[0004] To address the aforementioned problems, this application provides a centering method applied to machining split-type parts on a vertical lathe. The vertical lathe includes a machine platform, the split-type part is disposed on the machine platform, and the machine platform is used to drive the split-type part to rotate. The split-type part includes a first body and a second body, with a split surface formed between the first body and the second body. The centering method includes:

[0009] Starting from the first point, drive the split-type part to rotate at the same height and on the same reference plane along both sides of the first point in the Z-axis direction of the equipment platform to obtain the second point and the third point;
[0010] Adjust the position of the first point so that the coordinate values of the second point and the third point are the same in the coordinate system.
[0011] Optionally, before establishing a coordinate system with the rotation center of the equipment platform as the origin, the centering method further includes:

[0014] Optionally, the first reference plane and the second reference plane are arranged parallel to the open face, and the first reference plane and the second reference plane are at the same distance from the open face.
[0015] Optionally, the length of the first reference plane and the second reference plane is greater than 50 mm, and the width of the first reference plane and the second reference plane is greater than 20 mm.
[0016] Optionally, adjusting the position of the first point includes:

[0028] Beneficial effects
[0029] The centering method provided in the embodiments of the present invention first rotates the equipment platform to drive the split part to rotate, and then aligns the third reference plane so that the third reference plane is parallel to the equipment platform, that is, the split surface of the split part is perpendicular to the equipment platform, ensuring that the rotation center line of the split part is on the split surface. Then, a first point is selected on the first reference plane, and the split-type part is driven to rotate by the same angle in different directions from the first point to obtain the second and third points. By adjusting the position of the first point and comparing the coordinate values of the second and third points on a coordinate system established with the rotation center of the equipment platform as the origin, the positional relationship between the split-type part and the rotation center of the equipment platform can be determined. This allows for quick alignment of the rotation center of the equipment platform and the centerline of the split-type part when they are misaligned in only one direction. Compared to conventional alignment operations, this method is more efficient and improves the user experience. Simultaneously, using the position of the first point as a reference, the equipment platform is driven to rotate 180°, and a fourth point is selected on the second reference plane of the split-type part. Then, using the fourth point as a starting point, the split-type part is driven to rotate in different directions. By moving the same angle to obtain points five and six, and comparing the coordinate values of points five and six on a coordinate system established with the rotation center of the equipment platform as the origin, the positional relationship between the split-type part and the equipment platform can be determined. This verifies the alignment between the center of the split-type part and the rotation center of the equipment platform, improving alignment accuracy and thus improving the machining quality of the split-type part. Simultaneously, by comparing the coordinate values of points one and four on a coordinate system established with the rotation center of the equipment platform as the origin, the positional relationship between the split-type part and the rotation center of the equipment platform can be determined. This operation allows for rapid alignment of the rotation center of the equipment platform and the center line of the split-type part when they are misaligned in two directions. Compared to conventional alignment operations, this method is more efficient and further improves the user experience. Attached Figure Description

[0042] See also Figures 1 to 6As shown, according to an embodiment of this application, a centering method is provided for machining a split-type part 2 on a vertical lathe. The vertical lathe includes a machine platform 1, and the split-type part 2 is disposed on the machine platform 1. The machine platform 1 is used to drive the split-type part 2 to rotate. The split-type part 2 includes a first body 21 and a second body 22, and a split surface is formed between the first body 21 and the second body 22.
[0043] Among them, the vertical lathe is a type of lathe with its spindle axis perpendicular to the horizontal plane and the workpiece mounted on a horizontal rotary worktable. It is used to process large and heavy workpieces with large radial dimensions and relatively small axial dimensions and complex shapes.
[0044] In this embodiment of the application, the part to be processed is a split part 2.
[0045] Among them, the open-type part 2 can be a circular ring.
[0046] Among them, equipment platform 1 is the rotary table of a vertical lathe.
[0047] Specifically, the split-type part 2 is placed on the equipment platform 1, which has grippers that can clamp the split-type part 2. During machining, the vertical lathe can drive the equipment platform 1 to rotate, thereby causing the split-type part 2 on it to rotate, thus realizing the machining of the split-type part 2.
[0048] The split-type part 2 comprises two parts: the first part is the first body 21, and the second part is the second body 22. The first body 21 and the second body 22 are roughly semi-circular.
[0049] Specifically, the first body 21 and the second body 22 are arranged opposite to each other, and a center-open face is formed between the first body 21 and the second body 22.
[0050] Among them, the open surface is perpendicular to the equipment platform 1, and the center line of the open part 2 is on the open surface.
