A Quantitative Control Method for Expansion Movement of Honing Machine

Abstract

The invention discloses a honing machine expansion movement quantitative control method. According to the honing machine expansion movement quantitative control method, an expansive force delta F of anumerical control honing machine is converted to a displacement amount delta L=delta F / C of a honing expansion ejector rod, wherein C is a conversion factor; and during honing processing, the honingexpansive force is ensured by controlling the displacement amount of the honing expansion ejector rod, and uniform-velocity processing under a certain expansive force is realized by controlling an expansion speed by a numerical control system. By adopting the honing machine expansion movement quantitative control method provided by the invention, by controlling converting the expansive force of the expansion movement of a honing machine in the prior art into the displacement amount of the honing expansion ejector rod, accurate and stable control over the honing force is realized, honing speedis uniform, and the accuracy of honing processing is ensured.

Description

technical field [0001] The invention relates to a method for controlling the expansion of a honing machine, which belongs to the technical field of honing machines, and in particular to a method for quantitatively controlling the expansion motion of a honing machine. Background technique [0002] The expansion movement of the honing machine is the key to ensure the quality of honing. Domestic honing machines are all manufactured with old-fashioned hydraulic control, and the expansion movement is realized by controlling the hydraulic pressure and flow value, the response speed is slow, and the processing quality is unstable. Foreign advanced honing machines all adopt numerical control system. By monitoring the power of the servo motor to monitor the expansion force, digital control of the expansion movement is realized, which has high processing speed and honing quality. However, the timing is scattered due to the untimely and unstable feedback of the expansion force control ...
