Workpiece, when detection is completed, back taper pull bar is moved up, and under return spring effect, claw slides back in the chute of dog plate
Position, completes clamped one time testing process.
Compared with prior art, the utility model has the advantages that：
1st, fixture cylinder and clamp body are adopted split-type structural by the utility model, are detachably connected by screw, are being ensured
On the premise of machining accuracy, difficulty of processing is greatly reduced.
2nd, the utility model is inlaid with respectively concentric fairlead at fixture tube inner chamber two ends, improve fixture cylinder with
The concentricity precision of back taper pull bar.
3rd, the utility model clamping structure adopts 12 step claws, more existing three claw and six jaw fixtures, folder
Contact point is wider during clamping of workpieces, substantially increases centering accuracy rate and accuracy of detection, and claw is set to three steps so as to cover folder
The tight scope of application is wider.
4th, the utility model claw substantially increases its surface hard through heat treatment process in the case of internal toughness is ensured
Degree and wearability, improve service life, and its service life was up to 50000 hours.
5th, the utility model center platen is each independently fixed on the lateral surface of dog plate, and is independent with dog plate, platen
Part, prevent claw, dog plate, platen because machining accuracy not enough and heat treatment deformation cause return spring that interference is installed to have some setbacks
Freely, make return spring that certain adjustment space is installed.
