Crankshaft machining clamp

Abstract

The invention relates to the technical field of fixtures, in particular to a crankshaft processing fixture, which has a rectangular fixture body arranged opposite to the balance weight of the flying shear crankshaft. There are two fixed threaded holes located on both sides of the clamping through hole symmetrically in the width direction of the rectangular fixture body, and there are also provided in the thickness direction of the rectangular fixture body corresponding to the position of the four-jaw chuck. The corresponding fixing through hole and the correction through hole on a straight line with the major axis of the flying shear crankshaft. The fixture can control the quality and cycle of crankshaft processing and reduce the cost.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a crankshaft machining fixture. Background technique [0002] Crankshafts are used more and more widely. They are often used in steel rolling, papermaking and other production lines. Crankshafts are one of the important components to ensure the shear quality of products. In the past, all crankshafts were processed by outsourced special machine tools, with high cost and long cycle time. The difficulty of crankshaft machining is mainly reflected in two aspects: (1) The structure of the crankshaft is complex, and it is difficult to determine the center of rotation on the lathe; (2) When machining the crankshaft rotary motion, the inertial motion weight distribution is uneven, which affects the machining accuracy, and the crankshaft rotates quickly It is also easy to cause the crankshaft to fall off from the clamping position of the machine tool.
