Fig. 2 is the another kind of structural representation of the slewing limit mechanism that provides of the utility model embodiment;
Fig. 3 is a kind of concrete structural representation of the movable limited part in the slewing limit mechanism that provides of the utility model embodiment.
Embodiment
The utility model provides a kind of slewing limit mechanism, below in conjunction with accompanying drawing, the utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the utility model, does not limit the utility model.
As shown in Figure 1, embodiment of the present utility model provides a kind of slewing limit mechanism, comprises the fixing limited part 11 being arranged on turntable 1 and is arranged on the movable limited part 21 on base 2, and turntable 1 and base 2 are by the rotatable connection of rotating shaft 3; After movable limited part 21 is subject to fixing limited part 11 and clashes into, the circumferential direction of rotating along turntable 1 is with respect to base 2 predetermined angular that moves.
The slewing limit mechanism that the utility model provides, comprise the fixing limited part 11 being arranged on turntable 1 and be arranged on the movable limited part 21 on base 2, when turntable 13 rotates and reaches need to limit bit position time with respect to base 2 around the shaft, the fixing limited part 11 being positioned on turntable 1 can bump against with the movable limited part 21 on base 2.After movable limited part 21 is subject to fixing limited part 11 and clashes into, the circumferential direction that can rotate along turntable 1 is with respect to base 2 predetermined angular that moves.Like this, after fixing limited part 11 and 21 collisions of movable limited part, can't stop at once, but together with movable limited part 21 along circumferential direction with respect to base 2 predetermined angular that moves, as long as this chooses suitable predetermined angular, the motion of movable limited part 21 on base 2 can make the turntable 1 can be by the effectively spacing rotation that can realize again 360 °, thereby effectively improved the performance of equipment.
Particularly, when being subject to after the shock of fixing limited part 11, movable limited part 21 can move along circumferential direction with respect to base 2, and this can realize by kinds of schemes.For example, as shown in Figure 2, in an embodiment of the present utility model, on base 2, be provided with arc groove 22 along circumferential direction, movable limited part 21 is slidably disposed in arc groove 22.Like this, when turntable 1 rotates around rotating shaft 3 and when a side of the movable limited part 21 on fixing limited part 11 and base 2 is bumped against, movable limited part 21 segment distance that will slide in arc groove 22, until bump against the movable opposite side of limited part 21 and one end of arc groove 22, movable limited part 21 after collision starts to counter-rotation clashing under the effect of reaction force, until turntable 1 finally stops or bumping against with the opposite side of movable limited part 21 after stop.Certainly, also can on the surface of turntable 1, arc groove 22 be set, and replace this arc groove 22 with the protruding track of arc, as long as can make movable limited part 21 can rotate with respect to turntable 1 in the time standing the shock of fixing limited part 22.
In the present embodiment, for make turntable 1 can carry out 360 ° or exceed 360 ° rotate and unrestricted, arranging of arc groove 22 need to meet certain requirement, optional, can increase by increasing the sliding scale of movable limited part 21 in arc groove 22 rotation angle of turntable 1.For example, the length along circumferential direction of movable limited part 21 is less than or equal to the half of the length along circumferential direction of arc groove 22.
Particularly; as shown in Figure 3; movable limited part 21 can comprise slide block 211, and in order to accelerate spacing to turntable 1, simultaneously also for protection equipment is avoided damage in collision; preferably; movable limited part 21 also comprises buffer stopper 212, as rubber absorbers etc., and the surface of bumping against with fixing limited part 11 that buffer stopper 212 is arranged on slide block 211; for example can be fixed on the respective surfaces of slide block 211 by stickup or screw, clash into thereby can absorb the portion of energy producing.
The slip of movable limited part 21 in arc groove 22 inevitably can produce surface friction drag, in order to reduce the wearing and tearing of surface friction drag to device, optionally, in arc groove 22, can also be provided with slide rail, movable limited part 21 along slide rail slidably, because slide rail 22 is less with the area of contact of movable limited part 21, therefore force of sliding friction is between the two also relatively little, thereby can effectively reduce the wearing and tearing of device.
Optionally, between the circumferential side wall of arc groove 22 and movable limited part 21, can also be provided with ball, movable limited part 21 can be by ball in the interior slip of arc groove 22.
Accordingly, embodiment of the present utility model also provides a kind of rotation motion equipment, and any slewing limit mechanism providing in previous embodiment is provided on this rotation motion equipment, therefore also can realize corresponding useful technique effect, have been described in detail above, repeat no more herein.
Although be example object, preferred embodiment of the present utility model is disclosed, it is also possible those skilled in the art will recognize various improvement, increase and replacement, therefore, scope of the present utility model should be not limited to above-described embodiment.
