The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Please refer to Fig. 1～7, the impact output mechanism of the utility model percussion drill, comprises moving impact disc 1, several roller 2, roller seat 3, roller fixed supports 4 for the moving impact disc 1 of conflicting.The moving sheathed turning cylinder 6 that is fixed on percussion drill of impact disc 1, makes turning cylinder 6 when rotating, and can drive moving impact disc 1 to rotate.Several rollers 2 are fixed on the front end of roller seat 3 by roller fixed support 4,, when impacting output, several rollers 2 of roller seat 3 front ends contact with moving impact disc 1.Roller seat 3 is sheathed on the turning cylinder 6 of percussion drill, and the function switching mechanism of roller seat 3 and percussion drill is in transmission connection, and (connected mode belongs to prior art, repeat no more) herein, when impacting output, the function switching mechanism of percussion drill can drive roller seat 3 to press forward, allow several rollers 2 of roller seat 3 front ends contact with moving impact disc 1, by moving impact disc 1 and several rollers 2, rub and produce vibratory impulse mutually.
Preferably, the rear end of moving impact disc 1 is provided with the waveform fluted disc 11 mating with several rollers 2, the form fit of the shape of each tooth of this waveform fluted disc 11 and roller 2, when several rollers 2 are contacted with the waveform fluted disc 11 of moving impact disc 1, because moving impact disc 1 is along with the rotation of turning cylinder 6 and the high low head between waveform fluted disc 11 and roller 2, the waveform fluted disc 11 of moving impact disc 1 can rub mutually with several rollers 2 and produce vibratory impulse.It is the principle of its vibratory impulse, identical with the impact output mechanism of existing percussion drill, but, the utility model adopts several rollers 2 to substitute the corrugated fluted disc of front end of quiet impact disc of the impact output mechanism of existing percussion drill, and due to the rolling characteristic of roller 2 self, thus make the waveform fluted disc 11 of impact disc 1 and the frictional force between several rollers 2 less, therefore, the noise that produces during impact is little, power saving, is also not easy wearing and tearing, more durable.Certainly, according to said structure, also can adopt several rollers to substitute the waveform fluted disc 11 of moving impact disc 1 rear end, such equivalent variations, all should belong to protection domain of the present utility model.
Preferably, the front end of roller seat 3 offers the roller slot position 31 of mating with roller 2, and the rear end of roller 2 is placed in roller slot position 31; Roller fixed support 4 offers the roller fixing hole 41 mating with roller 2, and the front end of roller 2 sees through roller fixing hole 41 and protrudes forward; The both sides of roller 2 are provided with roller card column 21, and the both sides of roller fixing hole 41 are raised with forward the lug boss 42 mating with roller card column 21, and the roller card column 21 of roller 2 both sides is connected in the lug boss 42 of roller fixing hole 41 both sides.Said structure, can make roller 2 connect and fix preferably, the friction in the time of can not affecting again roller 2 and contact with the waveform fluted disc 11 of moving impact disc 1.
