Essence of the shift fork on articles holding table is realized by left port detent mechanism, right output port detent mechanism, linkage section detent mechanism
Certainly behind position, shift fork is compressed by hold-down mechanism, later, work of numerical control machine can process corresponding hole on shift fork, dress
Set compact-sized, ingenious in design, positioning accuracy is high, effectively increases the machining accuracy and processing efficiency of product.
When specifically used, for convenience of the present invention is understood, it is described in conjunction with attached drawing；
Before shift fork is put into, according to design drawing, the position of left port detent mechanism, linkage section detent mechanism is regulated,
For left port detent mechanism by screwing left location nut again after rotating left top screw, linkage section detent mechanism passes through movable floor
Sliding in long gain reaches tightening screw after design position.
Shift fork is placed on the collet of articles holding table, on the left of shift fork with right baffle-plate against, the face paste of interconnecting piece and column is closed, it
Right top screw is rotated by force application rod afterwards so that the elastomer block of right top screw is bonded with the surface of shift fork, and the position of shift fork obtains
To uniquely determining, meanwhile, during drilling, elastomer block plays the role of shock-absorbing to a certain extent, later by compacting machine
Structure compresses shift fork.
The working condition of hold-down mechanism is as follows：Manual rotation's handle, turning set accordingly rotate, i.e., axis pin is relative to lateral spiral shell
Spin slot moves, when axis pin 83 at lateral helicla flute 821 from high-order toward lower position when, lifting shaft 85 down, when axis pin 83 exists
At lateral helicla flute 821 when horizontal movement, lifting shaft is in stable state (i.e. the Working position of shift fork).It machines, works as pin
For axis 83 from low level toward when high-order movement at lateral helicla flute 821, lifting shaft 85 is up multiple under the action of the resetting spring of top
Position.Lifting shaft only move up and down (since lifting shaft is fixedly connected with T-type casing, T-type casing is oriented to by key, thus lifting shaft only
Straight line up and down motion can be done), elevating movement is passed to spinning axis, the process that spinning axis rises on straight line by lifting shaft by cross bar
In, due to being equipped with axis pin I thereon, axis pin I is oriented to by vertical helicla flute, when axis pin I is oriented to by straight slot, shows as spinning axis
Linear motion, compact heap accordingly moves linearly；When axis pin I is oriented to by chute section, the linear motion of spinning axis is shown as
With the aggregate motion of rotary motion, deflect while compact heap accordingly moves linearly；
Specifically, manual rotational handle makes axis pin I reach the peak of chute section, is put into shift fork at collet later,
Slowly handle is resetted, during reset, is first oriented to by chute section, compact heap slowly occurs while declining toward shift fork
Interior rotation, when axis pin I covers chute section, compact heap is orthogonal with the marginal position of shift fork, and compact heap no longer rotates, axis pin I after
Continuous to cover straight slot, compact heap during the decline compresses shift fork.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
