Abstract
The utility model discloses an electric spindle of a numerical control machine. The electric spindle comprises a spindle (2) and an electric motor which are arranged in a box body (1), wherein the electric motor comprises a casing (3) and a rotor (4), and the rotor (4) is sleeved in the spindle (2) and positioned at the middle part of the spindle (1). The electric spindle is characterized in that the rotor (4) is connected with the spindle (2) through a tensioning device, and has the advantages of compact structure, little shake, and high rotate speed.
Description
Technical field
The utility model relates to a kind of electrical spindle for machine tool, particularly a kind of electric main shaft of digital control machine tool.
Background technology
At present, common Digit Control Machine Tool comprises main shaft and motor on the market, and motor is given main shaft by belt transmission or gear drive with the transmission of power of motor, makes main axis rotation, and there is following problem in such structure: the one, and vibrations are big, are unfavorable for Precision Machining; The 2nd, in the power transmission process loss bigger, make the rotating speed maximum of its main shaft be generally 2000 rev/mins-3000 rev/mins; The 3rd, the transmission mechanism complexity, cost is than higher.In order to solve the above problems, a lot of producers with motor directly and main shaft link together, as in CN201076995Y, disclosing the utility model patent that a kind of name is called " the electric mainshaft mechanism of lathe ", this patent relates to lathe, a kind of electric main axle structure of lathe particularly, the rotor of drive shaft motor rotating directly is packed on the main shaft, the housing of motor is fixedlyed connected with stator, and be installed on the frame, motor adopts the variable-frequency motor of frequency-variable controller control, and the housing of motor is shaped on the revolution cooling-water duct.This utility model directly is solidly set on the rotor of main motor on the main shaft, and main shaft is motor shaft, the transmission efficiency height, and dynamic response is fast, has omitted a whole set of mechanical driving device, mechanism's compactness.Because in this patent, rotor directly is solidly set on the main shaft, adopt interference fit to realize between them, when needs dismounting main shaft keeps in repair, the main shaft dismounting will sustain damage, simultaneously, because interference fit can not be changed bearing, after the damage of bearings of main shaft, main shaft just can only do to scrap processing.
The utility model content
The purpose of this utility model just provides a kind of electric main shaft of digital control machine tool of convenient for maintaining.
The purpose of this utility model is to realize by such technical scheme, a kind of electric main shaft of digital control machine tool, it comprises main shaft and motor, motor comprises housing and rotor, rotor is inserted in the main shaft and is positioned at the middle part of main shaft, it is characterized in that rotor is connected with main shaft by swelling device.
Swelling device comprises the spacer that is arranged between rotor and the main shaft, is provided with expansion set at the two ends of spacer, and expansion set is pressed in the slit between spacer and the main shaft, in the arranged outside of expansion set locking nut is arranged, and locking nut compresses expansion set by pressing spacer ring.
Motor and main shaft heat radiation in order to give rotation at a high speed are provided with the circulation water channel in housing.The circulation water channel is S-type to be horizontally installed in the housing, and the water inlet and the delivery port of described circulation water channel all are arranged on the casing.
Compared with prior art, the utlity model has the advantage of mechanism's compactness, simultaneously, because the power of motor is directly passed to main shaft, make that the main axis rotation vibrations are little, be beneficial to Precision Machining, but also make that the rotating speed of main shaft is fast, maximum can reach 6000 rev/mins; Wherein the swelling device that adopts has made things convenient for the assembling and the dismounting of main shaft; avoided the inconvenience of whole heating assembling in assembling process; improve the effect of spindle mounted, protected main shaft in assembling and dismounting, not sustain damage simultaneously, reduced manufacturing cost and use cost.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment: as shown in Figure 1, a kind of electric main shaft of digital control machine tool comprises the main shaft 2 and the motor that are arranged in the casing 1, and motor comprises housing 3 and rotor 4, and rotor 4 is inserted in the main shaft 2 and is positioned at the middle part of main shaft 1, and rotor 4 is connected with main shaft 2 by swelling device.
Swelling device in this example comprises the spacer 5 that is arranged between rotor 4 and the main shaft 2, be provided with expansion set 6 at the two ends of spacer 5, above-mentioned expansion set 6 is pressed in the slit between spacer 5 and the main shaft 2, in the arranged outside of expansion set 6 locking nut 7 is arranged, and above-mentioned locking nut 7 compresses expansion set 6 by pressing spacer ring 8.
In housing 3, be provided with circulation water channel 9, above-mentioned circulation water channel 9 S-type being horizontally installed in the housing 3, the water inlet 10 and the delivery port 11 of above-mentioned circulation water channel 9 all are arranged on the casing 1.Cooling water constantly circulates in the circulation water channel, rotates the heat that is given out at a high speed with motor and main shaft and carries out heat exchange, has reduced the temperature of motor and main shaft, has prolonged service life.
