Description

Technical Field

[0001] This utility model relates to the field of material performance testing equipment, and in particular to a universal anti-lateral force device for a double-column testing machine. Background Technology

[0002] In the field of modern materials science and engineering, the double-column testing machine is a commonly used piece of equipment for performance testing. It uses a motor to drive a lead screw to rotate, causing the fixture to move along the axis of the lead screw, thereby applying tensile or compressive forces to the specimen. This allows for accurate evaluation of the mechanical properties of various materials. During the test, a force sensor measures the force applied to the specimen by the fixture in real time, and a displacement gauge measures the displacement of the fixture in real time. These data are transmitted to a computer through a measurement system. The computer calculates and displays the mechanical properties of the specimen, such as stress and strain, in real time based on preset test parameters and calculation formulas, providing a basis for material research and development, quality control, and engineering applications.

[0003] However, in practical applications, lateral forces are often generated due to factors such as the contact between the fixture and the specimen and the rigidity of the fixture itself. The impact of lateral force loading on test loading is multifaceted, including its effects on structural performance point displacement, plastic hinge distribution, seismic performance assessment, ultimate load, and material properties. These influencing factors need to be fully considered in structural design and evaluation.

[0004] To address the impact of lateral force loading, traditional methods often involve modifying the structure or focusing on improving the lateral force resistance of the hydraulic cylinder actuator. However, this increases the operating cost of the main unit. Since the standard testing machines commonly found on the market typically have a double-column structure, a structure is needed that can both eliminate the lateral force during testing and reduce the cost and increase the efficiency of the testing equipment. Therefore, a universal lateral force resistance device for double-column testing machines is proposed to solve the above problems. Utility Model Content

[0015] As a further description of the above technical solution:

[0016] The slide rail is located on the left inner wall of the positioning groove, and the right side of the column clamping block is set in a semi-open shape.

[0034] Reference Figure 1 , Figure 2 and Figure 3The top and bottom of the connecting plate 8 are provided with threaded flange interfaces 13. The upper end of the connecting plate 8 is connected to the clamp, and the lower end is connected to the actuator of the host. Multiple clamp interfaces can also be added to the upper end to realize the simultaneous loading and testing of multiple samples.

The front surface of the column clamping block 1 is provided with threaded holes for the installation of fixing screw 2 7. The column clamping block 1 is fixed to the column of the host by fixing screw 2 7. There are multiple sets of column clamping block 1, track guide plate 2, reinforcing rib plate 3, slide rail 10, slider 14, and horizontal plate 4. The multiple sets of column clamping block 1, track guide plate 2, reinforcing rib plate 3, slide rail 10, slider 14, and horizontal plate 4 are symmetrically arranged with the center line of the connecting plate 8 as the axis of symmetry. The top of another set of column clamping blocks 1 below the column clamping block 1 is provided with fixing screw 1 6. The bottom column clamping block 1 is fixed to the loading beam of the host by fixing screw 1 6.

[0035] Working principle: In use, the column clamping block 1, the track guide plate 2, and the reinforcing rib plate 3 are connected by welding.

By adjusting the screw depth of fixing screw 7, the column clamping block 1 can be fixed to the column of the main unit.

[0036] The adjusting shim 5 is made on-site according to the assembly situation. Due to the error in actual processing and assembly, the actual installation size of the adjusting shim 5 can be obtained by measuring tools according to the actual situation and modified to ensure the overall positioning of the device is accurate. The adjusting shim 5 is installed in the horizontal plate 4 and the slider 14, and the three are fixed together by fixing screws 39.

[0037] During the test, the connecting plate 8 is connected to the actuator of the main unit below, and the slider 14 is slidably connected to the left outer wall of the slide rail 10. When the lateral force generated during the test is transmitted to the slide rail 10, the slide rail 10 pulls the slider 14 and the horizontal plate 4, and at the same time pulls the connecting plate 8 and another set of anti-lateral components on the left side of the connecting plate 8. Thus, the two sets of anti-lateral components and the multiple sets of slide rails 10 work together to make the connecting plate 8 move only in a straight line, so that the actuator can only move in a straight line. Furthermore, the operation of the actuator is not affected by the lateral force, making the test more accurate.
