Conical seal welding type pipe joint port face polishing device

Abstract

The invention discloses a conical seal welding type pipe joint port face polishing device which comprises a device body, a second motor and a moving frame, an outer cover frame is arranged at the upper end of the device body, a hydraulic telescopic rod is arranged at the position, close to the rear side, of the upper end of the device body, meanwhile, the hydraulic telescopic rod is arranged on the inner side of the outer cover frame, and the front side of the hydraulic telescopic rod is connected with a first motor; and the first motor is connected with first rotating shafts, the first rotating shaft on the left side is connected with a mounting frame, the mounting frame is connected with a polishing disc, the first rotating shaft on the right side is connected with a polishing frame, and the second motor is arranged at the upper end of the device body. According to the conical seal welding type pipe joint port face polishing device, a second support is driven to rotate through a fourth motor and a third bevel gear set, the angle between the second support and the first support is adjusted, a placement frame on the first support is matched with a placement frame on the second support, bevel seal pipe joints at other angles are limited and fixed, and the machining range of the device is widened.

Description

technical field [0001] The invention relates to the technical field of welded pipe joints, in particular to a grinding device for the port surface of a cone-sealed welded pipe joint. Background technique [0002] Applicable media for welded pipe joints: non-corrosive or corrosive media such as oil, water, and gas. For welded sealed pipe joints, the specification requirements for matching steel pipes are relatively flexible. After welding with pipes, they have firm connection and good sealing performance, etc. Features, welded pipe joints mainly include flat seal joints and cone seal pipe joints. During the processing of cone seal pipe joints, the port surface of cone seal pipe joints needs to be polished and smoothed. Among them, the port surface of cone seal pipe joints has a cone part and a flat surface Most of the grinding devices for the port surface of the cone seal pipe joint can only grind the cone surface part or the plane part, and the cone seal pipe joint needs to ...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a grinding device for the port surface of a cone-sealed welded pipe joint, so as to solve the problem that most of the grinding devices for the port surface of the cone-sealed pipe joint proposed in the above-mentioned background technology can only grind the conical part or the plane part. Moreover, the existing grinding device for the cone-sealed pipe joint is inconvenient to adjust accordingly according to the inclination of the cone surface of the cone-sealed pipe joint
