The specific embodiment

Below in conjunction with accompanying drawing 1-3, architectural feature of the present utility model is more at large described.

A kind of automatic tapping device based on hand drill machine, comprise hand drill machine body 2, integrated device plate 1, annulus fixed sleeve part 3, it is characterized in that: this integrated device plate 1 is by power supply, contactor, relay, power supply indicator 119, plug 100, socket 104, selector switch 105 and approach switch 115, motor positive and inverse A.C. contactor KM, time relay KT, approach switch signal trailing edge integration trigger 108 is combined into approach switch rising edge integration trigger 110 electrical equipment such as grade, in described integrated device plate 1, there is an electric fixed head, described power supply, relay, transformer, motor positive and inverse A.C. contactor, the time relay, approach switch signal trailing edge integration trigger and approach switch rising edge integration trigger etc. are all fixedly arranged on electric fixed head.Comprise annulus fixed sleeve part 3, this annulus fixed sleeve part 3 is comprised of movable annulus holder 117, static annulus holder 116, approach switch 115, stroke adjustment block 118; Movable annulus holder 117 is fixedly arranged on the wind of hand drill machine body 2, static annulus holder 116 is fixedly arranged on wind inner side, with the parallel installation of movable annulus holder 117, stroke adjustment fast 118 is fixedly arranged on movable annulus holder 117, approach switch 115 is fixedly arranged on movable annulus holder 117, and with electrical equipment circuit board 1 line.

The utility model operation principle is achieved in that to be inserted plug in Fig. 1 100 after power supply, indicator lamp 119 lights, selector switch 105 mediates and stops gear, and the attaching plug of former hand drill machine is inserted in this device receptacle 104, now whole set equipment is in Fig. 3 state, fixing approach switch 115 on movable annulus holder 117, parallel with static annulus holder 116 and in induction zone position, there is the sense state of approaching;

When need of work is holed, by 105 groups of selector switches in boring gear, in transformer 101, the electric current of outflow passed through motor reversal A.C. contactor normally-closed contact 106 flow direction motor forward ac contactor coils 107 this moment, motor forward ac contactor coil 107 electric after, motor forward A.C. contactor main contacts 102 closures, socket 104 obtains forward electricity, hand drill machine motor is rotated in the forward, operator presses down handle drill bit and declines and implement drilling operating this moment, after finishing, boring gives away handle, because of elastic force auto-returned, complete drilling operating.

When need of work tapping, by 105 groups of selector switches in tapping gear, in transformer 101, current direction approach switch signal trailing edge integration trigger 108, approach switch rising edge integration trigger 110, the motor forward A.C. contactor of outflow often driven auxiliary contact 109 this moment, auxiliary contact 112 often left by motor forward A.C. contactor, rear cut-off, electric current is obstructed, now motor forward ac contactor coil 107, motor reversal A.C. contactor normally-closed contact 106, all must not be electric, motor is out of service, operator is placed after complete product, press down handle, now movable annulus holder 117 drives approach switch 115 to move with rotatable handle, when approach switch 115 departs from static annulus holder 116, leave induction zone, approach switch 115 breaks, approach switch signal trailing edge integration trigger 108 work in circuit, send one and connect circuit, now, electric current is by approach switch signal trailing edge integration trigger 108 and motor reversal A.C. contactor normally closed auxiliary contact 106, make 107 energisings of motor forward ac contactor coil, thereby the main 102(of motor forward A.C. contactor auxiliary 109) adhesive simultaneously, 107 self-lockings of motor forward ac contactor coil, hand drill strong point is in long-term forward state, along with handle presses down process (being that stroke adjustment block 118 is adjusted position) after assigned address, approach switch 115 contacts with stroke adjustment block 118, the moment of contact, approach switch signal rising edge integration flip-flop operation, electric current is by time relay normally-closed contact 114, motor reversal ac contactor coil 112 and time relay coil 113 simultaneously electric, motor reversal A.C. contactor main contacts 103(auxiliary contact normally-closed contact 106, auxiliary normally opened contact 112) disconnect (adhesive) simultaneously, 107 power-off of motor forward A.C. contactor, 111 self-lockings of motor reversal A.C. contactor, hand drill machine motor reversal this moment, screw tap on motor head is automatically counter goes out hardware products, operator only need give away handle can complete whole tapping operation.

During above-mentioned middle hand drill machine reversion, because motor reversal ac contactor coil 112 is in self-locking state, so time relay coil 113 timing, after timing completely, time relay normally-closed contact 114 disconnects, self-locking circuit cuts off, and allows complete machine in returning to original state, waits for workpiece processing next time;

Above-mentioned middle approach switch signal trailing edge integration trigger 108 and approach switch rising edge integration trigger 110, for instantaneous power device, while being approach switch work, the 110 work work periods of approximately 0.2 second of approach switch rising edge integration trigger, when approach switch quits work, 108 approximately 0.2 second work period of work of approach switch signal trailing edge integration trigger.

Visible the utility model only need manually press down handle and realize the pattern of automatic rotating and former dependence switch motor forward-reverse switch Comparision manually, the utility model can better be saved time, reduce operator working strength, thereby effectively promote the object of operating efficiency.

Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
