Description

Technical Field

[0001] The present invention relates to the technical field of bicycle front fork processing equipment, and particularly relates to a milling groove device for processing bicycle front forks. Background Art

[0002] In the structure of a bicycle, the front fork is one of the core components and is located at the front of the vehicle body, undertaking the dual functions of steering and load-bearing support; its upper end is precisely connected to the handlebar component through a headset, and its lower end forms a linkage structure with the wheel assembly through a front axle, and is integrally rigidly fixed through the front tube of the frame, jointly constituting the steering and guiding system of the bicycle; the main structure of the front fork usually consists of an upper tube (also known as a straight tube) and two symmetric left and right front fork arms. For bicycle models equipped with a basket, a special connection structure needs to be designed on the upper tube of the front fork; specifically, milling grooves of specific specifications (such as dovetail grooves or T-shaped grooves) need to be processed on the surface of the upper tube, and the basket is stably installed by embedding matching connectors; to meet such processing requirements, a milling groove device for processing bicycle front forks is proposed herein.

[0003] Regarding the existing milling groove devices for processing bicycle front forks, during the milling groove operation, the positioning and fixing methods for the front fork are relatively traditional and single, and often require manual assistance for positioning. This not only makes the operation cumbersome and inefficient, but also difficult to guarantee the positioning accuracy, resulting in the front fork being prone to shaking during milling, seriously affecting the quality and effect of milling, and leading to a high defective rate of products. In the unloading link, most use manual unloading methods, or the unloading structure is not reasonably designed, resulting in an unsmooth unloading process, prone to problems such as jamming and incomplete unloading, further affecting production efficiency, and increasing labor costs and equipment maintenance costs.
