Abstract

The invention relates to a turning clamp for a blind flange, and relates to the technical field of metal machining equipment. The turning clamp for the blind flange comprises a base plate, a first pressing mechanism and a second pressing mechanism, wherein the first pressing mechanism comprises a tailstock and a tail cone; the tail cone is rotatably connected onto the tailstock; the tail cone and the base plate are coaxially arranged; the base plate is coaxially and fixedly connected onto a main shaft of a lathe; the second pressing mechanism comprises a clamping jaw; and the clamping jaw is connected onto the base plate in a sliding mode. According to the turning clamp for the blind flange provided by the invention, when the peripheral face of a workblank is machined, the base plate and the tail cone are used for clamping the workblank, so that the peripheral face of the workblank can be completely exposed outside; and when a boss of theworkblank is machined, the workblank is clamped by the base plate and the clamping jaw, so that the axis part of the workblank can be completely exposed outside, and feeding of a turning tool is facilitated.

Description

technical field

[0001] The present application relates to the field of metal processing equipment, in particular to a turning fixture for a flange blind plate. Background technique

[0002] Blind flange, also known as blind flange, is a form of flange and can be understood as a flange without a hole in the middle. The function of the flange blind plate: one is to block the end of the pipeline, and the other is to facilitate the removal of debris in the pipeline during maintenance. As far as the plugging effect is concerned, it has the same function as the head and the pipe cap, but the head cannot be disassembled, and the flange blind plate is fixed with bolts, which is very convenient to disassemble.

[0003] refer to Figure 6 , the flange blind plate 600 includes a plate body 610 and a boss 620 coaxially arranged on the plate body 610. During the transfer process, the boss 620 plays a role in separating the flange blind plate 600, so that the two flanges are not easy to ...
