Embodiment 1

[0037] refer to figure 1 , a flange end face processing method comprising 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, and at the same time drive the second tool with the second feed force from the inner edge to the outer edge of the flange end face in a circle ;

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

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

[0041] In this flange end face processing method, two cutters are used to process the flange end face, and the processing efficiency is high, and the cutting force and torque gen...

Embodiment 2

[0043] This embodiment provides a flange end face processing assembly based on the flange end face processing method in Embodiment 1, refer to figure 2 with 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 arranged coaxially, and one end of the central rotating shaft 7 is provided with a drive motor.

[0044] Further, the inner wall of the positioning frame 1 is evenly provided with a plurality of centripetal clamping parts 2, the flange is placed inside the positioning frame 1, and the clamping parts 2 can clamp the side of the flange, and fix the flange on the The midd...

Abstract

The invention discloses a flange end face processing method and a processing assembly thereof, wherein the flange end face processing assembly includes an annular positioning frame, a clamping piece, a first rotating arm, a first processing seat, a second rotating arm, a second processing The inner wall of the positioning frame is evenly provided with a plurality of centripetal clamping parts, the first rotating arm and the second rotating arm are respectively sleeved on the central rotating shaft, and the first rotating arm is provided with a first Tool, the second tool is set on the second rotating arm, the flange end face processing method and its processing components in the present invention use two cutters to process the flange end face, the processing efficiency is high, and the two cutters generate The cutting force and torque can offset each other, reducing the clamping burden of the flange, thereby reducing the vibration of the flange end face during processing, reducing the dimensional error of the end face, and ensuring the machining accuracy.

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 pipelines. 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 flange end face processing process is to fix the flange, use a tool to perform circular feed cutting on the flange end face, and perform progressive processing from the inner ring to the outer ring of the flange or from the outer ring to the inner ring. , and finally complete the machining of the entire end face of the flange, the machining efficiency is low, and due to the one-way machining of a tool, the flange is fixed and subjected to one-way c...
