Six-DOF (degree of freedom) attitude adjustment device

Abstract

The invention provides a six-DOF (degree of freedom) attitude adjustment device for a nozzle ladle. The six-DOF attitude adjustment device comprises a left-right moving mechanism, a rotating mechanism, a left vertical moving mechanism, a right vertical moving mechanism, a left front-back moving mechanism and a right front-back moving mechanism, wherein the left-right moving mechanism is connected with a rack; the rotating mechanism is connected with a left-right moving mechanism platform through two rotating shafts; the left vertical moving mechanism and the right vertical moving mechanism are arranged on two sides of the rotating mechanism respectively through screws and nuts; the left front-back moving mechanism is connected with the left vertical moving mechanism through a screw and a nut; the right front-back moving mechanism is connected with the right vertical moving mechanism through a screw and a nut; the nozzle ladle is in contact connection with the left front-back moving mechanism through two points and is connected with the right front-back moving mechanism through a spherical hinge. The six-DOF attitude adjustment device is simple in structure and convenient to adjust, the six-DOF positions and attitudes of the nozzle ladle relative to a cooling roller can be adjusted rapidly, so that the strip producing precision is higher, and the quality of amorphous ribbon products is improved greatly.

Description

technical field [0001] The invention relates to the production field of amorphous strips, in particular to a six-degree-of-freedom attitude adjustment device. Background technique [0002] Amorphous ribbon is a new type of alloy material that appeared in the late 1960s, and it is a functional material with a new microstructure. The preparation technology of amorphous strip is different from the traditional cold-rolled metal thin strip preparation technology. It usually adopts the rapid cooling technology, that is, the alloy solution in the molten state flows to the surface of the cooling roll through the nozzle, and the cooling roll is Rotating at a constant speed, when the alloy solution falls on the surface of the rapidly rotating cooling roll, the molten alloy will rotate with the cooling roll due to inertia and rapidly cool to form an amorphous strip. The quality of the amorphous strip product is related to the distance between the bottom surface of the nozzle and the c...

Problems solved by technology

[0005] However, there are three relative positions and rotational angles and attitudes between the nozzle package and the cooling roller, and a total of six displacements and angles need to be adjusted. However, most of the attitude adjustment mechanisms of the nozzle package in the existing patents have few degrees of freedom. When adjusting the position and attitude of the nozzle package, there will be a large difference between the nozzle package and the cooling roll displacement or attitude in a single direction, which cannot meet the requirements for producing amorphous strips, and it is easier to produce waste strips, and the production efficiency is low.
