Description
Technical Field
The application relates to a measuring method and a measuring device for a blade.
Background
In the prior art, the measurement mode of the cutting hard blade is to record an initial value input during tool changing, and a machine table only records a numerical value input by personnel without fool-proof measures; since the initial value of the blade used secondarily is recorded by personnel, the blade used secondarily in the current mode has a large risk of error, and the current measurement mode cannot ensure that the measured variable quantity is the variable quantity in the diameter direction, so that errors may exist.
Currently, the measurement methods for hard and soft blades are as follows:
1. as shown in fig. 1 (a), the hard blade measurement method: the cutter is changed by fixing the cutter blade 10 'on the main shaft 20' and inputting the initial length of the cutter blade; the blade 10 'can only move along the main shaft direction O', the measuring sensor 30 'is positioned below the moving direction of the blade 10', the blade 10 'moves to the upper part of the measuring sensor 30' during the first measurement after the tool change (left diagram in fig. 1 (a)), and then the voltage of the measuring sensor 50 'is lowered until the voltage of the measuring sensor 50' reaches a set value (right diagram in fig. 1 (a)), wherein the voltage of the measuring sensor 50 'reaches the set value, namely the measuring sensor 50' detects the outer edge of the blade 10', and the position of the main shaft 20' at the moment is recorded; the subsequent measurement is compared with the initial measurement by comparing the amount of change in position of the spindle 20' twice, thereby obtaining a new blade length. The blade edge length is calculated as follows:
blade length = last measured blade length-spindle position change, first measured blade length is a human input value.
2. The measuring method of the soft blade comprises the following steps: as shown in fig. 1 (b), the initial input value for soft blade changing is the blade diameter, and the machine automatically calculates the initial blade length (which is related to the diameter of the blade 10 'and the outer diameter of the outer flange 31'), and the remaining measurements are consistent with a hard blade. The calculation formula of the initial edge length is as follows:
initial blade length= (blade diameter-outer flange outer diameter)/2.
The blade edge length is calculated in the same manner as for the hard blade.
From the above, the measurement method of the blade in the prior art has the following problems:
1. the numerical value input by a default personnel of the machine table when the blade is replaced is the initial value of the blade, and fool-proof measures are not provided;
2. the bottommost part of the blade and the center of the sensor cannot be guaranteed to be on a vertical line, and errors exist;
3. the risk of blade reuse is greater.
Therefore, how to accurately measure the actual blade edge length is a problem to be solved in the art.

The embodiment provides a blade measuring method and device, electronic equipment and a readable storage medium.
Fig. 2 is a flowchart of a measuring method of the blade proposed in the present embodiment. The blade measuring method is used for measuring the actual blade length of the blade, and the blade to be measured is arranged on the main shaft in a penetrating mode and is fixed on the main shaft through the flange. As shown in fig. 2, the measuring method of the blade includes the following steps:
step 100: acquiring position data of the flange on the blade to be measured, which is detected by a first positioning sensor, and judging whether the blade to be measured is positioned at a position to be measured according to the position data, wherein the position to be measured is the position of the blade to be measured when the tangent line of the flange is coincident with the axis of the first positioning sensor;

step 300: and calculating the actual blade length of the blade according to the first position data, the second position data and the radius of the flange, wherein the actual blade length is the difference between the radius of the blade to be measured and the radius of the flange.
According to the blade measuring method, the first position and the second position of the outer edge of the blade positioned by the tangent line of the flange positioned at the fixed position on the blade are detected under the condition that the blade to be measured is positioned at the position to be measured, and the actual blade edge length of the blade can be accurately calculated according to the first position data corresponding to the first position, the second position data corresponding to the second position and the radius of the flange. The measuring method of the blade can directly measure the actual blade length of the blade, and avoid the risk of error initial input of the blade; the risk of confusion of the initial value of the secondary utilization of the blade is avoided; the measuring error caused by the position deviation of the blade and the sensor is reduced.
It should be noted that, the flange is abutted to the outer surface of the blade to be tested, and the flange may be disposed at the outer side or the inner side of the blade to be tested, or may be disposed at both sides. And the position to be measured corresponds to the flange, and when flanges are arranged on two sides of the blade to be measured, one flange is taken as the flange for positioning the position to be measured.
In the present embodiment, the measuring device for the blade includes an outer flange 31 located at the outer side of the blade 10 to be measured, and an inner flange 32 located at the inner side of the blade 10 to be measured, and the outer flange 31 located at the outer side of the blade 10 to be measured is used as a positioning flange.
Specifically, as shown in fig. 3 (a) -3 (d), the measuring method of the blade of the present embodiment includes:
in step 100, as shown in fig. 3 (a) and 3 (B), position data of the outer flange 31 detected by the first positioning sensor 40 on the blade 10 to be measured is obtained, and whether the blade 10 to be measured is located at a position a to be measured is determined according to the position data, where the blade 10 to be measured is located when a tangent line B of the outer flange 31 coincides with an axis U of the first positioning sensor 40.
As shown in fig. 3 (a), in the present embodiment, the main shaft 20 is disposed along a first direction X; the first positioning sensor 40 is disposed along a second direction Y perpendicular to the first direction X; the second positioning sensor 50 is disposed parallel to the spindle 20, i.e., the second positioning sensor 50 is disposed along the first direction X.
