Particularly: as shown in Figure 2, described guiding mechanism 1 comprises the first jib 11 that is hollow structure, the second jib 12 and the 3rd jib 13, described the first jib 11 and the second jib 12 inwalls are provided with interior slide rail 14 and fixed pulley 16, described the second jib 12 and the 3rd jib 13 outer walls are provided with pulley 15 and external slide rail 17, described the second jib 12 is set in described the first jib 11 inside, by the interior slide rail 14 on described the first jib 11 and the pulley 15 on described the second jib 12, fixed pulley 16 on described the first jib 11 coordinates with external slide rail 17 on described the second jib 12, realize stretching out and retraction of the second jib 12, described the 3rd jib 13 is set in the inside of described the second jib 12, by the interior slide rail 14 on described the second jib 12 and the pulley 15 on described the 3rd jib 13, fixed pulley 16 on described the second jib 11 coordinates with external slide rail 17 on described the 3rd jib 12, realize stretching out and retraction of the 3rd jib 13
.
The head end 31 of described flexible rack 3 is fixedly connected with described the 3rd jib 13, when flexible rack 3 stretches out, head end 31 drives the 3rd jib 13 to stretch out, after the 3rd jib 13 stretches out completely, drive the second jib 12 to stretch out, guaranteed that flexible rack 3 realizes rectilinear motion accurately, and the length of described the first jib 11, the second jibs 12 and the 3rd jib 13 can be sent to distance according to workpiece and sets.
As shown in Fig. 3 a and 3b, described head end 31 comprises pitch plate 311, bearing pin 312, axle sleeve 313, two-row roller 314 and extension spring 315, described axle sleeve 313 is fixed in described two-row roller 314, described two-row roller 314 is coordinated and is movably fixed between former and later two pitch plates 311 by bearing pin 312 and axle sleeve 313, described pitch plate 311 has front end and rear end, described front end is provided with tenon 316, described rear end is provided with the mortise 317 closing with described tenon 316 phase joggles, between two adjacent pitch plates 311, adopt the mode that joggle closes to connect, described extension spring 315 be fastened on adjacent two-row roller 314 between axle sleeve 313 on, by adjacent two pitch plate 311 tensions, to guarantee that tenon 316 has good contacting with mortise 317, and head end 311 is linearly, front end 318 and the bearing pin 312 of described pitch plate 311, rear end 319 and the axle sleeve 313 of pitch plate 311 are interference fit, described bearing pin 312 and axle sleeve 313, two-row roller 314 is matched in clearance with axle sleeve 313.
As shown in Figure 4, described engaging piece 32 is connected with head end 31, it comprises roller 321, axle sleeve 313, interior pitch plate 323, outer pitch plate 324 and bearing pin 312, described roller 321 is contained on described axle sleeve 313, between adjacent two rollers 321, by interior pitch plate 323, be connected to form engagement group, between adjacent two engagement groups, by outer pitch plate 324 and bearing pin 312, be connected to form hinge type engaging piece, described outer pitch plate 324, interior pitch plate 323 and axle sleeve 313 connect by described bearing pin 312, between described interior pitch plate 323 and axle sleeve 313, between described outer pitch plate 324 and bearing pin 312, be interference fit, between described roller 321 and axle sleeve 313, between described axle sleeve 313 and bearing pin 312, be matched in clearance.
The gear teeth of described wildhaber-novikov gear 2 are " circular arc-circular arc " shape flank profil, and when described wildhaber-novikov gear 2 meshes with described tooth bar engaging piece 32, described roller 321 is engaged in the gear teeth, and described wildhaber-novikov gear 2 rotates under the driving of motor.
If tooth bar is longer, described rack case 4 is interior arranges circular-arc rail groove, when flexible rack 3 is regained, can roll up and be placed in circular-arc rail groove, described rack case 4 has circular arc outer baffle 41, described circular arc outer baffle 41 forms the raceway of tooth bar together with guiding mechanism, for the roller on tooth bar, make rolling movement, to reduce the resistance of motion.
The quick delivery device of disclosed flexible manufacturing production line, its operation principle is: when needs push workpiece, actuating motor drives wildhaber-novikov gear 2 forwards, now thereby gear teeth pushing rolling wheels 321 drives engaging piece 32 reaches, described head end 31 stretches out under the promotion of described engaging piece 32, by being located at the workpiece placing device in the place ahead, workpiece to be processed is delivered to assigned address, after completing, motor drives wildhaber-novikov gear 2 reversions, thereby flexible rack 3 is regained.
Smooth in the interior operation of rack case 4 in order to guarantee flexible rack 3, except having good lubricating condition, also to guarantee that roller 321 radiuses are slightly less than gear teeth arc radius, the radius of circular arc outer baffle 41 be greater than wildhaber-novikov gear 2 and roller 321 radius and, otherwise wildhaber-novikov gear 2, can block between flexible rack 3 and circular arc outer baffle 41.
As shown in Figure 5, in reality engagement, roller on flexible rack is subject to the outside thrust of wildhaber-novikov gear, again because the speed of service of flexible rack is higher, so the centrifugal force producing is also larger, two power all force roller to be attached on circular arc outer baffle and move, due to wildhaber-novikov gear, gap affects between roller and circular arc outer baffle three, the distance that forces the movement locus at roller center to move a s outward, cause the transmission of this wildhaber-novikov gear and flexible rack to depart to a certain extent ideal movements track, now, the radius of roller center actual motion track is
, the theory movement track of roller should overlap with the reference circle of gear, therefore theory movement orbital radius is wildhaber-novikov gear reference radius
r, so
yet by the gear teeth radius to wildhaber-novikov gear, the adjusting setting of roller radius and circular arc outer baffle radius, can dwindle the outset of movement locus from s, thereby realize this accurate propelling movement fast.
Technology contents and the technical characterictic of invention have disclosed as above; yet those of ordinary skill in the art still may be based on teaching of the present invention and announcements and are done all replacement and modifications that does not deviate from spirit of the present invention; therefore; protection domain of the present invention should be not limited to the content that embodiment discloses; and should comprise various do not deviate from replacement of the present invention and modifications, and contained by present patent application claim.
