Abstract
The utility model relates to an eccentric clamp, in particular to a crankshaft eccentric clamp applicable to crankshaft machining industries. The crankshaft eccentric clamp comprises a base, a cover plate, pressing plates, a limit block and a fastening bolt. The base and the cover plate are coaxially fixed. A mounting cavity is formed in the base. A mounting groove is formed in the cover plate. The pressing plates are mounted in the mounting cavity and the mounting groove. The pressing plates include an upper pressing plate and a lower pressing plate. A fixing groove is formed between the upper pressing plate and the lower pressing plate. The fixing groove and the base are not coaxial. The limit block is fixed to the cover plate. The fastening bolt is rotationally mounted on the lower pressing plate and the cover plate and matched with the upper pressing plate. The crankshaft eccentric clamp is reasonable in design, simple and fast to assemble, and low in production and maintenance cost.
