[0026] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0027] This utility model provides a high-efficiency external milling cutter holder for crankshaft diameter machining, comprising:

[0028] The tool holder has multiple mounting slots on its surface for mounting the blade. Each mounting slot includes a bottom wall and multiple side walls. The bottom wall has mounting holes, and the bottom wall or slot wall has positioning protrusions that engage and fix with the blade.

[0029] Specifically, the tool holder in this tool holder needs to install multiple blades. The blades are positioned and fixed by the mounting slot of the tool holder, the position of the blades is limited by the positioning protrusion, and the blades are fixed by the mounting holes. This ensures the installation strength of the blades.

[0030] Optionally, the mounting groove includes a first sidewall and a second sidewall, the first sidewall and the second sidewall being in contact with the outer surface of the blade.

[0031] Optionally, a first rounded corner guide groove is provided at the connection between the first sidewall and the bottom wall and at the connection between the second sidewall and the bottom wall.

[0032] Optionally, the connection between the first sidewall and the second sidewall is provided in the second rounded corner guide groove.

[0033] Specifically, the mounting groove is provided with a first sidewall and a second sidewall in the circumferential direction. When the blade is installed in the mounting groove, the outer circumferential surface of the blade is fitted and fixed with the first sidewall and the second sidewall, which ensures that the blade is installed in the correct position. In addition, rounded guide grooves are provided at the corners connecting the sidewalls and at the corners connecting the sidewall and the bottom wall, so that the outer circumferential surface of the blade will not be completely fitted with the inner wall of the mounting groove, which facilitates the removal of the blade.

[0034] Optionally, at least two positioning protrusions are provided on the bottom wall, and the positioning protrusions are spaced apart on the outer periphery of the mounting hole.

[0035] Optionally, the longitudinal section of the positioning protrusion has a trapezoidal structure.

[0036] Optionally, the bottom of the blade is provided with a positioning groove that mates with the positioning protrusion, and the top wall of the positioning groove has an arc-shaped structure.

[0037] Optionally, the connection between the side and top of the positioning protrusion is a rounded corner structure.

[0038] Specifically, multiple positioning protrusions are set on the bottom wall, and the positioning protrusions are evenly distributed around the outer perimeter of the mounting hole. When the blade is installed on the bottom wall, the positioning groove of the blade is aligned with the positioning protrusion, which can ensure the accurate installation position of the blade. Since the positioning protrusion is conical, this also reduces the difficulty of blade installation. The top wall of the positioning groove is set as an arc structure, and the top of the positioning protrusion is set as a rounded corner structure, which can reduce the wear of the positioning protrusion after long-term installation.

[0039] Optionally, the top of the blade is provided with a countersunk hole, and the blade is connected to the mounting hole by a bolt, with the head of the bolt set inside the countersunk hole.

[0040] Optionally, one mounting hole is provided.

[0041] Specifically, a mounting hole is provided on the cutting tool to reduce damage to the overall strength of the cutting tool. A countersunk hole is provided at the top of the cutting tool so that when the bolt is installed on the cutting tool holder, the bolt can be completely hidden inside the cutting tool, preventing the cutting tool from accidentally hitting the bolt when machining the crankshaft.
