Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to an automatic drilling and tapping mechanism for a motorcycle steering column connecting plate. Background Art

[0002] In the field of mechanical processing, drilling and tapping materials typically require a traditional single-drill operation. This operation is not only inefficient and time-consuming, but also has significant quality fluctuations. For workpieces requiring multiple holes, this process must be repeated multiple times, which is time-consuming and labor-intensive, and may even result in slight variations in the hole spacing between the workpieces. Therefore, an automated drilling and tapping mechanism incorporating a multi-axis device has been proposed to improve work efficiency and ensure accurate drilling and tapping positions. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a high-efficiency and high-precision automatic drilling and tapping mechanism for a motorcycle steering column connecting plate.

[0004] Its technical solution is as follows: an automatic drilling and tapping mechanism, the main points of which are that it includes a mounting shell, a motor is fixed on the mounting shell, the output shaft of the motor extends into the mounting shell, a driving gear is fixed on the output shaft of the motor, at least one first driven gear is installed in the mounting shell, the first driven gear is installed along the circumference of the driving gear and is respectively meshed with the driving gear, each of the first driven gears is connected to the second driven gear through a transition gear, the rotating shafts of the first driven gear and the second driven gear both extend out of the mounting shell, and a drill bit is connected to the protruding end of the rotating shaft through a connecting piece. With the above structure, the driving gear and the driven gear are densely and reasonably arranged in a limited space, so that the drill bit connected below can be aligned with the corresponding position of the workpiece, and multiple drill bits can be rotated simultaneously, thereby improving efficiency and accuracy. Providing a protective cover on the drill bit can increase the service life of the drill bit, and the detachable drill bit can be replaced with a tap for tapping.

[0005] Preferably, the motor is a servo motor. With the above structure, high-precision control can be achieved, with good stability and low energy consumption.

[0006] Preferably, a protective sleeve is fixed to the lower part of the connecting piece, and the protective sleeve is fixedly covered on the outside of the drill bit. With the above structure, the protective sleeve can protect the drill bit itself from damage and extend its service life. It is also to protect the operator from injury and improve work safety.

[0007] Preferably, the upper portion of the connector has a downwardly extending square connection hole, into which the lower portion of the rotating shaft extends. The lower portion of the connector is hollow, into which the upper portion of the drill bit extends. This structure enables connection between the rotating shaft on the driven gear and the drill bit, achieving synchronized rotation between the rotating shaft and the drill bit.

[0008] Preferably, a through hole is formed on the outer wall of the connector, extending through the lower hollow structure of the connector. At least one pin hole is formed at the insertion end of the drill bit, and a connecting pin is inserted through the through hole and the corresponding pin hole. With this structure, the drill bit length can be adjusted according to the specific workpiece, and the connecting pin ensures a secure connection, preventing the drill bit from falling off during operation.

[0009] Preferably, the transition gear includes an upper transition gear and a lower transition gear fixed to the intermediate shaft. The upper transition gear meshes with the second driven gear, and the lower transition gear meshes with the first driven gear. With this structure, the first and second transition gears rotate in the same direction, ensuring that the first and second driven gears rotate in the same direction, thereby achieving consistent rotation direction and speed of the drill bit, increasing strength, and fully utilizing the internal space of the housing.

[0010] Compared with the existing technology, the beneficial effects of the utility model are as follows: the rotation of the driving gear is realized by the servo motor in a limited space, which further drives the driven gear to rotate, thereby realizing the simultaneous rotation of the drill bit connected to the lower end, which can align with the corresponding position of the workpiece, improve efficiency and accuracy, and arranging a protective cover for the drill bit can increase the service life of the drill bit. The detachable drill bit can be replaced with a tap for tapping, and the length of the drill bit can be reasonably adjusted according to the conditions of the workpiece.
