Description

Technical Field

[0001] This invention relates to the field of core sample cutting technology, and more specifically, to a clamping adjustment method and system for a core sample line spacing cutting device. Background Technology

[0002] During the cutting of core samples, proper control of clamping force is crucial to ensuring cutting accuracy and sample quality. Traditional core sample line spacing cutting devices have many shortcomings in clamping adjustment.

[0003] On the one hand, the monitoring of clamping status lacks precision. Previously, the clamping condition was largely determined by operator experience or simple physical measurements, failing to provide real-time and intuitive information about the contact surface between the clamping head and the core sample. For example, it's impossible to promptly detect whether the contact between the clamping head and the core sample is uniform, or whether there are any abnormal offsets or gaps. If local gaps exist on the contact surface, the core sample may shift under the cutting force during cutting, severely affecting the accuracy of the cutting line spacing and leading to decreased cutting precision, failing to meet the requirements for high-precision cutting of core samples. On the other hand, the control of clamping force lacks intelligence. Traditional methods often use fixed clamping force settings, failing to consider the different clamping force requirements of core samples with varying hardness and volume. Harder cores require greater clamping force to prevent movement during cutting, while larger samples may require dispersed and uniform clamping force to avoid damage caused by localized stress concentration. Fixed clamping force settings may result in excessive clamping force damaging the sample, or insufficient clamping force causing sample movement during cutting, reducing the adaptability of the cutting device to different types of core samples. Furthermore, the clamping force adjustment is not flexible or precise enough. Traditional methods cannot dynamically adjust the clamping force according to actual cutting needs, and cannot guarantee that the core sample is always in the optimal clamping state during the cutting process. Moreover, there is a lack of refined calibration of the clamping force, and the clamping force is not further optimized based on the actual contact between the sample and the clamping head, making it difficult to maximize cutting accuracy and sample quality.

[0004] Therefore, it is necessary to provide a clamping adjustment method and system for a core sample line spacing cutting device to solve the problem that the clamping force cannot be reasonably controlled during the cutting process of core samples in the prior art. Summary of the Invention

[0005] In view of this, the present invention proposes a clamping adjustment method and system for a core sample line spacing cutting device, which aims to solve the problem that the clamping force cannot be reasonably controlled during the cutting process of core samples in the prior art.

[0006] On one hand, the present invention proposes a clamping adjustment method for a core sample line spacing cutting device, comprising: An image acquisition device is installed on the side wall of the clamping head to acquire images of the contact surface between the clamping head and the core sample in real time. Obtain the hardness and volume data of the current core sample, as well as the target volume of the target core sample, and preliminarily determine the clamping force based on the hardness and volume data; Based on the volume data and the target volume, determine whether the clamping force needs to be adjusted. If it is determined that adjustment is needed, then adjust the clamping force to obtain the clamping adjustment value. Based on the contact surface image, determine whether the clamping adjustment value needs to be corrected. If it is determined that correction is needed, then correct the clamping adjustment value based on the contact surface image to obtain the final clamping force value.

[0007] Furthermore, when initially determining the clamping force based on the hardness data and volume data, the process includes: Set a hardness threshold and a volume threshold. If the hardness data is greater than or equal to the hardness threshold and the volume data is greater than or equal to the volume threshold, then the clamping force is initially determined to be the first clamping force. If the hardness data is less than the hardness threshold and the volume data is greater than or equal to the volume threshold, then the clamping force is initially determined to be the second clamping force. If the hardness data is greater than or equal to the hardness threshold and the volume data is less than the volume threshold, then the clamping force is initially determined to be the second clamping force. If the hardness data is less than the hardness threshold and the volume data is less than the volume threshold, then the clamping force is initially determined to be the third clamping force. Among them, the first clamping force > the second clamping force > the third clamping force.

[0008] Furthermore, when determining whether to adjust the clamping force based on the volume data and the target volume, the following steps are included: Calculate the volume difference between the volume data and the target volume, and determine whether to adjust the clamping force based on the volume difference.

