Rigidity design method for double-rail six-sliding-block rolling guide rail pair

Abstract

The invention discloses a rigidity design method for a double-rail six-sliding-block rolling guide rail pair, and belongs to the technical field of machine tools. The method comprises the steps that firstly, the load torque of the rolling guide rail pair is calculated; the normal loading force and the lateral loading force of each sliding block are further deduced; the deformation of the supporting tail end of the rolling guide rail pair is calculated; finally, the rigidity design of the double-rail six-sliding-block rolling guide rail pair is completed according to the supporting tail end deformation constraint relation. According to the method, the system load and the supporting tail end deformation constraint are fully considered, the problems that a traditional method depends on experience, is low in efficiency and is inaccurate are solved, rapid and accurate design of the rigidity of the double-rail six-sliding-block rolling guide rail pair is achieved, and an accurate and convenient design method is provided for field engineering technicians. Moreover, the method has the advantages of process and standardization, and can be conveniently and quickly popularized in practical engineering application.

Description

technical field [0001] The invention belongs to the technical field of machine tools, and in particular relates to a stiffness design method for a double-track six-slider rolling guide pair. Background technique [0002] The rolling guide pair is used to support the worktable to complete high-precision linear motion. It is an important basic functional part in the field of CNC machine tools, and each guide rail of the double-track six-slider rolling guide pair has three sliders evenly distributed on each guide rail. A widely used type of rolling guide pair. Stiffness is the core parameter of the rolling guide pair. In the process of using the rolling guide pair, it is necessary to design the stiffness reasonably to meet the performance requirements at a lower cost. In practical engineering applications, how to design a reasonable stiffness for the double-track six-slider rolling guideway pair has become a key issue that needs to be solved urgently. [0003] The stiffness d...
