Description

Technical Field

[0001] This invention relates to the field of parts processing technology, and in particular to a processing method and processing system. Background Technology

[0002] In machining operations, machine tools are typically used to process workpieces to meet the processing requirements of various mechanical parts. However, when machining workpieces, machine tools are often affected by various interfering factors, leading to a large number of errors, such as: errors in the machine tool spindle, and improper application of grinding methods. In addition, using conventional methods to clamp workpieces onto the clamping devices connected to the machine tool spindle usually results in each machined workpiece having different error locations and amounts, making it impossible to achieve a uniform processing standard and thus preventing the mass production of workpieces of the same standard. Summary of the Invention

[0003] In view of the above, it is necessary to propose a processing method and processing system to reduce processing errors and achieve batch processing of workpieces with the same standard.

The first clamping member is detachably connected to the spindle and is used to clamp a predetermined part of a workpiece. The spindle drives the first clamping member to rotate. The grinding member is adjacent to the first clamping member and is used to grind the outer contour of the workpiece end. The processing method includes:

[0083] To better understand the objectives, features, and advantages of this invention, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of the invention and the features within them can be combined with each other. Numerous specific details are set forth in the following description to provide a thorough understanding of the invention; the described embodiments are only a part of, and not all, of the embodiments of the invention.

[0084] Please see Figure 1A , Figure 1B , Figure 2 and Figure 3 This application provides a processing method applied to a processing machine 100, so that the processing machine 100 can operate on a workpiece 200 (e.g., ...). Figure 4The processing is performed on the workpiece 200 (as shown) to reduce processing errors and achieve batch production of workpieces 200 according to the same standard. For the processing machine 100 requiring processing, the processing functions provided by the processing method of this application can be directly integrated onto the processing machine 100, or a client application for implementing the processing method of this application can be installed. Alternatively, the processing method provided by this application can also run on the processing machine 100 in the form of a software development kit (SDK), providing an interface for processing functions in the form of an SDK, through which processors or other devices can implement the processing functions.

[0085] Please see Figure 2 In some embodiments, the processing machine 100 includes a forming part 10 and a heating part 20. The forming part 10 and the heating part 20 are arranged at intervals. The forming part 10 is used to form the workpiece 200, and the heating part 20 is used to heat treat the workpiece 200. In this embodiment, the forming part 10 can be any forming part, forming block, or similar forming body capable of forming the workpiece 200. The heating part 20 includes a carburizing furnace and a tempering furnace, which sequentially heat treat the workpiece 200.

[0086] Please refer to 1A. The processing method of this application embodiment includes the following steps S10-S60.

[0087] Step S10: Obtain the preset dimension information of workpiece 200, which includes the dimension information of end 201 and the dimension information of inner hole 203.

[0088] Specifically, in order to accurately form the workpiece 200, it is necessary to obtain the preset size information of the workpiece 200 in advance. The preset size information of the workpiece 200 includes the size information of the end 201 and the size information of the inner hole 203. The preset size information of the workpiece 200 can be obtained through the design drawings.

[0089] Step S20: Based on the preset size information of workpiece 200, control the forming part 10 to form workpiece 200, and determine that workpiece 200 retains a first preset allowance.

[0090] Specifically, by controlling the forming part 10 to form the workpiece 200 based on the preset size information of the workpiece 200, the workpiece 200 is rough-machined, and a first preset allowance is determined for the workpiece 200 to be retained, which facilitates the forming part 10 to form multiple workpieces 200 in batches, thereby improving the forming efficiency of the workpiece 200. In this embodiment of the application, the first preset allowance is 0.3mm.

[0091] Step S30: Obtain workpiece 200 forming information, which includes workpiece 200 being formed and workpiece 200 not being formed.

[0092] Specifically, the forming information of workpiece 200 includes "workpiece 200 is formed" and "workpiece 200 is not formed". "Workpiece 200 is formed" indicates that workpiece 200 has been formed and rough-machined by forming part 10, and "workpiece 200 is not formed" indicates that workpiece 200 has not been formed and rough-machined by forming part 10. By obtaining the forming information of workpiece 200, it is convenient for heating part 20 to perform heat treatment on the formed workpiece 200.

[0093] Step S40: Based on the forming information of workpiece 200, the workpiece 200 is formed, and the heating element 20 is controlled to heat treat the formed workpiece 200.

[0094] Specifically, when the forming information of workpiece 200 indicates that workpiece 200 has been formed, the heating element 20 is controlled to perform heat treatment on the formed workpiece 200 to improve the hardness, wear resistance and toughness of workpiece 200.

[0095] Step S50: Obtain heat treatment information of workpiece 200, which includes whether workpiece 200 has been heat treated or not.

[0096] Specifically, the heat treatment information for workpiece 200 includes whether workpiece 200 has been heat-treated or not. "Workpiece 200 has been heat-treated" indicates that workpiece 200 has been heat-treated by the heating element 20, while "Workpiece 200 has not been heat-treated" indicates that workpiece 200 has not been heat-treated by the heating element 20. Obtaining this heat treatment information facilitates the secondary forming process that the forming part 10 performs on the heat-treated workpiece 200.

[0097] Step S60: Based on the heat treatment information of workpiece 200, workpiece 200 has been heat treated. The forming part 10 is controlled to form workpiece 200 in a second form, and it is determined that the outer contour of end 201 and inner hole 203 both retain a second preset allowance.

[0098] Specifically, when the heat treatment information of workpiece 200 indicates that workpiece 200 has been heat-treated, the forming part 10 controls the secondary forming of workpiece 200, and determines that the outer contour of end 201 and the inner hole 203 both retain a second preset allowance, so that the processing machine 100 can subsequently grind and process the outer contour of end 201 and the inner hole 203 respectively, while the remaining parts of workpiece 200 are formed to standard dimensions. In this embodiment, the second preset allowance is 0.03mm. It can be understood that the above-mentioned secondary forming refers to forming two or more times until workpiece 200 is formed to standard dimensions.

[0099] Thus, by executing the above steps S10-S60, based on the preset size information of the workpiece 200, the forming part 10 can form the workpiece 200, and the heating part 20 can heat treat the workpiece 200, so that the outer contour of the end 201 and the inner hole 203 both retain a second preset allowance, which facilitates the subsequent precise grinding of the workpiece 200 by the processing machine 100.

[0100] Please see Figure 2 The processing machine 100 also includes a spindle 30, a first clamping member 40, and a grinding member 50. The spindle 30 is adjacent to one side of the forming part 10 and the heating member 20. The first clamping member 40 is detachably connected to the spindle 30 and is used to clamp the workpiece 200 at a predetermined position. The spindle 30 is used to drive the first clamping member 40 to rotate. The grinding member 50 is adjacent to the first clamping member 40 and is used to grind the outer contour of the end 201 of the workpiece 200. In this embodiment, the spindle 30 can be a machine spindle 30, the first clamping member 40 can be any clamping part, clamping block, or similar clamping body capable of clamping the workpiece 200, and the grinding member 50 can be any grinding part, grinding block, or similar grinding body capable of grinding the workpiece 200, such as a grinding wheel.

[0101] Please see Figure 1A , Figure 1B The processing method of this application embodiment further includes the following steps S70-S130.

[0102] Step S70: Obtain the first clamping reference information of the first clamping member 40, the first workpiece reference information of the workpiece 200 to be ground, and the first spindle reference information of the spindle 30. The first clamping reference information is the reference point position information of the first clamping member 40, the first workpiece reference information is the reference point position information of the workpiece 200 to be ground, and the first spindle reference information is the reference point position information of the spindle 30.

[0103] Specifically, the first clamping component 40, the workpiece 200, and the spindle 30 are marked using a special pen or other marking device. The marked positions are the reference point positions of the first clamping component 40, the workpiece 200, and the spindle 30, thereby obtaining the first clamping reference information of the first clamping component 40, the first workpiece reference information of the workpiece 200 to be ground, and the first spindle reference information of the spindle 30, which facilitates the determination of the clamping angle and clamping position of the first clamping component 40.

[0104] Step S80: Based on the first clamping reference information, the first workpiece reference information and the first spindle reference information, determine the first clamping angle and the first clamping orientation of the first clamping member 40.

[0105] Specifically, based on the first clamping reference information, the first workpiece reference information, and the first spindle reference information, the marking points of the spindle 30, the first clamping member 40, and the workpiece 200 are aligned on a straight line to determine the first clamping angle and the first clamping orientation of the first clamping member 40. The spindle 30 has a central axis, a first line is formed between the central axis and the reference point of the spindle 30, and a second line is formed between the central axis and the reference point of the first clamping member 40. The angle between the first and second lines is the clamping angle of the first clamping member 40.

[0106] Step S90: Control the first clamping member 40 to clamp the workpiece 200 at a preset position according to the first clamping angle and the first clamping orientation.

[0107] Specifically, the first clamping member 40 is installed on the spindle 30 at a first clamping angle and clamps the workpiece 200 at a preset position according to the first clamping orientation, thereby forming a uniform clamping standard, which facilitates the standardized processing of the end 201 of the workpiece 200 by the processing machine 100. Understandably, the preset position refers to the position where the workpiece 200 is clamped by the first clamping member 40, while the end 201 of the workpiece 200 is not covered by the first clamping member 40, allowing the grinding member 50 to easily grind the outer contour of the end 201 of the workpiece 200.

