Description
Technical field
The utility model relates to a kind of technology in linear motor field, specifically a kind of straight driving transmission mechanism.
Background technique
Traditional servo motor ball-screw mould group, what accumulated error and ball-screw with each machine components moved back and forth
Back clearance error, therefore repetitive positioning accuracy and positioning accuracy are poor.In addition, ball-screw mould group is not suitable for more mover movements, by
It is limited in the processing technology of ball-screw, be also not suitable for the movement of ultralong-stroke, and linear motor mould group can meet high-precision,
At a high speed, the movement occasion of ultralong-stroke.With the continuous development of technology, linear motor mould group will replace ball-screw mould group,
But most of linear motor mould groups, cross-sectional width is larger, occupies that installation space is big, uncomfortable for the occasion for replacing KK mould group
It closes.
Utility model content
The utility model In view of the above shortcomings of the prior art, proposes a kind of straight driving transmission mechanism, using straight line
The movement of high-precision, high speed, ultralong-stroke may be implemented in the technology of motor direct-drive, while can eliminate traditional servo electricity
Machine ball-screw mould group because intermediate transmission component it is more caused by the back clearance error that moves back and forth of accumulated error and ball-screw,
While meeting requirements for high precision, guarantees that cross-sectional width is identical as tradition KK mould group, be conducive to be replaced KK mould group.
The utility model is achieved through the following technical solutions:
The utility model includes pedestal, pedestal is equipped with stator permanent magnet and guide rail, and guide rail is equipped with to be moved along guide rail
Slide is fixed with mover coil component on slide, and stator permanent magnet and mover coil component are corresponding, are equipped with air gap between the two；
Corresponding rails, the straight driving transmission mechanism are equipped with magnetic railings ruler parallel with it, and slide corresponds to magnetic railings ruler and is equipped with reading
Head.
The guide rail both ends are equipped with hard limit base, and the hard limit base is equipped with limited block.
The guide rail and the ipsilateral setting of magnetic railings ruler are arranged with stator permanent magnet heteropleural.
The slide uses L-type structure, and reading head and mover coil component are each attached on slide.
The pedestal is processed using High-strength aluminum product or is process using aluminium extruded section, and lower mode can be inhibited
Harmony response amplitude, while overcoming the vibration of high order mode, make it have good dynamic response characteristic.
Technical effect
Compared with prior art, the utility model uses the technology of linear motor direct drive, and it is (fixed that high-precision may be implemented
Position and repetitive positioning accuracy reach micron level), high speed (4m/s), ultralong-stroke (4m or more) movement；The utility model can
With eliminate traditional servo motor ball-screw mould group because intermediate transmission component it is more caused by accumulated error and ball-screw it is reciprocal
The back clearance error of movement, avoids that ultralong-stroke screw rod is rigidly weak, the slow influence of the speed of service caused by flexible difference, greatly reduces
The working strength and difficulty of cost and installation and debugging；While meeting requirements for high precision, guarantee cross-sectional width and tradition KK
Mould group is identical, is conducive to be replaced KK mould group.
