AI Technical Summary

Technical Problem

During the casting process, burrs are easily generated on the curved parts of the pipe fitting surface, resulting in an uneven surface that affects assembly accuracy and sealing performance.

Method used

A casting surface treatment device was designed, comprising a base frame, a support platform, a support plate, a cylinder, a straightening head, a pipe fixing mechanism, and an adjustable grinding mechanism. The straightening head is driven by the cylinder to correct the bent parts of the pipe, and the pipe fixing mechanism and the adjustable grinding mechanism are used to remove burrs, ensuring that the surface of the pipe is flat.

Benefits of technology

It effectively improves the flatness of the pipe fitting surface, reduces friction and wear during assembly, and improves the fitting accuracy and sealing performance between the pipe fitting and other components.

Abstract

The utility model belongs to the technical field of casting surface treatment, and particularly discloses a casting surface treatment device for precision casting, which comprises a base frame, a support table is fixedly mounted on the inner side of the base frame, a table shaft is fixedly arranged on the inner side of the support table in a penetrating manner, and a support plate is rotatably connected to the outer surface of the table shaft. An air cylinder is fixedly installed on the top of the base frame, the output end of the air cylinder is fixedly connected with a shape correcting head, a pipe fixing mechanism is arranged on the base frame, and one end of the base frame is fixedly connected with a fixing base. According to the casting surface treatment device for precision casting, after a bent part of a pipe fitting is subjected to shape correction at a correct position on a supporting plate through cooperation of an air cylinder and a shape correction head, deburring treatment can be conducted on the two groups of the pipe fitting subjected to shape correction through a pipe fixing mechanism and an adjustable grinding mechanism, the flatness of the surface of the pipe fitting is effectively improved, and the machining efficiency is improved. Friction and abrasion during assembly are reduced due to the flat surface, and the matching precision and the sealing performance of the pipe fitting and other components are improved.
