Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
See accompanying drawing 1,2,3,4,5,6, a kind of ball cage retainer automatic checkout system,
Comprise frame 23, sucker 2, amount head bracket 3, camera 4, camera bracket 5, slide 6, slide rail 7, slide cylinder 8, measurer and main control computer.
Affixed described slide rail 7 in described frame 23, described slide 6 is sleeved on described slide rail 7, and its one end is connected with the cylinder rod of the slide cylinder 8 be fixed in described frame 23, slides under slide cylinder 8 acts on along slide rail 7; Described amount head bracket 3 is fixed on frame 23 on the end face of described slide 6 side, and amount head bracket 3 fixes two measurers; Described slide 6 is provided with described camera bracket 5 near cylinder side, and described camera bracket 5 connects described camera 4, and described camera 4 optical axis direction is parallel with described slide rail 7 direction; Described slide 6 is provided with motor away from described cylinder side, and described sucker 2, perpendicular to described slide rail 7 direction, described machine shaft is fixed in described machine shaft direction.
Described two measurers are completely the same, comprise fixed mount 18, claw, encoding strip 17 and cylinder; Described fixed mount 18 one end is arranged on described amount head bracket 3; Parallel above described fixed mount 18 claw slide rail, encoding strip 17 and the first cylinder 9 are installed; First claw 10, second claw 11 and the 3rd claw 12 are sleeved on described claw slide rail along deviating from described first cylinder 9 direction order, its end measuring surface is each fixes a measuring head 13, the other end is respectively provided with read head, and described read head is positioned at directly over described encoding strip 17; Between first claw 10 and the second claw 11, between the 3rd claw 12 and fixed mount 18, be respectively provided with a linking springs along slide rail direction, and the 3rd claw 12 is fixedly connected with the cylinder axis of the first cylinder 9;
Installing plate 21 is fixed with below described fixed mount 18, the second cylinder 20 is fixed below described installing plate 21, described installing plate 21 has chute towards described fixed mount 18 one side, and be provided with draw back plate 19 in described chute, draw back plate 19 one end connects the cylinder rod of the second cylinder 20 by support; First claw 10 and the second claw 11 back are provided with guide rod, and described guide rod passes described fixed mount 18, described guide rod end bearing set 22, free movement in two through holes that described bearing 22 can be arranged with on described draw back plate 19.
With 1 circumference uniform distribution six hole on retainer, need detect the working width of each punching, punching is that the example course of work of the present utility model and principle are as follows to processing end face distance and punching spacing: (1) retainer 1 is adsorbed by sucker 2, slide cylinder 8 promotes slide 6 makes retainer 1 move to measuring position, driven by motor sucker 2 makes retainer 1 rotate simultaneously, until camera 4 take the photograph in picture and occur location feature, now retainer two adjacent holes is by two measuring claws of aligning two measurers.
The one side in and hole wide to hole corresponding on retainer and retainer end distance are from carrying out an accuracy detection respectively for (2) two measurers, and the range accuracy simultaneously between camera 4 pairs of retainer two adjacent holes detects;
(3) slide cylinder 8 promotes slide 6 and makes retainer 1 leave measuring claw, and retainer 1 rotates 60 degree, and the spacing of two adjacent holes of camera 4 pairs of retainers 1 carries out accuracy detection;
(4) retainer 1 rotates 60 degree, and slide cylinder 8 promotes slide 6 makes retainer 1 move to measuring position.
Repeat (2) to (3) process twice above, like this phase closing precision in six holes of retainer is all detected.
Suppose from retainer is lived firmly by sucker suction, the time moving to measuring position to retainer is t, and during gage measuring, compole is short ignores, and the time that retainer rotates once is also t, so according to testing process above, the time detecting a retainer is 12t.
Due on retainer 1 six holes be uniformly distributed, when two measurers be 60 degree or 120 degree time, two measurers can keep motionless, and the first claw 10 on measurer and the measuring head 13 on the second claw 11 can enter in two adjacent holes on retainer 1 smoothly.
When the first claw 10 contacts with hole wall with the measuring head 13 on the second claw 11, when 3rd claw 12 contacts with the reference field on sucker 2, three springs are compressed, three contact points distance is between any two the measurement data of the retainer 1 that will survey, and range data is between any two read by the data-signal on encoding strip 17.In addition, measurer is provided with the first cylinder 9 and the second cylinder 20; First cylinder 9 is the strokes needed to, thus makes the spring between measurer claw and cylinder have a stable decrement, so just can ensure the contact force between measurer claw and workpiece, also ensure that the precision of measurement; Second cylinder 20 is that such the utility model can the different model when not changing claw for retainer detect in order to make the 3rd claw 12 on measurer draw in.
Here camera 4 also has two effects: one is coordinate sucker 2 gearing to position retainer, makes retainer two adjacent holes aim at the measuring claw of two measurers; That accuracy detection is carried out to the spacing of two adjacent holes of retainer 1 in addition.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
