[0036] The platform 112 serves as the foundation of the fixed platform 106, and it provides a stable platform for carrying and supporting other components. The support block 113 is fixed on the platform 112 to enhance the stability of the platform 112 and provide additional support for the sliding track of the fixed block 114. The fixed block 114 is slidably set on the platform 112, and can slide on the platform 112 through the push of the fixed cylinder 115 to achieve the fixation or release of the BAR bar. The output end of the fixed cylinder 115 is connected to the fixed block 114 to control the movement of the fixed block 114 to ensure that the BAR bar remains stable and motionless during the detection process.

[0037] The fixing platform 106 further includes a return spring 116 , and the return spring 116 is disposed between the fixing block 114 and the fixing cylinder 115 .

[0038] The return spring 116 is disposed between the fixed block 114 and the fixed cylinder 115. When the cylinder retracts, the spring 130 provides elastic force to help the fixed block 114 quickly return to the initial position to prepare for the next fixing action.

[0039] The transverse moving member 107 includes a support rod 117, a sliding block 118, a driving motor 119 and a screw 120. The support rod 117 is fixed on the platform 112.

The sliding block 118 is slidably connected to the support rod 117, and is driven by the drive motor 119 through the screw 120 to achieve translation in the X-axis direction. The output end of the drive motor 119 is fixedly connected to the screw 120, providing power to rotate the screw 120, thereby driving the sliding block 118 to move along the support rod 117. The screw 120 is threadedly connected to the sliding block 118, and the rotational motion of the motor is converted into linear motion through rotation.

[0041] The longitudinal moving member 108 includes a driving cylinder 121 and a mounting block 122 . The driving cylinder 121 is fixed on the sliding block 118 , and the mounting block 122 is fixedly connected to the output end of the driving cylinder 121 .

[0042] The driving cylinder 121 is fixed on the sliding block 118, and controls the movement of the mounting block 122 in the Y-axis direction to achieve longitudinal positioning. The mounting block 122 is fixedly connected to the output end of the driving cylinder 121, and carries the simulation bar 109 and other related components.

[0043] The simulation bar 109 includes a support bar 123, a sliding bar 124 and a clamp 125. The support bar 123 is fixed on the mounting block 122. The sliding bar 124 is slidably connected to the support bar 123 and is located on one side of the support bar 123. The clamp 125 is arranged between the support bar 123 and the sliding bar 124.

[0044] The support bar 123 is fixed on the mounting block 122 to provide support for the simulation bar 109 and to serve as a guide for the sliding bar 124. The sliding bar 124 is slidably connected to the support bar 123 and can slide on the support bar 123 to change the spacing, so that BAR bars of different widths can be simulated. The clamp 125 is used to fix the relative distance between the support bar 123 and the sliding bar 124.

[0045] The simulation bar 109 further includes an adjusting screw 126 , which is rotatably connected to the support bar 123 and is threadedly connected to the sliding bar 124 .

[0046] The adjusting screw 126 is rotatably connected to the supporting bar 123 and is threadedly connected to the sliding bar 124 to fine-tune the position of the sliding bar 124 to achieve precise positioning.

[0047] The simulation bar 109 further includes a ruler 127 , and the ruler 127 is disposed on one side of the sliding bar 124 .

[0050] Two clamping blocks 128 are respectively slidably arranged on one side of the first rod of the support bar 123 and the second rod of the sliding bar 124, and are used to simulate the clamping action of the clamp. The set screw is threadedly connected to the clamping block 128, and is used to adjust the position of the clamping block 128 to ensure the stability of the simulated bar 109 when it contacts the BAR bar clamp. The spring 130 is arranged between the two clamping blocks 128 to provide elastic force to ensure that the clamping block 128 can smoothly fit the simulated bar 109 and improve the clamping effect. The guide rod 131 is arranged between the two clamping blocks 128 to limit the moving direction of the clamping block 128 and prevent the clamping block 128 from offsetting during the clamping process.

[0051] The judgment component 103 includes a data acquisition unit 132, a data processing unit 133 and a judgment unit 134. The data acquisition unit 132 is used to acquire sensor data; the data processing unit 133 is used to convert the sensor data into detection data; and the judgment unit 134 is used to compare the detection data with the standard data range.

