[0006] The present invention further illustrates that the intelligent simulation system also includes a vibration frequency identification module, a number identification module, a looseness prediction module and a simulation prediction module; the vibration frequency identification module, the number identification module, the looseness prediction module and the simulation prediction module are electrically connected to each other, the vibration frequency identification module is used to identify the vibration frequency when the spline module is running, the number identification module is used to identify the number of times that the motor two rotates alternately in the forward and reverse direction, the looseness prediction module is used to predict the looseness between the reinforcement block, the belt two and the pad according to the number of times that the motor two rotates alternately in the forward and reverse direction, and the simulation prediction module is used to simulate the time when the reinforcement block, the belt two and the pad become loose after the spline module is running, so as to determine the maintenance time.

[0007] The present invention further illustrates that the operation steps of the intelligent simulation system include: step S1, the spline module is running, and the intelligent simulation system is running; step S2, by identifying the number of rotations of the second motor, the moving distance of the slider is identified, and then the actual moving distance of the slider is sensed by the sensing bar, and finally by comparing the moving distance of the slider identified by the distance measurement module and the actual moving distance of the slider, when an error occurs between the two, an alarm is issued through the alarm module; step S3, by identifying the vibration frequency when the spline module is running, the time when the reinforcement block, the second belt and the cushion block become loose is predicted, thereby measuring the maintenance time; step S4 , improve the accuracy of maintenance time once according to the number of times Motor 2 rotates clockwise and counterclockwise alternately, and go to step S5 when the number of times Motor 2 rotates clockwise and counterclockwise alternately exceeds the system set value, otherwise go to step S7; Step S5, the looseness between the reinforcement block, belt 2 and the pad is improved, and the time of increased looseness is measured, and the accuracy of maintenance time is improved twice; Step S6, the overall temperature of the spline module increases, and belt 2 produces thermal expansion, thereby optimizing the looseness between the reinforcement block, belt 2 and the pad, and improving the accuracy of maintenance time three times; Step S7, the spline module stops running, and the intelligent simulation system stops running.

[0008] The present invention further illustrates that in step S3, the maintenance time of the spline module is measured according to the vibration frequency of the spline module during operation: , The time required for maintenance after the spline module is running. The maximum time required for maintenance after the spline module is running. is the vibration frequency of the spline module after operation. It is the highest vibration frequency of the spline module after operation; that is, the higher the vibration frequency of the spline module after operation, the longer the maintenance time required after operation.

[0009] The present invention further illustrates that in step S4, the spline module maintenance time is improved once: ,Right now The alternating forward and reverse rotation of the second motor causes the looseness between the reinforcement block, the second belt and the pad to increase, thereby increasing the time required for maintenance of the spline module after operation. The time required for maintenance of the spline module after the precision is improved. is the number of times the motor rotates alternately in the forward and reverse directions. It is the maximum number of times that the motor 2 rotates alternately in the forward and reverse directions; that is, the higher the number of times that the motor 2 rotates alternately in the forward and reverse directions, the greater the looseness between the reinforcement block, the belt 2 and the cushion block, and thus the longer the maintenance time of the spline module is extended.

[0010] The present invention further illustrates that in the steps S4 and S5, the maintenance time of the spline module is improved twice in accuracy: when hour, The number of times the motor 2 rotates alternately in the forward and reverse directions is set for the system: , The time required for maintenance of the spline module after the secondary precision improvement. The interaction force between the reinforcement block, belt 2 and pad causes the looseness. The maximum looseness is generated by the interaction force between the reinforcement block, belt 2 and the pad; that is, when the number of forward and reverse alternations of motor 2 exceeds the system setting value, the interaction force between the reinforcement block, belt 2 and the pad increases, and the looseness changes significantly, thereby further optimizing the maintenance time of the spline module; when hour: .

