And due to different instrument and meters, the gear number of its knob, the moment of resistance while switching, the rotational angle of each gear are all not quite similar, it is exactly the different instrument of same model, also difference to some extent of the strength that turning knob needs, so when design is automatically switched, be difficult to complete different gear switches with a fixed end taken about the point of fixation, same rotational angle.
Summary of the invention
The purpose of this utility model is: a kind of instrument gear automatic switching control equipment is provided, while solving check meter, use artificial fork shift, automaticity is low, efficiency is low, expend the problem of staff's plenty of time, and solving different instrument and meters, its gear number, the moment of resistance, rotational angle are not quite similar, and are difficult to complete with a fixed end taken about the point of fixation, same rotational angle the problem of different gear switches.
The technical solution of the utility model: a kind of instrument gear automatic switching control equipment, include controller, controller is by the startup of signal output device control criterion checking table, controller carries out signals collecting by the first sampling thief to standard checking table, and rotate by the signal controlling motor collecting, motor is connected to gearing by reductor, gearing sends power to knob clamper, knob clamper is to being stirred by the knob of tester, be connected with standard checking table by wire by tester, controller is connected to by tester by the second sampling thief.
Above-mentioned instrument gear automatic switching control equipment, is describedly clamped by tool housing clamper by tester.
Above-mentioned instrument gear automatic switching control equipment, is provided with hummer on described controller.
Above-mentioned instrument gear automatic switching control equipment, is provided with button and charactron on described controller.
The beneficial effects of the utility model: the utility model, in the detection check work of multiple scaled instrument, can replace manual switching knob, complete automatically by the gear switch of tester; The utility model by single-chip microcomputer as controller, by the first sampling thief, standard checking table is carried out to signals collecting, according to the verification process of standard checking table, complete the continuous verification of each gear, the second sampling thief is for the moment of resistance, the rotational angle of the different gears of each instrument, can automatic detection, achieve accurate switching.Knob switch put in place after, device sends pulse, startup checking table descend the detection of a bit, until complete detection a little, then send alerting signal.Use this device can save a large amount of manpowers, improved work efficiency.
