Compensation mechanism for stress deformation of spindle box of machine tool

Abstract

The invention relates to a compensation mechanism for stress deformation of a spindle box of a machine tool, wherein the spindle box is arranged between two upright columns, thereby forming a gate-type thermal deformation symmetrical structure; two guide rails and sliding blocks are respectively arranged on front and back contact walls between the spindle box and the two upright columns, thereby forming a vertical guiding support; the compensation mechanism further comprises two compensation cylinders, two transition connection plates and two support shells; the two compensation cylinders are respectively arranged in the two support shells; the two support shells are symmetrically arranged at two sides of the upper end face on the rear part of the spindle box; two ends on one side wall of each transition connection plate are respectively connected to two sides of the upper end face on the rear part of the spindle box and corresponding to the sliding blocks of the guide rails; the two support shells, in which the compensation cylinders are arranged, are respectively arranged on the other side walls of the transition connection plates corresponding to the sliding blocks; and the piston rod ends of the compensation cylinders prop against the other side walls of the transition connection plates corresponding to the sliding blocks. According to the compensation mechanism provided by the invention, the deformation compensation mechanism is arranged inside a sliding sleeper. The compensation mechanism provided by the invention can be used for solving the problem of suspension stretching flexible deformation caused by the change of gravity center of a spindle component in the moving process of the spindle box and can be used for dynamically compensating the stress deformation generated by the spindle box in real time.

AI Technical Summary

Benefits of technology

This patented technology describes an improved design for a stressed or distorted portion (headstock) of a machine tool called Spinning Center®. It achieves this by adding extra guides along its length instead of just one single rail across each side. These guiding elements help prevent any bending moment from causing damage during machining operations without compromising their strength. Additionally, there may be multiple levels of damping within certain parts of the Stress Distortion Support System: One level includes three layers of steel plates arranged at different angles around the entire system's middle section. Another layer consists of conductive rubber disc springs placed under tension between these steel plats. Finally, another set of guide rails act like cushions against external forces such as impact loads. Overall, this innovative solution allows for precise and efficient correction of stress and displacement in the Headstock itself.

Problems solved by technology

This patents discuss how adding an external weight can help prevent distortion caused by changes in gravitational forces during operation of the machines' heads. However, current methods have limitations when trying to achieve this purpose.
