Problems solved by technology

However, when the end of the cutting blade 3 is subjected to the cutting force F1, the intersection line between the tool holder 2 and the end of the rotary cutter body 1 is the central axis O of the force, and the supporting force of the entire tool groove 11 on the tool holder 2 is concentrated. On the stressed central axis O, this structure makes the rotating cutter body 1 prone to deformation or collapse at the stressed central axis O; the torque generated by the cutting force F1 relative to the stressed central axis O can only be generated by the tool holder fastener The torque generated by the fastening force F2 of 4 is balanced, and the stability of the connection between the rotating tool body 1 and the tool holder 2 is completely guaranteed by the tool holder fastener 4. The greater the cutting force F1, the faster the tightening force generated by the tool holder fastener 4. The larger F2 is, the greater the force O of the rotating cutter body 1 is likely to be deformed or broken, which will cause loosening or displacement of the tool holder 2 and cutting blade 3, thereby greatly reducing the machining accuracy of the cutting tool. The fastener 4 may also be deformed or even broken due to excessive force, and the broken tool holder fastener 4 will fly out, which greatly challenges the safety

Abstract

The invention discloses a rotary cutting tool capable of axially and accurately locating. The rotary cutting tool comprises a rotary cutter body, a cutter holder, a cutting blade, a cutter holder fastening part and a cutting blade fastening part, wherein a cutter slot defined by a bottom locating surface, a first side locating surface and a second side locating surface is formed in the rotary cutter body, the cutting blade is fixed on the cutter holder by the cutting blade fastening part, the first side locating surface is a surface at which the cutter slot is opposite to an end cutting edge of the cutting blade, the cutter holder is radically inserted in the cutter slot along the rotary cutter body, the first side locating surface and the bottom locating surface form interference clamping locating to the cutter holder, and the cutter holder and the rotary cutter body are fixedly connected with each other by the cutter holder fastening part. The rotary cutting tool capable of axially and accurately locating has the advantages of high axial anti-shock capability, high locating precision, good safety and long service life.

Description

technical field [0001] The invention relates to a metal cutting tool, in particular to a rotary cutting tool with accurate axial positioning. Background technique [0002] Currently, people generally use figure 1 with figure 2 The rotary cutting tool shown includes a rotary cutter body 1, a tool holder 2, a cutting blade 3, a tool holder fastener 4 and a blade fastener 5, and the rotary cutter body 1 is provided with at least one set of tool grooves 11 , the cutting blade 3 is fixed on the tool holder 2 by the blade fastener 5 and placed in the tool groove 11 together with the tool holder 2. In this structure, the tool holder 2 is directly fixed by the tool holder fastener 4, and the tool holder 2 can be stably fixed in the knife groove 11. However, when the end of the cutting blade 3 is subjected to the cutting force F1, the intersection line between the tool holder 2 and the end of the rotary cutter body 1 is the central axis O of the force, and the supporting force of...
