[0011] See also Figure 1 , Figure 1 The present invention is a flow chart of a method for adjusting the rapid moving speed according to the load size in accordance with an embodiment of the present invention. The method is applied to a CNC machine tool, which includes a linear rail, a slider slidably arranged on the linear rail, and a workbench fixed on the slider, wherein a sensor is arranged between the workbench and the slider. The method includes: S101: In response to a workpiece to be processed being placed on a workbench, feedback data collected by a sensor is obtained; wherein the feedback data is related to the weight of the workpiece to be processed.

[0012] Specifically, when a workpiece to be processed is placed on a workbench, feedback data related to the weight of the workpiece to be processed collected by a sensor disposed between the workbench and the slider is obtained.

[0013] In one application, when a workpiece to be processed is placed on a workbench, a sensor arranged between the workbench and the slider collects feedback data related to the weight of the workpiece to be processed, and the CNC machine tool sends a data acquisition instruction to the sensor, and the sensor sends the feedback data to the CNC machine tool according to the data acquisition instruction.

[0014] In another application mode, when a workpiece to be processed is placed on a workbench, a sensor arranged between the workbench and the slider collects feedback data related to the weight of the workpiece to be processed, and sends the feedback data to a data box, and a CNC machine tool obtains the feedback data after analysis and processing by the data box.

[0015] In one application scenario, the sensor is a resistance strain gauge. In other application scenarios, the sensor is a semiconductor strain gauge or other device that can sense external pressure and change its own resistance. This application does not make specific restrictions here.

[0016] Optionally, the present application does not impose any specific limitation on the number of workpieces to be processed.

[0017] S102: Based on the feedback data, determine the speed matching value corresponding to the linear track, and use the speed matching value to adjust the moving speed of the linear track.

[0018] Specifically, a speed matching value corresponding to the linear track is determined based on the acquired feedback data, and the moving speed of the linear track is adjusted according to the speed matching value.

[0019] In one application, the weight of the workpiece to be processed is determined based on the obtained feedback data, multiple matching reference speed values ​​are obtained based on the workpiece weight, the median of the multiple reference speed values ​​is taken as the speed matching value corresponding to the linear rail, and the moving speed of the linear rail is adjusted according to the speed matching value.

[0020] In another application method, the weight of the workpiece to be processed is determined based on the obtained feedback data, and the corresponding reference weight interval is determined based on the workpiece weight, wherein each reference weight interval corresponds to a speed matching value corresponding to a linear rail, and the moving speed of the linear rail is adjusted according to the speed matching value.

[0021] In some application scenarios, a CNC machine tool has a corresponding speed lookup table, and the speed lookup table stores the relationship between the working weight and the reference speed value.

[0022] In the above scheme, when the workpiece to be processed is placed on the workbench, feedback data related to the weight of the workpiece to be processed is collected by the sensor arranged between the workbench and the slider, and the speed matching value corresponding to the linear rail is determined based on the obtained feedback data. The moving speed of the linear rail is adjusted according to the speed matching value. By detecting the change of the load-bearing weight of the workbench, the moving speed of the linear rail is automatically adjusted. On the one hand, it can meet the needs of rapid processing of light-weight workpieces, and on the other hand, it can meet the needs of stable processing of heavy-weight workpieces, thereby improving the processing efficiency of the equipment and reducing abnormal failures of the equipment.

[0023] In one embodiment, the sensor includes a resistance strain gauge. In step S101, in response to the workpiece to be processed being placed on the workbench, obtaining feedback data collected by the sensor specifically includes: in response to the workpiece to be processed being placed on the workbench, obtaining the resistance change of the resistance strain gauge, and determining the resistance change as feedback data.

[0024] Specifically, when the workpiece to be processed is placed on the workbench, the resistance strain gauge installed between the workbench and the slider will produce different strains due to the external pressure, thereby causing the internal resistance of the resistance strain gauge to change, and the resistance change is obtained. The resistance change is determined as feedback data. By using the resistance change of the resistance strain gauge as feedback data, the load-bearing changes of the workbench can be obtained in real time and accurately.

[0025] In one implementation scenario, the feedback data of the resistance strain gauge is connected to a data box and transmitted to the CNC machine tool through the data box.

