Abstract
The utility model relates to an air floatation high-speed motorized spindle core component, in particular to a spindle core for a high-precision high-speed air floatation motorized spindle. A progressive stepped push rod (3) is disposed in an inner cavity of a spindle core body (1). A plastic slide sleeve (4) is sleeved on the middle step of the push rod (3). The spindle core body (1) is provided with a front flying disc. The air floatation high-speed motorized spindle core component is efficient, stable in operation, good in acceleration adaptation, low in temperature rise, high in power, more suitable for high-speed rotation, and convenient to popularize and use.
Description
Technical field
The utility model relates to a kind of machining equipment, specifically a kind of axle core for high-precision high-speed air supporting electricity main shaft.
Background technology
In the prior art, general air floated high speed electric mandrel adopts the copper cage-shaped structure to make rotor, and its efficient is low, move not too steadily, accelerates bad adaptability, and temperature rise is big, and power is little, not too is fit to rotate at a high speed.
Summary of the invention
The utility model relates to a kind of air floated high speed electric mandrel axle core component, and it has solved the deficiencies in the prior art.
The utility model technical solution is to comprise a core main body (1), copper squirrel-cage bar and end ring (2), disk spring (5), locking nut (6), chuck (7), cutter (8) is characterized in that core main body (a 1) inner chamber is provided with the axle despot (3) of progressive step, be with plastics sliding sleeve (4) in axle despot (3) middle bench portion, axle core main body (1) is provided with preceding flying disc.
Operation principle of the present utility model is a despot, locking nut and chuck screw-threaded coupling, and the axle despot can slide at the axle in-core, and disk spring produces chucking power, and chuck is by the chucking power clamp-on tool.The taper hole of axle core and the male cone (strobilus masculinus) of chuck are fitted, and when the axle despot slided up and down, chuck was under the effect of male cone (strobilus masculinus), and endoporus swells or dwindles, and produce the process of folder cutter or loose cutter thus.Be embedded with copper squirrel-cage bar and end ring above the axle core.During work, axle is seized by force under external force, to lower slider, and the compression of dish spring, chuck moves down thereupon, and chuck is under elastic reaction, and endoporus opens, and cutter comes off, and finishes the cutter process of unloading; This moment can be to logical compressed air in the axle despot, drifting dust; And then mounting cutter, removing external force, chuck clamps under the effect of disk spring, finishes dress cutter process, and axle core component fitted bearing and motor stator can be realized the high speed rotation of 0-100000rpm simultaneously.
Advantage of the present utility model is:
1, axle core component is by external force, the conveniently assemble and disassemble cutter;
2, on the axle despot plastics sliding sleeve is arranged, the coefficient of sliding friction is little, and the life-span is long;
3, the axle core is seized by force with axle plastics sliding sleeve quality of fit height, and it is accurate that the axle despot moves back and forth the position;
4, axle core component cooperates with motor stator, can realize the 0-100000rpm rotation;
5, the axle core has preceding flying disc, can realize the high-speed smooth rotation, and can bear bigger axial force;
6, the high speed dynamic property of axle core is good, and precision is good, and advantages such as long service life can be widely used in the axle core of various air supportings electricity main shafts.
Description of drawings
Fig. 1 is profile construction schematic diagram of the present utility model.
The specific embodiment
According to shown in Figure 1, the utility model is in existing axle core main body (1), copper squirrel-cage bar and end ring (2), disk spring (5), locking nut (6), chuck (7), on the basis of cutter (8), axle core main body (1) inner chamber is provided with the axle despot (3) of progressive step, is with plastics sliding sleeve (4) in axle despot (3) middle bench portion, and axle core main body (1) is provided with preceding flying disc.
Claims (1)
1. air floated high speed electric mandrel axle core component, it comprises a core main body (1), copper squirrel-cage bar and end ring (2), disk spring (5), locking nut (6), chuck (7), cutter (8), it is characterized in that core main body (a 1) inner chamber is provided with the axle despot (3) of progressive step, be with plastics sliding sleeve (4) in axle despot (3) middle bench portion, axle core main body (1) is provided with preceding flying disc.
