Description

Technical Field

[0001] This utility model relates to a drilling device, and more particularly to a batch multi-angle drilling machine. Background Technology

[0002] In the existing technology, the hole design of many workpieces is very complex, requiring multiple drillings on different surfaces and at different angles to meet production requirements. For example, the high-voltage plug panel of automotive parts has multiple holes for connecting with other components, so drilling equipment is needed to drill holes in multiple positions. Since the structure of the high-voltage plug panel has multiple surfaces with different angles, drilling needs to be performed in accordance with the angle of the surfaces.

[0003] Since existing drilling machines do not have the capability to operate multiple drill bits simultaneously or drill at multiple angles, in most cases, it is necessary to drill holes in the workpiece one by one, while simultaneously adjusting the position of the workpiece on the fixture. This adjustment is even more frequent when there are holes with different angles on the workpiece.

[0004] Existing advanced drilling machines can automatically drill holes at various positions through CNC programming and can also complete drilling at different angles using robotic arms. However, when there are many holes on the workpiece, the processing time is long, and the drill bit is prone to overheating and damage after repeated use. Therefore, existing drilling machine technology can be further optimized. Utility Model Content
