Description
Technical field
The utility model relates to electric tool control technology field, relates to the control device that a kind of electric tool torque exports or rather.
Background technology
Usually the work performed by electric tool, as boring and the turn of the screw, generally with the difference of job schedule and machined material, required moment of torsion also can be different.In the prior art, the adjustment that electric tool torque exports normally has been come by manual operation, but this manual operation makes operator moment of having to pay close attention to the duty of instrument and load situation of change, thus judges when need governing speed.This higher to the operative skill requirement of operator by way of manual operation, and be unfavorable for raising the efficiency.
Utility model content
The technical problems to be solved in the utility model is, provides the control device that a kind of electric tool torque exports, and this control device has torsion and exports adjustable function, operator is used convenient, reduces work mistake and increases work efficiency.
Technical solution of the present utility model is, the control device that a kind of electric tool torque with following structure exports is provided, comprise control unit, electric-motor drive unit, motor and power supply, described control unit and power supply are all connected with described electric-motor drive unit; Described electric-motor drive unit is connected with described motor; Described control device also comprises torsion Drazin inverse unit; Described torsion Drazin inverse unit is connected with described control unit.
After adopting above structure, the control device that electric tool torque of the present utility model exports, compared with prior art, has the following advantages:
The control device exported due to electric tool torque of the present utility model is provided with torsion Drazin inverse unit, the torsion of electric tool can be regulated to export by torsion Drazin inverse unit, user can select suitable torsion to export according to actual needs, accomplish that torsion exports adjustable, operation element is used convenient, reduce work mistake and increase work efficiency.Meanwhile, the state that torsion output display module exports for showing torsion, electric tool is used more directly perceived, person more convenient to use uses.
Improve as one of the present utility model, described control device also comprises microswitch; Described microswitch is connected with described control unit.After adopting this kind of structure, microswitch closes, and power supply directly gives electricity to electric-motor drive unit, thus makes machine operation, and namely electric tool is started working; Microswitch is opened, and control unit controls electric-motor drive unit, can realize torsion and export adjustable.Like this, user can be made to select the working method of electric tool as required.
Improve as another kind of the present utility model, described torsion Drazin inverse unit comprises single-chip microcomputer, LED display module, shift-up control button and downshift control button; Described LED display module, shift-up control button are all connected with described single-chip microcomputer with downshift control button; Described unit machine is connected with described control unit.After adopting this kind of structure, described LED display module exports the state of gear for showing torsion, described shift-up button and downshift button export for regulating electric tool torque, and structure is simple and control is convenient.
Also have a kind of improvement as of the present utility model, described control device also comprises relay indicating light; Described relay indicating light is connected with described control unit.After adopting this kind of structure, described relay indicating light is used to indicate the duty of electric tool, also can be used for display alarm prompting.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Refer to shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the control device that electric tool torque of the present utility model exports, comprise control unit, electric-motor drive unit, motor and power supply, described control unit and power supply are all connected with described electric-motor drive unit; Described electric-motor drive unit is connected with described motor;
Described control device also comprises torsion Drazin inverse unit, microswitch and relay indicating light.Described torsion Drazin inverse unit, microswitch and relay indicating light are all connected with described control unit.Described torsion Drazin inverse unit comprises single-chip microcomputer, LED display module, shift-up control button and downshift control button; Described LED display module, shift-up control button are all connected with described single-chip microcomputer with downshift control button; Described unit machine is connected with described control unit.In this specific embodiment, described LED display module comprises 11 LED lamp, and every LEDs is for showing a gear, and torsion Drazin inverse unit is provided with 11 gears.
See also shown in Fig. 5, the control method that electric tool torque exports, 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.
