Description
Technical field
The present invention relates to a kind of machining equipment, specifically a kind of for machining ball high-speed machine tool main shaft.
Background technology
In the prior art, ball high-speed machine tool main shaft complicated integral structure and loose, difficult processing and symmetry are poor, therefore operating accuracy is low, rotating speed is low, existing main shaft can not automatic tool changer on the other hand, needs people's hand operated, and this is with regard to waste of manpower and consume too many man-hour; General main shaft does not possess the function of inside and outside drifting dust, and the service life of equipment is short and security performance is low.
Summary of the invention
The invention provides a kind of single head double abrasive wheel electricity main shaft, it has overcome the deficiencies in the prior art
The technology of the present invention solution is that left end cap assembly (1) is arranged, bearing block assembly (2), left bearing assembly (3), cylinder block set (4), motor stator (5), right bearing assembly (6), include axle core main body (8.1), the axle core component (8) of copper cage rotor (8.2) and shaft shoulder cover (8.3), grinding wheel stand assembly (9), hex nut (10), it is characterized in that having grinding wheel stand assembly (9) to be fixed on the right part of axle core component (8), described grinding wheel stand assembly (9) includes the grinding wheel stand main body (9.1) of progressive step, the chopped-off head step of grinding wheel stand main body (9.1) is provided with little grinding wheel pressure plate (9.3), be fixed with little emery wheel between little grinding wheel pressure plate (9.3) and two stage steps protuberance, the two stage steps place of grinding wheel stand main body (9.1) is provided with large grinding wheel pressure plate (9.2), is fixed with large emery wheel between large grinding wheel pressure plate (9.2) and one-level step protuberance.
More than cylinder block set of the present invention (4) right-hand member be provided with right end cap assembly (7), described right end cap assembly (7) is comprised of the plug (7.3) of the air drain end that forms between the right end cap inner sleeve (7.2) of outer field right end cap overcoat (7.1), internal layer and the inside and outside cover.
Operation principle of the present invention: single head double abrasive wheel electricity main shaft is that integrated rolling bearing, cooling device, gas sealing system, motor-driven, emery wheel mount pad are in the device of the electromechanical integration of one; The inner conical surface of grinding wheel stand assembly cooperates assembling with the axle core component male cone (strobilus masculinus), locks to realize transmission of torque with hex nut, and small one and large one is installed in two emery wheels on the bearing block assembly, with the purpose that realizes that two emery wheels are worked simultaneously and processed simultaneously two workpiece.The main shaft Principle of Rotating: primary structure by: axle core component, bearing block assembly, left bearing assembly, cylinder block set, motor stator, right bearing assembly and external frequency converter etc. form.Axle core component is equipped with copper cage rotor, forms main shaft rotation main parts size with motor stator.Pass into three-phase alternating current to external frequency converter during work, the frequency conversion of frequency converter is 0-334Hz, and to the motor stator electric current, motor just rotates with 0-10000 rpm rotating speed by frequency converter; Body cool cycles principle: primary structure is comprised of left end cap assembly bearing holder assembly and cylinder block set, left end cap assembly, bearing block assembly and cylinder block set are having tank and water hole along circumference, during work, cooling water enters from the left end cap assembly, then having tank and water hole to flow along circumference along bearing block assembly and cylinder block set, again from the outflow of left end cap group, formation circulates at last, most of heat of motor and bearing generation is taken away, to motor and bearing cooling.The sealing gland principle: primary structure is comprised of left end cap assembly, right dust-proof cover, bearing block assembly and cylinder block set.During work, Compressed Gas enters from the left end cap assembly, enters right dust-proof cover by bearing block assembly, cylinder block set, flows out from the gap of dust cap and rotating shaft at last, and dust is got lodged in outside the dust cap, has prevented that effectively dust from entering bearing.
The invention has the advantages that:
1, utilizes external converter power supply, main shaft is rotated under the 0-10000rpm rotating speed, can satisfy the use of emery wheel under different rotating speeds;
2, main shaft inside is equipped with circulating cooling system, guarantees that motor and bearing work at low temperatures, can satisfy the work of main shaft long time stability;
3, main shaft inside is equipped with dust prevention system, utilizes the mode of sealing gland dustproof, guarantees that bearing is not contaminated, improves bearing service life;
4, bearing assembly adopts angular contact bearing, and pretightning force is arranged, and can bear axial force and radial load when making emery wheel work;
5, this structure adopts the mode of manually changing emery wheel;
6, this spindle vibration and noise are all very little, and rotating speed is steady;
7, rotor adopts the copper cage-shaped structure, and thermal losses is little, function admirable;
8, main shaft can be installed two emery wheels simultaneously, can process simultaneously two workpiece, and production efficiency and economic benefit are high.
