Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present utility model.
The utility model is described in further detail below with reference to fig. 1 and 2:
referring to fig. 1, the drill bit for the radial drilling machine comprises a drill bit main body 1, a drill bit 4 is arranged at the free end of the drill bit main body 1, chip grooves 2 and polishing mechanisms 3 are arranged on the drill bit main body 1, the chip grooves 2 and the polishing mechanisms 3 are arranged on the drill bit main body 1 at intervals in a spiral mode, and the polishing mechanisms 3 are abrasive particles inlaid on the outer surface of the drill bit main body 1. The drill bit is in the in-process of drilling, and is drilling, simultaneously through grinding mechanism 3 polishes the inner wall in hole for after the drilling is accomplished, also accomplish the polishing of hole, follow-up no longer need carry out solitary polishing, if the diameter of drilling is than less moreover, follow-up inconvenient polishing to the inner wall in hole has promoted the quality of drilling effectively, has promoted production efficiency simultaneously.
The drill body 1 is a cylinder, the free end of the drill body is conical, and the drill blade 4 is embedded in the free end of the drill body 1 and tangent to the conical surface of the free end. The chip grooves 2 are spiral, the polishing mechanism 3 is abrasive particles embedded on the outer surface of the drill bit body 1, the abrasive particles are diamond abrasive particles, and the diamond abrasive particles are uniformly embedded on the outer surface of the drill bit body 1 and slightly protrude to the outer surface. When the drill bit is used for drilling, chips in the drilling can be discharged outwards along the chip removal groove 2, so that the phenomenon that the chips are blocked is avoided, and the working efficiency of the radial drilling machine for drilling is improved. The diamond abrasive particles are small in size and small in protruding degree, so that when the diamond abrasive particles are used for polishing the inner wall of a hole, the inner wall of the hole is only polished smoothly, the hole is smooth, the diameter of the drilled hole cannot be enlarged, and the size precision of the drilled hole of the drill bit is guaranteed.
The stiff end of drill bit body 1 is equipped with installation department 5, installation department 5 is kept away from the one end of drill bit body 1 is equipped with connecting piece 6, drill bit body 1 installation department 5 is in radial drill through installation department 5 and connecting piece 6 fixed mounting.
