Abstract
The utility model relates to a kind of hilted broadsword boring boring bar, comprise knife bar, the bottom of knife bar is arranged with two main shaft connecting holes parallel with knife bar central axis, the head of knife bar is provided with cutter groove, cutter groove center line and knife bar central axis shape a in an angle, and the size of angle a is identical with the anterior angle of cutter, the top end face of knife bar is provided with chip area, chip area along knife bar central axis extend to inward cutter groove place and and cutter groove communicate, knife rod head surface is provided with and communicates with cutter groove and the cutter housing pin hole vertical with cutter groove.Cutter groove center line and knife bar central axis have an angle a, can improve the anterior angle that increases cutter, make cutter and knife bar in cutting process, improve the holding capacity of knife bar, increase the stability of processing dimension.
Description
Technical field
The utility model belongs to Machining Technology field, is specifically related to a kind of hilted broadsword boring boring bar.
Background technology
In the processing of the hole of machine-building, can carry out Boring with hole boring cutter, in process, surface of the work is passed to after boring cutter bar the reaction force of boring cutter, can make boring cutter bar produce vibration radially.While particularly carrying out deep hole machining, because cutting vibration is large, both affect the crudy of workpiece hole, affected again the service life of cutter.
Utility model content
In order to overcome the defect of prior art, the utility model provides a kind of hilted broadsword boring boring bar.
Based on above-mentioned purpose, the utility model has been taked following technical scheme:
A kind of hilted broadsword boring boring bar, comprise knife bar, the bottom of knife bar is arranged with two main shaft connecting holes parallel with knife bar central axis, the head of knife bar is provided with cutter groove, cutter groove center line and knife bar central axis shape a in an angle, and the size of angle a is identical with the anterior angle of cutter, the top end face of knife bar is provided with chip area, chip area along knife bar central axis extend to inward cutter groove place and and cutter groove communicate, knife rod head surface is provided with and communicates with cutter groove and the cutter housing pin hole vertical with cutter groove.
The utility model makes cutter groove center line and knife bar central axis have an angle a, and the size of angle a is identical with the anterior angle of cutter, can improve the anterior angle that increases cutter, make cutter and knife bar in cutting process, improve the holding capacity of knife bar, increase the stability of processing dimension.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the P-P cutaway view of Fig. 1;
Fig. 3 is the N-N cutaway view of Fig. 1.
Detailed description of the invention
As shown in Figure 1,2 and 3, a kind of hilted broadsword boring boring bar, comprise knife bar 2, the bottom of knife bar 2 is arranged with the main shaft connecting hole 1 parallel with knife bar central axis, the head of knife bar 2 is provided with cutter groove 4, cutter groove 4 center lines and knife bar 2 central axis shape a in an angle, and the size of angle a is identical with the anterior angle of cutter, the top end face of knife bar 2 is provided with chip area 3, chip area 3 along knife bar 2 central axis extend to inward cutter groove 4 places and and cutter groove 4 communicate, knife bar 2 head surfaces are provided with and communicate with cutter groove 4 and the cutter housing pin hole 5 vertical with cutter groove 4.
When use, Cutting tool installation manner, to cutter groove 4, is fastened on cutter in cutter groove 4 by the screw in cutter housing pin hole 5, drains from chip area 3 adding the iron filings that machine away man-hour, reduce because of the unfavorable dimension overproof because rising of iron filings chip removal.
