Description

Technical Field

[0001] This utility model relates to the field of bicycle frame testing technology, specifically a carbon fiber bicycle frame compression testing platform. Background Technology

[0002] Carbon fiber bicycles are high-performance bicycles manufactured using carbon fiber composite materials as their core. Key components such as the frame, fork, and wheelset are largely made of carbon fiber. Carbon fiber is a special fiber composed of carbon elements, possessing properties such as lightweight, high strength, corrosion resistance, and high-temperature resistance. Its density is only 1 / 4 that of steel, but its strength can be more than 5 times that of steel. This material characteristic allows carbon fiber bicycles to significantly reduce weight while maintaining structural strength, making them the preferred choice for high-end racing, fitness cycling, and sports equipment. During the production of carbon fiber bicycles, a compression testing bench is typically used to evaluate the structural strength and test the resistance to deformation. A compression testing bench is a mechanical device used to test the performance of materials or structures under pressure. It simulates the pressure environment that a product might encounter in actual use by applying controlled compressive force, thereby evaluating its compressive strength, rigidity, deformation, or failure limit. By testing whether the strength of the carbon fiber frame under pressure meets design requirements and industry standards, it can be confirmed whether the frame can safely bear the rider's weight and the impact force generated during riding. At the same time, analyzing the deformation of the frame under pressure can determine whether its rigidity and elasticity are reasonable, which can effectively prevent safety accidents caused by structural failure.

[0003] In the prior art, when performing compression testing on a bicycle frame using a compression testing bench, the frame's geometry cannot be well fixed, making it prone to displacement under pressure. This compromises the frame's stability and the consistency of testing conditions, leading to data deviations due to displacement. Consequently, it is detrimental to improving the accuracy and reliability of the test. Therefore, to address these issues, a carbon fiber bicycle frame compression testing bench is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a carbon fiber bicycle frame compression testing platform to solve the problem mentioned in the background art, which is that the frame is prone to displacement under pressure due to the inability to fix the geometric shape of the frame well, thus failing to ensure the stability of the frame and the consistency of the test conditions, resulting in data deviation due to displacement, which is not conducive to improving the accuracy and reliability of the test.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a carbon fiber bicycle frame compression testing platform, comprising a platform body, a placement plate disposed on the surface of the platform body, a support frame fixedly connected to the upper surface of the platform body, a telescopic cylinder fixedly installed on the lower surface of the support frame, a force sensor fixedly connected to the output end of the telescopic cylinder, a pressure head fixedly connected to the bottom end of the force sensor, a displacement sensor fixedly installed on the surface of the support frame, a limiting mechanism disposed on the surface of the placement plate, a feeding mechanism disposed on the inner side of the platform body, the limiting mechanism comprising a first limiting plate disposed at the top of the placement plate, a second limiting plate disposed on the surface of the first limiting plate, the feeding mechanism comprising a second screw movably connected to the inner side of the platform body, a third moving block threadedly connected to the surface of the second screw, the third moving block being fixedly connected to the bottom end of the placement plate.

[0006] Preferably, the limiting mechanism further includes a first movable groove, which is formed on the inner side of the placement plate, and a positive and negative screw is movably connected to the inner side of the first movable groove. The positive and negative screw is movably connected to the placement plate, and a first motor is fixedly installed on the surface of the placement plate.

The first limiting plate is fixedly connected to the top of the connecting block. A limiting groove is opened on the inner side of the placement plate, and the connecting block is movable inside the limiting groove.

[0008] Preferably, a second movable groove is provided on the inner side of the first limiting plate, a first threaded rod is movably connected to the inner side of the second movable groove, and the first threaded rod is movably connected to the first limiting plate. A second motor is fixedly installed on the surface of the first limiting plate, and the first threaded rod and the output end of the second motor are fixedly connected.

[0009] Preferably, the surface of the first threaded rod is threadedly connected to a second movable block, and the second limiting plate and the second movable block are fixedly connected, with the second movable block moving inside the second movable groove.

[0010] Preferably, the feeding mechanism further includes a third movable groove, which is opened on the inner side of the platform, and the second screw moves on the inner side of the third movable groove.

[0011] Preferably, a slider is fixedly connected to the lower surface of the placement plate, a groove is provided on the inner side of the platform, and the end of the slider away from the placement plate moves within the groove, while the third moving block moves within the third movable groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The rotation of the positive and negative screws enables the first moving block to move the connecting block and the first limiting plate, thereby facilitating the limiting of the left and right sides of the frame through the first limiting plate. The rotation of the first threaded rod enables the second moving block to move the second limiting plate, thereby facilitating the limiting of the front and rear of the frame through the second limiting plate. The cooperation of the first and second limiting plates ensures the stability of the frame and constrains the frame, thus preventing the frame from shifting due to pressure. This helps to ensure the quality and accuracy of frame inspection.

[0014] 2. The third motor drives the second screw to rotate, which in turn moves the third moving block to move the placement plate. This facilitates the movement of the frame to or from under the pressure head, making it easier to load and unload the frame. This also prevents accidental injury to workers due to misoperation by moving the frame away from the pressure head, thus improving the safety of the inspection. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] The telescopic cylinder 13, force sensor 14, displacement sensor 16, first motor 22, second motor 29 and third motor 32 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0024] A carbon fiber bicycle frame compression resistance testing platform includes a platform body 1. A placement plate 11 is provided on the surface of the platform body 1. A support frame 12 is fixedly connected to the upper surface of the platform body 1. A telescopic cylinder 13 is fixedly installed on the lower surface of the support frame 12. A force sensor 14 is fixedly connected to the output end of the telescopic cylinder 13. A pressure head 15 is fixedly connected to the bottom end of the force sensor 14. A displacement sensor 16 is fixedly installed on the surface of the support frame 12. A limit mechanism is provided on the surface of the placement plate 11. A feeding mechanism is provided inside the platform body 1. The limit mechanism includes a first limit plate 25, which is disposed on the placement plate 11. The top of the first limiting plate 25 is provided with a second limiting plate 211. The feeding mechanism includes a second screw 31, which is movably connected to the inner side of the platform 1. A third moving block 33 is threadedly connected to the surface of the second screw 31. The third moving block 33 is fixedly connected to the bottom end of the placement plate 11. The frame can be placed by the placement plate 11. The pressure head 15 is driven to move vertically by the telescopic cylinder 13, so that the pressure head 15 applies pressure to the frame. The pressure value and deformation data are collected by the force sensor 14 and the displacement sensor 16, so that the compressive strength of the frame can be analyzed.

