Description

Technical Field

[0001] This utility model relates to the field of metal part positioning drilling technology, and specifically to a metal part positioning drilling device. Background Technology

[0002] Positioning drilling of metal parts is a machining process that uses specific techniques to ensure that the drill bit is accurately positioned on the surface of the metal workpiece and completes the drilling. Its core objective is to eliminate drilling offset, improve hole position accuracy, and increase machining efficiency.

[0003] In the field of metal parts processing, drilling is one of the common processing steps. Currently, most common metal parts drilling equipment on the market uses mechanical drill bits for drilling operations. Although this can meet basic drilling needs, in actual use, due to the different production requirements of metal parts, the drilling angle of some metal parts is different. However, mechanical drill bits are mostly installed in a fixed position, making it difficult to adjust the drilling angle according to drilling needs. In most cases, it is necessary to manually adjust the metal parts to adapt the angle, but there are potential safety hazards in the manual adjustment process. Utility Model Content