[0108] Step S100: Obtain the clamping information of the first clamping member 40 and the dimension information of the end 201 of the workpiece 200. The clamping information of the first clamping member 40 includes whether the workpiece 200 is clamped or not.

[0109] Specifically, the clamping information of the first clamping member 40 includes whether the workpiece 200 is clamped or not. "Workpiece 200 is clamped" indicates that the workpiece 200 has been clamped by the first clamping member 40, and "Workpiece 200 is not clamped" indicates that the workpiece 200 has not been clamped by the first clamping member 40. This clamping information can be obtained by an operator or an industrial camera. By acquiring the clamping information of the first clamping member 40 and the dimension information of the end 201 of the workpiece 200, the clamping status of the workpiece 200 can be monitored, facilitating the grinding part 50 to grind the workpiece 200 that has been clamped by the first clamping member 40.

[0110] In step S110, based on the clamping information of the first clamping member 40, which indicates that the workpiece 200 is clamped and the size information of the end 201 of the workpiece 200, the grinding member 50 is controlled to grind the outer contour of the end 201 in a preset posture.

[0111] Specifically, when the clamping information of the first clamping member 40 indicates that the workpiece 200 has been clamped, and based on the size information of the end 201 of the workpiece 200, the grinding member 50 is controlled to grind the outer contour of the end 201 in a preset posture in one go, effectively reducing the error of the workpiece 200 caused by grinding.

[0112] Step S120: Obtain the line profile information of the end 201 of the workpiece 200 after one grinding.

[0113] Specifically, the end piece 201 is inspected using a line profiler or other testing equipment to obtain the line profile information of the end piece 201 after one grinding, so as to determine whether the line profile of the end piece 201 after one grinding is within the first preset range. Here, the above-mentioned "after one grinding" can be understood as the first grinding operation after the first clamping part 40 completes the clamping operation.

[0114] In step S130, based on the line contour information of the end 201 of the workpiece 200 after the first grinding, if the line contour of the end 201 of the workpiece 200 is within a first preset range, the first clamping angle is determined to be the optimal clamping angle. Conversely, if the line contour information of the end 201 of the workpiece 200 after the first grinding is outside the first preset range, the clamping angle of the first clamping member 40 is adjusted to the second clamping angle, and the grinding member 50 is controlled to grind the outer contour of the end 201 of the workpiece 200 a second time according to a preset posture, and the line contour information of the end 201 of the workpiece 200 after the second grinding is obtained. Based on the line contour information of the end 201 of the workpiece 200 after the second grinding, if the line contour of the end 201 of the workpiece 200 is within the first preset range, the second clamping angle is determined to be the optimal clamping angle.

[0115] Specifically, when the line profile of end 201 is within the first preset range, the first clamping angle can be determined as the optimal clamping angle. At this time, the machining error of end 201 after grinding is minimized, effectively reducing machining error. The first clamping component 40 is controlled to be installed on the spindle 30 according to the first clamping angle, and the workpiece 200 is clamped according to the first clamping orientation, so as to achieve batch processing of workpiece 200 according to the same standard. When the line profile of end 201 is outside the second preset range, it can be determined that the first clamping angle is not the optimal clamping angle. Then, the clamping angle of the first clamping component 40 is adjusted to the second clamping angle, and the grinding component 50 is controlled to perform secondary grinding to adjust the outer profile of end 201. Then, the line profile information of end 201 after secondary grinding is obtained. Based on the line profile information of end 201 of workpiece 200 after secondary grinding, the line profile of end 201 of workpiece 200 is within the first preset range, so the second clamping angle can be determined as the optimal clamping angle. At this time, the machining error of end 201 is minimized, effectively reducing machining error, so as to achieve batch processing of workpiece 200 according to the same standard. In this embodiment of the application, the first preset range is 0μm to 0.2μm. It can be understood that the above-mentioned secondary polishing refers to the polishing of the end 201 of the polishing part 50 being done two or more times.

[0116] Thus, by executing steps S70-S130, the first clamping orientation of the first clamping member 40 is determined based on the first clamping reference information, the first workpiece reference information, and the first spindle reference information. This enables multiple workpieces 200 to form the same clamping standard, thereby enabling the workpieces 200 to form the same processing standard for mass production. Based on the line profile of the end 201 within a first preset range, the optimal clamping angle of the first clamping member 40 can be determined, thereby making the first clamping member 40 suitable for the error of the spindle 30, thereby reducing the processing error of the workpiece 200. Furthermore, based on the grinding member 50 grinding the outer profile of the end 201 according to a preset posture, the error caused by the grinding method can be reduced, further reducing the processing error of the workpiece 200.

[0117] Please see Figure 5 In some embodiments, step S80 may specifically include the following steps S81-S82.

