Technical Field

[0001] This utility model relates to the technical field of strength testing devices, specifically a positioning device for testing the strength of carbon fiber bicycle frames. Background Technology

[0002] The bicycle frame, as the skeleton of the entire bicycle, largely determines and influences the correctness and comfort of riding posture. It is the basic structural component of the bicycle, its skeleton and main body; other parts are directly or indirectly mounted on the frame. Many materials are used to manufacture bicycle frames, and carbon fiber bicycle frames, as a superior option, possess advantages over traditional frames, including lightness, high rigidity, and excellent shock absorption. They are widely used in various racing bicycles. After manufacturing, carbon fiber bicycle frames require rigorous strength testing. To ensure that the quality of the bicycle meets standards during subsequent assembly, existing technologies for strength testing of the bicycle frame include devices with a front-end fixed connection and a rear-end fixed frame. The front-end fixed frame is generally sliding, allowing for the placement of frames of different sizes. It also has limit components to limit the movement of the slider. The rear-end fixed frame can test the entire frame. However, some devices do not have a limit and fixation treatment for the middle position of the frame, which may lead to instability during the frame testing process.

[0003] A positioning device for testing the strength of carbon fiber bicycle frames is proposed to address the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a positioning device for testing the strength of carbon fiber bicycle frames, in order to solve the problem mentioned in the background art. In the existing technology, when testing the overall strength of a bicycle frame, some devices are divided into a front fixed connection and a rear fixed frame. The front fixed frame is generally sliding, which allows for the placement of frames of different sizes. At the same time, the front fixed frame is equipped with a limiting component to limit the movement of the slider. The rear fixed frame can test the entire frame. However, some devices do not have a limiting and fixing treatment for the middle position of the frame, which may lead to instability during the frame testing process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for testing the strength of a carbon fiber bicycle frame, comprising a base, wherein a front-end fixing bracket is fixedly installed on one side of the top surface of the base; A rear end bracket is fixedly installed on the other side of the top surface of the base. T-shaped grooves are symmetrically opened on the top surface of the front end fixed connection. A T-shaped block is slidably connected inside the T-shaped groove. A connecting block is fixedly connected to the top surface of the T-block. A stabilizing block is fixedly connected to the middle of the top surface of the connecting block. A fixing element is provided in the middle of the surface of the stabilizing block. Also includes: A mid-end limiting component is provided in the middle of the top surface of the base; The mid-end limiting component includes a connecting box that is fixedly connected to the base; The connecting box has a sliding support block inside.

[0006] Preferably, the connecting box has symmetrically formed grooves inside, and a slider is slidably connected inside the groove. The side surface of the slider away from the groove is fixedly connected to the bearing block.

[0007] Preferably, an electric push rod is fixedly installed inside the connecting box, and an elastic rubber pad is fixedly connected to the top surface of the electric push rod. The top surface of the elastic rubber pad is fixedly connected to the bearing block.

[0008] Preferably, a stabilizing frame is connected through the surface of the electric push rod, the bottom surface of the stabilizing frame is fixedly connected to the connecting box, and a rubber gasket is fixedly installed inside the stabilizing frame, the rubber gasket being in close contact with the electric push rod.

[0009] Preferably, the stabilizing frame is made of stainless steel.

[0010] Preferably, the top surface of the support block is fixedly connected to the stabilizing block.

