Description
Technical field
The present invention relates to mechanical fitting technical field, is specially that one kind is used for mine working drill bit and axis connection knot
Structure.
Background technology
Drill bit be on solid material drilling go out through hole or blind hole, and can be to the cutter of existing hole reaming.It is conventional
Drill bit mainly have fluted drill, chit drill, centre drill, depth drill and cylindrical drill.Drill bit is to fractured rock, shape in drilling engineering
Into the rock crushing tool of pit shaft.The efficiency of breaking rock and service life of drill bit directly affect the service index and performance of drill bit.Axis connection
Structure is the auxiliary accessories for drill bit and peripheral hardware rig are attached, and is easy to the development to underground excacation.
Fluted drill is most widely used hole process tool.General diameter scope is 0.25~80 millimeter.Its groundwork
Part and shank are formed.Working portion has two spiral grooves, is similar to fried dough twist, thus gains the name.Led during in order to reduce drilling
Friction between part and hole wall, is in inverted cone shape that fluted drill, which is gradually reduced diameter from apex point to shank direction,.The spiral of fluted drill
Angle mainly influences the size of anterior angle on cutting edge, sword valve intensity and chip removal performance, usually 25 °~32 °.Spiral groove can use
The methods of milling, grinding, hot rolling or hot extrusion, processes, and the front end of drill bit forms cutting tip after sharpening.The cutting portion of chit drill
It is divided into spade, simple in construction, manufacturing cost is low, and cutting fluid is easily in entrance hole, but cut and chip removal poor-performing.The knot of chit drill
Structure has two kinds of monoblock type and assembled.Depth drill typically refers to process the cutter in the hole of the ratio between hole depth and aperture more than six.It is conventional
Have drill gun, BTA depth drills, jet drilling, DF depth drills etc..Cylindrical drill is also commonly used for deep hole machining.Hollow boring bit is called coring
Drill bit, magnetic force drill bit, magnetic support drill bit, hole making drill.After drill bit two-edged milled, a plane is had at two-edged sharp point, is influenceed
The centralized positioning of drill bit is as far as possible ground the plane in blade tip portion small, it is necessary to fall an inferior horn behind sword.Method is to hold up drill bit,
The angle of emery wheel is directed at, the root behind sword, a sulculus is fallen against blade tip.This is also bit centering and cuts brisk weight
Want a bit.It when paying attention to repairing sharpening point chamfering, must not be ground on main cutting edge, can so make the anterior angle of main cutting edge inclined
Greatly, drilling is directly affected.
At present, the output axis connection of drill bit and rig is mainly connected using flange, and passes through bolt, screw or logical
Cross pin connection.But use and connected with upper type, after drill bit is fixed with rig, dismounting is inconvenient, takes time and effort, and the effect that drills
Fruit is undesirable, increases the burden of staff.
The content of the invention
In view of the shortcomings of the prior art, the invention provides one kind to be used for mine working drill bit and Axile connection structure,
The problem of solving drill bit and after rig fixation, dismounting be inconvenient, takes time and effort, and drilling effect is undesirable.
To realize object above, the present invention is achieved by the following technical programs：One kind is used for mine working drill bit
And Axile connection structure, including the first drill bit, one end of first drill bit be fixedly connected with the second drill bit, second drill bit
One end be fixedly connected with the 3rd drill bit, the other end of first drill bit offers the first groove and the second groove respectively, and
First groove and the second groove are connected, and sliding block, and the inwall of the first groove are symmetrically arranged with the inwall of first groove
Both sides are symmetrically arranged with two locating pieces, and the side of two locating pieces is fixedly connected with back-moving spring, the back-moving spring
Remotely located piece one end is fixedly connected with the side of sliding block, the side of the sliding block and is fixedly connected between locating piece
Locating rod, one end of second groove is interspersed to be provided with push rod, and one end of the push rod is fixedly connected with heading, and head a ball and
Shoe contact, the other end of the push rod are fixedly connected with top plate, are socketed with sleeve on the outside of the other end of first drill bit, institute
The inwall both sides for stating sleeve symmetrically open up fluted, and the one end of the sleeve away from the first drill bit is fixedly connected with locating shaft, and
And the one end of sleeve away from the first drill bit is inlaid with nut, screw rod is threaded with the nut, and one end of screw rod is fixed
It is connected with a side contacts of ball, the ball and top plate.
Preferably, first drill upper ring cuts sword around offering first, and first cuts sword laterally setting.
Preferably, second drill upper ring cuts sword around offering second, and second cuts sword and be obliquely installed, and angle of inclination is
45 degree.
Preferably, the 3rd is offered on the 3rd drill bit and cuts sword, and one end of the 3rd drill bit is provided with diamond.
Preferably, the inwall sliding contact of the sliding block and the first groove.
Preferably, the sliding block is arranged to arc with the position contacted of heading a ball.
Preferably, it is fixedly connected with limited block on the outside of the other end of first drill bit and positioned at one end of sleeve.
Preferably, the locating shaft is fixedly connected with the rig output shaft of peripheral hardware.
Preferably, when the sleeve contacts with limited block, now groove aligns setting with locating rod.
Preferably, during another end in contact of the top plate and the first drill bit, now heading is located at the perpendicular bisector of sliding block, and
And locating rod is extended in groove.
The invention provides one kind to be used for mine working drill bit and Axile connection structure.Possesses following beneficial effect：
（1）, this be used for mine working drill bit and Axile connection structure, using the first drill bit, the second drill bit, the 3rd drill bit knot
Structure is designed, and sword is cut to first on the first drill bit, second on the second drill bit sword is cut, the on the 3rd drill bit the 3rd cuts sword
Set, improve the efficiency of drilling, facilitate the development to underground excacation, improve operating efficiency.
（2）, this be used for mine working drill bit and Axile connection structure, by the first groove, the second groove, sliding block,
