Abstract

The invention relates to a single bolt driving dual oscillating milling head. The No.1 controllable generator fixed with No.1 cylinder gear through No.1 coupler, No.2 cylinder gear fixed with the cover of the milling head cover, whose top cover and a pair of milling sleeve side cover fixed with the milling head sleeve, No.2 controllable generator installed on the bracket that fastened inside the milling head sleeve. Three pairs of linking brackets and two pairs of linkages set symmetrically at both sides of the electric main shaft of the milling head. The drive shaft fixes with the second controllable generator through the second coupler and fixed with the first pair of linking bracket. The first pair of linkage and the first pair of linking bracket or the second pair of linking bracket, the second pair of linkage and the second pair of linking bracket or the second pair of linkage and the third pair of linking bracket to form into rotating assistance respectively. The second and the third linking bracket connect to the milling head sleeve respectively, with the third linking bracket fixed with the main shaft of the milling head. It solves the issue of big size, low rigidity and poor bearing ability of the dual oscillating milling head.

Description

technical field

[0001] The invention relates to a milling head in the technical field of machine tools, in particular to a six-bar full-hinge single-row drive type double-swing angle milling head, which is suitable for heavy-duty multi-axis numerical control high-precision high-speed machine tools. Background technique

[0002] Double pendulum milling head is the core component of multi-axis control and five-axis linkage CNC machine tools. It mainly serves large and heavy CNC and ordinary milling and boring machine tools. The main engine is equipped with this kind of CNC milling head to control two-axis rotation to realize five-axis linkage to process complex The three-dimensional curved surface expands the processing range and use functions of the main machine, greatly improves the production efficiency and helps to ensure the processing accuracy. Because of its superiority, not only is the proportion of configuration when users order mainframes increased, but also the numb...
