Abstract

The invention relates to a flattening high-precision double-shaft rotary table for part manufacturing. The rotary table is lifted to a working platform of a milling machine, the position of the rotary table is fixed through a limiting block, a workpiece is clamped to the working platform of the rotary table, a main shaft and a pitch shaft handle are rotated to enable the workpiece to be located at the needed angle, a hydraulic locking device is started, and then the finish machining process can be started. The flattening high-precision double-shaft rotary table is compact in structure, convenient to operate, high in practicability and capable of rapidly and stably keeping the part at the specific angle and specific direction, and convenience is brought to the development of the follow-up finish machining procedure.

Description

technical field [0001] The invention relates to a flat high-precision double-axis turntable for parts processing, belongs to the field of precision processing, and relates to a horizontal milling machine, which can be used for precision processing of workpieces. technical background [0002] The research and development of testing and motion simulation turntables has been carried out in China since the 1960s, and the special technology has made great progress in the 1980s. In recent years, there have also been breakthroughs in the key technologies of active exploration and practice of large and complex turntables. At present, the main technical indicators of turntable equipment have approached or reached the advanced level abroad, and the products have occupied the main share of the domestic market. [0003] In the development and production of inertial navigation testing and precision motion simulation equipment, the 303rd Institute of AVIC has a history of more than 50 yea...
