Automatic drilling and tapping machine tool for valves

Abstract

The invention provides an automatic drilling and tapping machine tool for valves, which comprises a blanking mechanism, a workpiece locating mechanism, an automatic drilling mechanism, an automatic tapping mechanism, a workpiece clamping mechanism, a main clamping cylinder, a tapping mechanism feed cylinder, a drilling mechanism transmission lead screw, a workbench feed cylinder and a drilling mechanism feed servo motor. The blanking mechanism is perpendicularly disposed on a machine tool base, and the workpiece clamping mechanism is arranged at the bottom of the blanking mechanism and connected with the main clamping cylinder and the workbench feed cylinder. The automatic drilling mechanism comprises a pair of automatic drilling power heads which are coaxially and oppositely arranged. The automatic tapping mechanism is parallel to the automatic drilling mechanism in position and comprises a pair of automatic tapping power heads which are coaxially and oppositely arranged. The automatic drilling power heads are connected with the servo motor through the drilling mechanism transmission lead screw, and the automatic tapping power heads are connected with the cylinders. The automatic drilling and tapping machine tool for valves performs processing of four-station automatic drilling and tapping, processing of different parts can be achieved in one process, and production efficiency and product percent of pass are improved.

Description

Technical field [0001] The invention relates to the technical field of valve processing machinery, in particular to a valve automatic drilling and tapping machine tool. Background technique [0002] Valve is a control component in pipeline fluid transportation system, which has the functions of diversion, cutoff, regulation or overflow and pressure relief. [0003] Existing ordinary machine tools usually use a lathe clamping mechanism to clamp one end of the valve when processing the inner hole and thread of the valve, and drill and tap the other end. After the processing is completed, the two ends of the valve are exchanged. Drill and tap the unprocessed end until all parts of the valve that need to be processed are completed. As a result, the processing of the same valve requires multiple procedures, and multiple general-purpose machine tools are used to complete the processing. In each processing procedure, the valve body to be processed needs to be clamped and corrected. Espe...

AI Technical Summary

Problems solved by technology

In each processing procedure, the processed valve body needs to be clamped and corrected, especially for the processing of some larger-diameter valve bodies, it is necessary to replace a large lathe for processing, which increases the cost of machines and labor, and is time-consuming. Laborious, production efficiency and product qualification rate are greatly reduced
