[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In one embodiment, if Figure 1 As shown, a workpiece clamping safety detection method is provided, comprising the following steps: S10: After clamping the workpiece to be processed, obtaining the projection area, actual contact area, workpiece height and projection surface perimeter corresponding to the workpiece to be processed.

[0020] Understandably, the workpiece to be processed refers to the part that needs to be processed. The projected area refers to the maximum outer area of ​​the workpiece obtained by looking down. The actual contact area refers to the contact area between the workpiece to be processed and the clamping magnetic table. The workpiece height refers to the height of the workpiece to be processed in the vertical direction. The projection surface perimeter refers to the perimeter of the projection surface of the workpiece to be processed on the horizontal plane.

[0021] Specifically, the processing data is obtained, and the processing data is parsed to obtain the workpiece to be processed, the processing machine tool, the clamping information and other data in the processing data, the workpiece to be processed is grabbed, the workpiece to be processed is moved to the processing machine tool, and the workpiece to be processed is fixed according to the clamping information. Then, after clamping the workpiece to be processed, the maximum outer shape area of ​​the workpiece to be processed in the top view corresponding to the top view angle and the actual contact area of ​​the workpiece to be processed and the clamping magnetic table are obtained to obtain the projection area and actual contact area corresponding to the workpiece to be processed. The workpiece height of the workpiece to be processed and the projection surface perimeter of the workpiece to be processed corresponding to the top view angle are obtained. Among them, the projection surface perimeter corresponding to the workpiece to be processed can be directly obtained through UG (Unigraphics NX, software system).

[0022] S20: Determine a contact area ratio corresponding to the workpiece to be processed according to the actual contact area and the projection area.

[0023] It can be understood that the contact area ratio refers to the ratio of the actual contact area to the projected area.

[0024] Specifically, an actual contact area corresponding to the workpiece to be processed is obtained, and then a ratio between the actual contact area and the projected area is determined as the contact area ratio.

[0025] S30: Obtaining a safety area ratio range corresponding to the workpiece to be processed according to the workpiece height and the perimeter of the projection surface.

[0026] It can be understood that the safe area ratio range refers to the ratio between the actual contact area and the projected area within a safe range.

[0027] Specifically, the ratio of the projected surface perimeter of the workpiece to be processed to the workpiece height is calculated. Then, the workpiece height safety parameter range corresponding to the workpiece to be processed in the preset safety ratio table is determined by the workpiece height. Next, the safety area ratio range corresponding to the workpiece to be processed is queried from the preset safety ratio table according to the workpiece height and the workpiece height safety parameter range.

[0028] S40: Obtain machining tool information and a tool safety parameter range corresponding to the workpiece to be machined, and perform clamping safety detection on the workpiece to be machined according to the contact area ratio, the safety area ratio range, the machining tool information and the tool safety parameter range, and obtain a safety detection result.

[0029] Understandably, the machining tool information refers to the information of the tool required to machine the workpiece, such as tool diameter, rotation speed, feed, etc. The tool safety parameter range refers to the safety range of the machining tool information. The safety detection result is used to indicate whether the workpiece to be machined is qualified for clamping.

[0030] Specifically, the processing tool information corresponding to the workpiece to be processed is obtained. Through the data of the workpiece to be processed, the tool safety parameter range corresponding to the workpiece to be processed is matched in the preset safety parameter table. Then, according to the contact area ratio, the safety area ratio range, the processing tool information and the tool safety parameter range, the clamping safety detection of the workpiece to be processed is performed, that is, the contact area ratio and the safety area ratio range are compared, and the processing tool information and the tool safety parameter range are compared, and the safety detection result is determined according to the area comparison result and the tool comparison result, that is, the content represented by the area comparison result and the tool comparison result is determined. When the area comparison result represents that the contact area ratio is greater than the safety area ratio range, and the tool comparison result represents that the processing tool information is within the tool safety parameter range, the safety detection result of the qualified clamping of the workpiece to be processed is obtained. When the content represented by one of the two comparison results is different from the above, the safety detection result of the unqualified clamping of the workpiece to be processed is determined.