[0118] Step S81: Based on the first clamping reference information and the first workpiece reference information, control the reference point of the first clamping member 40 to correspond with the reference point of the workpiece 200, so as to determine the first clamping orientation of the first clamping member 40.

[0119] Specifically, based on the first clamping reference information and the first workpiece reference information, the reference point of the first clamping member 40 is controlled to correspond with the reference point of the workpiece 200, so that the marking point of the first clamping member 40 and the marking point of the workpiece 200 are on the same straight line, thereby determining the first clamping orientation of the first clamping member 40, so that the first clamping member 40 can clamp other workpieces 200 to be processed according to the first clamping orientation, thus realizing the same clamping orientation standard of the first clamping member 40.

[0120] Step S82: Based on the first clamping reference information and the first spindle reference information, control the reference point of the first clamping member 40 to correspond with the reference point of the spindle 30, so as to determine the first clamping angle of the first clamping member 40.

[0121] Specifically, based on the first clamping reference information and the first spindle reference information, the reference point of the first clamping component 40 is controlled to correspond with the reference point of the spindle 30, so that the marking point of the first clamping component 40 and the marking point of the spindle 30 are on the same straight line, thereby determining the first clamping angle of the first clamping component 40, so that the first clamping component 40 can be installed on the spindle 30 according to the first clamping angle, thus achieving the same clamping angle standard for the first clamping component 40.

[0122] Thus, by executing the above steps S81-S82, based on the first clamping orientation and the first clamping angle of the first clamping member 40, the first clamping member 40 forms the same clamping standard, which makes it easy for the first clamping member 40 to be connected to the spindle 30 and clamp the workpiece 200 according to the same clamping orientation and clamping angle, thereby enabling the workpiece 200 being processed to also form the same standard for batch processing and production of workpiece 200.

[0123] Please see Figure 6 In some embodiments, step S110 may specifically include the following steps S111 and S112.

[0124] Step S111: Based on the dimension information of the end 201 of the workpiece 200, the width dimension of the end 201 of the workpiece 200 is determined to be equal to the width dimension of the end 201 of the workpiece 200.

[0125] Specifically, by selecting and determining a grinding part 50 with a width of 50mm based on the size information of the end 201, for example, the width of the end 201 is 50mm, the grinding part 50 can completely cover the side wall of the end 201, making it convenient for the grinding part 50 to grind the outer contour of the end 201 according to the preset posture.

[0126] Step S112: Based on the clamping information of the first clamping member 40, the workpiece 200 is clamped. The grinding member 50 is controlled to grind the outer contour of the end 201 of the workpiece 200 in a preset posture. The preset posture is the grinding posture of the grinding member 50 advancing back and forth.

[0127] Specifically, based on the clamping information of the first clamping member 40, the workpiece 200 is clamped, and the grinding member 50 is controlled to grind the outer contour of the end 201 of the workpiece 200 in a forward and backward grinding posture. This allows the grinding member 50 to grind the outer contour of the end 201 in a single grinding posture, avoiding further increase in the error of the workpiece 200 caused by the grinding member 50 simultaneously moving forward and backward and laterally, thus effectively reducing the machining error of the workpiece 200. It can be understood that the forward and backward grinding posture refers to the grinding member 50 moving along a direction perpendicular to the extension of the workpiece 200 to grind the workpiece 200, while the lateral grinding posture refers to the grinding member 50 moving along the extension direction of the workpiece 200 to grind the workpiece 200.

[0128] Thus, by performing the above steps S111-S112, the grinding part 50 can grind the outer contour of the end 201 in a preset posture, avoiding the grinding part 50 from moving left and right at the same time as moving forward and backward, effectively reducing the machining error of the workpiece 200.

[0129] Please see Figure 7 In some embodiments, step S130 may specifically include the following steps S131-S135.

[0130] Step S131: Based on the line profile information of the end 201 after one grinding, the maximum error position of the end 201 is determined as the line profile of the end 201 of the workpiece 200 is outside the first preset range.

[0131] Specifically, if the line profile information of the end 201 after one grinding is found to be outside the first preset range, it can be known that the line profile of the end 201 is outside the first preset range due to the excessive error of the spindle 30. Based on this, the maximum error position of the end 201 can be determined by comparing the line profile of the end 201 with the standard size of the end 201.

[0132] Step S132: Based on the maximum error position of the end 201, control the first clamping member 40 to rotate relative to the main shaft 30, and adjust the clamping angle of the first clamping member 40 to the second clamping angle.

