Description

Positioning tungsten steel milling cutter disc assembly Technical Field The invention relates to the field of tungsten steel milling cutters, in particular to a positioning tungsten steel milling cutter assembly. Background The tungsten steel milling cutter disc is a high-performance cutting tool made of tungsten steel (hard alloy), has extremely high hardness and wear resistance, is inferior to diamond, and is suitable for processing high-hardness materials such as stainless steel, alloy steel, quenched steel and the like at high speed. The cutting tool has various structures, including standard tools (diameter is 1-20 mm) and nonstandard tools, and can be divided into 45 degrees, 90 degrees and other types according to the main deflection angle, and the cutting tool is respectively used for scenes with different cutting force requirements. Through inspection, publication number CN117086376A discloses a positioning tungsten steel milling cutter disc assembly, wherein one of two side ends of a chip groove is provided with a blade mounting groove, a cutting blade is arranged in the blade mounting groove, and the cutting blade is fixedly arranged on a milling cutter disc through a fastening device. The back of the cutting blade is fixedly provided with a compression block, two side surfaces of the compression block are provided with inclined compression grooves, the fastening device comprises a compression plate and a locking bolt, an insertion plate which is matched with the compression grooves and is in sliding connection with the compression grooves is fixedly connected to the compression plate, the locking bolt is rotationally connected to the compression plate, and the locking bolt is in threaded connection with the milling cutter disc, so that the situation that the chip grooves are not too small while the blade is directly grooved is avoided, and the rigidity of the blade is not damaged and unsmooth chip removal is not caused in the process of installing the blade; In the above-mentioned reference, there is a problem in that, in particular, the fastening device is manually assembled by means of the pressing plate, the inserting plate and the locking bolt, the orientation bar needs to be precisely aligned with the orientation groove, the orientation bar is easily loosened due to tiny dislocation in a high-speed rotation environment, the installation time and the error rate are increased, the pressing block is fixed on the blade, if the pressing block is damaged, the whole blade needs to be replaced, and the maintenance cost is high.
