Description

Reamer with adjustable blade locking mechanism Technical Field The utility model relates to a reamer, in particular to a reamer with an adjustable blade locking mechanism, and belongs to the technical field of reamer. Background The reamer is a tool for further processing a processed hole so as to enlarge the aperture and improve the processing precision and the surface quality of the hole, the tool body is driven to rotate by a driving device of a machine tool, the tool is fed along the axis direction of the hole, the cutting edge of the blade is contacted with the inner wall of the processed hole, and the material on the hole wall is gradually cut off under the combined action of rotation and feeding movement, so that the purpose of enlarging the aperture is realized. In the prior art, as the reaming cutter with the guide support is disclosed by the publication No. CN219484311U, the cutter bar structure is optimized, so that the cutter bar is a two-section cutter bar, the diameter of the rear section cutter bar is larger than that of the front section cutter bar, and the rear section cutter bar and the front section cutter bar are connected by a truncated cone with transitional function. However, in the related art, it has been found that the reamer with guide support of the above design has a problem that the stability of the machining can be improved by the cooperation of the cutter bar and other components in the prior art, but in the specific use process, when the cutter blade is worn during the machining process or the cutter blade with different sizes is replaced, the whole cutter needs to be replaced, resulting in low efficiency, and in view of the above, the reamer with the adjustable blade locking mechanism is provided to overcome the defects. Disclosure of utility model The utility model provides a reamer with an adjustable blade locking mechanism for solving the technical problem that the blade cannot be replaced.
