AI Technical Summary

Technical Problem

The existing casting pouring and riser cutting and grinding equipment has poor flexibility and insufficient bearing capacity, making it difficult to meet the high-efficiency cutting requirements of large pouring and risers.

Method used

A high-stiffness gantry hybrid machine tool for casting pouring riser cutting and grinding is designed. Through the combination of gantry, sliding sleeve, sliding drive part, telescopic arm and tool holder, the sliding rail structure of the sliding sleeve U-shaped sliding saddle and cross beam is used to achieve the height adjustment of the tool holder and the precise control of the tool head position, dispersing the overall weight, and improving the stiffness and load bearing capacity.

Benefits of technology

It improves the overall stiffness and bearing capacity of the machine tool, enhances the stability of the structure, extends the service life of the slide rail and the slide sleeve, and meets the high-efficiency cutting needs of large pouring risers.

Abstract

The invention discloses a high-rigidity gantry type hybrid machine tool for cutting and grinding a casting head of a casting, and relates to the technical field of casting cutting and grinding equipment. The device comprises a portal frame, a sliding sleeve, a sliding driving part, a telescopic arm and a tool apron. The portal frame comprises a cross beam and stand columns supported at the two ends of the cross beam. An upper sliding rail arranged in the length direction is fixedly installed on the upper surface of the cross beam, and side sliding rails arranged in the length direction are symmetrically installed on the two side walls of the cross beam. The sliding sleeve comprises a U-shaped upper sliding saddle, a U-shaped lower sliding saddle and a connecting piece used for connecting the upper sliding saddle and the lower sliding saddle, wherein the upper sliding saddle and the lower sliding saddle can be buckled with each other. The sliding sleeve can slide in the length direction of the cross beam to adjust the position of the telescopic arm, and then the height of the tool apron is adjusted through the telescopic amount of the telescopic arm; the sliding sleeve is formed by connecting the upper saddle and the lower saddle, a load part of the sliding sleeve is borne by the upper saddle and the upper sliding rail, the other load part of the sliding sleeve is borne by the lower saddle and the side sliding rail, the overall rigidity and bearing capacity of the sliding sleeve are improved, the structural stability is enhanced, and the service life of the sliding rail and the sliding sleeve is prolonged.
