Rear sight fixed mount 5 connects firmly in the lower end of height adjusting slider 4, and rear sight fixed mount 5 is vertical with support bar 1, and the outside of rear sight fixed mount 5 is provided with digital display rule 7, and an end of rear sight fixed mount 5 is provided with digital display meter 15; Digital display meter 15 is fixed on the rear sight fixed mount 5 by hexagon socket cap head screw 14, and gauge outfit 13 is housed on the measuring head of digital display meter 15; The outside refers to the front end of rear sight fixed mount 5, end about an end of rear sight fixed mount 5 refers to; At digital display rule 7 benchmark guard rail 6 is housed; As shown in Figure 3, benchmark guard rail 6 is L shaped structure, its short transverse is the slide block structure with deixis, slide block structure and digital display rule 7 are flexibly connected, benchmark guard rail 6 can be slided along digital display rule 7, the positional value on the benchmark guard rail 6 current digital display rules 7 of living in can be read by the deixis district, be provided with the inclined-plane with gauge outfit 13 corresponding measuring positions on the benchmark guard rail 6, surface of contact when measuring to reduce, benchmark guard rail 6 is provided with screw 16, screw 16 can be used trip bolt, and screw 16 is used for benchmark guard rail 6 is fixed on digital display rule 7; Benchmark guard rail 6 has square groove and is flexibly connected with the backstay 8 that vertically arranges, backstay 8 passes the square groove of benchmark guard rail 6, can slide up and down along square groove, benchmark guard rail 6 is provided with trip bolt 12, be used for backstay 8 is fixed on benchmark guard rail 6, be connected with latch segment 9 in the lower end of backstay 8, latch segment 9 also is connected with auxiliary guard rail 10, latch segment 9 is provided with trip bolt 12, is used for assisting guard rail 10 to be fixed on latch segment 9; Latch segment 9 is arranged in the square groove of the left and right directions that has on the base 11.
Benchmark guard rail 6 is guard rails setting up outside the chi frame of digital display rule 7, the benchmark in the time of as digital display rule and digital display meter zero clearing.Height adjusting slider 4 is adjusting sliders of height gauge, its effect is to locate accurately the height that plastic bottle need to carry out the diameter measurement position, for example be located at the 80mm place, the diameter value measured of digital display meter and digital display rule is the diameter value at the 80mm place that makes progress at the bottom of the plastic bottle so.
Preferably, the calibration of digital display meter 15 is shown as 0.001mm; The calibration of digital display rule 7 is shown as 0.01mm.Digital display meter 15 is a kind of electronic digital centigrade indicators, utilizes the digital measurement display technique, and a kind of precision measurement utensil of reading is carried out in the straight-line displacement of sounding rod institute sensing, and measurement range is 0-10mm.Spring is the internal part of digital display centimeter, and effect is that the sounding rod that compression is entered dial gauge inside after measurement is finished is pulled out, and the initial tension of spring is 0.111N, and rigidity is 0.03N/mm.
When using the detection of plastic bottle diameter of the present invention and height-gauge, unclamp first screw 16, promote benchmark guard rail 6 and move to digital display meter 15 directions, stop when benchmark guard rail 6 touches the measuring head 13 of digital display meter 15, this moment, the reading with digital display rule and digital display meter was made as respectively zero; Then according to the diameter that indicates on the tested bottle drawing benchmark guard rail 6 is moved right, mobile distance be slightly less than the diameter of bottle (guarantee measuring accuracy, mobile distance less than bottle diameter 1~5mm all can); For example the diameter of bottle is 59mm, the 58mm that then the measuring basis limit can be moved right, and then with screw 16 lockings, the reading value (being the record value of digital display rule) of record digital display rule 7 this moment; Unclamp the trip bolt 12 on locking height adjusting slider 4 and the fine setting slide block 2, adjust the height and position of rear sight fixed mount 5, make the diameter measurement position of the nearly bottle of measurement edge joint of benchmark guard rail 6, trip bolt 12 on the locking fine setting slide block 2, then fine-tuning nut 3 comes the position of fine adjustment height adjusting slider 4, regulate the height of rear sight fixed mount 5 to the accurate height and position of the bottle diameter that needs to measure, then the trip bolt 12 on the locking height adjusting slider 4.
The plastic bottle of taking needs to detect at random after above-mentioned work is finished, the bottle end, contact fully with base 11, guarantee that it is in plumbness, plastic bottle institute location is put on the measuring basis limit that is attached to benchmark guard rail 6, and regulate auxiliary guard rail 10 to correct position, auxiliary bottle orientation, then latch segment 9 tightens screw 12.Promote tested bottle and move along the measuring basis limit of benchmark guard rail 6, when the gauge head of bottle measured diameter by digital display meter, digital display meter can be recorded end value automatically, and this moment, the record value record value that adds digital display rule of digital display meter was the diameter of this position of bottle.
The present invention can keep constant small dynamometry to remove to measure the outer dia of PET bottle, this power does not change because of user's difference, do not change because of the difference of service time yet, so the result that different personnel measure is the same, the result that the same personnel different time is measured also is constant.For traditional use kind of calliper, repeatability and the repdocutbility of measurement result are higher.The simplification of measuring (only needing plastic bottle is got final product along the side head of reference edge by digital display meter), single examine of diameter process required time was no more than for 1 second, and the single diameter required time of traditional kind of calliper is 3-5 second, with respect to the batch diameter measurement in the factory, can improve greatly detection speed and accuracy, stability.
