1. Gear machining quality control cases <br> <br> driven gear is the most widely used car transmission gear to a driven gear Beverly car detection example, talk detection control gear machining quality.
(1) First gear driven gear processing technology brief OP10 car first end / OP20 car second end / OP30 hobbing / OP40 plug combined gear / OP50 chamfering / OP60 combined tooth inverted corner / OP70 shaving / OP80 cleaning (in heat treatment workshop) / OP90 heat treatment / OP100 cleaning (in heat treatment workshop) / OP110 spray molybdenum / OP120 cleaning on catenary / OP130 shot peening / OP135 shot blasting / OP140 honing hole / OP150 grinding cone and inner hole / OP160 cleaning / OP170 bump and rework inspection.
(2) One-stop driven gear machine processing quality difficult point detection method 1OP10 After turning the first end face, the inspection process diagram is shown in Figure 1. It is necessary to detect the first end face to the inner hole jump 31 items, the cone surface and the shoulder outer circle Facing the coaxiality of the inner hole 30, 35 two. Since the roughing is not suitable for the inspection tool, the measurement is programmed using a coordinate measuring machine.
2OP20 turning the second end face, the inspection process diagram is shown in Figure 2. It is necessary to detect the three end faces of the second end to the inner hole of the jump 25, 26, 27 three items, the outer circle facing the inner hole of the coaxiality 29 items, the shoulder The perpendicularity of the end face to the inner hole is 28 items. With the OP10 sequence, the measurement is programmed using a coordinate measuring machine.
After the 3OP30 hobbing, it is necessary to detect the radial comprehensive error of the gear. The radial comprehensive error includes 4 maximum center distance variation, that is, the maximum value within one week is 0.06 mm, and the average dispersion difference is 6 = R = (A max + A min )/2 . The measuring device is a gear double-faced instrument, and the measurement diagram is shown in Figure 3.
