Frame 1 has base plate and the both sides side plate vertical with base plate, and base plate and side plate are for the fixed cell of fixing each cylinder and grating scale.
The course of work of the present utility model and principle are as follows:
Retainer 100 is entered by charging track 2, and near the end of charging track 2, retainer 100 is positioned, and is detected by testing agency; Subsequently, enter blanking track, in the process of blanking orbit transports, certified products and substandard products are carried out to go-no-go, certified products are from the output of blanking track, and substandard products are sorted away in the switching process of cutting plate.Concrete process is as follows:
As shown in Figure 1, the surfaces externally and internally forming after turning is the retainer that sphere, two ends are plane.Therefore, in the time that retainer 100 is placed on the downward-sloping material loading base plate 2a of charging track 2, can on material loading base plate 2a, roll because of deadweight, a transverse plane of retainer 100 sticks a side plate 2b of material track, while being rolled to the detection position of setting, being blocked it by the first baffle plate 31 continues to roll, second baffle cylinder 72 moves, second baffle 32 is rotated down to be opened, against and compress the opposite side of retainer 100 outside surfaces, the first baffle plate 31 one in front and one in back compresses retainer with second baffle 32, and material loading base plate 2a has also played the positioning action while measurement.An end face of retainer 100 touch a side plate 2b of material loading track, and another end face of retainer 100 is also plane.When measurement, highly measuring cylinder 74 moves, the measurement plate 74b that promotion is fixed on the first slide block 74a moves, measuring plate 74b is two parallel plates, vertical with retainer 100 end faces, also simultaneously in succession on the first slide block 74a grating scale of the first grating scale, highly measuring under the promotion of cylinder 74, measure the end face that plate 74b firmly pushes down retainer 100, other each end face of retainer 100 pastes a firm material loading track side plate 2b in the inner part, as shown in Figure 3, this model machine has been measured the height of retainer.Material loading track this side plate 2b is in the inner part provided with square opening, so that measuring sonde 5 activities in retainer wall thickness measuring process subsequently.
Subsequently, automatic detection device is measured the wall thickness of retainer 100, detailed process and principle are as follows: the outside surface of retainer 100 is blocked and fixes by each baffle plate (the first baffle plate 31, second baffle 32, measurement plate 74b and plane of orientation), has just known wall thickness as long as measure the inside surface of retainer 100.Therefore, designed a measuring sonde 5 inside surface of retainer is measured, measuring sonde 5 can stretch under the effect of cylinder 76 at probe, does axially and radial motion with respect to retainer 100, can stretch into and exit and hold frame inside, and can in retainer, radially move.In measuring process, first, thickness measure cylinder 75 moves, the second slide block 75a slides (near retainer direction), drives measuring sonde 5 and probe to stretch into cylinder 76 and is moved to together near retainer central axis position, and positioning cylinder 73 moves, centralized positioning plate 33 is declined, thickness measure cylinder 75 resets, and the second slide block 75a slides (away from retainer direction), is blocked and be positioned at the central axis position of retainer by centralized positioning plate 33; Now, probe stretches into cylinder 76 and moves, drive measuring sonde 5 to stretch into retainer 100 centers, thickness measure cylinder 75 moves, the second slide block 75a slides (near retainer direction), drive measuring sonde 5 and probe to stretch into cylinder 76 and do radial motion in the inside of retainer 100 with respect to retainer together, in the time that probe 5a touches retainer 100 inside surface, stop.Because the grating scale of the second grating scale 42 is connected in this second slide block 75a above, so just measure the thickness of retainer 100.
Subsequently, each cylinder resets successively, and the first baffle plate cylinder 71 moves, and the first baffle plate 31 is retracted, and retainer 100 rolls forward, enters blanking track 6.The first baffle plate cylinder 71 resets, and the first baffle plate 31 stretches out, ready for entering next detection operation.Blanking track 6 has downward-sloping blanking base plate 6a, on blanking base plate 6a, is provided with cutting plate 6c, and this cutting plate 6c forms a part of blanking base plate 6a; When after detecting, the result of data analysis is substandard product, cutting plate 6c retracts under the effect of sub-material cylinder 77, and retainer 100 is rolled to substandard product and collects in frame; When after detecting, the result of data analysis is specification product, retainer 100 is rolled to specification product along blanking track 6 and collects in frame; Thereby realize the whole process that go-on-go certified products automatically detected.
The reference data of the utility model optical grating ruler measurement measures by the standard to retainer, and benchmark is provided and stored in storer, when measurement, by the data that record and reference data are compared, draw the qualified and underproof judged result of detected workpiece.This is prior art, does not describe in detail at this.Accurate for guarantee to detect numerical value at every turn, what the utility model adopted is relative reading, adopts numerical value that is: at every turn, be read zero point relative coordinate with the difference of workpiece relative coordinate, can avoid so the cheap deviation of grating scale, improve the degree of accuracy of detection.
Certainly, the utility model also has other embodiments, and listed is above only preferred embodiment of the present utility model, is not used for limiting practical range of the present utility model, all equivalences of doing according to the content of the application's the scope of the claims change and modify, and all should be technology category of the present utility model.
