Description
Technical field
The utility model belongs to Computerized Numerical Control processing technology field, particularly a kind of closed-loop control servo-drive electro spindle with deceleration device.
Background technology
Existing middle-size and small-size numerical control machining center electro spindle is primarily of compositions such as axle, rotor, stator, bearing and cooling systems, adopt ac variable frequency speed regulation and vector controlled, rotating speed is relatively high, but due to output torque less, be restricted at low speed high torque manufacture field; And because motor self is without controlled torque, in operation process, accurately can not control rotation and the start and stop position of main shaft, processing when cutter rotates during processing work, can only be realized, particular tool orientation cannot be realized and determine angle processing, processing blind area is existed for wedge angle.Although the electro spindle of some machining center has installed code-disc and encoder, can realize quick standard and stop, can not realize the closed-loop control of the axle anglec of rotation, the angle precision of axle is poor, cannot meet high accuracy processing request.In addition, because axle outer setting has the structures such as stators and rotators, not only complex structure, and also can produce amount of heat during running, cause electro spindle temperature rise, affect electro spindle performance, although the temperature rise of part main shaft can be reduced by increasing cooling provision, but also make electric main shaft structure more complicated, and considerably increase the manufacturing and the use cost of electro spindle.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of structure simple, convenient processing and manufacture, the closed-loop control servo-drive electro spindle that cost is low, comparatively high pulling torque can not only be realized export, meet the process requirements of low speed high torque, and high-precision Angle ambiguity can be realized, meet high accuracy processing request, effectively can also solve due to rotor heating and affect the problems such as electro spindle performance.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of closed-loop control servo-drive electro spindle with deceleration device, be made up of axle, block bearing, servomotor, reductor, angle feed-back encoder, encoder count head and sleeve, axle for mounting cutter is positioned at sleeve inner, and is connected with servomotor by reductor; Axle two ends are respectively equipped with block bearing; Axle is provided with angle feed-back encoder, and the correspondence position of sleeve is provided with encoder count head.
Above-mentioned a kind of closed-loop control servo-drive electro spindle with deceleration device, is connected by shaft coupling between described axle and the output shaft of reductor.
Above-mentioned a kind of closed-loop control servo-drive electro spindle with deceleration device, described block bearing is angular contact ball bearing.
Above-mentioned a kind of closed-loop control servo-drive electro spindle with deceleration device, described angular contact ball bearing is respectively two in the quantity at axle two ends.
Compared with prior art, the beneficial effects of the utility model are:
1. the utility model structure is simple, convenient processing and manufacture, and cost is low;
2. by installing reductor additional, high pulling torque output being achieved to servomotor deceleration, meeting the process requirements of low speed high torque;
3. by installing the closed-loop control that angle feed-back encoder realizes the axle anglec of rotation additional at output, accurately can control rotation and the start and stop position of main shaft, particular tool orientation can be completed and determine angle processing;
4. four angular contact ball bearings at axle two ends, can provide larger axial constraint power for axle, reduce heart shaft run-out, improve its rigidity, ensure the high-precision requirement of main shaft;
5. mandrel outer is without stator and rotor sructure, in servo-drive process, can not cause main shaft temperature rise, be conducive to keeping electro spindle performance due to rotor heating.
