Description

High-efficient U-shaped drill bit for numerical control lathe Technical Field The utility model relates to the technical field of drill bits, in particular to a high-efficiency U-shaped drill bit for a numerical control lathe. Background The U-shaped drill bit is U-shaped and has two tips, can cut and form holes in the drilling process, is made of a firm metal material, is commonly used for drilling hard materials such as metal, stone and concrete, and has good hardness and wear resistance. Through retrieval, the utility model patent of patent grant publication No. CN221161032U discloses a novel U bit, which comprises a U bit body, wherein a first bit and a second bit are arranged on the U bit body, the first bit is connected with the U bit body through screws, the second bit is also connected with the U bit body through screws, an installation part is arranged on the U bit body, the second bit is closer to the installation part than the first bit, the axle center of the U bit body is used for rotating, and the rotation radius of the second bit is larger than that of the first bit. Above-mentioned U type drill bit can accomplish rough machining and finish machining operation in step in pore, but along with the extension of live time, when first tool bit and second tool bit need be changed because of wearing and tearing, operating personnel at first need take off two tool bit bolts of fixed first tool bit and second tool bit in order to relieve the fixed of first tool bit and second tool bit, later change new first tool bit and second tool bit and reset two tool bit bolts, in this process, because the tool bit bolt is less, therefore accomodate the degree of difficulty after the dismantlement is great, easily lead to losing, also comparatively inconvenient when follow-up reset alignment simultaneously, there is great influence to the change efficiency of tool bit. Therefore, it is necessary to invent a high-efficiency U-shaped drill for a numerical control lathe to solve the above problems.