[0009] Furthermore, when determining whether to adjust the clamping force based on the volume difference, the process includes: If the volume difference value is greater than the preset volume difference threshold, it is determined that the clamping force needs to be adjusted; otherwise, it is determined that the volume difference threshold will not be adjusted, and the clamping force will be directly used as the clamping adjustment value.

[0010] Furthermore, when adjusting the clamping force to obtain the clamping adjustment value, the process includes: Calculate the sum of the volumes of the target volume and the volume difference threshold; When the volume data of the core sample equals the sum of the volumes, it is determined that the clamping force should be adjusted.

[0011] Furthermore, when adjusting the clamping force to obtain the clamping adjustment value, the method further includes: A first volume sum and a second volume sum are preset, wherein the first volume sum and the second volume sum are greater than the second volume sum and the second volume sum. The clamping force is adjusted according to the volume and value; If the sum of volumes is greater than the first sum of volumes, the clamping force is adjusted using a first adjustment coefficient; if the sum of volumes is less than or equal to the first sum of volumes and greater than or equal to the second sum of volumes, the clamping force is adjusted using a second adjustment coefficient; if the sum of volumes is less than the second sum of volumes, the clamping force is adjusted using a third adjustment coefficient; wherein the range of the adjustment coefficients is 1 > first adjustment coefficient > second adjustment coefficient > third adjustment coefficient > 0.5; and the clamping adjustment value is the product of the clamping force and the adjustment coefficient.

[0012] Furthermore, when determining whether to correct the clamping adjustment value based on the contact surface image, the following steps are included: Acquire images of the contact surface to determine whether the core sample has shifted or deformed; if it is determined that shifting or deformation has occurred, then it is determined that the clamping adjustment value needs to be corrected. Otherwise, it is determined that there is no need to correct the clamping adjustment value, and the clamping adjustment value is directly used as the final clamping force value.

[0013] Furthermore, when correcting the clamping adjustment value based on the contact surface image to obtain the final clamping force value, the following steps are included: When a deviation occurs, the deviation area is obtained, a first correction coefficient is determined based on the deviation area, and the clamping adjustment value is corrected using the first correction coefficient. The offset area is proportional to the first correction coefficient, and the value of the first correction coefficient is in the range of 1 < first correction coefficient < 1.5; and the final value of the clamping force is the product of the clamping adjustment value and the first correction coefficient.

[0014] Furthermore, when correcting the clamping adjustment value based on the contact surface image to obtain the final clamping force value, the following steps are included: When deformation occurs, the deformation area is obtained, a second correction coefficient is determined based on the deformation area, and the clamping adjustment value is corrected using the second correction coefficient. The deformation area is inversely proportional to the second correction coefficient, and the value range of the second correction coefficient is 1 > 0.5; and the final value of the clamping force is the product of the clamping adjustment value and the second correction coefficient.

[0015] Compared with existing technologies, the advantages of this invention are as follows: An image acquisition device is installed on the side wall of the clamping head to acquire real-time images of the contact surface, improving the ability to accurately monitor the clamping state. Through intuitive image information, operators can promptly detect whether the contact between the clamping head and the core sample is uniform, and whether there are any abnormal offsets or gaps, thereby preventing cutting deviations caused by poor contact and ensuring cutting accuracy. For example, if there are local gaps on the contact surface, the core sample may shift under the cutting force during cutting, seriously affecting the accuracy of the cutting line spacing. Real-time image monitoring can promptly detect such problems and make adjustments. Secondly, by acquiring the hardness and volume data of the core sample and preliminarily determining the clamping force, intelligent clamping force control is achieved. Core samples of different hardness and volume have different clamping force requirements. Harder cores require greater clamping force to prevent movement during cutting, while larger samples may require dispersed and uniform clamping force to avoid damage caused by local stress concentration. This method of determining clamping force based on sample characteristics ensures effective clamping while avoiding adverse effects on the sample due to excessive or insufficient clamping force, thus improving the adaptability of the cutting device to different types of core samples. Furthermore, by determining whether to adjust the clamping force based on volume data and the target volume, and obtaining the adjusted clamping value, the control of the clamping force is further optimized. This allows the clamping force to be dynamically adjusted according to actual cutting needs, ensuring that the core sample is always in an optimal clamping state during the cutting process. Finally, the clamping adjustment value is corrected based on the contact surface image to obtain the final clamping force value, achieving fine-grained calibration of the clamping force. Combined with real-time contact surface image information, the actual contact between the sample and the clamping head can be considered more accurately, further optimizing the clamping force and maximizing cutting accuracy and sample quality. In summary, this clamping adjustment method ensures reasonable control of the clamping force during core sample cutting from multiple dimensions.

