Description
Technical field
The utility model relates to motor stator field, is specifically related to a kind of calibration clamping device.
Background technology
Winding on motor stator is the chief component of stator core.Stator winding is coupled together in a certain way and is formed stator circuit by coil groups, produces induced potential with rotor flux relative motion, realizes the conversion of mechanical energy-electric energy.
Different from setting-in wire laying mode according to the shape of coil winding, can be divided into centralized and distributed two classes.Coiling and the setting-in of centralized winding are fairly simple, but efficiency is lower, and runnability is also poor.The current AC electrical machine stator overwhelming majority is all application distribution winding, according to different machines, model and coil embedding around process conditions, motor designs separately and adopts different winding type and specification, therefore the technical parameter of its winding is not identical yet.
Winding in stator core, no matter adopt which kind of mode to distribute, all needs winding to be assembled in stator core, and winding is mainly to assemble by the mode of coiling and stator core.For current work flow, majority is that copper cash is wound on basic mode, and then with manual type rule, also have employing manually not by groove around embedding, process velocity is slower, output is lower.With manual type, the matrix that is wound with copper cash winding is packed into more time-consuming and difficult construction in stator core body; Artificial coiling is comparatively loose, and during design of electrical motor, copper factor should not too highly affect stator core performance.
Along with scientific and technological development, occurred that at present a kind of mode of bracing wire is embedded into winding in line embedding groove.In bracing wire process, because stator core is held device, clamp, and a phase winding can only be sent in the line embedding groove of stator at every turn.Current clamping device cannot rotate, and therefore, in the time need to sending into winding mutually to next of stator, can only stator be rotated to an angle by manual type by unclamping after clamping device, and such mode operates and wastes time and energy.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of calibration clamping device, and the utility model can optionally rotate the workpiece of clamping as required, makes the rotation process of workpiece time saving and energy saving.
The technical scheme solving the problems of the technologies described above is as follows:
Calibration clamping device, comprise workbench, holder, adapter sleeve, supporting seat, floating holder, drive unit, rotating shaft, bevel pinion, bevel gear wheel, one end of holder is fixed on workbench, adapter sleeve is arranged on holder, one end of supporting seat is fixed on the internal face of adapter sleeve, the other end of supporting seat is in adapter sleeve and to the radially extension of adapter sleeve, one end of floating holder is fixed on the internal face of adapter sleeve, and the other end of floating holder is in adapter sleeve and to the radially extension of adapter sleeve; Drive unit output is connected with one end of rotating shaft, the other end of rotating shaft is fixedly connected with bevel pinion, the parallel longitudinal of the axial and workbench of rotating shaft, bevel gear wheel and bevel pinion are intermeshing, the axially parallel of the axial and adapter sleeve of bevel gear wheel, bevel gear wheel and adapter sleeve are fixed as one, and described adapter sleeve is enclosed within rear on holder and is slidably matched with holder.
Adopted such scheme, by drive unit, driven bevel pinion, bevel pinion drives bevel gear wheel to rotate, and bevel gear wheel drives adapter sleeve to rotate.Because the stator core of motor at least needs the winding of coiling two-phase, for the mode with by bracing wire, winding is embedded into the mode in the groove of stator core, often draw is once that the winding of a phase is embedded in the groove of stator core, therefore, for all the other phases, if above-mentioned rotating manner is not set, by artificial mode, do not rotate stator core, so relatively waste time and energy.Therefore, after embedding complete mutually, need to embed other phase times, the power sending by drive unit, makes adapter sleeve drive stator core to rotate an angle to the position needing, and without adopting manual type to remove to rotate stator core, has time saving and energy saving advantage so again.
Further, described calibration clamping device also comprises a bearing, flange, trim ring, locking positioning mechanism and contiguous block, the lower end of bearing is fixed on workbench, flange is provided with the through hole passing for rotating shaft, the lower end of flange is positioned on the upper surface of bearing, holder is fixed on the upper surface of flange, after trim ring surrounds flange, trim ring is fixedly connected with workbench, described locking positioning mechanism is by latch segment, latch and support form, latch segment is fixed on the upper surface of flange, latch segment is provided with jack, support is fixed on workbench, support is provided with through hole, one end of latch is inserted in the jack on latch segment after passing the through hole on support, contiguous block is fixed on holder.If there is no said structure, calibration clamping device is directly fixed on workbench, and when adapter sleeve is under the dynamic action of drive unit output, adapter sleeve can only carry out gyration centered by the axle center of self.When stator core one after rule, primary need takes out mould, second, after taking out mould, need the good winding of embedding to carry out shaping, because mould need to take out from the side towards puller system, and between calibration clamping device and puller system between limited space, therefore, if calibration clamping device is not rotated to an angle, in narrow space, rule mould is taken out, and winding is carried out to comparatively difficulty of shaping.After increasing said structure, need to make calibration clamping device take workbench longitudinally as axle center, carry out gyration time, first remove the locking of locking positioning mechanism to flange, and by screw, contiguous block and adapter sleeve are fixed, the power of drive unit output is delivered to after bevel gear wheel by bevel pinion, the turning effort power of bevel gear wheel is owing to there is no the locking positioning mechanism restriction circumferential to flange, this active force will be passed to holder, by holder, pass to flange, flange carries out gyration centered by the axle center of self, make the adapter sleeve of calibration clamping device rotate an angle, so that taking-up mould, and be convenient to the good winding of embedding to carry out shaping after taking out mould.
Further, described holder comprises base and is fixed on the lasso on base.Base is played a supporting role, and lasso is convenient to form and be slidably matched with adapter sleeve, adapter sleeve is played a supporting role simultaneously, and adapter sleeve is rotated under the support of lasso.
