| Abstract: | A piston automatic measurement and sorter based on ISA bus are introdu ced. The electric eddy sensors are used to convert the given diameters of 3 sect ions of the piston to frequency signals and the 8253 chip is used to make the tr ansform from frequency signals to data(F/D). The input/output interface is bui lt up by the parallel 8255 chip. The 8253 chip, the I/O interface and computer a re linked by ISA bus. The given diameters of 3 sections of the piston is collect ed by the computer. The experiments show that the accuracy of the machine reache s ±1.5μm and the repeatability ±1.5μm. |
