Abstract
The invention discloses a testing method for the radian of an end cover, comprising the following steps: 1) preparing and putting the end cover needing to be tested and a size measuring unit on a horizontal platform surface; 2) using the size measuring unit to find any diameter on the end cover and marking the diameter with a marking pen by drawing a line; 3) marking an intersected point between the line and the edge of the end cover as a point B, marking the points at every unit distance till a point A at the tail of the radian is marked; 4) using a height measuring unit to carry out a test on the distance between the point and the horizontal platform surface from A to B along each point and recording data; 5) taking the distance L from the point to the edge as a horizontal coordinate, taking the height H from the point to the horizontal platform surface as a longitudinal coordinate, and drawing a radian curve of the end cover correspondingly; 6) testing height data from the point A to the point B in a drawing of the end cover, and using an Excel table to make a standard curve; and 7) comparing two curves and determining whether the radian of the end cover meets the requirements of the drawing. The testing method has the beneficial effects that due to utilization of the method disclosed by the invention, the conformity between the size of the end cover and the drawing can be observed very intuitively, and the actual deviation of production is less.
Description
Technical field
The present invention relates to a kind of method of testing of end cap radian, belong to sun power end cap quality inspection technical field.
Background technology
In the end cap dimensional measurement, some size for example height, length, diameter is to be easy to test out, also some critical size for example radian be difficult to measure, but the size of its radian has influence on the quality of production.
End cap producer produces end cap through processing corresponding mould behind the rendering computer figure, because the part resilience takes place after the end cap moulding, processing rear end cap and drawing are designed with certain deviation.If the height of the end cap radian after the resilience is littler than the die cavity of foaming, and it is not in place to be prone to cause end cap to fasten, and forms bigger slit, and is bigger to the presentation quality influence.Therefore whether satisfy dimensional requirement if how to assess the end cap radian, important.
Whether traditional assessment end cap radian satisfies the dimensional requirement method is: carry out line cutting processing model according to drawing requirement, put into end cap inner chamber test radian and whether meet the demands, if model can be put into end cap fully, and seamless just can judge meet drawing; Otherwise end cap and drawing do not meet.Through test, this kind mode detects qualified end cap, and produces the actual bigger deviation that has.And check out improper end cap, also be difficult for instructing end cap how to change and can satisfy production requirement.
Summary of the invention
The present invention is directed to the problem of producing with bad measurement of end cap radian and assessment, provide a kind of and the production actual deviation little, and the method for testing of the high end cap radian of efficient.
The present invention adopts following technical scheme:
A kind of method of testing of end cap radian is characterized in that, may further comprise the steps:
1) need to be ready to the end cap and the dimensional measurement unit of test to be placed on the level table;
2) use the dimensional measurement unit seek any diameter on the end cap and on end cap with marking pen setting-out mark;
3) be denoted as the B point at the crossing point of above-mentioned setting-out and end cap edge, every at a distance from the unit distance punctuate, the A point up to the end of radian;
4) use height measurement unit to carry out test point to level table distance and record data to B along each point from A;
5) being horizontal ordinate to put Edge Distance L, is ordinate to put the level table height H, and correspondence is drawn out end cap radian curve;
6) in the end cap drawing, test out the altitude information that the A point is ordered to B, and use the Excel form to make typical curve;
7) two curves are compared, judge the matching degree of end cap measured data and drawing, confirm whether the end cap radian meets drawing requirement.
Consider easy to usely, said dimensional measurement unit is the 500mm slide calliper rule, and height measurement unit is a height gauge.
Principle of work of the present invention:
The end cap radian is carried out pointwise test and tests the end cap height,, end cap curve and drawing typical curve are compared, confirm whether its radian of end cap meets drawing requirement with excel form curve plotting.Propose the degree of conformity of end cap size and drawing targetedly, change the end cap size.
Beneficial effect of the present invention:
Utilize method of the present invention can observe the degree of conformity of end cap size and drawing very intuitively, and the production actual deviation is little.
Description of drawings
Fig. 1 is the test synoptic diagram of end cap radian of the present invention.
Fig. 2 is former method end cap size, the inventive method end cap size and figure paper size correlation curve figure.
Actual end cap size of Fig. 3 the inventive method and figure paper size correlation curve figure.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is explained further details, following explanation only is exemplary.
A kind of method of testing of end cap radian may further comprise the steps:
1) need to be ready to the end cap and the 500mm slide calliper rule of test to be placed on the level table;
2) with reference to accompanying drawing 1, use the 500mm slide calliper rule seek any diameter on the end cap and on end cap with marking pen setting-out mark;
3) with reference to accompanying drawing 1, be denoted as the B point at the crossing point of above-mentioned setting-out and end cap edge, every at a distance from the unit distance punctuate, the A point up to the end of radian;
4), use height to carry out test point to level table distance and record data to B along each point from A with reference to accompanying drawing 1;
5) with reference to accompanying drawing 1,2 and 3, be horizontal ordinate to put Edge Distance L, be ordinate to put the level table height H, correspondence is drawn out end cap radian curve;
6), in the end cap drawing, test out the altitude information that the A point is ordered to B, and use the Excel form to make typical curve with reference to accompanying drawing 1,2 and 3;
7) two curves are compared, judge the matching degree of end cap measured data and drawing, confirm whether the end cap radian meets drawing requirement.
Said dimensional measurement unit is the 500mm slide calliper rule, and height measurement unit is a height gauge.
Be below an end cap on diverse location, end cap figure paper size, former method end cap size and new method end cap size such as table 1:
