Abstract
The utility model relates to a tool for measuring a polycrystalline silicon rod chamfer. The tool comprises a scale plate and scale on the scale plate; the scale plate is provided with at least one row of scale; each row of scale are of different widths and are arranged in parallel on the scale plate in a narrow-wide manner; the widths of rows of scale are increased progressively from a lower limit value of a chamfer width range to an upper limit value of the chamfer width range with 0.01 mm as unit. The tool provided by the utility model is advantaged in that: the tool is adopted to perform comparison with the silicon rod chamfer to find out a comparison scale closest to the width of the silicon rod chamfer as a measurement value; a comparison scale range is from 0.5 to 2 mm, and the comparison scale is decreased progressively within the comparison scale range; further, the tool is simple, convenient and is capable of accurately measuring a size.
Description
Technical field
The utility model relates to a kind of polycrystalline silicon rod chamfering and measures frock.
Background technology
When measuring the chamfering size, use common ruler after existing polycrystalline silicon rod chamfer machining is accomplished, minimum scale is 1mm, and silicon rod chamfering size specification value is 0.5-2mm.Measurement data need be estimated and reads in the practical operation, and error is bigger.And when more than 2 people, measuring, the data judging deviation strengthens, and is prone to controversial.
The utility model content
The utility model technical matters to be solved is: provide a kind of polycrystalline silicon rod chamfering to measure frock, reduce measured value and estimate the error of reading to produce, make measurement data more accurate, avoid a dispute.
The utility model solves the technical scheme that its technical matters adopted: a kind of polycrystalline silicon rod chamfering is measured frock; Comprise the scale on scaleplate and the scaleplate; Scaleplate is provided with row's scale at least; The width of the scale among each row is all different, on scaleplate, arranges abreast successively from narrow to wide, and it is the higher limit that unit is incremented to the chamfering width range successively that the width of scale begins with 0.1mm from the lower limit of chamfering width range.
Scaleplate is a rectangle, and scale is divided into two rows on the surface of scaleplate, two row's scale horizontal symmetrical.
The pros and cons two sides of scaleplate all has scale.
The beneficial effect of the utility model is: through use this measurement frock and silicon rod chamfering the comparison, find out with the immediate contrast scale of silicon rod chamfering as measured value.Comparison meter full scale: 0.5-2mm, the comparison scale increases progressively with 0.1mm in the scope.Simply, convenient, can accurately measure size.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified;
Fig. 1 is the front elevation of the utility model;
Fig. 2 is the side view of the utility model;
Among the figure, 1. scaleplate, 2. scale.
Embodiment
As illustrated in fig. 1 and 2; A kind of polycrystalline silicon rod chamfering is measured frock; Comprise the scale 2 on scaleplate 1 and the scaleplate 1, scaleplate 1 is provided with row's scale at least, and the width of the scale 2 among each row is all different; On scaleplate 1, arrange abreast successively from narrow to wide, it is the higher limit that unit is incremented to the chamfering width range successively that the width of scale 2 begins with 0.1mm from the lower limit of chamfering width range.
The lower limit of chamfering width range is 0.5mm, and the higher limit of chamfering width range is 2mm.The width of scale 2 is incremented to 2.0 successively from 0.5,0.6,0.7,0.8,0.9,1.0,1.1,1.2,1.3,1.4,1.5,1.6,1.7,1.8,1.9.
Scaleplate 1 is a rectangle, and scale 2 is divided into two rows on the surface of scaleplate 1, two row's scales, 2 horizontal symmetrical.The pros and cons two sides of scaleplate 1 all has scale 2.
Claims (3)
1. a polycrystalline silicon rod chamfering is measured frock; It is characterized in that: comprise the scale (2) on scaleplate (1) and the scaleplate (1); Scaleplate (1) is provided with row's scale at least; The width of the scale (2) among each row is all different, goes up at scaleplate (1) abreast successively from narrow to wide and arranges, and it is the higher limit that unit is incremented to the chamfering width range successively that the width of scale (2) begins with 0.1mm from the lower limit of chamfering width range.
2. polycrystalline silicon rod chamfering according to claim 1 is measured frock, and it is characterized in that: described scaleplate (1) is a rectangle, and scale (2) is divided into two rows on the surface of scaleplate (1), two row's scale (2) horizontal symmetrical.
3. polycrystalline silicon rod chamfering according to claim 1 and 2 is measured frock, and it is characterized in that: the pros and cons two sides of described scaleplate (1) all has scale (2).