[0051] The present invention aims to propose an alignment method that can ensure that the centerline of the split part 2 coincides with the rotation center of the equipment platform 1 during processing, so as to improve the processing accuracy of the split part 2.
[0052] The methods for mediating include:
[0053] Step S1: Using the center face as the clamping reference, machine the first reference surface 211 and the third reference surface A23 on the first body 21.
[0054] The split-type part 2 is clamped with the split surface as the reference, and then the first reference surface 211 and the third reference surface A23 can be machined by milling or grinding. The first reference surface 211 is a plane and is parallel to the split surface of the split-type part 2. The third reference surface A23 is perpendicular to the split surface of the split-type part 2.
[0055] Specifically, the first reference surface 211 is parallel to the open surface of the open part 2, and the first reference surface 211 is located on the side of the first body 21 away from the second body 22.
[0056] In some possible embodiments, a groove is provided on the side of the first body 21 away from the second body 22, and the first reference surface 211 is the bottom surface of the groove.
[0057] Step S2: Together with the first body 21, the second reference surface 221 and the third reference surface B24 are machined on the second body 22 using the center face as the clamping reference.
[0058] The split-type part 2 is clamped with the split surface as the reference, and then the second reference surface 221 and the third reference surface B24 can be machined by milling or grinding. The second reference surface 221 is a plane and is parallel to the split surface of the split-type part 2. The third reference surface B24 is perpendicular to the split surface of the split-type part 2.
[0059] Specifically, the second reference surface 221 is parallel to the open surface of the open part 2, and the second reference surface 221 is located on the side of the second body 22 away from the first body 21.
[0060] In some possible embodiments, the second body 22 has a groove on the side away from the first body 21, and the second reference surface 221 is the bottom surface of the groove.
[0061] Step S3: Drive the device platform 1 to rotate so that the third reference plane 23 is parallel to the device platform 1.
[0062] Specifically, the rotating equipment platform 1 drives the split-type part 2 to rotate, so that the third reference plane A23 and the third reference plane B24 are parallel to the equipment platform 1, thereby ensuring that the split-type part's split surface is perpendicular to the equipment platform 1.
[0063] Step S4: Establish a coordinate system with the rotation center of equipment platform 1 as the origin.
[0064] Among them, equipment platform 1 is the rotary table of the vertical lathe, and equipment platform 1 is set horizontally.
[0065] Specifically, the equipment platform 1 is used to support the split-type part 2. The centerline of the split-type part 2 is perpendicular to the equipment platform 1. By adjusting the position of the split-type part 2 so that the centerline of the split-type part 2 coincides with the rotation center of the equipment platform 1, the centering operation between the split-type part 2 and the equipment platform 1 can be completed.
[0066] A coordinate system can be established with the rotation center of equipment platform 1 as the origin to determine the positional relationship between the split part 2 and the rotation center of equipment platform 1.
[0067] Specifically, the rotation center of the equipment platform 1 is the origin of the coordinate system, i.e., point O. The coordinate system has an X-axis, a Y-axis, and a Z-axis. The X-axis and Y-axis are perpendicular to each other on the equipment platform 1, and the Z-axis is perpendicular to the X-axis and Y-axis through point O (which is also the rotation center line of the equipment platform 1). The X-axis, Y-axis, and Z-axis each have coordinate values used to display the coordinate information of the split-type part 2. In this embodiment, the split-type part 2 has a regular shape, and its center line can be determined. By adjusting the position of the split-type part 2 so that its center line coincides with the Z-axis, the alignment operation between the split-type part 2 and the equipment platform 1 can be completed.
[0068] Step S5: Select the first point 3 on the first reference plane 211.
[0069] Among them, point 3 should be the midpoint on the first reference plane 21.
[0070] Step S6: Starting from the first point 3, drive the split-type part 2 to rotate at the same height and on the same reference plane in the Z-axis direction of the equipment platform 1 along both sides of the first point by the same angle to obtain the second point 4 and the third point 5.
[0071] Among them, point 3 is the reference point.
[0072] The vertical lathe can drive the equipment platform 1 to rotate via the spindle, and the equipment platform 1 can drive the split-type part 2 to rotate in different directions to obtain the second point 4 and the third point 5.
[0073] For details, see Figure 3-6As shown, points 4 and 5 are detection points. The position of the first point can be determined by comparing the coordinate values of points 4 and 5. In this embodiment, the device platform 1 drives the split-type part 2 to rotate counterclockwise by an angle α to obtain point 4. At this time, the angle between the line connecting point 4 and the origin O of the coordinate system and the line connecting point 3 and the origin O of the coordinate system is α. The device platform 1 drives the split-type part 2 to rotate clockwise by an angle α to obtain point 5. At this time, the angle between the line connecting point 5 and the origin O of the coordinate system and the line connecting point 3 and the origin O of the coordinate system is α. It can be understood that the position of point 4 is the position of point 3 in the coordinate system when point 3 rotates counterclockwise by an angle α; the position of point 5 is the position of point 3 in the coordinate system when point 3 rotates clockwise by an angle α.
