Description

Technical Field

[0001] This invention belongs to the field of rotary part processing technology, and particularly relates to a roughness detection method and system for rotary part processing based on 5G. Background Technology

[0002] 5G is a new generation of broadband mobile communication technology characterized by high speed, low latency, and massive connectivity. It serves as the network infrastructure for realizing the interconnection of humans, machines, and things.

[0003] Rotating parts are parts that can rotate around the center line of a certain component. They generally refer to shaft-type parts and disc-type parts, and the outer edge of the cross-section is circular.

[0004] In existing rotary part machining processes, the rotary part needs to be fixed on a lathe and rotated around its axial centerline before machining. When performing surface roughness inspection, the part must be removed from the lathe's machining spindle after machining is complete before the circumferential surface roughness can be inspected. If the surface roughness of the circumferential surface does not meet the finished product requirements, the part must be re-fixed on the lathe and re-machined, resulting in low work efficiency.

[0005] Therefore, there is an urgent need for a technical solution that can detect whether the surface roughness of the circumferential side of a rotating part meets the requirements of the finished product during the processing. Summary of the Invention

[0006] One of the objectives of this invention is to address the shortcomings of existing technologies by providing a roughness detection method for rotary parts based on 5G technology. This method solves the problem that existing technologies cannot detect whether the surface roughness of the circumferential side of the rotary part meets the requirements of the finished product during the machining process.

[0086] S100b: If the external dimensions of the rotating part do not meet the workpiece size requirements, a corresponding alarm will be issued.

[0087] S200: The first 5G laser sensor scans the rotating part at the machining shaft, and the second scan acquires the external dimensions of the rotating part and uploads them via 5G communication to generate a rough outline drawing of the rotating part; then, the finished outline drawing of the rotating part is acquired, and it is determined whether the rough outline drawing can encompass the finished outline drawing. The finished outline drawing of the rotating part is stored in the memory. The finished outline drawing can be generated from the pre-scanned finished part or it can be an electronic 3D drawing.

[0088] S200a, if the outline drawing of the rotary part blank can encompass the outline drawing of the rotary part finished product, the machine tool is scanned by the first 5G laser sensor to confirm the relative positions of the rotary part, the second 5G laser sensor, and the tool holder on the machine tool and the data is uploaded via 5G communication.

[0089] S200b: If the outline drawing of the rotating part blank cannot encompass the outline drawing of the finished rotating part, a corresponding alarm will be issued. Specifically, the alarm is implemented through a buzzer or an indicator light.

[0090] S300 establishes a coordinate system based on the relative positions of the rotating component, the second 5G laser sensor, and the tool holder on the machine tool.

[0091] More specifically, the origin of the coordinate system is the laser divergence point of the second 5G laser sensor, that is, the coordinates of the second 5G laser sensor are (0, 0).

[0092] A coordinate system is established based on the relative positions of the rotating component, the second 5G laser sensor, and the tool holder on the machine tool, which facilitates the subsequent acquisition of measurement point coordinates from the circumferential side of the rotating component.

[0093] S400, based on the coordinate system, scans the outer edge of the cross-section of the circumferential side of the rotating part using a second 5G laser sensor to obtain the coordinates of at least 4 circular measurement points and uploads them via 5G communication; that is, at least the coordinates of the circular measurement points S1(x1, y1), S2(x2, y2), S3(x3, y3) and S4(x4, y4) are obtained; more preferably, at least 5 to 13 circular measurement point coordinates are obtained and uploaded via 5G communication.

[0094] S500 calculates and analyzes the coordinates of the circular measurement point to determine whether the shape of the outer edge contour of the cross section conforms to a circle.

[0095] Specifically, including:

[0096] S510, take the coordinates of 3 circular measurement points to form a reference circle, and calculate the coordinates of the center of the reference circle and the radius of the reference circle.

