The invention relates to a precisely positioned rotary worktable mounted on a machine tool body. The precisely positioned rotary worktable comprises a worktable, a spindle, a positioning part, a sliding table part, a driving plate part, a worktable position detection part and a shell, wherein the spindle, the positioning part, the sliding table part and the driving plate part are mounted in the shell; the sliding table part is connected to the lower end of the spindle through the driving plate part, a rotating part of the positioning part is fixedly mounted on the spindle, and the positioningpart is mounted on the shell; the worktable is horizontally mounted at the upper end of the spindle; and the worktable position detection part is arranged on the shell through the side edge of the spindle. The rotary worktable is precisely positioned by adopting a rat fluted disc structure; a servo motor is fully replaced by a pneumatic mode by matching the sliding table part with the driving plate part for controlling the driving process, so that the failure rate is low, the equipment cost and the maintenance cost are lowered greatly, and the positioning precision and stability are improved.
Description
technical field [0001] The invention relates to a mechanical rotary device, in particular to a precise positioning rotary table. Background technique [0002] The processing of parts generally needs to go through multiple processes such as turning, milling, planing, grinding, etc. Different processes are processed by different machine tools, and the machine tools must be converted. The process of converting machine tools is not only cumbersome, but also increases the labor intensity of workers, and the conversion process is difficult. , It is also inevitable to bump and scratch the processed surface, which will affect the processing accuracy, especially for small workpieces with high precision requirements, and it is not easy to convert. Taking milling as an example, it is generally carried out by various types of milling machines, such as vertical milling machines, horizontal milling machines, and universal milling machines. Workpieces and parts that require high machining...