And during the measurement, the first positioning sensor 40 and the second positioning sensor 50 are located in the same plane.
As shown in fig. 3 (b), in step 100, the first positioning sensor 40 and the second positioning sensor 50 are driven to move relative to the blade 10 to be measured along a third direction Z perpendicular to the plane in which the first direction X and the second direction Y are located, or the spindle 20 is driven to move the blade 10 to be measured relative to the first positioning sensor 40 and the second positioning sensor 50.
Wherein, in the step of determining whether the blade 10 to be measured is located in the position a to be measured according to the position data, the method includes: in the third direction Z, it is determined whether the value of the position data is changed during the process of driving the first positioning sensor 40 to move relative to the blade 10 to be measured. Wherein, determining whether the value of the position data of the outer flange 31 on the blade to be measured 10 changes means that, in the process of driving the first positioning sensor 40 to move relative to the blade to be measured 10, the first positioning sensor 40 detects the geometric shape change at the junction of the blade to be measured 10 and the outer flange 31, so as to ensure that in the next step, the detection position to be detected by the second positioning sensor 50 is accurately on the tangent line B of the outer flange 31. That is, if the position data changes, the first positioning sensor 40 detects the outer flange 31 on the blade 10 to be measured; the position data is unchanged, the first positioning sensor 40 does not detect the outer flange 31 on the blade 10 to be measured.
Specifically, in the process of driving the first positioning sensor 40 to move relative to the blade 10 to be measured by the first driving component 71, whether the numerical value of the position data changes is determined. It should be noted that, since the first positioning sensor 40 and the second positioning sensor 50 are located in the same plane, in the process of driving the first positioning sensor 40 to move relative to the blade 10 to be measured by the first driving assembly 71, the second positioning sensor 50 and the first positioning sensor 40 move synchronously, which can be achieved by driving both the first positioning sensor 40 and the second positioning sensor 50 by the first driving assembly 71, or can be achieved by other methods.
For better illustration, fig. 3 (a) is a process flow diagram in the front view direction, and fig. 3 (b) is a process flow diagram in the side view direction.
In other embodiments, it may also be determined whether the numerical value of the position data changes in the process of driving the spindle to drive the blade to be measured to move relative to the first positioning sensor. And judging whether the numerical value of the position data changes or not in the process that the first driving assembly drives the spindle to drive the blade to move relative to the first positioning sensor.
In step 200, as shown in fig. 3 (C), when the insert 10 to be measured is located at the position a to be measured, data corresponding to a detection position C detected by the second positioning sensor 50 is acquired, the detection position C is two intersection positions of a tangent line B of the outer flange and the outer edge of the insert 10 to be measured, and is denoted as a first position C1 and a second position C2, and the data corresponding to the detection position C includes first position data corresponding to the first position C1 and second position data corresponding to the second position C2.
In step 200, it includes: along the second direction Y, the driving spindle 20 drives the blade 10 to be tested to move relative to the second positioning sensor 50, so that the second positioning sensor 50 measures the first position data and the second position data.
Specifically, along the second direction Y, the spindle 20 is driven by the second driving component 72 to drive the blade 10 to be tested to move relative to the second positioning sensor 50, so that the second positioning sensor 50 measures the first position data and the second position data.
In this embodiment, the second positioning sensor 50 is located below the blade 10 to be measured, and in the process that the second driving assembly 72 drives the spindle 20 to drive the blade 10 to be measured to move downward along the second direction Y, the first position c1 and the second position c2 on the blade 10 to be measured sequentially pass through the second positioning sensor 50, so that the first position data corresponding to the first position c1 and the second position data corresponding to the second position c2 can be obtained through voltage variation.
In other embodiments, the second positioning sensor may be driven to move relative to the blade in the second direction Y, so that the second positioning sensor measures the first position data and the second position data. The second positioning sensor may be driven by the second drive assembly to move relative to the blade such that the second positioning sensor measures the first and second position data.
In step 300, the actual edge length of the blade 10 to be measured is calculated according to the first position data, the second position data and the radius of the outer flange 31, wherein the actual edge length is the difference between the radius of the blade 10 to be measured and the radius of the outer flange 31.
As will be understood in conjunction with fig. 3 (d), the actual blade length is calculated as follows:
where L is the actual blade length, r is the radius of the outer flange 31, and H is the absolute value of the difference between the first position data and the second position data.
For better illustration, fig. 3 (c) is a process flow diagram in the front view direction, and fig. 3 (d) is a process flow diagram in the side view direction.
According to the measuring method of the blade, the actual blade length is directly obtained by adopting a new measuring mode, and meanwhile, the error of measurement is reduced by adopting a plurality of sensors, namely, the measured position can be ensured by adopting the combination of the first positioning sensor and the second positioning sensor, so that the error is reduced; the measuring method of the blade is not only suitable for measuring the actual blade length of the hard blade, but also suitable for measuring the actual blade length of the soft blade.
As shown in fig. 4 to 6, the present embodiment further provides a measuring device for a blade, where the measuring device is used for measuring an actual edge length of the blade, and the blade 10 to be measured is disposed on the spindle 20 in a penetrating manner and is fixed on the spindle 20 by a flange, and the measuring device for a blade includes: a first positioning sensor 40, a second positioning sensor 50, and a processor 60.
