Description

Technical Field

[0001] This utility model belongs to the field of cutting tool technology, specifically relating to a boring tool for an assembly boring machine. Background Technology

[0002] A boring bar is a type of tool used for machining holes. It typically has a round shank, although a square shank is sometimes used for larger workpieces. It is commonly found on vertical lathes and is most frequently used for machining internal holes, reaming, and contouring. To accommodate various hole diameters and depths and to reduce the variety of boring bar specifications, boring bars and tool heads have been designed as modular components. When using them, appropriate modules can be selected based on the workpiece requirements to assemble various boring bars, thus simplifying tool design and manufacturing.

[0003] A search revealed that publication number CN100531977C relates to a boring tool, the key technical points of which are: it includes a tool body, on which a tool holder is mounted, the tool holder being radially adjustable, and a rotatable adjusting member disposed on the tool body for laterally moving the tool holder; and an axial drive mechanism for setting the boring diameter, the axial drive mechanism converting the rotation of the adjusting member into the translation of the tool holder, thereby precisely adjusting the boring diameter; furthermore, the adjusting member has a scale, the distance between two lines on the scale corresponding to a displacement of one micrometer;

[0004] The above process allows the adjustment component to rotate via axial drive, which is simple in structure and saves time. However, there are still some drawbacks in this process. It requires high precision between the tool body and the tool holder, and the manufacturing process is difficult. It is also difficult to control the accuracy of the tool head position. In view of this, we propose a new type of assembled boring tool for boring machines to solve the above problems. Utility Model Content
