It is provided with together or twice positioning step or for installing the groove 13 of shaft block ring outside screwdriver bit guide rod.
The electromagnetic levitation type scalable screwdriver bit assembly for screw tightening of the present invention, can be to various ironys or steel screw
Carry out drawing and righting, and self-adapting stretching floating can be carried out when contacting feeding machanism and workpiece.Magnetic for screw tightening
Floated screwdriver bit assembly, by magnet iron piece 2(embedded magnet 1), screwdriver bit the 3rd, back-moving spring the 4th, screwdriver bit guide rod the 7th, alignment pin the 5th, guide the 6th,
Buffer Unit the 8th, lifting spring the 9th, spring thrust ring the 10th, thrust pins 11 etc. form.By screwdriver bit guide rod 7 and magnet iron piece 2 cooperation position
It is designed to cylinder, middle processing bar-shaped trough, is guided by an alignment pin 5, by rational tolerance fit, ensureing
Screwdriver bit guide rod 7 and magnet iron piece 2 be slidably matched and run up axiality while, by backing off, the 6th, guide ejects alignment pin 5
After, also can change screwdriver bit 3 faster.Note: the non-magnetic screws such as stainless steel, copper, aluminium, plastics are not suitable for this screwdriver bit assembly.
Comprising magnet 1 in magnet iron piece 2, magnet 1 can be mounted to one end of magnet iron piece 2 interiorly or exteriorly, it is also possible to inlays
Middle part to magnet pieces 2.Magnet iron piece 2 arranges a hole at magnet 1 one end position, in order to adjust position in magnet iron piece 2 for the magnet 1
Put.
The effect low suspension of screwdriver bit 3 magnetic force in magnet iron piece 2 is in magnet iron piece 2, with one between magnet iron piece 2 and screwdriver bit guide rod 7
Individual back-moving spring 4 and an alignment pin 5 connect, and alignment pin 5 plays guiding and anticreep effect.Alignment pin 5 is outside guide 6, prevents
Alignment pin 5 moves and comes off.
The shape of screwdriver bit guide rod 7 and driving means output shaft contact site have in-line, cross, rectangle, square, six
Dihedral, ellipse, centre can carry circular cone to import axle.
Screwdriver bit guide rod 7 is outside to be provided with together or twice positioning step or for installing the groove of shaft block ring, with driving means
That end of contact is provided with pin-and-hole, and there are lifting spring 9 and the spring thrust ring 10 preventing thrust pin 11 from coming off in outside.Screwdriver bit guide rod 7
Middle part play the Buffer Unit 8 of cushioning effect when being provided with reset, reduce noise and the impact to rotary disc assembly.
Lifting spring 9 outside screwdriver bit guide rod 7 and the back-moving spring 4 within magnet iron piece 2 all play reset role.
The present invention is realized by following operation principle:
Screwdriver bit 3 leads to the magnet 1 in magnet iron piece 2 and realizes suspending, and when drawing screw, screwdriver bit 3 can suit with screw automatically, and
Under the effect of magnetic force, righting is carried out to screw.
During pickup: when this screwdriver bit component touch multiple concentrating in together is for spike devices, magnet iron piece 2 contacts screw top
And hold, according to the height of screw, each screwdriver bit assembly is retracted corresponding distance automatically, makes each screwdriver bit assembly all close with screw
In conjunction with completing the absorption to screw under the effect of magnet 1.
When lock is paid: when driving means makes screw and absorption surface, screw promotes magnet iron piece 2 to return, screwdriver bit guide rod 7 and magnetic
Ironware 2 produces relative displacement, the in-line of profiling groove in screwdriver bit guide rod 7 contact screwdriver bit 3 afterbody or other symmetric shapes
Empennage, enters certain depth and rotates together, screw is screwed into workpiece.When be screwed into complete driving means return when, at reset bullet
The effect lower magnet part 2 of spring 4 resets, and screwdriver bit guide rod 7 separates with screwdriver bit 3, and screwdriver bit 3 becomes free suspended state, can be along screwdriver bit 3 axle
Freely stretch in line direction.
