Abstract
The utility model relates to a numerical control machine tool, in particular to a fixed connection mechanism between a spindle and a rotor of an electric spindle unit of a numerical control machine tool. The utility model solves the technical problem that the spindle of the machine tool has to be discarded since the spindle is unlikely to be separated from a rotor that needs to be replaced due to improper heat introduction or damage. The connection structure between the spindle of the machine tool and the motor comprises the spindle and rotors of the machine tool, and a shaft sleeve fixedly connected with the outer side of the spindle through keys, wherein the rotors are fixed outside the shaft sleeve.
Description
Technical field
The utility model relates to Digit Control Machine Tool, particularly the fixed connection structure between the rotor of the machine tool chief axis of electric main shaft of digital control machine tool unit and motor.
Background technology
The electric main shaft of Digit Control Machine Tool produces magnetic field force by rotor and stator by electric current, and the main spindle box that is fixed on epitrochanterian machine tool chief axis and is fixed on the stator is produced relative rotation by bearings.Fixing between existing rotor and the machine tool chief axis gone into machine tool chief axis cooling back formation interference fit by rotor heat and realized, if it is not in place that rotor heat is gone into, or rotor damages and to need to change, or main shaft bearing was when losing efficacy, machine tool chief axis can't separate with rotor, causes machine tool chief axis also to be scrapped.Because the manufacturing cost of machine tool chief axis is higher,, just can save assembling and maintenance cost greatly if can avoid a series of parts such as machine tool chief axis and main shaft bearing to be scrapped by related.
The utility model content
The purpose of this utility model is to solve rotor heat to go into not in placely, or rotor damages and need to change, or main shaft bearing was when losing efficacy, and a series of parts such as machine tool chief axis and main shaft bearing are because of separating the technical problem that quilt is scrapped with rotor.
The syndeton of machine tool chief axis and motor comprises machine tool chief axis and rotor, is provided with by key and is fastened on the outer axle sleeve of machine tool chief axis, and described rotor is fixed on outside the axle sleeve.
Owing between machine tool chief axis and rotor, be provided with axle sleeve, go into not in place or rotor damages when needing to change when rotor heat, only need to remove key and connect and can allow rotor and axle sleeve separate with machine tool chief axis.So only need scrap rotor and axle sleeve, just can preserve machine tool chief axis and continue to use, save assembling and maintenance cost greatly.
Description of drawings
Fig. 1 is a cutaway view of the present utility model.
The specific embodiment
As Fig. 1, in the Digit Control Machine Tool, the syndeton of machine tool chief axis and motor comprises machine tool chief axis 1 and rotor 3, is provided with by key 2 and is fastened on machine tool chief axis 1 axle sleeve 4 outward, and described rotor 3 is fixed on outside the axle sleeve 4.
Claims (1)
1. the syndeton of machine tool chief axis and motor comprises machine tool chief axis (1) and rotor (3), it is characterized in that, is provided with by key (2) and is fastened on the outer axle sleeve (4) of machine tool chief axis (1), and described rotor (3) is fixed on outside the axle sleeve (4).
