Embodiment
Like Fig. 1 one embodiment of the invention front schematic view; Fig. 2 is a horizontal transport embodiment illustrated in fig. 1 mechanism schematic top plan view; Explain in conjunction with this two figure:
This wheel hub feature detection device has a frame 9, and a horizontal transport mechanism 10 has been fixed in the center; The travelling belt 11 and the part that is fixed in frame 9 of horizontal single-headed are arranged in this horizontal transport mechanism 10, and wheel hub 90 lies against in traveling process on the travelling belt 11, and its rotating shaft keeps vertically.Travelling belt 11 is the flat passerbys of two row, can dodge other devices of opening therebetween.
The end beginning of wheel hub 90 in horizontal transport mechanism 10; Level is advanced under the driving of travelling belt 11, and the distance according to setting marches to middle position by travelling belt; Be fixed on detent mechanism 20 location of horizontal transport mechanism 10; Detent mechanism 20 fixes with the part that frame 9 is fixed in horizontal transport mechanism 10, and its positioning element is positioned at travelling belt 11 tops, and this part has been confirmed the horizontal level of wheel hub 90 in horizontal transport mechanism 10.
The positioning element of detent mechanism 20 comprises four swing arms 22, and swing arm 22 is in surface level, and the both sides of the transmission direction of horizontal transport mechanism 10 are symmetry in twos; And four swing arms 22 are controlled to be gathered in surface level each other, is abutted against wheel hub 90 sides it is positioned; Swing arm 22 has a reference column 23 being abutted against in the top of wheel hub 90 sides; So wheel hub 90 when being positioned four reference columns 23 can gather and grasp the side of wheel hub 90.Respectively there are two swing arms 22 both sides in horizontal transport mechanism 10, the swing arm 22 of this homonymy separately tip engages in an arm shaft 24, to such an extent as to swing arm 22 can be in the fan-shaped swing of surface level; Simultaneously, the swing arm 22 of homonymy has meshed gears 25 each other, to such an extent as to can the rotation of locking phase subtend.So; Advance to the position of detent mechanism 20 when wheel hub 90 after, swing arm 22 has been confirmed the horizontal level of wheel hub 90 in horizontal transport mechanism 10 with regard to simultaneously its side being carried out the quick clamping of symmetry; Swing arm 22 resets again then; It is visible to make wheel hub 90 be statically placed in horizontal transport mechanism 10. naturally, and the wheel hub that the detent mechanism 20 of these four swing arms on the one hand can fast adaptation different batches different-diameter adapts to the quick switching of streamline specification; Can after horizontal location, hightail wheel hub on the other hand, make follow-up---image-forming step is interference-free.
After wheel hub 90 was in static condition, the offset distance and the thickness of wheel hub 90 was measured on the thickness detection mechanism 40 mutually noninterferes ground that is positioned at offset distance testing agency 30 and the top of frame 9 belows.As shown in Figure 3, this is the synoptic diagram of thickness detection mechanism 40; This thickness detection mechanism comprises one first fine motion leverage 46, is fixed on one first slide 43, comprises that one is gone up measuring staff 42 and a fixing with it lever 41 and first microswitch 47 that touched by measuring staff 42; First slide 43 slides up and down and is matched with a top guide bar 44 and the one first servo guide 45 parallel with top guide bar 44; After wheel hub 90 is statically placed in horizontal transport mechanism 10; 43 drives of first servo guide 45 drivings first slide are gone up measuring staff 42 and are advanced from top to bottom; After last measuring staff 42 terminal levers 41 just touch wheel hub 90 wheel rims and trigger first microswitch 47, return, the first servo guide 45 is confirmed wheel hub 90 thickness through the displacement of measuring first slide 43.
As shown in Figure 4, embodiment illustrated in fig. 1 in the synoptic diagram of its offset distance testing agency 30; This offset distance testing agency 30 comprises one second fine motion leverage 35, is fixed on one second slide 34; Triggering second microswitch 37 is installed on second slide 34; Second slide 34 slides up and down and is matched with lower guide rod 33, with the one second servo guide 36 parallel with lower guide rod 33; After wheel hub 90 is statically placed in horizontal transport mechanism 10; The second servo guide 36 drives second slide, 34 drives, the second fine motion leverage 35 and advances from bottom to top; It terminal touch 31 and promptly returns after just touching wheel hub 90 installed surfaces and triggering second microswitch 37 until following measuring staff 32, and the second servo guide 36 is confirmed the offset distance of wheel hub 90 through the displacement of measuring second slide 34 simultaneously.Wherein touch 31 and be disc, with wheel hub 90 coaxial settings.It is thus clear that offset distance testing agency 30 has all adopted the fine motion leverage with thickness detection mechanism 40, to touch wheel hub 90 from two reverse directions up and down and test, its step can be handled and mutually noninterfere simultaneously, and is simple in structure, practiced thrift the overall test time.Advance synchronously about travelling belt 11 comprises two; In horizontal transport mechanism 10, have a through hole between the two, following measuring staff 32 passes through hole and pumps.
When wheel hub 90 accomplish offset distances detect with the thickness detection after, the imaging mechanism 60 of frame 9 tops from wheel hub 90 end faces to its imaging processing; Last wheel hub 90 is seen off with attitude by horizontal transport mechanism 10.Imaging mechanism 60 has the shooting of wheel hub 90 digital imageries 61; This takes 61 digital imageries that obtain will send to an analytical equipment; Analyser 70 such as peripheral hardware is handled and is kept watch on, and the result of this digital imagery just can judge wheel hub external diameter, median pore diameter; The PCD pitch diameter, spoke shape etc.; Take the coaxial setting of 61 its rotating shafts when positioning, do not need wheel hub 90 to carry out extra moving and to gather its end face fast and form images with 20 pairs of wheel hubs 90 of detent mechanism.So far, all essential characteristics of wheel hub 90 detect and finish; Analyser 70 can be external, also can be incorporated on the frame 9.
It is thus clear that wheel hub 90 is in testing process, its attitude is constant, only leaves standstill through promptly keeping after 20 horizontal location of detent mechanism, and until last output, step is succinctly reliable, no additional displacement, and its detection speed is very fast, and the cycle is very short; Check consistency is good, and the noise of generation, vibration etc. are all very small.And this fast detecting can be used for Fast Classification, convenient follow-up processing.
The above is merely preferred embodiment of the present invention, so can not limit the scope that the present invention implements according to this, the equivalence of promptly doing according to claim of the present invention and description changes and modifies, and all should still belong in the scope that the present invention contains.
