The beneficial effects of the invention are as follows：
The present apparatus can make workpiece realized in clamping process around automatic centering in both direction, it is ensured that workpiece in batch
Only needed once to knife when being processed on CNC milling machine.
Due to there is provided the grip block that can be horizontally slipped, by the movable of clamp bracket, making left grip block and right folder
It is synchronously relatively close and realize clamping to workpiece while realize the centering of left and right directions positioning to hold block, simultaneously as setting
The spring of left and right flexible member and wedge block upper end has been put, has made two grip blocks of left and right reliable operation in opposite deviate from.
Due to there is provided centering component, in left and right grip block it is relatively close and during clamping workpiece, the workpiece will
Ejector pin is pressed into left grip block and makes fore-stock and after-poppet while press to workpiece, so that workpiece is also realized automatically in fore-and-aft direction
Centering function.
Due to that there is provided lifting screw, workpiece can be risen to required position before clamping, make workpiece top surface liter
Go out the certain height of left and right grip block top surface, prevent that grip block is by cutter institute mill off in process, in addition, lifting screw
It can also be used to after work pieces process is complete workpiece ejecting grip block, in order to be pushed into workpiece under the driving of sub-material drive device
Chute feeder.
To be completed because there is provided clutch, two actions of clamping and jacking by clamping jacking motor, reduce motor number
Amount, reduces manufacturing cost.
Due to taking over a business the sensor of extreme lower position there is provided reference block and for detection, enable digital control system that work is set automatically
Part stretches out the height of left and right grip block top surface.
Whole device structure is relatively simple, stabilized structure, reliable operation, and rectangular piece can not only be realized around
In both direction centering positioning, reduce the non-cutting time of process operation, and realize workpiece top surface stretch out grip block away from
From control, it is ensured that the security of process operation.
By later mode, those skilled in the art can make various according to mode of operation within the scope of the invention
Change.
