Detailed description of the invention
Be below specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiments.
As shown in Figure 1, this Handheld electric hydraulic tool comprise middle part have for hand-held handle part 1a body 1, be connected to body 1 front end binding clip 2, be arranged at the front side of body 1 pressure control knob 3, be arranged at can drive the driving mechanism of binding clip 2 action, control circuit 4 and being connected to the display screen 5 that can show the duty of Electric hydraulic tool of rear end on the upside of body 1 in body 1.The front side of body 1 is also provided with the illuminating lamp 15 that can throw light on to body 1 front; The bottom of body 1 is provided with built-in power 11, and built-in power 11 place is connected with the electric quantity of power supply detecting unit 12 of the dump energy that can detect built-in power 11, and this electric quantity of power supply detecting unit 12 is connected with control circuit 4.
Specifically, driving mechanism comprises the hydraulic cylinder 18 be arranged in body 1, shoe cream room 19, hydraulic pump 20, drive motors 21 and can control the motor-drive circuit 22 of duty of drive motors 21, be connected respectively by oil duct and oil leak hole between hydraulic cylinder 18 with shoe cream room 19, and drive motors 21 is connected with hydraulic pump 20 and is pressed in hydraulic cylinder 18 by the power oil in shoe cream room 19 by this hydraulic pump 20.In the present embodiment, as shown in Figure 4, hydraulic cylinder 18 place is also provided with the pressure sensor 6 of the output pressure that can detect this Electric hydraulic tool, this pressure sensor 6 and pressure control knob 3, motor-drive circuit 22 are all connected with control circuit 4 with display screen 5, the syndeton of driving mechanism and operation principle identical with the driving mechanism in existing Electric hydraulic tool.
As shown in Figure 2, display screen 5 place of this Handheld electric hydraulic tool is also provided with can select the pressure selection button 7 of the pressure upper limit value preset, can start or closing control circuit 4 power button 8 and the light switch 16 of open and close of illuminating lamp 15 can be controlled, pressure selection button 7, power button 8 and light switch 16 are all connected with control circuit 4 to realize controlling.
As shown in Figure 3, this Handheld electric hydraulic tool also comprises counter 9 that the number of times that can be pressed to pressure control knob 3 that is all connected with control circuit 4 counts, for storing the timing unit 14 that the memory 10 of accumulation work times (namely pressure control knob 3 is pressed and the number of times decontroled), the time can pressed power button 8 and stand-by time carry out timing, the buzzer 17 that can report to the police and being connected to the pressure pulse signal generator 23 that can detect its current signal at drive motors 21 place.
When using this Handheld electric hydraulic tool, first need press the power button 8 at display screen 5 place of rear end on the upside of Electric hydraulic tool and keep, now, the time that timing unit 14 pairs of power buttons 8 are pressed carries out timing, when power button 8 length temporally reaches 3 seconds, control circuit 4 starts work, and display screen 5 lights.As do not pressed power button 8, then this Electric hydraulic tool does not work.While display screen 5 lights, the dump energy situation that control circuit 4 detects according to electric quantity of power supply detecting unit 12 respectively and the accumulation work times information that memory 10 place stores send corresponding electric quantity signal and work times signal to display screen 5 to control its display dump energy and accumulation work times.Again according to the difference of actual user demand, before use, by pressing the pressure upper limit value that pressure selection button 7 is selected to pre-set.
Afterwards, binding clip 2 place is placed in by needing the workpiece carrying out processing, the handle part 1a place of hand-held body 1 and by finger by pressure control knob 3 by earth, control circuit 4 receives the closure signal that pressure control knob 3 sends and carries out processing and send corresponding control signal and start work to motor-drive circuit 22 to control drive motors 21, and then is worked by structure driving binding clips 2 such as hydraulic pumps 20.
Simultaneously, the number of times of pressing of counter 9 pairs of pressure control knob 3 counts, and respectively this work times is sent to memory 10 place stores through control circuit 4, is sent to display screen 5 place display accumulation work times.The pressure sensor 6 being arranged at hydraulic cylinder 18 place then detects the output pressure at this place and sends to control circuit 4, pressure signal is sent to display screen 5 to show current output pressure by control circuit 4, when this force value exceeds the preset pressure value selected by pressure selection button 7, control circuit 4 controls drive motors 21 and quits work.Simultaneously, the pressure pulse signal generator 23 at drive motors 21 place also detects the current signal of drive motors 21 and is sent to control circuit 4 and processes, control circuit 4 can according to this pressure pulse signal generator 23 feed back the actual output pressure that force value and pressure sensor 6 feed back and carry out contrasting and providing error display.
When output pressure constantly increases to close to limit pressure, user can unclamp pressure control knob 3 a little, makes it be in half releasing orientation, and now, control circuit 4 controls drive motors 21 no longer increases output pressure, keeps current output state.
When user is totally released pressure control knob 3, end-of-job, user can vice-minister close to make control circuit 4 by power button for 83 seconds again, or, when the time that Electric hydraulic tool is in holding state (namely not in running order or mode of operation under) reaches 30 minutes, control circuit 4 cuts out automatically.
In the above course of work, if the brightness of working environment is lower, user can press light switch 16 to light illuminating lamp 15 to facilitate work.During the situation that electricity deficiency, output pressure are too high as occurred in the course of work, drive motors 21 works and binding clip 2 does not work (output pressure is zero), buzzer 17 can be controlled by control circuit 4 and sending chimes of doom.For the situation of electricity deficiency, user charges to built-in power 11 by being arranged at place's usb 13 corresponding with built-in power 11 position bottom body 1.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
