Motor-driven flange end surface processing tool

Abstract

The invention discloses a motor-driven flange end surface processing tool which comprises a fixing seat. A positioning clamping device, a rotating gear ring and a feeding gear ring are mounted on the fixing seat, the rotating gear ring is connected with a gear ring rotation driving device, a connecting seat which rotates along with the rotating gear ring is fixedly mounted on the rotating gear ring, a cutter radial propelling device is mounted on the connecting seat, a feeding power transmission is arranged between the cutter radial propelling device and the fixing seat, power of the feeding power transmission is converted into feeding power via the feeding gear ring, a cutting-feed adjusting device is mounted on the cutter radial propelling device, and a cutter is mounted on the cutting-feed adjusting device. The rotating gear ring drives the cutter to rotate, and power of the rotating gear ring is transmitted to the cutter radial propelling device via the feeding power transmission, so that the cutter is radially fed. The distance from the cutter to a workpiece can be adjusted via the cutting-feed adjusting device, so that the processing depth is controlled. The motor-driven flange end surface processing tool is simple in structure, wide in processing range, convenient to operate and low in manufacturing cost and is light, and the quality of flange end surfaces s processed by the tool meets national and international requirements on flange end surfaces.

Description

technical field [0001] The invention relates to a flange end face processing tool. Background technique [0002] In pressure vessels, tanks and pipelines, flanges are widely used workpieces. The end faces of these flanges require high roughness and flatness, and a considerable proportion of flange end faces have sealing line requirements. During the processing and installation of the flange, the end face of the flange often encounters bumps that cause damage to the sealing line; similarly, during the use of the equipment, the end face of the flange is prone to linear cavitation, which causes damage to the sealing line, resulting in seal failure and equipment failure. Leakage will affect the production operation; in case of the above situation, it is necessary to repair the sealing line of the flange end face, so as not to affect the sealing of the equipment. However, due to the small size of the sealing line, it is difficult to repair, so at present, it is often used to di...

Problems solved by technology

During the processing and installation of the flange, the end face of the flange often encounters bumps that cause damage to the sealing line; similarly, during the use of the equipment, the end face of the flange is prone to linear cavitation, which causes damage to the sealing line, resulting in seal failure and equipment failure. Leakage will affect the production operation; in case of the above situation, it is necessary to repair the sealing line of the flange end face, so as not to affect the sealing of the equipment

However, due to the small size of the sealing line, it is difficult to repair, so at present, it is often used to directly replace the new flange or cut off the existing flange and re-process it on a large boring and milling machine for repair, and then weld and install it. Repair by the above method, It is very easy to damage the sealing line caused by the collision of the flange end face again, and it is difficult, the repair of the flange sealing line takes a long time, the construction cost is high, and it is difficult to meet the installation accuracy requirements
