Abstract
The utility model discloses a measuring rule, which is composed of a rule body, an indication seat, a reset key, a conversion key, a sensor, a display screen, a sighting telescope and devices connected mutually. Indications are arranged on the indication seat; zero can be set from any position by the reset key, and the conversion key can change calculation units when the length is measured; a bottom rule and a connecting plate form a fixed connecting rule body with a guide plate provided with a fixed sheet; a slide plate seat can slide on the connecting ruler body. The utility model adopts structure of simultaneous indication alignment and digital display, overcomes the human error of the estimated reading and the insufficiency of the rule body slope reading, sets the zero from any position, eliminates the system error and improves the measuring precision.
Description
The utility model relates to a kind of measurement patterned surface measurement of length chi.
Present figure mapping operation is used romer or linear scale to carry out length surface by operating personnel and is measured.The minimum delineation of romer is spaced apart 1mm, and the minimum delineation of linear scale is spaced apart 1mm and 0.2mm.Owing to use romer or linear scale when carrying out length interval reading numerical values, all need to estimate reading, and artificial decision-making ability be different, so can not guarantee the accuracy of length interval measurement well.Also because all on inclination chi face, there is bigger angle in the delineation line of romer or linear scale with the plane graphing, when aiming at optical system, the artificial collimation error also influences measuring accuracy easily.
The purpose of this utility model provides a kind of dip stick, can show the patterned surface length of required measurement automatically.
For achieving the above object, the technical scheme that the utility model is taked is: on the chi body of common survey chi, increase sensor, display screen, have the index seat of index and slidably the device.The screw rod that is connected and fixed on the plate by the slide plate bracing or strutting arrangement places jog wheels and fine motion plate endoporus, and the sensor of settling on the slide plate chair after the enforcement braked wheel is fastening can be shown in the numeral of the enterprising line length measured value of display screen by the spacing stator on guide plate of slide plate sheet.The index seat that index is housed is connected on the slide plate chair and with it and moves, and index is positioned at chi inclined-plane, end linear edge.The dwang of microscope base is equipped with rotor plate and is inserted in the lens barrel that has gun sight and can turns to the index center.Take-off the brake wheel back can be carried out 1 meter back and forth movement in the length range by the slide plate bracing or strutting arrangement on the guide plate that connects end chi and connecting plate.Reset key on the housing can initial at an arbitrary position zero setting, and the arithmetic unit when shift key can change linear measure longimetry is measured numerical value and all shown on display screen.
Owing to adopt the structure of index aligning and digital display synchronization during survey measurements, thereby eliminated the caused error of artificial estimation reading; Use optical laying directly to aim at index and target, overcome the deficiency of chi body inclined-plane reading; Reset key can initial at an arbitrary position zero setting, has eliminated systematic error, has improved measuring accuracy.Index is positioned at the upper end on drawing plane, has avoided scratching the surface of drawing or diaphragm base.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is an one-piece construction synoptic diagram of the present utility model;
Fig. 2 is a side view of the present utility model.
In one-piece construction figure shown in Figure 1: index 7 is connected to each other the formation alignment portion with index seat 6; Slide plate chair 9 is mounted with fixed head 5 and connects jog wheels 3 and fine motion plate 2 by screw rod 4, and fixedly braked wheel 1 can carry out measurement of micromovements; Pressing reset key 10 on housing 8 surfaces can show zero-bit in display screen 12, press shift key 11 and will carry out the unit change to showing numerical value.
Chi body portion as shown in Figure 2 is made up of end chi 13 and connecting plate 14 and the guide plate 16 that has a stator 17 and is fixedly coupled the chi body.Microscope base 23 is fixed on slide plate chair 9 sides, and dwang 19 makes lens barrel 21 unitary rotation in the cover in the rotor plate 20, aims at the mark with gun sight 22.
During use, elder generation is with the required measurement target of chamfered edge rough alignment of end chi 13, take-off the brake is taken turns 1 moving slide board seat 9, by gun sight 22 index 7 is overlapped roughly with target, locking braked wheel 1 back rotary micromotion wheel 3 makes index 7 and target inregister, and presses reset key 10 make display screen 12 show zero-bits on housing 8.The take-off the brake wheel 1 once more, and when moving slide board seat 9 made the index 7 aligning other ends survey target, 12 of display screens showed displacement, by repeating above-mentioned micromethod, can directly read measurement numerical value.
