Description

The bench drill battery saving arrangement

Technical field

The utility model relates to the machining equipment field, specifically is a kind of bench drill battery saving arrangement that is used on the bench drill.

Background technology

In machining was produced, a lot of companies tended to the machined link of product is reasonably made up arrangement in order to enhance productivity.As for the end cap product, need use lathe in machining, machining center mills several procedures such as boring, the processing of multiaxis tapping machine and bench drill processing side opening, therefore these several procedures is combined into a production cycle, lines up the distribution of C shape adding formula equipment.Like this, only need an operative employee to finish above-mentioned all process steps, saved the work flow of production cost of products and shortening product greatly.If when general each product total consuming time was 162 seconds, only be 7 seconds the actual process time of bench drill.Can there be following shortcoming like this:

1) because bench drill vacant chronic, if just start bench drill No. one time when processing side opening at every turn, in other words, product of every processing will start bench drill No. one time, and the number of starts of bench drill is frequent like this, operates pretty troublesome.

2) if, can cause the significant wastage of bench drill electric energy, further increase production cost for the trouble degree that reduces operation makes bench drill in running order always.

The utility model content

Technical problem to be solved in the utility model is a kind of simple to operate, economize on electricity to be provided, thereby to reduce the bench drill battery saving arrangement of production cost.

For solving the problems of the technologies described above, the bench drill battery saving arrangement that the utility model provides, comprise bench drill collar bush and bench drill shell, described bench drill collar bush is slidingly fitted in the bench drill shell, and described bench drill collar bush and bench drill shell are provided with the switching device that can automatic control console bores motor start-up or stop.

After adopting above structure, the utility model is compared with prior art, has following advantage:, in process, need not operating personnel's deactivation or stop the bench drill motor like this because the switching device that can automatic control console bores motor start-up or stop to be installed on bench drill; Simultaneously, when bench drill is not worked, also can make the bench drill main shaft be in halted state, reduce waste of electric energy greatly, thereby reduce production costs.

As improvement, described switching device comprises buting iron, near switch, control transformer and AC relay, wherein, described buting iron is installed on the bench drill collar bush, describedly be installed on the bench drill shell near switch, described buting iron is positioned near under the switch; Describedly be electrically connected with the motor and the forceful electric power power supply of bench drill by control transformer near switch and AC relay.Described motor is a threephase asynchronous.After adopting this structure, the structure of this switching device is reached oversimplify most, also control the running of bench drill motor simultaneously easily.

As further improvement, described electrical connection is meant, all be connected in the low-pressure end of control transformer in parallel near switch and AC relay, the high-pressure side of control transformer is electrically connected with threephase asynchronous and forceful electric power power supply, and described threephase asynchronous is connected with three-phase forceful electric power power supply by the contact switch of AC relay.After adopting this structure, can realize the power savings of bench drill better, make whole device effectively simple more.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.

By Fig. 1～the utility model bench drill battery saving arrangement shown in Figure 3, it comprises bench drill collar bush 4 and bench drill shell 1, and described bench drill collar bush 4 is slidingly fitted in the bench drill shell 1.Described bench drill collar bush 4 and bench drill shell 1 are provided with and can bore the switching device that motor 5 starts or stops by automatic control console.

Described switching device comprises buting iron 3, near switch 2, control transformer 7 and AC relay 9.Wherein, described buting iron 3 is installed on the bench drill collar bush 4, describedly is installed on the bench drill shell 1 near switch 2, and described buting iron 3 is positioned near under the switch 2.Describedly be electrically connected with the motor 5 and the forceful electric power power supply of bench drill by control transformer 7 near switch 2 and AC relay 9.Described motor 5 is a threephase asynchronous.Described electrical connection is meant, all be connected in the low-pressure end 8 of control transformer 7 in parallel near switch 2 and AC relay 9, the high-pressure side 6 of control transformer 7 is electrically connected with threephase asynchronous 5 and forceful electric power power supply, and described threephase asynchronous 5 is connected with three-phase forceful electric power power supply by the contact switch 10 of AC relay 9.

Course of action of the present utility model is such: the end cap series products is carrying out when lathe in machining, machining center mill these operations such as boring, the processing of multiaxis tapping machine, the bench drill collar bush 4 that the bench drill main shaft is housed is positioned at the top, top, be that bench drill collar bush 4 and bench drill shell 1 are from getting recently, on this moment bench drill shell 1 sense buting iron 3 on the bench drill collar bush 4 near switch 2 after, near switch 2 energisings.The AC relay 9 of low-pressure end 8 that is connected control transformer 7 like this is by near switch 2 short circuits; electric current is without AC relay 9; this moment 9 li of AC relays the coil no power; its contact switch 10 that connects forceful electric power power supply and threephase asynchronous 5 just is in off-state; so equal no power of three-phase on the threephase asynchronous 5; threephase asynchronous 5 can not turn round, and the main shaft of bench drill is in stopped status like this.When the end cap series products proceeds to this procedure of bench drill processing side opening, only need bench drill to shake handle, bench drill collar bush 4 is moved downward, and the buting iron 3 on the bench drill collar bush 4 has just broken away from the induction zone near switch 2 on the bench drill shell 1 like this, makes near switch 2 outages.Be connected AC relay 9 energisings of the low-pressure end 8 of control transformer 7 like this, this moment 9 li of AC relays coil electricity, the contact switch 10 that connects forceful electric power power supply and threephase asynchronous 5 is closed, entry into service after the three-phase of threephase asynchronous 5 is all switched on, the main shaft that drives bench drill rotates, and this moment, the main shaft of bench drill was in running order.

After completion of processing, unclamp the bench drill handle, the effect that bench drill collar bush 4 is subjected to coil spring power upwards returns to the position that stopped originally, make the induction zone on the close again bench drill shell 1 of buting iron 3 on the bench drill collar bush 4 near switch 2, according to above electrical principle, contact switch 10 on the threephase asynchronous 5 is in off-state, and the motor 5 of bench drill stops operating automatically.

The utility model is not limited to above-described structure, can also be travel switch near switch 2 wherein, and this moment, buting iron 3 will have the action of a shake-up with travel switch.

The utility model also is not limited to above-described structure, and wherein threephase asynchronous 5 can also be other motor, and the mode of connection of motor will adapt to the feature of motor at this moment.
