[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides Figure 1-3 The one-time formed drilling and reaming alloy tool shown includes a shank 1, the outer wall of which is provided with an alloy blade 6 for drilling and reaming, one side of the alloy blade 6 is provided with a cutter head 2 for mounting the alloy blade 6, and one side of the cutter head 2 is provided with a connecting component for connecting to the shank 1.

[0019] Specifically, one side of the alloy blade 6 is fixedly connected to one side of the cutter head 2, and the connecting assembly includes a screw 8. The cutter head 2 is fixedly connected to the side of the handle 1 with a mounting block 7 for inserting the screw 8. The outer wall of the handle 1 is provided with a slot for inserting the mounting block 7. The bottom end of the mounting block 7 is provided with a circular groove. The top of the inner wall of the circular groove is provided with a first thread groove for threadedly inserting the screw 8. The top of the inner wall of the slot is provided with a second thread groove. The screw 8 is threadedly inserted and connected with the second thread groove. The bottom end of the screw 8 is fixedly connected with a nut 9 for extruding the mounting block 7.

[0020] Furthermore, the alloy blade 6 is arranged on the side of the cutter head 2 away from the chip groove 5, the alloy blade 6 and the cutter head 2 are fixedly connected by welding, and a plurality of cutter heads 2 are arranged at equal intervals in a ring shape on the outer wall of the shank 1, and the number of cutter heads 2 corresponds to the number of alloy blades 6 one by one. Through the connecting assembly, after one of the alloy blades 6 is worn, it can be disassembled separately and replaced with a new alloy blade 6, thereby avoiding the waste caused by the scrapping of the entire tool. The size of the mounting block 7 matches the size of the slot, the size of the circular slot is 1.02 times the size of the nut 9, the nut 9 is used to insert the hexagonal bolt, the nut 9 and the screw rod 8 form a bolt, and the bottom end of the screw rod 8 is connected to the top end of the nut 9 The fixed connection is performed by welding, by inserting the hexagonal bolt into the nut 9, and by rotating the nut 9 to drive the screw 8 to rotate synchronously, the threads of the inner walls of the first thread groove and the second thread groove are meshed with the threads of the outer wall of the screw 8, and the diameters of the first thread groove and the second thread groove are the same, and the screw 8 is connected by inserting the first thread groove and the second thread groove, and under the extrusion of the nut 9 and the top of the inner wall of the circular groove, the mounting block 7 and the tool handle 1 are firmly connected. When the alloy blade 6 needs to be replaced, the screw 8 is removed from the second thread groove by rotating the nut 9, and the connection between the mounting block 7 and the tool handle 1 can be released, thereby separating the cutter head 2 from the tool handle 1, and replacing the alloy blade 6.

[0021] Specifically, a concave surface 3 is provided on the top of the cutter head 2, a bevel 4 for guiding materials is provided on one side of the top of the cutter head 2, a chip groove 5 for chip removal is provided on the side of the cutter head 2 away from the alloy blade 6, and the thickness of the top of the alloy blade 6 is 0.3 mm.

[0022] Furthermore, the alloy blade 6 is made of alloy material, which has the characteristics of high hardness, high wear resistance, high elastic modulus, small thermal expansion coefficient, sharp cutting edge, good performance, fast cutting speed, long service life and effective reduction of blade replacement frequency. When the alloy blade 6 cuts the workpiece, the chips will pass through the three bevels 4 of the concave surface and finally be removed by the chip groove 5, thereby avoiding the accumulation of chips on the processed surface during processing and causing damage to the processed surface. The top section thickness of the alloy blade 6 is 0.3mm, and the end face is not a conventional completely flat surface, which facilitates the drilling of the workpiece. Therefore, during the production and processing process, the side blade size of the alloy blade 6 can be ground according to the product diameter size, and the product can be directly reamed after drilling, reducing the secondary clamping, tool changing, and sequence conversion time, thereby ensuring product accuracy.
