[0002] Drilling refers to the operation of using a drill bit to make a hole in a solid material. When drilling annular metal workpieces, a drilling machine is often needed to drill the surface of the workpiece.

[0003] The existing drilling machines have multiple single-axis drilling machines, which drill holes by manually moving the workpiece to the bottom of the drill bit and manually adjusting the drill bit position. When multiple holes need to be drilled on the surface of the workpiece, the workpiece is often moved and rotated one by one by manual control, and the rotation position is adjusted to achieve multiple consecutive drilling processes. Not only are there many steps and the drilling efficiency is low, but each process also requires re-positioning. After multiple positioning, the drilling position often deviates, resulting in inaccurate drilling positions, which brings inconvenience to production. Therefore, a synchronous multi-axis drilling machine is proposed. Utility Model Content

[0029] As attached Figure 1 、 5 As shown, there are six stabilizing cylinders 6, and every three stabilizing cylinders 6 are distributed in a ring shape. There are six guide connecting rods 9, and every three guide connecting rods 9 are distributed in a ring shape on the outside of the three stabilizing cylinders 6. The three stabilizing cylinders 6 form a work station, and the aluminum mold 10 of the work station is supported and positioned by the guide connecting rods 9.

[0030] As attached Figure 1 、 3As shown, the bottom end of every three guide connecting rods 9 passes through the middle of an aluminum mold 10, and a stopper 12 is provided at the bottom of the guide connecting rod 9. A rivet is inserted in the middle of the stopper 12. The stopper 12 is provided at the bottom of the aluminum mold 10, and the spring 11 is provided at the top of the aluminum mold 10.

[0034] The working principle of the utility model is as follows: when in use, the annular workpiece is sleeved on the middle part of the stabilizing rod 19, and the annular workpiece is limited by the stabilizing rod 19. When it is necessary to drill a hole on the surface of the annular workpiece, the servo motor 23 is started to control the workpiece to move to the position directly below the drilling station, and then the lifting frame 2 is controlled to sequentially drive the aluminum mold 10 to move downward until the stabilizing rod 19 is inserted into the interior of the positioning hole 13, so that the aluminum mold 10 squeezes the workpiece. At this time, the aluminum mold 10 squeezes the spring 11, so that one end of the drill bit 8 can be moved out from the interior of the through hole 14 until the drill bit 8 contacts the surface of the workpiece.

[0035] Then start the driving motor to control the rotating rod 7 in turn to drive the drill bit 8 to rotate, and at the same time cooperate with the lifting frame 2 to move downward, so that synchronous multi-axis drilling can be achieved on the surface of the annular workpiece, thereby improving the processing efficiency;
