Embodiment Construction
[0016] As shown in the figure, a new type of drill reamer drill tip includes a drill tip 1. The drill tip 1 includes an extension end 2 and an insertion end 3. The insertion end 3 includes a locking end 31 and a transition end 32. With the first positioning end 33, the locking end 31 is provided with an external thread 4, the width R1 of the first positioning end 33 is slightly larger than the width R2 of the locking end 31, and the locking end 31 The width R2 is greater than the width R3 of the transition end 32;
[0017] The length L1 of the transition end 32 is one half of the length L2 of the first positioning end 33, and the length L2 of the first positioning end 33 is one third of the length L3 of the locking end 31;
[0018] The extended end 2 includes a second positioning end 21 and a trimming end 22, the width R4 of the second positioning end 21 is greater than the width R1 of the first positioning end 33, and the width R5 of the trimming end 22 is equal to the first ...

The invention provides a novel drilling reamer drill tip. The novel drilling reamer drill tip comprises a drill tip body, wherein the drill tip body comprises an extending end and an insertion end; the insertion end comprises a locking end, a transition end and a first positioning end; the locking end is provided with an outer thread; a trimming end comprises a blade and a spiral groove; the blade is provided with a round through hole and a groove. The structure is simple, and design is reasonable. The locking end is provided with the outer thread, so that a drilling reamer is convenient to mount and dismount. When the drilling reamer is damaged, only the drill tip of the drilling reamer needs to be replaced simply, conveniently and rapidly, and cost is low. After the drilling reamer is installed through the round through hole in the blade, water flows into the spiral groove through the round through hole and the groove, the cooling function is achieved, and the service life of the drilling reamer drill tip is prolonged. Meanwhile, the first positioning end and a second positioning end in the drill tip are used for positioning multiple times, stress is more uniform in the working process, accuracy is improved, the overall working efficiency is improved, and requirements of manufacturers can be better met.
Description
technical field [0001] The invention relates to the technical field of drill reamers, in particular to a novel drill reamer drill point. Background technique [0002] Drilling reamer with one or more teeth, rotary tool for removing thin layer of metal on the surface of machined hole, rotary finishing tool with straight edge or helical edge, mainly used for reaming or repairing holes. At the same time, the rotary tool used to cut off the thin metal layer on the machined surface of the hole can obtain accurate size and shape after the hole is machined by the reamer. When the existing drill reamer is trimmed, due to the unreasonable design, the drill tip often cracks. The phenomenon affects its accuracy, requires frequent replacement, high cost, affects work efficiency, and cannot meet the needs of manufacturers. Contents of the invention [0003] The problem to be solved by the present invention is to provide a new type of drill reamer drill tip, which solves the problem th...
