Abstract
The utility model relates to a drill head, a cutter body and a cutting edge of which can be dismantled. An axle core which is arranged at the drilling rod to the cutter body end is through the cooling liquid tube. The cutter body and the drilling rod are connected by the sheathed nut. The connected end of the cutter body and the drilling rod uses the flat key cuttage grafting to transmit the torque force. The cutting edge has the coarse edge and the fine edge. The designed drill head can enlarge the application range of the hole diameter of the drill press boring and can bore the deep hole.
Description
The utility model belongs to the drill bit that the boring drilling machine uses, especially for boring wide-aperture deep hole.
Existing drill bit all is whole.In order to go out bits, helicla flute is arranged on drilling rod.Helicla flute is used for to blade and injects cooling fluid.There is following shortcoming in this solid drill: want frequent sharpening when at first using, influence efficient.Secondly flute easily stops up, and cooling fluid is difficult for entering blade part.Another shortcoming, blade and knife bar are generally thick, bore the large aperture, and drill bit is very heavy.
The purpose of this utility model provides a kind of new construction drill bit that overcomes above-mentioned shortcoming, makes the drill bit convenient disassembly, easily goes out bits, good cooling results.Another purpose of the present utility model is the boring aperture scope that enlarges little drilling machine.
Content of the present utility model is that solid drill is designed to drill bit by drilling rod, cutter hub and the combination of thick, smart blade, and at the axle core of drilling rod and cutter hub the coolant pipe that communicates is arranged.
The design's a part is that drill bit is made dismantled and assembled drill bit by thick, smart blade, cutter hub and drilling rod assembly.Another part of the present utility model is to connect in the axle core position of drill bit to bore thick stick and drill bit has a coolant pipe.The design's characteristics be blade blunt can change blade, and needn't change drill bit integral body.Can the tool changing body when boring the hole in different apertures and blade and need not change drilling rod.High efficiency not only can also enlarge the scope of application of drilling machine.Another advantage of the design is that interior cooling tube is arranged, the cooling effectiveness height, and not hindered by smear metal, also help chip removal.
The design's a embodiment as shown in drawings.
Coolant pipe 1, blade briquetting 2a, housing pin 2b, blade 3a, 3b, wherein blade 3a is smart sword, blade 3b is a coarse tooth, cutter hub 4, blade groove 5, cover connected nut 6, cover connected nut cannelure 7a, cover connected nut cannelure open-work 8a open-work jackscrew 8b, drilling rod cannelure 7b, drilling rod 9, the external tube head 10 of coolant pipe, cooling fluid transfusion sleeve pipe 11, drilling rod infusion hole 12.
Design further specifies to the utility model in conjunction with the embodiments:
The design comprises detachable cutter hub, detachable blade, drilling rod and cooling system.
Detachable cutter hub is made up of cutter hub 4, cover connected nut 6 and drilling rod 9.Cover connected nut 6 internal diameters one end has the spiral screw thread, and the other end has cannelure 7a, and the open-work 8a of break-through nut wall is arranged on the cannelure.Open-work directly is equal to or slightly less than the cannelure internal diameter, and the open-work internal diameter has screw thread, can adorn jackscrew 8b.The cutter hub union end has screw thread, spins with the cover connected nut, and drilling rod union end external diameter has and the corresponding cannelure 7b of cover connected nut internal diameter cannelure.Drilling rod is pegged graft after the cover connected nut, and two cannelures form the circular passage relatively, is equal to or slightly less than the steel ball of circular passage with external diameter, puts into cannelure 7a7b through open-work 8a and pins drilling rod 9 and cover connected nut 6, shuts open-work 8a with jackscrew 8b then.Drilling rod 9 adopts flat key to peg graft with the union end of cutter hub 4.The effect of the screw thread on this connecting mode cutter hub and the cover nut is connection and regulates two cannelure contrapositions, does not transmit the drilling rod rotary torsion, has the characteristics of convenient disassembly.
The mode that the detachable blade of present embodiment adopts blade 3 to connect with cutter hub 4 usefulness briquettings 2.The blade groove 5 of cutter hub end is
Shape, wide outside and narrow inside, at trench bottom screw is arranged, briquetting 2 is a wedge shape.Corresponding blade trench bottom screw has the housing screw perforation on the briquetting.Screwing briquetting 2 just can squeeze blade 3 among blade groove 5.The blade of the utility model design has two kinds: a kind of is coarse tooth 3b, and a kind of is smart sword 3a.In with coolant pipe 1 being two blade grooves 5 on boundary, cutter hub respectively puts one piece of coarse tooth, smart sword.Cutter hub rotates a circle can be slightly, essence is respectively cut a week.This mode can improve drilling efficiency.
The design's cooling system is by coolant pipe 1, infusion hole 12, and transfusion sleeve pipe 11, coupling 10 is formed.Coolant pipe 1 connects the end of drilling rod 1 to cutter hub 4.Infusion hole 12 is arranged on drilling rod, have on the position of infusion hole 12 can external coolant pipe joint 10 transfusion sleeve pipe 11.Drilling rod 9 can rotate in sleeve pipe 11, and sleeve pipe 11 two ends contact with the sealing of drilling rod wall.Cooling fluid is in joint 10 enters gap between sleeve pipe 11 and the drilling rod 9, and the infusion hole 12 on the drilling rod 9 is with drilling rod 9 rotations, and the cooling fluid in the gap of drilling rod 9 and sleeve pipe 11 directly enters the cutter hub end in infusion hole 12 enters coolant pipe 1 in the drilling rod.
The design of present embodiment can make the cutter hub in various apertures and the drilling rod of blade and brill different depth according to actual needs.
