In order to make the technical solution of the embodiment of the present invention better understood, the technical solution of the embodiment of the present invention will be clearly and completely described below with reference to the drawings of fig. 1, 3 and 4, 6 and 7, and 10 and 11.
The embodiment of the invention provides a method for calibrating a rotating shaft of a numerical control machine tool, which comprises the following steps:
again according to the flow chart of figure 1 and the illustrations of figures 3 and 4;
step S100, loading the first vertical plate 1 on a processing platform, controlling the A shaft to drive the cutter to rotate to two sides of the first vertical plate 1, and calibrating the rotation radius of the A shaft by measuring and comparing the distance from the cutter point 4 of the cutter to the first vertical plate 1.
Specifically, this first board 1 of erectting is vertical to be set up on processing platform, and it is rotatory through A axle control module control A axle to the drive is connected and is changeed the both sides of first board 1 of erectting around the X axle in the epaxial cutter of A, and the first distance of erectting board 1 is measured and compared to the knife tip of cutter in first board 1 both sides of erectting respectively, carries out turning radius calibration to the A axle according to both sides distance comparison result.
Again according to the flow chart of figure 1 and the illustrations of figures 6 and 7;
step S200, loading the horizontal plate member 2 on the processing platform, controlling the C axis to drive the cutter to rotate to different positions on the same surface of the horizontal plate member 2, cutting at least two first blocks 21 and a second block 22 surrounding the first blocks 21, and calibrating the rotation radius of the C axis by measuring and comparing the distance from the same side edge of each first block 21 to one side edge of the second block 22 near the side edge of each first block 21.
Specifically, the horizontal plate member 2 is loaded on the processing platform, i.e., the horizontal plate member 2 is horizontally disposed on the working platform. The C shaft is controlled to rotate by the C shaft control module, and the C shaft is connected to the A shaft, so that the C shaft drives the cutter on the A shaft to rotate around the Z shaft when rotating, and the cutter rotates around the Z shaft to different positions on the same surface of the horizontal plate member 2. The machining platform is moved in the direction of the X-axis and/or Y-axis, so that the horizontal plate member 2 is moved in the direction of the X-axis and/or Y-axis and cut by the tool into at least two first boxes 21 and a second box 22 surrounding the first boxes 21. The turning radius calibration is performed on the C-axis by measuring and comparing the distance from the same side of each first frame 21 to a side of the second frame 22 located near the side of each first frame 21, and then based on the comparison results of the frame distances.
Again according to the flow chart of figure 1 and the illustrations of figures 10 and 11;
step S300, loading the second vertical plate 3 on a processing platform, controlling the A shaft to drive a cutter to rotate to two sides of the second vertical plate 3, cutting out a third square frame 31 and a fourth square frame 32 which can be arranged around the third square frame 31, and performing zero position calibration on the A shaft and/or the C shaft by measuring and comparing the distances between the adjacent sides of the third square frame 31 and the fourth square frame 32 in the vertical direction of the second vertical plate 3 and/or in the horizontal direction of the second vertical plate 3.
Specifically, the second erected panel 3 is loaded on the processing platform, that is, the second erected panel 3 is vertically disposed on the processing platform. The rotation of the shaft A is controlled by the shaft A control module, so that the cutter is rotated to two sides of the second vertical plate 3. Since the a axis rotates around the X axis, the processing platform moves in the Y axis and/or X axis direction, so that the second vertical plate 3 moves in the Y axis and/or X axis direction and is cut by the cutter into the third frame 31 and the fourth frame 32 which can be enclosed in the third frame 31, respectively. By measuring and comparing the distance between the adjacent sides of the third frame 31 and the fourth frame 32 in the vertical direction of the second vertical plate 3, the axis A is subjected to zero position according to the vertical distance comparison result; and/or, by measuring and comparing the distance between the adjacent sides of the third frame 31 and the fourth frame 32 in the horizontal direction of the second vertical plate 3, and then performing zero position on the C axis according to the horizontal distance comparison result.
