Abstract

The invention discloses a rotary expansion type workbench mechanism. The rotary expansion type workbench mechanism comprises a workbench. Clamping mechanisms used for clamping disc parts are arranged on the workbench and comprise the central clamping mechanism and the edge clamping mechanism which is used for clamping the edges of the disc parts. The central clamping mechanism comprises a fastening sleeve which is fixedly mounted on the workbench. An expansion sleeve is arranged in the fastening sleeve in a sleeved mode. A central inner hole is formed in the expansion sleeve. The open end, located in the central inner hole, of the expansion sleeve is an expansion end, and the other end of the expansion sleeve is a connecting end. At least three expansion grooves are circularly and evenly distributed in the expansion end of the expansion sleeve. A conical matching structure is arranged between the outer circumferential wall of the expansion sleeve and the wall of the inner hole of the fastening sleeve. An expansion hydraulic cylinder which is used for being connected with the connecting end and tensioning the expansion sleeve is arranged below the workbench. A workbench rotary shaft and a rotary driving mechanism used for driving the workbench to rotate are also arranged below the workbench.

Description

Technical field [0001] The invention belongs to the technical field of numerically controlled machine tools, and particularly relates to a rotary expansion and tightening worktable mechanism for numerically controlled machine tools. Background technique [0002] Companies in the modular machine tool industry mainly provide special equipment for automobiles, motorcycles, internal combustion engines, agricultural machinery, construction machinery, chemical machinery, military industry, energy, light industry and home appliances, and gradually began to transform to numerical control and flexibility.
