Detailed description of the invention
Consult Fig. 1 and Fig. 2, the brill that the utility model provides, boring, car multifunction turning instrument, comprise the fixed part 11 for being connected with lathe tools installation site, connecting portion 12 and cutter head 13, one end of connecting portion 12 is fixedly connected with fixed part 11, and cutter head 13 is fixed on the other end of connecting portion 12; Connecting portion 12 is provided with material returned groove, cutter head 13 is fixed on the end of material returned groove, it is point of a knife that cutter head 13 is provided with parallel with connecting portion 12 end face and the first cutting edge 131 leant out from end face and second cutting edge 132, first cutting edge 131 vertical with the first cutting edge 131 and the second cutting edge 132 point of intersection.
The brill that the utility model provides, boring, car multifunction turning instrument, its operation principle is as follows:
Refer to Fig. 3-6, cutter head 13 is provided with two orthogonal cutting edges, by the dead in line of the axis of cutting tool and workpiece 14, moves horizontally turning instrument first cutting edge 131 and the second cutting edge 132 works simultaneously, can Drilling operation be carried out, and the hole processed had 90 ° flat; First cutting edge 131 is pressed close to workpiece 14 end face, can the end face of processing work 14, play the effect of milling cutter; Connecting portion 12 is inserted endoporus, utilizes the second cutting edge 132 boring workpiece 14 endoporus; In addition, the first cutting edge 131 and the second cutting edge 132 is utilized also can to process the cylindrical of workpiece 14.
The brill that the utility model provides, boring, car multifunction turning instrument, cutter head 13 is provided with two orthogonal cutting edges, a cutter is utilized to realize the several functions such as boring, bore hole, processing work 14 end face and processing work 14 cylindrical, lathe only need arrange a Cutting tool installation manner position, reduce production cost and the volume of lathe; When carrying out different operations, not needing to change different cutters, reducing operation easier, saving the time changing cutter, improve working (machining) efficiency; And three cutter heads 13 before replacing with a cutter head 13, can save the use cost of cutter head 13; In addition, connecting portion 12 is provided with material returned groove, the waste material produced in working angles, is discharged in time by material returned groove, avoid waste material to disturb the stock removal action of cutter head, make machined surface flat smooth.
Specifically, the brill that the utility model provides, boring, car multifunction turning instrument, have two kinds of embodiments.
First embodiment, refers to Fig. 1, is applicable to the cutter that diameter is less than the minor diameter of 8mm, adopts whole hard alloy material, and fixed part 11, connecting portion 12 and cutter head 13 are formed in one structure.The cutting tool of this embodiment, structure is simple, and manufacture difficulty is low, economical and practical, but this structure is only applicable to and small-diameter cutter, when the diameter of cutter increases, the area of cutting edge also increases, higher to the requirement of strength of cutting edge, and therefore this integrated structure is difficult to meet the demands.
Second embodiment, refers to Fig. 2, is applicable to the large diameter cutter that diameter is greater than 8mm, adopts indexable insert tip, throw away tip to add the combining form of cutter body.Namely fixed part 11 and connecting portion 12 are formed in one structure, and cutter head 13 is fixed on the end of connecting portion 12 by trip bolt.Specifically, the end of connecting portion 12 is provided with limited step, cutter head 13 is flat cuboid, cuboid comprise connect successively the first side, the second side, the 3rd side and the 4th side, first side is provided with the first cutting edge 131, second side is provided with the second cutting edge the 132, three side or the 4th side is against on limited step.
In the present embodiment, cutter head 13 and connecting portion 12 are separable structure, and tool has the following advantages:
1, because cutter head 13 is wear-out part, the cutter head 13 that more can renew when cutter head 13 serious wear, and do not need to change whole cutter, save the use cost of cutter;
2, when the size of cutter head 13 is larger, can transport or off working state time, by rotary cutter 13, make cutting edge inwardly instead of lean out cutter, therefore better can protect cutting edge, cutting edge also can be avoided surprisingly to hurt sb.'s feelings.
In both embodiments, these cutting tool are provided with cooling passage, and cooling passage runs through fixed part 11 and connecting portion 12, and the openend of cooling passage is connected with lathe cooling system, and the port of export points to cutter head 13.The built-in cooling passage of cutting tool, convenient coordinating with cooling device, cools working position adding, can extend cutting-tool's used life man-hour.
In both embodiments, the edge of the material returned groove on connecting portion 12 is helical form.The conditioner of said structure, make the waste material that produces in working angles in the same direction at a high speed fly away from cutter, avoid cutting edge to cut waste material and cause cut surface coarse, ensure cut quality.
In both embodiments, connecting portion 12 is provided with multiple for the convenient screens 111 be fixedly connected with lathe tools installation position.The clamping screens 111 of lathe tools installation position, realizes the fixing of cutting tool, avoids cutting tool to skid, improve the reliability of equipment work.
These are only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
