Description

Technical Field

[0001] This utility model relates to the technical field of deformation testing platforms, specifically a double-headed hook spring deformation testing platform. Background Technology

[0002] Double-ended hook springs are key elastic components in machinery, automobiles, and other fields. Their deformation recovery performance directly determines the operational stability of end-use equipment. Reciprocating tensile deformation testing is a core step in assessing their service reliability, and related testing needs are becoming increasingly urgent as industrial manufacturing precision improves. Currently, mainstream testing in the industry mostly relies on general-purpose tensile testing machines. While these can meet basic tensile testing requirements, they lack dedicated positioning mechanisms for the special hook-shaped structure of double-ended hook springs. This can easily lead to loose clamping or force misalignment, resulting in inaccurate test data.

[0003] Existing testing equipment suffers from two major pain points: First, the transmission system mostly uses direct motor drive, lacking a stable speed reduction and torque amplification mechanism, resulting in large speed fluctuations during reciprocating tension, making it difficult to simulate the smooth force process under actual working conditions. Second, hook spring deformation monitoring largely relies on manual visual inspection or single-point displacement measurement, failing to achieve full-process visual recording and full-field deformation analysis, and manual operation is inefficient and difficult to adapt to batch testing needs. In addition, the clamping components of general-purpose equipment are not compatible with hook springs of different specifications, requiring frequent clamp changes, further reducing testing efficiency.

[0004] To address the issues of insufficient specialization and low testing accuracy and efficiency, the industry urgently needs to develop an integrated testing platform adapted to the structural characteristics of double-headed hook springs. Based on this, designing testing equipment that combines dedicated clamping and positioning, stable transmission, and real-time monitoring functions, specifically addressing the core requirements of double-headed fixing, reciprocating tension, and precise monitoring of hook springs, has become a key research and development direction for improving the quality inspection level of hook springs.

A worm gear is fixedly connected to the output end of the drive motor. The worm gear meshes with a transmission worm disc. A geared disc is coaxially fixedly connected to the worm disc and meshes with the transmission rack.

[0014] 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.

[0015] Example like Figure 1-5 As shown in the figure, an embodiment of the present invention proposes a double-headed hook spring deformation testing platform, including a platform plate 1. An industrial camera 2 is fixedly installed on the side of the platform plate 1. A front-end fixing component 3 is fixedly connected to the platform plate 1. The industrial camera 2 on the side of the platform plate 1 forms a monitoring linkage with the front-end fixing component 3 and the sliding fixing component 5. The industrial camera 2 can capture the deformation state of the hook spring between the front-end fixing component 3 and the sliding fixing component 5 in real time. Whether it is a single stretching or a reciprocating stretching process, the deformation of the hook spring can be completely recorded, providing clear and accurate image data for subsequent analysis of the hook spring deformation, and realizing the visualization monitoring and data retention of the testing process. Two guide rods 4 are fixedly installed in the middle of the front-end fixing component 3. A sliding fixing component 5 is slidably connected to the guide rod 4. The mounting base 51 of the sliding fixing component 5 is slidably connected to the guide rod 4. The guide rod 4 plays a precise guiding role in the sliding direction of the mounting base 51, ensuring that the sliding fixing component 5 always moves in a straight line during the movement, avoiding uneven force on the hook spring due to deviation, which would affect the accuracy of the test. The sliding fixed assembly 5 has a long rack 55 that passes through the transmission box 7. One end of the transmission box 7 is fixedly connected to a drive motor 8, and the output end of the drive motor 8 is fixedly connected to a worm 9. The worm 9 meshes with a transmission worm disk 10, and the worm disk 10 is coaxially 12 fixedly connected to a gear disk 11. The gear disk 11 meshes with the rack 55. The drive motor 8 serves as a power source, and its output end is fixedly connected to the worm 9, which can drive the worm 9 to rotate. The worm 9 meshes with the worm disk 10, which can transmit the motor power to the worm disk 10. At the same time, the structure of the worm 9 and worm disk 10 has a speed reduction and torque amplification function, ensuring stable transmission and that the output torque meets the tension requirements. The worm disk 10 is coaxially fixed with the gear disk 11 through the shaft 12, which can drive the gear disk 11 to rotate synchronously. The gear disk 11 meshes with the rack 55 of the sliding fixed assembly 5, which can convert the rotational motion into the linear motion of the rack 55, thereby driving the entire sliding fixed assembly 5 to move.

