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 is poor, therefore operating accuracy is low, rotating speed is low, on the other hand existing main shaft can not automatic tool changer, 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-end double-grinding-wheeelectric electric spindle, which overcome the deficiencies in the prior art
The technology of the present invention solution has left end cap assemblies (1), 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), little emery wheel is fixed with 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), large emery wheel is fixed with between large grinding wheel pressure plate (9.2) and one-level step protuberance.
Cylinder block set of the present invention (4) right-hand member is provided with right end cap assembly (7) above, and described right end cap assembly (7) is made up of the plug (7.3) of the air drain end formed between the right end cap inner sleeve (7.2) of outer field right end cap overcoat (7.1), internal layer and inside and outside cover.
Operation principle of the present invention: Single-end double-grinding-wheeelectric electric spindle is that integrated rolling bearing, cooling device, gas sealing system, motor driving, emery wheel mount pad are in the device of the electromechanical integration of one; The inner conical surface of grinding wheel stand assembly coordinates with axle core component male cone (strobilus masculinus) and assembles, with hex nut locking to realize transmission of torque, two emery wheels small one and large one be arranged on bearing block assembly, work and the object of simultaneously processing two workpiece to realize two emery wheels simultaneously.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 rotate 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 by frequency converter to motor stator electric current, motor just rotates with 0-10000 rpm rotating speed; Body cool cycles principle: primary structure is made up of left end cap assemblies bearing block assembly and cylinder block set, left end cap assemblies, bearing block assembly and cylinder block set have tank and water hole on circumferentially, during work, cooling water enters from left end cap assemblies, then on circumferentially, have tank and water hole flowing along bearing block assembly and cylinder block set, finally flow out from left end cap group again, formation circulates, most of heat that motor and bearing produce is taken away, to motor and bearing cooling.Sealing gland principle: primary structure is made up of left end cap assemblies, right dust-proof cover, bearing block assembly and cylinder block set.During work, Compressed Gas enters from left end cap assemblies, enters right dust-proof cover by bearing block assembly, cylinder block set, finally flows out from the gap of dust cap and rotating shaft, is got lodged in by dust outside dust cap, effectively prevent dust and enter bearing.
The invention has the advantages that:
1, utilize external converter power supply, main shaft is rotated under 0-10000rpm rotating speed, the use of emery wheel under different rotating speeds can be met;
2, main shaft inside is equipped with circulating cooling system, guarantees that motor and bearing work at low temperatures, can meet the work of main shaft long time stability;
3, main shaft inside is equipped with dust prevention system, utilizes the mode of sealing gland dust-proof, guarantees that bearing is not contaminated, improves bearing service life;
4, bearing assembly adopts angular contact bearing, and has pretightning force, makes can bear axial force and radial load during stone;
5, this structure adopts the mode manually changing emery wheel;
6, this spindle vibration and noise are all very little, and rotating speed is steady;
7, rotor adopts copper cage-shaped structure, and thermal losses is little, function admirable;
8, main shaft can install two emery wheels simultaneously, can process two workpiece, production efficiency and high financial profit simultaneously.
