[0001] The present invention relates to the technical field of mechanical processing tooling, and in particular to a drilling, tapping and milling tooling. Background Art

[0002] In the process of mechanical processing, we often encounter some angled workpiece inclined holes that need to be processed. The processing of these inclined holes mainly involves drilling, tapping, milling and other processes, and the angles and positions of these workpiece inclined holes are irregular, so the processing of inclined holes becomes a processing difficulty.

[0003] To solve this problem, the following solutions are mainly adopted in China: First, for inclined holes with low precision requirements, simple pads are generally used to find the approximate angle and clamp the workpiece before processing, but this processing method is inefficient and not suitable for batch processing of inclined holes of workpieces; second, some simple tooling is used to process the inclined holes of the workpiece, but there are problems such as low processing accuracy and poor versatility of tooling; third, according to the requirements of workpiece processing accuracy and processing quantity, domestic or imported special equipment is used for processing, but this equipment is expensive and not suitable for the production and manufacturing of small and medium-sized enterprises.

[0004] To this end, it is urgent to develop a drilling, tapping and milling tooling to improve the processing efficiency and accuracy of the inclined holes of the workpiece, as well as to improve the versatility of the tooling itself, so as to meet the needs of small and medium-sized batch production and small and medium-sized enterprises.
