The terms used herein in the specification of the template are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0038] In the related technology, CNC machine tools are widely used, and guide rails are used as the reference for determining the relative positions of the main components in CNC machine tools. When the guide rails have errors, the relative positions of the components in the machine tools will be changed, the accuracy of the relative motion between the moving parts will be destroyed, and finally the machining accuracy of the processed parts will be affected. Therefore, the guide rail error of machine tools is a major error of machine tools.
[0039] Usually, the guide rails used on machine tools are mainly fixed by bolts. Due to improper selection of bolts, insufficient preload, deformation and loosening of the bearing surface, improper assembly process, and defective processing quality, the bolts are very easy to loosen and are difficult to detect under working conditions such as vibration, high and low load changes, and impact, which will lead to reduced machine tool accuracy and safety and reliability, and affect the quality of processed parts.
[0040] As shown in Figures 1 and 2, in order to solve the above-mentioned technical problems, an embodiment of the present application provides a guide rail assembly, which includes a guide rail 300, a fixing bolt 200, a base 400 and a pressure detection component 600. The number of the fixing bolts 200 is multiple, and the guide rail 300 is connected to the top of the base 400 through multiple fixing bolts 200, and the multiple fixing bolts 200 are arranged at intervals along the length direction of the guide rail 300; wherein, a plurality of detection points 500 are arranged on the top of the base 400, and each fixing bolt 200 corresponds to at least one detection point 500, and each detection point 500 is provided with a pressure detection component 600, and the pressure detection component 600 is used to detect the pressure of the guide rail 300 acting on the corresponding detection point 500.
[0041] The present application aims to solve the problems existing in the traditional fixing method of the guide rail 300, especially the problem of reduced machine tool accuracy and reduced safety and reliability caused by loosening of the fixing bolts. The present application adds a pressure detection member 600 to the guide rail assembly to monitor the clamping force and load changes of the fixing bolts in real time, so as to timely detect and solve the problem of loosening of the fixing bolts.
[0042] In this embodiment, the guide rail 300 is a linear motion component used to guide mechanical equipment (such as a machine tool) to ensure that it moves smoothly along a predetermined trajectory. The fixing bolt 200 is used to fix the guide rail 300 on the base 400 to ensure the stability and positioning accuracy of the guide rail 300. The base 400 provides a mounting plane for the guide rail 300 and is usually a part of the machine tool. The pressure detection component 600 is used to detect the pressure of the guide rail 300 acting on the base 400, thereby indirectly reflecting the clamping force of the fixing bolt 200 and the load borne by the guide rail 300. Among them, a plurality of fixing bolts 200 are arranged at intervals along the length direction of the guide rail 300 to ensure that the guide rail 300 has sufficient support and fixation throughout the entire length. A plurality of detection points 500 are arranged on the top of the base 400, and each fixing bolt 200 corresponds to at least one detection point 500 for placing the pressure detection component 600. Each detection point 500 is provided with a pressure detection member 600, and the pressure detection member 600 is used to monitor in real time the pressure of the guide rail 300 acting on the detection point 500. These pressure data can reflect the clamping force of the fixing bolt 200 and the load borne by the guide rail 300.
[0043] During the installation of the guide rail 300 , the clamping force of each fixing bolt 200 on the guide rail 300 is detected by the pressure detection member 600 to ensure that the bolt pre-tightening force is sufficient and evenly distributed.
[0044] For example, when the fixing bolt 200 is installed, the base 400 is deformed, and the clamping force of the fixing bolt 200 acting on the guide rail 300 is obtained by the pressure detection component 600, and the installation force of the fixing bolt 200 at each detection point 500 is fed back in real time. The data collected by the pressure detection components 600 at different positions are compared to see whether the force conditions of all the fixing bolts 200 on the guide rail 300 are relatively uniform. If individual fixing bolts 200 are not tightened or over-tightened, the corresponding data collected by the pressure detection component 600 will be reduced or increased accordingly, and can be adjusted in time.
[0045] During the operation of the guide rail 300, the pressure detection member 600 continuously monitors the pressure change of each detection point 500 to determine whether the fixing bolt 200 has a tendency to loosen. If the pressure at a detection point 500 is detected to drop abnormally or fluctuate beyond the normal range, it means that the corresponding fixing bolt 200 may be loose.
