Clamp transformation mechanism for large machine tool

Abstract

The invention discloses a clamp transformation mechanism for a large machine tool. The mechanism comprises a fixed main aluminum plate, a bridge plate abuts against the top face of the middle of the fixed main aluminum plate in a pressing mode, positioning columns are fixed to the front portions and the rear portions of the left side and the right side of the bottom face of the bridge plate correspondingly, the positioning columns are inserted into positioning inserting holes formed in the middle of the fixed main aluminum plate in a sleeved mode, the top face of the bridge plate is provided with at least two sets of clamping mechanisms, each set of clamping mechanism comprises multiple pressing fixed air cylinders, the upper portions of the pressing fixed air cylinders are fixed to the top face of the bridge plate, cylinder bodies of the pressing fixed air cylinders are inserted into vertical through holes in the bridge plate in a sleeved mode, and pressing arms are fixed to the endsof push rods of the pressing fixed air cylinders. The fixed main aluminum plate can be fixed to the large machine tool of a large machining center, the bridge plate is installed on the fixed main aluminum plate, the clamping mechanisms installed on the bridge plate can accurately position, clamp and fix small aluminum parts to be clamped, therefore, the large machining center can machine the aluminum parts to be clamped, the using ratio is improved, and idling is avoided.

Description

Technical field: [0001] The invention relates to the technical field of auto parts processing, in particular to a fixture conversion mechanism for a large machine tool. Background technique: [0002] Existing aluminum alloy parts for automobiles, such as automobile steering column brackets, need to be processed after casting, and because they are small parts, they cannot be clamped and fixed on large machine tools in large machining centers. For processing, it can only be processed in the machining center of the small machine tool, and the time used by the large machining center is not as much as that of the small machining center, which will generate idle time. At this time, the large machining center will generate waste. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a clamp conversion mechanism for large machine tools, which can fix the fixed main aluminum plate on the large machine tool of ...
