[0019] See also Figure 1-3 As shown, a casting drilling device includes a mold cylinder 1, a follower ring block 2, a twist drill rod 4, a suction and discharge pipe 6, a driving gear 7, a first motor 9, a grinding cutter 17, an outward-moving ring block 18, a transmission gear 20 and a twist groove-inserted mold rod 21, the barrel mouth of the mold cylinder 1 is rotatably connected with the follower ring block 2 through a sealing bearing 3, and a rod-penetrating round cover 5 is installed at the top end of the follower ring block 2, the twist groove-inserted mold rods 21 are distributed and installed in the follower ring block 2, and one end of each twist groove-inserted mold rod 21 is located in the twist groove on the twist drill rod 4, one end of the twist groove-inserted mold rod 21 exceeds the bottom surface of the follower ring block 2, and the surrounding space where one end of the twist groove-inserted mold rod 21 is located is the inside of the annular hole of the outward-moving ring block 18; When the bottom end of the twist drill rod 4 passes through the short tube 120 to drill a hole in a workpiece, one end of the rod 21 is inserted into the twist groove on the twist drill rod 4, and the surrounding space where the one end of the rod 21 is inserted into the twist groove is the inside of the annular hole of the outward-moving ring block 18, which prevents the drilled waste from being discharged along the outside of the twist groove, and is conducive to guiding the waste into the outward-moving ring block 18.

[0020] like Figure 2 and Figure 3 As shown, a plurality of grinding cutters 17 are distributed and installed around the inner port of the short tube 120 at the bottom of the mold cylinder 1, a ring baffle 110 is provided in the mold cylinder 1, and a convex ring portion located on one side of the middle hole of the ring baffle 110 is rotatably connected with the ring hole at one end of the outward shifting ring block 18 through a bearing, a gear ring 19 is installed at one end of the outward shifting ring block 18, and the annular surface at the bottom of the outward shifting ring block 18 is close to the grinding cutter 17, the gear ring 19 is transmission-connected with the driving gear 7 through a transmission gear 20, and the shaft end on one side of the driving gear 7 is connected with the first motor 9; When the waste is guided into the outward-moving ring block 18, the first motor 9 is operated to drive the driving gear 7 to rotate, so that the transmission gear 20 and the gear ring 19 connected thereto are in a high-speed rotation state, and further drive the outward-moving ring block 18 to rotate at a high speed relative to the adjacent grinding and cutting knife 17. Combined with the shape and distribution state of the grinding and cutting knife 17, it plays a role in guiding the waste slag to the outside, and at the same time, the large strips of waste are broken into segments again for processing.

[0021] The short tube 120 is not limited to an integrated structure with the mold cylinder 1, but can also be a detachable and replaceable structure with a threaded connection. The inner diameter of the short tube 120 matches the aperture size of the drilled hole, so that it can be selectively used according to actual needs.

[0022] One end of the suction and discharge pipe 6 is connected and installed in the mold cylinder 1, and the middle of the bottom of the mold cylinder 1 is a conical surface, and the other end of the suction and discharge pipe 6 is connected to the input port of the external vacuum cleaner; When the waste fragments processed again fall to the bottom edge of the mold cylinder 1, the external vacuum cleaner can be operated to discharge the waste fragments through the suction and discharge pipe 6, thereby improving the convenience of waste discharge and helping to improve the processing environment.

[0023] The driving gear 7 is rotatably mounted in the rectangular frame 8 , and the frame opening of the rectangular frame 8 and the arc-shaped hole 130 located on the mold cylinder 1 are sealed and fixedly connected to each other.

[0025] The annular surface of the mold cylinder 1 is fixedly mounted with a connecting seat 12, and the connecting seat 12 is connected to the second oil cylinder 15 through the second carrier 13. The cylinder body of the second oil cylinder 15 is mounted at the bottom of one side of the fixed carrier plate 16. When the second oil cylinder 15 is in a telescopic state, it is beneficial to adjust the position height of the mold cylinder 1 to ensure that the bottom end port of the short tube 120 is close to the drilling position of the workpiece.

[0026] Working principle: When the bottom end of the twist drill rod 4 passes through the short tube 120 to drill a workpiece, one end of the rod 21 is inserted into the twist groove on the twist drill rod 4, and the surrounding space where the end of the rod 21 is inserted into the twist groove is the inside of the ring hole of the outward-moving ring block 18, so as to prevent the drilled waste from being discharged along the outside of the twist groove, and at the same time, it is conducive to guiding the waste into the outward-moving ring block 18; When the waste is guided to fall into the outward-moving ring block 18, the first motor 9 is operated to drive the driving gear 7 to rotate, so that the transmission gear 20 and the gear ring 19 connected thereto are in a high-speed rotation state, and further drive the outward-moving ring block 18 to rotate at a high speed relative to the grinding cutter 17 close thereto, and combined with the shape and distribution state of the grinding cutter 17, the waste slag is guided to the outside, and at the same time, the large strips of waste are broken into segments again for processing; When the waste fragments processed again fall to the bottom edge of the mold cylinder 1, the external vacuum cleaner is operated to discharge the waste fragments through the suction and discharge pipe 6, thereby improving the convenience of waste discharge and helping to improve the processing environment; To sum up, compared with the prior art, the difference lies in: adding a twist groove insertion rod 21 that can be placed in the twist groove of the drill rod, and combining with the follower ring block 2 connected to the twist groove insertion rod 21 and rotatably installed in the barrel mouth of the barrel 1 through the sealed bearing 3, which is beneficial to limit the movement of drill slag along the twist groove, ensuring that the drill slag falls into the outward-moving ring block 18, and at the same time, the driven rotating outward-moving ring block 18 and the closely configured grinding and cutting knife 17 can further crush the drill slag, and the collection and treatment are convenient, which prevents the disorderly discharge of large-sized waste. Then, running an external vacuum cleaner can discharge the broken waste through the suction and discharge pipe 6, thereby improving the convenience of waste discharge and helping to improve the processing environment.