[0046] For example, due to the continuous movement of the moving component on the guide rail 300, the pressure (i.e., load) on different positions of the guide rail 300 changes all the time. When the moving component moves on the guide rail 300, the base 400 is deformed, and this strain force acts on the pressure detection component 600, thereby measuring the magnitude of the strain force, which is the sum of the clamping force of the fixing bolt 200 and the bearing capacity of the guide rail 300. The forces collected at the detection points 500 corresponding to different fixing bolts 200 are compared horizontally. If the dynamic fluctuation value is abnormal, it means that the state of the fixing bolt 200 has changed.
[0047] Obviously, through real-time monitoring, problems can be found before the fixing bolts are completely loosened, avoiding the reduction of machine tool accuracy and safety accidents caused by loose fixing bolts. Ensure the stability and positioning accuracy of the guide rail 300, thereby improving the quality of the processed parts. In addition, timely detection and resolution of loose fixing bolts can reduce unplanned downtime and improve production efficiency.
[0048] like Figure 1 and Figure 2 As shown, in some embodiments, the pressure detection component 600 includes a pressure sensor, and the pressure sensor is arranged at the detection point 500.
[0049] In these embodiments, the pressure sensor is used to measure the pressure of the guide rail 300 acting on the detection point 500, thereby reflecting the clamping force of the fixing bolt 200 and the load borne by the guide rail 300. It should be noted that different types of pressure sensors can be used, such as strain gauge pressure sensors, piezoresistive pressure sensors, piezoelectric pressure sensors, etc. In this application, a high-precision strain gauge pressure sensor is selected to ensure the accuracy of the measurement results.
[0050] Obviously, each detection point 500 is provided with a pressure sensor, which is usually installed in the area where the base 400 contacts the guide rail 300. During the installation process, the clamping force of each fixing bolt 200 on the guide rail 300 is detected by the pressure sensor to ensure that the pre-tightening force of the fixing bolt 200 is sufficient and evenly distributed.
[0051] Of course, a suitable pressure sensor is selected according to actual application requirements, taking into account factors such as the sensor's range, accuracy, and response speed. Also, the location and number of the detection points 500 are reasonably planned to ensure that the state of the guide rail 300 can be fully monitored.
[0052] like Figure 1 and Figure 2 As shown, in some embodiments, the multiple detection points 500 include multiple first detection points 510 , each fixing bolt 200 corresponds to multiple first detection points 510 , and the multiple first detection points 510 are arranged at intervals along the circumference of the corresponding fixing bolt 200 .
[0053] In these embodiments, each fixing bolt 200 corresponds to a plurality of first detection points 510, which means that the number of detection points 500 around each fixing bolt increases, and the force applied to the bolt can be monitored more carefully. The detection points 500 are arranged at intervals along the circumference of the fixing bolt 200, that is, distributed in the circumferential direction around the fixing bolt, rather than at only one point near the fixing bolt.
[0054] By increasing the number of the detection points 500 and changing their layout, the stress distribution around the fixing bolt 200 can be more comprehensively understood, thereby more accurately determining whether the fixing bolt 200 has a tendency to loosen.
[0055] Through preliminary simulation calculations, it is known that during the installation of the fixing bolt 200, the stress of the fixing bolt 200 on the guide rail 300 is uniformly diffused outward in an arc shape with the fixing bolt 200 as the center. That is, after the fixing bolt 200 is tightened, the installation force of each detection point 500 corresponding to the fixing bolt 200 is fed back in real time, and data is collected by the pressure sensor of the first detection point 510 at different positions to compare whether the stress conditions of all the fixing bolts 200 on the guide rail 300 are relatively uniform.
[0056] For example, in this embodiment, the number of first detection points 510 corresponding to each fixing bolt 200 is 2. Of course, in other embodiments, the number of first detection points 510 corresponding to each fixing bolt 200 is 3, 4, 5, 6, 7, 8, and so on.
[0057] In some embodiments, the first detection point 510 is 10 mm to 20 mm away from the corresponding fixing bolt.
[0058] In these embodiments, such a design is to ensure that the pressure sensor can accurately monitor the force of the fixing bolt 200 on the guide rail 300, while avoiding errors caused by too close or too far distances. That is, each first detection point 510 is 10 mm to 20 mm away from the corresponding fixing bolt, ensuring that the pressure sensor can accurately monitor the force of the fixing bolt 200 on the guide rail 300.
[0059] In addition, according to the simulation calculation results, within the range of 10-20 mm from the fixing bolt, the stress is relatively large after the fixing bolt 200 is tightened, and the fixing bolt 200 is the center of the circle.
