Detailed description of the invention
Below in conjunction with Fig. 1 ~ 3, describe content of the present utility model in detail by specific embodiment.This pinion and-rack reciprocating impact device comprises housing, be arranged on the tooth bar assembly in housing and the part such as the partial gear being positioned at tooth bar assembly.Wherein, tooth bar assembly 2 comprises oval loop configuration and is arranged on the impact slide block 2-2 of loop configuration length direction one end, the outer rim of impacting slide block 2-2 matches with housing 1 inwall, and the length direction of loop configuration inwall is respectively equipped with tooth bar, and loop configuration outer wall is provided with flange 2-1.Flange 2-1 adds the intensity of tooth bar assembly 2, ensures that tooth bar assembly 2 reciprocatingly slides along the chute 1-2 offered in housing 1 simultaneously, play the guiding role.Impact slide block 2-2 far-end semicircle (the semicircle 2-3 of left end) the inwall radius of tooth bar assembly 2 is slightly larger than partial gear 3 root radius, near-end semicircle (the semicircle 2-4 of right-hand member) the inwall radius impacting slide block equals the root radius of partial gear 3, the end gear teeth (nibbling out tooth 3-1, engaging-in tooth 3-2) of partial gear 3 are fillet, and when preventing tooth bar assembly 2 from commutating, upper and lower latch phenomenon appears in gear, tooth bar.Partial gear 3 can by the driving such as motor, decelerator.Housing 1 inwall is provided with the chute 1-2 matched with tooth bar assembly 2 flange, housing is provided with oilhole 1-1, and the impact slider end in housing is spacing beater mechanism, and housing 2 inwall is fixedly pasted with rubber blanket 5, rubber blanket 5, for beater mechanism 4 provides certain screen resilience.The rotating shaft of partial gear 3 is spacing on housing 1, the gear teeth of partial gear 3 engage with a wherein tooth bar of tooth bar assembly 2, driving gear bar assembly 2 moves back and forth, the tooth number of partial gear 3 is less than full-depth tooth number half, with ensure tooth bar assembly 2 and quadrant tooth depart from every turn engage after have one section of free inertia motion, collision impact beater mechanism 4 in this movement travel.Screw thread mounting nuts 4-1 on beater mechanism 4, nut 4-1 controls the distance of beater mechanism 4 resilience when impacting rebound is strong, make the collision of tooth bar assembly 2 and beater mechanism 4 still occur in the freely-movable stroke of tooth bar assembly 2, the impact head link 4-2 of beater mechanism 4 can install different impact heads and rotating mechanism according to different demands.
The course of work:
In Fig. 2 (a), the upside gear teeth meshing of partial gear 3 and tooth bar assembly 2, partial gear 3 rotates clockwise band carry-over bar assembly 2 right lateral, now beater mechanism 4 is in the resilience stage, along with the carrying out of motion, in Fig. 3, tooth bar assembly 2 departs from partial gear 3 and engages, now due to fewer than half full-depth tooth number of partial gear 3 number of teeth, and tooth bar assembly left end semicircular inner walls 2-3 radius is slightly larger than partial gear 3 root radius, tooth bar assembly 2 is made to have a bit of free inertia motion stroke to the right;
In Fig. 2 (b), the impact slide block 2-2 of tooth bar assembly 2 and the beater mechanism 4 of resilience collide, and beater mechanism 4 obtains enormous impact power to the right, are subject to the reverse bounce of beater mechanism 4 with hour rack assembly 2;
In Fig. 2 (c), beater mechanism 4 promotes impact head 7 to the right, tooth bar assembly 2 under bounce effect to left movement, the gear teeth and the gear teeth meshing of partial gear 3 rotated clockwise on the downside of tooth bar assembly 2, the backhaul of tooth bar assembly 2 left lateral;
In Fig. 2 (d), along with the carrying out of motion, tooth bar assembly 2 and partial gear 3 out-of-gear moment, because tooth bar assembly 2 right-hand member semicircular inner walls 2-4 radius equals partial gear 3 root radius, now semicircular inner walls 2-4 and partial gear 3 contact-impact, force tooth bar assembly 2 to stop left lateral, subsequently gear teeth meshing on the upside of the gear teeth of partial gear 3 and tooth bar assembly 2, and then band carry-over bar assembly 2 right lateral, carry out the motion of next circulation.
