Description

Technical Field

[0001] This invention relates to the field of stress detection technology, specifically to a tension, compression, and torsion load measuring device and its operating method suitable for irregularly shaped components. Background Technology

[0002] In the fields of architecture, bridge construction, and mechanical engineering, irregularly shaped components are widely used in load-bearing structures and supporting members. These irregularly shaped components typically have complex geometries and structural forms, such as M-shaped, N-shaped, and X-shaped beams, columns, and joints. In practical applications, these irregularly shaped components are often subjected to a variety of complex mechanical forces, mainly including the combined action of tension, compression, and torsion, and often involve eccentric tension / compression and torsion combinations. To obtain accurate load-bearing capacity of irregularly shaped components, precise testing of their mechanical properties under different stress conditions is necessary.

[0003] Traditional testing loading devices typically use rectangular clamps to fix components, which are only suitable for regularly shaped components. However, when loading irregularly shaped components, the clamping ends are prone to localized failure before the main body of the component, making it difficult to meet the testing requirements of irregularly shaped components. Furthermore, existing loading devices are mostly single-type mechanical loading devices, capable only of pure compression or pure torsion, failing to meet the combined tensile, compressive, and torsional loading requirements of irregularly shaped components under actual working conditions. They also require the installation of additional torsion angle measuring instruments, and the torsion angle needs to be manually read or converted, introducing a certain degree of error. Therefore, this invention proposes a tensile, compressive, and torsional loading measurement device and operating method suitable for irregularly shaped components, to solve the problems of difficulty in testing combined loading of irregularly shaped components, cumbersome torsion angle testing process, and low accuracy in current technologies. Summary of the Invention

A magnetic chain is wrapped around the outside of an irregularly shaped component; the inner ring of the torsion toothed disc has a polygonal hole, and the torsion toothed disc is fitted around the magnetic chain outside the irregularly shaped component. Multiple electromagnetic blocks that repel the magnetic chain are arranged circumferentially on its inner ring, causing the magnetic chain to adhere to the surface of the irregularly shaped component under repulsive force and act as a clamp; the telescopic toothed plates of the two torsion components are respectively installed on the reaction component and the support; the two telescopic toothed plates of the same torsion component are located on both sides of the torsion toothed disc and are both engaged with the torsion toothed disc; the two telescopic toothed plates can extend and retract in opposite directions, driving the torsion toothed disc to rotate; the telescopic toothed plate installed on the support and the torsion toothed disc engaged with it can move synchronously along the extension direction of the irregularly shaped component.

[0007] Optionally, the telescopic toothed plate includes a kit, a limiting rack, and an electric telescopic rod; one torsion component kit is slidably mounted on the support along the extension direction of the irregular member, and the other torsion component kit is fixed to the reaction force component; the limiting rack is perpendicular to the extension direction of the irregular member and is slidably mounted on the kit along its own extension direction; there are two electric telescopic rods, located at both ends of the limiting rack, and both are mounted on the kit; the two electric telescopic rods alternately extend and retract, driving the limiting rack to move.

[0008] Optionally, the electric telescopic pole is equipped with an electronic measurement module for real-time detection of the telescopic amount and transmission to a computer for conversion to record the real-time torsion angle.

[0009] Optionally, the support includes a side plate, support slide rods, and support columns. There are two support columns, both vertically arranged with the side plate and located on the side of the side plate near the reaction force component. There are four support slide rods, all extending horizontally and arranged in a matrix. Each support slide rod connects to the support column and the side plate respectively. There are two kits for the same telescopic toothed plate, which are slidably installed on two support slide rods located on the same plane. Two support slide rods located on the same vertical plane are connected to the same support column, and the turntable is rotatably installed on the side plate.

[0010] Optionally, a circular groove is provided on the side plate, and the turntable is rotatably mounted in the circular groove.

[0011] Optionally, the jack is detachably equipped with a chuck at its top, which is used to connect with the irregularly shaped component and apply tension to the component; the jack directly abuts against the irregularly shaped component to apply pressure.

