[0102] In a specific embodiment 1 of the present invention, the design and production process includes:

[0103] 1. Before work, according to the size of the torque shaft axle to be monitored, set the position of the second y-direction sliding base, so as to determine the distance between the second y-direction sliding base and the first y-direction sliding base, that is, the distance between the side positioning mechanisms at both ends, and the distance between the second detection mechanism and the first detection mechanism. This position is the initial position of each detection work;

[0104] 2. Place the torsion shaft axle on the first y-direction sliding base and the second y-direction sliding base at the same time, and make the inner side of the torsion shaft axle contact the clamping base of the workpiece clamping mechanism, and press the start button on the control panel;

[0105] 3. The side positioning mechanism on the second y-direction sliding base is driven by the x-direction driving structure to drive the side positioning mechanism to push the torsion shaft axle as a whole to the set position;

[0106] 4. The left and right sets of workpiece clamping mechanisms drive the pressing plates downward through their own gas-liquid booster cylinders, and the pressing plates contact the torsion shaft bridge tube and clamp the torsion shaft axle;

[0107] 5. When the first Y-axis sliding base and the second Y-axis sliding base transport the torsion shaft axle to the center of the V-shaped inner cavity of the torsion half-shaft assembly and the first pressing block and the second pressing block, the first detection mechanism and the second detection mechanism drive the first pressing block and the second pressing block to press down for detection;

[0108] 6. The first detection mechanism and the second detection mechanism act simultaneously, and both ends detect simultaneously. The pressure and displacement are recorded by the first pressure sensor, the second pressure sensor, the first displacement sensor, and the second displacement sensor. The displacement detection of the first displacement sensor works according to the instruction of the first pressure sensor, and the second displacement sensor works according to the instruction of the second pressure sensor. The counting starts when the pressure is generated, and the counting ends when the set pressure is reached.

[0109] 7. Scan the code with a barcode scanner and upload the data to the database, one code for each item, making it easy to query the results;

[0110] 8. The workpiece clamping mechanism releases the workpiece;

[0111] 9. The first y-axis sliding base and the second y-axis sliding base transport the workpiece to the origin, remove the torque shaft axle, and complete one test. The next test repeats this process, and the cycle repeats;

[0112] The detection process is fully automatic, and data is automatically collected and uploaded to avoid human intervention affecting the test results.

[0113] This application also has the following advantages:

[0114] 1. The movement of the first y-direction sliding base, the second y-direction sliding base, and the third y-direction guide rail are all controlled by high-precision servo motors, and the second y-direction sliding base and the first y-direction sliding base return to the origin after each test is completed, which can eliminate the error accumulation caused by multiple times during the test process and ensure the accuracy of each test;

[0115] 2. The first x-guide rail, the second x-guide rail, the first y-guide rail, the second y-guide rail and the third y-guide rail all adopt linear guide rails and central lead screw structures, which have the characteristics of high strength, low friction, high positioning accuracy and high speed;

[0116] 3. The first and second detection mechanisms use servo electric cylinders to provide pressure, which has the characteristics of controlling pressure and calculating displacement. At the same time, they are equipped with pressure sensors and displacement sensors for double protection, ensuring the data accuracy of the detection results;

[0117] 4. During the pressing process, the torsion shaft axle rotates with the central axis of the torsion shaft bridge tube as the axis of rotation, and the torsion half-shaft assembly performs circular motion; the detection equipment in the prior art fixes the bridge tube, and the pressure head can only move up and down, which affects the detection accuracy; when the pressure head of the device in the present application presses down, the first y-direction sliding base and the second y-direction sliding base are in a free state in the y-axis direction, so that the torsion half-shaft axle can move forward and backward following the pressing of the first pressure head and the second pressure head, thereby increasing the detection accuracy and stability;

[0118] 5. The first displacement sensor and the second displacement sensor work according to the instructions of the first pressure sensor and the second pressure sensor during detection. They start counting when pressure is generated and end counting when pressure is reached. The accuracy of the displacement sensor is 0.005mm, and the measurement of displacement under load is more accurate.

[0119] 6. The side positioning mechanism is an automatic positioning device driven by a servo motor, with high positioning accuracy, reducing the labor intensity of workers;

[0120] 7. The workpiece clamping mechanism adopts a gas-liquid booster cylinder for clamping, which has the characteristics of high pressure, simple structure and easy installation;

[0121] 8. The first detection mechanism and the second detection mechanism simultaneously detect the torsion shaft rubber rods at both ends of the torsion shaft, and the data are synchronously measured and calculated respectively, which effectively improves the work efficiency, and at the same time eliminates the need for secondary positioning and reduces errors;

[0122] 9. This equipment adopts PLC control system. When changing different models of products, you only need to add or call out the matching solution to test the new products. There is no need to adjust the equipment manually. The positioning is accurate, convenient and fast.

[0123] 10. The all-in-one machine in this application has the characteristics of wide application range, simple operation, low labor intensity, and diverse detection methods. The production efficiency of this machine is increased from the original 30 pieces / day to 120 pieces / day, which matches the efficiency of the previous assembly process and synchronizes online monitoring, reducing costs while improving efficiency.

[0125] In a third specific embodiment of the present invention, the first servo electric cylinder is replaced by an oil cylinder.

[0126] In a fourth specific embodiment of the present invention, the gas-liquid booster cylinder is replaced by an oil cylinder.

[0127] In a fifth specific embodiment of the present invention, the first x-guide rail, the second x-guide rail, the first y-guide rail seat, the second y-guide rail seat, and the third y-guide rail seat are all linear rails.
