Description
Technical field
It is used to electro-magnet magnetic yoke being fitted in bottom plate the present invention relates to electromagnet frock technical field, more particularly to one kind
Device.
Background technology
Electromagnet includes yoke and bottom plate, and yoke is fitted on bottom plate during assembling.Traditional press-fitting tool is simple in construction,
Only one of which base and a hydraulic machine, operationally, yoke are inverted and is fixed on base, bottom plate manually is placed on into magnetic
On yoke, then, the mode Pneumatic hydraulic lathe stepped on pin, the head of hydraulic machine, which is fallen, completes press-fiting for yoke and bottom plate
Journey.For the ease of the cooperation of yoke and bottom plate, current yoke is designed as annular shape, and base is provided with can house annular shape
The annular groove of yoke, bottom plate is placed on base, then yoke end is placed in the annular groove of bottom plate, last hydraulic pressure
Lathe enters in yoke pressure side portion into the annular groove of bottom plate.The press-fitting tool of prior art, it is simple in construction, exist it is following not
Foot：During due to press-fiting, bottom plate is manually placed in yoke the subsequent hydraulic machine that just starts and press-fited, if press-fited with placing
The action of bottom plate is not coordinated, and the head of hydraulic machine is easy to be pressed onto the finger of workman and triggers industrial injury, and this side
Formula once places a yoke, press-fits and finished product is removed after completing in the next yoke of placement, press-fit efficiency low.
The content of the invention
The technical problem to be solved in the present invention is to overcome existing technological deficiency there is provided a kind of operative safety, and is pressed
The device for being used to be fitted in electro-magnet magnetic yoke on bottom plate of dress efficiency high.
The present invention technical solution be to provide it is a kind of with following structure be used for electro-magnet magnetic yoke is fitted in bottom
Device on plate：Including hydraulic machine, hydraulic machine is provided with base and drift, and drift is arranged vertically at hydraulic machine
On, it also includes rotating disk and multiple positioning seats for being used to position the yoke and bottom plate of electromagnet；Rotating disk is horizontally set on
On hydraulic machine；Rotating disk is vertically located between drift bottom and base upper surface, and rotating disk is along the circumferential direction provided with more
The individual mounting hole for being used to house multiple positioning seats, mounting hole runs through the upper and lower surface of rotating disk, installs axially bored line and rotating disk
Diameter parallel, positioning seat is vertically slidably connected in mounting hole；Described disk lower surface to base upper surface away from
From more than zero；Described hydraulic machine, which is provided with, to be used to driving rotating disk rotation deliver to multiple positioning seats immediately below drift one by one
Power set；Positioning seat lower end is fixedly connected with the first magnet, and base upper end is fixedly connected with the second magnet, and the second magnet is
Loop configuration, the second magnet of the loop configuration includes being used for the non-active area mutually exclusive with the first magnet and for the
The working region that one magnet attracts each other；Working region on the second described magnet is located at the underface of drift, and the annular
Second magnet of structure be located at positioning seat rotate disk axis rotate when movement locus underface.
The present invention drives rotating disk to rotate by power set, so that by the bottom plate on the positioning seat and positioning seat on rotating disk
Seriatim it is sent to below drift, yoke is pressed into bottom plate with yoke with facilitating drift to push；In this process, Gong Renke
To be placed and taken out bottom plate on the positioning seat away from drift, thus the hand of workman can be thoroughly avoided to be pressed onto by drift
And cause industrial injury；Further, since positioning seat, bottom plate and yoke continuously can be sent to immediately below drift by rotating disk, so
The operating efficiency press-fited can just be substantially increased；Further, since rotating disk has relative rotation relative to base, if under rotating disk
Surface contacts and relatively rotated with base upper surface, then the frictional force between disk lower surface and base upper surface can not only hinder
Hinder the rotation of rotating disk, and harsh noise can be sent；If there is gap between disk lower surface and base upper surface, then punching
When positioning seat of the head on to rotating disk carries out punching press, because positioning seat is to deviate rotating disk axis, then drift will be to rotating disk
An eccentric active force is produced, the active force can cause rotating disk to tremble, so that power set are also had with very big rush
Hit；But can vertically be slided relative to rotating disk by positioning seat in the present invention, then positioning seat is away from drift position
When putting, because the non-active area on the first magnet and the second magnet below positioning seat is repelled, positioning seat energy upward sliding, i.e.,
Positioning seat lower surface is disengaged with base upper surface, and close to forcer position under the drive of rotating disk；When positioning seat turns to punching
When immediately below head, positioning seat is caused due to the sucking action in the second magnet works region on the first magnet on positioning seat and pedestal
Slide downward, until positioning seat lower surface is pushed against base upper surface, that is to say, that in the downward punching press of drift, under positioning seat
The benchmark on surface is the upper surface of pedestal, so, and drift would not produce eccentric in punching press yoke and bottom plate to rotating disk
Power, and rotating disk easily can also deliver to positioning seat one by one drift underface.Therefore, the present invention provides a kind of operative
Safety, and press-fit the device for being used to electro-magnet magnetic yoke is fitted on bottom plate of efficiency high.
As a preferred embodiment, described power set refer to be fixedly connected with motor on hydraulic machine, motor passes through rotating shaft
It is connected with rotating disk bottom.By this preferably, rotating disk can effectively be driven around own axis, so that by determining on rotating disk
Position seat is delivered to immediately below drift one by one.
As a preferred embodiment, described positioning seat upper end is provided with the groove for being used for housing bottom plate, and the depth of the groove is small
In the thickness of bottom plate.It can preferably facilitate the positioning of bottom plate, i.e. bottom plate can be on the basis of groove by this；Further, since recessed
Groove depth is less than base plate thickness, then operating personnel can grasp bottom plate by instrument or finger, facilitate yoke and bottom
Plate press-fit after the completion of pickup.
As a preferred embodiment, the first described magnet refer to N poles upward, S bar magnets extremely directed downwardly, on the second magnet
Working region refers to N poles upward, S the first arc-shaped magnets extremely directed downwardly, the non-active area on the second magnet refer to N poles down, S
The second arc-shaped magnet of pole upward；First arc-shaped magnet is equal with the diameter of the second arc-shaped magnet, and the first arc-shaped magnet and
The center of circle of two arc-shaped magnets passes through the axis of rotating disk.It preferably can effectively ensure that positioning seat turns to the second magnet by this
It can be moved down when above upper working region along axially bored line is installed so that positioning seat lower surface is pushed against pedestal upper surface
On；Positioning seat can be moved up when turning on the second magnet above non-active area along axially bored line is installed so that positioning
Seat lower surface departs from pedestal upper surface.
As a preferred embodiment, described multiple positioning seats are at least three.By this preferably, operating personnel can be at one
Realize that putting part, punching press, pickup three process, i.e. rotating disk turns to a positioning seat when carrying out punching press below drift on rotating disk,
Operating personnel can also be placed the yoke not press-fited and bottom plate respectively to other two positioning seat simultaneously, and taking-up has press-fited
Complete yoke and bottom plate.