[0031] In the workpiece clamping safety detection method of the present invention, after clamping the workpiece to be processed, the projected area, actual contact area, workpiece height and projection surface perimeter corresponding to the workpiece to be processed are obtained; according to the actual contact area and the projected area, the contact area ratio corresponding to the workpiece to be processed is determined; according to the workpiece height and the projection surface perimeter, the safety area ratio range corresponding to the workpiece to be processed is obtained; the machining tool information and tool safety parameter range corresponding to the workpiece to be processed are obtained, and according to the contact area ratio, the safety area ratio range, the machining tool information and the tool safety parameter range, the workpiece to be processed is clamped for safety detection, and the safety detection result is obtained. The present invention realizes the clamping safety detection of the workpiece to be processed through the contact area ratio, the safety area ratio range, the machining tool information and the tool safety parameter range, thereby ensuring the stable clamping of the workpiece to be processed, avoiding the movement of the workpiece and the collision of the machine tool, and thus improving the clamping efficiency and accuracy of the workpiece.

[0032] In one embodiment, in step S30, obtaining a safety area ratio range corresponding to the workpiece to be processed according to the workpiece height and the projection surface perimeter includes: S301, determining a workpiece height safety parameter range according to the workpiece height and the projection surface perimeter.

[0033] S302, querying in a preset safety ratio table to obtain a safety area ratio range corresponding to the workpiece height and the workpiece height safety parameter range.

[0034] Understandably, the workpiece height safety parameter range refers to the safety parameter range corresponding to the ratio of the projection surface perimeter to the workpiece height. The safety area ratio range refers to the safety ratio range corresponding to the workpiece height and the workpiece height safety parameter range. The preset safety ratio table refers to a table of safety ratios corresponding to the safety parameter ranges of various workpiece heights set in advance.

[0035] Specifically, the workpiece height of the workpiece to be processed and the perimeter of the projection surface corresponding to the workpiece to be processed are obtained, that is, the workpiece height of the workpiece to be processed can be directly obtained, or after the workpiece to be processed is fixed, the height of the workpiece to be processed is measured to obtain the workpiece height. At the same time, the perimeter of the projection surface of the workpiece to be processed is measured to obtain the perimeter of the projection surface corresponding to the workpiece to be processed, or the perimeter of the projection surface corresponding to the workpiece to be processed is directly obtained through UG (Unigraphics NX, software system). Next, the ratio between the perimeter of the projection surface and the height of the workpiece is calculated, and the ratio is determined as the workpiece height ratio. Obtain the preset safety ratio table, first determine the table position of the workpiece height, and determine the workpiece height safety parameter range corresponding to the workpiece height ratio in the preset safety ratio table. Finally, the safety ratio range corresponding to the workpiece to be processed in the preset safety ratio table is determined as the safety area ratio range.

[0036] In this embodiment, the workpiece height and the projection surface perimeter are used to calculate the workpiece height safety parameter range. By presetting the safety ratio table, the safety area ratio range is queried, thereby realizing the clamping safety detection of the workpiece to be processed.

[0037] In one embodiment, in step S40, that is, according to the contact area ratio, the safety area ratio range, the machining tool information and the tool safety parameter range, a clamping safety detection is performed on the workpiece to be machined, so as to determine whether to issue an alarm message according to the safety detection result, including: S401, comparing the contact area ratio and the safety area ratio range to obtain an area comparison result.

[0038] S402, comparing the machining tool information and the tool safety parameter range to obtain a parameter comparison result.

[0039] S403, performing a clamping safety inspection on the workpiece to be processed according to the area comparison result and the parameter comparison result to obtain a safety inspection result.

[0040] Understandably, the area comparison result is used to characterize the size of the contact area ratio and the safety area ratio range. The parameter comparison result is used to characterize whether the machining tool information conforms to the tool safety parameter range.

