The specific embodiment

See also Fig. 1 to Fig. 3, the aseismatic mechanism 20 of the bar feeder 10 that the utility model one preferred embodiment is provided includes two locating wheels 30, two driving wheels 40, second wheel group 50, a drive unit 60, a housing 70, and a bearing 80.

Respectively this locating wheel 30 is axis hole 32 and the three arc grooves 34 with break-through both sides, this axis hole 32 is to use for a bar to place, respectively this arc groove 34 is that the axle center with this axis hole 32 is the center of circle and arranging in the form of a ring, respectively the front end 341 of this arc groove 34 to the distance of these axis hole 32 perisporiums greater than the rear end 342 of this arc groove 34 respectively distance to these axis hole 32 perisporiums, make the center of circle of this arc groove 34 respectively be eccentric in the center of circle of this axis hole 32.

Respectively the outer peripheral face of this driving wheel 40 has a circular tooth part 42, and what respectively this driving wheel 40 had the perforation 44 of break-through both sides and three general ovalizes wears groove 46, the axle center of this perforation 44 is the axle center corresponding to this axis hole 32, use for this bar and place, respectively this to wear groove 46 be that axle center with this perforation 44 is the center of circle and arranging in the form of a ring, and respectively this wears groove 46 corresponding to this arc groove 34 respectively, in addition, be provided with a distance piece 48 between this two driving wheel 40, this distance piece 48 has the elongated slot 482 of a circular hole 481 and three general ovalizes, the axle center of this circular hole 481 is corresponding to the axle center of this axis hole 32 with this perforation 44, and respectively this elongated slot 482 is then corresponding to this arc groove 34 respectively and respectively this wears groove 46.

Respectively this roller set 50 be have that three rollers 52 and are arranged in this roller 52 respectively wear axle 54, this roller 52 is to be installed in respectively this locating wheel 30 and respectively between this driving wheel 40, respectively this wear the axle 54 be pass respectively this two locating wheel 30 respectively this arc groove 34, this two driving wheel 40 respectively this wears groove 46, and respectively this elongated slot 482 of this distance piece 48, and respectively this is worn in the arc groove 34 that axle two ends of 54 are embedded at this locating wheel 30 respectively respectively.

This drive unit 60 is to be pneumatic cylinder in the present embodiment, this pneumatic cylinder is to have a gear 62, this gear 62 is engageable circular tooth parts 42 in this driving wheel 40, this driving wheel 40 rotates in order to drive respectively, by by the respectively rotation of this driving wheel 40, respectively this to wear axle 54 be can be in slippage in this arc groove 34 respectively, make this roller 52 can with respect to the axle center of this driving wheel 40 respectively away from or close.

This housing 70 be for metal material made, it generally is cylindric, and inside has a room 72, can be in order to hold this locating wheel 30, this driving wheel 40, and this roller set 50, to avoid this locating wheel 30, this driving wheel 40, and this roller set 52 is subjected to improper external force and damages, in addition, the periphery of this housing 70 has most flutings 74, the circular tooth part 42 of this driving wheel 40 is to make the gear 62 of this drive unit pneumatic cylinder 60 can be engaged in the circular tooth part 42 of this driving wheel 40 through this fluting 74 by outside being revealed in by this fluting 74.

Please cooperate again and consult Fig. 4, this bearing 80 is made by metal material, it has the side plate 82 that a base plate 81 and two is fixed in these base plate 81 both sides respectively, by forming an accommodation space 83 with this two side plate 82 by this base plate 81, this housing 70 is bearable in this accommodation space 83, and the two ends of this housing 70 are connected to two side plates 82 of this bearing 80 respectively, in addition, be equiped with most protection pads 84 between the base plate 81 of this bearing 80 and this bar feeder 10, be locked on this protection pad 84 by passing this base plate 81 by most fixtures 85 screw as shown in the figure, make this bearing 80 be fixed in this bar feeder 10, this protection pad 84 is the shock-proof effects that can provide this aseismatic mechanism 20 better.

By by above-mentioned aseismatic mechanism 20, when the user sends a larger-diameter bar into this bar feeder 10, must utilize the gear 62 of this drive unit pneumatic cylinder 60 to rotate earlier to drive this driving wheel 40, when this driving wheel 40 produces anti-clockwise rotation, respectively this to wear axle 54 be to slide onto the respectively front end 341 of this arc groove 34, because respectively the front end 341 of this arc groove 34 is than the perisporium away from this axis hole 32, make this roller 52 will be away from the axle center of this axis hole 32, as shown in Figure 5, so that respectively the spacing between this roller 52 is bigger, can be in order to the larger-diameter bar of clamping; When the user sends into this bar feeder 10 with one than the bar of minor diameter again, must utilize this drive unit pneumatic cylinder 60 with respectively these driving wheel 40 generation rotations clockwise of control equally earlier, at this moment, respectively this to wear axle 54 be to slide onto the respectively rear end 342 of this arc groove 34 from the front end 341 of this arc groove 34 respectively, because respectively the rear end 342 of this arc groove 34 is than the perisporium near these axis holes 32, make that respectively the spacing between this roller 52 will be dwindled, as shown in Figure 6, can be in order to the bar of clamping than minor diameter.

By this, when the bar of different-diameter when waiting axle center of this locating wheel 30 and this driving wheel 40, need only adjust the respectively spacing between this roller 52, the feasible respectively spacing between this roller 52 and the diameter of this bar cooperatively interact, so that this bar firmly is held on respectively between this roller 52, make this bar comparatively stable and be difficult for rocking in process, reduce the vibrations that the bar rotation produced and the purpose of noise to reach.

In addition, this drive unit 60 is not limited to pneumatic cylinder, also can be devices such as oil hydraulic cylinder, motor, so long as can drive the device of this driving wheel 40, can reach the purpose of this utility model equally.
