Group all includes two fixed spacer pins 14 and a driving lever spacer pin 15, and two of which fixes spacer pin 14 and is located at swing limit respectively
The both sides of position block 12 are then provided with inclined surface 16, above-mentioned driving lever spacer pin 15 and inclined surface in the end for swinging limited block 12
16 are in contact, and driving lever spacer pin 15 is movably connected in slot hole 17, this slot hole 17 is then opened on bracket 1, the driving lever
The bottom of spacer pin 15 is fixedly connected on bogie 18, and bogie 18 is then fixedly connected with above-mentioned adjusting bracket 4.
The radial direction and the work of axial linkage shifting and self-centering apparatus for piston positioning of the utility model embodiment
It is as follows to make process：The present apparatus can position the piston of two kinds of different sizes, and the diameter of the two pistons is different, and diameter is opposite
Smaller piston（It is set to piston a）Corresponding two swings limited block 12, the relatively large piston of diameter（It is set to piston b）Corresponding two
A fixed limited block 11；
When needing to position piston a, cylinder 2 is in recycling state, and two swing the holding of limited block 12 and are mutually parallel
State, the cambered surface for swinging limited block 12 opposite one sides due to two is concyclic, and the circle is the setting circle of piston a, thus this
When by piston a longitudinal direction be put into two swing limited blocks 12 between, as long as can smoothly be put into therebetween, that is, illustrate piston
It has fixed in the axle center of a；
The cambered surface of two fixed 11 opposite one sides of limited block is also concyclic, and the circle is the setting circle of piston b, if it is possible to
Piston b is allowed smoothly to be put into above-mentioned setting circle, illustrating the axle center of piston b can also fix；But since the diameter of piston b is more than
The diameter of piston a, therefore actually two swing limited block 12 and piston b can be hindered to be put between two fixed limited blocks 11；For
It can allow the piston b also on same detent mechanism（That is the present apparatus）Realize centering, control system control cylinder 2 is acted, driven
3 horizontal movement of horizontal moving frame, two inclined avette slot 19 also horizontal movements at any time on adjusting bracket 4, due in avette slot
Connecting pin 7 is connected in 19, and the lifting shaft 6 being fixedly connected with connecting pin 7 has the presence of guide sleeve 5 and horizontal can not transport
It is dynamic, therefore this horizontal movement can be converted into longitudinal movement by inclined avette slot 6 and connecting pin 7, drive lifting shaft 6 and its
9 associated movement of postive stop baffle 8 and workpiece platform on top, according to the specific size of piston a and piston b to the length of avette slot 9
Degree and angle of inclination are designed, ensure the difference in height between two extreme positions of workpiece platform 9 be two pistons it
Between difference in height；
While horizontal moving frame 3 and adjusting bracket 4 move, the bogie 18 being connected with adjusting bracket 4 can also drive two
The transverse movement in slot hole 17 of driving lever spacer pin 15, due to driving lever spacer pin 15 and the inclined surface 16 for the end for swinging limited block 12
Contact, therefore when driving lever spacer pin 15 is moved away from the direction of cylinder 2, pressure no longer is applied to inclined surface 16, so
Under the action of spring 13, swinging limited block 12 can swing out, and this swing is also the motion bit with driving lever spacer pin 15
Put matching, when driving lever spacer pin 15 moves to the extreme position away from cylinder 2, swing the outside of limited block 12 just with position
Fixation spacer pin 14 in outside contacts, and two swing limited blocks 12 completely will be between two fixed limited blocks 11 at this time
Space is got out of the way, and piston b can be smoothly put between two fixed limited blocks 11, and realizes centering；
When needing to be switched to the state of corresponding piston a, it is only necessary to cylinder 2 be controlled to recycle, workpiece platform 9 is driven to drop to
Initial position（The extreme position of workpiece platform 9 on the lower is defined by postive stop baffle 8）, while driving lever spacer pin 15 also can
It presses against inclined surface 16 to move, allows two to swing limited block 12 and inwardly swing simultaneously, spring 13 is compressed, when cylinder 2 is recovered to just
During beginning state, driving lever spacer pin 15 also moves into initial position, swings the fixation /V of the inside and inside of limited block 12 at this time
Pin 14 contacts, and two swing limited block 12 and are restored to the state being mutually parallel, and piston a can smoothly be put into two pendulum at this time
Between dynamic limited block 12 and realize centering；
That is, the present apparatus can pass through simple operations, you can realize the centering of different size piston, while it is only sharp
With a driving device（Cylinder 2）, you can realize that the swing of the height change and two swing limited blocks 12 of workpiece platform 9 is moved
Make, it being capable of effective control cost.
