Abstract
The invention relates to a crankshaft milling key seat clamp which comprises a bottom plate. A left V-shaped block, a locating block, a right V-shaped block and a centre rod are sequentially arranged on the upper end face of the bottom plate. The left V-shaped block and the right V-shaped block are arranged in parallel and located on the same symmetrical plane. The locating block and the right V-shaped block are arranged in parallel and arranged at one side of the symmetrical plane of the right V-shaped block. The centre rod is perpendicular to the right V-shaped block, and the axis of the centre rod is arranged on the symmetrical plane of the right V-shaped block. The centre rod is in threaded connection with the bottom plate. Pressing plates capable of moving vertically are arranged above the left V-shaped block and the right V-shaped block respectively. Supporting rods and bolts are arranged at one ends of the pressing plates. The supporting rods are arranged at the outer sides of the bolts. Nuts are arranged on the portions, above the pressing plates, of the bolts. The clamp is high in location precision, convenient to disassemble and simple in structure, and improves the machining precision and the machining efficiency.
