Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for rotary drilling rigs, and in particular to an auxiliary clamp for rotary drilling rigs. Background Technology

[0002] With the development of my country's manufacturing industry, large slewing bearings are being used more and more widely, and the bearing sizes are becoming increasingly larger. For large slewing bearings and the flanges they mate with, 360-degree rotary machining centers can conveniently perform milling and drilling on the flange surfaces. However, in practical use, due to the increasing size of bearings, the rotary arms used for machining are also becoming longer. During drilling, the longer cantilever arms result in insufficient rigidity, leading to vibration. This vibration can cause tool ejection or breakage, damaging the tool or, in severe cases, the workpiece, resulting in significant economic waste, extended production time, and wasted manpower and resources. Therefore, ensuring the stability of the drill bit during drilling is crucial for the entire machining process. To ensure the stability of the rotating cantilever arm during drilling and minimize swaying and vibration, it is necessary to design a drilling machine auxiliary fixture. Utility Model Content
