Description
Technical field
The invention belongs to a kind of stator apparatus of reciprocable machine, be specifically related to a kind of stator structure of reciprocable machine of the stator deformability that takes place when preventing to assemble stator.
Background technology
In general, reciprocable machine is the motor-field with stereochemical structure to be changed to plate shaped, and the mover assembly that forms with flat board is placed on equally on the stator module that forms with flat board, and carries out rectilinear direction according to changes of magnetic field and move.Introduce recently that the handlebar stator module is separated into the outer stator and the inside stator of drum and the fixed gap overlay configuration of being separated by, dispose movably mover assembly between outer stator and the inside stator, on the stator of any side coil is installed in outer stator and the inside stator, and on the Dui Ying mover assembly magnet is set therewith, the reciprocable machine that mover is moved back and forth vertically according to the magnetic direction of coil.
As shown in Figure 1, 2, existing reciprocable machine comprises the stator module 10 that forms magnetic field and the mover assembly 20 that moves back and forth along the magnetic field of stator module 10.Stator module 10 forms and the certain spacing of being separated by in the inboard of outer stator 11 constitutes from the inside stator 12 of (t) configuration by the outer stator 11 that forms with cylinder type with cylinder type.Outer stator 11 is inserted in the connecting portion of iron core sleeve 11b that above-mentioned bobbin 11a lateral surface links and casting iron core sleeve 11b by its inboard bobbin 11a that inserts coil (C) and stacked many stator coils (C) and the injection molding body 11c that is fixed on the bobbin 11a constitutes.Bobbin 11a forms with the ring-like shape of insulators such as plastics with interior sky.Iron core sleeve 11b inserts fixing " " word shape mutually and forms with relative therewith " " word shape that falls in bobbin 11a both sides.Injection molding body 11c constitutes with insulants such as foams and the connecting portion of binding bobbin 11a outer peripheral face and iron core sleeve 11b is fixed together.Mover assembly 20 constitutes with equidistantly fixing magnet 22 along circumferencial direction by disposing between outer stator 11 and the inside stator 12 on mover body 21 movably and mover assembly 21 outer peripheral faces corresponding with the coil (C) of stator module 10.
Above-mentioned existing reciprocable machine action is as follows:
Give coil (C) input current of outer stator 11, then coil (C) around form magnetic field and after outer stator 11 1 effluent roads flow into inside stator 12, again flow into outer stator 11 opposite side streams, formed a kind of closed loop like this, place the magnet 22 of mover assembly 20 on the magnetic field that forms by coil (C), the magnetic field interaction that magnet 22 and coil (C) form is so mover body 21 carries out the reciprocating motion of straight line along magnetic direction.
In order to make such reciprocable machine, at first the stator coil (C) at many of steel plate punching presses " " word shape overlaps 11b to these with " " word shape or " " word shape laminated iron core that falls afterwards, iron core sleeve 11b after certain mould is inserted into the bobbin 11a lateral surface of coil (C), is injected injected plastics material the connecting portion injection moulding of bobbin 11a lateral surface and iron core sleeve 11b is fixed as one.But, in above-mentioned existing reciprocable machine, the convergent force that injection pressure that takes place during because of the injection injection article or injection molding body sclerosis take place, the center position that the part of iron core sleeve 11b is subjected to outer stator 11 as shown in Figure 3 presses down and is out of shape, coil distance (t) between outer stator 11 and the inside stator 12 narrows down and can not keep suitable space thus, makes the reliability and the decrease in efficiency of motor.
Summary of the invention
The present invention is for the shortcoming that solves existing reciprocable machine proposes, and its purpose is to provide a kind of stator structure that is injection molding the reciprocable machine of material distortion original form when preventing to make outer stator.In order to achieve the above object, the technical scheme of the stator structure of reciprocable machine of the present invention is: the bobbin that includes ring-like formation and insertion coil, stacked many stator coils and be inserted in a plurality of the 1st iron core sleeve and stacked many stator coils on the bobbin and contact with the 1st iron core sleeve and to be attached at a plurality of the 2nd iron core sleeve of bobbin lateral surface radially with radial, the 1st support that is fixed on the 1st iron core sleeve contact back side be fixed on above-mentioned the 2nd iron core sleeve and contact the 2nd support at the back side, clamp a plurality of fixedly clips of fixedly connected the 1st iron core sleeve and the 2nd iron core sleeve behind the 1st support and the 2nd support.Like this, assemble iron core sleeve accordingly in the annular coil frame left and right sides, the connecting portion of its both sides iron core sleeve is fixed without injected plastics material and is fixed after fixedly clip is clamped, so can prevent the outer stator distortion that the injected plastics material injection pressure of generation caused when injected plastics material injected in advance, and keep certain clearance between outer stator and the inside stator thus, improved the stability and the reliability of reciprocable machine.
