Six-rod whole hinge double-row drive type double pendulum angle milling head

Abstract

The invention relates to a single bolt driving dual oscillating milling head. The first controllable generator fixes with the first cylinder gear through the first coupler, the second cylinder gear fixes with the milling head sleeve top cover, top cover of the milling head sleeve and the first pair of side cover connects with the milling head sleeve respectively, the second and the third controllable generator installing on the first and second bracket respectively, the first and the second bracket fixed inside the milling head sleeve, six pairs of linking bracket and four pairs of linkages symmetrically set at both sides of the main shaft of the milling head. The first and second drive shaft fix with the second and third controllable generator, six pairs of linking bracket and four pairs of linkages form into eight rotating assistance, the second, the third, the fifth and the sixth pairs of linking bracket connect to the milling head sleeve through rotating assistance, with the third pair and the sixth pair of linking bracket and the milling head main shaft. 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-hinged double-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] The dual pendulum milling head is the core component of multi-axis control and five-axis linkage CNC machine tools. It mainly serves large and heavy-duty CNC and ordinary milling and boring machine tools. The host machine is equipped with this type of CNC milling head to control two-axis rotation to achieve five-axis linkage for complex processing. The three-dimensional surface expands the processing range and use functions of the host, greatly improves production efficiency and helps ensure processing accuracy. Because of its superiority, not only the proportion of users who order the host is increasing, but the number of users who have already used the ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a six-bar full-hinge double-row driven double-swing angle milling head, so that it can meet the working requirements of the double-swing milling head by adopting a new mechanism configuration of closed low-pair transmission, This configuration has the characteristics of high load, high rigidity, and large rotation angle. The rotation angle around the two axes can reach ±180° and greater than ±90° respectively, which meets or exceeds the international standard of similar products, and can solve the problem of the current double pendulum milling head due to high The auxiliary transmission has problems such as large volume, low rigidity, and low load-carrying capacity
