Detailed Description

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.

Examples are given.

See fig. 1-5.

The embodiment discloses an adjustable crankshaft machining clamp which comprises a base 1, a base plate 2 and a V-shaped clamping device 3; a V-clamp 3 is mounted on the base plate 2 for clamping and fixing the crankshaft 5. Base 1 level sets up, and base plate 2 and base 1 link together through connecting axle 6, and base plate 2 can rotate the setting around connecting axle 6, thereby base plate 2 is through rotating to be the level and sets up on base 1 or be the one side of setting at base 1 vertically.