[0133] Specifically, since the grinding part 50 is set in a fixed position and the end 201 of the workpiece 200 has a preset avoidance position 202, by controlling the first clamping part 40 to rotate relative to the spindle 30 based on the maximum error position, the position formed by the maximum error position on the workpiece 200 can be changed, thereby adjusting the clamping angle of the first clamping part 40 to the second clamping angle, so that the first clamping part 40 is suitable for the error of the spindle 30, thereby adjusting the maximum error position of the workpiece 200 to the preset avoidance position 202 of the end 201, thereby reducing the error generated after the workpiece 200 is ground.

[0134] Step S133: Based on the second clamping angle, control the grinding part 50 to perform secondary grinding and adjustment according to the preset posture, and adjust the outer contour of the end 201 of the workpiece 200 clamped by the first clamping part 40.

[0135] Specifically, based on the second clamping angle, it can be determined that the first clamping member 40 has undergone clamping angle adjustment, preventing the grinding member 50 from grinding the workpiece 200 clamped by the first clamping member 40 that has not undergone angle adjustment, thereby controlling the outer contour of the secondary grinding end 201 of the grinding member 50. Understandably, the grinding posture of the secondary grinding of the grinding member 50 is the same as that of the primary grinding of the grinding member 50, and its grinding posture is also a forward and backward infeed posture.

[0136] Step S134: Obtain the line profile information of the end 201 of the workpiece 200 after secondary grinding.

[0137] Specifically, the line profile of the end 201 after secondary polishing is detected by a line profiler or other testing equipment to obtain the line profile information of the end 201 after secondary polishing, so as to compare the line profile with the first preset range.

[0138] Step S135: Based on the line profile information of the end 201 after secondary grinding, the line profile of the end 201 of the workpiece 200 is within the first preset range, and the second clamping angle is determined as the optimal clamping angle.

[0139] Specifically, by determining that the line profile information of the end 201 after secondary grinding is within the first preset range, the second clamping angle can be determined as the optimal clamping angle. At this time, the maximum error position of the workpiece 200 is located at the preset avoidance position 202 of the workpiece 200, reducing the machining error generated by the machining table 100 in machining the workpiece 200. If the line profile information of the end 201 after secondary grinding is outside the first preset range, then the second clamping angle is determined to be not the optimal clamping angle. Therefore, it is necessary to continue adjusting the clamping angle of the first clamping member 40, and continue grinding the workpiece 200 clamped by the adjusted first clamping member 40 until the line profile of the end 201 is within the first preset range.

[0140] Thus, by executing steps S131-S135 above, based on the fact that the line profile of the end 201 after the first grinding is outside the first preset range, the maximum error position of the end 201 is determined, thereby adjusting the clamping angle of the first clamping member 40 a second time, and grinding the workpiece clamped by the first clamping member 40 after the second grinding until the line profile of the end 201 after the second grinding is within the first preset range, and at the same time determining this angle as the optimal clamping angle, so that other workpieces 200 are clamped according to the optimal clamping angle, realizing the same standard batch processing of workpieces 200, while reducing the processing error of the end 201.

[0141] Please see Figure 8 In some embodiments, step S132 may specifically include the following steps S1321-S1322.

[0142] Step S1321: Based on the maximum error position of the end 201 of the workpiece 200 and the preset avoidance position 202 of the end 201 of the workpiece 200, determine the difference angle between the maximum error position and the preset avoidance position 202.

[0143] Specifically, the central axis of workpiece 200 has an origin on the end face of end 201. A first line is formed between the maximum error position and the origin, and a second line is formed between the preset avoidance position 202 and the origin. An angle is formed between the first and second lines, which is the angle difference between the maximum error position and the preset avoidance position 202. By determining the angle difference between the maximum error position and the preset avoidance position 202 based on the maximum error position and the preset avoidance position 202 of end 201, the clamping angle of the first clamping member 40 can be adjusted, thereby adjusting the maximum error position to the preset avoidance position 202.

[0144] Step S1322: Based on the difference angle, control the first clamping member 40 to rotate relative to the main shaft 30 by the difference angle, and adjust the clamping angle of the first clamping member 40 to the second clamping angle.

[0145] Specifically, by controlling the rotation difference angle of the first clamping member 40 relative to the spindle 30 based on the difference angle, the clamping angle of the first clamping member 40 can be adjusted to the second clamping angle, so that the workpiece 200 clamped by the first clamping member 40 also rotates, thereby adjusting the maximum error position of the workpiece 200 to the preset avoidance position 202, and further reducing the machining error.

[0146] Thus, by executing the above steps S1321-S1322, based on the angle difference between the maximum error position of the end 201 and the preset avoidance position 202, the maximum error position is adjusted to the preset avoidance position, further reducing the processing error.

