Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the stereo decomposing structural representation (part) of embodiments of the invention.
Detailed description of the invention
The following stated is only preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, as shown in Figure 1: multifunctional percussion drill, comprises that power set 12, percussion mechanism, electric drill impact conversion equipment and output shaft 2.Power set 12 can be motors.On output shaft 2, the cover of matched in clearance has gear wheel 8, and this gear wheel 8 is connected to power set 12.That is, power set 12 drive gear wheel 8 to rotate, and gear wheel 8 can drive output shaft 2 to rotate, and electric drill impacts conversion equipment electric drill and impact function are changed after, under the effect of percussion mechanism, output shaft 2 is in rotation, longitudinally vibration, thus impact function there is.
In order to expand the function of this percussion drill, this multifunctional percussion drill includes torsion adjusting device.Concrete, this torsion adjusting device comprises impact gear 10, torsion steel ball 9, lower platen 7, torque spring 5.Wherein, on this, impact gear 10 right sides are provided with salient point 101, and torsion steel ball 9 and this salient point 101 match., torsion steel ball 9 is pressed in the gap between salient point 101.Now, torsion steel ball 9 is accepted the pressure of torque spring 5 by lower platen 7.Certainly, the pressure of torque spring 5 from right to left, has torsion steel ball 9 and is pressed in the potential energy in space between salient point 101 left.Meanwhile, upper impact gear 10 and output shaft 2 interference fit, gear wheel 8 is provided with torsion transfer hole 81, and torsion steel ball 9 is positioned at this torsion transfer hole 81.Like this, under the effect of torque spring 5, torsion steel ball 9 is not in the time that the load of output shaft 2 reaches setting value, torsion steel ball 9 can not jumped out in the gap between salient point 101, thereby after gear wheel 8 rotations, torsion steel ball 9, along the axial line rotation of output shaft 2, impacts gear 10 and rotate, and then output shaft 2 rotates in drive.After the load of output shaft 2 exceedes setting value, torsion steel ball 9 can be jumped out the gap between salient point 101 to the right, thereby produces and skid between torsion steel ball 9 and upper impact gear 10, and then makes output shaft 2 cannot continue rotation.In sum, output shaft 2 has had the upper limit of output torque value, thereby has had the function that torsion bores.
Optimize, torsion adjusting device also comprises that torsion pressing plate 4 and rotatable power are turned round and covers 1.Such as power is turned round and covered 1 and can longitudinally be articulated on the casing of multifunctional percussion drill, thereby under external force turn, can be rotated.Wherein, power is turned round to cover in 1 and is provided with at least 2 steps, and this step and torsion pressing plate 4 match, and the right-hand member of torque spring 5 withstands on the left side of torsion pressing plate 4., torsion pressing plate 4 can coordinate with different steps, makes torsion pressing plate 4 on left and right directions, have different positions, thereby makes torque spring 5 have different initial pressures.Like this, torsion steel ball 9 has had the different potential energy that holds out against left.Obviously, it is larger that what torsion steel ball 9 had hold out against potential energy, and torsion steel ball 9 is difficult to jump out in the gap between salient point 101 further, and then makes 2 moments of torsion that can export of output shaft larger, and 2 loads that can carry of this output shaft are larger.In sum, power is turned round the rotation of covering 1, has adjusted the load value that output shaft 2 can bear.And power is turned round the quantity of covering 1 interior step and is the gear of the load value of output shaft 2.Such as, step can be 8 grades of steps, output shaft 2 had both had 8 stage load bearing values.
Obviously,, when multifunctional percussion drill is in the time that torsion bores function, this multifunctional percussion drill can not be in impact conditions.
Further, this multifunctional percussion drill includes the torsion electric drill conversion equipment that bores function for changing electric drill function and torsion.Concrete, this torsion electric drill conversion equipment is: 4 interlocks of torsion pressing plate have gearshift lower cover 6, and these gearshift lower cover 6 right sides are provided with lower cover projection 61, and gearshift lower cover 6 right sides are provided with non-rotatable gearshift upper cover 3.Wherein, the mode of torsion pressing plate 4 interlock gearshift lower covers 6 can be: torsion pressing plate 4 axle center places are provided with groove, gearshift lower cover 6 outer surfaces are provided with the fin matching with groove.Like this, after 4 rotations of torsion pressing plate, gearshift lower cover 6 synchronous rotaries, and gearshift lower cover 6 can left and right displacement.These gearshift upper cover 3 left sides are provided with upper cover projection 31, and this upper cover projection 31 and lower cover projection 61 match.,, in the time that the peak of upper cover projection 31 and lower cover projection 61 pushes up mutually, gearshift lower cover 6 and gearshift upper cover 3 have maximum distance; In upper cover projection 31 withstands on the gap between lower cover projection 61 time, gearshift lower cover 6 and gearshift upper cover 3 have minimum distance.Meanwhile, the left end of this gearshift lower cover 6 holds out against lower platen 7.That is, gearshift lower cover 6 and the distance of gearshift between upper cover 3 have determined the position of lower platen 7 on left and right directions: when gearshift lower cover 6 and gearshift upper cover 3 have maximum distance, lower platen 7 is in relative high order end, thereby without mobile space; When gearshift lower cover 6 and gearshift upper cover 3 have minimum distance, lower platen 7 is in relative low order end, thereby has mobile space.Like this, by suitable adjustment, make lower platen 7 when without mobile space, lower platen 7 can limit torsion steel ball 9 and jump out in the gap between salient point 101, make output shaft 2 no longer there is torsion setting and regulatory function, thereby output shaft 2 only can carry out electric drill or impact operation.
Percussion mechanism can be taked multiple common mode, and it is for making output shaft 2 produce longitudinal vibration, thereby makes output shaft 2 have impact function.Optimize, this percussion mechanism is that upper impact gear 10 left sides are provided with passive double wedge; On this, impact gear 10 left sides are provided with lower impact gear 11, and these lower impact gear 11 right sides are provided with initiatively double wedge, and this active double wedge and passive double wedge match., initiatively double wedge and passive double wedge, after the contacting of rotation status, can make the longitudinal vibration of output shaft 2 and form impulsive force.
Certainly, electric drill impacts conversion equipment for changing electric drill function and the impact function of this multifunctional percussion drill, and it can take multiple common mode.Optimize, this electric drill impacts conversion equipment and comprises gearshift assembly 13.This gearshift assembly 13 is provided with limiting plate 131, and has through hole 1311 on limiting plate 131, and this limiting plate 131 withstands on the left end of output shaft 2.Like this, in the time that output shaft 2 withstands on limiting plate 131, upper impact gear 10 separates with lower impact gear 11, thereby cannot produce impulsive force; When output shaft 2 withstands on through hole 1311 on limiting plate 131 when interior, upper impact gear 10 contacts with lower impact gear 11, thereby produces impulsive force.
Percussion drill is widely used at present, and other structure and principle are same as the prior art, repeat no more here.
