Double-rotary disc five-shaft rotary table structure of torque motor

Abstract

The invention discloses a double-rotary disc five-shaft rotary table structure of a torque motor. The double-rotary disc five-shaft rotary table structure comprises an inclined swinging shaft series assembly and a rotating shaft series assembly, wherein the inclined swinging shaft series assembly comprises an inclined shaft mechanism, a tailstock mechanism and a C-shaft machine body which are coaxially connected; the inclined shaft mechanism and the tailstock mechanism are arranged at the two ends of the C-shaft machine body; the rotating shaft series assembly is arranged on the C-shaft machine body; center lines of the rotating shaft series assembly and the inclined swinging shaft series assembly are orthogonal; the rotating shaft series assembly comprises an upper rotary disc and a lowerrotary disc; and the upper rotary disc and the lower rotary disc are coaxially relatively arranged at the two ends of the rotating shaft series assembly. According to the double-rotary disc five-shaft rotary table structure, processing efficiency is improved through design of the double rotary discs, and sealing performance is improved through design of a strengthened sealing structure.

Description

technical field [0001] The invention relates to the field of turntables, in particular to a five-axis turntable structure with torque motors and double rotary discs. Background technique [0002] The existing five-axis turntable is usually equipped with only one rotary table for clamping the workpiece for processing. This structure has certain limitations. Firstly, the allowed clamping method is fixed with a single rotary table. Secondly, the efficiency is low. After the parts are completed, they must be disassembled and assembled again to continue processing; the two turntables of a small number of double-disk five-axis turntables in the market need to be connected to two power mechanisms, and they are arranged side by side, which has certain disadvantages. First of all, this structure leads to five The overall size of the axis turntable is relatively large, so it will increase the overall size of the five-axis machine tool, the stroke of the linear axis, etc. Secondly, the...
