Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically a spoke installation strength testing device. Background Technology

[0002] Spokes are an important component of bicycles, connecting the rim and hub. They not only support the wheel but also ensure its stability and durability.

[0003] Existing spokes are usually made of metal or carbon fiber. Unlike the processing technology of metal spokes, carbon fiber spokes are produced by heating and molding carbon fiber prepreg. When installing terminals at both ends of the spokes, a tensile testing machine is required to ensure that the terminals are installed firmly. At the same time, the tensile strength of the spokes must be tested before it can leave the factory.

[0004] However, when performing spoke installation strength tests on existing tensile testing machines, in order to ensure the installation strength of the bottom fixing clamp, the clamps at both ends of the spoke must be removed before the spoke can be reinstalled, which causes inconvenience in operation during strength testing.

[0005] Based on this, the present invention designs a spoke installation strength testing device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a spoke installation strength testing device to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: It includes a frame and a hydraulic drive device fixedly mounted on the frame. A force gauge is fixedly mounted on the output end of the hydraulic drive device, and a mounting bracket is fixedly mounted on the output end of the force gauge. An upper clamping plate is hinged to the mounting bracket, and an upper placement groove is formed on the upper clamping plate. A lower clamping plate is fixedly mounted on the frame, and a lower placement groove is formed on the lower clamping plate. A spring is fixedly mounted on the frame, and a swing block is fixedly mounted on the other end of the spring. A limiting block corresponding to the lower placement groove is fixedly mounted on the swing block, and an extension plate is fixedly mounted on the swing block.

[0008] Preferably, a limiting groove is provided on the upper clamping plate, and a limiting plate is rotatably disposed in the limiting groove.

[0009] Preferably, an auxiliary plate is fixedly provided on the limiting plate, and the auxiliary plate is located at the end of the limiting plate away from the upper clamping plate.

[0010] Preferably, a reinforcing plate is fixedly provided on the lower clamping plate, and the other end of the reinforcing plate is fixedly provided on the frame.

[0011] Preferably, there are two reinforcing plates, and the swing block is located between the two reinforcing plates.

[0012] Preferably, the swing block has a clearance hole, and a support platform is fixedly installed in the clearance hole.

[0013] In summary, this application has the following beneficial technical effects: by setting up the upper clamping plate and the lower clamping plate, during the spoke installation strength test, stepping on the extension plate causes the limiting block to disengage from the lower clamping plate, allowing the terminal to be placed in the lower placement slot. After placing the other end of the terminal in the upper placement slot, the test can begin after being restricted by the limiting plate. This has the advantage of simplifying the operation difficulty during strength testing. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0023] A spoke mounting strength testing device includes a frame 1 and a hydraulic drive device 2 fixedly mounted on the frame 1.

[0024] A force gauge 3 is fixedly installed on the output end of the hydraulic drive device 2. A mounting bracket 4 is fixedly installed on the output end of the force gauge 3. An upper clamping plate 5 is hinged on the mounting bracket 4. An upper placement groove 6 is opened on the upper clamping plate 5. A limit groove 7 is opened on the upper clamping plate 5. A limit plate 8 is rotatably installed in the limit groove 7. An auxiliary plate 9 is fixedly installed on the limit plate 8. The auxiliary plate 9 is located on the limit plate 8 at the end away from the upper clamping plate 5.

[0025] A lower clamping plate 10 is fixedly installed on the frame 1. A lower placement groove 11 is opened on the lower clamping plate 10. A reinforcing plate 12 is fixedly installed on the lower clamping plate 10. The other end of the reinforcing plate 12 is fixedly installed on the frame 1. There are two reinforcing plates 12.

[0026] A spring 13 is fixedly installed on the frame 1, and a swing block 14 is fixedly installed on the other end of the spring 13. The swing block 14 is located between two reinforcing plates 12. A limiting block 15 corresponding to the lower placement groove 11 is fixedly installed on the swing block 14, and an extension plate 16 is fixedly installed on the swing block 14. A clearance hole 17 is opened on the swing block 14, and a support platform 18 is fixedly installed in the clearance hole 17.

[0027] The implementation principle of this embodiment is as follows: During the spoke installation strength test, the swing block 14 is tilted by stepping on the extension plate 16, compressing the spring 13. At this time, the swing block 14 disengages from the lower clamping plate 10, and the limiting block 15 disengages from the lower placement groove 11. Then, the terminal of any end of the spoke is placed on the support platform 18. Then, the restriction on the extension plate 16 is released, so that when the spring 13 returns to its original position, the swing block 14 abuts against the lower clamping plate 10, and the limiting block 15 abuts against the lower placement groove 11. Then, the position of the output end of the hydraulic drive device 2 is adjusted so that the spoke... The terminal at the other end can be placed in the upper placement slot 6. Then, the auxiliary plate 9 is manually moved so that the limiting plate 8 is placed in the limiting slot 7, which limits the terminal of the spoke, and the test can begin. When the test is completed, the position of the output end of the hydraulic drive device 2 is adjusted first. Then, the auxiliary plate 9 is moved so that the limiting plate 8 is disengaged from the limiting slot 7, and the terminal can be taken out from the upper placement slot 6. Then, by stepping on the extension plate 16, the swing block 14 is disengaged from the lower clamping plate 10, and the terminal can be taken out from the lower placement slot 11. Then, the spoke to be tested is reinstalled.

[0028] By setting up the upper clamping plate 5 and the lower clamping plate 10, during the spoke installation strength test, stepping on the extension plate 16 causes the limiting block 15 to disengage from the lower clamping plate 10, allowing the terminal to be placed in the lower placement slot 11. Then, the other terminal is placed in the upper placement slot 6, and the test can begin after being restricted by the limiting plate 8. This has the advantage of simplifying the operation difficulty during strength testing.