[0026] In one embodiment, see Figure 2 , Figure 2 yes Figure 1 Step S102 in the figure corresponds to a flowchart of an implementation method. Step S102 specifically includes: S201: Determine the weight of the workpiece to be processed based on the feedback data.

[0027] Specifically, based on the acquired feedback data, the weight of the workpiece to be processed is determined.

[0028] S202: Obtain a reference speed value that matches the weight of the workpiece, and determine a speed matching value corresponding to the linear track based on the reference speed value.

[0029] Specifically, a reference speed value matching the weight of the workpiece to be processed is acquired, and a speed matching value corresponding to the linear track is determined based on the reference speed value.

[0030] Optionally, the CNC machine tool has a corresponding speed query table, in which the relationship between the working weight and the reference speed value is stored, and the corresponding reference speed value can be obtained by querying the speed query table.

[0031] In one implementation scenario, there is a conversion relationship between the feedback data and the workpiece weight, and the workpiece weight is obtained based on the conversion relationship. There is a speed query table between the workpiece weight and the reference speed value, and the reference speed value is obtained by querying the speed query table.

[0032] Specifically, by analyzing the feedback data and the workpiece weight, a conversion relationship between the two can be obtained. Therefore, when the CNC machine tool obtains the feedback data, the corresponding workpiece weight of the workpiece to be processed can be obtained according to the conversion relationship. A speed query table is pre-configured between the workpiece weight and the reference speed value. The speed query table is used to query and obtain the reference speed value. Therefore, when the workpiece to be processed is placed on the workbench, the CNC machine tool can quickly obtain the reference speed value according to the feedback data.

[0033] In one embodiment, before step S202, the method further includes: acquiring a workpiece category of the workpiece to be processed, wherein the workpiece category is at least related to the shape of the workpiece to be processed.

[0034] Specifically, before obtaining the reference speed value matching the weight of the workpiece, the workpiece category of the workpiece to be processed is also obtained, and the workpiece category is at least related to the shape of the workpiece to be processed.

[0035] Optionally, the workpiece category may also be related to factors such as the material and size of the workpiece to be processed, and this application does not impose any specific limitation here.

[0036] In one implementation scenario, step S202 specifically includes: obtaining a reference speed value that matches the weight of the workpiece, and determining a speed matching value corresponding to the linear track based on the reference speed value, the weight of the workpiece, and the type of the workpiece.

[0037] Specifically, a reference speed value that matches the weight of the workpiece is obtained, and the speed matching value corresponding to the linear rail is determined based on the reference speed value, the weight of the workpiece to be processed and the type of the workpiece. Different types of workpieces, such as shafts, disks and plates, have different requirements for processing trajectories and processing speeds. Therefore, the optimal speed matching value corresponding to the linear rail can be determined by comprehensively considering the workpiece weight, workpiece type and reference speed value, thereby ensuring the optimal balance between stability, precision and efficiency during CNC machine tool processing.

[0038] It can be understood that, for some workpieces to be processed corresponding to workpiece categories that have certain requirements on processing accuracy, the speed matching value corresponding to the linear track may be smaller than the reference speed value.

[0039] In a specific implementation scenario, there are three types of workpieces to be processed, namely shaft workpieces, disk workpieces and plate workpieces, and the workpiece weights corresponding to these three types of workpieces to be processed are the same, so their reference speed values ​​are the same. Generally speaking, shaft workpieces have higher requirements for dimensional accuracy than the other two types of workpieces. Therefore, the speed matching value corresponding to shaft workpieces is the smallest among the three workpieces. Disk workpieces have slightly lower requirements for dimensional accuracy than shaft workpieces. Therefore, the speed matching value corresponding to disk workpieces is greater than the speed matching value corresponding to shaft workpieces. Plate workpieces have slightly lower requirements for dimensional accuracy than disk workpieces. Therefore, the speed matching value corresponding to plate workpieces is greater than the speed matching value corresponding to disk workpieces. That is, the higher the processing accuracy corresponding to the workpiece category, the smaller the corresponding speed matching value.

[0040] In an application scenario, a reference speed value that matches the weight of a workpiece is obtained, and based on the reference speed value, the weight of the workpiece and the workpiece category, a speed matching value corresponding to the linear track is determined. Specifically, the following steps are performed: obtaining a reference speed value that matches the weight of the workpiece, constructing a prompt text based on the workpiece weight and its matching reference speed value and the workpiece category, inputting the prompt text into an intelligent analysis model, and obtaining a speed matching value corresponding to the linear track output by the intelligent analysis model.