[0147] Please see Figure 2 and Figure 4 In some embodiments, the machining table 100 further includes a second clamping member 60 and a machining element 70. The second clamping member 60 is detachably connected to the spindle 30 and is used to clamp the machined end 201. The machining element 70 is adjacent to the second clamping member 60 and is used to machine the inner hole 203 of the workpiece 200. In this embodiment, the second clamping member 60 can be any clamping part, clamping block, or similar clamping body capable of clamping the end 201. The second clamping member 60 replaces the first clamping member 40 connected to the spindle 30 when performing the inner hole 203 machining operation. The machining element 70 can be any machining part, machining block, or similar machining body capable of machining the inner hole 203.

[0148] Please see Figure 1B The processing method in this application embodiment further includes the following steps S140-S200.

[0149] Step S140: Obtain the second clamping reference information of the second clamping member 60, the second workpiece reference information of the machined end portion 201, and the second spindle reference information of the spindle 30. The second clamping reference information is the reference point information of the second clamping member 60, the second workpiece reference information is the reference point information of the machined end portion 201, and the second spindle reference information is another reference point information of the spindle 30.

[0150] Specifically, the second clamping component 60, the machined end portion 201, and the spindle 30 are marked using a special pen or other marking device. The marked positions are the reference point positions of the second clamping component 60, the machined end portion 201, and another reference point position of the spindle 30. This obtains the second clamping reference information of the second clamping component 60, the reference information of the machined end portion 201, and the second spindle reference information of the spindle 30, which facilitates the determination of the clamping position and clamping orientation of the second clamping component 60.

[0151] Step S150: Based on the second clamping reference information, the second workpiece reference information, and the second spindle reference information, determine the first clamping position and the second clamping orientation of the second clamping member 60.

[0152] Specifically, based on the second clamping reference information, the second workpiece reference information, and the second spindle reference information, the reference point of the second clamping member 60, the reference point of the end 201, and another reference point of the spindle 30 are adjusted to be on the same straight line, thereby determining the first clamping position and the second clamping orientation of the second clamping member 60.

[0153] Step S160: Control the second clamping member 60 to clamp onto the end 201 according to the first clamping position and the second clamping orientation.

[0154] Specifically, the second clamping member 60 is installed on the spindle 30 according to the first clamping position, and clamped on the machined end 201 according to the second clamping orientation, so that the second clamping member 60 forms the same clamping standard, which facilitates the standardized machining of the inner hole 203 of the workpiece 200 by the machining machine 100.

[0155] Step S170: Obtain the clamping information of the second clamping member 60. The clamping information of the second clamping member 60 includes whether the end 201 is clamped or not.

[0156] Specifically, the clamping information of the second clamping member 60 includes whether the end 201 is clamped or not. "End 201 clamped" indicates that the end 201 has been clamped by the second clamping member 60, and "End 201 not clamped" indicates that the end 201 is not clamped by the second clamping member 60. This clamping information can be obtained by an operator or an industrial camera. By obtaining this clamping information, the clamping status of the end 201 can be monitored, facilitating the machining of the inner hole 203 of the workpiece 200 by the machining part 70.

[0157] In step S180, based on the clamping information of the second clamping member 60 that the end 201 has been clamped, the machining member 70 is controlled to process the inner hole 203 of the workpiece 200 in one operation.

[0158] Specifically, by using the clamping information of the second clamping member 60 to determine that the end 201 of the workpiece 200 has been clamped, it is possible to control the machining member 70 to process the inner hole 203 of the workpiece 200 in one operation, thereby avoiding the machining member 70 from processing the end 201 of the workpiece 200 that has not been clamped.

[0159] Step S190: Obtain the coaxiality information of the inner hole 203 of the workpiece 200 after one machining.

[0160] Specifically, the inner hole 203 is inspected using a roundness tester or other testing equipment to obtain the coaxiality information of the inner hole 203 after one machining, so as to determine whether the coaxiality of the inner hole 203 after one machining is within the second preset range.

[0161] In step S200, based on the coaxiality information of the inner hole 203 of the workpiece 200 after one machining, if the coaxiality of the inner hole 203 of the workpiece 200 is within a second preset range, the first clamping position is determined as the optimal clamping position. Conversely, if the coaxiality information of the inner hole 203 of the workpiece 200 after one machining is outside the second preset range, the clamping position of the second clamping member 60 is adjusted to the second clamping position, and the machining member 70 is controlled to perform a second machining of the inner hole 203 of the workpiece 200 to obtain the inner hole 203 of the workpiece 200 after the second machining. Based on the coaxiality of the inner hole 203 of the workpiece 200 after the second machining being within the second preset range, the second clamping position is determined as the optimal clamping position.

