Automated assembly line for machining of valves

Abstract

The invention relates to an automated assembly line for machining of valves, and mainly solves the problems that when a connecting seat on a valve is machined by an existing general-purpose machine tool, repeated clamping is required, form and location tolerance is difficult to guarantee, quality of the valve is not easy to control, and machining efficiency is low. The automated assembly line for machining of valves is characterized in that an end surface milling power head (6), a boring power head (7), a groove milling power head (8) and drilling power heads (9) which are respectively mounted on a longitudinal sliding table (28) are successively arranged on the other side of a transverse numerical-control sliding table (2) from left to right, three V-shaped positioning plates (18) are fixed above a supporting seat (17), and a pneumatic lifting deflection clamp (19) is arranged on the supporting seat (17). The automated assembly line for machining of the valves is controlled by a PLC, can automatically convey and clamp the valves and machine various machining parts of connecting seats of the valves in order; and because machining is implemented by a disposable clamping assembly line, machining precision is guaranteed, the quality of the valves is easy to control, and machining efficiency is improved.

Description

technical field [0001] The invention relates to valve body processing automation equipment, in particular to a valve body machining automation assembly line. Background technique [0002] The valve body is the main part of the valve. Some large gate valve bodies and globe valve bodies are usually cast first, and then the valve body blanks are machined to meet the design requirements. The machining parts on the valve body blank that affect the assembly performance of the valve are: Figure 11 As shown, the valve body is provided with a connecting seat for installing the stem bracket, and the parts that need to be processed include the end face A of the connecting seat, the counterbore B, the annular groove C, and the bolt connection through hole D on the flange of the connecting seat. The above-mentioned processing parts usually use ordinary lathes, milling machines, drilling machines, boring machines and other machine tools. Since each machine tool is independent, it needs t...
