Abstract
The utility model relates to boring instruments applied to machine tool machining, in particular to a composite boring tool. The composite boring tool comprises a handle for clamping and a cutting end located at one end of the handle. A rough boring blade, a fine boring blade, a chamfer blade are fixed at the cutting end. A notch is reserved at the cutting end. The fine boring blade is fixed in the notch through a locking mechanism. The handle is clamped to a boring mill. The rough boring blade machines a through hole roughly while the fine boring blade machines the inner wall of the through hole finely, the chamfer blade chamfers the wall at the opening of the through hole, and accordingly the through hole is machined by one step. The composite boring tool is simple in machining procedures, needs no frequent blade changing, guarantees machining precision and improves work efficiency.
Description
Technical field
The utility model relates to the boring instrument that uses in a kind of machine tooling process, is specifically related to a kind of composite boring cutters.
Background technology
In process, need to be on workpiece machining hole, existing manufacturing procedure is to adopt rough boring cutter to carry out the shape that the first time, heavy boring portalled, and then change the right boring blade hole inwall is carried out right boring, change at last the right boring blade, install chamfering blade openings is carried out chamfering, such manufacturing procedure is complicated, frequently tool changing of needs, and trueness error in various degree all can appear in each tool changing, thereby reduced machining accuracy, also reduced working (machining) efficiency simultaneously.
The utility model content
For above-mentioned technical problem, the utility model provides a kind of composite boring cutters, and it once just can finish the processing of through hole, and manufacturing procedure is simple, need not frequent tool changing, guarantees machining accuracy, increases work efficiency.
The realization the technical solution of the utility model is as follows:
A kind of composite boring cutters, the handle of a knife that it comprises for clamping is positioned at the cutting end part of handle of a knife one end, is fixedly installed heavy boring blade, right boring blade, chamfering blade at cutting end part, be provided with breach at cutting end part, the right boring blade is fixed in the breach by retaining mechanism.
Be provided with fixed platform in the described breach, retaining mechanism comprises the right boring blade is pressed on latch segment on the fixed platform, is positioned at the piece that is locked that is fixed in cutting end part of latch segment one side, and an end passes the piece that is locked and withstands on lock-screw on the latch segment.
Be provided with the second lock-screw that locks it in cutting end part on the described latch segment.
Adopted such scheme, handle of a knife is clamped on the boring machine equipment, the heavy boring blade carries out roughing to the hole, simultaneously right boring blade carries out fine finishining to the inwall of through hole, chamfering blade carries out chamfering to the openings wall, thus the disposable processing of finishing through hole, and its manufacturing procedure is simple, need not frequent tool changing, guarantee machining accuracy, increase work efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure, 1 is handle of a knife, and 2 is cutting end part, and 3 is the heavy boring blade, and 4 are the right boring blade, and 5 is chamfering blade, and 6 is breach, and 7 is fixed platform, and 8 is latch segment, and 9 for being locked piece, and 10 is lock-screw, and 11 is the second lock-screw.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Referring to Fig. 1, a kind of composite boring cutters, it comprises the handle of a knife 1 for clamping, be positioned at the cutting end part 2 of handle of a knife 1 one ends, handle of a knife and cutting end part are integrated setting, be fixedly installed heavy boring blade 3, right boring blade 4, chamfering blade 5 at cutting end part, be provided with breach 6 at cutting end part, right boring blade 4 is fixed in the breach by retaining mechanism.Wherein, be provided with fixed platform 7 in the breach 6, retaining mechanism comprises the right boring blade is pressed on latch segment 8 on the fixed platform, is positioned at the piece 9 that is locked that is fixed in cutting end part of latch segment one side, and an end passes the piece that is locked and withstands on lock-screw 10 on the latch segment.Be provided with the second lock-screw 11 that locks it in cutting end part on the latch segment 8.Can change the right boring blade according to the needs of different size, during replacing, turn lock-screw 10, the second lock-screw 11 get final product dismounting and change, and be very convenient.
