Another technical problem that the present invention will solve is, the control method that a kind of electric tool torque exports is provided, this control method has the function that traditional manual operation exports to control electric tool torque, also there is torsion and export adjustable function, user can the working method of choice for use electric tool according to actual needs, thus it is convenient to make electronic work use, and can reduce work mistake and can also increase work efficiency.
Another kind of technical solution of the present invention is, the control method providing a kind of electric tool torque with following steps to export, is characterized in that: it comprises the following steps:
Step 1, default torsion export gear and microswitch gear; Described torsion exports gear to be had multiple; Each torsion exports gear and is equipped with between corresponding Current Zone; Microswitch shelves preset maximum output current value;
Whether step 2, detection microswitch gear are opened;
Step 3, microswitch gear are opened, outputting torsion, and instrument is started working, when output current reach microswitch gear preset maximum output current value time, enter step 4; Microswitch gear is not opened, and selected torsion exports gear, enters step 5;
Step 4, instrument quit work and enter guard mode, flicker N the rear extinguishing and relay indicating light is reported to the police;
Step 5, instrument carry out work under selected gear, and calculate current output current value, judge whether current current value exceedes the current value range corresponding to gear; If current current value exceedes the current value range corresponding to gear, then enter step 6; Otherwise enter step 7;
Step 6, enter guard mode, stop output current, the extinguishing after flicker N time and relay indicating light is reported to the police, instrument enters the guard mode of no-output;
Step 7, to work on.
After adopting above structure, the control method that electric tool torque of the present invention exports, compared with prior art, has the following advantages:
Due to the control method that electric tool torque of the present invention exports, tool presets torsion exports gear, user can select different gears to carry out work according to the difference of job schedule and machined material, accomplish that torsion exports adjustable, operator is used convenient, reduce work mistake and increase work efficiency.Instrument also presets microswitch gear, and when microswitch gear is opened, torsion exports gear and lost efficacy, and the adjustment that electric tool torque exports has been come by manual operation.Torsion exports gear and microswitch gear can be selected as required, uses more flexible.In addition, microswitch gear presets maximum output current value, can enter guard mode after instrument output current reaches maximum output current value, and instrument can be avoided to burn out because electric current is excessive.Torsion exports gear and is also provided with current protection, and during electric tool work when current value exceedes the current value range corresponding to gear, electric tool just enters guard mode, avoids instrument to burn out because electric current is excessive.