[0041] Specifically, the intelligent analysis model is obtained after fine-tuning using example samples. The example samples include example prompt samples matched by example workpieces of different weights or categories, and example speeds of the linear rails when the example workpieces are set on the workbench. After obtaining the reference speed value that matches the working weight, a prompt text is constructed based on the workpiece weight and its matching reference speed value and the workpiece category. The prompt text is input into the trained intelligent analysis model to obtain the speed matching value corresponding to the linear rail output by the intelligent analysis model. Through the trained intelligent analysis model, a comprehensive analysis is performed based on the workpiece weight of the workpiece to be processed and its matching reference speed value and the workpiece category, and the speed matching value corresponding to the workpiece to be processed can be quickly obtained, thereby improving the processing efficiency of the CNC machine tool.

[0042] Optionally, the intelligent analysis model is a large language model, which may include but is not limited to deep neural networks (DNNs), convolutional neural networks (CNNs), recurrent neural networks (RNNs), long short-term memory networks (LSTM), and generative pre-trained Transformer models, etc. No specific restrictions are made on the specific structure and deployment of the large language model.

[0043] In another application scenario, a reference speed value that matches the weight of the workpiece is obtained, and based on the reference speed value, the weight of the workpiece and the type of the workpiece, a speed matching value corresponding to the linear rail is determined. Specifically, the method includes: obtaining a reference speed value that matches the weight of the workpiece, inputting the weight of the workpiece and the type of the workpiece into a speed configuration model, obtaining a speed configuration value output by the speed matching model, and determining the speed matching value corresponding to the linear rail based on the reference speed value and the speed configuration value.

[0044] Specifically, the speed matching model is trained using training samples, and the training samples include training speed values ​​of the linear rail when training workpieces of different weights or categories are set on the workbench. After obtaining the reference speed value that matches the weight of the workpiece, the weight and category of the workpiece to be processed are input into the trained speed configuration model to obtain the speed configuration value output by the speed matching model. Based on the reference speed value and the speed configuration value, the speed matching value corresponding to the linear rail is jointly determined. Through the trained speed configuration model, the appropriate speed configuration value can be quickly obtained according to the weight and category of the workpiece, and combined with the reference speed value analysis, the optimal speed matching value corresponding to the linear rail can be obtained, thereby improving the processing efficiency of the CNC machine tool.

[0045] Optionally, based on the reference speed value and the speed configuration value, there are many ways to jointly determine the speed matching value corresponding to the line track. The reference speed value and the speed configuration value can be compared, and the larger value between the two can be used as the speed matching value corresponding to the line track. Alternatively, the average value of the reference speed value and the speed configuration value can be calculated as the speed matching value corresponding to the line track, depending on the actual situation, and this application does not make any specific restrictions here.

[0046] In a specific implementation scenario, there are two types of workpieces to be processed, namely shaft workpieces and disk workpieces, and the workpiece weights corresponding to these two types of workpieces to be processed are the same. Since the requirements for dimensional accuracy of shaft workpieces are higher than those for disk workpieces, after obtaining the reference speed value and the speed configuration value, the reference speed value and the speed configuration value are compared, and the larger value between the two is used as the speed matching value corresponding to the disk workpiece, and the smaller value between the two is used as the speed matching value corresponding to the shaft workpiece. For example, when the reference speed value is greater than the speed configuration value, the reference speed value is used as the speed matching value for the disk workpiece, and the speed configuration value is used as the speed matching value for the shaft workpiece.

[0047] S203: Adjust the moving speed of the linear rail to a speed matching value.

[0048] Specifically, the moving speed of the linear rail is adjusted to a corresponding speed matching value.

[0049] In one implementation scenario, after step S201, the method further includes: in response to the weight of the workpiece to be processed exceeding a preset weight threshold, generating a prompt message; wherein the prompt message is used to indicate that a workbench failure has occurred.

[0050] Specifically, when the working weight of the workpiece to be processed exceeds a preset weight threshold, a prompt message is generated to indicate that a workbench failure has occurred. The prompt message can quickly remind the user that the workbench has failed and needs timely maintenance, thereby ensuring the processing efficiency of the CNC machine tool and protecting the equipment safety of the CNC machine tool.
