Three-station combined machining tool for valve body of valve

Abstract

The invention discloses a three-station combined machining tool for a valve body of a valve, which comprises a tool bed and three swivel stands, wherein each swivel stand mainly comprises a tool rest mechanism, a speed shifting mechanism, a main spindle box, a feeding mechanism and a control system, the tool bed is provided with a fixture, the three swivel stands are respectively arranged at the left part, the middle part and the right part of the tool bed to form a triangular structure, the left and the right swivel stands are arranged in opposite directions and are same in structure, and the middle swivel stand is vertically downwards arranged on a column. Only by single clamping and correcting, the three-station combined machining tool can simultaneously machine a left-end flange, a right-end flange and a rabbet (or a watermark trough) of a valve body workpiece of a valve as well as the surface rabbet, the inner hole and the like of a mount support at the upper end of the valve body in three three-dimensional directions, and therefore, the labor intensity of workers is reduced, time and labor are saved, the production efficiency and the product machining qualification rate are improved, and economic benefits of valve production enterprises are increased.

Description

Technical field: [0001] The invention relates to a workpiece processing machine tool, in particular to a valve body workpiece processing machine tool, more specifically to a valve valve body three-station combined processing machine tool. The valve body processed by the present invention includes: check valve body, ball valve body, full-function regulating valve body, gate valve body, plunger valve body, butterfly valve body, steam trap valve body and diaphragm valve body Etc., the present invention of all the valve body parts of flange symmetrical layout at both ends can be processed. Background technique: [0002] Valves are the control elements in the pipeline fluid delivery system. They are used to change the passage section and medium flow direction, and have functions such as diversion, cut-off, adjustment, throttling, check, diversion or overflow relief. At present, domestic and foreign valve manufacturers usually use ordinary lathes or CNC machine tools to process v...

AI Technical Summary

Problems solved by technology

In this case, the processing of the same valve body must go through multiple processes and use multiple general-purpose machine tools to complete the processing. For clamping and calibration, especially for the flange processing of some large-diameter valve body parts, it is necessary to replace large-scale lathes, vertical lathes or boring machines for processing, which will inevitably increase the labor intensity of workers, waste time and effort, and reduce production efficiency and product processing. Qualification rate affects the economic benefits of production enterprises