[0074] Among them, the distances from the line connecting the first point 3, the second point 4, and the third point 5 to the equipment platform 1 are equal.
[0075] Specifically, points 3, 4, and 5 are all located on the first reference plane 211, and the distance between points 2 and 3 is as far as possible (to improve alignment accuracy). The line connecting point 1 to the origin O of the coordinate system is the bisector of the angle formed by the lines connecting points 4 and 5 to the origin O of the coordinate system.
[0076] Step S7: Adjust the position of the first point 3 so that the coordinate values of the second point 4 and the third point 5 are the same in the coordinate system.
[0077] Specifically, comparing the coordinate values of the second point 4 and the third point 5, if they are the same, it indicates that the first point 3 is located on the X-axis or Y-axis of the coordinate system. It can be understood that the second point 4 and the third point 5 are obtained by rotating the split-type part 2; that is, the fact that the coordinate values of the second point 4 and the third point 5 are the same also indicates that the centerline of the split-type part 2 is located on the X-axis or Y-axis of the coordinate system. Therefore, when the equipment platform 1 and the split-type part 2 are misaligned in only one direction, the above method can be used to achieve the alignment operation between the equipment platform 1 and the split-type part 2.
[0078] The technical solution provided in the embodiments of the present invention selects a first point 3 on the split part 2 and drives the split part 2 to rotate by the same angle in different directions from the first point 3 as the starting point to obtain a second point 4 and a third point 5. By adjusting the position of the first point 3 and comparing the coordinate values of the second point 4 and the third point 5 on the coordinate system established with the rotation center of the equipment platform 1 as the origin, the positional relationship between the split part 2 and the equipment platform 1 can be determined. This method can quickly complete the alignment operation between the rotation center of the equipment platform 1 and the split part 2 when the rotation center of the equipment platform 1 and the split part 2 are misaligned in only one direction. Compared with conventional alignment operations, this method has higher work efficiency and improves the user experience.
[0079] In practical applications, adjusting the position of point 3 includes:
[0080] Adjust the position of the first point 3 on the first reference plane 211 and / or adjust the position of the open part 2 on the coordinate system.
[0081] It can be understood that if the coordinate values of the second point 4 and the third point 5 are the same, then the first point 3 is the highest point on the first body 21 of the split part 2. The perpendicular line from the first point 3 to the split surface of the split part 2 is the bisector of the first body 21, with the foot of the perpendicular on the split surface. The first point 3 is located on the X-axis or Y-axis of the coordinate system, and the bisector of the first body 21 coincides with the X-axis or Y-axis of the coordinate system.
[0082] Specifically, first select a point 3 at the middle position on the first reference plane 211. Rotate the equipment platform 1 to obtain the second point 4 and the third point 5 on the first reference plane 211. Compare the coordinate values of the second point 4 and the third point 5. If they are different, adjust the position of the split part 2 on the coordinate system until the coordinate values of the second point 4 and the third point 5 on the coordinate system are the same.
[0083] The adjustment of the position of the first point 3 on the first reference plane 211 is achieved by adjusting the position of the split part 2 in the coordinate system.
[0084] In the above embodiments, the centering method further includes:
[0085] Step S8: Using the position of the first point 3 as a reference, drive the device platform 1 to rotate 180° and obtain the fourth point 6 on the second reference plane 221.
[0086] Specifically, the line connecting point 6 (fourth point) and point 3 (first point) is perpendicular to the open surface and is a bisector of the open part 2. The centerline of the open part 2 lies on this line and coincides with the X-axis or Y-axis of the coordinate system.
[0087] In the above embodiments, the centering method further includes:
[0088] Step S9: Starting from point 6, drive the split part 2 to rotate at the same height and on the same reference plane along both sides of point 6 in the Z-axis direction of the equipment platform 1 to obtain point 7 and point 8.
[0089] Among them, point 6 is the reference point.
[0090] The vertical lathe can drive the equipment platform 1 to rotate via the spindle, and the equipment platform 1 can drive the split-type part 2 to rotate in different directions to obtain the fifth point 7 and the sixth point 8.
