Description
Technical field
The utility model relates to a kind of caliberating device of displacement meter, is used for the quick demarcation of guy type displacement meter, belongs to instrument class.
Background technology
Guy type displacement meter is that a kind of relative displacement commonly used measures device; Its range commonly used is between the 5mm to 500mm; When laboratory and on-the-spot test, all need check and calibrate, especially in experimental enviroment, usually utilize and manually pull out backguy and utilize steel tape to carry out assisted calibration and demarcation its sensitivity; Not only stated accuracy can't guarantee, operation is very inconvenience also.Carry out routine and calibrate not only that cost is higher and adopt metering to demarcate frame with vernier caliper, the debugging installation period is also longer, demarcates in working order for displacement meter, lacks also simple and effective caliberating device at present.
The utility model content
Based on the problems referred to above, the utility model proposes a kind of guy type displacement meter and demarcates frame fast, and its technical solution is:
Guy type displacement meter is demarcated frame fast; It comprises base 1, equally spaced pilot hole 4, stay column 5, is used for fixing the block 2 of displacement meter, the screw 3 that is used for fixing displacement meter 8 and displacement meter standing screw 7; Have equally spaced pilot hole 4 on the base 1; Base 1 is provided with the block 2 of the convexity of fixed displacement meter in a side of pilot hole 4; The same side of base also has screw 3 away from pilot hole 4 ends, is provided with in the screw 3 to be used for displacement meter 8 is withstood on the displacement meter standing screw 7 on the block 2, through the block 2 of base 1 raising and the screw rod 7 that is installed in the screw 3 displacement meter 8 is fixed on the base 1; Also include one and insert in the stay column 5 that being used in the pilot hole 4 links to each other with displacement meter backguy 6, the extension elongation of regulating displacement meter backguys 6 through the stay column 5 that is installed in the pilot hole 4 is to produce the displacement of confirming difference.
There is an aperture described stay column 5 upper ends, pass one in the hole and are used for the drag hook that displacement meter backguy 6 is passed.
The diameter of described stay column 5 is identical with the internal diameter of pilot hole 4, so that stay column 5 gapless being inserted in the pilot hole 4.
Described stay column 5 can move up and down in pilot hole 4, is in level to guarantee displacement meter backguy 6.
Described pilot hole 4 is linearly equidistantly arranged.
Owing to adopt technical scheme as stated; The utlity model has following advantage: the utility model distance between pilot hole in use is a known quantity; Utilize stay column equidistant moving between pilot hole to realize stretching out or withdrawing of displacement meter backguy measured length; Can under the situation that need not utilize other high precision measurer (like vernier caliper etc.), realize the quick field calibration of guy type displacement meter, and simple structure, easy to use, cost of manufacture is low.

Embodiment
Further specify below in conjunction with the enforcement of accompanying drawing the utility model:
This guy type displacement meter as depicted in figs. 1 and 2 is demarcated frame fast by base 1; Protruding block 2 on the base, base be away from the screw 3 of pilot hole one side, straight equidistant pilot hole 4 on the base; Can not have the gap and insert the stay column 5 in the pilot hole, have 7 formations of certain-length screw rod.
Base 1 can adopt low carbon steel plate, corrosion resistant plate, aluminium alloy etc. to carry out machine work and process; Length needs the work range (generally in 600mm) greater than guy type displacement meter; Its width should slightly be wider than the width of guy type displacement meter 8, and in the block 2 height 5mm, the clear space between block 2 and the screw 3 should guarantee that guy type displacement meter 8 can place therebetween; The general desirable 2-4mm of the diameter of pilot hole 4; Spacing is got 10mm to 50mm according to the guy type displacement meter range, and pilot hole 4 should have an aperture to equidistant arrangement stay column 5 upper ends along the length of base, passes one in the hole and is used for the drag hook that displacement meter backguy 6 is passed; Also can use end sewing needle with holes to replace, the short steel column that also can process different length is subsequent use.Displacement meter backguy 6 can be fixed on the stay column 5 through the drag hook that thin wire is done.
The principle of work that guy type displacement meter is demarcated frame fast is:
Guy type displacement meter is being carried out timing signal; At first guy type displacement meter is placed between block and the screw; Thereby its afterbody that compresses displacement meter is fixed through rotating screw bolt; Connect displacement meter power supply and metric data line, then the free end of displacement meter backguy is connected with stay column and stay column is inserted in the pilot hole of correct position, utilize the output voltage u of multimeter or data acquisition equipment measurement guy type displacement meter
1, move stay column then to another pilot hole, can know that according to the pilot hole spacing displacement meter backguy overhang counts Δ, and then measure the displacement meter output voltage and count u
2, can know that under a proportional relationship the sensitivity coefficient between output voltage and the Displacement Feedback value is k=Δ/(u
2-u
1).Measure through a plurality of pilot holes and can demarcate the linearity of displacement meter in whole range ability, utilize data acquisition equipment to record also can to obtain very easily under the situation of displacement readings value sensitivity correction factor and zero value partially.