[0025] Furthermore, the limiting mechanism also includes a first movable groove 2, which is opened on the inner side of the placement plate 11. A positive and negative screw 21 is movably connected to the inner side of the first movable groove 2. The positive and negative screw 21 is movably connected to the placement plate 11. A first motor 22 is fixedly installed on the surface of the placement plate 11. The positive and negative screw 21 is fixedly connected to the output end of the first motor 22. By rotating the positive and negative screw 21, the first moving block 23 can drive the connecting block 24 and the first limiting plate 25 to move, thereby enabling the first limiting plate 25 to limit the two sides of the frame, ensuring the stability of the frame position on the placement plate 11, thus facilitating better testing.

[0026] Furthermore, the surface of the positive and negative screws 21 is threaded with a first moving block 23. The first moving block 23 moves inside the first moving groove 2, and a connecting block 24 is fixedly connected to the top of the first moving block 23. The first limiting plate 25 is fixedly connected to the top of the connecting block 24. A limiting groove 26 is opened on the inner side of the placement plate 11, and the connecting block 24 moves inside the limiting groove 26. By setting the limiting groove 26, the connecting block 24 can be limited, thereby preventing the first moving block 23 from shifting under the action of the positive and negative screws 21. This ensures that the connecting block 24 drives the first limiting plate 25 to move, so that the first limiting plate 25 can limit the two ends of the frame.

[0027] Furthermore, a second movable groove 27 is provided on the inner side of the first limiting plate 25. A first threaded rod 28 is movably connected to the inner side of the second movable groove 27, and the first threaded rod 28 is movably connected to the first limiting plate 25. A second motor 29 is fixedly installed on the surface of the first limiting plate 25, and the output ends of the first threaded rod 28 and the second motor 29 are fixedly connected. By opening the second movable groove 27, the second moving block 210 can be limited, which can prevent the second moving block 210 from deviating under the action of the first threaded rod 28, thereby ensuring the stable movement of the second moving block 210.

[0028] Furthermore, the surface of the first threaded rod 28 is threadedly connected to the second moving block 210, and the second limiting plate 211 and the second moving block 210 are fixedly connected. The second moving block 210 moves inside the second moving groove 27. Through the setting of the second moving block 210 and the second limiting plate 211, the second moving block 210 can drive the second limiting plate 211 to move under the action of the first threaded rod 28. In this way, the position of the second limiting plate 211 can be adjusted according to the size of the frame, so that the second limiting plate 211 can limit the front and rear ends of the frame, making the frame more stable and better ensuring the quality of testing.

[0029] Furthermore, the loading mechanism also includes a third movable groove 3, which is located inside the platform 1. The second screw 31 moves within the third movable groove 3. A third motor 32 is fixedly installed on the surface of the platform 1, and the output ends of the second screw 31 and the third motor 32 are fixedly connected. By rotating the second screw 31, the third moving block 33 can drive the placement plate 11 to move, so that the placement plate 11 can be located below or away from the pressure head 15, which facilitates loading and unloading of the frame and avoids accidental damage from the pressure head 15 during the loading and unloading process.

[0030] Furthermore, a slider 34 is fixedly connected to the lower surface of the placement plate 11, and a groove 35 is provided on the inner side of the platform 1. The end of the slider 34 away from the placement plate 11 moves within the groove 35, and the third moving block 33 moves within the third moving groove 3. By setting the slider 34 and opening the groove 35, the placement plate 11 can be limited, and the placement plate 11 can be prevented from shifting under the action of the second screw 31 and the third moving block 33.

[0031] Working principle: In use, the first motor 22 is electrically connected to an external power source. The operator starts the first motor 22 by pressing the switch. The first motor 22 drives the positive and negative screws 21 to rotate. The connecting block 24 is limited by the limiting groove 26, which causes the first moving block 23 to move inside the platform 1 under the action of the positive and negative screws 21. Then, the connecting block 24 moves inside the limiting groove 26 and drives the first limiting plate 25 to move, so that the first limiting plate 25 can limit the left and right sides of the frame. The second motor 29 is electrically connected to an external power source. The operator starts the second motor 29 by pressing the switch. The second motor 29 drives the first threaded rod 28 to rotate. The second moving block 210 is limited by the second moving groove 27. It moves under the action of the first threaded rod 28 and drives the second limiting plate 211 to move accordingly, so that the second limiting plate 211 limits the front and rear of the frame.

[0032] The third motor 32 is electrically connected to an external power source. The operator starts the third motor 32 by pressing a switch. The operation of the third motor 32 drives the second screw 31 to rotate. The placement plate 11 is limited by the slider 34 and the slide groove 35, which causes the third moving block 33 to move inside the third movable groove 3 under the action of the second screw 31. As a result, the placement plate 11 moves and the slider 34 moves inside the slide groove 35, thereby enabling the frame to be moved below the pressure head 15 or removed from below the pressure head 15.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
