Detailed Description
The technical scheme of the utility model is described in detail by examples 1 and 2:
example 1
As shown in fig. 1 and 3, the utility model comprises a gauge block body 1, wherein a cutter blade is arranged on the gauge block body 1, two cutter blade surfaces 2 of the cutter blade opening are provided with strip-shaped grinding lines, the strip-shaped grinding lines are perpendicular to the cutting edge lines of the cutter blade, an included angle formed by the two cutter blade surfaces 2 is a cutter blade wrap angle of the gauge block body 1, and the value of the angle of the cutter blade wrap angle ranges from 15 degrees to 70 degrees.
The specific structure of the edge wrap angle laser tester is shown in the DBA-1 series blade edge angle tester.
Although the range of the knife wrap angle laser tester is large and is determined by the length of the arc dial, the wrap angle of the knife edge of a general detected knife is generally not more than 70 degrees, and the wrap angle of the knife edge of a slicing knife is generally not less than 15 degrees, so that the range of the angle value of the knife edge wrap angle is selected to be 15-70 degrees.
The gauge block body 1 may be manufactured from rolling bearing steel GCr15 or alloy tool steel CrWMn, so that the hardness of the blade surface 2 is not less than 63HRC.
It should be noted that, during actual installation, the cutting edge of the gauge block body 1 is parallel to the scale marks on the arc scale disc, and at this time, the grinding lines on the cutter edge surface 2 are horizontal to the laser emitted by the laser source, so as to prevent the arc lines from trailing when the laser interferes and diffracts, thereby effectively reducing the error of reading.
In the embodiment, the thickness of the gauge block body 1 is 1 mm-2 mm, the edge opening of the gauge block body 1 is provided with a blunt surface, the width of the blunt surface is 0.25 mm-0.5 mm, and the cross section of the knife edge is trapezoid, so that the knife edge is prevented from being damaged due to collision.
In this embodiment, the surface roughness of the blade face 2 is not more than 0.63 μm, and the flatness tolerance of the blade face 2 is not more than 0.2 μm.
In this embodiment, the length of the blade opening of the gauge block body 1 is greater than 10mm.
The application process of the utility model is as follows: the method comprises the steps of selecting a gauge block body 1 with at least three angle values of blade wrap angles consistent with the range of a tested blade wrap angle laser tester, sequentially installing the gauge block body 1 on the tested blade wrap angle laser tester to measure the angles of blade faces 2, respectively measuring the angle values of two blade faces 2 of one gauge block body 1, and after laser of the tested blade wrap angle laser tester is reflected by the blade faces 2, setting an arc line which is in an arc dial and is arched away from zero scale marks in the shape, wherein the value of the scale mark tangent to the outer side of the arc line is the angle measurement value of the current blade face 2, and the sum of the angle measurement values of the two blade faces 2 is the blade wrap angle measurement value of the gauge block body 1. And finally, calculating an indication error according to the measured value of the edge wrap angle and the nominal value of the edge wrap angle of the gauge block body 1.
Example 2
As shown in fig. 2, in this embodiment, unlike embodiment 1, there is:
the length of the blade opening of the gauge block body 1 is 5-10 mm, and the gauge block body 1 is embedded on the metal mounting plate 3.
