Abstract

The invention discloses multi-shaft precise linkage feeding equipment. The equipment comprises two independent lifting shafts which are fixed on a fixed bracket, wherein a lifting slide is driven to move vertically on the lifting shafts along a V-shaped guide rail by a motor through a screw and is provided with a workbench positioning workpiece; a portal type cross slide is arranged above the workbench and is driven to link longitudinally and transversely by the motor; and an independent miniature lifting shaft capable of moving along the vertical direction is arranged on the cross slide, anda processing tool is fixed on the lower end of the independent miniature lifting shaft. According to the feeding equipment, detection and compensation of motion accuracy of the multi-shaft linkage equipment are ensured, and the positioning accuracy between the processing workpiece and the processing tool is improved.

Description

technical field [0001] The invention relates to a multi-axis linkage precision equipment, especially for feeding equipment in the field of advanced manufacturing. Background technique [0002] The degree of advancement of multi-axis precision linkage equipment directly reflects the development status of the country's manufacturing industry. At present, the common linkage equipment in most machinery manufacturing mechanical systems, such as multi-axis lifting or sliding platforms, are directly driven by screw screws, and the motion shaft is directly set on the guide rail. In this driving form, the lead screw is used as the feeding part of the lifting platform. Although it can convert the rotary motion into a linear motion, the installation and fixation of the lead screw is not easy to achieve; the overall feed system composed of the motor drive and the lead screw lacks feedback. Information makes it difficult to guarantee positioning accuracy, especially for precision manufa...