[0097] That is, the coordinates of the circular measurement points S1(x1, y1), S2(x2, y2) and S3(x3, y3) are used to form a reference circle;

[0098] According to the equation of the perpendicular bisector of S1S2:

[0099] as well as

[0100] According to the equation of the perpendicular bisector of S2S3:

[0103] At the same time, according to the equation And y0 = Ax0 + C1;

[0104] Calculate the coordinates of the intersection point of the perpendicular bisector of S1S2 and the perpendicular bisector of S2S3, which is the coordinates of the center of the reference circle C0(x0, y0).

[0105] Furthermore, according to the equation

[0106] Calculate the radius of the reference circle, i.e., the value of r0;

[0107] S520, take the coordinates S of the remaining circular measurement points. n (x n y n () as the comparison coordinates;

[0112] Calculate the absolute value of the difference between the distance value and the radius of the reference circle, N. n The value;

[0113] S540, return to the execution of the step of taking one circular measurement point coordinate from the remaining circular measurement point coordinates as the comparison coordinate and calculating the distance value between the comparison coordinate and the center coordinate of the reference circle, until all remaining circular measurement point coordinates are used as comparison coordinates and the corresponding distance values ​​are calculated.

[0114] S560, determine whether the absolute values ​​of all differences are less than or equal to the allowable deviation value; where the allowable deviation value is 0.02 to 0.002 mm; select an appropriate value based on the actual situation;

[0115] S560a, if the absolute value of all differences is less than or equal to the allowable deviation value, then the shape of the outer edge profile of the cross section conforms to a circle;

[0116] S560b, if the absolute value of the difference is greater than the allowable deviation value, the shape of the outer edge profile of the cross section does not conform to the circle.

[0117] S500a, if the outer edge contour of the cross-section conforms to a circle, the machining spindle is started, and the machining spindle drives the rotating part to rotate around its spindle centerline.

[0118] S500b: If the outer edge contour of the cross-section does not conform to a circle, a corresponding alarm will be issued. Specifically, the alarm is a buzzer or an indicator light.

[0119] S600, based on a coordinate system, periodically scans the outer edge of the cross-section of the circumferential side of a rotating part in a rotating state using a second 5G laser sensor, acquires multiple roughness measurement point coordinate sets at different time points, and uploads them via 5G communication. The roughness measurement point coordinate set includes multiple roughness measurement point coordinates.

[0120] That is, based on the coordinate system, the second 5G laser sensor periodically scans the outer edge of the cross-section of the circumferential side of the rotating part, and obtains the roughness measurement point coordinate groups H1, H2, H3, and H4 at different time points, which are then uploaded via 5G communication. The scanning positions of the roughness measurement point coordinate groups H1, H2, H3, and H4 are all different; among them, the time points of the period include T1, T2, T3, and T4.

[0121] S700, based on the roughness measurement point coordinate group H1, H2, H3, H4, calculation and analysis are performed to obtain the actual surface average coefficient value of the rotating part along the X-axis and the actual surface average coefficient value along the Y-axis.

[0122] Specifically, including:

[0123] S710, select one roughness measurement point coordinate group, and filter out the largest X-axis coordinate value, the smallest X-axis coordinate value, the largest Y-axis coordinate value, and the smallest Y-axis coordinate value from multiple roughness measurement point coordinates;

[0125] S720, calculate the difference between the maximum X-axis coordinate value H1xmax and the minimum X-axis coordinate value H1xmin, and obtain the corresponding actual surface system value Δx1 on the X-axis; calculate the difference between the maximum Y-axis coordinate value H1ymax and the minimum Y-axis coordinate value H1ymin, and obtain the corresponding actual surface system value Δy1 on the Y-axis.

[0126] That is, H1xmax - H1xmin = Δx1; H1ymax - H1ymin = Δy1;

[0127] S730, return to the step of selecting one roughness measurement point coordinate group and filtering out the largest X-axis coordinate value, the smallest X-axis coordinate value, the largest Y-axis coordinate value and the smallest Y-axis coordinate value from multiple roughness measurement point coordinates, that is, return to the step of S710 until all roughness measurement point coordinate groups have obtained the corresponding X-axis actual surface system value and Y-axis actual surface system value.

[0128] That is, we get Δx2, Δx3, Δx4, Δy2, Δy3 and Δy4 accordingly;