[0016] On the other hand, this application also provides a clamping adjustment system for a core sample spacing cutting device, comprising: An image acquisition device is installed on the side wall of the clamping head. The image acquisition device is used to acquire images of the contact surface between the clamping head and the core sample in real time. The acquisition module is used to acquire the hardness and volume data of the current core sample, as well as the target volume of the target core sample, and to preliminarily determine the clamping force based on the hardness and volume data. The adjustment module is used to determine whether to adjust the clamping force based on the volume data and the target volume. If it is determined that adjustment is needed, the clamping force is adjusted to obtain a clamping adjustment value. The correction module is used to determine whether the clamping adjustment value needs to be corrected based on the contact surface image. If it is determined that correction is needed, the clamping adjustment value is corrected based on the contact surface image to obtain the final clamping force value.

[0017] It is understood that the clamping adjustment method and system for the core sample line spacing cutting device provided in this application have the same beneficial effects, and will not be described in detail here. Attached Figure Description

Detailed Implementation

While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein.

It should be noted that, unless otherwise specified, embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] In some embodiments of this application, see Figure 1 As shown, this embodiment provides a clamping adjustment method for a core sample line spacing cutting device, including the following steps: S100. An image acquisition device is installed on the side wall of the clamping head to acquire images of the contact surface between the clamping head and the core sample in real time. S200: Obtain the hardness and volume data of the current core sample, as well as the target volume of the target core sample, and preliminarily determine the clamping force based on the hardness and volume data. S300. Determine whether to adjust the clamping force based on the volume data and the target volume.

Determine whether to correct the clamping adjustment value based on the contact surface image. If it is determined that correction is needed, correct the clamping adjustment value based on the contact surface image to obtain the final clamping force value.

[0021] Understandably, installing an image acquisition device on the side wall of the clamping head to acquire real-time images of the contact surface enhances the ability to accurately monitor the clamping status. Through intuitive image information, operators can promptly detect whether the contact between the clamping head and the core sample is uniform, and whether there are any abnormal offsets or gaps, thus preventing cutting deviations caused by poor contact and ensuring cutting accuracy. For example, if there are local gaps on the contact surface, the core sample may shift under the cutting force during cutting, severely affecting the accuracy of the cutting line spacing. Real-time image monitoring can promptly detect such problems and make adjustments. Secondly, acquiring the hardness and volume data of the core sample and using this data to preliminarily determine the clamping force enables intelligent clamping force control. Core samples of different hardness and volume have different clamping force requirements. Harder cores require greater clamping force to prevent movement during cutting, while larger samples may require a dispersed and uniform clamping force to avoid damage caused by localized stress concentration. This method of determining clamping force based on sample characteristics ensures effective clamping while avoiding adverse effects on the sample due to excessive or insufficient clamping force, thus improving the adaptability of the cutting device to different types of core samples. Furthermore, by determining whether to adjust the clamping force based on volume data and the target volume, and obtaining the adjusted clamping value, the control of the clamping force is further optimized. This allows the clamping force to be dynamically adjusted according to actual cutting needs, ensuring that the core sample is always in an optimal clamping state during the cutting process. Finally, the clamping adjustment value is corrected based on the contact surface image to obtain the final clamping force value, achieving fine-grained calibration of the clamping force. Combined with real-time contact surface image information, the actual contact between the sample and the clamping head can be considered more accurately, further optimizing the clamping force and maximizing cutting accuracy and sample quality. In summary, this clamping adjustment method ensures reasonable control of the clamping force during core sample cutting from multiple dimensions.

