bearing liner, improves machining accuracy, and extending makes
Use the life-span.
The finishing in hole is bored using unit head or auto-feed, it is necessary to product is adjusted to after perfect condition on aircraft
It is processed using forward and backward guiding, in processing, when operating is bored in unit head or auto-feed, due to the difference of rotating speed, meeting
There is certain axial runout, cause former guide pin bushing with cutter shaft firmly to hard directly contact, not only have infringement mutually to both, and
Reduce both service life.Cause the hole site for machining to shift, influence the Working position precision in hole.This moves about
Guide pin bushing can realize unstressed axial feed of the product in perfect condition, it is ensured that holes of products after the completion of finishing, product space shape
State it is consistent, so as to ensure the positional precision of hole machined.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
Some that to be made to some of which part variations embody principle of the invention, belong to protection scope of the present invention it
It is interior.
