Numerical control band sawing machine with vibration attenuation and deviation rectification control device

Abstract

The invention discloses a numerical control band sawing machine with a vibration attenuation and deviation rectification control device. An existing band sawing machine tool has the problems that a saw band vibrates, deviates and deforms, and consequently the workpiece saw cutting quality is lowered. A clamping mechanism clamps a workpiece to a workbench of a machine body. A saw band is tightened through a tightening mechanism. A main movement servo motor drives a drive saw band wheel. A feeding servo motor drives a feeding mechanism so as to drive a saw frame. Two deviation rectification devices are provided with eddy current displacement sensors for detecting displacement of the two ends of the saw cutting part of the saw band and inputting the detection result into a control module for calculating the vibration value and the saw cutting error of the saw band. The tightening mechanism, the deviation rectification devices and a vibration attenuation device are all controlled by the control module. By the adoption of the numerical control band sawing machine with the vibration attenuation and deviation rectification control device, according to the detection result of saw band vibration, the vibration attenuation device and the tightening mechanism are jointly controlled, and vibration is eliminated; and according to the detection result of the saw band movement error, automatic adjustment is achieved through the deviation rectification devices, so that the saw cutting accuracy and surface quality are improved greatly.

Description

technical field [0001] The invention belongs to the technical field of mechatronics, and in particular relates to a numerically controlled band sawing machine with a vibration elimination and deviation correction control device, which is used for vibration elimination and error compensation of the band saw during the sawing process. Background technique [0002] CNC band saw equipment is one of the preferred equipment for the initial processing of parts in modern machinery manufacturing industries such as automobiles, aircraft and ships. The processing accuracy, efficiency, reliability and degree of automation of this equipment directly affect the production efficiency and quality of the entire parts . Since the sawing tool of the CNC band sawing machine is a saw band, that is, a flexible tool, it is inevitable that the saw band vibrates (chatter) and travels due to uneven workpiece material, wear of the moving parts of the machine tool, and changes in operating parameters d...
