Abstract
The utility model provides an auxiliary measurement device of a LinTab series annual ring analysis instrument, which is mainly used for the auxiliary measurement of wood annual ring ribs and discs and used in the technical field of dendrochronology. On account of the defects that fixing and adjusting devices are not arranged for the class of instruments and accurate horizontal shift cannot be realized, the utility model can efficiently, conveniently and accurately realize the auxiliary measurement of annual rings and has the characteristics of firmness, durability, low price, high safety, easy material acquisition, simple structure and convenience of popularization. The main body material of the auxiliary measurement device is tailored alloy aluminium panels. The main body consists of four layers from top to bottom: a base, a lower disc, an upper disc and a top fixing device. Through the exchange of the top fixing device, the wood annual ring ribs and discs are alternately measured. The lower disc is rotated to realize a rotating function, and an upper screw and a lower screw are rotated to realize horizontal shift. When the auxiliary measurement device is used for geometry correction measurement, a lever indicator is fixed on an LinTab base, so that a measurement rod is in tight contact with one end of the lower screw.
Description
Technical field
The utility model is mainly used in subsidiary tree ring bar and disk, is applied to the Dendrochronology technical field.
Background technology
At present, LinTab series analysis of annual rings instrument is one of main flow instrument of measuring in the world wide tree ring width, and its standard resolution is 1/100mm, because of its flexible operation, precision height enjoy the professional person to favor.The base program of measuring is: will polish good tree ring bar or disk are placed on the square operator's console that specification is 30cm * 30cm, adjust microscope, by the operator's console occurred level displacement on the turning handle drive track, utilize " crosshair " mark annual ring late wood's the previous year in the eyepiece and the boundary line between back 1 year early wood, thereby reach the wide purpose of record wheel.Its shortcoming is: (1) operator's console lacks the device of fixing annual ring bar or disk, because microscopical enlargement factor is bigger, " crosshair " departed from the careless slightly annual ring border that will make in the measuring process, even exceeds microscopical field range, has a strong impact on efficiency of measurement; (2) operator's console lacks the device of regulating annual ring bar or disk position, in measuring process, tangent for guaranteeing " crosshair " and annual ring border, need constantly, by a small margin, multi-angle adjustment annual ring bar (360 °), the varying level direction or the position of disk, because staff directly contacts annual ring bar or disk, adjustment process exists very big subjectivity and randomness, be difficult to realize tangent degree consistent of each annual ring border and " crosshair ", bigger personal error be can produce therebetween, measurement result and follow-up fixed year of intersection directly influenced; (3) can't be implemented in precise displacement on the horizontal direction vertical with track running direction; for quite a few annual ring bar; two adjacent late wood borders through regular meeting present "/" or “/" etc. irregularly shaped; be difficult in the measuring process accept or reject; for guaranteeing measuring accuracy; just need measure twice at least to carry out geometry correction; thisly repeat not to be that simple machinery repeats; but need on the horizontal direction vertical, realize precise displacement with track running direction, this device wouldn't possess this function.
Summary of the invention
In order to remedy the shortcoming that lacks fixing and regulating device and can't realize accurate horizontal shift, the utility model provides a kind of aided measurement device of LinTab series analysis of annual rings instrument, this device can be efficiently, convenient, accurately auxiliary year a wheel measurement.
The technical scheme that its technical matters that solves the utility model adopts is: the material of main part of aided measurement device is special alloy aluminium sheet.Main body is made up of four parts, is respectively from the bottom to top: base, lower disc, last disk, top fixture.The chassis specification is that a length is 30cm, and width is 30 cm, and thickness is the rectangular parallelepiped of 1.5cm, and the center is that a diameter is 10cm, and thickness is the penetrating circular hole of 1.5cm, is used to install lower disc.The lower disc bottom is that a diameter is 10cm, and thickness is the cylinder of 1cm, is embedded on the base, and realizes 360 ° spinfunction with this; Lower disc top is that a diameter is 20cm, thickness is the cylinder of 2cm, surperficial thereon centre position from top to bottom is that a length is 18.4cm, width is 2.4cm, it highly is the rectangular channel of 1.6cm, this groove is used to install down screw rod and sliding block, and realizes displacement on the horizontal direction vertical with the annual ring bar with this.Last disk is that a diameter is 14cm, thickness is the cylinder of 2cm, in its lower surface centre position is that a length is 12.4cm from the bottom to top, width is 2.4cm, it highly is the rectangular channel of 1.6cm, this groove is used to install screw rod and top shoe, and realizes displacement on the horizontal direction parallel with the annual ring bar with this.By the be connected interlock that realize go up disk and lower disc of top shoe with sliding block.Top fixture is divided into two kinds, and a kind of is the movable clip slot that can regulate width, is used for fixing the annual ring bar, and a kind of is that the surface has 3 dismountable top roundels, is used for fixing the annual ring disk.Top fixture is fixed on the disk by screw.Fix a lever indicator on the LinTab pedestal, drop shot one end closely contacts with measuring staff, thereby realizes the precise displacement of annual ring bar on the horizontal direction vertical with track running direction.
During use this device is fixed on the LinTab operator's console by special clamp, tree ring bar or disk are fixed on the top fixture, realize spinfunction, by rotating the displacement on the upper and lower screw rod realization horizontal direction by the rotation lower disc.
The beneficial effects of the utility model are: can strengthen the steadiness of annual ring bar in the measuring process or disk, avoid because the skew of the annual ring that causes of accidentally dropping improves the efficient of measuring; Can farthest overcome staff and directly contact subjectivity and the randomness error that causes, horizontally rotating and displacement of realization annual ring nimbly and freely improves measuring accuracy; Can realize perpendicular to the precise displacement on the horizontal direction of track, thus the needs that meeting geometric is proofreaied and correct.In addition, this device is solid, durable, cheap, safety, is easy to draw materials, and is simple in structure, is convenient to popularize.