It should be understood that, although the steps in the flowcharts of the figures are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and may be performed in other orders unless explicitly stated herein. Moreover, at least a portion of the steps in the flow chart of the figure may include multiple sub-steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, which are not necessarily performed in sequence, but may be performed alternately or alternately with other steps or at least a portion of the sub-steps or stages of other steps.
Compared with the prior art, the method for calibrating the rotating shaft of the numerical control machine tool at least has the following beneficial effects: the method for calibrating the rotating shaft of the numerical control machine tool aims to provide a system program for calibrating the zero position of the C shaft and the A shaft and calibrating the rotating radius of the C shaft and the A shaft, and is embodied in the following steps:
the calibration of the rotation radius of the A shaft is realized by measuring and comparing the distances from the tool nose 4 of the tool to the first vertical plate 1 when the tool is positioned at the two sides of the first vertical plate 1, and calibrating the rotation radius of the A shaft according to the comparison result.
Calibrating the rotation radius of the C axis by rotating the C axis to make the cutter cut at least two first frames 21 and one second frame 22 at different positions on the same surface of the horizontal plate member 2; and then measuring and comparing the distance from each first box 21 to the same side of the second box 22, and performing rotation radius compensation on the C axis according to the comparison result.
Zero calibration of the A axis and/or the C axis is realized by controlling the rotation of the A axis to enable a cutter to respectively cut a third square frame 31 and a fourth square frame 32 on two sides of the second vertical plate 3; and then measuring and comparing the distances of the adjacent edges at each position of the third frame 31 and the fourth frame 32, and calibrating the zero position of the A axis and/or the C axis according to the comparison result.
In summary, it can be seen from the analysis that the embodiment of the present invention provides a method for calibrating a rotating shaft of a numerical control machine, where a position between the rotating shaft and a plate is changed by rotating an a-axis and a C-axis, distances between the plate and the plate at different positions are measured, or distances between the plate and the plate at different positions after cutting are measured, and a set rotating radius calibration and zero calibration of the a-axis and the C-axis are performed, so that a tool is successfully set, and a phenomenon that a relative position between a tool nose of the tool and an alignment point is observed by naked eyes to estimate a required compensation amount is avoided.
In some alternative implementations of the present embodiment, as shown in fig. 2 to 4, the step of calibrating the turning radius of the a-axis by measuring and comparing the distance from the nose 4 of the tool to the first erected panel 1 specifically comprises:
and S110, measuring the distances from the tool nose 4 of the tool to the two sides of the first vertical plate 1 respectively, and recording the distances as m and n.
And step S120, comparing the values of m and n.
Step S130, if the values of m and n are not equal and are outside the allowable deviation range, calculating a deviation value of the rotating radius of the shaft A and supplementing the deviation value into a processing program so as to calibrate the rotating radius of the shaft A when the shaft A drives the cutter to rotate during cutting processing, thereby obtaining a target value of the rotating radius of the shaft A.
Specifically, the calculated A-axis rotating radius deviation value is supplemented into a processing program, after the processing program obtains the A-axis rotating radius deviation value, the current A-axis rotating radius is supplemented according to the A-axis rotating radius deviation value, so that in the cutting process, when the A-axis drives the cutter to rotate, the cutter processes the workpiece on a correct processing track through the compensation of the A-axis rotating radius deviation value on the original A-axis rotating radius.
And step S140, if the values of m and n are equal or the difference value is within the allowable deviation range, maintaining the current rotating radius of the shaft A when the A shaft drives the cutter to rotate during cutting processing, and taking the current rotating radius of the shaft A as the target value of the rotating radius of the shaft A.
Namely, in the next cutting process, when the A shaft drives the cutter to rotate, the current rotating radius of the A shaft does not need to be changed.
As shown in fig. 2 to 4, in some optional implementations of this embodiment, the step of calculating the deviation value of the rotation radius of the axis a specifically includes:
step S131, measuring the thickness t of the first vertical plate 1 and acquiring a preset reference value S.
And step S132, calculating the deviation value alpha of the rotating radius of the shaft A according to m, n, S and t. It should be noted that the predetermined reference value s is specifically the distance that the tip 4 of the tool should have from the standing plate 1.
