Description
Technical field
The present invention relates to technical field of motors, more particularly to a kind of bearing positioning device.
Background technology
Existing armature bearing press mounting mainly uses cold pressing mode.The use of process is open manual operations, press fitting
Process is：First bearing is put into press fitting base, then holds armature to be pressed, and makes armature shaft aiming axis bearing bore, then is led to
Receive and distribute and pull the advantages of armature shaft part is slowly pressed into bearing hole, is pressed in this way by forcing press for convenience of, simple, frock
Input amount is few.But due to being hand-held press fitting, armature shaft cannot keep coaxial with bearing hole all the time during press fitting, axis and axis during press fitting
Bearing bore tilts, and be easy to cause precision bearing and weighs wounded so that motor operation is unstable, and noise is big.It is high quality requirements are not suitable for
The production of motor, its long processing time, efficiency is low, and labor strength is high, and there are security risk.
During existing armature bearing press mounting, armature, bearing are not easy to take out after assembling.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of high in machining efficiency and processing effect is more preferable
Bearing positioning device.
The object of the present invention is achieved like this：
A kind of bearing positioning device, including bottom plate, the positioning groove body that is fixed on bottom plate, in the inner cavity of the positioning groove body
Portion is equipped with top plate, the inner wall clearance fit of the top plate and positioning groove body, and the outer rim of the top plate is uniformly provided with least two cunnings
Dynamic protrusion, the slide protrusion clearance fit is in the bar-shaped trough erected in the cavity wall of positioning groove body, alloing to glide on top plate
Dynamic, the space below top plate is spring cavity, and return spring, the upper end of the return spring and top plate are equipped with the spring cavity
Contact, the space above top plate is bearing accommodating chamber.
By adopting the above-described technical solution, the present invention has the advantages that：
After the completion of press fitting, the armature, the bearing that assemble are raised under the action of return spring, are very beneficial for after assembling
Workpiece is taken out, reduces labor strength.

Embodiment
It is bearing positioning device referring to Fig. 3, the bearing positioning device includes bottom plate, the locating slot being fixed on bottom plate
Body, the inner cavity middle part of the positioning groove body are equipped with top plate, the top plate and the inner wall clearance fit for positioning groove body, the top plate
Outer rim is uniformly provided with least two slide protrusions, and the slide protrusion clearance fit is in the bar shaped erected in the cavity wall of positioning groove body
In groove, slide up and down top plate, the space below top plate is spring cavity, is equipped with return spring in the spring cavity, institute
State upper end and the top plate contact of return spring, the space above top plate is bearing accommodating chamber.
Referring to Fig. 1-Fig. 2, for a kind of device for being pressed armature and bearing, including the upper mold being arranged in parallel successively from top to bottom
Plate, positioning plate, lower template, are uniformly arranged four guide posts between the cope plate, lower template, the guide post lower end is fixed on lower die
On plate, the cope plate, positioning plate and guide post clearance fit, four are both provided between the positioning plate and cope plate, lower template
Root compresses spring, and is respectively fitted on corresponding guide post, and the positioning plate is equipped with armature positioner, is set in the lower template
There is a bearing positioning device, the upper surface of the cope plate is fixed for bearing the seaming chuck of press pressure, under the cope plate
End face is fixed for the push-down head of piezoelectricity pivot, and the bottom plate is fixedly connected by bolt with lower template.
The armature positioner includes stationary positioned structure, the activity orientation structure being oppositely arranged, the stationary positioned
Structure includes the positioning sleeve that cross section is in arc-shaped, and the extrados of the positioning sleeve sets connecting portion to consolidate with positioning plate by bolt
Fixed connection, the intrados of the positioning sleeve are used to be equipped with end plate, the end plate to armature radial positioning, the lower end of the positioning sleeve
For to armature axially position, the end plate to be equipped with the via passed through for armature end axis, and the aperture of the via is more than electricity
The diameter of pivot end axis, the positioning sleeve, the central angle of end plate are more than 180 degree, and the activity orientation structure includes cylinder, described
Arc locating piece is fixed on the piston rod of cylinder, the arc locating piece is used to be matched for clamping tightly armature, the positioning with positioning sleeve
Set, the intrados of arc locating piece are equipped with rubber layer, and the notch for being put into armature, bearing is provided with the positioning plate..
The course of work：
The present invention is prevented on press bed, first by bearing by for being put into armature, the notch of bearing is put into
In the bearing accommodating chamber of bearing positioning device, by armature by for being put into armature, the notch of bearing be put into positioning sleeve, lead to
Cross end plate axially position；Cylinder operation, promotes arc locating piece to clamp armature, and clamping force should not be too large, prevent from injuring armature；Pressure
Machine works, and transmits pressure to armature by seaming chuck, push-down head, armature lower end axis is pressed into bearing；Press return, assembling
Armature, bearing afterwards is raised in the case where compressing the active force of spring, return spring；From for being put into armature, the notch of bearing takes
Go out the workpiece after assembling.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
Cross above preferred embodiment the present invention is described in detail, however, those skilled in the art should understand that, can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
