Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, and more specifically, to a bicycle frame drilling device. Background Technology

[0002] A bicycle, also known as a pedal bike or cyclist, is typically a small, two-wheeled land vehicle. Riders power it by pedaling, making it a green and environmentally friendly mode of transportation. The manufacturing process of a bicycle's front fork involves drilling holes in the fork structure.

[0003] Chinese patent publication CN202322705452.7, entitled "A Drilling Device for Processing Electric Bicycle Frames," describes a drilling device for processing electric bicycle frames, comprising: a base plate, horizontally placed; a placement platform fixed above the base plate, the placement platform having a groove for holding a front fork workpiece and a pressure plate for pressing down and fixing the front fork workpiece; a Y-shaped track groove at the bottom of the placement platform, the Y-shaped track groove consisting of a main groove and two auxiliary grooves, a sliding column slidably disposed within the Y-shaped track groove; and a sliding seat horizontally slidably mounted on the base plate along the X-axis. This invention enables drilling of one upper branch and two lower branches of a front fork workpiece, and when switching drilling positions, it is not necessary to adjust the front fork position. The device allows for disassembly and repositioning of the fork components. For the front fork components, only one installation and disassembly are required to complete all drilling operations, saving time and effort, offering simple operation, high efficiency, and minimal limitations. However, certain problems remain. While the device controls the sliding column to enter different slots via a rotating guide plate to switch drilling positions, the rotation of the guide plate requires manual operation using a joystick. This cannot be automated with the movement of the sliding seat and the operation of the drilling components. In mass production, manual intervention is required every time the drilling position is switched, increasing labor costs and potentially reducing processing efficiency due to inconsistent operating rhythms. Furthermore, manual operation carries the risk of error, which may affect the accuracy of the drilling position. Therefore, we provide a bicycle frame drilling device. Utility Model Content

[0004] The purpose of this utility model is to provide a bicycle frame drilling device to solve the problems mentioned in the background art above:

[0005] Some existing bicycle frame drilling devices control the sliding column to enter different slots by rotating the guide plate to achieve the switching of drilling positions. However, the rotation of the guide plate needs to be manually completed by the operator with the help of a joystick, which cannot be automatically linked with the movement of the sliding seat and the operation of the drilling components. In mass production, manual intervention is required every time the drilling position is switched, which not only increases labor costs, but may also reduce processing efficiency due to inconsistent operation rhythm. In addition, manual operation is subject to error risk, which may affect the accuracy of drilling position.

At this time, after the drive motor 15 stops, the drill bit 20 will be located above the other branch of the fork workpiece. The cylinder 18 is started again to perform drilling. After all drilling is completed, the drive motor 15 is controlled to drive the lead screw 16 to reverse to reset the whole system. There is no need for manual switching of the drilling position, which has a higher degree of automation, is conducive to mass production, avoids errors caused by manual operation, and ensures the accuracy of the drilling position.
