Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a double-edged adjustable boring tool. Background Technology

[0002] A boring bar is a type of boring tool, generally with a round shank, although square shanks are sometimes used for larger workpieces. It is most commonly used for internal hole machining, reaming, and contouring. It is a tool with one or two cutting parts, specifically designed for roughing, semi-finishing, or finishing existing holes. It can be used on boring machines, lathes, or milling machines. When using it, appropriate modules can be selected according to the requirements of the workpiece to assemble various boring bars, thereby simplifying the design and manufacturing of the tool.

[0003] The applicant discovered through a search that a Chinese patent discloses "An Adjustable Double-Edge Boring Tool," with publication (announcement) number "CN207695644U." This patent mainly realizes the detachability of the boring tool, making it easy to add or remove cutting edges and expanding the application range of the boring tool. However, the device uses a structure of fixed plates and locking blocks. Although it can realize the replacement and disassembly of cutting edges, it is difficult to precisely adjust the distance between the cutting edges. During the processing, it may be difficult to achieve fine adjustment and cannot meet the needs of fine machining. It focuses on the replacement and disassembly of cutting edges and lacks the function of flexibly adjusting the distance between cutting edges. This may limit the adaptability of the tool under different workpieces and different processing requirements. Therefore, we propose a double-edge adjustable boring tool. Utility Model Content
