Parallel multi-turntable numerical control clamp

Abstract

The invention discloses a parallel multi-turntable numerical control clamp. The parallel multi-turntable numerical control clamp comprises a clamp body and a rotating mechanism, wherein the clamp body adopts a U-shaped structure; the rotating mechanism which controls turntables to rotate is mounted on one side of the clamp body of the U-shaped structure; a second rotating shaft and a bearing which support the turntables to rotate are mounted on the other side of the clamp body of the U-shaped structure; the rotating structure comprises a servo motor; an output shaft of the servo motor is connected with a worm; the worm is erected on one side of the clamp body through a pair of bearing seats; the other end of the worm is fixed with a pulse encoder; a plurality of first rotating shafts are mounted on the side wall of the side, provided with the worm, of the clamp body; worm wheels matched with the worm are mounted on the first rotating shafts; the other ends of the first rotating shafts are connected with second rotating shafts; the turntables are respectively mounted on each second rotating shaft in parallel. The invention discloses the numerical control clamp that a plurality of parallel turntables are controlled to rotate together through a precise worm wheel-worm transmission mechanism; a plurality of workpieces can be clamped; a plurality of working station surfaces can be machined; the machining efficiency of a numerical control machine tool is improved; the batch production capacity of the numerical control machine tool can be played.

Description

technical field [0001] The invention belongs to the field of fixture design of a numerical control machine tool, and in particular relates to a numerical control fixture with parallel multi-turntables. Background technique [0002] The field of modern mechanical numerical control machining is more and more oriented towards mass customization and batch-scale production. Considering that numerical control machining is characterized by a high degree of process concentration, it is required that the fixture has a certain flexible function and can adapt to multi-process and multi-station processing in a certain field. All kinds of shell workpieces required can be clamped on the CNC machine tool to complete the processing of multiple surfaces as much as possible. If the high-end four-axis and five-axis machining centers can be used to complete the multi-surface processing of the workpiece in one clamping, it is not suitable for In the mass production mode, the use of a cost-effect...