[0011] Preferably, a detection device is provided on one side surface of the rear end fixing frame, and the top surface of the rear end fixing frame is fixedly connected to the stabilizing block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This positioning device for testing the strength of carbon fiber bicycle frames, by setting a mid-end limiting component, can provide a more precise limiting and fixing of the entire frame, improving the accuracy and stability of the frame position during testing, and ensuring the reliability of the test results. Meanwhile, the front and rear fixing brackets can be adjusted according to different frame sizes and used for testing the frame. The specific details are as follows: 1. By setting a mid-range limiting component, during the overall frame testing, after the front and rear fixing brackets secure the frame, the electric push rod is activated via the control terminal. This allows the output of the electric push rod to lift the elastic rubber pad, load-bearing block, and stabilizing block. Once the holes on the stabilizing block align with the holes on the frame, the fixing component passes through these holes, thus limiting and fixing the mid-range of the frame. This allows for more precise limiting and fixing, improving the accuracy and stability of the frame position during testing, and ensuring the quality of the test. The reliability of the results is ensured by the elastic rubber pads, which can buffer the vibration force generated during the frame test and reduce the transmission of vibration force to the electric push rod. At the same time, the electric push rod housing is also equipped with a stabilizing bracket and rubber gaskets to prevent the electric push rod housing from twisting or deforming due to vibration, thereby protecting the normal operation of internal components such as motors and transmission mechanisms. Meanwhile, the rubber gaskets can buffer the vibration force transmitted from the electric push rod, thereby avoiding contact between the electric push rod housing and the stabilizing bracket, which could lead to damage to the electric push rod housing or the stabilizing bracket. 2. By setting up a front-end fixing bracket and a rear-end fixing bracket, during the frame testing, after measuring the size of the frame, the rear end of the frame is connected and fixed to the rear-end fixing bracket. The front end of the frame is placed on the front-end fixing bracket, and the limiting device on the T-block is removed, allowing the connecting block, stabilizing block, and fixing component to move. After the connecting block, stabilizing block, and fixing component move to the appropriate position, the limiting device limits the T-block, thereby stabilizing the connecting block, stabilizing block, and fixing component, allowing the front end of the frame to be connected to the front-end fixing bracket. Then, the middle limiting component limits and fixes the middle of the frame. Finally, the entire frame is tested using a testing device. Attached Figure Description

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-6 This utility model provides a technical solution: a positioning device for testing the strength of a carbon fiber bicycle frame, including a base 1, a front-end fixing bracket 2 fixedly installed on one side of the top surface of the base 1; a rear-end fixing bracket 3 fixedly installed on the other side of the top surface of the base 1, T-shaped grooves 5 symmetrically opened on the top surface of the front-end fixing bracket, a T-shaped block 6 slidably connected inside the T-shaped groove 5, a connecting block 7 fixedly connected to the top surface of the T-shaped block 6, a stabilizing block 8 fixedly connected to the middle of the top surface of the connecting block 7, and a fixing member 9 provided in the middle of the surface of the stabilizing block 8; it also includes: a middle-end limiting component 4 provided in the middle of the top surface of the base 1; wherein, the middle-end limiting component 4 includes a connecting box 401 fixedly connected to the base 1; wherein, a bearing block 402 is slidably connected inside the connecting box 401, such as Figure 1-6 As shown, by setting the middle limiting component 4, the frame can be more accurately limited and fixed, improving the accuracy and stability of the frame position during testing and ensuring the reliability of the test results. Meanwhile, the front fixing bracket 2 and the rear fixing bracket can be adjusted according to different frame sizes and used for testing the frame.

