[0070] Embodiment 1

[0071] As shown in Figs. Figure 1 , 5 and 6;

[0072] S100, scanning the rotary piece in the part placement area in the workshop by the first 5G laser sensor, confirming the workshop placement position of the rotary piece and uploading it through 5G communication; scanning the rotary piece by the first 5G laser sensor, preliminarily acquiring the outer dimensions of the rotary piece and uploading it through 5G communication, and judging whether the outer dimensions of the rotary piece meet the workpiece size requirements.

[0073] S100a, if the outer dimensions of the rotary piece meet the workpiece size requirements, then according to the workshop placement position of the rotary piece, the rotary piece is fixed at the machining rotary shaft of the machine tool through the aisle of the workshop, and the rotary shaft center line of the rotary piece corresponds to the rotary shaft center line of the machining rotary shaft.

[0074] S100b, if the outer dimensions of the rotary piece do not meet the workpiece size requirements, then a corresponding alarm is issued. Specifically, the alarm is realized by a buzzer or a warning light.

The rotary piece finished product contour map is stored in the memory, and the rotary piece finished product contour map can be generated by pre-scanning the rotary piece finished product, or it can be an electronic three-dimensional drawing.

[0076] S200a, if the profile of the rotating part blank can include the profile of the rotating part finished product, then the first 5G laser sensor is used to scan the machine tool, the relative positions of the rotating part, the second 5G laser sensor and the tool holder on the machine tool are confirmed and uploaded through 5G communication.

[0077] S200b, if the profile of the rotating part blank cannot include the profile of the rotating part finished product, then a corresponding alarm is issued. Specifically, the alarm is realized by a buzzer or a prompt light.

[0078] S300, according to the relative positions of the rotating part, the second 5G laser sensor and the tool holder on the machine tool, a coordinate system is established.

[0079] More specifically, the laser divergence point of the second 5G laser sensor is taken as the coordinate origin, i.e. the second 5G laser sensor coordinate is (0, 0).

[0080] Wherein, the coordinate system is established based on the relative positions of the rotating part, the second 5G laser sensor and the tool holder on the machine tool, which is convenient for subsequent acquisition of measurement point coordinates from the circumferential side surface of the rotating part.

[0081] S400, based on the coordinate system, the cross-sectional outer edge of the circumferential side surface of the rotating part is scanned by the second 5G laser sensor, at least 4 measurement point coordinates are acquired and uploaded through 5G communication; that is, at least measurement point coordinates S1(x1, y1), S2(x2, y2), S3(x3, y3) and S4(x4, y4) are acquired; more preferably, at least 5 to 13 measurement point coordinates are acquired and uploaded through 5G communication.

[0082] S500, according to the measurement point coordinates, calculation and analysis are performed to determine whether the shape of the cross-sectional outer edge profile conforms to a circle;

[0083] Specifically, it includes:

[0084] S510, taking 3 measurement point coordinates to form a reference circle, the center coordinates of the reference circle and the radius value of the reference circle are calculated;

[0085] That is, taking measurement point coordinates S1(x1, y1), S2(x2, y2) and S3(x3, y3) to form a reference circle;

[0086] According to the median line equation of S1S2:

[0087] And

[0088] According to the median line equation of S2S3:

[0089]

[0090] Let

[0091] At the same time, according to the equation and y0 = Ax0 + C1;

[0092] The intersection coordinates of the midline of S1S2 and the midline of S2S3 are calculated, that is, the coordinates of the center of the reference circle C0(x0, y0);

[0093] Further, according to the equation

[0094] The radius value of the reference circle, that is, the value of r0, is calculated;

[0095] S520, taking the measurement point coordinates S n (x n , y n ) from the remaining measurement point coordinates as the comparison coordinates;

[0096] According to the equation

[0097] The distance value between the comparison coordinates and the center coordinates of the reference circle, that is, the value of r n , is calculated;

[0098] S530, calculating the absolute value of the difference between the distance value and the reference circle radius value;

[0099] That is, according to the formula N n = |r0-r n |;

[0100] The absolute value of the difference between the distance value and the reference circle radius value, N n , is calculated;

[0101] S540, returning to execute the step of taking one measurement point coordinate from the remaining measurement point coordinates as the comparison coordinates and calculating the distance value between the comparison coordinates and the center coordinates of the reference circle, that is, returning to the step of S520, until all the remaining measurement point coordinates are taken as the comparison coordinates and the corresponding distance values are calculated;

[0102] S560, judging whether all the absolute values of the differences are less than or equal to the deviation allowed value; wherein the deviation allowed value is 0.02 to 0.002 mm; according to the actual situation, a suitable value is selected;

[0103] S560a, if all the absolute values of the differences are less than or equal to the deviation allowed value, the shape of the cross-sectional outer edge profile conforms to a circle;

[0104] S560b, if there is an absolute value of the difference greater than the deviation allowed value, the shape of the cross-sectional outer edge profile does not conform to a circle.

[0105] S500a, if the shape of the cross-sectional outer edge profile conforms to a circle, output the shape detection result as a circle.

[0106] S500b, if the shape of the cross-sectional outer edge profile does not conform to a circle, output the shape detection result as a non-circle.

[0107] S600, according to the shape detection result, determine whether the perpendicular relationship between the tool tip direction and the rotation axis center line of the rotary part is perpendicular.

[0108] S600a, if the shape detection result is a circle, the perpendicular relationship between the tool tip direction and the rotation axis center line of the rotary part is perpendicular, and the output of the perpendicular relationship result is perpendicular.

[0109] Wherein, the shape detection result is a circle, which means that the second 5G laser sensor and the circumferential side of the rotary part are in a perpendicular relationship, that is, the second 5G laser sensor forms a standard circular arc shape at the measurement point profile of the circumferential side of the rotary part; Therefore, the perpendicular relationship between the tool tip direction and the rotation axis center line of the rotary part is perpendicular at this time; In the subsequent process, the position of the tool holder does not need to be adjusted.

[0110] S600b, if the shape detection result is a non-circle, the perpendicular relationship between the tool tip direction and the rotation axis center line of the rotary part is not perpendicular, and the output of the perpendicular relationship result is not perpendicular.

[0111] Wherein, the shape detection result is a non-circle, which means that the second 5G laser sensor and the circumferential side of the rotary part are not in a perpendicular relationship, that is, the second 5G laser sensor forms an elliptical or other shape at the measurement point profile of the circumferential side of the rotary part; Therefore, the perpendicular relationship between the tool tip direction and the rotation axis center line of the rotary part is not perpendicular at this time, that is, the tool tip direction is inclined; In the subsequent process, the position of the tool holder needs to be adjusted until the perpendicular relationship between the tool tip direction and the rotation axis center line of the rotary part is perpendicular.

[0112] Wherein, the machine tool is provided with a tool holder and a machining shaft, the tool holder is provided with a tool and a second 5G laser sensor, the second 5G laser sensor is located on one side of the tool, the scanning area of the second 5G laser sensor corresponds to the tool tip position of the tool, the rotary part is fixed at the machining shaft of the machine tool, and the rotation axis center line of the rotary part corresponds to the rotation axis center line of the machining shaft.

[0136] Due to the limitations of instruments, experimental conditions, environment and other factors, measurement cannot be infinitely accurate, and there will always be a certain difference between the measured value of a physical quantity and the true value that objectively exists.
