Abstract
The utility model relates to a clamping regrinding type excircle lathe tool, belonging to the mechanical processing tool. The clamping regrinding type excircle lathe tool comprises a knife tool and a knife bar. The upper surface of the knife bar is provided with a knife slot which can place a cuboid knife tool. The left and right sides of the knife slot are parallel, and the bottom surface and the horizontal direction form an angle of inclination alpha . The left and right sides of the knife slot and the right side of the knife bar form an included angle beta . The left side and right side of the knife bar form an included angle beta /2. The main cutting edge and the minor cutting edge of the knife tool head extend out of the knife bar, and the right side of the knife slot of the knife bar head is provided with a bolt hole. The knife tool are fastened in the knife slot through a knife tool press pad and screw nails, and the bottom surface of the knife tool is provided with an angle of inclination matching with the knife slot. The knife tool of the clamping regrinding type excircle lathe tool of the utility model is installed in the knife slot of the knife bar, and the knife tool is fastened and connected to the knife bar by screw nails and the knife tool press pad. The bottom surface of the knife bar is provided with an angle of inclination, so the fastening effect of the knife tool and the knife bar is good, and the cutting performance of the knife tool is stable. The tool dimensions can be lengthened, the tool grinding is safe and reliable, and the service life is long.
Description
Technical field
The utility model relates to a kind of clamping regrinding type billmpse tool, belongs to machine tools.
Background technology
Lathe tool is the key tool of turning processing, and commonly used have soldering lathe tool, machine folder reface lathe tool and a machine folder throw away bit etc.The soldering lathe tool is that cutter is welded on the knife bar head, thereby can reduce the cutting ability of cutter, during sharpening, promptly wants the sharpening cutter, the bar of whetting a knife again, and the sharpening time is long, occurs " burning cutter " phenomenon again easily, and waste knife bar material.And the machine folder is refaced and the tool dimension of throw away bit is little, and service life is short; And during hand grinding, hand and emery wheel are very near from getting, and security incident takes place easily.
The utility model content
The utility model provides a kind of sharpening of being convenient in order to overcome the defective of prior art, and the clamping regrinding type billmpse tool of long service life.
The utility model clamping regrinding type billmpse tool comprises cutter and knife bar; Wherein the upper surface of knife bar is provided with the cutter groove of laying the cuboid cutter, and cutter groove left and right sides face is parallel, and its bottom surface and horizontal direction have an inclination alpha; The angle of cutter groove left and right sides face and knife bar right flank is β, and the left surface of knife bar and the angle of right flank are β/2; The main cutting edge of cutter head and a pair cutting edge stretch out outside the knife bar; The cutter groove right side of knife rod head has screw, by cutter pressure pad and screw cutter is fastened in the cutter groove, and the bottom surface of cutter is provided with the inclination angle and cooperates with the cutter groove.
The utility model clamping regrinding type billmpse tool, wherein inclination alpha is 25 °～35 °; Angle β is 4 °～8 °.
The utility model clamping regrinding type billmpse tool, wherein the cutter pressure pad is quadrangle or pentagon, is that line contacts with the contact position of cutter.
The utility model clamping regrinding type billmpse tool wherein also is added with edge bearing between tool base and the cutter groove bottom.
The utility model clamping regrinding type billmpse tool, cutter are installed in the cutter groove of knife bar, be fastenedly connected with screw and cutter pressure pad and knife bar, and there is an inclination angle bottom surface of knife bar, thereby cutter and knife bar are fastening effective the Tool in Cutting stable performance.Tool dimension can extend, and sharpening is safe and reliable, long service life.
Description of drawings
Fig. 1 is the front view of the utility model clamping regrinding type billmpse tool structural representation;
Fig. 2 is Fig. 1 left view;
Fig. 3 is the A-A profile of Fig. 1;
Fig. 4 is the B-B profile of Fig. 1.
Specific implementation method
By Fig. 1～Fig. 4 as seen, the utility model comprises knife bar 1, cutter 2 and cutter pressure pad 5 etc.Wherein the upper surface of knife bar 1 is provided with the cutter groove 3 of laying cuboid cutter 2, and the left and right sides face of cutter groove 3 is parallel, and its bottom surface and horizontal direction have an inclination alpha=30 °; The angle of cutter groove 3 left and right sides faces and knife bar 2 right flanks is β=6 °, and the left surface of knife bar 1 and the angle of right flank are 3 °; The main cutting edge of cutter 2 heads and a pair cutting edge stretch out outside the knife bar 1; Cutter groove 3 right sides of knife bar 1 head have screw 4, by cutter pressure pad 5 and screw 6 cutter 2 is fastened in the cutter groove 3, and the bottom surface of cutter 2 are provided with the inclination angle and cooperate with cutter groove 3.
During use, cutter 2 is placed in the cutter groove 3, by selecting the thickness of edge bearing 7, make the height of cutter 2 a little less than cutter groove 3, and cutter is fastened in the cutter groove 3 of knife bar 1 with cutter pressure pad 5 and screw 6, attention is stretched out the main cutting edge of cutter 2 heads outside the cutter groove 3 on the knife bar 1, and knife bar 1 is installed on the knife rest, just can carry out work.Because securing member is fastening, add that in working angles the inclined contact surface of cutter 2 bottom surfaces constitutes the angle of antagonism mutually with cutting direction, so the position between cutter 2 and the knife bar 1 is very firm and stable, guarantees the cutting ability of cutter.Cutter can be longer simultaneously, longer service life.