[0052] The data acquisition unit 132 reads the original signals from various sensors (such as the pressure sensor 110 and the distance sensor 111) in the detection component 102. These signals are usually in the form of electrical signals, representing the physical state parameters of the BAR bar clamp when working, such as the magnitude of the clamping force and the distance between the clamp and the analog bar 109. The function of the data processing unit 133 is to convert and process the original signals obtained from the data acquisition unit 132, and convert them into digital detection data that can be directly used for analysis and comparison. This process may involve steps such as signal amplification, filtering, analog-to-digital conversion (A / D conversion) and data formatting. For example, the original voltage signal needs to be converted into a specific numerical value, such as Newton (N) to represent pressure, or millimeters (mm) to represent distance. In addition, the data processing unit 133 also removes noise to ensure the accuracy and reliability of the data. The judgment unit 134 is a key part of the judgment component 103. It receives the processed detection data and compares it with a preset standard data range. These standard data ranges are formulated based on the design specifications and performance requirements of the BAR bar clamp to ensure that the working state of the clamp meets the established quality standards. The judgment unit 134 checks whether the detection data falls within the allowed range through algorithm calculation, so as to judge whether the working state of the clamp is normal.

[0053] The algorithm of the judgment unit 134 may include a simple threshold comparison, that is, if the detection data exceeds or falls below a certain threshold, it is judged to be abnormal; more complex statistical analysis methods, such as mean value, standard deviation, etc., may also be used to evaluate the fluctuation of the data and determine whether there is a trend change or abnormal pattern.

[0054] In addition, the judgment unit 134 can also use machine learning technology to train models based on historical data to identify more subtle performance changes or potential precursors to failures, thereby improving the accuracy and predictability of judgments.

[0055] In the whole process, the data acquisition unit 132 first captures the original signal of the sensor, and then the data processing unit 133 processes and transforms these signals to generate clear detection data. Finally, the judgment unit 134 compares these detection data with the standard data range to evaluate the working status of the BAR bar clamp. If necessary, it will trigger the corresponding warning or control signal to notify the operator or control system to take appropriate actions to maintain the normal operation of the equipment and production quality.

[0056] Second embodiment

[0057] See also Figure 8 The present invention provides an intelligent detection method for a BAR bar fixture, comprising:

[0058] S201: placing the BAR bar fixture to be tested on the fixing table 106 and fixing it;

[0059] In the first step of the testing process, the staff needs to place the BAR bar fixture to be tested on a specially designed fixing table 106. The fixing table 106 is usually equipped with a precise positioning device and a stable clamping mechanism to ensure that the BAR bar fixture remains absolutely still during the testing process to avoid any slight displacement that affects the accuracy and repeatability of the test. After the fixation is completed, the fixture is firmly locked in the predetermined position, providing a stable foundation for the subsequent testing steps.

[0060] S202: Start the transverse moving member 107 and the longitudinal moving member 108 to drive the simulation bar 109 into the BAR bar fixture;

[0061] Next, the system automatically starts the lateral moving part 107 and the longitudinal moving part 108, which work together to accurately control the position of the simulated bar 109 so that it can enter the BAR bar fixture accurately. This process relies on high-precision servo motors and linear guides to ensure that the simulated bar 109 can achieve sub-millimeter positioning accuracy in both the lateral and longitudinal directions. The shape and size of the simulated bar 109 strictly simulate the characteristics of the actual workpiece in order to truly reflect the working state of the BAR bar fixture in the actual production environment.

[0062] S203 clamps the simulation bar 109 through the BAR bar furniture, and collects clamping force data and clamping distance data through the pressure sensor 110 and the distance sensor 111;

[0063] When the simulation bar 109 is fully in place, the BAR bar clamp will perform a clamping action, and the simulation bar 109 will be tightly clamped. At this time, the pressure sensor 110 and the distance sensor 111 embedded in the clamp start to work, monitoring and recording the clamping force data and the clamping distance data in real time. The pressure sensor 110 can measure the magnitude of the force applied by the clamp on the simulation bar 109, while the distance sensor 111 is used to measure the distance between the two contact surfaces of the clamp. These two sets of data are crucial for evaluating the performance of the clamp.

[0064] S204: judging the working state of the BAR bar clamp through the judging component 103 based on the clamping force data and the clamping distance data.

[0065] In the last step, the system passes the collected clamping force data and clamping spacing data to the judgment component 103 for analysis. The judgment component 103 usually contains advanced data analysis algorithms, which can quickly compare these data with the preset standard data range to evaluate whether the working state of the BAR bar clamp meets the design requirements. Once an abnormality is found, the system will immediately issue an alarm to remind the operator to perform maintenance or replacement in time, thereby avoiding possible failures and delays on the production line.

[0066] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
