AI Technical Summary

Technical Problem

Existing technologies for mass production of three-way valve bodies suffer from high equipment investment, high maintenance costs, difficulty in maintaining stable precision, and poor product consistency. In particular, they are unable to meet the high precision and standardization requirements of high-end operating conditions, especially in small and medium batch production scenarios.

Method used

Employing a multi-head milling machine, the system integrates multi-head collaborative operation with indexing and clamping design to achieve full-sequence machining of multiple processes such as valve body flange end face, side plane, drilling, boring of outer diameter and inner hole in a single clamping operation. Combined with high-precision indexing positioning and adaptive clamping structure, it ensures repeatability and positioning accuracy.

Benefits of technology

It significantly improves the machining accuracy and efficiency of valve bodies, reduces repeated clamping errors, lowers equipment procurement and maintenance costs, adapts to the automated production of valve bodies of different specifications, and improves the consistency of machining accuracy and equipment utilization.

Abstract

The application provides a valve body processing multi-head milling machine tool, and mainly relates to the field of valve body non-standard processing equipment. The valve body processing multi-head milling machine tool comprises a machine base, a first milling machine head, a drilling machine head and a second milling machine head with linear feeding modules arranged on the left side, the rear side and the right side of the machine base respectively, a feeding slide rail arranged on the front side of the machine base, a feeding drive mechanism arranged in the middle of the feeding slide rail, a feeding seat slidingly arranged on the feeding slide rail, a dividing and clamping seat arranged at the front end of the feeding seat, and a third milling machine head with a linear feeding module arranged at the rear end of the feeding seat. When the feeding seat moves into the machine base, the dividing and clamping seat is located at the center of the first milling machine head, the drilling machine head, the second milling machine head and the third milling machine head. The application has the beneficial effect that the application can complete the high-precision milling and drilling processing of the valve body in multiple faces and multiple processes at one time, and the cost is lower than that of the numerical control machining center equipment, thereby significantly reducing the equipment investment threshold of small and medium-sized manufacturing enterprises.
