Drilling and tapping machine

The utility model relates to a drilling and tapping machine, in particular to the technical field of tapping machines. Comprising a bottom plate, a machining table, a fixed mounting plate, a servo motor, a screw rod, a sleeve, a clamping plate, a transmission assembly, a mounting block, a scrap removing mechanism, a supporting column, a rotating disc, a rocker arm, a driving motor, a drill bit and a cooling assembly. The problems that in the drilling process, a large number of sweeps are generated after the position used for clamping the workpiece to be machined is drilled, and if the sweeps are not cleaned, the drilling and tapping precision of the next time is affected are solved. And the problem that the drill bit deforms due to the fact that the temperature of the drill bit rises when the drill bit drills holes in a high-speed rotating state is solved. 本实用新型涉及一种钻孔攻丝机，特别涉及攻丝机的技术领域。包括底板、加工台、固定安装板、伺服电机、螺杆、套筒、夹持板、传动组件、安装块、除屑机构、支撑柱、转盘、摇臂、驱动电机、钻头、降温组件。克服了在钻孔的过程中，用于夹持代加工件的位置进行钻孔后会产生大量的废屑，如果不清理就会影响下一次的钻孔攻丝精准度的问题；
