Problems solved by technology

[0002] At present, when using a milling cutter to mill a hole, it is basically necessary to use a large-scale CNC machine tool to complete it. Obviously, for large workpieces, it is not conducive to transporting it to the CNC machine tool for processing
In the prior art, holes of different sizes and diameters are milled with the same milling cutter. The realization form is that the milling cutter rotates on its own, and at the same time revolves around a certain power structure, and the radius of the revolution is adjustable, so that different diameters can be obtained. Milling holes, but in the existing structure, the structure is complicated when adjusting the revolution radius, which is easy to cause damage between the mating parts

Abstract

The invention discloses a milling device used for processing holes, which is characterized by being convenient to adjust the revolution radius of a milling cutter. The milling device comprises a milling seat arranged on a guide rail, a milling shaft used for assembling the milling cutter and a motor for driving the milling shaft to rotate around the axis line thereof; the milling seat is providedwith a dynamical structure which can applies action force to the milling shaft; the dynamical structure drives the axis line of the milling shaft to revolve around the axis line of the dynamical structure; a middle transmission shaft is connected between the milling shaft and the motor in a transmission manner and is sheathed on the dynamical structure in an eccentric manner; and a dynamical device for driving the milling shaft to rotate around the axis line of the middle transmission shaft is connected on the milling shaft in a transmission manner. Due to the arrangement of the middle transmission shaft, the milling device can realize rotation of the milling shaft around the axis line of the middle transmission shaft, thus being convenient to adjust the vertical distance between the axisline of the milling shaft and the axis line of the dynamical structure, and especially being suitable for being promoted and used in the processing of various holes with different diameters.

Description

technical field [0001] The invention relates to a milling device, in particular to a milling device for processing holes. Background technique [0002] At present, when using a milling cutter to mill a hole, it is basically necessary to use a large-scale CNC machine tool to complete it. Obviously, for large-scale workpieces, it is not conducive to transporting it to the CNC machine tool for processing. In the prior art, holes of different sizes and diameters are milled with the same milling cutter. The realization form is that the milling cutter rotates on its own, and at the same time revolves around a certain power structure, and the radius of the revolution is adjustable, so that different diameters can be obtained. Milling holes, but in the existing structure, the structure is complicated when adjusting the revolution radius, which is easy to cause damage between the mutual matching parts. Contents of the invention [0003] The technical problem to be solved by the pr...
