Rotary table based on zero point positioning and application thereof

Abstract

The invention belongs to the field of machine tool machining and production, and particularly relates to a rotating table based on zero point positioning and application of the rotating table. According to the technical scheme, the rotary table comprises a sliding base, a rotary base, a working table plate, T-shaped guide rails, a rotary table bearing, a rotation control mechanism, a lifting control mechanism and a locking mechanism, the rotary base is rotationally connected with the sliding base through the rotary table bearing, the two T-shaped guide rails are symmetrically installed on the upper end face of the rotary base, and two T-shaped guide grooves are formed in the lower end face of the working table plate; the working table plate is mounted on the T-shaped guide rails through the T-shaped guide grooves; a plurality of zero-point positioning female discs are arranged on the upper end face of the rotary seat, a plurality of zero-point positioning male heads are arranged on the lower end face of the working table plate, and the zero-point positioning male heads correspond to the zero-point positioning female discs one by one in position; the rotation control mechanism, the lifting control mechanism and the locking mechanism are used for controlling rotation, lifting and locking of the workbench plate. The device is reliable and stable in positioning, large in locking torque, high in repeated positioning precision and capable of achieving rapid exchange of parts.

Description

technical field

[0001] The invention belongs to the field of machine tool processing and production, and particularly relates to a rotary worktable based on zero point positioning and its application. Background technique

[0002] In the process of automated production, it is necessary to reduce the number of clamping and installation positioning of workpieces to improve the machining accuracy and machining efficiency of parts. Aerospace parts are characterized by small batches and long processing times in one clamping. The application of the zero point positioning mechanism is increasing year by year, but most of the zero point positioning mechanisms are used on the fixture. The working table with it is attached with a zero-point positioning master plate, and an additional external pipeline is added. It is more troublesome for the rotatable worktable to connect the pipeline, and it is even more difficult for the exchangeable worktable. SUMMARY OF THE INVENTION
