Automatic Measurement of the piston storage means

The present invention relates to the field Piston device, in particular, discloses a high accuracy and a piston having a memory function storing an automatic measuring device which comprises a detection frame, a rotary shaft is provided with two detection both ends of one side of the rack, on the shaft is provided with an endless chain group, rectangular grooves provided side by side on the endless chain group, provided at one end detecting means detects the frame side rectangular groove, is provided above the transverse rail of the rack detection, provided vertically downward pneumatic laterally movable in the transverse slide jaw, automatic measurement of the piston storage means, which is provided with an endless chain group and the detection side of the rectangular groove in the rack may temporarily store processed finished piston, while the transmission piston can be implemented, and in the transmission process, sampling gripping jaws by a pneumatic piston, a dome from the recess and the inner diameter detected by the detector on the detection means, simple and convenient, and can simultaneously detect two, greatly reducing the detecting step, improve the detection efficiency, quality assurance of the piston.
