The four active pressing components 7 are used to press against the object to be measured from the side in four directions. When measuring the mechanical parameters, when force is applied to the object to be measured from top to bottom, the four active pressing components 7 can constrain from the side to avoid the object from shifting, thereby improving the measurement accuracy and stability of the entire measuring device and providing a solid foundation for subsequent data processing and analysis.

[0037] Among them, the sensor device is the core part of the measuring device, including various types of mechanical sensors. The sensor device may include a strain sensor 11 and a displacement sensor 12. The strain sensor 11 and the displacement sensor 12 are both embedded in the lower end surface of the pressure seat 5. The sensor device also includes a pressure sensor 9. The pressure sensor 9 is embedded in the upper end surface of the bracket 6. The strain sensor 11 can be used to measure the strain of the object; the pressure sensor 9 can measure the magnitude of the dynamic force; and the displacement sensor 12 can accurately measure the tiny displacement of the object.

[0038] See also Figure 2-Figure 4 As shown, four movable pressing assemblies 7 are symmetrically arranged at the four sides of the upper end surface of the supporting member, and each movable pressing assembly 7 includes a support seat 71, a fixed clamp block 72 and an adjustment structure 74. The fixed clamp block 72 is fixed to the upper end surface of the support seat 71, and movable clamp blocks 73 are provided on both sides of the fixed clamp block 72. The adjustment structure 74 is used to synchronously adjust the two movable clamp blocks 73 to deflect in opposite directions.

[0039] Among them, see Figure 4 As shown, the adjustment structure 74 includes a motor 741, and a mounting groove is provided on the upper end surface of the support seat 71. The motor 741 is installed at one end inside the mounting groove, and a first connecting shaft 742 is connected between the output end of the motor 741 and the bottom end of one of the movable clamping blocks 73, a first gear 743 is installed on the outside of the first connecting shaft 742, a fourth connecting shaft 748 is connected to the bottom end of the other movable clamping block 73, a fourth connecting shaft 748 is installed on the outside of the fourth connecting shaft 748, a second connecting shaft 744 and a third connecting shaft 746 are rotatably installed inside the mounting groove and between the first connecting shaft 742 and the fourth connecting shaft 748, a second gear 745 is installed on the outside of the second connecting shaft 744, a third gear 747 is installed on the outside of the third connecting shaft 746, and the first gear 743, the second gear 745, the third gear 747 and the fourth gear 749 are meshed in sequence.

[0040] Through the above, after the object to be tested is placed on the bracket 6, the fixing clamps 72 can be used to press the side from four directions to ensure that the object to be tested does not move sideways.

[0041] Since the sides of some objects to be measured are irregular in shape, in such a complex situation, the adjustment structure 74 demonstrates its unique adaptability advantage. The adjustment structure 74 can accurately control the movable clamps 73 on both sides of the fixed clamp 72 to perform flexible deflection movements. They can dynamically adjust their own angles and positions according to the specific contours and curvature changes of the sides of the irregular objects to be measured, so as to achieve a close fit and effective pressure against the sides of the objects. Regardless of whether it is a curved surface with an arc or a concave or convex shaped surface, the movable clamp 73 can apply a stable pressure through the control of the adjustment structure 74, thereby further enhancing the compatibility and adaptability of the entire measuring device to objects to be measured of different shapes, greatly expanding the application scope of the device in the measurement of mechanical parameters of objects in multiple fields and types, and effectively ensuring the smooth progress of the measurement work and the accuracy and reliability of the measurement results.

[0042] See also Figure 1 and Figure 5 As shown, each moving assembly corresponds to a movable pressing assembly 7 , and the moving assembly is used to drive the movable pressing assembly 7 to move closer to or away from the upper end surface of the bracket 6 .

[0043] The moving assembly includes a second hydraulic cylinder 8 installed on the upper end surface of the bracket 6, the output end of the second hydraulic cylinder 8 is connected to the support seat 71, and the upper end surface of the bracket 6 is provided with a guide groove 10, and the bottom end of the support seat 71 is connected with a guide block slidably matched with the guide groove 10. By starting the second hydraulic cylinder 8 and using the second hydraulic cylinder 8 to drive the support seat 71 to move, the position of the entire movable pressing assembly 7 can be adjusted, and the guide block slides smoothly along the inner wall of the guide groove 10. This guide structure can effectively limit the degree of freedom of the support seat 71 and prevent it from deviating from the predetermined path during movement, thereby ensuring the linearity and stability of the movement of the support seat 71 and avoiding unstable phenomena such as shaking and tilting caused by external interference or internal power fluctuations. This is not only conducive to the movable pressing assembly 7 to accurately reach the predetermined position, so as to achieve effective abutment against the object to be measured from four directions.

[0044] A multi-dimensional mechanical parameter synchronous measurement method is applicable to the multi-dimensional mechanical parameter synchronous measurement device mentioned above, comprising the following steps:

[0045] S1. Place the object to be measured on the bracket 6 so that the bottom end of the object to be measured presses against the pressure sensor 9;

[0046] S2, using the second hydraulic cylinder 8 to drive the support seat 71 to move, so as to use the fixed clamp block 72 to press the object to be measured from the side;

[0047] For an object to be measured with irregular sides, the motor 741 can be started, and the output end of the motor 741 can be used to drive the first connecting shaft 742 to rotate, so that the movable clamping block 73 on one side is deflected toward the direction of pressing the object to be measured. At the same time, the first gear 743, the second gear 745, the third gear 747 and the fourth gear 749 that are meshed in sequence rotate, which can drive the movable clamping block 73 on the other side to deflect toward the direction of pressing the object to be measured, so as to improve the stability of the side blocking;

[0048] S3, starting the first hydraulic cylinder 3 to drive the pressing member to move downward, and using the pressing member to squeeze the object to be measured;

[0049] S4. The sensor device monitors the mechanical parameters of each dimension in real time and transmits the monitoring data to the controller.
