Abstract
The utility model relates to a pottery brick roughness, crookedness, angularity apparatus, it includes the square ruler of a straight length scale of taking, two fulcrums that can remove, a percentage table test point of fixing in the middle. The two movable supporting points are installed at the left end and the right end of the straight square ruler with the length scales, the dial indicator test points are fixed at the middle point of the straight square ruler with the length scales, and according to the principle that two points on a plane are in a straight line, the surface flatness test ruler is used for fixing screws of the dial indicator test points after the readings of the dial indicator test points are debugged on the surface of a standard working table. This surface flatness test warp chi just can test out unknown surface flatness error numerical value directly perceivedly, and the effect is improving the efficiency of traditional plane flatness test, and traditional leveling ruler is put on the surface object of being surveyed and is tested out the error numerical value of roughness with the feeler gauge, and this kind of traditional approach is inefficient, the degree of accuracy is poor.
Description
Technical Field
The utility model relates to a surface smoothness, crookedness, angularity test field especially relate to the instrument deformation chi field of test surface smoothness test.
Background
The deformation tool for testing the surface flatness is previously carried out by using a feeler gauge, a leveling gauge is placed, the feeler gauge is plugged into the bottom surface of the leveling gauge to test the size of a gap position, the thickness specification of the feeler gauge needs to be changed for multiple times for testing, the working efficiency is low, and the accuracy deviation is large. Therefore, in order to solve the problems, the utility model uses the digital display dial indicator ruler to display, and the digital display dial indicator ruler is directly put on the leveling surface to know the deformation difference of the leveling surface, thereby reducing the labor intensity and improving the working efficiency.
Disclosure of Invention
The utility model discloses aim at solving the loaded down with trivial details of current surface smoothness test, the error is big, the problem of inefficiency, and provide a simple and easy, quick surface smoothness test's utility model surface smoothness test deformation chi, this surface smoothness test deformation chi has adopted the square ruler that has the length scale, there is stable non-deformable's characteristics, the check point is on the central point of this ruler, adopt digital display percentage table to show the numerical value of deformation, the reading is directly perceived, the error bias value can be seen immediately, current work efficiency has been improved. The movable fixed points are designed on the supporting points at the two sides, and the longest (widest) position of the detectable plane can be determined at any time according to the size of the detectable plane for testing.
The ceramic tile flatness, curvature and warping degree tester is characterized by comprising a surface flatness test deformation ruler, wherein the surface flatness test deformation ruler comprises a straight square ruler with length scales, two movable supporting points and a fixed middle dial indicator test point; the surface flatness test deformation ruler is characterized in that two movable supporting points are arranged at the left end and the right end of a straight square ruler with length scales, and a hole is formed in the middle of the straight square ruler to install a dial indicator test point; the surface flatness test deformation ruler is placed on a standard working table, and zero numerical values of test points of the dial indicator can be debugged.
The beneficial effects of the utility model reside in that the utility model provides a test operation is simple and easy, makes the operation mode of original complicacy become simple and easy convenience. On the basis, the digital display type dial indicator is used, so that the zero adjustment is more convenient and quicker, the precision is improved, the numerical value is clear at a glance, the working efficiency of workers is improved, and errors caused by operation are reduced.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
As shown in fig. 1: a fulcrum 3 and a fulcrum 4 are arranged on a square ruler 2 with straight scales, the distance between the fulcrum 3 and the fulcrum 4 is well positioned according to the size of an object to be detected, the distance is close to the size of the object to be detected and is slightly less than 20 mm. Then the screw 6 on the fulcrum 3 and the screw 5 on the fulcrum 4 are locked, so that the position of the square ruler 2 with the fulcrum fixed on the straight scale cannot be changed or loosened at will. The leveling ruler is placed on a standard plate 8, the dial indicator 1 is placed at the middle point of the square ruler 2 with the flat scales, the fastening screw 7 is loosened, the height of the dial indicator 1 is adjusted to enable the reading of the thimble of the dial indicator 1, which is pressed against the standard plate 8, to be +5, then the fastening screw 7 is locked, the dial indicator 1 is fixed and cannot move up and down freely, and only the thimble can move up and down freely. Then, the zero setting button of the dial indicator 1 is set to zero, so that the flatness reading of the dial indicator 1 on the standard plate 8 is zero, and the flatness of the sample can be detected by the leveling ruler.
The 'leveling ruler' of the dial indicator 1 is well adjusted on the standard plate 8 and is placed on the surface of a sample (to be measured), the reading of the dial indicator 1 can be read, the display value is seen, the display value is positive, the sample is bent upwards (bending degree), and the display value is negative, the sample is bent downwards (bending degree). The calculation is by direct reading or by displaying the value divided by the length, i.e. the percentage is expressed as:
tortuosity =
X 100% warpage =
×100%
Δ C: the dial indicator reads the values mm D, length delta W: dial indicator reading value mm
