1. Measurement of action distance; When the action piece is close to the sensing surface close to the switch from the front, the distance close to the switch action is the action distance close to the switch, and the measured data should be within the parameters of the product.
2. Determination of release distance; When the action piece is separated from the sensing surface close to the switch from the front, and the switch is turned from action to release, the distance of the action film from the sensing surface is measured.
3. Determination of the return difference H; The value of the difference between the action distance and the release distance.
4. Action frequency measurement; Use the speed-regulating motor to drive the bakelite disc, fix a number of steel sheets on the disc, adjust the distance between the switch sensing surface and the action piece, about 80% of the switch action distance, roll the disc, make the action piece close to the switch in turn, install a speed measuring device on the disc spindle, and the switch output signal is shaped and connected to the digital frequency meter. At this time, the motor is started, and the speed is gradually increased, and the action frequency of the switch can be directly read out by the frequency meter under the condition that the product of the speed and the action piece and the frequency count are equal.
5. Repeatability determination; The action piece is fixed on the measuring tool, and the movement speed of the action zone close to the switch from the front of the switch sensing surface is controlled at 0, 1mm/s from 120% of the switching action distance. When the switch is in action, the reading on the gage is read out, and then the action zone is exited to disconnect the switch. Repeat this 10 times, and then calculate the difference between the value of the 10 measured values and the small value and the average value of 10 times, and the large difference is the repeatability error.
