Technical Field
[0001] The utility model relates to the technical field of machining equipment, and particularly relates to a combined structure of a diameter-adjustable boring tool and a boring tool fixture. Background Technique
[0002] A boring tool is a kind of hole machining tool. Generally, it has a round shank, and there are also square tool bars for larger workpieces, which are generally seen in vertical lathes. The most common applications are internal hole machining, reaming, profiling, etc. However, it is not only used for internal hole machining. The end face and outer circle can also be machined, but it is not used in this way by convention.
[0003] The existing boring tools generally have a fixed structure. During use, they can generally only bore holes of a specific size. If a larger hole needs to be bored continuously, different boring tools need to be replaced, which is relatively inconvenient to use.
