Embodiment 1

[0019] like figure 1 As shown, the drill-tapping integrated spiral tap in this example consists of a square connecting tap shank, a spiral tap, and an auger bit. The auger bit has a cutting edge for guiding drilling. Shaped grooves form an integrated flute.

[0020] The cutting edge of the drill-tapping composite spiral tap adopts the combination form of the spiral drill bit and the spiral tap. In particular, there is a leading edge on the top of the auger bit, which has a centering effect when drilling, and the tail handle has a square structure, which can quickly load and unload the existing clamps of the quick clamping company. Tapping threads can be realized without tool change after drilling, and the scattered processes are reasonably concentrated, the number of processes is shortened, the process is simplified, the time for clamping and tool change is saved, the number of special machine tools and special fixtures is reduced, and the time is shortened. The production l...

Abstract

The invention discloses a combined tap and drill, belongs to the technical field of machining tool design and manufacture and provides a drilling and tapping integrated combined tap and drill which can ensure internal thread machining quality. The combined tap and drill comprises a tap and drill body, a guide drill hole cutting edge is arranged at the tip end of the tap and drill body, and a bottom hole before tapping is drilled in the tapping process by the tap and drill body under cooperation of the guide drill hole cutting edge.

Description

technical field [0001] The invention relates to a composite screw tap, which belongs to the technical field of mechanical processing tool design and manufacture. Background technique [0002] The traditional processing method of internal thread is to process the bottom hole of the thread with a drill bit suitable for the small diameter of the thread, and then use a tap to tap the thread. Its disadvantages are: more machine tools and processes are required, the processes are scattered, and the number of drill bits and taps is changed frequently. Not only is the productivity low, but also the coaxiality of the drill bits and taps after tool change is difficult to guarantee, which affects product quality and causes production problems. A lot of inconvenience. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a composite tap with integrated drilling and tapping that can guarantee the processing quality of internal thr...
