Abstract
The invention relates to the technical field of cutting tools, in particular to a drill bit convenient to disassemble and assemble. The drill bit convenient to disassemble and assemble comprises a drill shank and a drill head. The drill head is arranged under the drill shank. The drill bit convenient to disassemble and assemble is characterized in that the bottom of the drill head is conical; the conical bottom is provided with an arc-shaped groove used for containing removed chips; the drill head is provided with a plurality of spiral cutting edges; a spiral chip groove which is spirally matched with the corresponding cutting edges is formed between every two adjacent cutting edges; the cutting edges and the spiral chip grooves are connected with the arc-shaped groove; a bolt is mounted on the drill head; a slotted hole is formed in the lower portion of the drill shank; the drill head is arranged in the slotted hole of the drill shank in a sleeved mode; the wall of the slotted hole is provided with an inverted-L-shaped sliding groove corresponding to the slotted hole; and a safety cover is arranged under the bolt. According to the drill bit convenient to disassemble and assemble, the drill head on the drill shank is convenient to replace, and the drill shank can be used in cooperation with various kinds of drill heads.
Description
Technical field
The present invention relates to cutting-tool engineering field, be specifically related to a kind of easy-to-mount drill bit.
Background technology
When tool sharpening, sometimes due to the different hole of machine-shaping size, it is necessary to the drill bit of various sizes, drill bit handle of a knife and cutter head may often be such that integrated, and when with tool changing head, handle of a knife also can with changing, and this will improve production cost.
Summary of the invention
For the problems referred to above, the present invention provides a kind of handle of a knife being easy to tool changing head, handle of a knife can close multiple cutter head with the use of easy-to-mount drill bit.
Realize technical scheme
Easy-to-mount drill bit, including handle of a knife and cutter head, cutter head is arranged on below handle of a knife, it it is cone bottom described cutter head, conical lower portion is provided with the arc groove holding chip removal, described cutter head is provided with some spiral cutting swords, the helical flute matched with cutting edge spiral it is provided with between each two cutting edge, cutting edge, helical flute are connected with arc groove, described cutter head is installed above bolt, offers slotted eye below handle of a knife, and tool bit casing is contained in handle of a knife slotted eye, offering the chute that inverted L-shaped is corresponding with slotted eye on slotted eye wall, bolt is arranged below protecting cap.
Horizontal cutting edge it is provided with in described chip area.
Adopt such scheme, owing to bottom cutter head being cone, bellmouth can be processed, conical lower portion is provided with the arc groove holding chip removal, improve chip removal ability, prevent Integrated Chip, described cutter head is provided with some spiral cutting swords, the helical flute matched with cutting edge spiral it is provided with between each two cutting edge, cutting edge, helical flute is connected with arc groove, improve chip removal ability, described cutter head is installed above bolt, slotted eye is offered below handle of a knife, tool bit casing is contained in handle of a knife slotted eye, slotted eye wall offers the chute that inverted L-shaped is corresponding with slotted eye, bolt is arranged below protecting cap, cutter head is placed in the slotted eye below handle of a knife, bolt is along L-shaped chute, bottom slideway L-shaped, rear rotation, it is installed on the afterbody of inverted L-shaped, tight a bolt again, cutter head and handle of a knife are linked together, inverted L-shaped chute can fix cutter head and handle of a knife in the axial direction, make the connection with the cutter head after changing and handle of a knife more firm.
By the detailed description below in conjunction with accompanying drawing, the present invention is aforesaid be will become clear from other purpose, feature and advantage.Wherein:
Fig. 1 is the structural representation of the present invention.
Fig. 2 is Knife handle structure schematic diagram of the present invention；
Fig. 3 is cutter head structure schematic diagram of the present invention
Wherein, 1 is handle of a knife, and 2 is cutter head, and 3 is arc groove, and 4 is spiral cutting sword, and 5 is bolt, and 6 is chute, and 7 is spiral cutting groove.
Detailed description of the invention
As shown in the figure, easy-to-mount drill bit, including handle of a knife 1 and cutter head 2, cutter head 2 is arranged on below handle of a knife 1, it it is cone bottom cutter head 2, bellmouth can be processed, conical lower portion is provided with the arc groove 3 holding chip removal, improve chip removal ability, prevent Integrated Chip, described cutter head 2 is provided with some spiral cutting swords 4, the helical flute 7 matched with cutting edge spiral it is provided with between each two cutting edge, improve chip removal ability, horizontal cutting edge it is provided with in described chip area, the chip removal of spiral is cut off, debris is prevented to be wound on cutter head, cutting edge, helical flute 7 is connected with arc groove 3, improve chip removal ability, described cutter head 2 is installed above bolt 5, slotted eye is offered below handle of a knife 1, cutter head 2 is sleeved in handle of a knife 1 slotted eye, slotted eye wall offers the inverted L-shaped chute corresponding with slotted eye 6, bolt 5 is arranged below protecting cap, cutter head 2 is placed in handle of a knife 1 slotted eye below, bolt 5 is along L-shaped chute 6, when sliding into bottom L-shaped, rear rotation, it is installed on the afterbody of inverted L-shaped, tight a bolt 5 again, cutter head 2 and handle of a knife 1 are linked together, inverted L-shaped chute 6 can fix cutter head and handle of a knife in the axial direction, make the connection with the cutter head 1 after changing and handle of a knife 2 more firm, protecting cap can protect handle of a knife 1 and the contact surface of cutter head 2.
The above, be only presently preferred embodiments of the present invention, the present invention not does any pro forma restriction, any simple modification that above example is made by every technical spirit according to the present invention, equivalent variations, each falls within protection scope of the present invention.
