Description

Technical Field

[0001] This invention relates to the field of frame strength testing technology, and in particular to a titanium alloy bicycle frame strength testing device. Background Technology

[0002] In the production process of titanium alloy bicycle frames, strength testing is generally required to check whether the frame quality is up to standard. The core purpose of strength testing is to verify its structural safety and reliability. By simulating various load conditions in actual riding, the mechanical properties of the frame under static and fatigue conditions can be evaluated to ensure that it can withstand the impact and cyclic stress during use. This effectively avoids frame failure caused by potential material defects, process flaws, or design deficiencies, thereby ensuring the rider's safety and extending the product's service life.

[0003] Existing bicycle frame strength testing equipment typically uses rigid clamps to hold the bicycle frame. While this method provides a more secure grip, it easily damages the surface coating of the frame. Excessive clamping force can also impair the material properties of the frame. Other existing equipment usually applies longitudinal pressure to the frame using a compression device after clamping. While simple and reliable, this method cannot simulate horizontal or tilting bending of the frame. Current technologies generally only compress and bend the frame, often neglecting the pedaling force at the bottom bracket, thus failing to simulate pedaling force. Therefore, a titanium alloy bicycle frame strength testing device is needed that can flexibly clamp the frame, simulate horizontal and tilting bending, and simulate pedaling force to address the shortcomings of existing titanium alloy bicycle frame strength testing equipment.

(3) After the bicycle frame is clamped, the bidirectional synchronous motor on the transmission assembly drives the first crank plate and the second crank plate to rotate synchronously in the same direction. Then the first crank plate will drive a third crank plate to rotate synchronously through the third connecting rod.

[0040] like Figure 11 As shown, in the positioning assembly 410, the positioning chassis 417 is fixedly installed at the output end of the second hydraulic push rod 412 and the output end of the third hydraulic push rod 413; the flexible protrusion 418 is fixedly installed at the front end of the hemispherical clamp 419; the hemispherical clamp 419 is rotatably installed inside the rolling base 420; the rolling base 420 is fixedly installed at the front end of the positioning chassis 417; the flexible chassis 421 is fixedly installed at the front end of the central positioning plate 422; the central positioning plate 422 is fixedly installed at the front end of the positioning chassis 417.

[0043] Working principle of the invention: Figure 1 and Figure 2The invention provides a usage method and corresponding scenario. The attitude control of the bicycle frame strength testing process is determined by the support device 1, the clamping device 4, and the positioning device 5. The attitude of the support device 1 is determined by the clamping device 4, and the attitude of the positioning device 5 is determined by the clamping device 4. The clamping device 4 is the core of the bicycle frame strength testing process.

[0044] Taking a preferred embodiment as an example, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the control host 201 and control button panel 202 on the control device 2 send commands to the first linear motor 106 and the second linear motor 107, causing the first linear motor 106 and the second linear motor 107 to move laterally together. The first linear motor 106 and the second linear motor 107 drive the linkage bracket 109 and the linkage plate 110 on the pressurizing assembly 104 to move laterally together. Subsequently, the linkage plate 110 drives the pressurizing cylinder 115 and the pressurizing plunger plate 116 to move laterally, thereby adjusting the pressurizing position of the pressurizing plunger plate 116. When the pressure plunger disc 116 reaches the designated position, the hydraulic oil tank 204 inside the control housing 203 drives hydraulic oil into the pressure cylinder 115 via the oil pump. The hydraulic oil then drives the pressure plunger disc 116 to slide downwards, causing the horizontal plane at the lower end of the pressure plunger disc 116 to contact the upper end of the frame, thus achieving vertical pressure. When the second linear motor 107 remains stationary, the first linear motor 106 inside the support device 1 slides laterally within the support rail 108. The first linear motor 106 drives the linkage bracket 109 in a linked manner. The lower end of disc 110 slides laterally. The linkage bracket 109, via the first connecting rod 111, drives the pressure slider 112 to slide horizontally. Simultaneously, the linkage bracket 109, via the second connecting rod 113, drives the electromagnet 114 to slide horizontally. Subsequently, the pressure slider 112 drives the pressure cylinder 115 and the pressure plunger disc 116 to slide horizontally, causing the inclined surface of the lower end of the pressure plunger disc 116 to align with the upper end of the bicycle frame. Then, the hydraulic oil in the pressure cylinder 115 drives the pressure plunger disc 116 downwards, causing the pressure plunger disc 116 to... The inclined surface applies oblique pressure to the frame, thereby achieving the oblique deflection function; when the pressure slider 112 stops moving, the electromagnet 114 will be energized and generate magnetic force, so that the electromagnet 114 and the linkage plate 110 are magnetically attracted and fixed, thereby achieving the locking function of the pressure slider 112; the magnetic base 105 on the support base 102 attracts the clamping base 408 by magnetic force; the cover body 301 of the protective cover 3 is slidably installed at the front end of the support shell 101 in the lateral direction; the observation hole 302 is used to observe the internal condition of the support shell 101.

[0045] like Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, the first hydraulic push rod 103 on the support device 1 extends forward, driving the first clamping base 403, the second clamping base 405, and the third clamping base 407 to move forward. When the first clamping base 403 and the third clamping base 407 slide towards the first fixed base 402 and the third fixed base 406 at the upper end of the clamping base 408, the first clamping base 403 and the third clamping base 407 will drive the second hydraulic push rod 412 of the offset assembly 401 to tighten inward towards the third hydraulic push rod 413. Subsequently, the second hydraulic push rod 412 and the third hydraulic push rod 413 drive the two locking positions. The components 410 move closer together, causing the flexible protrusions 418 on the surface of the hemispherical clamp 419 to first contact the side of the frame. The flexible protrusions 418 are then deformed by compression, transferring the compressive force to the hemispherical clamp 419. This causes the hemispherical clamp 419 to deflect and roll within the rolling base 420. Simultaneously, the flexible chassis 421 deforms upon contact with the frame surface, achieving adaptive contact with the frame surface and thus realizing the flexible clamping function of the bicycle frame. After the bicycle frame is clamped, the hydraulic pump 415 drives the hydraulic oil in the hydraulic tank 416 into the first oil delivery hose 411, and then... Hydraulic oil enters the second hydraulic push rod 412 through pipe 411, while hydraulic oil in the third hydraulic push rod 413 flows back from the second oil supply hose 414 to the hydraulic tank 416. At this time, the output end of the second hydraulic push rod 412 extends outward, while the output end of the third hydraulic push rod 413 retracts inward, causing the offset component 401 to drive the two locking components 410 to slide in the same direction. The two locking components 410 drive the bicycle frame to bend to one side, thereby realizing the horizontal bending function of the bicycle frame. After the bicycle frame is clamped, the bidirectional synchronous motor 425 on the transmission component 409 drives the first crank 424 and the second crank. The first crank disc 426 rotates synchronously in the same direction. Then, the first crank disc 424 drives a third crank disc 501 to rotate synchronously through the third connecting rod 423. The second crank disc 426 drives another third crank disc 501 to rotate synchronously through the fourth connecting rod 427. Then, the third crank disc 501 drives the gear at the bottom bracket of the frame to rotate through the positioning shaft 502 and the positioning joint 504, thereby applying pedaling force to the bottom bracket of the frame. The positioning bushing 503 is fixedly installed inside the second fixed base 404 and the second clamping base 405 respectively. The clamping base 417 and the center positioning disc 422 are used for rigid support and positioning during the clamping process.
