Research on the Constant Removal Rate of Coordinate Finishing Crankshaft Crankpin with Abrasive Tap

Abstract

Coordinate polishing technology with abrasive tap is targeted for crankshaft, camshaft, eccentric shaft and other complex surface polishing. In the process of coordinate polishing crankshaft crankpin with abrasive tap, the constant removal rate is to ensure accuracy rate of removal, which is very important factor. This article is to mainly analyze constant rate of removal. First, analyzing the movement model of a single abrasive and on the exact model and the constant speed along under the conditions of uniform rotation of the crankshaft still grinding the neck of a diagram analysis, we found that controlling the abrasive in constant linear speed and constant pressure under the crankpin can achieve constant rate of removal. Then, when the abrasive is moving with constant speed under the crankpin, we analyses on the laws of crankshaft rotation and institutions movement, and simulates the equation of motion, Those curves are no mutations and to meet the engineering requirements. Finally, in order to ensure coordinate polishing crankshaft crankpin with abrasive tap with the polishing block clamping force, that is constant pressure grounding, so coordinate institutions must be analyzed counter weight. Those curves are no mutations and to meet the engineering requirements.
