Description

Technical Field

[0001] The utility model relates to the technical field of radial drilling machine equipment, in particular to a radial drilling head structure used for mechanical processing. Background Art

[0002] A radial drilling machine is a drilling machine with a rocker arm that can rotate and rise and fall around a column. Usually, the spindle box moves horizontally on the rocker arm and rotates around the column with the rocker arm. According to the clamping structure of the machine tool, radial drilling can be divided into hydraulic radial drilling machines and mechanical radial drilling machines. Among all types of drilling machines, radial drilling machines are easy to operate, flexible, and have a wide range of applications. They are typical and are particularly suitable for hole processing of single or batch production of large parts with multiple holes. They are common machine tools in general machining workshops.

[0003] Radial drill bits are tools used in radial drilling machines to drill through holes or blind holes in solid materials and expand existing holes. Commonly used drill bits include twist drills, flat drills, center drills, deep hole drills and trepanning drills.

[0004] A Chinese patent publication (publication number: CN220178254U) discloses a drill bit for a radial drilling machine, which includes a drill bit body, a chip removal groove is provided on the drill bit body, and a grinding mechanism is provided on the outer surface of the drill bit body. The grinding mechanism enables the drill bit to grind the inner wall of the drilled hole while drilling during the drilling process. When the drilling is completed, the grinding is also completed, so that the inner wall of the drilled hole is smoother, and the drilling quality is improved. The drill bit for a radial drilling machine provided by the utility model has a very simple structure, but the drilling quality is very high. The drilling quality is greatly improved through the low-cost drill bit design. However, in actual use, the spiral hollow in the drill bit conveys coolant for cooling, which reduces the strength of the drill bit, making the drill bit easy to break, and the temperature of the drill bit cannot be detected. If the drill bit is overheated and the heat dissipation is not discovered in time, continued use is likely to cause damage to the drill bit, which is not conducive to the installation and use of the radial drill. For this reason, a radial drill bit structure for mechanical processing is proposed. Utility Model Content
