The concrete structure of the first sensing unit is as follows:
Including symmetry and run through the first sensor 24 being installed in elastomer block 212, one end elasticity of extension block 212 of first sensor 24 also abuts against with the first connecting plate 213 being fixed in bottom first gauge head the 27, second gauge head 28.Each first sensor 24 is all locked by the first clamping block 26, is positioned at described first clamping block 26, is also set with the first chuck 211 in the periphery of first sensor 24.
Support 22 is also distinguished device the first limited post 214 and hydraulic bjuffer 215, first limited post 214 is for ensureing the connection location of elevating bracket 218 and support 22, the layout of hydraulic bjuffer 215 makes elevating bracket 218 ensure to put in place the most smoothly in downward displacement process, eliminate in its buffering, extension device service life.The two ends being positioned at support 22 are respectively and fixedly connected with the first proximity switch 25 and the second proximity switch 29, first proximity switch 25 and the second proximity switch 29 are arranged in relative dislocation, and the spacing between the first proximity switch 25 and the second proximity switch 29 is the displacement stroke of elevating bracket 218.
As shown in Fig. 6, Fig. 7 and Fig. 8, the concrete structure of lower measuring unit 3 is as follows: be made up of the second sensing unit and the second pneumatic gauging unit；
The concrete structure of described second pneumatic gauging unit is as follows:
Including the second cylinder 38 being installed in the first mounting seat 37, the outfan of the second cylinder 38 stretches out the first mounting seat 37 and is connected with the second floating junction 34, second floating junction 34 abuts against with the second limited post 314 being installed in guide plate 33, second guide pillar 35 is symmetrically arranged in the both sides of the second floating junction 34, its one end is installed in the first mounting seat 37 by the second linear bearing 36, the other end is connected with guide plate 33, is positioned at the periphery returning apparatus guide pin bushing 310 of the second guide pillar 35.Being positioned on guide plate 33 and also extend through device the second sensor 31, the periphery device second at the second sensor 31 clamps block 32, is positioned at the bottom of the second clamping block 32, in periphery returning apparatus second chuck 39 of the second sensor 31.
The concrete structure of the second sensing unit is as follows:
It is made up of the 3rd proximity switch the 311, the 4th proximity switch 317 and photoelectric sensor 315,3rd proximity switch 311 and the 4th proximity switch 317 are arranged in interval, and the interval between the 3rd proximity switch 311 and the 4th proximity switch 317 forms the displacement stroke of guide plate 33.3rd proximity switch 311 is affixed by the second connecting plate 312 with the first mounting seat 37；Described photoelectric sensor 315 is perpendicular and runs through and is installed in the second mounting seat 313, is positioned at the side of described second mounting seat 313, connects the 4th proximity switch 317 also by the 3rd connecting plate 316.
The specific works process of the present invention is as follows:
nullAs shown in Figure 5，When plunger 1 moves to the present invention，PLC controls the first cylinder 21 and works，The outfan of the first cylinder 21 stretches out and drives the first floating junction 210 to abut with elevating bracket 218，First floating junction 210 ensure that the outfan of the first cylinder 21 operates steadily，Thus drive elevating bracket 218 at the first enterprising line displacement of guide pillar 23，When moving to the second proximity switch 29，First cylinder 21 quits work，As shown in Figure 1，Now the first gauge head 27 and the second gauge head 28 contact along direction shown in F2 with the steel ball on plunger 1，Measure steel ball upper surface to spacing L2 of plunger 1 lower surface，Then measurement data is fed back to PLC carried out data acquisition by the first connecting plate 213 and first sensor 24，After collection, PLC controls the first cylinder 21 and works on，Until elevating bracket 218 moves to the first proximity switch 25，Again quit work，Measure with this iterative cycles.
nullAs shown in Figure 9，First pass through photoelectric sensor 315 and sense whether plunger 1 puts in place，If putting in place，Photoelectric sensor 315 works and transmits signal extremely external PLC，PLC sends instruction and controls the second cylinder 38 action，Its outfan moves upward and abuts against with the second limited post 314 in guide plate 33，Thus drive guide plate 33 at the second guide pillar 35 top offset，The displacement process of guide plate 33 is made to have higher stability by the second linear bearing 36 and guide pin bushing 310，Owing to the second sensor 31 device is on guide plate 33，Thus drive the second sensor 31 upwards，Until guide plate 33 move to the 4th proximity switch 317 in same level after，Now the 4th proximity switch 317 feedback information，PLC controls the second cylinder 38 and stops，As shown in Figure 1，Second sensor 31 contacts along F1 direction with the bottom tested surface of plunger 1，Then PLC secondary control the second cylinder 38 again starts，Until guide plate 33 moves to after being in same level with the 3rd proximity switch 311，3rd proximity switch 311 feedback information again，PLC controls the second cylinder 38 and stops，Above-mentioned steps carries out the measurement to plunger 1 lower end tested surface repeatedly.
Spacing L2 that twice is recorded by last PLC respectively carries out mathematic interpolation with L1, thus it is how many for showing that steel ball exposes the height L3 of plunger surface, judges this height L3 is sorted by subsequent sort mechanism after whether exceeding margin of tolerance value by PLC.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention sees claim, within protection scope of the present invention, can make any type of amendment.