[0022] In some embodiments of this application, the step of initially determining the clamping force based on the hardness data and volume data includes: Set a hardness threshold and a volume threshold. If the hardness data is greater than or equal to the hardness threshold and the volume data is greater than or equal to the volume threshold, then the clamping force is initially determined to be the first clamping force. If the hardness data is less than the hardness threshold and the volume data is greater than or equal to the volume threshold, then the clamping force is initially determined to be the second clamping force. If the hardness data is greater than or equal to the hardness threshold and the volume data is less than the volume threshold, then the clamping force is initially determined to be the second clamping force. If the hardness data is less than the hardness threshold and the volume data is less than the volume threshold, then the clamping force is initially determined to be the third clamping force. Among them, the first clamping force > the second clamping force > the third clamping force.

[0023] Understandably, this invention enables precise and reasonable clamping force control for core samples with different characteristics. By setting hardness and volume thresholds, appropriate clamping forces are matched to core samples with different combinations of hardness and volume, avoiding a one-size-fits-all fixed clamping force setting. For samples with high hardness and large volume, the maximum first clamping force is used to ensure stability and prevent movement during cutting; for samples with low hardness but large volume or high hardness but small volume, a second clamping force is used to ensure clamping effectiveness while preventing damage caused by localized stress concentration due to excessive clamping force; for samples with low hardness and small volume, the minimum third clamping force is used to meet clamping requirements while avoiding over-clamping. This allows the cutting device to better adapt to various core samples, effectively improving cutting stability and accuracy, and ensuring cutting quality.

[0024] Specifically, for example, when cutting a batch of core samples, if one core sample is harder and its volume exceeds a set volume threshold, the first clamping force is initially determined according to the rules. If a uniformly smaller clamping force is used, it may not be able to hold the harder core sample, resulting in cutting deviation; if a uniformly larger clamping force is used, it may damage other samples with lower hardness and smaller volume.

[0025] In some embodiments of this application, determining whether to adjust the clamping force based on the volume data and the target volume includes: Calculate the volume difference between the volume data and the target volume, and determine whether to adjust the clamping force based on the volume difference.

[0026] In some embodiments of this application, determining whether to adjust the clamping force based on the volume difference includes: If the volume difference value is greater than the preset volume difference threshold, it is determined that the clamping force needs to be adjusted; otherwise, it is determined that the volume difference threshold will not be adjusted, and the clamping force will be directly used as the clamping adjustment value.

[0027] In some embodiments of this application, adjusting the clamping force to obtain a clamping adjustment value includes: Calculate the sum of the volumes of the target volume and the volume difference threshold; When the volume data of the core sample equals the sum of the volumes, it is determined that the clamping force should be adjusted.

[0028] In some embodiments of this application, adjusting the clamping force to obtain a clamping adjustment value further includes: A first volume sum and a second volume sum are preset, wherein the first volume sum and the second volume sum are greater than the second volume sum and the second volume sum. The clamping force is adjusted according to the volume and value; If the sum of volumes is greater than the first sum of volumes, the clamping force is adjusted using a first adjustment coefficient; if the sum of volumes is less than or equal to the first sum of volumes and greater than or equal to the second sum of volumes, the clamping force is adjusted using a second adjustment coefficient; if the sum of volumes is less than the second sum of volumes, the clamping force is adjusted using a third adjustment coefficient; wherein the range of the adjustment coefficients is 1 > first adjustment coefficient > second adjustment coefficient > third adjustment coefficient > 0.5; and the clamping adjustment value is the product of the clamping force and the adjustment coefficient.

