Description
Technical Field
[0001] The utility model relates to the technical field related to bicycle shock absorbers, in particular to a production shaking detection mechanism for a bicycle shock-absorbing front fork. Background Art
[0002] Bicycle shock absorbers are used to detect the shaking of bicycle shock-absorbing front forks during the production process. They can quickly detect the shaking amount between the inner and outer tubes of the shock-absorbing front fork. Its upper end is connected to the handlebar assembly, the frame assembly cooperates with the front tube, and the lower end cooperates with the front axle assembly to form the steering system of the bicycle. By turning the handlebar and the front fork, the front wheel can change direction, thus guiding the bicycle. In addition, it can also control the driving of the bicycle. The force condition of the front fork assembly is that of a cantilever beam, so the front fork assembly must have sufficient strength and other properties. It is the spring with the longest application history and is also the most common type. The hardness of the spring, the so-called elastic coefficient, represents the ratio of the force to the degree of deformation. Under the principle of not exceeding the load, the elastic coefficient of a simple coil spring is fixed under different stress states and will not be affected by the ambient temperature. After painting or lubrication, the stability and durability are very high. However, the only disadvantage of the coil spring is its weight. Therefore, more advanced front forks have begun to use lighter but more expensive titanium alloy springs. During the inspection process, they can only be judged based on the workers' experience or visual inspection, which is prone to accidents such as missed inspections or wrong inspections, resulting in front forks with quality problems leaving the factory, posing a safety hazard to cyclists. Therefore, there is a special need for a shaking detection mechanism for the production of bicycle shock-absorbing front forks.
[0003] However, during the inspection process of the existing bicycle shock absorber front fork production shake detection mechanism, some shock absorber front forks do not detect the shake of the inner and outer tubes during the production process or simply conduct a manual inspection, and there is no quantitative measurement of the shake amplitude of the shock absorber front fork. Manual inspection results in inaccurate detection data, which affects the detection efficiency. Utility Model Content
