The specific embodiment
As shown in the figure: 1 is cylinder block, be built-in with cylinder piston 2 in cylinder block 1, sealing ring 3 and sealing ring 4 are arranged on cylinder piston 2, drive end bearing bracket 5 and rear end cap 6 on cylinder block of being fixed by bolts to 1 are arranged in the both sides of cylinder piston 2, be separately installed with the sealing ring 7 and the outside sealing ring 8 that are positioned at cylinder block 1 inside on the drive end bearing bracket 5, the sealing ring 9 that is positioned at cylinder block 1 is installed on the rear end cap 6.
In letter sorting cylinder block 1 upper grooves movable block 17 and movable block 18 are housed, movable block 17 and movable block 18 both sides have holddown spring 19 and holddown spring 20 respectively, by flat head screw attachment screw clamper 21, pass through flat head screw attachment screw clamper 22 on the movable block 18 on the movable block 17.
Be processed with air flue 35 in the cylinder block 1, and be provided with gas circuit blocking bar 24 and ejector spring 25, bolt fixing on gas circuit blocking bar 24 outer ends and the piston connecting plate 10 leans mutually, and the inner leans mutually with ejector spring 25.Be equipped with at cylinder block 1 downside and send nail pipe joint 26, send nail pipe joint 26 to be pressed on the cylinder block 1, send nail to be connected to curved shape below the pipe joint 26 and send nail pipe 27 by stator.
Have at cylinder block 1 top by screw and the fixing top board 28 of alignment pin, top board 28 is pushed down screw clamper 21 and screw clamper 22 and is made it can only the along continuous straight runs motion.At cylinder block 1 rear side, the backboard 29 that is connected with cylinder block 1 by bolt is arranged, between cylinder block 1 and backboard 29, there are two cushion covers to make backboard 29 and screw gaffing device 15 and screw gaffing device 16 maintain certain clearance, so that its reciprocating motion.The baffle plate rear side is equipped with screw material road 30 and the screw material road 31 of carrying the screw that the permutation device puts in order out.
During operation, cylinder block 1 and road 35 all join with air control unit.Cylinder piston 2 changes under the effect of direction at air pressure, does in cylinder block 1 and stretches out the back and forth movement that----returned, and each coming and going is a working cycles.When cylinder piston 2 does not stretch out, isolated screw when the lowest part that send nail pipe 27 has on one once working cycles, steel ball 23 divides inconsistent with the large diameter part of cylinder piston 2, under the effect of steel ball 23, movable block 17 and movable block 18 are to both sides compressing holddown spring 19 and holddown spring 20, make its contraction, screw clamper 21 and screw clamper 22 are in open state, on screw material road 30 and screw material road 31, be arranged in order 33 places, last plane through the screw after the permutation to screw gaffing device 15.When stretching out left under the effect of cylinder piston 2 at air pressure, driving piston connecting plate 10 is synchronized with the movement forward, piston connecting plate 10 drives connecting plate 12 by connecting pin 11, and connecting plate 12 is by fixed head 13 and fixed head 14 drives screw gaffing device 15 and screw gaffing device 16 is done synchronous rectilinear motion.The wedge surface of screw gaffing device 16 separates with the screw that is close to top screw in the process of advancing at the screw rod place, screw after the separation advances to the locating slot place of top board 28 along with screw gaffing device 15 and screw gaffing device 16 moves under the squeezing action of the passage 32 that the skewed slot of being made up of two wedge surfaces promptly tilts.In the process of advancing of cylinder piston 2, the cylinder piston 2 that supports steel ball 23 is moved to supporting at place, thin footpath by the particle size place, steel ball 23 moves down, the movable block 17 that steel ball 23 supports and movable block 18 drives screw clamper 21 under the pressure effect of holddown spring 19 and holddown spring 20 and screw clamper 22 is close pushes the screw clamping of coming with screw gaffing device 15 and screw gaffing device 16 and holds.The shank of bolt of gas circuit blocking bar 24 fronts stretches out when cylinder piston 2 stretches out synchronously, under the effect of ejector spring 25, gas circuit blocking bar 24 stretches out in pore, make the hole of air flue 35 through placing ejector spring 25, send the endoporus of nail pipe joint 26 to communicate with the gas circuit of sending nail pipe 27, blow screw to the screw that send nail pipe 27 lowest parts and export the connector place and carry out fastening.After cylinder piston 2 stretches out and puts in place,, make cylinder piston 2 and related part thereof back do reseting movement at the effect therapeutic method to keep the adverse qi flowing downward deferent change airintake direction of control device.During reseting movement, under the contention effect of bolt, compression ejector spring 25 resets gas circuit blocking bar 24 in front, and the gas circuit of nail pipe 27 is sent in blocking in moving process.Along with the return motion of cylinder piston 2, the piston rod that supports steel ball 23 becomes the particle size part by the small diameter part branch, and steel ball moves on 23 positions, drives movable block 17 and movable block 18 compressing holddown springs 19 and holddown spring 20 and shrinks.Screw clamper 21 and screw clamper 22 are opened under the drive of movable block 17 and movable block 18, unclamp the screw of clamping.Screw passes cylinder block 1 inside under the gravity effect hole along the endoporus that send nail pipe joint 26, send 27 landings of nail pipe to the lowest part that send nail pipe 27.Do the screw gaffing device 15 and the screw gaffing device 16 that are synchronized with the movement with cylinder piston 2 and also return original position, after screw gaffing device 16 is return original position, screw moves to the plane of screw gaffing device 15 under external force in screw material road 30 and screw material road 31 before, prepare to separate once more.So far a working cycles is finished.Along with the reciprocating motion of cylinder piston 2, screw is in this way by continuous separation and supply.
The utility model has adopted the reciprocating motion of a cylinder main body to finish the letter sorting and the supply of screw.Finish the letter sorting of screw and add when cylinder stretches out and hold, the threeway that cylinder piston stretches out cylinder block when putting in place connects, to last time isolated screw blow and put in place, when cylinder shrank, threeway was closed, and stops the air blowing to screw, clamper is opened, and the screw landing of separation is to the lowest part that send the nail pipe.
