Abstract
The utility model discloses a mechanical clamped insection type drill which comprises a cutter body 1 and a cutter blade 2, wherein, the cutter body 1 is provided with a cutter blade groove, the cutter blade 2 is fixedly arranged in the cutter blade groove and fixed by a fastening bolt 3, the radial direction of the cutter blade 2 in the cutter blade groove is positioned by a section positioning mechanism 10 on the cutter body 1 and a jugged positioning mechanism 8 on the cutter blade 2, the cutter body 1 is provided width a cooling hole 11 and a cuttings chute 12, the cutter blade 2 is provided with two groups of cutting blades which are symmetrical and a transverse blade 4, and each group of cutting blades is composed of two wavy blades 5 and 6 and a straight slick blade 7. The utility model has the advantages that the cutter blade can be sharpened, thereby the utilization rate is enhanced; the cutter blade adopts the insection embedded type positioning structure, thereby the repeatable positioning of high precision is guaranteed; the cutting blades are of wavy shapes, the cutting is ensured to be smooth; one bolt is used for pressing, so the cutter blade can be changed only by screwing off the bolt, thereby the assembly and the disassembly are facilitated; the manufacture cost is low, and the structure is simple.
Description
Technical field
The utility model relates to a kind of drill bit, particularly a kind of machine folder groove formula drill bit.
Technical background
At present, domestic employed machined drill bit mainly contains four classes: at a high speed firm solid drill, solid carbide drill, machine clip variable-position blade type drill bit, interchangeable cutter head formula drill bit.At the bottom of the high-speed steel drill rotating speed, at the bottom of the production efficiency, durability is low, the cost height; Solid carbide drill, the cost height of material is unfavorable for saving energy and reduce the cost, and simultaneously, process equipment requires high; Machine clip variable-position blade type drill bit is to designing technique and processed environmental requirement height, processing effect instability; Interchangeable cutter head formula drill bit, because cutter head and cutter hub are mechanical connection, cutter hub self poor rigidity can not normally be used at the environment of process system poor rigidity; Clamped cutting bit chip drill bit, blade and cutter hub are screw and groove location, and position stability is poor, and blade is fragile.
Summary of the invention
The purpose of this utility model promptly is to overcome the deficiencies in the prior art, provides a kind of precision to keep, stable cutting, but blade sharpening usefulness again, and the machine folder groove drill bit that the production difficulty is less relatively, it is simple in structure and easy to loading and unloading, stable, the durability height.
The purpose of this utility model is achieved through the following technical solutions: clamped cutting bit chip drill bit, it is by cutter hub, blade, cutter hub is provided with insert groove, blade is installed in the insert groove and is fixed by trip bolt, the radial position of blade in insert groove is by zigzag detent mechanism location on groove detent mechanism and the blade on the cutter hub, cutter hub is provided with cooling hole and chip area, cooling fluid injects directly on the high hot zone of cutter hub and blade through the cooling hole, chip area is a straight trough, it also can be helicla flute, blade is provided with cutting edge and chisel edge of two groups of symmetries, and every group of cutting edge is made up of two undaform swords and a straight wiper edges.
Serrated slot on blade and the cutter hub is opened along cutter axis of rotation direction, and blade embeds insert groove along the cutter hub axis, and the axial location of blade is by the axial end restriction of insert groove.
The determined type sword of the intersection that described undaform sword is the inclined-plane and the conical surface.
The utlity model has following advantage: blade can sharpening, has improved the utilization rate of blade; Blade adopts the embedded location structure of groove, has guaranteed high-precision resetting; Cutting edge is a wave sword type, guarantees stable cutting; A screw in compression, unscrewing screw is replaceable blade, is convenient to loading and unloading; Low cost of manufacture, simple in structure.

Among the figure: the 1-cutter hub, the 2-blade, 3-trip bolt, the chisel edge on the 4-blade, a undaform sword in close axle center on the 5-blade, another undaform sword on the 6-blade, a straight wiper edges on the 7-blade, zigzag detent mechanism on the 8-blade, the axle head locating surface of 9-cutter hub upper slitter film trap, groove detent mechanism on the 10-cutter hub, 11-cools off hole, 12-chip area.
The specific embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing: as Fig. 1~Fig. 4, machine folder groove formula drill bit, it is by cutter hub 1, blade 2, cutter hub 1 is provided with insert groove, blade 2 is installed in the insert groove fixing by trip bolt 3, the radial position of blade 2 in insert groove is by 8 location of zigzag detent mechanism on groove detent mechanism 10 on the cutter hub 1 and the blade 2, cutter hub 1 is provided with cooling hole 11 and chip area 12, blade 2 is provided with cutting edge and chisel edge 4 of two groups of symmetries, and every group of cutting edge is made up of 5,6 and straight wiper edges 7 of two undaform swords.
Serrated slot on blade 2 and the cutter hub 1 is opened along cutter axis of rotation direction, and blade 2 embeds insert groove along the cutter hub axis, and the axial location of blade 2 is by axial end 9 restrictions of insert groove.
Described undaform sword the 5, the 6th, the determined type sword of the intersection of the inclined-plane and the conical surface.