[0011] The present invention further illustrates that in the steps S4, S5 and S6, the maintenance time of the spline module is improved three times: when hour: , To optimize the looseness between the reinforcement block, belt 2 and pad, , The temperature of the spline module increases as a whole after the second motor rotates alternately in the forward and reverse directions for a long time. It is the highest temperature of the spline module as a whole that increases after the second motor rotates forward and reverse for a long time; that is, when the number of forward and reverse rotations of the second motor exceeds the system setting value, the temperature generated by the operation of the spline module increases, the second belt generates thermal expansion, and the reinforcement block, the second belt and the cushion block fit more closely, thereby reducing the looseness between the reinforcement block, the second belt and the cushion block; when hour: .

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the spline module adopted by the present invention enables the spline shaft to rotate and move left and right, and at the same time, the connecting block drives the slider to slide left and right on the slide rail, providing a guiding effect, so that the left and right movement of the spline shaft is more stable, and the connecting block drives the guide piece to move back and forth in the guide groove, and the movement stability of the spline shaft is higher. In the process of the left and right movement of the spline shaft, the sensing bar senses the actual movement distance of the slider through the distance sensing module, thereby judging the actual left and right movement distance of the spline shaft. At the same time, the second motor rotates clockwise and counterclockwise alternately, and the movement distance of the slider is measured according to the number of rotations of the second motor. Then, the two data are compared through the alarm module. When the two data are not equal, an alarm is issued, and the moving position accuracy becomes poor. At this time, it indicates that there is looseness between the second belt and the connecting block, and the spline module is maintained to ensure the accuracy of the spline module operation.

[0013] By setting up an intelligent simulation system, the maintenance time of the spline module can be predicted in advance, and the spline module can be maintained before or after the time is reached to prevent it from loosening during operation and affecting the operating accuracy. This can achieve better results by making advance predictions. The maintenance time can be extended by the number of forward and reverse alternations of motor 2, and the maintenance time of the spline module can be further accurate. The interval time for a single maintenance of the spline module can be relatively lengthened, thereby improving efficiency.

[0014] When the number of times that Motor 2 rotates clockwise and counterclockwise alternately exceeds a certain value, the looseness between the reinforcement block, belt 2 and the pad increases significantly, and the increased data increases gradually, thereby further significantly shortening the maintenance time of the spline module, further accurately predicting the maintenance time, and avoiding the inaccurate prediction of the maintenance time caused by the large looseness between the reinforcement block, belt 2 and the pad at this time, and preventing the phenomenon of reduced operating accuracy due to no maintenance after a large loosening. At the same time, the increase in the overall temperature of the spline module causes belt 2 to expand thermally due to the influence of temperature, and the thermal expansion of belt 2 makes it fit more closely with the reinforcement block and the pad, and the looseness between the three is affected, thereby compensating for the looseness and reducing it, thereby relatively extending the time required for maintenance. The overall maintenance time of the spline module is extended, which can significantly increase the working time of the spline module, thereby reducing the number of maintenance times and reducing labor costs.

[0027] The surface of the slide rail 6 is provided with a sensing strip, a distance sensing module is provided inside the sensing strip, a distance measuring module is provided inside the motor 2 8, the intelligent simulation system includes an alarm module, the distance measuring module and the distance sensing module are electrically connected to the alarm module, the distance measuring module is used to identify the moving distance of the slider 5 by identifying the number of rotations of the motor 2 8, the distance sensing module is used to sense the actual moving distance of the slider 5 through the sensing strip, and the alarm module is used to compare the moving distance of the slider 5 identified by the distance measuring module with the actual moving distance of the slider 5, so as to determine whether there is an error, and to give an alarm when there is an error;

[0028] The spline module is running, and the motor 1 7 and the motor 2 8 are running at the same time. The motor 1 7 drives the pulley 71 to rotate, and the pulley 71 drives the rotating spline nut 3 to rotate through the belt 1 72, and the rotating spline nut 3 drives the spline shaft 2 to rotate. The motor 2 8 rotates alternately in the clockwise and counterclockwise direction, driving the pulley 1 81 to rotate, and the pulley 1 81 drives the pulley 2 82 to rotate through the belt 2 83, and the pulley 2 82 drives the connecting block 4 to move through the reinforcement block 41 and the pad block 42. The motor 2 8 rotates alternately in the clockwise and counterclockwise direction, so that the connecting block 4 moves left and right, and the connecting block 4 drives the spline shaft 2 to move left and right. The spline shaft 2 moves left and right while rotating, and at the same time, the connecting block 4 drives the slider 5 to slide left and right on the slide rail 6, providing a guiding effect, so that the left and right movement of the spline shaft 2 is more stable, and the connecting block 4 drives the guide piece 43 to move back and forth in the guide groove, and the movement stability of the spline shaft 2 is higher;

