Machining automatic assembly line for inlet and outlet connecting flange on valve body

Abstract

The invention relates to a machining automatic assembly line for an inlet and outlet connecting flange on a valve body. The problems that an import and export connecting flange on an existing common machine tool machining valve body needs to be mounted and clamped for multiple times, form and location tolerance is difficult to guarantee, the valve body quality is not easy to control, and the machining efficiency is low are mainly solved. The automatic assembly line is characterized in that symmetrical end face milling power heads (6), symmetrical boring end face power heads (7) and symmetrical drilling power heads (8) are sequentially arranged on the two sides of a tool body (1); and a fixed V-shaped clamping plate (17) and a sliding V-shaped clamping plate (18) are oppositely arranged on a positioning flat plate (16). The machining automatic assembly line can automatically convey and mount and clamp the valve body and machine all the machining parts of the inlet and outlet connection flange on the valve body in sequence, the machining accuracy is guaranteed, the valve body quality is easy to control, the machining efficiency is increased, and all machining parts on the valve body can be completed at one time by the matching use of the automatic assembly line and a valve body machining automatic assembly line for machining a connecting seat on the valve body.

Description

technical field [0001] The invention relates to valve body processing automation equipment, in particular to an automatic assembly line for mechanical processing of valve body inlet and outlet connection flanges. Background technique [0002] The valve body is the main part of the valve. Some large gate valve bodies and globe valve bodies are cast and formed first, and then the valve body blanks are machined to meet the design requirements. The parts on the valve body that need to be machined are as follows: Figure 11 As shown, the valve body is equipped with a connecting seat for installing the valve stem bracket and a connecting flange for the inlet and outlet of the valve body. The parts that need to be processed include the end face of the connecting seat, the counterbore, the annular groove and the bolt connection through hole on the flange of the connecting seat. In addition, it is necessary to machine the flange end face A, the flange sinking end face B and the throu...
