The specific embodiment
With reference to Fig. 2, electric screwdriver 100 has housing 101, and in this housing, the motor (not shown) passes through gear-box 104 and the driving shaft (not shown), and this is positioned at the hole 102 of single-hook ring 103.Single-hook ring 103 can rotate with respect to housing 101, thereby adjusts peak torque (this peak torque can be delivered to the axle from motor) in the mode that below will describe in detail more, thereby therefore axle can make the screw threads commentaries on classics be driven in the workpiece (not shown).
Single-hook ring 103 is installed on the housing 101 at circumferential groove 105 places, therefore can prevent that single-hook ring from carrying out axially-movable with respect to housing 101.Single-hook ring 103 also is provided with a series of V-shaped generally otch 106, these otch, are fixed on the correct position at the groove 109 that is positioned at gear-box 104 outsides with respect to gear-box 104 by the formed elastomeric stopper 108 of the curved bel of elastic metallic on its rear surface 107 along circumferential directions.
Be shown specifically as Fig. 3 and 4, retainer 108 is provided with: be arranged on the center, be the protuberance 110 of V-arrangement generally; Reaching a pair of is straight arm 111 generally, and wherein each straight-arm is arranged on every side of protuberance 110.The elasticity of retainer 108 is such, with activation not holding in the groove 109 on gear-box 104 of arm 111 is held in place, simultaneously, when it is rotated with respect to gear-box 104, thereby protuberance 110 skews are disengaged with otch 106, thereby slip over the rear surface 107 of single-hook ring 103.These positions that retainer 108 engages otch 106 limit a series of positions that discharge moment of torsion of electric screwdriver 100, and these positions will be described below in further detail.
Now, with reference to Figure 4 and 5, the protuberance 112 that the inner surface of single-hook ring 103 has is axially extended, radially inwardly stretch out, these protuberances 112 are arranged in around the inner surface, these protuberances match with otch 113 axially extended, that radially inwardly stretch out accordingly, these otch 113 are positioned on the moment of torsion control loop 114, and this control loop has thread inner surface 115.Moment of torsion control loop 114 is installed in single-hook ring 103 inside, and has produced rotation owing to the protuberance on the single-hook ring 103 112 engages with otch 113 on the moment of torsion control loop 114, but moment of torsion control loop 114 also can axially-movable with respect to single-hook ring 103.
Now, with reference to Fig. 8, it is columniform main body 116 generally that the moment of torsion controlling organization of electric screwdriver 100 has, and this main body 116 is extended from gear-box 104, and have threaded portion 117 on the outer surface that surrounds axle 118, this axle 118 reaches in the hole 102.Threaded portion 117 is arranged to cooperate with the thread inner surface 115 of moment of torsion control loop 114, thereby when relatively it rotates with single-hook ring 103, makes moment of torsion control loop 114 carry out axially-movable along main body 116 at it.
With reference to Fig. 9 and 10, the clutch mechanism with clutch disc 119 be installed in towards with surround on end main body 116, gear-box 104.(work of this mechanism is known for those of ordinary skills to clutch mechanism, therefore be not described in detail) carry out work by this way, so that it allows to be transported to the axle 118 from gear-box 104 less than the moment of torsion of preset limit, but, if the moment of torsion that gear-box 104 is applied surpasses that limit, clutch engagement force is not enough to prevent that the axle 118 driving shaft (not shown) with respect to gear-box 104 are rotated so.
The work of the moment of torsion guiding mechanism of the electric screwdriver 100 shown in the accompanying drawing is described now.
In layout shown in Figure 2, single-hook ring 103 can rotate with respect to gear-box 104, but can not axially-movable with respect to gear-box 104.Engage by an otch 106 on the back 107 of the summit 110 that makes retainer 108 and single-hook ring 103, single-hook ring 103 is releasably remained on the suitable position of rotation with respect to gear-box 104.Consequently, because the protuberance 112 on single-hook ring 103 inside engages with otch 113 on moment of torsion control loop 114 outsides, the position of rotation of moment of torsion control loop 114 is fixed with respect to single-hook ring 103.Screw thread 115 on the inner surface of moment of torsion control loop 114 engages with threaded portion 117 on the outer surface of main body 116, and this has just determined the axial location of moment of torsion control loop 114 with respect to gear-box 104.This itself has just set the compression stress of compression spring 120, and this compression stress has been set clutch engagement force, has therefore set to be delivered to peak torque on the axle 118 from gear-box 104.
In order to adjust torque setting, single-hook ring 103 is rotated with respect to gear-box 104.This just makes retainer 108 carry out bending, and consequently the inclined surface owing to it makes its top area 110 and corresponding otch 108 throw off in the enterprising line slip of the respective surfaces of otch 106.Then, top area 110 slips over the rear surface 107 of single-hook ring 103, and when single-hook ring 103 was rotated with respect to gear-box 104, moment of torsion control loop 114 was forced to single-hook ring 103 rotations.Consequently, moment of torsion control loop 114 with respect to gear-box 104 along axially moving, thereby adjust the compression stress of compression spring 120, therefore adjusted and can be delivered to peak torque on the axle 118 from gear-box 104.When the top area 110 of retainer 108 arrived in the next otch 106 on the rear surface 107 of single-hook rings 103, by the elasticity of retainer 108, it was forced to engage with otch 106.When carrying out like this, elastomeric stopper 108 has produced audible card clatter one sound, thereby makes the user of electric screwdriver 100 know that single-hook ring 103 has engaged another torque setting.Then, single-hook ring 103 releasably remains on the correct position with respect to gear-box 104, and sets the compression stress of compression spring 120 with respect to the new axial location of gear-box 104 by moment of torsion control loop 114.
Those of ordinary skills will understand, more than just embodiment is described by means of the mode of example rather than with any restrictive one, and, under the prerequisite of the scope of the present invention that does not depart from claims regulation of enclosing, make various changes and modification is possible.
