After at the first conveyer valve guide bushing being sent to the turning support of turning device, primary importance signal output apparatus sends a position signalling to signal master control set, it is anterior that primary importance signal output apparatus is arranged at the first connecting gear usually, to detect the disengaging of valve guide bushing and the first conveyer.After signal master control set receives position signalling, send and compress signal to hold down gag, compress drive unit and drive pressing plate, valve guide bushing compresses forward by the pressing plate that arrange corresponding to valve guide bushing, and meanwhile, the limited body restriction in front portion of valve guide bushing moves forward, so far, valve guide bushing is reversed bracket support, and meanwhile, limited body and pressing plate compress spacing respectively in the front and rear part of valve guide bushing.Be in static stable valve guide bushing and be now divided into two states, first, if when the endoporus of valve guide bushing front portion is on-right angle, namely front portion is now just on-right angle structure that probe is corresponding, here on-right angle structure can be chamfering or fillet etc., the probe of itself and correspondence position does not interfere extruding, then pop one's head in not because of the displacement that extruding occurs forward, elasticity trigger mechanism does not send triggering signal under the state of displacement of not popping one's head in; Second, if when the endoporus of valve guide bushing front portion is right angle, namely on-right angle structure is now positioned at the rear portion of valve guide rod, right-angle structure and probe then owing to being positioned at valve guide bushing front portion under this state interfere, probe is caused to be extruded forward, probe extrudes elasticity trigger mechanism thereupon, makes elasticity trigger mechanism send triggering signal.Here explanation is needed, for the measurement of above-mentioned the first and second two kinds of valve guide bushing direction states, if the press plate position that probe and a whole set of checkout gear are arranged at rear portion is measured, the fore-and-aft direction of valve guide bushing can be measured equally, only need be changed the locations of structures of checkout gear.After the testing of popping one's head in completes, separating mechanism makes valve guide bushing and probe separation, and the implication of separation is when valve guide bushing is displaced sideways, and it does not interfere with probe.Under two kinds of situations that signal master control set received or do not receive triggering signal, control overturning drive device respectively, turning support is overturn to the left or to the right, valve guide bushing is tumbled under gravity to forward connecting gear or commutation connecting gear.When valve guide bushing tumbles to forward connecting gear, forward connecting gear transmits valve guide bushing forward to main connecting gear; When valve guide bushing tumbles to commutation connecting gear, commutation connecting gear transmits rearward logical for valve guide bushing, and by semicircular transport track, valve guide bushing is sent to the rear portion of forward connecting gear, realize the commutation of valve guide bushing, or commutation connecting gear rotates 180 degree from horizontal plane, after realizing the commutation of valve guide bushing, then forwarded to main connecting gear.
In prior art, in order to realize the walking direction to valve guide bushing, when production and processing valve guide bushing, groove need be processed in a certain position of valve guide bushing outer surface, so by the radial direction in transfer equipment pop one's head according to the detection of groove is differentiated valve guide bushing direction of transfer just or instead.Although this technological design completes the work transmitting and differentiate direction, but result in outside the functional structure of valve guide bushing removing needed for engine operation simultaneously, multi-processing outer surface groove, and be just slickness and the integrality that this groove have impact on valve guide bushing outer surface, the axiality of valve oil seal and conduit is caused to reduce, make valve oil seal that just rate is installed not to increase, also reduce the width of valve oil seal band simultaneously, affect sealing property.And then affect the combination property of engine.Thus, compared to technological design of the prior art, valve guide bushing transfer equipment provided by the invention, while the accuracy not affecting transmission work and differentiation direction, avoids the existence of the redundancy structure of valve guide bushing, thus eliminates the interference of equipment to overall engine performance.
Transmit about valve guide bushing in the preferred embodiment of method for sorting a kind of, the valve guide bushing sent is positioned and compresses to determine that it detects position.Meanwhile, probe in the end Internal periphery of compacted valve guide bushing and checkout gear offsets, when the end Internal periphery at the place of offseting is on-right angle, there is not location conflicts in end Internal periphery therewith of popping one's head in, then pop one's head in and be not pushed and then cause the triggering of signal, it is forward that this state is judged as valve guide bushing, is now overturn to the first avris by valve guide bushing, valve guide bushing is tumbled to forward connecting gear, and then forwards; When the end Internal periphery at the place of offseting is right angle, to pop one's head in end Internal periphery generation location conflicts therewith, then probe is pushed and then causes the triggering of signal, and it is reverse that this state is judged as valve guide bushing, is now overturn to Second Edge side by valve guide bushing, valve guide bushing is made to tumble to commutation connecting gear, commutation connecting gear comprises two kinds of load modes, the first, and commutation connecting gear rotates 180 degree from horizontal plane, then make valve guide bushing commutate, and then forward; Second, commutation connecting gear transmits rearward logical for valve guide bushing, and by semicircular transport track, valve guide bushing is sent to the rear portion of forward connecting gear, realize the commutation of valve guide bushing, this transport process just makes valve guide bushing achieve the commutation of 180 degree, and then is forwarded by valve guide bushing again.
In the method, crucial step is that probe detects the on-right angle of valve guide bushing end Internal periphery or right-angle structure, and then carries out forwarding forward or after turning to again.The right angle of the valve guide bushing that the method detects or on-right angle structure are that valve guide bushing is processed for meeting engine using function demand.In contrast prior art in order to discriminating direction herein separately on the impact on overall engine performance that valve guide bushing processing redundancy groove causes, this method avoids the destruction to valve guide bushing surface smoothness and integrality, thus eliminate the interference to overall engine performance.

