Background

At present, the precision grade of a mechanical two-micro feeding workbench with small feeding amount (suitable for 200mm) which is commonly used in China can be +/-0.02 mm. However, when the conventional numerical control system is used for processing and manufacturing an optical component, the working requirement of small-angle offset processing required by the optical component in micro-adjustment is shown to be difficult to provide. The fine adjustment small angle is less than +/-0.64 degrees, and if the indication light spot is accurately fine-adjusted to the target center, the mechanical two-step micro feeding of the worktable is difficult to realize, and continuous and uninterrupted fine adjustment is impossible.

The application range of the traditional mechanical double micro-feeding worktable is wide. The general structure of mechanical two-micro-feeding working table for machining, manufacturing and numerical control machine tool is that two-micro-feeding system (dynamic system) is fixed on the machine base (static system), and the two micro-directions of said system are mutually perpendicular to each other by 90 deg. and the self-collimation method using helium-neon laser as indication light, which is extensively used in general optical machining, has a deflection angle of about 9 deg.. If the angle can not be adjusted slightly, the error of the workpiece formed on the glass laser tube of the workpiece can be directly reflected.

Disclosure of Invention

In order to solve the above technical problems, an object of the present invention is to provide a precise bidirectional fine-tuning system with simple structure and high fine-tuning precision, which can continuously adjust the tiny angle of the processed component, and is more convenient for adjusting the tiny angle change by the auto-collimation method of the optical component.

In order to achieve the above object, the present invention provides a bidirectional fine adjustment system for a floating fine adjustment platform, which includes a bidirectional hinge structure of the floating fine adjustment platform and a hinge extension shaft. The hinge of the fine adjustment device rotates the page, the angle deflection arm of force, all install between two little feeding work benches of machinery and frame according to its corresponding position separately, after installing the two-way fine adjustment system, make two little feeding work benches of machinery and frame between, in a floating connection state, make two little feeding work benches of machinery have X, Y degrees of freedom of two direction angle fine adjustments.

Preferably, on the basis of the scheme, the bidirectional hinge structure is connected between the two micro-feeding working tables and the machine base, the longitudinal shaft of the bidirectional hinge is sleeved with the hinge rotating sheet and is arranged on the machine base, and the other rotating sheet of the hinge is arranged on the side face of the floating fine-tuning platform. The two-dimensional micro-feeding worktable can rotate the machine base in a two-dimensional angle micro-scale, including an X axial direction and a Y axial direction, and plays a role of a bidirectional rotation fulcrum.

In addition to the above-mentioned solution, preferably, the hinge extension shaft is a long shaft that is separated from the two-way hinge and is coaxial with the horizontal shaft of the two-way hinge. The hinge extension axis is in contact with the lower surface of the floating fine adjustment platform and is fixed on the machine base. Because the lower surface of the floating fine tuning platform is only in line contact with one side of the lower surface of the floating fine tuning platform, the lower surface of the platform far away from the other side of the hinge extension shaft is provided with a spherical fulcrum to lift and heave, and the fine tuning platform can be subjected to fine adjustment of the pitch angle.

Preferably, on the basis of the above scheme, the hinge extension shaft and the spherical fulcrum far away from the extension shaft form a floating bearing surface. A spherical micro-adjustment point is arranged on the side surface of the floating fine adjustment platform far away from the longitudinal axis of the double hinges, so that the floating fine adjustment platform can be subjected to micro-adjustment of left and right deflection angles.