[0091] For details, see Figure 3-6As shown, points 7 and 8 are detection points. By comparing the coordinate values of points 7 and 8, the position of point 6 can be determined. In this embodiment, the device platform 1 drives the split-type part 2 to rotate counterclockwise by an angle α to obtain point 7. At this time, the angle between the line connecting point 7 and the origin O of the coordinate system and the line connecting point 6 and the origin O of the coordinate system is α. The device platform 1 drives the split-type part 2 to rotate clockwise by an angle α to obtain point 8. At this time, the angle between the line connecting point 8 and the origin O of the coordinate system and the line connecting point 6 and the origin O of the coordinate system is α. It can be understood that the position of point 7 is the position of point 6 in the coordinate system when point 6 rotates counterclockwise by an angle α; the position of point 8 is the position of point 6 in the coordinate system when point 6 rotates clockwise by an angle α.
[0092] Among them, the distances between the lines connecting points 4.6, 5.7, and 6.8 and the equipment platform 1 are equal.
[0093] Specifically, points 6, 7, and 8 can all be located on the second datum plane 221, with points 7 and 8 as far apart as possible (to improve alignment accuracy). The line connecting point 6 to the origin of the coordinate system is the bisector of the angle formed by the lines connecting points 7 and 8 to the origin of the coordinate system.
[0094] Step S10: Compare the coordinate values of point 7 (the fifth point) and point 8 (the sixth point) in the coordinate system.
[0095] Specifically, comparing the coordinate values of point 7 (fifth point) and point 8 (sixth point), if they are the same, it indicates that point 6 (fourth point) is located on the X-axis or Y-axis of the coordinate system. It can be understood that points 7 (fifth point) and 8 (sixth point) are obtained by rotating the split-type part 2; that is, if the coordinate values of points 7 (fifth point) and 8 (sixth point) are the same, it also indicates that the centerline of the split-type part 2 is located on the X-axis or Y-axis of the coordinate system. Therefore, when the equipment platform 1 and the split-type part 2 are misaligned in only one direction, the above method can be used to achieve the alignment operation between the equipment platform 1 and the split-type part 2.
[0096] The technical solution provided in the embodiments of the present invention, by using the position of the first point 3 as a reference, drives the equipment platform 1 to rotate 180° and selects the fourth point 6 on the split part 2. Then, starting from the fourth point 6, drives the split part 2 to rotate by the same angle in different directions to obtain the fifth point 7 and the sixth point 8. By comparing the coordinate values of the fifth point 7 and the sixth point 8 on the coordinate system established with the rotation center of the equipment platform 1 as the origin, the positional relationship between the split part 2 and the equipment platform 1 can be determined. This verifies the alignment of the split part 2 and the equipment platform 1, improves the alignment accuracy, and thus improves the processing quality of the split part 2.
[0097] It can be understood that if the coordinate values of the fifth point 7 and the sixth point 8 are the same, then the fourth point 6 is the highest point of the second body 22 of the split part 2. The perpendicular line from the fourth point 6 to the split surface of the split part 2 is the bisector of the second body 22, with the foot of the perpendicular on the split surface. The fourth point 6 is located on the X-axis or Y-axis of the coordinate system, and the bisector of the second body 22 coincides with the X-axis or Y-axis of the coordinate system.
[0098] Specifically, first compare the coordinate values of point 7 (fifth point) and point 8 (sixth point). If they are different, the first datum plane 211, the second datum plane 221, the third datum plane A23, and the third datum plane B24 need to be re-machined, and then the alignment is repeated according to S1-S12. For example, first select a point 3 at the middle position on the first datum plane 221. Rotate the equipment platform 1 to obtain the second point 4 and the third point 5 on the first datum plane 211. Compare the coordinate values of the second point 4 and the third point 5. If they are different, adjust the position of the split part 2 on the coordinate system until the coordinate values of the second point 4 and the third point 5 are the same.
[0099] Understandably, the position of point 6 is usually determined in one step. Points 7 and 8 are used to verify whether point 6 is correct. Because the first reference plane 21 is parallel to the second reference plane 22, and both are parallel to the split surface; point 3 completes the alignment, and the split part 2 rotates 180° to obtain point 6. If the equipment accuracy is good, the coordinate values of point 7 and point 8 will definitely be the same.
[0100] In the above embodiments, the centering method further includes:
[0101] Step S11: Adjust the position of the split part 2 on the equipment platform 1 so that the coordinate values of the first point 3 and the fourth point 6 are the same in the coordinate system.
[0102] Among them, when the coordinate values of the second point 4 and the third point 5 are the same, and the coordinate values of the fifth point 7 and the sixth point 8 are the same, the line connecting the first point 3 and the fourth point 6 can coincide with the X-axis or Y-axis of the coordinate system.