Referring to fig. 3 and 4, in particular, in an embodiment of the present invention, in order to better understand the calculation process of the deviation value of the rotation radius of the a-axis, the following formula is specifically illustrated:
alpha is obtained from the values of m, n, t and s. The formula for calculating the deviation value of the rotating radius of the shaft A is as follows:
α＝|m+n-2s-t|/2；
when m is larger than n, alpha is a positive value; conversely, when m < n, α is negative.
The value of alpha obtained by the formula can be supplemented into a processing program so as to calibrate the rotating radius of the shaft A when the shaft A drives the cutter to rotate in the cutting process and obtain a target value of the rotating radius of the shaft A.
According to fig. 3 and 4, in some alternative implementations of the present embodiment, the step of controlling the a-axis to drive the cutter to rotate to the two sides of the first vertical plate 1 specifically includes:
controlling the A shaft to rotate 90 degrees through the A shaft control template, and enabling the cutter to rotate to one side of the first vertical plate 1; the A shaft is controlled to rotate by-90 degrees through the A shaft control template, so that the cutter is rotated to the other side of the first vertical plate 1. It should be noted that the rotation of the a-axis by 90 ° or-90 ° is controlled based on the initial position of the a-axis, which is to ensure that the line between the two positions of the a-axis when rotated by 90 ° and-90 ° is perpendicular to the first upright plate 1.
According to fig. 3 or 4, in some optional implementation manners of this embodiment, a hole 11 may be formed in the first vertical plate 1, and in the step of controlling the shaft a to rotate so that the tool rotates to two sides of the first vertical plate 1, the shaft a is controlled to rotate so that the tool tip 4 of the tool is aligned with the hole 11, and when a vernier caliper is used to measure the distance from the tool tip 4 to the vertical plate 1, the hole 11 may play a role in avoiding a gap in the vernier caliper, so as to facilitate the measurement of the vernier caliper.
In some optional implementations of this embodiment, a sensor may be placed on the nc machine tool near the tool for measuring the distance of the tip 4 of the tool to a measured object, for example, in this embodiment, the sensor may measure the tip 4 to the first upright plate 1.
In some alternative implementations of the present embodiment, the step of controlling the C-axis rotation to rotate the tool to different positions on the same surface of a horizontal plate 2 to cut out four first boxes 21 specifically includes:
after each first frame 21 is cut, the C-axis is controlled to rotate 90 ° to rotate the cutter to the corresponding position on the surface of the horizontal plate member 2, so as to cut the next first frame 21.
As can be understood from fig. 6 or 7, when the C-axis is in the initial state, i.e. the C-axis is rotated by 0 °, the cutter cuts a first square frame 21 at a corresponding position on the surface of the horizontal plate 2; controlling the C shaft to rotate 90 degrees on the basis of the initial position of the C shaft so that the cutter rotates to a position corresponding to the surface of the horizontal plate member 2 to cut a second first square frame 21; on the basis that the C shaft rotates by 90 degrees, controlling the C shaft to rotate by 90 degrees again, namely the C shaft rotates by 180 degrees in total, and then cutting a third first square frame 21 at a corresponding position on the surface of the horizontal plate member 2 by the cutter; on the basis of the 180 deg. rotation of the C-axis, the C-axis is controlled to rotate 90 deg. again, i.e. the C-axis rotates 270 deg. in total, and the fourth first frame 21 is cut by the cutter spindle at the corresponding position on the surface of the horizontal plate member 2.
It should be noted that the initial position of the C-axis only needs to ensure that no matter which position of the horizontal plate 2 the C-axis rotates to, there is enough position for the tool to cut the first boxes 21, and the first boxes 21 do not interfere with each other.
As shown in fig. 5 to 7, in some alternative implementations of the present embodiment, the number of the first boxes 21 may be four, and the step of calibrating the rotation radius of the C-axis by measuring and comparing the distance from the same side of each first box 21 to a side of the second box 22 located near the side of each first box 21 specifically includes:
in step S210, distances from the same side of each first frame 21 to a side of the second frame 22 located near the side of each first frame 21 are measured, which may be a, b, c, and d, respectively.
And step S220, comparing the values of a, b, c and d.