[0162] Specifically, when the coaxiality of the inner hole 203 is within the second preset range, the second clamping position can be determined as the optimal clamping position. At this time, the machining error of the machined inner hole 203 is minimized, effectively reducing the machining error. The second clamping component 60 is controlled to be installed on the spindle 30 according to the first clamping position, and the subsequent workpiece 200 to be machined is clamped according to the second clamping orientation, thereby forming a standard batch production of workpieces 200. When the coaxiality of the inner hole 203 is outside the second preset range, it can be determined that the second clamping position is not the optimal clamping position. Then, the clamping position of the second clamping component 60 is adjusted to the second clamping position to determine that the coaxiality of the inner hole 203 is within the second preset range, and the second clamping position is determined as the optimal clamping position, effectively reducing the machining error, and simultaneously forming a standard batch production of workpieces 200. In the embodiment of the application, the second preset range is 0μm to 0.3μm.

[0163] Thus, by executing the above steps S140-S200, based on the second clamping reference information, the second workpiece reference information, and the second spindle reference information, the second clamping orientation of the second clamping member 60 is determined, enabling multiple workpieces 200 to form the same clamping standard when machining the inner hole 203, thereby enabling the inner hole 203 to form the same standard for batch processing of workpieces 200; based on the coaxiality of the inner hole 203 within a second preset range, the optimal clamping position of the second clamping member 60 can be determined, thereby making the second clamping member 60 suitable for the error of the spindle 30, thereby reducing the machining error of the inner hole 203.

[0164] Please see Figure 9 In some embodiments, step S150 may specifically include the following steps S151-S152.

[0165] Step S151: Based on the second clamping reference information and the second workpiece reference information, control the reference point of the second clamping member 60 to correspond with the reference point of the end 201, so as to determine the second clamping orientation of the second clamping member 60.

[0166] Specifically, based on the second clamping reference information and the second workpiece reference information, the reference point of the second clamping member 60 and the reference point of the end 201 are controlled to correspond, so that the marking point of the second clamping member 60 and the marking point of the end 201 are on the same straight line, thereby determining the second clamping orientation of the second clamping member 60, so that the second clamping member 60 clamps the end 201 of the workpiece 200 according to the second clamping orientation, thereby realizing the same clamping orientation standard of the second clamping member 60.

[0167] Step S152: Based on the second clamping reference information and the second spindle reference information, control the reference point of the second clamping member 60 to correspond with another reference point of the spindle 30, so as to determine the first clamping position of the second clamping member 60.

[0168] Specifically, based on the second clamping reference information and the second spindle reference information, the reference point of the second clamping component 60 is controlled to correspond with another reference point of the spindle 30, so that the mark point of the second clamping component 60 and another reference point of the spindle 30 are on the same straight line, thereby determining the first clamping position of the second clamping component 60, so that the second clamping component 60 can be installed on the spindle 30 according to the first clamping position, thus realizing the same clamping position standard for the second clamping component 60.

[0169] Thus, by performing the above steps S151-S152, the second clamping member 60 can clamp the end 201 according to the second clamping orientation and the second clamping position, thereby forming the same clamping orientation standard and clamping position standard for the second clamping member 60. This makes the inner hole 203 of the clamped workpiece 200 form the same coaxiality, which facilitates the processing machine 100 to achieve the same standard for batch processing of workpieces 200.

[0170] Please see Figure 10 In some embodiments, step S200 may specifically include the following steps S201-S205.

[0171] Step S201: Based on the coaxiality information of the inner hole 203 of the workpiece 200 after one machining, if the coaxiality of the inner hole 203 of the workpiece 200 is outside the second preset range, determine the offset direction and offset amount of the inner hole 203 of the workpiece 200.

[0172] Specifically, by using the coaxiality information of the inner hole 203 after one machining operation to determine that the coaxiality of the inner hole 203 is outside the second preset range, it can be known that the error of the spindle 30 causes the coaxiality of the inner hole 203 to be outside the second preset range. In this way, the central axis of the inner hole 203 is compared with the central axis of the workpiece 200 to determine the offset direction and offset amount of the inner hole 203.

[0173] In step S202, based on the offset direction and offset amount of the inner hole 203 of the workpiece 200, the second clamping member 60 is controlled to translate relative to the spindle 30, and the clamping position of the second clamping member 60 is adjusted to the second clamping position.

[0174] Specifically, by controlling the translation of the second clamping member 60 relative to the spindle 30 based on the offset direction and offset amount of the inner hole 203, the offset direction and offset amount of the inner hole 203 can be changed, so that the second clamping member 60 is adapted to the error of the spindle 30, thereby reducing the offset value of the central axis of the inner hole 203 relative to the central axis of the workpiece 200, and thus reducing the error generated after the inner hole 203 is machined.

[0175] Step S203: Based on the second clamping position, control the inner hole 203 of the workpiece 200 clamped by the second clamping member 60 after the workpiece 70 has been adjusted by secondary grinding.

