Embodiment 1

[0047] Such as Figure 2-4 Shown, a kind of circular arc grinding wheel dresser nib rotation radius measuring instrument, including

[0048] The base 1 is fixed with a "U"-shaped measuring platform 2, and one end of the "U"-shaped measuring platform 2 is provided with a Y up-down adjustment device 6.1 and an X left-right adjustment device 6.2.

[0049] The Y up and down adjustment device 6.1 and the X left and right adjustment device 6.2 are provided with a mirror holder 6, and the Y up and down adjustment device 6.1 and the X left and right adjustment device 6.2 are provided with a linear measuring device, which can clearly display the moving distance of the microscope 5 during use.

[0050] Microscope 5 is housed on the mirror base 6, and the central optical axis of the reticle of microscope 5 is C2-C2 ', as Figure 4 As shown, the microscope 5 is set horizontally, and the Y up and down adjustment device 6.1 and the X left and right adjustment device 6.2 control the up, dow...

Embodiment 2

[0055] Such as Figure 5 as shown,

[0056] A method for correcting left and right centering of a trimming nib, comprising

[0057] Make the central optical axis C2-C2' of the crosshair of the microscope always parallel to the rotation axis C1-C1' of the grinding wheel dresser;

[0058] Adjust the focus of the microscope so that the dressing tip of the grinding wheel dresser is clearly imaged on the microscope;

[0059] Rotate the trimming pen left and right by 90°, observe and adjust the highest point of the trimming pen tip in the microscope, so that the highest point of the trimming pen tip on the left and right sides is at the same height or on the same horizontal line; when adjusting, use the principle of 180°rotation of eccentricity error twice , so to adjust the highest point of the pen tip, it should be adjusted back half of the display distance, until the left and right rotation of the trimmed pen tip is 90°, the highest point of the pen tip is on the same horizonta...

Embodiment 3

[0061] A method for measuring the radius of rotation of a trimming nib, comprising

[0062] Place the grinding wheel dresser that needs to be adjusted in the installation step or chute, so that the central optical axis C2-C2' of the crosshair of the microscope is always parallel to the rotation axis C1-C1' of the grinding wheel dresser,

[0063] Adjust the focus of the microscope so that the dressing tip of the grinding wheel dresser is imaged on the microscope;

[0064] Rotate the trimming pen left and right by 90°, observe and adjust the highest point of the trimming pen tip in the microscope, so that the highest points of the trimming pen tip on the left and right sides are at the same height or on the same horizontal line;

[0065] Rotate the pen tip 90° to the left, adjust the cross measuring line of the microscope through the X left and right adjustment measuring device, make the vertical line of the cross measurement line coincide with the highest point of the pen tip, ...

Abstract

The invention discloses an arc grinding wheel dresser nib rotation radius measuring instrument and a measuring method thereof, and solves the left-right centering problem of a dressing pen on a correction arc dresser through microscope observation and adjustment by utilizing the left-right rotation characteristic of a grinding wheel dresser. Because the X left-right adjusting device can clearly display the moving distance of a microscope, the dressing radius R of the dressing pen point can be directly, quickly and accurately read out from the X left-right adjusting device.

Description

technical field [0001] The invention belongs to the field of precision instrument adjustment, and in particular designs an instrument for measuring the radius of rotation of a nib of an arc grinding wheel dresser and a measuring method thereof. Background technique [0002] When performing performance tests on tensile endurance test pieces, impact test pieces, fracture toughness KIC test pieces, crack growth test pieces, etc., it is necessary to process a 30° or 45° or 60° V-shaped notch or U-shaped on the sample material gap. The tip of the notch is generally a circular arc R transition. The radius of the transitional arc R needs to be accurate in size, and the apex position of the transitional arc R also needs to be accurate, in order to measure the real characterization data of the material. [0003] And this kind of gap arc R, most of the size is small; the radius of the arc R is mostly in the range of R1mm-R0.1mm. When the above-mentioned R value is trimmed by the ar...