In step S230, if the values of a, b, C, and d are not equal and are outside the allowable deviation range, the C-axis turning radius deviation value needs to be calculated and added to the machining program to calibrate the turning radius of the C-axis.
Specifically, the calculated deviation value of the C-axis rotating radius is supplemented into a processing program, after the processing program obtains the deviation value of the C-axis rotating radius, the current C-axis rotating radius is interpolated according to the deviation value of the C-axis rotating radius, so that when the C-axis drives the cutter to rotate in the cutting process, the cutter processes the workpiece on a correct processing track through the compensation of the deviation value of the C-axis rotating radius on the original C-axis rotating radius.
And step S240, if the values of a, b, C and d are equal or the difference value is within the allowable deviation range, maintaining the current C-axis rotating radius calibration.

Referring to fig. 6 and 7, in particular, in an embodiment of the present invention, in order to better understand the calculation process of the C-axis turning radius deviation value, the following formula is used to explain the calculation process:
and calculating beta according to the values of a, b, c and d. The formula for calculating the deviation value of the rotating radius of the shaft C is as follows:
β＝|(a-b)+(c-d)|/2；
when a is more than b, beta is a positive value; conversely, when a < b, β is negative.
The value of beta obtained by the formula can be supplemented into a processing program so as to calibrate the rotating radius of the C shaft when the C shaft drives the cutter to rotate in the cutting process.

Specifically, the calculated A-axis zero offset value is supplemented into a machining program, and after the machining program obtains the A-axis zero offset value, the current A-axis zero position is supplemented according to the A-axis zero offset value, so that when the cutter is driven to rotate by the A-axis in cutting machining, the cutter is enabled to machine the workpiece on a correct machining track through the compensation of the A-axis zero offset value on the original A-axis zero position.
Step S340a, if the values of a 'and b' are equal and within the allowable deviation range, the current zero position of the a axis is maintained during the cutting process and the a axis drives the cutter to rotate.

from the values of a ', b', L1 and k, γ was determined. The formula for calculating the zero offset value of the A axis is as follows:
when a 'is less than L1 and b' is greater than L1,
a`＝L1-2Sinγ，b`＝L1+2Sinγ，
derived, Sin γ ═ (a '-b')/4 k;
when a 'is more than b', gamma is a positive value; conversely, when a 'is less than b', gamma is negative.
The value of gamma obtained by the formula can be supplemented into a processing program so as to carry out zero calibration on the shaft A when the shaft A drives the cutter to rotate in the cutting process.
Note that fig. 10 shows a state where the zero position of the a axis has an offset and is not calibrated; fig. 11 shows a state in which the zero position of the a axis is calibrated.

Specifically, the calculated C-axis zero offset value is supplemented into a machining program, and after the machining program obtains the C-axis zero offset value, the current C-axis zero position is supplemented according to the C-axis zero offset value, so that when the cutter is driven to rotate by the C-axis in cutting machining, the cutter is enabled to machine the workpiece on a correct machining track through the compensation of the C-axis zero offset value on the original C-axis zero position.
Step S340b, if the values of C 'and d' are equal and within the allowable deviation range, the current C-axis zero position is maintained during the cutting process and the C-axis drives the cutter to rotate.
Namely, in the next cutting process, when the C shaft drives the cutter to rotate, the current zero position of the C shaft is maintained.
As shown in fig. 9 to 11 and fig. 14 and 15, in some optional implementations of the present embodiment, the step of calculating the C-axis zero offset value specifically includes:
step S331b, obtaining the a-axis radius target value k, and obtaining a horizontal standard value L2, where the horizontal standard value L2 is a value that the third frame 31 and the fourth frame 32 should have when the distances c ', d' of the horizontally adjacent sides of the second erected panel 3 are equal.
And S332b, calculating a zero position deviation value delta of the C axis according to the values of C 'and d', k and L2.

from the values of c ', d', L2 and k, δ is determined. The formula for calculating the zero offset value of the C axis is as follows:
when c '< L2, d' > L2,
c`＝L1-2Sinδ，d`＝L1+2Sinδ，
derived, Sin δ ═ (c '-d') |/4 k;
when c 'is more than d', delta is a positive value; conversely, when c '< d', δ is negative.
