Variable-diameter outer half-pipe curved surface multi-point positioning clamping numerical control milling clamp

Abstract

The utility model discloses a variable diameter outer half pipe curved surface multi -point positioning clamping numerical control milling clamp, its characterized in that, include: the small end positioning board and big end positioning board of inclination setting, the extension line of both is V -shaped after intersection, and the small end positioning board and big end positioning board are all polygonal board type structure, and the shape of polygonal structure is matched with the inner wall appearance of big end or small end of corresponding outer half pipe blank, and the plane of small end positioning board and big end positioning board is perpendicular to each other, and the small end support board and big end support board are connected with the connecting plate between, and the upper of connecting plate is provided with a triangle reinforcing support board in parallel, and the vertical reinforcing support board is fixedly connected with a support board adjusting column downward, and the lower section of support board adjusting column is connected on the connecting plate, and the upper of reinforcing support board is provided with reinforcing support nail at three vertexes, and its solved the problem of the fixture in prior art in the clamping process to the size difference of outer elbow's inclusions, can not guarantee the positioning accuracy.
