The existing motorcycle handlebar tube connecting seat locking hole machining method adopts a bolt to clamp the connecting seat on a vertically placed base plate through the direction column hole, and then a drilling machine is used to drill and tap the locking hole. Obviously, this clamping method needs to unscrew the bolt every time the connecting seat blank is placed, and then the bolt is tightened after the connecting seat blank is placed. This process is time-consuming and laborious, and affects the machining efficiency. In addition, the opening of the locking hole is inclined, and the inclination is large. When the drill bit contacts the opening of the locking hole, it is easy to slip, causing the axis of the locking hole to deform, or the opening of the locking hole to be scratched, thereby it is difficult to ensure the machining quality. Obviously, the existing motorcycle handlebar tube connecting seat locking hole machining method has the problems of time-consuming and laborious, low machining efficiency and difficult to ensure the machining quality.
