Abstract

The invention discloses a numerical control band sawing machine with correction devices. An existing band sawing machine has the problem that in the saw cutting process, because of sawing band deflection and deformation, the workpiece saw cutting precision is reduced. By means of a clamping mechanism of the numerical control band sawing machine, a workpiece is clamped on a working table; a driving sawing band wheel and a driven sawing band wheel are installed on a saw frame; a sawing band is connected with the driving sawing band wheel and the driven sawing band wheel and is tensioned by a tensioning mechanism; a main movement servo motor drives the driving sawing band wheel; a feeding servo motor drives a feeding mechanism so that the saw frame can be driven to move up and down for feeding; and the two sawing band guide and correction devices are installed in the saw frame. By means of a lead screw and nut transmission mechanism driven by a servo motor, micro displacement is achieved; and by means of a worm and gear speed reducer driven by the servo motor, micro swinging is achieved. By means of two transmission mechanisms, two-freedom-degree linkage of rotation and horizontal movement is achieved for guide blocks, the problem that in the saw cutting process of the existing band sawing machine, because of sawing band deflection and deformation, the workpiece saw cutting precision is reduced is solved, and the saw cutting precision is greatly improved.

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 deviation correcting device, which is used for 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 will deviate and deform due to uneven material of the workpiece, wear of the moving parts of the machine tool, and changes in operating parameters during the sawing process, causing the workpiece Sawing accu...
