The utility model is the outer ring of stirring first freewheel clutch with straight-line plunger, makes the pulse straight-line displacement be converted into the outer ring angular displacement.Second freewheel clutch adds up the pulse angle displacement, carries out work by outer, the interior cone of friction output shaft output torque of being with the friction circle conical surface.The qualification of its moment of torsion then will be by adding the reaction torque device in advance.
The utility model is simple in structure, volume is little, cost is low.It has overcome tightening torque and has controlled inaccurate shortcoming, is that a kind of fastener installation tool of efficiently and accurately is turned round controlling organization surely.It can be widely used on fastener installation tool and Other Instruments, the equipment.
Below in conjunction with accompanying drawing the utility model is done further explanation.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the A-A cutaway view of Fig. 1.
Illustrated in figures 1 and 2, when compressed air or pressure oil or other medium entered the cylinder chamber 17 of housing 16, piston 2 moved to left and orders about external friction awl output shaft 3 and be frictionally engaged with taper seat 18 with interior cone of friction output shaft 10.Thereby the angular displacement of external friction awl output shaft 3 just can be by interior cone of friction output shaft 10 outputs.
Be installed in the plunger 1 that has annular groove 19 in the housing 16 and under the effect of intermittence external force P and back-moving spring 15, produce reciprocating motion (P power will enough overcome the reset force of back-moving spring 15), and make the outer ring 7 of first freewheel clutch 20 produce angular displacement by bearing pin 6.When plunger 1 was subjected to that intermittently external force P effect moves right, the left side promotion bearing pin 6 of the annular groove 19 of plunger 1 and the outer ring 7 that drives first freewheel clutch 20 clockwise rotated, and the interior circle of outer ring 7 forces needle roller 8 to revolve round the sun clockwise.Among the figure as can be seen the inner ring 9 of first freewheel clutch 20 do not change.Thereby also motionless with key 11 with the external friction awl output shaft 3 of its bonding, i.e. empty wagons.When power P disappeared outside the party, back-moving spring 15 forced plunger 1 to move to left, and the right side of annular groove 19 promotes bearing pin 6 return that moves to left, the outer ring 7 of first freewheel clutch 20 with then rotate counterclockwise.The inner ring 9 that needle roller 8 blocks first freewheel clutch 20 makes it and outer ring 7 same moved further.So external friction awl output shaft 3 also rotates counterclockwise an angular displacement synchronously.The rotation of external friction awl output shaft 3 drives the inner ring 5 same moved further of second freewheel clutch 21 again.Thereby first, second freewheel clutch 20 and 21 is to be provided with synchronously, this moment second freewheel clutch, 21 empty wagons, external friction awl output shaft 3 can rotate.Cone of friction output shaft 10 awl of external friction simultaneously output shaft 3 is passed to angular displacement by taper seat 18 in.Be installed with one between interior cone of friction output shaft 10 and the housing 16 and add reaction torque device 14 in advance, as torsion spring etc., as torque limiting mechanism.The size of reaction torque increases with the increase of interior cone of friction output shaft 10 angular displacements.The purpose of reaction torque is set, and is the angular displacement zero clearing with interior cone of friction output shaft 10.When the taper seat 18 of inside and outside cone of friction output shaft 10 and 3 was thrown off, interior cone of friction output shaft 10 was got back to the home position immediately under the reaction torque effect.
When intermittence, external force P occurred once more, plunger 1 moves to right again, and outer ring 7 clockwise rotates again, and needle roller 8 clockwise rotates, inner ring 9 is not worked, and at this moment interior cone of friction output shaft 10 will drive external frictions awl output shafts 3 by taper seat 18 and clockwise rotate under the reaction torque effect of reaction torque device 14.But, the outer ring 4 and the housing 16 of second freewheel clutch 21 are close to firmware 13 and are connected, the trend that external friction awl output shaft 3 drive inner rings 5 clockwise rotate is prevented from, external friction awl output shaft 3 can not clockwise rotate, the pulse angle displacement is just memorized, angular displacement is added up, and removes to drive fastener installation tool by interior cone of friction output shaft 10.Surely turning round control is then realized by reaction torque device 14.As long as in the each angular displacement of cone of friction output shaft 10 identical, the moment of torsion of transmission is also just identical.
When the acting pressure medium of piston 2 right-hand members disappears, inside and outside cone of friction output shaft 10 and 3 taper seat 18 are thrown off, and angular displacement just can not be exported by interior cone of friction output shaft 10.On the contrary, it gets back to original position under the effect that adds reaction torque in advance, prepares to carry out the output of angular displacement next time.
Present embodiment is made of housing 16, torque-transmitting mechanisms and torque limiting mechanism.Torque-transmitting mechanisms is by can being made of bearing pin 6, first freewheel clutch 20, second freewheel clutch 21, key 11, external friction awl output shaft 3, interior cone of friction output shaft 10, the piston 2 of plunger 1 swing in the annular groove 19 of plunger 1, back-moving spring 15, end insertion plunger 1.It is simple in structure, volume is little, the moment of torsion precise control, can be widely used in the fastener installation tool.
