The invention has the advantages that, abandoned the method for traditional employing drill bit finished edge, adopt special twolip knife plate to process circular groove with 90 ° of angles, can guarantee the size of circular groove, and knife plate is installed on the knife bar of supporting setting, knife bar is installed on the drilling machine, drive the knife bar rotation by drilling machine and drive the knife plate rotation then, carry out the cutting of groove, the difficult generation of knife plate rocked like this, can guarantee the surface quality of circular groove.In addition, height is installed on the knife bar can measures the degree of depth of circular groove so at any time, thereby conveniently judge whether the groove size meets the demands with the scale of groove depth adjustment.
Description of drawings
Fig. 1 is 90 ° of circular chamfering device overall structure schematic diagrames of the present invention;
Fig. 2 be among Fig. 1 A to schematic side view;
Fig. 3 be among Fig. 1 B to schematic side view;
Fig. 4 is a partial schematic sectional view among Fig. 1.
The specific embodiment
Shown in Fig. 1-4,90 ° of circular chamfering devices of the present invention comprise a white steel knife plate 1, and this knife plate has the both sides blade, and the angle of this both sides blade is 90 °.White steel knife plate 1 is fixed on the white steel knife plate holder 6 by two fastening bolts 5, and two fastening bolts 5 be vertically to arrange point-blank, can guarantee that like this knife plate 1 can not press from both sides 6 with knife plate and relatively move, and knife plate presss from both sides 6 and is connected to the thicker end of knife bar 4.
As shown in Figure 4, the end top that knife plate folder 6 does not connect knife plate is processed with threaded semicircle orifice, and knife bar 4 thicker end centres are processed with two horizontal slotted holes that are parallel to each other, think with these two slotted holes in the knife bar 4 corresponding to be and knife plate presss from both sides 6 and mates long recess, knife plate folder 6 is embedded in this groove, and being fixed in the groove of knife bar 4 by two bolts 7, above-mentioned two fastening bolts 7 are installed on respectively in the slotted hole, are convenient to knife plate folder move left and right like this.Knife plate folder upper end is processed with threaded semicircle orifice, and there is the semicircle unthreaded hole at the knife bar place that cooperates with knife plate folder upper surface, they the two cooperatively interact, form the bolt hole that adjusting bolt 10 is installed.The rotation of regulating bolt 10 can drive knife plate folder 6 along the slotted hole move left and right, thereby regulates the position of knife plate 1, makes that knife plate 1 will be about the center line symmetry of knife bar 4.Copper catch 8 with the adjusting bolt matching is installed regulating the relative knife bar outside of bolt 10 heads, copper catch 8 is fixed on the knife bar outside by two fastening bolts 2, these two trip bolts 2 are point-blank transversely arranged, guarantee 8 fixations of copper catch, can not be moved, and the lower edge of copper catch 8 has the circular hole that matches with the bottom of regulating bolt 10, be used for fixing the slewing area of regulating bolt, place rotational variations, thereby guarantee the center line symmetry of knife plate, guarantee that its circular groove that processes meets the demands about knife bar 4.After regulating the position knife plate is pressed from both sides and the knife bar bolting.Then knife bar is installed on the drilling machine, finishes the processing of 90 ° of circular grooves by the rotation of main shaft.
In addition, above the side of copper catch 8, scale 9 is installed also on the knife bar 4, scale 9 is fixed on the knife bar 4 by two fastening bolts 3, as shown in Figure 2, scale 9 is formed by two sections with bending, and wherein has the tip away from a section of knife bar, 90 ° of angular direction of tip direction and knife plate are consistent, another section of scale is fixed on the knife bar, be close to knife bar, and this segment mark chi is processed with strip hole, fastening bolt 3 is installed in this strip hole, makes scale to slide on fastening bolt 3.
Apparatus of the present invention during use, are installed in knife bar on the drilling machine, then hand mill white steel knife plate and scale are installed on the knife bar, use jackscrew that knife plate is fastening.Jackscrew is used for fixing knife plate, and knife plate is 90 ° of circular grooves of blade processing of 90 ° by its both sides angle.The height of scale can be with the Height Adjustment of groove, and the main effect of scale is the degree of depth of measuring 90 ° of circular grooves.Add man-hour, drill press spindle drives knife bar and rotates, and drives knife plate then and rotates, and carries out the cutting of groove, judges to the distance of surface of the work whether the degree of depth of groove satisfies dimensional requirement according to scale during cutting.Knife plate fixes on the knife plate clamping by bolt.The knife plate folder is connected by bolt with knife bar, is processed with slotted hole on the knife bar, is convenient to knife plate folder move left and right.There is threaded semicircle orifice knife plate folder upper end, and there is the semicircle unthreaded hole at the knife bar place that cooperates with knife plate folder upper surface.When regulating the bolt rotation, knife plate folder meeting move left and right, the position of regulating knife plate makes knife plate about knife bar center line symmetry.After regulating the position knife plate is pressed from both sides and the knife bar bolting.Then knife bar is installed on the drilling machine, finishes the processing of 90 ° of circular grooves by the rotation of main shaft.
The above; only be the preferable specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
