Abstract
Flat cutter is drawn, including knife bar, cutter head, blade in the open a kind of back side, hole of this utility model；The rod end of described knife bar is threaded, and also sets up pillow block portion；Cutter head is threaded hole, the insert groove of radial direction and screw；The screwed hole of cutter head is threadeded with knife bar；Blade embeds in insert groove, and is fixed in the screw of cutter head through the through hole in the middle of blade by bolt.The utility model has the advantages that: adding man-hour blade easy to loading and unloading, knife bar is multidiameter shape, guaranteeing in the case of processing hole, increasing the diameter of knife bar as far as possible, therefore, the intensity of knife bar is preferable；Column type insert groove can ensure to add the radial displacement in man-hour within the limits prescribed, this improves machining accuracy.
Description
Technical field
This utility model relates to field of machining, specifically the back side process tool of cylindrical hole.
Background technology
In machining, the end face in hole needs to process a plane for installing bolt, and due to front, to there is interference etc. former
Cause, it is necessary to the situation drawing average from back side upper slitter is the most common.Existing anti-stroke of flat cutter mainly has two kinds of form: Yi Zhongshi
Knife bar end is installed blade, and this cutter is longer owing to blade stretches out, poor rigidity, needs to reduce cutting force, thus reduces efficiency,
And blade easily damages；Another kind is welding type cutter head, and this cutter is in the case of aperture is less, and welding quality cannot be protected
Card, blade is easy to fall off.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of back side, hole and draws flat cutter, including knife bar,
Cutter head, blade；The rod end of described knife bar is threaded, and also sets up pillow block portion；Cutter head is threaded hole, the insert groove of radial direction and spiral shell
Hole；The screwed hole of cutter head and the threaded of knife bar also ensure that cutter head abuts with pillow block portion；The screwed hole of cutter head and the spiral shell of knife bar
Stricture of vagina connects；Blade embeds in insert groove, and is fixed in the screw of cutter head through the through hole in the middle of blade by bolt.
For ease of the handling of cutter head, the outside of cutter head arrange symmetry groove, correspondingly, the bottom of knife bar be also provided with for
The fluting of spanner clamping.
For ensureing to add the locking of the radial displacement of blade in man-hour, described insert groove is cylinder groove；The bottom shape of blade with
Insert groove is corresponding；Radial displacement can be ensured by the gap between cylinder groove and insert bottom cylinder.
The utility model has the advantages that: adding man-hour blade easy to loading and unloading, knife bar is multidiameter shape, is guaranteeing through adding
In the case of work hole, increasing the diameter of knife bar, therefore, the intensity of knife bar is preferable as far as possible；Column type insert groove can ensure to add man-hour
Radial displacement within the limits prescribed, this improves machining accuracy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is explosive view of the present utility model.
Detailed description of the invention
Illustrate this utility model below in conjunction with the accompanying drawings, as Figure 1-Figure 2, including knife bar 2, cutter head 1, blade 3；Institute
The rod end stating knife bar 2 is threaded, and also sets up pillow block portion 5；Cutter head is threaded hole, the insert groove 6 of radial direction and screw 7；Cutter head
Screwed hole and the threaded of knife bar and ensure that cutter head abuts with pillow block portion；Blade 3 embeds in insert groove 6, and is worn by bolt 4
Cross the through hole in the middle of blade to be fixed in the screw 7 of cutter head.
For ease of the handling of cutter head, the outside of cutter head arranges the groove 8 of symmetry, and correspondingly, the bottom of knife bar is also provided with using
Fluting 9 in spanner clamping.
For ensureing to add the locking of the radial displacement of blade in man-hour, described insert groove is cylinder groove；The bottom shape of blade with
Insert groove is corresponding；Radial displacement can be ensured by the gap between cylinder groove and insert bottom cylinder.
Using method of the present utility model is: first processes through hole with fluted drill, then is stretched into by knife bar in through hole, installs cutter
Head, then starts lathe, and upwards feed completes cutting, after machining, is unloaded by cutter head with spanner.