[0060] Among them, the appropriate distance can reduce the local stress concentration caused by the bolt head, thereby obtaining more accurate pressure data.
[0061] Obviously, too close a distance may cause the measurement results to be affected by the shape of the bolt head, while too far a distance may result in the pressure data not accurately reflecting the clamping force of the bolt.
[0062] For example, in this embodiment, the distance between the first detection point 510 and the corresponding fixing bolt 200 is 10 mm. Of course, in other embodiments, the distance between the first detection point 510 and the corresponding fixing bolt 200 may also be 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, etc.
[0063] like Figure 1 and Figure 2 As shown, in some embodiments, the multiple detection points 500 include multiple second detection points 520 , each fixing bolt 200 corresponds to multiple second detection points 520 , and the multiple second detection points 520 are arranged at intervals along the width direction of the corresponding guide rail 300 .
[0064] In these embodiments, such a design enables the system to more comprehensively monitor the stress distribution around each fixing bolt 200, thereby more accurately determining whether the bolt is loose. Each fixing bolt 200 corresponds to a plurality of second detection points 520, which means that the number of detection points 500 around each bolt is further increased, and the stress of the bolt can be monitored more carefully. Among them, these detection points 500 are arranged at intervals along the width direction of the guide rail 300, that is, distributed in the width direction of the guide rail 300. By increasing the number of second detection points 520 and changing their layout, the stress distribution around the bolt can be more comprehensively understood, thereby more accurately determining whether the bolt has a tendency to loosen.
[0065] During the operation of the machine tool, the pressure on different positions of the guide rail 300 changes constantly due to the continuous movement of the moving component on the guide rail 300, and the maximum pressure can reach several tons, which is quite different from the clamping force of the fixing bolt 200. When the moving component moves on the guide rail 300, the base 400 is deformed, and this strain acts on the pressure sensor installed at the second detection point 520, so as to measure the magnitude of the force. The stress at this point is the sum of the clamping force of the fixing bolt 200 and the bearing capacity of the guide rail 300. The forces collected at each second detection point 520 of different fixing bolts 200 are compared horizontally and compared with the simulation analysis results. If the dynamic fluctuation value of the force collected at each second detection point 520 is abnormal, it means that the state of the fixing bolt 200 has changed.
[0066] For example, in this embodiment, the number of second detection points 520 corresponding to each fixing bolt 200 is 2. Of course, in other embodiments, the number of second detection points 520 corresponding to each fixing bolt 200 is 3, 4, 5, 6, 7, 8, and so on.
[0067] In some embodiments, the second detection point 520 is 20 mm to 30 mm away from the corresponding fixing bolt.
[0068] In these embodiments, the stress effect of the fixing bolt 200 on this position is reduced, the overall stress distribution is relatively uniform, and 2 to 4 strain gauge pressure sensors with a larger range are arranged in parallel within this range. Obviously, by installing the strain gauge pressure sensors within this range, the detected values can be guaranteed to be more accurate.
[0069] For example, in this embodiment, the distance between the second detection point 520 and the corresponding fixing bolt 200 is 20 mm. Of course, in other embodiments, the distance between the second detection point 520 and the corresponding fixing bolt 200 may also be 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, etc.
[0070] like Figure 3 As shown, in some embodiments, the present application further provides a method for detecting a guide rail assembly, which is applied to a guide rail assembly as in any of the above embodiments. The method for detecting a guide rail assembly comprises the following steps:
[0071] S100: Acquire operating parameters and standard parameters of the guide rail 300, wherein the operating parameters are used to characterize the real-time pressure value of the guide rail 300 acting on the detection point 500, and the standard parameters are used to characterize the standard pressure value of the guide rail 300 acting on the detection point 500;
[0072] In this embodiment, the operating parameters are used to characterize the real-time pressure value of the guide rail 300 acting on the detection point 500, which is collected in real time by the pressure sensor. The acquisition frequency of the sensor can be set, for example, once per second or adjusted as needed. The collected raw data is subjected to necessary preprocessing, such as filtering, denoising, data smoothing, etc., to improve data quality. The standard parameters are used to characterize the standard pressure value of the guide rail 300 acting on the detection point 500, which is usually set based on design requirements or empirical values. The standard pressure value can be determined based on theoretical calculations, experimental tests or industry standards.
[0073] Of course, standard parameters can also be dynamically adjusted according to actual usage to adapt to different working conditions.
