[0024] It should be noted that, since the existing radial drilling machine mostly only has the ability of drilling straight holes, it is difficult to expand the straight holes on the mold, the use is limited, and after the drilling is completed, the mold needs to be disassembled and transported to other equipment with the ability of hole expansion, which increases the complexity of operation and reduces the mold processing efficiency. The embodiment can expand the concave hole with different inner radii by accurately controlling the depth of the milling cutter 12 in the mold hole, and the inner side wall of the hole can be axially cut by the axial movement of the milling cutter 12 in the mold hole to achieve the purpose of hole expansion.

When drilling and expanding holes on the mold, the drill bit and the milling cutter 12 can be disassembled and replaced, and the mold on the radial drilling machine 1 does not need to be disassembled and transported, thereby improving the convenience of processing and improving the efficiency.

[0025] Specifically, in the embodiment, the scheme mainly includes a moving table 9 and a milling cutter 12. When drilling and expanding holes on the mold, the connecting plate 2 is installed and fixed on the moving end of the radial drilling machine 1, one end of the rotating rod 11 is installed on the drill bit, the drill bit is used to drill holes on the mold, then the milling cutter 12 with the same inner diameter as the hole is replaced, at this time, the micro pneumatic cylinder 17 drives the distance measuring block 18 to move through the output end on one side, the distance measuring block 18 moves in the groove 16, and the distance measuring value of the distance measuring sensor 15 changes. At this time, the distance measuring block 18 is adjusted to the same vertical plane as the outer side wall of the milling cutter 12 according to the value change, the milling cutter 12 is inserted into the hole, the three-phase motor 6 drives the ball screw 7 to rotate through the output end on one side, the moving table 9 on the ball screw 7 moves linearly along the guide rod 8, the milling cutter 12 moves linearly synchronously, the milling cutter 12 contacts the inner side wall of the hole and cuts and expands the hole, and the distance measuring sensor 15 monitors the moving distance of the moving table 9 in real time. When the moving distance reaches the hole expansion radius or the maximum depth distance, the three-phase motor 6 stops rotating. Then, the speed reducer 13 drives the gear 14 to rotate through the output end on one side, the gear ring 4 rotates through the meshing connection between the gear 14 and the gear ring 4, and the support sleeve 5 and the moving table 9 move axially synchronously after the gear ring 4 rotates, and the milling cutter 12 also moves axially. Since the milling cutter 12 is in an eccentric state with the hole, the milling cutter 12 moves axially in the hole to expand the hole at other positions and form a circular hole. After the hole expansion is completed, the milling cutter 12 can be taken out of the hole.

[0029] In the embodiment, the distance between the distance measuring sensor 15 and the distance measuring block 18 can be adjusted by the linear movement of the distance measuring block 18 inside the groove 16, and then the adjustment is made according to the outer diameter of the milling cutter 12, so that the distance measuring block 18 and the outer sidewall of the milling cutter 12 are on the same vertical plane, and finally the linear movement distance of the milling cutter 12 is judged by the difference of the distance measurement, and the inner diameter of the reaming is controlled.
