Description

Technical Field

[0001] This utility model relates to the field of torsional deformation testing technology, specifically to a torsional deformation testing device. Background Technology

[0002] During the production of metal parts, torsional deformation tests are typically performed. These tests primarily verify the metal parts' ability to resist deformation under external forces, a crucial performance indicator. For example, in patent CN216646068U, titled "An Underwater Buoyancy Cable Torsional Resistance Testing Device," a first motor controls the rotation of a first drive wheel. This drive wheel meshes with a rack, causing the connecting tube to rotate, thus enabling the torsional resistance test of the buoyancy cable. After adjusting the clamping mechanism to control the torsion of the buoyancy cable, when the connecting tube returns to its original position, the first drive wheel... Two motors control the rotation of the second drive wheel, which meshes with the gear disc. The second drive wheel drives the gear disc to rotate, allowing the infrared laser rangefinder to scan and detect the portion of the buoyancy cable near the torsion point. If the infrared ranging signal shows a slight bend, it indicates damage to the buoyancy cable. Detection is performed when the connecting pipe is reset, making it easier to check for damage compared to when the buoyancy cable is stationary. Support columns maintain the stability of the arc-shaped sliding bracket. However, the above structure still has the following problems in actual use:

[0003] During use, the above structure rotates the connecting pipe by meshing with the rack and pinion, thereby achieving torsion resistance testing. Due to the obstruction of the threaded rod, the angle of torsion is limited. Insufficient torsion angle can easily lead to inaccurate test results, thus failing to effectively test the torsion deformation resistance of metal parts.

[0004] Therefore, we proposed a torsional deformation testing device that can effectively solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a torsional deformation testing device to solve the problem mentioned in the background art that the insufficient torsion angle in the current market easily leads to inaccurate test results, thus making it impossible to effectively test the torsional deformation resistance of metal parts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a torsional deformation testing device, including a test platform and a servo motor bolted to the left side of the test platform for providing power;

[0007] It also includes: the output end of the servo motor is fixed to one end of the threaded rod, and the other end of the threaded rod extends into the interior of the test bench to form a rotating connection structure with the test bench, and a gear is also fixed to the outside of the threaded rod;

[0008] The upper end of the gear is provided with a torsion mechanism, which drives the clamped metal parts to twist through the rotation of the connecting ring.

[0009] Preferably, the torsion mechanism includes a gear ring and a connecting ring, wherein the gear ring is fixed to the left side of the connecting ring, and the lower end of the gear ring meshes with a gear.

[0010] Preferably, the connecting ring is fixed to the upper surface of the test bench by a limiting ring, and the connecting ring and the limiting ring form a rotating connection structure.

[0011] Preferably, a worm is provided on the right side of the connecting ring, and the left end of the worm extends into the interior of the connecting ring and is connected to the bearing of the connecting ring. Furthermore, a worm wheel meshes with the outer side of the worm, and the inner side of the worm wheel is fixed to the threaded sleeve.

[0012] Preferably, the internal thread of the threaded sleeve is connected to a limiting screw, and the limiting screw and the connecting ring are in a sliding connection structure. Furthermore, the inner end of the limiting screw extends out to the connecting ring and is fixed to the clamping plate.

[0013] Preferably, the clamping plates are provided in two sets, and the clamping plates are arranged in an up-down direction, and the lower end of the lower clamping plate is fixed to the inner side of the connecting ring.

[0014] Preferably, the outer side of the threaded rod is threadedly connected to a mounting plate, and the upper end of the mounting plate extends out of the upper end face of the test platform. An adjusting screw is provided on the upper end face of the mounting plate, and the lower end of the adjusting screw extends to the inner side of the mounting plate and forms a bearing connection structure with the mounting plate. Furthermore, a clamping block is threadedly connected to the outer side of the adjusting screw, and two sets of clamping blocks are provided. The lower clamping block is fixedly connected to the mounting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: this torsional deformation testing equipment not only greatly improves the torsion angle, thereby improving the testing effect and making the test results more accurate, but also facilitates the clamping of metal parts and can perform tensile tests on metal parts, thus increasing functionality while eliminating the need for other testing equipment, saving costs. The specific details are as follows:

[0016] (1) The connecting ring is fixed on the test bench by the limiting ring. At the same time, the connecting ring and the limiting ring are in a rotating connection structure, which allows the connecting ring to rotate 360 ​​degrees, thereby greatly increasing the angle of torsion, thus improving the test effect and making the test results more accurate.

[0017] Furthermore, by rotating the threaded rod, the threaded rod drives the gear to rotate together, which in turn drives the meshing gear ring to rotate synchronously. The rotation of the gear ring drives the connecting ring to rotate together, which in turn drives the metal parts fixed inside to twist, thereby achieving the effect of torsion testing.

[0018] (2) The worm rotates while driving the meshing worm wheel to rotate together, which in turn drives the inner threaded sleeve to rotate together, which in turn drives the limit screw downward while the threaded sleeve rotates, so that the limit screw can drive the clamping plate fixed at its inner end to move closer to and further away from another set of clamping plates, thus facilitating the clamping of metal parts.

[0019] Because of the sliding connection structure between the limiting screw and the connecting ring, the limiting screw will not rotate with the threaded sleeve. Therefore, the limiting screw can move up and down while the threaded sleeve rotates.