[0029] During the left and right movement of the spline shaft 2, the sensing bar senses the actual moving distance of the slider 5 through the distance sensing module, thereby judging the actual left and right moving distance of the spline shaft 2. At the same time, the motor 2 8 rotates alternately clockwise and counterclockwise, and the moving distance of the slider 5 is measured according to the number of revolutions of the motor 2 8. The two data are then compared through the alarm module. When the two data are not equal, an alarm is issued and the moving position accuracy becomes worse. This indicates that there is looseness between the belt 2 83 and the connecting block 4, and the spline module needs to be maintained to ensure the accuracy of the spline module operation.

[0030] The intelligent simulation system also includes a vibration frequency recognition module, a frequency recognition module, a looseness prediction module and a simulation prediction module;

[0031] The vibration frequency identification module, the number identification module, the looseness prediction module and the simulation prediction module are electrically connected to each other. The vibration frequency identification module is used to identify the vibration frequency when the spline module is running. The number identification module is used to identify the number of times that the motor 2 8 rotates alternately in the forward and reverse directions. The looseness prediction module is used to predict the looseness between the reinforcement block 41, the belt 2 83 and the pad 42 according to the number of times that the motor 2 8 rotates alternately in the forward and reverse directions. The simulation prediction module is used to simulate the time when the reinforcement block 41, the belt 2 83 and the pad 42 become loose after the spline module is running, so as to determine the maintenance time.

[0032] The operation steps of the intelligent simulation system include:

[0033] Step S1, the spline module runs, and the intelligent simulation system runs;

[0034] Step S2, identifying the movement distance of the slider 5 by identifying the number of rotations of the motor 2 8, then sensing the actual movement distance of the slider 5 through the sensing bar, and finally comparing the movement distance of the slider 5 identified by the distance measurement module with the actual movement distance of the slider 5, and when there is an error between the two, an alarm is issued through the alarm module;

[0035] Step S3, predicting the time when the reinforcement block 41, the second belt 83 and the cushion block 42 become loose by identifying the vibration frequency of the spline module during operation, thereby measuring the maintenance time;

[0036] Step S4, improve the accuracy of the maintenance time according to the number of times the motor 2 8 rotates alternately in the forward and reverse directions. When the number of times the motor 2 8 rotates alternately in the forward and reverse directions exceeds the system setting value, enter step S5, otherwise enter step S7;

[0037] Step S5, the looseness between the reinforcement block 41, the second belt 83 and the cushion block 42 is improved, the time of looseness increase is measured, and the maintenance time is secondarily improved in accuracy;

[0038] Step S6, the overall temperature of the spline module increases, and the belt 2 83 generates thermal expansion, thereby optimizing the looseness between the reinforcement block 41, the belt 2 83 and the cushion block 42, and improving the maintenance time three times;

[0039] Step S7: the spline module stops running, and the intelligent simulation system stops running.

[0040] In step S3, the maintenance time of the spline module is measured according to the vibration frequency of the spline module during operation:

[0041] , The time required for maintenance after the spline module is running. The maximum time required for maintenance after the spline module is running. is the vibration frequency of the spline module after operation. It is the highest vibration frequency after the spline module is running;

[0042] That is, the higher the vibration frequency of the spline module after operation, the longer it needs maintenance after operation;

[0043] When the vibration frequency of the spline module after operation is high, the vibration intensity between the reinforcement block 41, the belt 2 83 and the pad 42 is large, and the looseness between the three is large. Therefore, it is measured that the spline module needs maintenance for a longer time, and vice versa. The maintenance time of the spline module can be predicted in advance through simulation, and the spline module can be maintained before or after the time to avoid loosening during operation and affecting the operation accuracy, so as to achieve early prediction and better use effect.

