Technical field
The invention belongs to engineering machinery field, particularly to a kind of micro-blade motor.
Background technology
A very important job in the industries such as boring is geological prospecting, dig up mine, build, tunnel, such as
Anchor cable hole, blast hole, installing hole etc., especially geological prospecting sampling often require that and is deep into the deepest ground
Work in Ceng, high temperature resistant, the decay resistance of rig is required the highest.
At present, equipment and instrument for boring work have a lot, such as hydraulic drill rig, pneumatic drilling machine, punching
Hit churn and supporting various carbide drill, diamond drill first-class.These rigs be all
It is mounted directly drill bit on the output shaft of rig, or lengthening is then installed for drilling deep hole on the output shaft of rig
Drilling rod, is connected to the front end of drilling rod the most again by drill bit, owing to rig is to provide the equipment of power, and its volume
Relatively big, can only rest on outside bored hole, it is impossible to realize closely power supply, therefore its dynamic Control
Poor.
Sliding-vane motor is a kind of executive component of hydraulic system, and the fluid pressure that hydraulic pump provides can be changed by it
For the mechanical energy of its output shaft, the work that applies it to hole can overcome in current rig rig cannot
The defect of power is closely provided.But the most general sliding-vane motor but has the disadvantage that
1, rotating speed is low, generally 1500～1800 RPM, and can only use the slow-speed of revolution during drilling deep hole, therefore bores
Enter poor efficiency, during high rotating speed, it is impossible to drilling deep hole；
2, moment of torsion is big, volume is also big, a diameter of 100～150mm, and the force feed flow of needs is high, generally
18～21ml/rev, therefore need relevant hydraulic test to have the highest outfit, cost is high；
3, motor fuselage high temperature resistant, decay resistance is relatively low, there is certain limitation in range of application.
Summary of the invention
It is an object of the invention to for above technical problem, it is provided that a kind of flow is little, rotating speed is high, simple in construction
Compact, compact is light, low cost, the micro-blade motor of applied range.
The present invention be the technical scheme is that a kind of micro-blade motor for achieving the above object, including machine
Body, fuselage is made up of main shaft, stator, rotor, drive end bearing bracket, rear end cap, and in each groove of rotor, radial equipartition is even
Being connected to blade, rotor is connected in stator die cavity, and stator is between drive end bearing bracket, rear end cap, and main shaft is longitudinally
Run through drive end bearing bracket and rear end cap, it is characterised in that: stator die cavity and rotor die cavity are circle, stator die cavity
There is bias between center and rotor die cavity center, blade two ends are fluted, and connecting in groove has turn,
Each root of blade is slidably connected in rotor slot, and each vane tip is adjacent to stator type inner cavity surface, oil-feed
District, oil back region lay respectively at the both sides at stator die cavity center and the rotor die cavity line of centres.
Further, described stator shaft orientation both sides are connected to bearing, between bearing and stator two axial face
There is pad respectively, and the equal bolt of pad is connected on stator.
Further, described bearing is connected to ripple spring near the two ends of main shaft, connecting bushing on each ripple spring,
Each lining connects and has O.
Further, described main shaft is fixed by nut and drive end bearing bracket, rear end cap and is connected.
Further, described front-end of spindle connector is helicitic texture.
Further, described drive end bearing bracket is connected by screw is fixing with rear end cap, and drive end bearing bracket is fixedly connected with
Oil-in, oil-out, location first, location second.
The present invention changes traditional oval stator die cavity into circular design, and rotation flow is only 8～10ml/rev,
Eccentric center principle is utilized to make motor rotary speed scope bring up to 1000～3500 RPM, it is achieved low discharge, high rotating speed,
Thus reduce cost；Parts material of the present invention is the heat-resisting special steel of 4Cr9Si2 or 6542 high-speed steel, can
The hot environment of up to 170 DEG C normally works, and a diameter of 70～90mm, overall appearance is small and exquisite, with
Time rig can be installed spindle end is convenient, therefore can the most in depth descend very deep to work with rig,
Ensure that in-plant power supply, make work efficiency bring up to 90～92%, cannot only be applied to typically bore
In the work of hole, more can meet the demand of the special operation conditions such as such as geology, mine, oil field.

Embodiment
A kind of micro-blade motor as shown in Fig. 1～5, fuselage is by main shaft 1, stator 2, rotor 3, front end
Lid 4, rear end cap 5 form.Stator 2 die cavity and rotor 3 die cavity are circle, stator 2 die cavity center with turn
Son 3 die cavity centers between exist bias, oil-feed district 9, oil back region 10 lay respectively at stator 2 die cavity center with
The both sides of the rotor 3 die cavity line of centres；In each groove of rotor 3, radial equipartition connects blade 6,6 liang of each blade
Holding fluted 7, connecting in groove 7 has turn 8, makes each blade 6 root be slidably connected to rotor 3
In groove, each blade 6 top is adjacent to stator 2 die cavity inner surface；Rotor 3 is connected in stator 2 die cavity, fixed
Son 2 is between drive end bearing bracket 4, rear end cap 5, and the axial both sides of stator 2 are connected to bearing 11, bearing
Having pad 12 bolt to be connected on stator 2 respectively between 11 and 2 liang of axial faces of stator, bearing 11 is close
Spindle end is connected to ripple spring 13, connecting bushing 14 on each ripple spring 13, connects and have O type in each lining 14
Circle 15；Main shaft 1 front end connector is helicitic texture, can conveniently connect the boring instruments such as drill bit, main shaft 1
Longitudinally through drive end bearing bracket 4 and rear end cap 5, main shaft 1 is fixed with drive end bearing bracket 4, rear end cap 5 by nut 16
Connect；Oil-in 18, oil-out 19, oil-in 18, oil-out 19 points it is fixedly connected with on drive end bearing bracket 4
Not corresponding connection oil-feed district 9, oil back region 10, drive end bearing bracket 4 is fixedly connected with location first 20, location second 21,
The devices such as drill bit can be fixedly connected on micro-blade motor by location first 20, location second 21, front end
Lid 4 is connected by screw 17 is fixing with rear end cap 5.
The operation principle of the present invention:
As it is shown in figure 1, by blade 6-1 clockwise to blade 6-5 be oil-feed district 9, clockwise by blade 6-6
It is oil back region 10 to blade 6-10.Owing to the die cavity center of stator 2 exists bias with the die cavity center of rotor 3,
And the top of each blade 6 is adjacent to the die cavity inner surface of stator 2, therefore at oil-feed district 9 Leaf 6-1 to blade
The die cavity that the die cavity inner surface of the most adjacent two blades between 6-5 and stator 2, rotor 3 are formed incrementally increases,
Corresponding the most adjacent two blades between oil back region 10 Leaf 6-6 to blade 6-10 and the die cavity of stator 2
The die cavity that inner surface, rotor 3 are formed progressively reduces.Under the effect of pressure oil, by leaf in oil-feed district 9
Sheet 6-1 is gradually increased to blade 6-5 stress, and blade 6-6 is gradually reduced to blade 6-10 stress, thus ensures
Each blade 6 on rotor 3 turns clockwise；The root of each blade of reason 6 is slidably connected to rotor 3 again
In groove, therefore blade 6-1 is the most protruding to blade 6-5 when starting to rotate, blade 6-6 to blade 6-10
All it is inwardly indented, thus moves in circles, thus ensure that the circulation rotating of each blade 6 on rotor 3.
The work process of the present invention:
During work, sampling drill bit is installed on the front end of micro-blade motor spindle 1, and by location first
20, location second 21 is fixed, and is connected with motor, hydraulic pump by high-pressure oil pipe by micro-blade motor, checks
