Description
Technical field
The invention belongs to techniques of linear motor fields, and in particular to a kind of linear motor single shaft mould group.
Background technique
With the development of industrial automation, accuracy and speed requirement of the industries such as attachment, dispensing, radium-shine, medical to equipment
It being continuously improved, traditional screw rod carries the moving cell of servo motor, it has been unable to satisfy its demand, and a kind of novel carrying is straight
The motion platform of line motor has progressed into and has captured automation market.
Linear motor platform common at present has uniaxial, cross and gantry etc., uses cored linear motor and iron-free more
Core linear motor, the performance of this two motor difference, therefore the speed of its motion platform, quiet dynamic accuracy are also different.So
The quality of gantry platform property is the major criterion evaluated company's design, technique, a machine and the level such as add.Cored straight-line electric
Machine is big compared with ironless linear motors thrust density, but is influenced by Slot force, and in low speed operation, velocity perturbation is larger, and normal direction is inhaled
Power easily leads to malformation, therefore gantry platform for carrying cored linear motor does the movement of high speed point more, apply attachment,
The industries such as dispensing.And ironless linear motors gantry platform is applied to that rate request is lower, the detection, radium-shine that requires track to move
Etc. industries.
Summary of the invention

Column, crossbeam spindle motor mould group includes crossbeam, and column and crossbeam are cast member, the stator rabbet on column and crossbeam by
Machine tooling molding.
Further, the stator rabbet of column is two sides molding, and the two sides of double stators for driving spindle motor mould group is equipped with dynamic
Son.
Further, the stator rabbet of crossbeam is two sides molding, and the two sides of the stator of crossbeam spindle motor mould group is equipped with dynamic
Son.
Further, double drive spindle motor mould groups and crossbeam spindle motor mould group are respectively arranged with grating encoder and are controlled.
Further, pinboard is installed on the mover of crossbeam spindle motor mould group, is equipped with up and down between pinboard and crossbeam
The guide rail of upside-down mounting.
Further, crossbeam both ends and pinboard corresponding position are equipped with anticollision buffering adhesive.
Further, guide rail is equipped with two groups, is respectively arranged on the upper and lower ends of pinboard.
The invention has the beneficial effects that:
1) double columns for driving spindle motor mould group and the crossbeam of crossbeam spindle motor mould group pass through casting straight forming, column and crossbeam
On stator rabbet formed by machine tooling, have the advantages that structure is simple, easy to process, at low cost.
2) crossbeam of crossbeam spindle motor mould group is cast member, and the rigidity of structure is big.
3) stator rabbet of double drive spindle motor mould groups and crossbeam spindle motor mould group is processed as two sides, primary permanent magnet straight-line electric
Two movers of machine share a stator, and space is small, and thrust is big.
4) guide rail of crossbeam spindle motor mould group uses upside down mode, and adjustment is convenient, is easily guaranteed that the straight of the direction of motion
Dimension, and muting function is good.
5) gantry platform is controlled using grating encoder, and positioning accuracy is high, location error is small and has good stability.
