Lifting rotary adjusting mechanism for milling head of edge milling machine

Abstract

The invention relates to a lifting rotary adjusting mechanism for the milling head of an edge milling machine. The lifting rotary adjusting mechanism comprises a milling power head, a circular arc rotary part and a lifting part, wherein an arc-shaped guide rail is arranged on the front side of an arc-shaped guide rail seat; and the milling power head is matched with the arc-shaped guide rail through an arc-shaped guide groove. Compared with the prior art, the lifting rotary adjusting mechanism adopting the structure that a single shaft is taken as a rotating center has the advantages that the contact surface between the guide rail and the guide groove is larger, the stability is enhanced, milling cutter heads with larger specifications can be hung, and better machining precision can be guaranteed; and the overturning angle is large and can be 85 degrees, so that the angle positioning is more accurate. During the overturning process, a milling cutter head is kept in the rotation center all the time, that is, approximately the milling cutter head is kept on the edge of a sheet metal all the time, so that positioning can be fulfilled efficiently.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a milling head lifting and rotating adjustment mechanism for edge milling machines. Background technique [0002] In the existing edge milling machine, for the adjustment of the angle of the milling head, the mechanism disclosed in the Chinese patent "CN200910033956.0 --- Angle adjustment mechanism of the milling head of the edge milling machine" applied by the applicant is generally used. The rotating shaft is connected with the arc guide rail seat, and the milling head is installed on the mounting seat. Due to the direct rotation around the rotary axis and the limited distance for lifting adjustment, the angle range that the milling head can adjust in actual use is not large, and it can only meet the requirements of 0° (vertical end face of the plate) to 45° (bevel of the upper plate surface) Processing requirements, when it is necessary to mill a groove with a l...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the above-mentioned shortcomings that the rotating structure of the milling head of the existing edge milling machine cannot meet the needs of milling grooves with larger angles, the applicant provides a lifting and rotating adjustment mechanism for the milling head of the edge milling machine, which can make the angle range of the milling groove reach 0° ~85°
