Preferably, adaptable centering can be replaced according to the shape and size of perforate on the workpiece for treating centering positioning to position
Pin 16.
The operation principle and using method of mechanism is as follows：
Mechanism is installed on lathe, centering and the positioning of circumferential position are carried out to the workpiece on platen,
The circumferential position centering refers to drive workpiece to complete looking for for position during circumferencial direction rotates by alignment tool
Just with positioning；There are the cavity or hole of opening in the upper surface of the workpiece, as the alignment holes with centering detent fit；
Before operation, the initial position of mechanism is exactly the position location after workpiece positioning, i.e. mechanism tumbler
Axis of rotation and positioning after workpiece central coaxial；First, tumbler and alignment device decline is driven to connect by cylinder 4
Workpiece on nearly platen, since centering lower linking plate 17 is stretched out in 16 lower end of centering positioning pin, centering positioning pin 16 is first
Contacted with the upper surface of workpiece, alignment device continues to decline so that workpiece pushes up centering positioning pin 16 together with detection plate 15 upwards
Rise and compress spring 11, when in the triggering of 4 piston of cylinder close to switch 1, cylinder 4 is stopped, also, detection plate 15
It is upper lower close to switch 1 along triggering, show that centering positioning pin 16 has been withstood on the upper surface of workpiece, started by operating personnel
Tumbler driving alignment device rotates, and on the premise of centering positioning pin 16 is kept with workpiece continuous contact, drives centering to determine
Position pin 16 is rotated forward relative to workpiece, is being turned an angle（Rotational angle is indefinite according to Workpiece structure shape, generally omits
Less than 360 ° or 180 ° or 120 ° or 90 ° etc.）Afterwards, centering positioning pin 16 is sprung into the alignment holes of workpiece upper surface, determines centering
Position pin 16 drives detection plate 15 to move down, and triggers lower close switch 2 23, illustrates that centering positioning pin 16 is had been enter into the alignment holes, by
Centering positioning pin 16 drives workpiece to be rotated synchronously with alignment device to complete to rotate forward, and returns to initial position, and then centering fills
Put and reverse rotation is synchronously completed under the action of centering positioning pin 16 with workpiece, and turn again to initial position, afterwards by cylinder 4
Alignment device is risen, during cylinder 4 rises, the action of cylinder 4 can be terminated in triggering close to switch 2 20, it is final complete
Centering and positioning into workpiece.
In use, suitable centering positioning pin 16 can be selected according to the geomery of workpiece to be positioned, and according to
The position of alignment holes is adjusted installation site of the centering positioning pin 16 in detection plate 15 on workpiece；When workpiece to be positioned
For inverted pyramidal structures when, during positioning, centering lower linking plate 17 can be pressed in the upper surface of workpiece, to avoid workpiece tilt
Influence the accuracy of centering positioning.
