Description

Technical Field

[0001] This utility model relates to the field of tensile testing technology, and in particular to a multi-angle gantry tensile testing table. Background Technology

[0002] Tensile testing is an important experimental method for determining the mechanical properties of materials under stress. Through tensile testing, key parameters such as stress-strain curves, elastic modulus, yield strength, and fracture strength can be obtained, thereby evaluating the mechanical properties of the material.

[0003] Currently, the angles of the upper and lower clamps in tensile testing devices on the market are not adjustable and are all fixed, which can only perform axial tension on the workpiece. However, in actual operation, some rods have a certain angle between the upper and lower parts (such as the guide rod of the rear suspension of automobiles, tie rod, etc.). It is difficult to obtain test data under different angle tension conditions by using only axial tension. Therefore, the existing tensile testing devices cannot meet the test requirements of rods with a certain angle between the upper and lower parts, resulting in insufficient test data to support deformation analysis. To address this, a multi-angle gantry tensile testing table is proposed. Utility Model Content

The second screws 13 are rotatably connected to the fixed frames 4 through bearings. The inner ring of the bearing is fixedly connected to the second screws 13, and the outer ring of the bearing is fixedly connected to the fixed frames 4.

[0026] Two mounting shafts 21 are rotatably fitted onto adjacent sides of the outer surfaces of the two slides 10. Each mounting shaft 21 and the adjacent slide 10 are connected to an electric rotating component. The electric rotating component includes a third motor 20, which is fixedly installed inside the adjacent slide 10. The drive end of the third motor 20 is fixedly connected to a drive gear 22.

[0030] Working principle: The upper workpiece clamp 12 and lower workpiece clamp 8 are adjusted according to the workpiece specifications and the required stretching angle. The first motor 6 operates, driving the first screw 9 to rotate. The first screw 9 moves the slider 17, which in turn moves the lower workpiece clamp 8 until the desired position is reached. The second motor 15 operates, driving the connected synchronous pulley 18 to rotate. The rotating synchronous pulley 18 drives another synchronous pulley 18 to rotate via the synchronous belt 14, thus synchronously driving the two second screws 13 to rotate. The second screws 13 drive the slide 10 to rise. The slide 10, through the mounting shaft 21 and mounting base 7, drives the hydraulic cylinder 5 to rise, and then... Force sensor 16 drives the upper workpiece clamp 12 to rise to the set height. Then, the third motor 20 runs, driving the connected drive gear 22 to rotate. The drive gear 22 drives the mounting shaft 21 to rotate through the gear ring 19, thereby driving the mounting base 7 to rotate. The mounting base 7 drives the hydraulic cylinder 5 and the tension sensor 16 to rotate, changing the angle of the upper workpiece clamp 12 until the desired angle is reached. Then, the bottom end of the workpiece is clamped and fixed perpendicularly to the lower workpiece clamp 8. Then, the upper end of the workpiece is clamped and fixed through the upper workpiece clamp 12 at the desired angle. Then, the hydraulic cylinder 5 runs, driving the upper workpiece clamp 12 to move in the set direction through the tension sensor 16, stretching the workpiece.
