[specific embodiment]
Below in conjunction with the description of drawings and the specific embodiment the utility model is further specified.
As shown in Figure 1 to Figure 3, a kind of continuous hammer mechanism, this continuous hammer mechanism comprises driving mechanism 11, cylinder body 12, piston 13, energy-storaging spring 14, jump bit 15, guide pin bushing 17 and impulse pin 18; Driving mechanism 11 links to each other with piston 13, is being with piston 13 relative cylinder bodies 12 to move back and forth; Piston 13 is placed in the plunger shaft 122 of cylinder body 12; Piston 13 comprises closed end 134, cavity 131 and an openend 132, jump bit 15 is placed in the cavity 131, this jump bit 15 can move back and forth in cavity 131, and energy-storaging spring 14 also is placed in the cavity 131 and an end and closed end 134 joins, the other end and jump bit 15 join; Guide pin bushing 17 is fixed in the cylinder body 12, and guide pin bushing 17 is socketed on impulse pin 18, impulse pin 18 move back and forth direction and jump bit 15 to move back and forth direction identical.
Openend 132 is provided with a screens groove 133; This continuous hammer mechanism comprises a screens spring 16, screens spring 16 parts are embedded at screens groove 133, in the cavity 131 of piston 13, this structure has following effect by energy-storaging spring 14 and screens spring 16 relative positionings for jump bit 15: the one, and can offset jump bit 15 and move back and forth the inertia force that brings; The 2nd, when impulse pin 18 dieback jump bits 15, energy-storaging spring 14 distortion avoid the power sources such as motor of driving mechanism 11 stuck, thereby finish the function of bump; The 3rd, jump bit 15 and piston 13, the sealing between piston 13 and the cylinder body 12 does not require, and cuts down finished cost greatly, has avoided the trouble of bringing owing to seal failure.Impulse pin 18 comprises a boss 181; Cylinder body 12 comprises a spacing reducing 121, is a cavity between spacing reducing 121 and the guide pin bushing 17, and boss 181 is positioned at this cavity.Linking to each other with boss 181 is provided with a back-moving spring 20, and back-moving spring 20 is sheathed on impulse pin 18.One end of back-moving spring 20 links to each other with the end face of guide pin bushing 17, the other end links to each other with the end face of boss 181, because impulse pin 18 is close to a back-moving spring 20, so impact and the non-impact conditions of impulse pin 18 also changed when the state of back-moving spring 20 changed, promptly can realize easily that in impulse pin 18 clutch of impacting with non-impact changes by executing external force.When needs impact, by external force impulse pin 18 is compressed into and to be got final product, and along with the size of the different impulsive forces of pressure size is also different.
The operation principle of the continuous hammer mechanism of the utility model is:
Piston 13 is driven in plunger shaft 122 by driving mechanism 11 and moves back and forth, and when driving mechanism 11 brought to piston 13 away from impulse pin 18, jump bit 15 was spacing down also away from impulse pin 18 energy-storaging spring 14 and screens spring 16; Driving mechanism 11 brings to piston 13 when the impulse pin 18, and jump bit 15 is spacing down also near impulse pin 18 energy-storaging spring 14 and screens spring 16, and near the time have speed.
When impulse pin 18 was not subjected to external force, this impulse pin 18 had certain reservation distance with jump bit 15 under the effect of back-moving spring 20, even jump bit 15 is near also impacting less than impulse pin 18, at this moment, jump bit 15 is in disengaged position with impulse pin 18.
When impulse pin 18 was subjected to external force near jump bit 15, jump bit 15 promptly produced impact near impulse pin 18.
If it is bigger that impulse pin 18 is stressed, then impulse pin 18 is just bigger towards the distance that jump bit 15 slides, the outside impulsive force of jump bit 15 impact pins 18 is just big more, when the suffered pressure of impulse pin 18 is enough big, piston 13 continues to move to impulse pin 18 under the drive of driving mechanism 11, at this moment jump bit 15 can not travel forward under the stopping of impulse pin 18, piston 13 is with compress energy storage spring 14, when piston 13 moves to the precalculated position, piston 13 is motion in the opposite direction under the effect of driving mechanism 11, finish one-shot this moment, driving mechanism 11 promotes piston 13 continuously and moves back and forth, thereby finishes the function of bump.
Continuous hammer mechanism of the present utility model can be finished the function of nailing as ailing machine at impulse pin 18 fronts nail of placement during use; Can place drill hammer in impulse pin 18 fronts and get final product as jump bit 15.Driving mechanism 11 its power sources of the present utility model can adopt knows the multiple mode of knowing, comprises electronic and pneumatic.
The utility model adopts between jump bit 15 and the closed end 134 energy-storaging spring 14 is set, and realizes continuous hammering, the use of cancellation heat resistant and wear resistant sealing ring 22, thereby the accuracy of manufacture of reduction part.Adopt on the impulse pin 18 boss 181 is set, linking to each other with boss 181 is provided with a back-moving spring 20, thereby rationally regulates the contact position of impulse pin 18 and jump bit 15, to change the impulsive force size, and under the reset mode, impulse pin 18 is realized discontinuous hammering away from jump bit 15.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