[0016] The working principle of this double-headed hook spring deformation testing platform for reciprocating tensile deformation testing is as follows: First, one end of the hook spring is fixed by the screw 34 of the front fixing component 3, and the other end of the hook spring is fixed by the screw 54 of the sliding fixing component 5. The parallel rod 53 assists in ensuring the stability of the hook spring installation. Then, the drive motor 8 is started, and its output end drives the worm gear 9 to rotate. The worm gear 9 meshes with the transmission worm disk 10, and the worm disk 10 drives the gear disk 11 to rotate through the coaxial 12. The gear disk 11 meshes with the rack 55 of the sliding fixing component 5, driving the mounting base 51 to slide away from the front fixing component 3 along the guide rod 4. The hook spring is stretched; when it slides to the maximum stroke or preset stretch amount limited by the limit block 6, the drive motor 8 is reversed, and the worm 9, worm disk 10, and gear disk 11 are driven in the opposite direction. The rack 55 drives the mounting seat 51 to slide along the guide rod 4 towards the front fixed component 3, so that the hook spring is reset. In this way, by the forward and reverse cycle of the drive motor 8, the mounting seat 51 slides back and forth along the guide rod 4, and the hook spring is stretched repeatedly. At the same time, the industrial camera 2 on the side of the platform plate 1 captures the deformation state of the hook spring in real time during each stretching process, and completes the deformation test of repeated stretching.

[0017] like Figure 3As shown, in some embodiments, the front-end fixing component 3 includes two L-shaped fixing blocks 31 that are fixed and symmetrical to the platform plate 1. One of the fixing blocks 31 has a mounting block 32 fixedly connected to its side wall. Two connecting posts 33 are fixedly connected between the mounting block 32 and the fixing block 31. A screw 34 is threaded onto the fixing block 31, located between the two connecting posts 33. A hook spring is used to fix it to the screw 34. The industrial camera 2 on the side of the platform plate 1 forms a monitoring linkage with the front-end fixing component 3 and the sliding fixing component 5. The industrial camera 2 can capture real-time data on the interaction between the front-end fixing component 3 and the sliding fixing component 5. The deformation state of the hook spring between the moving and fixed components 5 can be completely recorded, whether it is a single stretch or a reciprocating stretch process. This provides clear and accurate image data for subsequent analysis of the hook spring deformation, realizing the visualization monitoring and data retention of the test process. Fixed block 31: As the basic support of the component, it is L-shaped and symmetrically fixed with the platform plate 1. It not only ensures the stability of its connection with the platform plate 1, but also provides a stable mounting carrier for the mounting block 32, connecting column 33 and screw 34. The symmetrical design can balance the force and avoid the component tilting on one side from affecting the fixing accuracy of the hook spring.

[0018] like Figure 4 As shown, in some embodiments, the sliding fixing assembly 5 includes a mounting base 51 slidably connected to the guide rod 4. A connecting block 52 is fixedly connected to the upper side wall of the mounting base 51. Two parallel rods 53 are fixedly connected to the connecting block 52. A screw 54 is threadedly connected to the mounting base 51. A hook spring is used to fix it to the screw 54. A rack 55 is fixedly connected to one side of the mounting base 51. It has the functions of sliding guidance, hook spring fixing and power transmission. The components work together to ensure the stability and controllability of the test process.

[0019] like Figure 2 As shown, in some embodiments, the other end of the guide rod 4 is fixedly connected to the platform plate 1 via a limiting block 6, forming a rigid guide rail spanning the platform plate 1.

[0020] like Figure 5 As shown, in some embodiments, the worm 9, worm disk 10, shaft 12, and gear disk 11 are all rotatably mounted inside the transmission housing 7. On the one hand, the enclosed cavity structure provides protection for the internal transmission components, preventing external dust and impurities from interfering with the meshing of the components, and also preventing personnel from accidentally touching the rotating components during testing, thus improving operational safety. On the other hand, its fixed installation provides a precise assembly positioning reference for components such as the worm 9 and worm disk 10, ensuring the stability of the axial position of each transmission component, guaranteeing the accuracy of meshing transmission, and avoiding power transmission jamming or failure due to component misalignment.

[0021] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