[0029] Understandably, the method of determining whether and how to adjust the clamping force in this invention is based on the difference between the actual volume and the target volume of the core sample, enabling precise and dynamic adjustment of the clamping force. By calculating the volume difference and comparing it with a pre-set volume difference threshold, the system can accurately identify situations requiring clamping force adjustment, avoiding unnecessary adjustments. Furthermore, by calculating the volume and value and setting different adjustment coefficients based on different volume and value ranges, the clamping force is adjusted more scientifically and rationally. This allows the system to adapt the most suitable clamping force according to the specific volume of the core sample, effectively ensuring that the core sample remains in a stable clamped state during the cutting process, improving cutting accuracy and sample quality, and enhancing the adaptability of the device to core samples of different volumes.

[0030] Specifically, for example, a batch of core samples needs to be cut. The target volume is set at 100 cubic centimeters, the pre-set volume difference threshold is 5 cubic centimeters, the first volume sum is 110 cubic centimeters, and the second volume sum is 90 cubic centimeters. One core sample has a volume of 115 cubic centimeters, which is 15 cubic centimeters different from the target volume, exceeding the volume difference threshold. Therefore, the clamping force needs to be adjusted. The calculated volume sum of the volume data and the volume difference threshold is 110 cubic centimeters. This volume sum equals the first volume sum. According to the rules, the initially determined clamping force is adjusted using the first adjustment coefficient (0.8) to obtain the clamping adjustment value. If the initial clamping force is 100N, then the clamping adjustment value is 100N × 0.8 = 80N, thus making the clamping force more suitable for the core sample and ensuring stable and accurate cutting.

[0031] In some embodiments of this application, determining whether to correct the clamping adjustment value based on the contact surface image includes: Acquire images of the contact surface to determine whether the core sample has shifted or deformed; if it is determined that shifting or deformation has occurred, then it is determined that the clamping adjustment value needs to be corrected. Otherwise, it is determined that there is no need to correct the clamping adjustment value, and the clamping adjustment value is directly used as the final clamping force value.

[0032] Understandably, acquiring images of the contact surface to determine whether the core sample has shifted or deformed, and thus deciding whether to correct the clamping adjustment value, allows for real-time monitoring of the core sample's state during clamping. This enables timely detection of potential shifts or deformations, preventing inaccurate experimental data or experimental failures due to abnormal core sample conditions. Secondly, based on accurate state assessment, correcting the clamping adjustment value if the core sample shifts or deforms ensures the clamping force remains appropriate, guaranteeing the stability and reliability of the core sample during experiments. If no shift or deformation occurs, the clamping adjustment value is directly used as the final clamping force value, avoiding unnecessary corrections, improving work efficiency, and reducing time costs and operational errors caused by over-adjustment.

[0033] In some embodiments of this application, when correcting the clamping adjustment value based on the contact surface image to obtain the final clamping force value, the following steps are included: When a deviation occurs, the deviation area is obtained, a first correction coefficient is determined based on the deviation area, and the clamping adjustment value is corrected using the first correction coefficient. The offset area is proportional to the first correction coefficient, and the value of the first correction coefficient is in the range of 1 < first correction coefficient < 1.5; and the final value of the clamping force is the product of the clamping adjustment value and the first correction coefficient.

[0034] Understandably, the method of determining the clamping adjustment value based on the offset area in this invention can more accurately take into account the actual situation of offset that occurs when the core sample comes into contact with the clamping head. Since the offset area is proportional to the first correction coefficient and its value range is limited to 1 < first correction coefficient < 1.5, the clamping force can be adjusted reasonably according to the degree of offset, avoiding insufficient clamping force due to offset that affects cutting accuracy, while avoiding excessive correction that causes excessive clamping force that damages the sample. Finally, the precise final clamping force value is obtained by multiplying the clamping adjustment value and the first correction coefficient, maximizing cutting accuracy and sample quality.

