Abstract
The utility model relates to a workpiece centering fixture capable of being pressed tightly with an own oil cylinder. The workpiece centering fixture comprises a fixture body, a thrust ball bearing, a thrust bearing washer, a deep groove ball bearing, a clamping cone seat, a front clamping cone disk and a rear clamping cone disk, wherein a piston is arranged in the fixture body; the front end of the piston is provided with a guide bushing seat and a compressed spring; a guide bushing is arranged at the front end of the guide bushing seat; through the clamping motion produced by the rear end of the fixture, a workpiece is clamped through the front clamping cone disk and the rear clamping cone disk; the piston is used for feeding oil through a hydraulic oil port P, and discharging oil through a T oil port; through the oil passage in the fixture body, the piston moves backwards to drive the guide bushing seat and the guide bushing to move backwards, thereby tightly closing to the end surface of the workpiece, and realizing the guiding function of a drill hole. As the front clamping cone disk and the rear clamping cone disk are adopted, and the own oil cylinder can be pressed tightly and can be used for ejecting the centering fixture structure of the workpiece, the centering requirement of the workpiece is ensured, and the workpiece can be separated with the front clamping cone disk, and moreover, the workpiece centering fixture has the advantages of simple structure, convenient in operation and the like.