[0044] In step S4, the spline module is maintained during a precision improvement:

[0045] ,Right now The alternating forward and reverse rotation of the motor 2 8 causes the looseness between the reinforcement block 41, the belt 2 83 and the cushion block 42 to increase, thereby increasing the time required for maintenance of the spline module after operation. The time required for maintenance of the spline module after the precision is improved. is the number of times the motor 28 rotates alternately in the forward and reverse directions, The maximum number of times that the motor 28 rotates alternately in the forward and reverse directions;

[0046] That is, the higher the number of times the motor 2 8 rotates alternately in the forward and reverse directions, the greater the looseness between the reinforcement block 41, the belt 2 83 and the cushion block 42, and thus the longer the maintenance time of the spline module is extended;

[0047] During the process of alternating forward and reverse rotation of motor 2 8, there is tension between the surface of belt 2 83 and the reinforcement block 41 and cushion block 42, which causes a certain amount of wear among the three, thereby further accelerating the loosening time between the reinforcement block 41, belt 2 83 and cushion block 42, thereby increasing the time required for maintenance, extending the maintenance time, further refining the maintenance time of the spline module, and relatively lengthening the interval time of a single maintenance of the spline module, thereby improving efficiency.

[0048] In step S4 and step S5, the maintenance time of the spline module is improved twice in accuracy:

[0049] when hour, The number of times the motor 28 rotates alternately in the forward and reverse directions is set for the system:

[0050] , The time required for maintenance of the spline module after the secondary precision improvement. The interaction force between the reinforcement block 41, the belt 2 83 and the cushion block 42 generates the looseness. The maximum looseness is generated by the interaction force between the reinforcement block 41, the belt 2 83 and the cushion block 42;

[0051] That is, when the number of times the motor 2 8 alternates forward and reverse directions exceeds the system setting value, the interaction force between the reinforcement block 41, the belt 2 83 and the cushion block 42 increases, and the looseness changes significantly, thereby further optimizing the maintenance time of the spline module;

[0052] when hour: ;

[0053] When the number of times that the motor 2 8 rotates alternately in the forward and reverse directions exceeds a certain value, the belt 2 83 drives the connecting block 4 to move back and forth a large number of times, thereby greatly increasing the looseness between the reinforcement block 41, the belt 2 83 and the cushion block 42, and the increased data is gradually increasing, thereby further greatly shortening the maintenance time of the spline module, further accurately predicting the maintenance time, avoiding the inaccurate maintenance time prediction caused by the large looseness between the reinforcement block 41, the belt 2 83 and the cushion block 42 at this time, and preventing the phenomenon of reduced operation accuracy due to no maintenance after a large looseness.

[0054] In step S4, step S5 and step S6, the spline module maintenance time is improved three times:

[0055] when hour: , To optimize the looseness between the reinforcement block 41, the belt 2 83 and the cushion block 42, , The temperature of the spline module increases as a whole after the motor 8 rotates alternately in the forward and reverse directions for a long time. The maximum temperature of the spline module as a whole increases after the motor 2 8 rotates alternately in the forward and reverse directions for a long time;

[0056] That is, when the number of times the motor 2 8 alternates between forward and reverse rotation exceeds the system setting value, the temperature generated by the operation of the spline module increases, the belt 2 83 generates thermal expansion, and the reinforcement block 41, the belt 2 83 and the cushion block 42 are more closely fitted, thereby reducing the looseness between the reinforcement block 41, the belt 2 83 and the cushion block 42;

[0057] when hour: ;

[0058] When the motor 2 8 rotates clockwise and counterclockwise alternately for a large number of times, the overall temperature of the spline module increases, causing the belt 2 83 to expand due to the temperature. The thermal expansion of the belt 2 83 makes it fit more closely with the reinforcement block 41 and the cushion block 42, and the looseness between the three is affected, so the looseness is compensated and reduced, thereby relatively extending the time required for maintenance. The overall maintenance time of the spline module is extended, which can greatly increase the working time of the spline module, thereby reducing the number of maintenance times and reducing labor costs.
