Description

Technical Field

[0001] The present invention relates to the technical field of lathes, and more specifically, to a method for determining the main plane of the main axis of a lathe by bisecting a turned part with a taper. Background Art

[0002] In the installation of the lathe spindle, the spindle must have a high degree of parallelism with the Z axis that moves parallel to the axis centerline, and a high degree of verticality with the X axis that moves perpendicular to the axis centerline. Only when the spatial accuracy of these two items is guaranteed can the spindle box be positioned, the screws locked, and even the positioning pins be installed. The way to check the accuracy is often to insert a gauge into the high-precision tapered hole machined at the front end of the spindle. Use a micrometer (verb indicator) and a rotating spindle to measure the spindle rotation runout. Use the moving Z axis and X axis to determine the secondary plane (the surface perpendicular to the tool movement) through changes. The secondary plane is mainly ensured by scraping the contact surface between the spindle box and the bed. Measure at the near and far ends of the gauge. Use the moving Z to determine the main plane (the tool movement surface) through changes. The main plane is fixed by swinging the spindle box when the data is minimum. This is the conventional way to determine the installation of the lathe spindle. The advantage of this method is that it is simple and feasible. As long as the accuracy of the spindle taper hole processing is high enough and the accuracy of the inspection fixture is high enough, the spatial position of the spindle can be determined by inserting the inspection fixture in the above way.

[0003] Another existing method is to use the self-machined part as a checking fixture. Before the main plane of the spindle axis is determined, the self-machined part is regarded as a theoretical cone, and the lathe tool is used to move on the cone generatrix. The size of the taper is known by using a micrometer to detect the data change of the opposite position of the tool, and then the lathe spindle is swung, and the jump of the micrometer is detected to divide the original taper into two. The final position is the position of the spindle axis to be determined on the main plane. This method is time-consuming and labor-intensive to operate, and cannot quickly determine the position of the main plane of the lathe spindle axis, and has certain limitations.

[0004] In order to solve the above problems, a technical solution is now provided. Summary of the invention

[0012] In a preferred embodiment, the thresholds of the force interval are set, marked as Sup and Sdown respectively; If Sup ≤ first force interval S1 ≤ Sdown, a normal signal is output; if the first force interval S1 Sdown, an early warning is issued for the first force interval S1; If Sup ≤ second force interval S2 ≤ Sdown, a normal signal is output; if the second force interval S2 Sdown, an early warning is issued for the second force interval S2; If Sup ≤ the third stress interval S3 ≤ Sdown, a normal signal is output; if the third stress interval S3 Sdown, an early warning is issued for the third stress interval S3; If Sup≤fourth stress interval S4≤Sdown, a normal signal is output; if the fourth stress interval S4Sdown, an early warning is issued for the fourth stress interval S4.

[0013] It should be noted that, in this way, the main plane of the lathe spindle axis can be determined.

[0014] In a preferred embodiment, when a normal signal is output, it indicates that the position of the force interval corresponding to the main plane of the lathe spindle axis is normal; When the warning is issued in the first force interval S1, it indicates that there is an abnormality in the position of the first force interval S1 corresponding to the main plane of the lathe spindle axis; When the warning is issued in the second force interval S2, it indicates that there is an abnormality in the position of the second force interval S2 corresponding to the main plane of the lathe spindle axis; When the warning is issued in the third force interval S3, it indicates that there is an abnormality in the position of the third force interval S3 corresponding to the main plane of the lathe spindle axis; When the warning is issued in the fourth force-bearing interval S4, it indicates that there is an abnormality in the position of the fourth force-bearing interval S4 corresponding to the main plane of the lathe spindle axis.

[0015] It should be noted that in this way, the abnormal position of the main plane of the lathe spindle axis can be automatically monitored and processed.
