Problems solved by technology

Since the end of the fastening screw tightens the peripheral surface of the transition sleeve, the result is: the milling cutter rotates at high speed during the working process, and is affected by the cutting resistance to generate a large torque, which directly causes the fastening screw to The fastening effect on the transition sleeve cannot be maintained. The slight consequence

Abstract

The invention relates to an assembly structure of a disc type milling cutter. The assembly structure comprises a connecting rod connected with a machine tool, wherein a cavity with open bottom is formed in the lower end of the connecting rod, a transitional joint sleeve is matched in the cavity, a radial hole is formed in the circumferential surface of the connecting rod, fastening screws for fastening the transitional joint sleeve in the cavity of the connecting rod are connected in the radial hole, a tightening screw is arranged at the top of the transitional joint sleeve, a Morse taper hole for mounting the milling cutter is formed inside the tightening screw, one end of the milling cutter is assembled in the Morse taper hole and then fixed by the tightening screw, a spherical mounting hole is formed in the circumferential surface of the transitional joint sleeve, the fastening screws penetrate through the radial hole in the connecting rod and are in threaded connection with the spherical mounting hole in the transitional joint sleeve, and end parts, located in the mounting hole, of the fastening screws are spherical surfaces. The transitional joint sleeve can be fastened reliably and prevented from being thrown out and hurting people.

Description

technical field [0001] The invention relates to an assembly structure of a disc milling cutter. Background technique [0002] Small boring machines are widely used in the field of mechanical processing. The existing small boring machines usually use a T-nut tightening milling tool holder. This type of milling tool holder can meet the basic processing needs, but this type of milling tool holder has structural defects. , that is, a waist-shaped groove is opened in the middle section, so that the length of the entire boring machine milling cutter device is longer. This structure reduces the milling strength and rigidity of the milling tool handle, and it is easy to generate vibration during milling and reduce the milling speed. [0003] The publication number is CN201783689U, which discloses a boring mill milling tool holder, which mainly includes a boring tool bar. The lower end of the boring tool bar is provided with a cavity with a bottom opening. connection, the top of the...