[0020] As the threaded rod rotates, it also moves the mounting plate connected to it to the right, which in turn moves the clamped metal parts to the right, allowing for tensile testing of the metal parts. This increases functionality and eliminates the need for separate testing equipment, saving costs. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 The present invention provides the following technical solution:

[0030] Example 1: To address the problem in the prior art where insufficient torsion angle easily leads to inaccurate test results, thus hindering the effective testing of the torsional deformation resistance of metal parts, the following solution is disclosed: A test bench 1 and a servo motor 2 bolted to the left side of the test bench 1 for providing power; The solution also includes: the output end of the servo motor 2 is fixed to one end of a threaded rod 3, and the other end of the threaded rod 3 extends into the interior of the test bench 1, forming a rotatable connection structure with the test bench 1; a gear 4 is fixed to the outside of the threaded rod 3; a torsion mechanism is provided at the upper end of the gear 4, which drives the clamped metal parts to torsion through the rotation of a connecting ring 6. The torsion mechanism includes a gear ring 5 and a connecting ring 6, wherein the gear ring 5 is fixed to the left side of the connecting ring 6, and the lower end of the gear ring 5 meshes with the gear 4; the connecting ring 6 is fixed to the upper surface of the test bench 1 through a limiting ring 7, and the connecting ring 6 and the limiting ring 7 form a rotatable connection structure.

[0031] First, by starting the servo motor 2, the servo motor 2 drives the threaded rod 3 to rotate. The rotation of the threaded rod 3 drives the gear 4 to rotate, which in turn drives the meshing gear ring 5 to rotate synchronously. The rotation of the gear ring 5 then drives the connecting ring 6 to rotate, which in turn causes the metal parts fixed inside the connecting ring 6 to twist, thus achieving the effect of torsion testing. The connecting ring 6 is fixed to the test table 1 by the limiting ring 7, and the connecting ring 6 and the limiting ring 7 have a rotating connection structure, which allows the connecting ring 6 to rotate 360 ​​degrees, thus greatly increasing the torsion angle and improving the test effect, making the test results more accurate.

[0032] Example 2: Based on Example 1, a new technical solution is added to facilitate the clamping of metal parts. See details below. Figures 5-6A worm 8 is provided on the right side of the connecting ring 6, and the left end of the worm 8 extends into the interior of the connecting ring 6 and is connected to the bearing of the connecting ring 6. A worm wheel 9 is engaged on the outer side of the worm 8, and the inner side of the worm wheel 9 is fixed to the threaded sleeve 10. The threaded sleeve 10 is connected to a limiting screw 11 by a thread, and the limiting screw 11 and the connecting ring 6 have a sliding connection structure. The inner end of the limiting screw 11 extends out of the connecting ring 6 and is fixed to the clamping plate 12. Two sets of clamping plates 12 are provided, and the clamping plates 12 are arranged in the vertical direction. The lower end of the lower clamping plate 12 is fixed to the inner side of the connecting ring 6.

[0033] Moreover, during testing, simply pass one end of the metal component through the connecting ring 6 and place it between the clamping plates 12. Then, rotate the worm gear 8. The rotation of the worm gear 8 causes the meshing worm wheel 9 to rotate as well. The rotation of the worm wheel 9 causes the threaded sleeve 10 on its inner side to rotate as well. As the threaded sleeve 10 rotates, it causes the limiting screw 11 to move downward. Because of the sliding connection structure between the limiting screw 11 and the connecting ring 6, the limiting screw 11 will not rotate with the threaded sleeve 10. Therefore, while the threaded sleeve 10 rotates, the limiting screw 11 can move up and down. This allows the limiting screw 11 to move the clamping plate 12 fixed at its inner end closer to or further away from another set of clamping plates 12, thus facilitating the clamping of the metal component.

[0034] Example 3: Based on Example 1, a new technical solution is added to perform tensile testing on metal parts. This increases functionality and eliminates the need for separate testing equipment, saving costs. See details for further information. Figures 1-2 The outer side of the threaded rod 3 is threadedly connected to the mounting plate 13. The upper end of the mounting plate 13 extends out of the upper end face of the test bench 1. An adjusting screw 14 is provided on the upper end face of the mounting plate 13. The lower end of the adjusting screw 14 extends to the inner side of the mounting plate 13 and forms a bearing connection structure with the mounting plate 13. A clamping block 15 is also threadedly connected to the outer side of the adjusting screw 14. Two sets of clamping blocks 15 are provided, and the lower clamping block 15 is fixedly connected to the mounting plate 13.

[0035] Meanwhile, the other end of the metal component extends between the clamping blocks 15. At this time, by rotating the adjusting screw 14, the clamping blocks 15 connected to its outer thread can be moved, so that the upper clamping block 15 moves closer to the lower clamping block 15. The two sets of clamping blocks 15 limit the metal component, which facilitates torsion testing and fixation of the metal component. Moreover, when the threaded rod 3 rotates, it will also drive the mounting plate 13 connected to it to move to the right, so that the mounting plate 13 drives the clamped metal component to the right, and then the metal component can be subjected to tensile testing. This increases functionality and eliminates the need for other testing equipment, saving costs.

[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