[0176] Specifically, based on the second clamping position, it can be determined that the second clamping member 60 has undergone clamping position adjustment, preventing the workpiece 70 from processing the workpiece 200 clamped by the second clamping member 60 that has not undergone position adjustment, thereby controlling the inner hole 203 of the workpiece 200 clamped by the second clamping member 60 after the workpiece 70 has undergone secondary grinding adjustment.

[0177] Step S204: Obtain the coaxiality information of the inner hole 203 of the workpiece 200 after secondary processing.

[0178] Specifically, the inner hole 203 after secondary processing is inspected by a roundness tester or other testing equipment to obtain the coaxiality information of the inner hole 203 after secondary processing, so as to compare the coaxiality of the inner hole 203 after secondary processing with the second preset range.

[0179] Step S205: Based on the coaxiality information of the inner hole 203 of the workpiece 200 after secondary processing, the coaxiality of the inner hole 203 of the workpiece 200 is within the second preset range, and the second clamping position is determined as the optimal clamping position.

[0180] Specifically, by determining that the coaxiality of the inner hole 203 is within the second preset range based on the coaxiality information of the inner hole 203 after secondary machining, the second clamping position can be identified as the optimal clamping position, effectively reducing the error generated by the machining machine 100 machining the inner hole 203 of the workpiece 200. If the coaxiality information of the inner hole 203 after secondary machining is outside the second preset range, then the second clamping position is determined to be not the optimal clamping position. Therefore, it is necessary to continue adjusting the clamping position of the second clamping member 60 and continue machining the inner hole 203 of the workpiece 200 clamped by the adjusted second clamping member 60 until the coaxiality of the inner hole 203 is within the second preset range.

[0181] Thus, by executing the above steps S201-S205, when the coaxiality of the inner hole 203 is outside the second preset range, the offset direction and offset amount of the inner hole 203 can be determined, thereby controlling the second clamping member 60 to drive the workpiece 200 it clamps to translate, so as to determine that the coaxiality of the inner hole 203 after secondary processing is within the second preset range, thereby reducing the processing error of the inner hole 203.

[0182] The processing method provided in this application embodiment determines the first clamping orientation of the first clamping member 40 based on the first clamping reference information, the first workpiece reference information, and the first spindle reference information. This enables multiple workpieces 200 to form the same clamping standard, thereby enabling the workpieces 200 to be mass-produced according to the same standard. Based on the line profile of the end 201 within a first preset range, the optimal clamping angle of the first clamping member 40 can be determined, thereby making the first clamping member 40 suitable for the error of the spindle 30, thereby reducing the processing error of the workpiece 200. Furthermore, based on the grinding member 50 grinding the outer profile of the end 201 according to a preset posture, the error caused by the grinding method can be reduced, further reducing the processing error of the workpiece 200.

[0183] Please see Figure 11 This application also provides a processing system 300, which is applied to a processing machine 100 to reduce processing errors and achieve batch processing of workpieces 200 according to the same standard.

[0184] In some embodiments, the processing system 300 can be divided into multiple functional modules according to the functions it performs, and each functional module is used to perform the steps in the corresponding embodiments of the above processing method. In this embodiment, the functional modules of the processing system 300 include an acquisition module 301 and a processing module 302.

[0185] The acquisition module 301 is used to acquire the first clamping reference information of the first clamping member 40, the first workpiece reference information of the workpiece 200 to be ground, and the first spindle reference information of the spindle 30. The first clamping reference information is the reference point position information of the first clamping member 40, the first workpiece reference information is the reference point position information of the workpiece 200 to be ground, and the first spindle reference information is the reference point position information of the spindle 30. The acquisition module 301 is also used to acquire the clamping information of the first clamping member 40 and the end 201 dimension information of the workpiece 200. The clamping information of the first clamping member 40 includes whether the workpiece 200 is clamped or not. The acquisition module 301 is also used to acquire the line contour information of the end 201 of the workpiece 200 after one grinding and the line contour information of the end 201 of the workpiece 200 after a second grinding.

[0186] The machining module 302 is used to determine the first clamping angle and the first clamping orientation of the first clamping member 40 based on the first clamping reference information, the first workpiece reference information, and the first spindle reference information. The machining module 302 is also used to control the first clamping member 40 to clamp the workpiece 200 at a preset location according to the first clamping angle and the first clamping orientation. The machining module 302 is further used to control the grinding member 50 to grind the outer contour of the end 201 of the workpiece 200 in a preset posture based on the clamping information of the first clamping member 40 (the workpiece 200 is clamped) and the dimension information of the end 201 of the workpiece 200. The machining module 302 is also used to determine the workpiece's outer contour based on the line contour information of the end 201 of the workpiece 200 after one grinding operation.