[0035] Specifically, for example, in a core sample cutting operation, the clamping adjustment value has been set to 120N. An image of the contact surface acquired by the image acquisition device shows that the core sample has shifted, with a calculated shift area of ​​5 square centimeters. Based on the pre-set relationship between the shift area and the first correction coefficient, the first correction coefficient is determined to be 1.2 (because the shift area is directly proportional to the first correction coefficient and is within the specified range). Therefore, the final clamping force is the clamping adjustment value of 120N multiplied by the first correction coefficient 1.2, i.e., 120 × 1.2 = 144N. This precise adjustment of the clamping force ensures that the core sample is in the optimal clamping state during cutting, guaranteeing cutting accuracy.

[0036] In some embodiments of this application, when correcting the clamping adjustment value based on the contact surface image to obtain the final clamping force value, the following steps are included: When deformation occurs, the deformation area is obtained, a second correction coefficient is determined based on the deformation area, and the clamping adjustment value is corrected using the second correction coefficient. The deformation area is inversely proportional to the second correction coefficient, and the value range of the second correction coefficient is 1 > 0.5; and the final value of the clamping force is the product of the clamping adjustment value and the second correction coefficient.

[0037] Understandably, this invention, when a core sample deforms, obtains the deformed area and, based on the inverse relationship between the deformed area and a second correction coefficient (with a value range of 1 > second correction coefficient > 0.5), scientifically and rationally corrects the clamping adjustment value. Because a larger deformed area results in a smaller second correction coefficient, it means that the clamping force is reduced accordingly based on the degree of deformation, preventing further damage to the deformed core sample due to excessive clamping force, while ensuring sufficient clamping force to maintain sample stability. The final clamping force value is obtained by multiplying the clamping adjustment value by the second correction coefficient, achieving precise calibration of the clamping force and maximizing cutting accuracy and sample quality.

[0038] Specifically, for example, during the cutting of a core sample, the clamping adjustment value has been determined to be 150N. The image acquisition device detects that the core sample has deformed, and the measured deformation area is 8 square centimeters. Based on the pre-set relationship between the deformation area and the second correction coefficient, the second correction coefficient is determined to be 0.6 (because the deformation area is inversely proportional to the second correction coefficient and is within the range of values). Therefore, the final clamping force is 150 × 0.6 = 90N, which makes the clamping force adapt to the deformation of the core sample and ensures that the cutting work proceeds smoothly.

[0039] On the other hand, see Figure 2 As shown, this application also provides a clamping adjustment system for a core sample spacing cutting device, used to apply the above-described clamping adjustment method for a core sample spacing cutting device, including: An image acquisition device is installed on the side wall of the clamping head. The image acquisition device is used to acquire images of the contact surface between the clamping head and the core sample in real time. The acquisition module is used to acquire the hardness and volume data of the current core sample, as well as the target volume of the target core sample, and to preliminarily determine the clamping force based on the hardness and volume data. The adjustment module is used to determine whether to adjust the clamping force based on the volume data and the target volume. If it is determined that adjustment is needed, the clamping force is adjusted to obtain a clamping adjustment value. The correction module is used to determine whether the clamping adjustment value needs to be corrected based on the contact surface image. If it is determined that correction is needed, the clamping adjustment value is corrected based on the contact surface image to obtain the final clamping force value.

[0040] Understandably, the image acquisition device can acquire real-time images of the contact surface between the clamping head and the core sample, providing a direct basis for accurately assessing the clamping condition, helping to detect anomalies promptly, and ensuring the accuracy and safety of the cutting. The acquisition module can obtain hardness and volume data of the core sample and initially determine the clamping force, making targeted adjustments based on sample characteristics to avoid sample damage or cutting deviations caused by improper clamping force. The adjustment module determines whether to adjust the clamping force based on the volume data and target volume, making the clamping force adaptable to different cutting needs and improving the flexibility and adaptability of the cutting. The correction module corrects the clamping adjustment value based on the contact surface image, further optimizing the clamping force, and finally obtaining a precise final clamping force value. The entire system, with its multiple modules working together, comprehensively and precisely adjusts the clamping force, ensuring that the core sample cutting work is carried out efficiently, accurately, and stably, providing strong support for related scientific research and production work.
