Abstract

This invention relates to the field of machining technology for medium and large castings, and particularly to a tapping device for products with complex spaces and limited machine tool processing space. The tapping device includes a first positioning device, a second positioning device, a locking device, and a tap. The first positioning device and the second positioning device are movably engaged. The locking device is used to lock the second positioning device and the first positioning device. The tap is fixedly connected to the second positioning device. This invention solves the problem of spatial interference correction drilling and tapping in the prior art, and provides a spatial interference correction drilling and tapping device. This spatial interference correction drilling and tapping device includes an arc-shaped positioning and fixing device and a movable tooth-shaped positioning device, achieving efficient and reliable drilling and tapping of interference holes with different angles and heights.