[0074] S200: Compare the operating parameters with the standard parameters, and determine the target operating state corresponding to the guide rail 300 among a plurality of preset operating states based on the comparison results; wherein the plurality of preset operating states include a normal bolt preload state, a slightly loose bolt state, a moderately loose bolt state, and a severely loose bolt state.
[0075] In this embodiment, the real-time collected operating parameters are compared with the preset standard parameters to determine the tightening state of the bolt. The threshold is set according to the specific situation, for example, the threshold for the slightly loose state of the bolt is set to 90% of the standard pressure value.
[0076] According to the comparison results, the target working state corresponding to the guide rail 300 is determined in a plurality of preset working states. The preset working states include a normal state of bolt preload, a slightly loose state of bolts, a moderately loose state of bolts, and a severely loose state of bolts. If the difference between the operating parameters and the standard parameters is less than the set threshold, it is judged to be a normal state of bolt preload; if the difference is between the threshold between the slightly loose state and the moderately loose state, it is judged to be a slightly loose state of bolts; if the difference is between the threshold between the moderately loose state and the severely loose state, it is judged to be a moderately loose state of bolts; if the difference is greater than the threshold between the severely loose state and the moderately loose state, it is judged to be a severely loose state of bolts. In other words, the thresholds of different states are reasonably set to accurately distinguish different working states.
[0077] In order to ensure the installation accuracy of the guide rail 300, a plurality of detection points 500 are set on the base 400 below the guide rail 300, and a pressure sensor is installed at each detection point 500. These pressure sensors can not only monitor the pressure of the guide rail 300 on the base 400, but also reflect the clamping force of the fixing bolt 200 by monitoring the pressure changes of the plurality of detection points 500. In this way, the operating parameters can be obtained in real time during the operation of the machine tool, and compared with the standard parameters to determine the state of the guide rail 300. For example, if the pressure value of a certain detection point 500 is significantly lower than the standard value, it may indicate that the corresponding fixing bolt 200 is loose, and measures can be taken to adjust it to ensure the accuracy and safety of the machine tool.
[0078] For example, a data acquisition system is established to collect data from the pressure sensor in real time and analyze and process it. A state judgment algorithm is designed to automatically judge the state of the guide rail 300 according to the difference between the operating parameters and the standard parameters. When it is detected that the bolt is in a loose state, the corresponding alarm mechanism is triggered to remind the operator to check and maintain it.
[0079] During the installation of the guide rail 300 of the machine tool, the operator uses a torque wrench to tighten the fixing bolt 200, but the tightening accuracy is not enough and the environmental impact is large (temperature, bolt thread, impurities, bumps, etc.), resulting in a large error in the clamping force between the bolted parts. The strain gauge pressure sensor embedded in the base 400 can provide real-time feedback on the clamping force between the connecting parts. During the tightening process of the fixing bolt 200, the force collected by the strain gauge pressure sensor can be compared with the simulation results to determine whether the clamping force of the fixing bolt 200 is close to or reaches the yield strength of the bolt material.
[0080] During the use of the guide rail 300 of the machine tool, the strain gauge pressure sensor will collect the strain on the base 400 in real time, and judge whether the fixing bolt 200 of the guide rail 300 is loose by the strain change. In addition, the detection system uses deep learning and convolutional neural network to judge whether the fixing bolt 200 of the guide rail 300 is loose, and outputs a specific label to give feedback on the current situation.
[0081] In some embodiments, after determining the target working state corresponding to the guide rail 300 from among the multiple preset working states according to the comparison result, the method further includes:
[0082] According to the target working operation state corresponding to the guide rail 300, the target operation instruction corresponding to the guide rail 300 is determined from a plurality of preset operation instructions, and the operation of the guide rail 300 is controlled based on the target operation instruction.
[0083] In these embodiments, the preset operation instructions include normal operation instructions, deceleration operation instructions, stop instructions, etc. If the guide rail 300 is in a normal state of bolt pre-tightening force, the normal operation instruction is executed; if the bolt is slightly loose, the deceleration operation instruction is executed and a warning is issued; if the bolt is moderately or severely loose, the stop instruction is executed and the operator is immediately notified to check and repair.
[0084] Controlling the operation of the guide rail 300 based on the target operation instruction: According to the determined target operation instruction, the operation state of the guide rail 300 is adjusted by the control system. The control system includes a motor controller, a servo driver, etc., which are used to adjust the speed and torque of the motor according to the instruction.