Core of the present invention is to provide a kind of valve guide bushing transfer equipment and valve guide bushing transmits method for sorting.Transmitting method for sorting by using this valve guide bushing transfer equipment and valve guide bushing to transmit valve guide bushing and sort, avoiding the structure existence of valve guide bushing except duty of engine demand except, the comprehensive serviceability of engine is significantly improved.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 2 to Fig. 5, contrast Fig. 2 to Fig. 5 discusses by following detailed description of the invention.
According to figure, in the present invention, emphasis is the setting to checkout gear 4, i.e. the detection of checkout gear 4 pairs of valve guide bushing end Internal periphery.Specifically, the Internal periphery at the valve guide bushing two ends that this equipment is corresponding is respectively on-right angle structure and right-angle structure, and common on-right angle structure is chamfering.Probe 41 in checkout gear 4 is corresponding with the on-right angle structure of end Internal periphery to be arranged, when on-right angle structure offsets with probe 41, the locally embedding of probe 41 is to the position, space of the processed cutting of on-right angle structure, such as chamfering, chamfering position by pop one's head in 41 local nested condition under, probe 41 and the on-right angle structure of end Internal periphery do not interfere.On the contrary, when right-angle structure offsets with probe 41, the local of probe 41 interferes with the end not being cut processing, then probe 41 is extruded and moves.Elasticity trigger mechanism in checkout gear 4 42 is assemblied in one with probe 41, and under the two states that probe 41 to be extruded by valve guide bushing by foregoing description or do not extrude, elasticity trigger mechanism 42 can output signal according to setting.When valve guide bushing is detected, it is reversed turning support 21 support in device 2, and the pressing plate 31 in the compacted device 3 in its rear portion compresses forward, and anterior limited body restriction anterior displacement, so, detected valve guide bushing is in stable state.
Be the first conveyer 1 at switching mechanism 21 rear portion, first conveyer 1 comprises the first drive unit, the first connecting gear 12 and primary importance signal output apparatus 11, wherein, first connecting gear 12 is made up of feed belt usually, first drive unit drives feed belt circulating rolling to transmit valve guide bushing, when the afterbody of valve guide bushing from the first conveyer 1 departs from, after entering turning device 2, primary importance signal output apparatus 11, when detecting that valve guide bushing transmits output, sends signal.
Turning support 21 in turning device 2 is connected with overturning drive device, have on the basis of support valve guide bushing function at turning support 21, overturning drive device can drive turning support 21 with valve guide bushing direction of transfer forward for axially carrying out rotation to the left or to the right, and this turn over function is intended to the valve guide bushing after making detection and tumbles to the left or to the right to the second follow-up conveyer 5.
The hold down gag 3 being positioned at turning device 2 rear portion comprises pressing plate 31 and compresses drive unit, compresses drive unit and is connected with pressing plate 31, and compress drive unit and can controllably drive pressing plate 31 to exert pressure forward, object is compressed forward by valve guide bushing.In order to ensure valve guide bushing in the positional accuracy being embedded detection by probe 41, the limit body of valve guide bushing front portion is arranged on the avris of probe 41, and common setting is that limit body is set to block, is fixed on by block on checkout gear 4.After limit body determines position, valve guide bushing is compressed by the pressing plate 31 of afterbody, spacing by the limit body of front portion.
Be detected device 4 at valve guide bushing to detect forward or backwards, before turning device 2 overturns to the left or to the right, need the end of valve guide bushing to be separated with probe 41, when the standard of separation is with valve guide bushing generation side rolling, it does not interfere collision with probe 41.This state be separated needs checkout gear 4 and turning support 21 relative separation to move or valve guide bushing and checkout gear 4 relative separation move, and the effect of separating mechanism is just this.
Signal master control set in the present invention can be connected communicatedly with each apparatus system respectively, and it, by Received signal strength, carries out control operation.Such as, after receiving the position signalling that primary importance signal output apparatus 11 sends, just determine valve guide bushing and be transferred out the first connecting gear 1, enter turning device 2, and then signal master control set sends signal and makes the action of compression drive unit, compressed forward by pressing plate 31 pairs of valve guide bushings.
Second conveyer 5 is located at " rear portion " of turning device 2 in logic function, is similar to the first conveyer 1 and is positioned at turning device 2 front portion, and valve guide bushing is flowed to turning device 2.And in practical structures, the second conveyer 5 comprises forward connecting gear 51, commutation connecting gear 52 and main connecting gear.The function of corresponding turning device 2 and structure, forward connecting gear 51 is arranged at the first avris of turning device 2, when the testing result of checkout gear 4 pairs of valve guide bushings is " just ", turning device 2 overturns to the first avris, make valve guide bushing drop down onto forward connecting gear 51, and then valve guide bushing forward to main connecting gear by forward connecting gear 51; On the contrary, when the testing result of checkout gear 4 pairs of valve guide bushings is negations, turning device 2 overturns to Second Edge side, commutation connecting gear 52 is positioned at the Second Edge side position of turning device 2, fall within the valve guide bushing of commutation connecting gear 52 after commutation, forward, different according to the work structuring principle of commutation connecting gear 52 here, it is connected with main connecting gear or forward connecting gear 51 again.Here linking, can be understood as the independent operating that the head and the tail of two cover conveyer belts or cylinder conveyer are close, and when valve guide bushing spreads out of from a certain conveyer belt, it is just received by next conveyer belt and continues conveying.The implication be connected also is applicable to the position relationship between the first connecting gear 12 and turning support 21.
