Rotating component for transmitting electricity, gas, liquid and rotating power during rotating

Abstract

The invention provides a rotating component for transmitting electricity, gas, liquid and rotating power during rotating. The rotating component is characterized in that at least three layers of stacked upper conductive slip rings and lower conductive slip rings are sleeved on the upper part and the lower part of a rotating shaft body respectively; at least three layers of stacked upper carbon brushes and lower carbon brushes are arranged on the upper part and the lower part of a metal shell respectively; at least three layers of rotating pipelines are sleeved outside the part of the rotatingshaft body positioned between the stacked upper conductive slip rings and the stacked lower conductive slip rings; the metal shell is provided with at least three layers of annular joints; each layerof rotating pipelines correspond to each layer of annular joints one by one and are sealed by sealing components; an output pipe and an input pipe are introduced out of each layer of rotating pipelines and each layer of annular joints respectively; and a rotating shaft transmits power to a main shaft box through a gear transmission component. The rotating component has the advantages that the rotating shaft can rotate in any cycles and does not limit the swing of a swing shaft.

Description

technical field [0001] The invention relates to a rotary component in a numerically controlled machine tool with five-axis linkage processing capability. Background technique [0002] At present, the domestic machinery industry is "point processing" with ball cutters in processing curved surfaces. The United States and Europe have developed to "line processing" with milling cutters (such as the EU Flank Milling Optimization project) and "surface processing" with disc cutters, which can improve work efficiency. More than ten times; especially when processing rotating curved surfaces, the work efficiency of disc cutter "surface processing" is dozens of times higher than that of ball cutter "point processing". The processing of a rotating parabolic mask with a diameter of 5 meters (such as the fairing of a large launch vehicle) requires one or two days for the "surface processing" technology of the disk cutter, and more than one month for the "point processing" of the ball cutt...

Problems solved by technology

[0009] It is ideal to put the main motor into the ram, because there is enough space in the ram so that the torque and power of the main motor are not limited by the volume of the motor, but the transmission with a universal joint will limit the A-axis (or B-axis) Swing angle (cannot exceed ±90 degrees); put the main motor directly into the milling head body, the torque and power of the main motor must be small enough (limited by the volume of the milling head body), it is difficult to meet the requirements of tens of thousands of NM and hundreds of milling heads for large machine tools. kilowatt power requirements