[0017] The connecting box 401 has symmetrically arranged sliding grooves 403 inside. A slider 404 is slidably connected inside the sliding grooves 403. The surface of the slider 404 away from the sliding grooves 403 is fixedly connected to the bearing block 402. An electric push rod 405 is fixedly installed inside the connecting box 401. An elastic rubber pad 406 is fixedly connected to the top surface of the electric push rod 405. The top surface of the elastic rubber pad 406 is fixedly connected to the bearing block 402. A stabilizing frame 407 is connected through the surface of the electric push rod 405. The bottom surface of the stabilizing frame 407 is fixedly connected to the connecting box 401. A rubber washer 408 is fixedly installed inside the stabilizing frame 407. The rubber washer 408 is in close contact with the electric push rod 405. The stabilizing frame 407 is made of stainless steel. The top surface of the bearing block 402 is fixedly connected to the stabilizing block 402. Figure 4-6 As shown, the electric push rod 405 is activated via the control terminal, causing its output end to lift the elastic rubber pad 406, the bearing block 402, and the stabilizing block 8. This aligns the holes in the stabilizing block 8 with the holes in the frame. By passing the fixing piece 9 through the holes in both the stabilizing block 8 and the frame, the middle section of the frame can be fixed in a more precise manner. This improves the accuracy and stability of the frame position during testing, ensuring the reliability of the test results. Simultaneously, the elastic rubber pad 406 buffers the vibration generated during frame testing, reducing the transmission of vibration to the electric push rod 405. A stabilizing frame is also installed on the housing of the electric push rod 405. The rubber gasket 407 and rubber washer 408 prevent the housing of the electric actuator 405 from twisting or deforming due to vibration, thus protecting the normal operation of internal components such as the motor and transmission mechanism. The rubber gasket 408 also buffers the vibration force transmitted from the electric actuator 405, preventing contact between the housing of the electric actuator 405 and the stabilizer 407, which could damage either. Furthermore, the electric actuator 405 is electrically connected to the control terminal. The electric actuator 405, model GM-300, has good rigidity, ensuring that the body of the electric actuator 405 will not be damaged by prolonged vibration.

[0018] A detection device 10 is provided on one side surface of the rear end fixing frame 3, and the top surface of the rear end fixing frame 3 is fixedly connected to the stabilizing block 8, such as Figure 3 As shown, the detection device 10 enables the frame to be inspected, and the detection device 10 is prior art with the same working principle and power connection as prior art.

[0019] Working principle: Before using this positioning device for testing the strength of carbon fiber bicycle frames, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 6As shown, firstly, by setting the mid-end limiting component 4, during the overall frame testing, after the front-end fixing bracket 2 and the rear-end fixing bracket 3 fix the entire frame, the electric push rod 405 is activated via the control terminal. This allows the output end of the electric push rod 405 to drive the elastic rubber pad 406, the load-bearing block 402, and the stabilizing block 8 to rise. After the hole on the stabilizing block 8 aligns with the hole on the frame, the fixing component 9 passes through the hole on the stabilizing block 8 and the frame, thus limiting and fixing the mid-end of the frame. This allows for more precise limiting and fixing, improving the accuracy and stability of the frame position during testing and ensuring the reliability of the test results. Meanwhile, the elastic rubber pad 406 can buffer the vibration force generated during frame testing, reducing the transmission of vibration force to the electric push rod 405. At the same time, the electric push rod 405 housing is also equipped with a stabilizing bracket 407 and a rubber washer 408, which can prevent the electric push rod 405 housing from twisting or deforming due to vibration, thereby protecting the normal operation of internal components such as motor and transmission mechanism. At the same time, the rubber washer 408 can buffer the vibration force transmitted from the electric push rod 405, thereby avoiding contact between the electric push rod 405 housing and the stabilizing bracket 407, which could lead to damage to the electric push rod 405 housing or the stabilizing bracket 407.

[0020] Secondly, by setting the front-end fixing bracket 2 and the rear-end fixing bracket 3, when testing the frame, after measuring the size of the frame, the rear end of the frame is connected and fixed to the rear-end fixing bracket 3. The front end of the frame is placed on the front-end fixing bracket 2, and the limiting device on the T-block 6 is removed, allowing the connecting block 7, the stabilizing block 8, and the fixing member 9 to move. After the connecting block 7, the stabilizing block 8, and the fixing member 9 move to the appropriate position, the limiting device limits the T-block 6, thereby stabilizing the connecting block 7, the stabilizing block 8, and the fixing member 9, so that the front end of the frame can be connected to the front-end fixing bracket 2. Then, the middle limiting component 4 limits and fixes the middle of the frame. Finally, the detection device 10 is used to detect the entire frame.

[0021] 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.