[0041] Specifically, after obtaining the safety parameter range, the contact area ratio and the safety area ratio range are compared, that is, the contact area ratio of the workpiece to be processed and the safety area ratio range are compared, so as to determine whether the contact area ratio meets the safety area ratio range, and the area comparison result can be obtained. Similarly, the machining tool information and the tool safety parameter range are compared, that is, the tool parameters in the machining tool information are compared with the tool safety parameter range, so as to determine whether the tool parameters meet the tool safety parameter range, and the parameter comparison result can be obtained. Furthermore, according to the area comparison result and the parameter comparison result, the clamping safety detection is performed on the workpiece to be processed, that is, through the content represented by the area comparison result and the parameter comparison result, it is judged whether the workpiece to be processed is clamped qualified, so as to obtain the safety detection result.

[0042] In this embodiment, the area comparison results and parameter comparison results are obtained, thereby obtaining the safety detection results, thereby improving the efficiency and accuracy of clamping safety detection.

[0043] In one embodiment, the step S403, i.e., performing a clamping safety inspection on the workpiece to be processed to obtain a safety inspection result, includes: S4031, when the area comparison result indicates that the contact area ratio is greater than the safety area ratio range, and the parameter comparison result indicates that the tool safety parameter range is greater than the machining tool information, a safety inspection result indicating that the workpiece to be machined is clamped properly is obtained, and the material preparation is confirmed to be completed.

[0044] Specifically, when the area comparison result indicates that the contact area ratio is greater than the minimum value in the safety area ratio range, and the parameter comparison result indicates that the machining tool information is within the tool safety parameter range, ensure that all conditions meet the requirements, thereby obtaining a safety inspection result indicating that the workpiece to be machined is clamped properly, and determine that there is no risk of movement of the workpiece to be machined, do not issue an alarm message to prompt, and confirm that material preparation is completed.

[0045] In this embodiment, by comparing the contents represented by the results, it is possible to determine whether the clamping is qualified, thereby determining whether to issue an alarm message, thereby improving the efficiency and accuracy of the clamping safety detection.

[0046] In one embodiment, the step S403, i.e., performing a clamping safety inspection on the workpiece to be processed to obtain a safety inspection result, further includes: S4032, when the area comparison result indicates that the contact area ratio is greater than the safety area ratio range, and the parameter comparison result indicates that the tool safety parameter range is less than or equal to the machining tool information, a safety detection result indicating that the clamping of the workpiece to be machined is unqualified is obtained, and a first alarm message is generated. The first alarm message is used to prompt that the machining tool information exceeds the tool safety parameter range.

[0047] Specifically, when the area comparison result indicates that the contact area ratio exceeds the safety area ratio range, and the parameter comparison result indicates that the tool safety parameter range is less than or equal to the machining tool information, one of the conditions does not meet the requirements, that is, when the area comparison result indicates that the contact area ratio is less than the minimum value of the safety area ratio range, or is greater than the maximum value of the safety area ratio range, or the parameter comparison result indicates that the tool safety parameter range is less than or equal to the machining tool information, when one of the above conditions exists, a safety detection result indicating that the clamping of the workpiece to be processed is unqualified is obtained, so as to determine the first alarm information that the machining tool information does not meet the requirements and confirm whether to replace the fixture and re-prepare the material.

[0048] In this embodiment, by comparing the contents represented by the results, it is possible to determine whether the fixation is qualified, thereby determining whether an alarm message is issued, and further providing a prompt for whether the fixture needs to be replaced, thereby improving the efficiency and accuracy of clamping safety detection.

[0049] In one embodiment, the step S403, i.e., performing a clamping safety inspection on the workpiece to be processed to obtain a safety inspection result, further includes: S4033, when the area comparison result indicates that the contact area ratio is less than or equal to the safety area ratio range, obtaining a preset ratio condition, and detecting the contact area ratio according to all the preset ratio conditions.

[0050] S4034: When the contact area ratio satisfies all the preset ratio conditions, determine whether the machining tool information is within the tool safety parameter range.

[0051] S4035, when the machining tool information is within the tool safety parameter range, a safety detection result indicating that the workpiece to be machined is clamped properly is obtained, and completion of material preparation is confirmed.

[0052] S4036, when the machining tool information exceeds the tool safety parameter range, a safety detection result indicating that the clamping of the workpiece to be machined is unqualified is obtained, and a first alarm message is generated, wherein the first alarm message is used to prompt that the machining tool information exceeds the tool safety parameter range.

