Background

The full-numerical control cam grinding machine is special equipment for specially processing cam profiles. The equipment is a three-axis machine tool, namely an X axis, a Y axis and a C axis. The machining process is that the positioning fixture is assembled on a machined product, and the Y axis is the control axial position. The traditional machining process is to assemble the fixture on a product, locate the fixture by a locating pin or a locating key slot, drive the fixture and the product assembly to rotate by the rotation of the C shaft and the cooperation of a deflector rod, and grind and machine the molded surface and the phase angle of the product by the follow-up grinding of the X shaft. Thus, the method is suitable for a single-variety production mode and is not suitable for a small-batch multi-variety production mode. The existing cam positioning clamp is a special clamp, and the special clamp has the advantages of high reliability, stable positioning and relatively convenient clamping. But only one product can be clamped, and the universality is not realized. The special fixture is needed to be customized again due to different product specifications and different positioning references, and each special positioning fixture is long in manufacturing period and high in cost, and sample trial manufacture is abandoned after the special positioning fixture is manufactured, so that the cost is high and the cost is high.