[0103] Specifically, taking the example where the line connecting the first point 3 and the fourth point 6 coincides with the Y-axis of the coordinate system, the centerline of the split part 2 is located on the Y-axis of the coordinate system, but not necessarily on the X-axis. It can be understood that when the centerline of the split part 2 is simultaneously located on both the X-axis and Y-axis of the coordinate system, the center of the split part 2 coincides with the Z-axis of the rotation center of the equipment platform 1. The alignment method in this application also includes adjusting the position of the split part 2 on the equipment platform 1 so that the coordinate values of the first point 3 and the fourth point 6 are the same in the coordinate system.
[0104] When the coordinates of the first point 3 and the fourth point 6 are in the coordinate system, the midpoint of the line connecting the first point 3 and the fourth point 6 coincides with the Z-axis of the coordinate system. At this time, the centering operation between the split part 2 and the equipment platform 1 is completed.
[0105] The technical solution provided in the embodiments of the present invention can determine the positional relationship between the split part 2 and the equipment platform 1 by comparing the coordinate values of the first point 3 and the fourth point 6 on the coordinate system established with the rotation center of the equipment platform 1 as the origin. When the equipment platform 1 and the split part 2 are misaligned in two directions, the centering method can quickly complete the centering operation between the equipment platform 1 and the split part 2. Compared with manual centering, the work efficiency is higher and the user experience is improved.
[0106] In the above embodiment, the first reference surface 211 and the second reference surface 221 are arranged in parallel, and the first reference surface 211 and the second reference surface 221 are at the same distance from the open surface of the open part 2.
[0107] By setting the first reference plane 211 and the second reference plane 221 to be at the same distance from the open surface of the split part 2, the centering efficiency and accuracy of the split part 2 and the equipment platform 1 can be improved, thereby improving the machining accuracy of the split part 2.
[0108] In the above embodiment, the length of the first reference surface 211 and the second reference surface 221 is greater than 50 mm, and the width of the first reference surface 211 and the second reference surface 221 is greater than 20 mm.
[0109] Among them, the length of the first reference surface 211 and the second reference surface 221 is greater than 50mm, which can increase the distance between the detection point and the reference point, making it easier for the operator to judge the position of the detection point, and making the reading of the detection point on the coordinate system more accurate, thereby improving the alignment accuracy between the split part 2 and the equipment platform 1.
[0110] Specifically, in this embodiment of the application, the width of the first reference surface 211 and the second reference surface 221 is greater than 20mm.
[0111] The alignment method provided in the embodiments of the present invention first rotates the equipment platform 1 to drive the split-type part 2 to rotate, aligning it with the third reference plane 23 so that the split-type surface of the split-type part 2 is perpendicular to the equipment platform 1, ensuring that the centerline of the split-type part 2 is on the split-type surface. Then, a first point 3 is selected on the first reference plane 211, and the split-type part 2 is driven to rotate in different directions by the same angle from the first point 3 to obtain the second point 4 and the third point 5. By adjusting the position of the first point 3 and comparing the coordinate values of the second point 4 and the third point 5 on the coordinate system established with the rotation center of the equipment platform 1 as the origin, the positional relationship between the split-type part 2 and the rotation center of the equipment platform 1 can be determined. This method can quickly complete the alignment operation between the rotation center of the equipment platform 1 and the split-type part 2 when the rotation center of the equipment platform 1 and the split-type part 2 are misaligned in only one direction. Compared with conventional alignment operations, it has higher work efficiency and improves the user experience. At the same time, using the position of the first point 3 as a reference, the equipment platform 1 is rotated to drive the split-type part 2 to rotate. The platform 1 is rotated 180° and a fourth point 6 is selected on the split part 2. Then, starting from the fourth point 6, the split part 2 is driven to rotate by the same angle in different directions to obtain a fifth point 7 and a sixth point 8. By comparing the coordinate values of the fifth point 7 and the sixth point 8 on the coordinate system established with the rotation center of the equipment platform 1 as the origin, the positional relationship between the split part 2 and the equipment platform 1 can be determined. This verifies the alignment between the split part 2 and the rotation center of the equipment platform 1, improves the alignment accuracy, and thus improves the processing quality of the split part 2. At the same time, by comparing the coordinate values of the first point 3 and the fourth point 6 on the coordinate system established with the rotation center of the equipment platform 1 as the origin, the positional relationship between the split part 2 and the equipment platform 1 can be determined. This method can quickly complete the alignment operation between the rotation center of the equipment platform 1 and the split part 2 when they are misaligned in two directions. Compared with conventional alignment operations, this method is more efficient and further improves the user experience.
