Specific implementation mode
A kind of tapping auxiliary device based on magnetic rheology effect, the easy device include windeisen (3), spanner geometrical clamp
(4), cylinder roller bearing (7), piston (6), cylindrical drum (5), pedestal (12), screw tap (10), O-ring seal (8), compressed spring
(11), permanent magnet (9), magnetorheological fluid (13), coil admission extinguisher (2) and electromagnetic coil (1).The windeisen (3) is fixed
In on spanner geometrical clamp (4), it is therefore an objective to provide effective tapping flywheel moment.The spanner geometrical clamp (4) is collar plate shape,
Upper surface is equipped with groove, is used for positioning and clamping windeisen (3), and lower end is interference fitted with cylinder roller bearing (7).It is described
The shaft shoulder of cylinder roller bearing (7) and piston (6) be interference fitted.The piston (6) is revolving body, and the upper end is equipped with axis
Shoulder, lower end are disc structure, are provided with 4 circular troughs, for installing fixing permanent magnet (9)；Its lower end disc wall surface is provided with 6 half
Circular through hole, the flow channel as magnetorheological fluid (13).The compressed spring (11) has 4 altogether, and both ends are fixed respectively
In piston (6) disk and pedestal (12) it is upper, it is therefore an objective to provide piston (6) upward restoring force.The O-ring seal
(8) one 2, respectively in the groove of stator cylindrical drum (5) and piston (6), it is therefore an objective to keep to the close of magnetorheological fluid (13)
Envelope, prevents from leaking in the course of work.The cylindrical drum (5) and pedestal (12) is connected through a screw thread fixation.Described is magnetorheological
Liquid (13) is filled in the confined space that cylindrical drum (5), pedestal (12), piston (6) and O-ring seal (8) are formed.The coil
Admission extinguisher (2) is fixed in cylindrical drum (5) outside wall surface.The electromagnetic coil (1) is wound in coil admission extinguisher (2).
The concrete operating principle and implementation process of apparatus of the present invention be：It is used for controlling magnetorheological fluid (13) rheology in the present apparatus
The magnetic field of performance is mainly to be generated by electromagnetic induction, that is, permanent magnet (9) the cutting electromagnetic coil being fixed on piston (6)
(1), so that electromagnetic coil (1) is generated induced current, and then form powerful magnetic field.Compare permanent magnet (9) the faint magnetic of itself
, which has many advantages, such as that magnetic field intensity is big, is evenly distributed, and can implement completely to the rheological characteristic of magnetorheological fluid (13)
Regulation and control.When flywheel moment balance is when acting on windeisen (3), screw tap (10) remains vertical machining posture；By
Fail induction in electromagnetic coil (1) and generate magnetic field, magnetorheological fluid (13) at this time still keeps good mobile performance, therefore screw tap
(10) screw thread can be smoothly processed downwards.When acting on the flywheel moment imbalance on windeisen (3), piston (6) and silk
(10) while run-off the straight are bored, due to electromagnetic induction effect, the acceleration that piston (6) generates when tilting so that permanent magnet (9) is fast
Fast cutting electromagnetic coil (1) downwards, makes electromagnetic coil (1) instantaneously generate powerful induced current, and then generate powerful magnetic field.
Based on the rheological effect of magnetorheological fluid (13), magnetorheological fluid (13) at this time is instantaneously changed into class by liquid under the influence of a magnetic field
Solid state, and then prevent piston (6) that further tilt occurs.When the banking motion of piston (6) is in magnetorheological fluid (13)
When tending to be static under effect, i.e., piston (6) does not have tilt acceleration, and permanent magnet (9) at this time is opposite fast with electromagnetic coil (1) nothing
The dissection of speed, therefore electromagnetic coil (1) is without induced current and induced field generation, magnetorheological fluid (13) and by class solid-like
State is restored to liquid condition, keeps good mobile performance.At this moment inclined piston (6) is in compressed spring (11) elastic-restoring force
Under the action of restore balance again so that inclined screw tap (10) is also corrected, and original vertical machining state is kept.This
When, screw tap (10) and it can continue to process screw thread downwards, until completing screw thread process.
