Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Fig. 1 is one embodiment of the invention front schematic view;
Fig. 2 is horizontal transport embodiment illustrated in fig. 1 mechanism schematic top plan view;
Fig. 3 is thickness detection mechanism schematic diagram embodiment illustrated in fig. 1;
Fig. 4 is offset distance embodiment illustrated in fig. 1 testing agency schematic diagram.
Embodiment
As Fig. 1 one embodiment of the invention front schematic view; Fig. 2 is horizontal transport embodiment illustrated in fig. 1 mechanism schematic top plan view; In conjunction with this two figure, be explained:
This wheel hub feature detection device, has a frame 9, and a horizontal transport mechanism 10 has been fixed at its middle part; The travelling belt 11 and the part that is fixed on frame 9 that in this horizontal transport mechanism 10, have horizontal single-headed, wheel hub 90 lies against on travelling belt 11 in traveling process, and its rotating shaft keeps vertically.Travelling belt 11 is the flat passerby of two row, can dodge other devices of opening therebetween.
Begin in wheel hub 90 one end in horizontal transport mechanism 10, under the driving of travelling belt 11, level is advanced, according to the distance of setting, by travelling belt, march to middle position, the detent mechanism 20 that is fixed on horizontal transport mechanism 10 is located, 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 determined 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 symmetrical between two; And four swing arms 22 are controlled mutually to be gathered in surface level, 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; Therefore the side of wheel hub 90 can be gathered and clamp to four reference columns 23 when wheel hub 90 is positioned.In the both sides of horizontal transport mechanism 10, respectively there are two swing arms 22, the swing arm 22 of this homonymy separately end is matched with an arm shaft 24, to such an extent as to swing arm 22 can be in the fan-shaped swing of surface level; Meanwhile, 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, when wheel hub 90 advances to behind the position of detent mechanism 20, swing arm 22 is just carried out symmetrical fast clamp to its side simultaneously, determined the horizontal level of wheel hub 90 in horizontal transport mechanism 10, then swing arm 22 resets again, make wheel hub 90 naturally be statically placed in horizontal transport mechanism 10. visible, the detent mechanism 20 of these four swing arms can adapt to the wheel hub of different batches different-diameter on the one hand fast, adapts to the quick switching of streamline specification; Can after horizontal location, hightail on the other hand wheel hub, make follow-up---image-forming step is interference-free.
When wheel hub 90 is after static condition, be positioned at the offset distance testing agency 30 of frame 9 belows and the thickness detection mechanism 40 of top and measure non-interferencely offset distance and the thickness of wheel hub 90.As shown in Figure 3, this is the schematic 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 a upper measuring staff 42 and a lever 41 of fixing with it and the first microswitch 47 that touched by measuring staff 42; The 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, the first servo guide 45 drives the first slide 43 to drive upper measuring staff 42 to advance from top to bottom, until the lever 41 of upper measuring staff 42 ends returns after just touching wheel hub 90 wheel rims and triggering the first microswitch 47, the first servo guide 45 is determined wheel hub 90 thickness by measuring the displacement of the first slide 43.
As shown in Figure 4, the schematic diagram of Zhong Qi offset distance embodiment illustrated in fig. 1 testing agency 30; This offset distance testing agency 30 comprises one second fine motion leverage 35, is fixed on one second slide 34; Triggering the second microswitch 37 is arranged on the second slide 34; The 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 the second slide 34 to drive the second fine motion leverage 35 to advance from bottom to top, until touching of lower measuring staff 32 its ends 31 returned after just touching wheel hub 90 installed surfaces and triggering the second microswitch 37, the second servo guide 36 is determined the offset distance of wheel hub 90 by measuring the displacement of the second slide 34 simultaneously.Wherein touch 31 for disc, coaxially arrange with wheel hub 90.Visible, offset distance testing agency 30 and thickness detection mechanism 40 have all adopted fine motion leverage, touch wheel hub 90 test from upper and lower two reverse directions, and its step can be processed simultaneously and be non-interference, simple in structure, has saved the overall test time.Travelling belt 11 comprises synchronously advance in left and right two; Between the two, in horizontal transport mechanism 10, have a through hole, lower measuring staff 32 pumps through through hole.
When wheel hub 90 complete that offset distance detects and 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 sent with attitude by horizontal transport mechanism 10.Imaging mechanism 60 has the shooting of wheel hub 90 digital imageries 61, this takes 61 digital imagery that obtain will send to an analytical equipment, such as the analyser 70 of peripheral hardware is processed and monitored, the result of this digital imagery just can judge wheel hub external diameter, median pore diameter, PCD pitch diameter, spoke shape etc.; Take 61 its rotating shafts when wheel hub 90 is positioned with detent mechanism 20 and coaxially arrange, do not need wheel hub 90 carry out extra mobile can its end face imaging of Quick Acquisition.So far, all essential characteristics of wheel hub 90 detect complete; Analyser 70 can be external, also can be incorporated in frame 9.
Visible, wheel hub 90 is in testing process, and its attitude is constant, only after 20 horizontal location of detent mechanism, keeps standing, until finally output, step is succinctly reliable, and without additional displacement, 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, facilitate follow-up processing.
The above, only for preferred embodiment of the present invention, therefore can not limit according to this scope of the invention process, the equivalence of doing according to the scope of the claims of the present invention and description changes and modifies, and all should still belong in the scope that the present invention contains.
