Embodiment 1

[0037] refer to figure 1 , a flange end face processing method includes the following steps:

[0038] S1: Drive the first tool with the first feed force from the outer edge to the inner edge of the flange end face in a circle, while driving the second tool with the second feed force in a circle from the inner edge to the outer edge of the flange end face ;

[0039] S2: During the machining process, keep the torque of the first tool to the center of the flange end face equal to the torque of the second tool to the center of the flange end face, and in opposite directions;

[0040] S3: When the first tool and the second tool are on the same ring to be processed on the flange end face, one of the tools is retracted, and the other tool completes the processing of the flange end face.

[0041] In this flange end face machining method, two tools are used to process the flange end face, which has high processing efficiency, and the cutting force and torque generated by the two tool...

Embodiment 2

[0043] This embodiment provides a flange end face machining component based on the flange end face machining method in Embodiment 1. Refer to figure 2 and image 3 , the flange end face processing assembly includes a frame on which an annular positioning frame 1 , a first rotating arm 3 , a first processing seat 4 , a second rotating arm 5 , a second processing seat 6 and a central rotating shaft 7 are arranged. Specifically, the positioning frame 1 is fixedly connected to the frame, the central rotating shaft 7 is rotatably connected to the frame, the positioning frame 1 and the central rotating shaft 7 are coaxially arranged, and one end of the central rotating shaft 7 is provided with a drive motor.

[0044] Further, a plurality of centripetal clamping members 2 are evenly arranged on the inner wall of the positioning frame 1, the flange is placed inside the positioning frame 1, and the clamping members 2 can clamp the side of the flange and fix the flange on The middle o...

Abstract

The invention discloses a flange end face machining method and a flange end face machining assembly. The flange end face machining assembly comprises an annular positioning frame, clamping pieces, a first rotating arm, a first machining seat, a second rotating arm, a second machining seat and a center rotating shaft, the plurality of centripetal clamping pieces are evenly arranged on the inner wall of the positioning frame, the first rotating arm and the second rotating arm are connected to the central rotating shaft in a sleeving mode, a first cutter is arranged on the first rotating arm, and a second cutter is arranged on the second rotating arm. According to the flange end face machining method and the flange end face machining assembly, the two cutters are used for machining a end face of a flange, the machining efficiency is high, meanwhile, cutting force torques generated by the two cutters to the flange can be mutually counteracted, the clamping burden of the flange is reduced, and therefore shaking of the end face of the flange in the machining process is reduced, the size error of the end face can be reduced, and the machining precision is guaranteed.

Description

technical field [0001] The invention relates to the technical field of flange processing, in particular to a flange end face processing method and a processing component thereof. Background technique [0002] Flanges are parts that connect pipes to pipes, or pipes to equipment outlets, and are widely used in pressure vessels, tanks and pipes. The end face of the flange is often used as a sealing surface. In the process of flange processing, end face processing is a necessary process for flange processing. [0003] The general process of flange end face processing is to fix the flange, use a tool to perform circular feed cutting on the flange end face, and perform incremental processing from the inner ring of the flange to the outer ring or from the outer ring to the inner ring. , and finally complete the processing of the entire end face of the flange, the processing efficiency is low, and due to the one-way processing of a tool, the flange is subjected to one-way cutting f...
