20 electro-motors

The specific embodiment

See also Figure 1 and Figure 2, control device 10 of the present utility model can in build hand-held tool 100 inside in, or be independent of beyond the hand-held tool 100, and be connected with hand-held tool 100 by lead 101 with a monomeric form.Aforementioned hand-held tool 100 is to be example with the electric screw driver, and its application scenario is not limited to electric screw driver, and every electro-motor that is provided with in inside is all the applicable object of the utility model to produce the hand-held tool of power.

As for the circuit block diagram of the utility model one possible embodiments, see also shown in Figure 3, mainly by a microprocessor 11, a motor drive circuit 12, a translation interface 13, and a feedback circuit 14 form; Wherein:

This microprocessor 11 is as the s operation control maincenter, one input end is provided with an one-touch key 15, to receive driving instruction or the halt instruction that the operator sends, its output is to be connected with motor drive circuit 12 by translation interface 13, microprocessor 11 built-in base driving in a period of time flow processs, so that after receiving the driving instruction that is produced after one-touch key 15 is pressed, send the driving signal to motor drive circuit 12.

These motor drive circuit 12 outputs are connected with the electro-motor 20 of hand-held tool, drive electro-motor 20 and control its rotating speed so that send the driving signal by microprocessor 11.

This feedback circuit 14 is to be connected between electro-motor 20 and microprocessor 11 each back coupling end, with the situation to microprocessor 11 back coupling electro-motors 20.

Seeing also shown in Figure 4ly, is the detailed circuit diagram of the utility model one preferred embodiment, and this electro-motor 20 is driven by three phase mains UVW, and this translation interface 13 and motor drive circuit 12 have three groups of circuits respectively, to control three phase mains respectively.The feedback circuit 14 that is connected in again between electro-motor 20 and the microprocessor 11 also has three groups of circuits, with the load current situation of feedbacking respectively on the electro-motor 20, as adjusting the foundation that drives signal.

It is based on the time that aforementioned microprocessor 11 built-in time bases drive flow process, in a fixed time, carry out drive actions, its detailed process sees also shown in Figure 5, after system begins, be whether decision operation person pushes one-touch key 15 to send driving instruction 501, if not, promptly repeat abovementioned steps, if, then send and drive signal 502, in sending the process that drives signal 502, to judge respectively whether a driving time of setting finishes 503, motor torsion whether surpasses preset value 504 and whether one-touch key 15 is again depressed 506, abovementioned steps 503,504,505 is to get back to step 502 to continue to carry out driving work when being false, if step 503,504, during 505 arbitrary establishment, promptly stop output and drive signal 506, get back to step 501 at last.

Can understand by above-mentioned explanation, the utility model provides a driving flow process based on the time, cooperate again touch by after can send the one-touch key that drives instruction, with the running of control hand-held tool internal electric motor whether, because one-touch key drives instruction once pressing to produce, so under the situation, the operator promptly need not continue arduously by on one-touch key; Owing to be,, can allow hand-held tool running a period of time again so only must on the one-touch key of hand-held tool, push once based on the time.With the electric screw driver is example, when being used for locked screw, as set each running 5 seconds, then touch by an one-touch key, electric screw driver promptly turned round for 5 seconds, supposing that lock is paid a screw only must 1 second, and then when screw lock, the torsion of electric screw driver promptly can set value above one, can shut down immediately, if the operator when screw is locked, touches once more by one-touch key, electric screw driver is shut down in addition.Not only can reduce operator's burden whereby, also can meet different use occasions and operating habit.

If pay 25 to lock a working day, 000 screw is an example, utilize the aforementioned manner locked screw, every lock pay a screw press an one-touch key only must be consuming time 0.1 second, lock pays 25,000 screw only must 2,500 seconds, that is according to aforesaid mode of operation, the accumulated time that the operator presses one-touch key intermittently only is 42 minutes, pins the mode of operation of clinching switching plate continuously with prior art, and lock pays 25,000 screw, must continue to pin the clinching switching plate and reach 208 minutes and compare, the time decreased of console switch 166 minutes significantly reduces the burden to operator's hand; And adopt aforementioned techniques to be used in the continued operation of same object on the production line, not only can reduce operator's burden, also increase yield because of can once being locked into the end.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