[0053] It can be understood that the preset proportion condition refers to a judgment condition set in advance, for example, whether the difference in the contact surface proportion on both sides of the center line is within the error range, etc.

[0054] Specifically, after obtaining the safety detection result, when the area comparison result indicates that the contact area ratio is less than or equal to the safety area ratio range, the preset ratio condition is obtained, and the contact area ratio is detected according to all the preset ratio conditions, that is, whether the contact area ratio meets all the preset ratio conditions, for example, whether the contact area ratio on both sides of the center line is within the preset ratio condition range, and whether the difference in the contact area ratio on both sides of the center line is within the error range. When the contact area ratio meets all the preset ratio conditions, that is, the contact area ratio on both sides of the center line is within the preset ratio condition range, and the difference in the contact area ratio on both sides of the center line is within the error range, it is determined whether the machining tool information is within the tool safety parameter range. When the machining tool information is within the tool safety parameter range, a safety detection result indicating that the workpiece to be machined is clamped properly is obtained to determine that no alarm information is issued, and to confirm that the material preparation is completed. Further, when one or more of the tool parameters of the machining tool information exceeds the tool safety parameter range, a safety detection result indicating that the workpiece to be machined is clamped unqualified is obtained, and it is determined to issue a first alarm information indicating that the machining tool information exceeds the tool safety parameter range, so as to confirm whether to replace the fixture and re-prepare the material through the first alarm information.

[0055] In this embodiment, when the contact area ratio is less than or equal to the safe area ratio range, the preset ratio condition is used to determine whether there is a loose risk, thereby realizing the detection of the contact area ratio. By determining whether the machining tool information is within the tool safety parameter range, it is possible to determine whether an alarm message is issued, thereby realizing the determination of whether the material preparation is completed.

[0056] In one embodiment, after step S4033, that is, after detecting the contact area proportion according to all the preset proportion conditions, the method further includes: S4037: When the contact area ratio does not satisfy any of the preset ratio conditions, determine whether the machining tool information is within the tool safety parameter range.

[0057] S4038, when the machining tool information is within the tool safety parameter range, a safety detection result indicating that the clamping of the workpiece to be machined is unqualified is obtained, and a second warning message is generated, wherein the second warning message is used to warn that there is a risk in the clamping method.

[0058] S4039, when the processing tool information exceeds the tool safety parameter range, a safety detection result indicating that the clamping of the workpiece to be processed is unqualified is obtained, and a third alarm message is generated. The third alarm message is used to warn that there is a risk in the clamping method and that the processing tool information exceeds the tool safety parameter range.

[0059] Specifically, when the contact area ratio does not satisfy at least one preset ratio condition, that is, when the contact area ratio on both sides of the center line exceeds the preset ratio condition, or when the difference in the contact area ratio on both sides of the center line exceeds the error range, it is determined whether the machining tool information is within the tool safety parameter range. When the machining tool information is within the tool safety parameter range, a safety detection result is obtained that indicates that the clamping of the workpiece to be machined is unqualified, so as to determine whether to issue a second alarm message indicating that the clamping method has a risk of loosening, and confirm whether to replace the fixture and re-prepare the material through the second alarm message. When one or more of the tool parameters of the machining tool information exceeds the tool safety parameter range, a safety detection result is obtained that indicates that the clamping of the workpiece to be machined is unqualified, so as to determine whether to issue a third alarm message indicating that the clamping method has a risk of loosening and the machining tool information exceeds the safety parameter range, and confirm whether to replace the fixture and re-prepare the material through the third alarm message.

[0060] In this embodiment, when the contact area ratio does not meet at least one preset ratio condition, the content of the alarm information is determined by judging whether the processing tool information is within the tool safety parameter range, and the alarm information is accurately prompted, thereby avoiding problems caused by workpiece movement.

[0061] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

[0062] In one embodiment, a workpiece clamping safety detection device is provided, and the workpiece clamping safety detection device corresponds one-to-one to the workpiece clamping safety detection method in the above embodiment.
