Lift application example below in conjunction with accompanying drawing to be described:
The expansion of application example of the present invention: lock screw electric screw driver only rotates and reverse at present, and its neither one judges position accurately when locking screw, only have screw attack lock on earth motionless till, according to current user raising day by day to the technical requirement of product, application example of the present invention devises the electric screw driver of this adjustable lock screw height, and it can by the requirement distance set by user, realize the height of the screw of Subscriber Application Barring Lock, precision is high, accurate positioning, and uniformity is stablized.Suppose that user wants screw to be locked into distance locking plane 3.5MM, user can be selected by reset knob, and by arriving selected position, system can identify automatically, then carries out rotating signal crawl by encoder, has arrived setting value and has just stopped apart from rear bottle opener.
The lock-screw when electric screw driver attacks screw to bottom, bottle opener stall after locking, stall can give circuit control box signal, circuit control box provides reverse signal, during reversion, encoder passes through pulse counting, (rotary encoder umber of pulse can carry out type selecting according to Product Precision, umber of pulse more high accuracy is higher, it judges that the location of rotating speed is more accurate, ) automatically stop (stroke range of 1.5 circles are exactly probably the distance of 3 ± 1mm) to determine according to the actual conditions of product pinning after 1.5 circles that then reverse, (the distance main engine plants of a lot of door lock pinning all require to reserve at present, to install) desirable pinning height can be adjusted to, realize whole assembling process.
Rotary encoder is used to the device measuring rotating speed, and photoelectric rotary coder, can by the angular displacement of output shaft by opto-electronic conversion, and the mechanical quantity such as angular speed convert corresponding electric pulse to digital output.Technical parameter mainly contains and often turns umber of pulse (tens have to several thousand), and running accuracy from low to high not etc., is determined according to installations and facilities service condition.
Design mainly does overall change from bottle opener control section, encoder is driven to rotate by screwdriver head (screwdriver head place arranges guide pin bushing to device), rotating cycle is controlled by rotary encoder during reversion, (impulse stroke revolution arranges 1.5 turns, adjustment height can also be carried out) according to actual conditions, encoder connecting circuit control box (inner self-control circuit control panel), after counting 1.5 encloses, auto-breaking stops, repeated work successively.
Refer to shown in Fig. 3, for the circuit structure schematic diagram of application example of the present invention, connect drive circuit CPU 20(primarily of electric screw driver power unit 10 and can adopt chip U1-PIC16F877) and relay control unit 50 and electric screw driver 60, main relay control unit 50 and the electric screw driver 60 given provides principal current.Drive circuit CPU 20 is connection control unit importation 80, traffic light system part 30, driver element 40 (can adopt chip U2-2003) and pinning height digital display part 90 respectively, main practical function is for driving main circuit, perform startup, driving control unit importation 80, drive singal lamp display section 30, driver element 40 connects relay control unit 50, electric screw driver 60 and rotary encoder 70, mainly realizes signal conversion and the code device signal conversion of bottle opener control.
As shown in Figure 4, for application example control unit importation of the present invention circuit diagram, control unit importation 80: be by forward-reverse switch 81, pitch regulator 82, pinning height by-pass cock+83/-84 and photoelectrical coupler 85 combine, forward-reverse switch 81, be divided into three gears, mainly rotate forward, close, reversion, pitch regulator 82, the pitch of main regulable control electric screw driver, mainly be divided into 5 gears, access drive circuit CPU 20 respectively, pinning height by-pass cock+83(increases shelves) connect 8 of drive circuit CPU 20 pin, pinning height by-pass cock-84(downshift) connect pin 9, this switch carries out circuit conversion by drive circuit CPU, the pinning height of main adjustment electric screw driver.
As shown in Figure 5, for application example enforcement division parallel circuit schematic diagram of the present invention: be by driver element 40, relay control unit 50, electric screw driver 60 and rotary encoder 70 connect to form, mainly electric screw driver 60 rotates forward rotation after being energized, by bindiny mechanism's driven rotary encoder 70, after electric screw driver 60 is by screw lock, there will be stall stops phenomenon, now electric screw driver 60 can pass to relay 53 stall brake signal, so relay 53 can be connected to photoelectrical coupler 85 by NC by normally-closed contact, photoelectrical coupler 85 is connected into drive circuit CPU 20 by pin and carries out signal conversion, after receiving brake signal, by program, the coil of relay 52 is obtained electric normally closed, contact disconnects, enabling signal also disconnects simultaneously, and delay procedure (50m.s), after delay time completes, 51 relays export reversal voltage, then the power-off of program 52 relay coil is used, normally-closed contact conducting, thus provide enabling signal, bottle opener reversion rotarily drives rotary encoder 70 and starts counting.After counting down to setting value, rotary encoder 70 carries out signal conversion by drive circuit CPU 20, and make relay 53 conducting provide brake signal, electric screw driver 60 quits work.
As shown in Figure 6, be the control unit panel schematic diagram that application example of the present invention provides, below in conjunction with other accompanying drawings, the correlation function that it provides be described below:
1. power switch
Be mainly used to on-off circuit power supply.
2. status switch
When top got to by status switch, this switch can realize the state of reverse function, and when below got to by status switch, this switch can realize the state of positive rotating function.The namely present due functional switch of common electric bottle opener.Usually open when moment mainly measured by this switch and use, when intervening gears shifted onto by this switch, return to the function of the front electric screw driver of repacking exactly.
3. pinning height adjuster
Be mainly used to regulate pinning height, it is that (this is for product of the present invention, because different, sets according to individual required value for the height of 0.1mm that button often clicks.
4. pitch regulator
Because now conventional self threading pin thread spacing is a lot, select 5 the most frequently used thread spacing according to national standard according to different tapping screws to regulate, (1.1,1.3,1.4,1.6,1.8) mm respectively, select according to actual requirement, after the pitch of the self threading pin that selected good user uses, then be transferred to pinning height adjuster the height that user thinks pinning, such system will carry out pinning operation according to the requirement of user.
5. operating switch
After this switch is pressed, the automatic pinning of electric screw driver, realizes the repacking pinning function required.
6. rotary encoder
Rotary encoder is mainly used to turns counting pulse, is mainly arranged on screwdriver head, and after electric screw driver rotates, it realizes tally function.
7. encoder fixture
By fixed connecting piece, encoder is fixed to screwdriver head front end, the normal function of bottle opener Torque-adjusting and installation screwdriver head can not be affected while stationary state.
Application example bottle opener of the present invention attacks bottom lock-screw screw, then produces stall signal, after controller detects stall signal, sending reverse signal makes bottle opener reverse, driven rotary encoder starts counting simultaneously, when bottle opener forwards predetermined pulse number to, and bottle opener stall.Namely application example of the present invention realizes the preset height of user's pinning by umber of pulse and conversion highly.
