Property particle 26 be magnetic material, such as magnet grains can be in this suspension of shear thickening liquid, and magnet grains etc. can be formed
Divide and suspends.
As shown in figure 3, by the way of the power supply of the two interval, opening A when control A group electromagnet 15 and B group electromagnet 25
Group electromagnet 15, then A group electromagnet 15 generates rapidly magnetic, attracts magnetic-particle 26 to move to A group electromagnet 15, then cuts off
The power supply of A group electromagnet 15 is powered B group electromagnet 25, then 26 stress of magnetic-particle is moved to B group electromagnet, so
Back and forth, quickly commutation, realizes vibration at high speed.
As shown in figures 1,4 and 5, when being installed to bolt it is last tighten or most start when dismantling when unscrewing, need
Biggish torque is provided, is exerted a force at this time by handle 1, remaining can drive rotation by the rotation of motor 27.To tighten clockwise
For, motor 27 is first turned on, drives driving gear 12 to rotate counterclockwise, is engaged with master control gear 4, drives master control gear 4 suitable
Rotation is transferred to bolt by elastomeric bladder 16, bolt rotation is driven to tighten, at this time by the side of 9 lower parts of control lock by hour hands rotation
Position it is found that master control gear 4 rotation, drive inclined surface that control lock will be made 9 to move up, control lock 9 will not stop master control gear 4
It actively rotates clockwise, after turning to a certain degree, when need to apply large torque, closes motor 27, left and right slight oscillatory handle
1, slide positioning shell 3 in the guide groove 5 of master control gear 4, the effect of pressure under control 9 self gravitys of lock or application
Under, make then to apply the power rotated clockwise in the spliced eye 8 below 9 insertion of control lock to handle 1 manually, be transmitted to positioning
Shell 3, by the connection at control lock 9, control 9 vertical planes of lock drive master control gear 4 to continue to rotate clockwise, by what is applied manually
Large torque is transmitted on bolt, completes to tighten.Control lock 9 can be transition fit or clearance fit with through-hole 7.
When needing to unscrew counterclockwise, 10 1 hundred 80 degree of swivel plate are rotated, control lock 9 is made to exchange the orientation of inclined surface,
Motor 27 inverts, remaining Principle of Process is same as above, and suitably operate.
Motor 27 and control lock 9 can do two groups of settings of bilateral symmetry.
As shown in Figure 6,7, handle 1 can realize the force control in a variety of orientation after rotation, and the setting of rubber strip 18 can mention
The hand-held comfort of height.
Hexagon socket head cap screw etc. is common connector, and is the lesser interior hexagonal of specification in, on handle 1
The lower part for the hexagon prism 20 being coupled can be adapted to several regular sizes of hexagon socket head cap screw, be easy to use, hexagon prism
20 tops are greater than lower part, can slide up and down in hexagon ring 19, and the lower part of hexagon prism 20 is made to expose and cooperate with interior hexagonal, rotation
Handle 1 provides torque.The use of sizing fixing device can be reduced, it is energy saving, or make up to the connector of specification very little
Applicability.
It when encountering the word or plus screw of oval head, is operated using fixed plate 23,21 sets of sleeve joint hole is existed
On the outside of screw, push fixed plate 23, make in a word cutter head 24 insertion screw, rotating handle 1 can applied force, a word cutter head 24 is right
Minus screw and plus screw have adaptability.
