Abstract

The present application provides a thermal deformation compensation mechanism for the ram spindle of a boring and milling machine, which includes a grating scale displacement sensor fixedly arranged on the inner wall of the slide plate; a thermal standard element fixedly arranged in the ram; The grating scale line displacement reading head that is fixedly connected with the thermal standard element; when the grating scale line displacement reading head moves under the drive of the thermal standard element to generate readings, the control system can according to the The readout controls the ram to perform compensating motion. The present application provides a thermal deformation compensation mechanism and method to transfer the thermal elongation deformation of the front end of the ram to the linear displacement reading head of the grating ruler. The linear displacement reading head of the grating scale and the displacement sensor of the grating scale generate the movement value and feed it back to the control system, so that the control system can control the servo motor to adjust the position of the ram, and realize the compensation for the thermal deformation of the main shaft of the ram.

Description

technical field [0001] The invention and the field of numerically controlled machine tools particularly relate to a thermal deformation compensation mechanism and a compensation method for a thermally deformed main shaft of a ram main shaft of a boring and milling machine. Background technique [0002] At present, the factors affecting the machining accuracy of CNC machine tools can be summarized into four categories: geometric errors of the main mechanical structure of machine tools; load errors during processing; thermal deformation errors; servo system control errors. A large number of studies have shown that thermal deformation in precision machining has become a key factor affecting the stability of machining accuracy, and the machining error caused by it accounts for as high as 40% to 70% of the total error. [0003] CNC machine tools are affected by various heat sources such as frictional heat, cutting heat, and room temperature changes during the working process. The...
