Flange machining tool

Abstract

The invention relates to a flange machining tool which comprises a bolt, a pressing block, a template, a workpiece and a nut, wherein the head part of the bolt is embedded in a transverse groove in the machining surface of a drilling machine, and a screw rod of the bolt is vertically arranged on the machining surface of the drilling machine, passes through a central through hole in the workpiece and is closely clung to the machining surface of the drilling machine; the size of the circular template is equal to that of the workpiece, the central part of the circular template is provided with a through hole, the diameter of the through hole is larger than that of the screw rod of the bolt, and the screw rod of the bolt passes through the through hole in the template, so that the position of the template is over against that of the workpiece; the central part of the trapezoidal pressing block is provided with a through hole, and the diameter of the through hole is larger than that of the screw rod of the bolt; and the pressing block is clamped above the template and the nut is fixed above the pressing block in a threaded connection manner. The flange machining tool disclosed by the invention has the advantages of greatly shortening the working hour, improving the working efficiency, greatly reducing the expenditure of personnel and supplies and motivating the production activeness of assembly personnel.

Description

technical field [0001] The invention relates to a tool, in particular to a tool for processing flanges. Background technique [0002] Flanges are also called flanges or flanges. They are usually used in pairs, especially in pipeline engineering. The flange connection consists of a pair of flanges, a gasket and several bolts and nuts. The gasket is placed between the sealing surfaces of the two flanges. After the nut is tightened, the specific pressure on the surface of the gasket reaches a certain value and then deforms, and fills up the unevenness on the sealing surface to make the connection tight. Some pipe fittings and The equipment has its own flange, which is also a flange connection. However, with the gradual improvement of social science and technology, ordinary flanges are increasingly unable to meet the needs of production and life, and flanges with special functions are gradually appearing in people's production and life. Due to different occasions, the materials...