[0012] Optionally, the magnetic chain consists of multiple links, each of which is equipped with a permanent magnet. Adjacent links are hinged by pins and can be detached to adjust the length of the magnetic chain according to the outer contour length of the irregular component.

[0013] Optionally, one end of the magnetic chain is provided with a buckle for connecting and engaging with the other end of the magnetic chain after the magnetic chain is wrapped around the irregularly shaped component.

[0014] Optionally, the reaction component includes a rigid support and a reaction platform, the reaction platform being fixedly installed and its fixed position being adjustable, the rigid support being horizontally installed and fixed to the side of the reaction platform near the support, and another torsion component being fixed to the rigid support.

[0015] A method for measuring tension, compression, and torsion loads on irregularly shaped components, utilizing the aforementioned measuring device for such components, includes the following steps:

[0016] S10, Select the fixing position of the reaction force component according to the length of the irregular component;

[0017] S20, adjust the length of the magnetic chain according to the outer contour length of the irregular component cross section to achieve a better fit;

[0018] S30, the irregular component is placed in the hollow part of the torsion tooth disk of the two torsion components and magnetic chains are sleeved at the loading positions at both ends of the irregular component;

[0019] S40 is used to energize the electromagnet so that the magnetic chain adheres and locks the irregular component. By adjusting the magnitude of the electromagnet's magnetic force, the geometric center of the irregular component is aligned with the center of the torsion tooth disc.

[0020] S50, adjust the jack pressure position as needed to fix irregularly shaped components;

[0021] S60, depending on the actual stress condition of the test irregular component, select to apply equal and opposite torques to the torsion tooth discs of the two torsion components, or apply torque only to a single torsion tooth disc; or simultaneously activate the jack and the two telescopic tooth plates above and below the torsion tooth disc to make the torsion irregular component simultaneously subjected to tension and torsion or compression and torsion combined loading.

[0022] S70 calculates the torsion angle by the elongation of the telescopic toothed plate.

[0023] The beneficial effects of the present invention are: the tension, compression and torsion loading measuring device of the present invention for irregularly shaped components uses a magnetic chain to wrap around the loading positions at both ends of the irregularly shaped component, and uses an electromagnetic block to make the magnetic chain fit with the irregularly shaped component. This can effectively prevent the irregularly shaped component from being damaged at the loading position before the non-loading position during the loading process. Moreover, the length of the magnetic chain can be adjusted according to the cross-sectional outer contour length of different irregularly shaped components, making it highly adaptable.

[0024] Furthermore, this invention can not only perform tensile, compressive, torsional, and eccentric tensile, compressive, and torsional loading tests on irregularly shaped components, but also achieve free torsion and constrained torsional loading of irregularly shaped components through the coordinated use of two torsion toothed discs, making it widely applicable.

[0025] Furthermore, by extending and retracting the telescopic toothed plate to drive the rotation of the torsion toothed disc, the irregular component can be torsion. The elongation of the telescopic toothed plate can be used as the arc length corresponding to the torsion angle, and then the torsion angle of the irregular component can be calculated. This method is simple, quick, and highly accurate, and no additional torsion angle measuring instrument is required during the experiment. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] An embodiment of the present invention, applicable to tension, compression, and torsion loading measurement device for irregularly shaped components, is as follows: Figures 1 to 6 As shown, it includes a tension / compression eccentric load assembly, a torsion assembly, and a reaction force assembly.

[0036] The tension-compression eccentric loading assembly includes a support, a turntable 22, a sliding clamp 23, and a jack 24. The support is fixedly installed, the turntable 22 is mounted on the support and can rotate about a horizontal axis parallel to the extension direction of the irregular member 1. The sliding clamp 23 is slidably mounted on the turntable 22 along the radial direction of the turntable 22, and the jack 24 is mounted on the sliding clamp 23 for applying tension or compression to the irregular member 1 along the extension direction of the irregular member 1.

[0037] The reaction force assembly is used to install the other end of the irregular component 1, and its installation position is adjustable.

