AI Technical Summary

Technical Problem

The existing gantry frame is prone to bending and deformation due to the lack of support in the middle, which leads to a decrease in the accuracy of equipment movement and processing.

Method used

Reinforcing square tubes are installed inside the first crossbeam of the gantry frame, arranged in sections laterally and fixedly connected to the first crossbeam to increase support points and reduce bending deformation. A hollow structure is adopted to reduce self-weight, and the overall strength is improved by combining the second crossbeam and guide rails and other components.

Benefits of technology

By strengthening the support structure of the square tube, the deformation of the gantry frame was reduced, thereby improving the motion accuracy and machining accuracy of the equipment.

Abstract

The utility model relates to a kind of portal frame and machine tool, comprising: first crossbeam and reinforcing square tube, the cavity is formed in the first crossbeam inside, the first crossbeam extends horizontally, the reinforcing square tube extends longitudinally, the reinforcing square tube is inserted into first crossbeam longitudinally and is fixedly connected with first crossbeam.The first crossbeam of the utility model is divided into multiple segments by reinforcing square tube, the first crossbeam part of the lateral two sides of reinforcing square tube is different segment, the lateral two ends of segment are supported by support structure, and the lateral length of segment is shorter than first crossbeam, so the middle part of segment is more difficult to produce bending deformation due to external force or dead weight, the first crossbeam of multiple segments is also more difficult to produce deformation, and the movement accuracy of the drive mechanism installed on the first crossbeam is improved, and the machining accuracy of workpiece is finally improved.
