A large-face milling fixture for disk parts

Abstract

The invention relates to a large face milling clamp for disc type parts. The large face milling clamp mainly comprises a base and a containing groove. A locating pin is installed on the containing groove. Driving plates are hinged to and installed on the periphery of the base. Clamping blocks are arranged at the ends, close to the containing groove, of the driving plates. Protruding arc faces are arranged at the ends, close to the front-back center of the base, of the driving plates. Arc sliding channels matched with the arc extending directions of the arc faces are formed in the arc faces. Motors are installed on the left side and the right side of the base and are connected with main driving bevel gears. Joint bevel gears are meshed with the upper portions and the lower portions of the main driving bevel gears. The joint bevel gears are coaxially connected with joint connecting plates. Spherical bodies installed in the arc sliding channels in a sliding manner are arranged at the ends, away from the joint bevel gears, of the joint connecting plates. According to the large face milling clamp for the disc type parts, on the basis that the disc type parts are located, the four driving plates can be controlled at a time to clamp the disc type parts through transmission of an axle, clamping is firm, and the milling quality of the parts can be indirectly improved.

Description

technical field [0001] The invention relates to the field of mechanical processing fixtures, in particular to a large surface milling fixture for disk parts. Background technique [0002] Generally speaking, the surface of disk parts often requires high machining accuracy, so the surface of conventional disk parts must be milled after casting. However, under normal circumstances, it is difficult to fix and clamp the disk parts with the fixtures on the conventional milling machine, and then it is difficult to perform subsequent milling. Contents of the invention [0003] Aiming at the defects of the above-mentioned technologies, the present invention proposes a large surface milling fixture for disc parts that can be conveniently milled. [0004] A large surface milling fixture for disk parts mainly includes a base and a placement groove at the center of the base, and a positioning pin is installed on the placement groove. When in use, the disk parts can be placed in the ...