[0038] There are two torsion assemblies, located at both ends of the irregular component 1. Each torsion assembly includes a torsion toothed disc 32, a magnetic chain 33, and two telescopic toothed plates 31. The magnetic chain 33 is wrapped around the irregular component 1. The inner ring of the torsion toothed disc 32 has a polygonal hole. The torsion toothed disc 32 is fitted over the magnetic chain 33 on the irregular component 1, and its inner ring has multiple electromagnetic blocks 321 that repel the magnetic chain 33, causing the magnetic chain 33 to adhere to the surface of the irregular component 1 under repulsive force and to clamp it. The telescopic toothed plates 31 of the two torsion assemblies are respectively installed on the reaction force assembly and the support. The two telescopic toothed plates 31 of the same torsion assembly are located on both sides of the torsion toothed disc 32 and both mesh with the torsion toothed disc 32, making the torsion toothed disc 32 coaxial with the turntable 22. The two telescopic toothed plates 31 can extend and retract in opposite directions to drive the torsion toothed disc 32 to rotate. The telescopic toothed plates 31 installed on the support and the torsion toothed disc 32 meshing with them can move synchronously along the extension direction of the irregular component 1.

[0039] During measurement, both ends of the irregularly shaped component 1 pass through the torsion toothed discs 32 of two torsion assemblies, and are wound around the loading positions at both ends of the irregularly shaped component 1 by magnetic chains 33. Electromagnetic blocks 321 are used to ensure the magnetic chains 33 are in contact with the irregularly shaped component 1, effectively preventing the loaded position from breaking before the unloaded position during loading. Furthermore, the length of the magnetic chains 33 can be adjusted according to the cross-sectional outer contour length of different irregularly shaped components 1, providing strong adaptability. The two telescopic toothed plates 31 of the same torsion assembly extend and retract in opposite directions, driving the torsion toothed discs 32 to rotate, thereby causing the irregularly shaped component 1 to twist. The coordinated action of the telescopic toothed plates 31 of the two torsion assemblies allows the two ends of the irregularly shaped component 1 to twist in opposite directions, thus enabling a free torsion loading test on the irregularly shaped component 1. With one telescopic toothed plate 31 of the torsion assembly stationary and the two telescopic toothed plates 31 of the other torsion assembly extending and retracting in opposite directions, a constrained torsion loading test can be performed on the irregularly shaped component 1. In addition, the jack 24 can stretch the irregular component 1, and the jack 24 can move synchronously with the sliding clamp 23 to change its deflection position relative to the center of the turntable 22. Together with the torsion component, it can realize the tension, compression, torsion and eccentric tension, compression and torsion loading tests of the irregular component 1.

[0040] Furthermore, by extending and retracting the telescopic toothed plate 31, the torsion toothed plate 32 is rotated, thereby causing the irregular component 1 to twist. The elongation of the telescopic toothed plate 31 can be used as the arc length corresponding to the torsion angle, and then the torsion angle of the irregular component 1 can be calculated. This method is simple, quick, and highly accurate, and no additional torsion angle measuring instrument is required during the experiment.

[0041] In this embodiment, the telescopic toothed plate 31 includes a kit 311, a limiting rack 313, and an electric telescopic rod 312. One torsion assembly kit 311 is slidably mounted on the support along the extension direction of the irregular member 1, while the other torsion assembly kit 311 is fixed to the reaction force assembly. The limiting rack 313 is perpendicular to the extension direction of the irregular member 1 and is slidably mounted on the kit 311 along its own extension direction. The limiting rack 313 has a toothed groove, and the teeth on the torsion toothed disc 32 engage with the toothed groove on the limiting rack 313, allowing the torsion toothed disc 32 to slide synchronously with the limiting rack 313 along the extension direction of the irregular member 1 to accommodate the length change of the irregular member 1 caused by torsion. There are two electric telescopic rods 312, located at both ends of the limiting rack 313, and both are mounted on the kit 311. The two electric telescopic rods 312 alternately extend and retract, driving the limiting rack 313 to move.

[0042] In this embodiment, the electric telescopic pole 312 is equipped with an electronic measurement module for real-time detection of the telescopic amount and transmission to a computer for conversion and recording of the real-time torsion angle. In some other embodiments, an electric telescopic pole 312 capable of displaying the telescopic amount can also be selected. By recording the telescopic amount of each electric telescopic pole 312, the torsion angle can be calculated manually or by computer.

[0043] In this embodiment, the support includes a side plate 21, support slide rods 25, and support columns 26. There are two support columns 26, both vertically arranged with the side plate 21, and located on the side of the side plate 21 near the reaction force component. There are four support slide rods 25, all extending horizontally and arranged in a matrix. Each support slide rod 25 connects to the support column 26 and the side plate 21. There are two kits 311 of the same telescopic toothed plate 31, which are slidably installed on two support slide rods 25 located on the same plane. The two support slide rods 25 located on the same vertical plane are connected to the same support column 26. The turntable 22 is rotatably installed on the side plate 21. Specifically, a circular groove is provided on the side plate 21, and the turntable 22 is rotatably installed on the circular groove through a bearing or roller.

[0044] In this embodiment, a chuck 241 is detachably installed at the end of the jack 24. The chuck 241 is used to connect with the irregular component 1 and apply tension to the irregular component 1. The jack 24 directly abuts against the irregular component 1 and applies pressure to the irregular component 1.

[0045] In this embodiment, the magnetic chain 33 is composed of multiple links 333, each link 333 is equipped with a permanent magnet 334, and two adjacent links 333 are hinged by a pin 332. The two adjacent links 333 are detachable so as to adjust the length of the magnetic chain 33 according to the outer contour length of the irregular component 1.

[0046] In this embodiment, a buckle 331 is provided at one end of the magnetic chain 33, which is used to connect and fasten the magnetic chain 33 to the other end of the magnetic chain 33 after the magnetic chain 33 is wrapped around the irregular component 1.

[0047] In this embodiment, the reaction force assembly includes a rigid support 41 and a reaction force platform 42. The reaction force platform 42 is fixedly installed and its fixed position is adjustable. The rigid support 41 is horizontally installed and fixed to the side of the reaction force platform 42 near the support. Another torsion assembly component 311 is fixed to the rigid support 41. Specifically, there are four rigid supports 41 arranged in a matrix. There are two components 311 for the same telescopic toothed plate 31, which are fixedly installed on two rigid supports 41 located on the same plane.

[0048] The present invention provides a method for measuring tension, compression, and torsion loads on irregularly shaped components, utilizing the aforementioned measuring device for measuring tension, compression, and torsion loads on irregularly shaped components, comprising the following steps:

[0049] S10, Select the fixing position of the reaction force component according to the length of the irregular component 1;

[0050] S20, adjust the length of the magnetic chain 33 according to the outer contour length of the irregular component 1 to achieve a better fit;

[0051] S30, the irregular component 1 is placed in the hollow part of the torsion tooth disk 32 of the two torsion components and magnetic chains 33 are sleeved at the loading positions at both ends of the irregular component 1.

[0052] S40, the electromagnet is energized to make the magnetic chain 33 adhere and lock the irregular component 1, and the geometric center of the irregular component 1 is aligned with the center of the torsion tooth disk 32 by adjusting the magnitude of the electromagnet's magnetic force.

[0053] S50, adjust the pressure position of jack 24 as needed to fix the irregular component 1;

[0054] S60, depending on the actual stress condition of the test irregular component 1, select to apply equal and opposite torques to the torsion tooth disks 32 of the two torsion components, or apply torque only to the single torsion tooth disk 32; or simultaneously activate the jack 24 and the upper and lower telescopic tooth plates 31 of the torsion tooth disk 32 to make the torsion irregular component 1 simultaneously subjected to tension and torsion or compression and torsion combined loading.

[0055] S70, the torsion angle is calculated by the elongation of the telescopic toothed plate 31.

[0056] During the combined tension and torsion loading test, one end of the irregular component 1 is connected to the clamp 241 of the jack 24, and the other end needs to be fixed to the reaction platform 42 of the reaction component. During the eccentric tension, compression and torsion loading test, the position of the sliding clamp 23 on the turntable 22 needs to be adjusted, thereby changing the connection position between the jack 24 and the irregular component 1. After adjustment, the position of the sliding clamp 23 on the turntable 22 needs to be fixed to prevent slippage during torsion.
