Welding pipe groove grinding device

Abstract

The invention provides a welding pipe groove grinding device. The problem that the welding quality is affected due to uneven grinding of a groove of existing grinding equipment is solved. The groove grinding device comprises a supporting table and a welding pipe, wherein a propelling mechanism is arranged on the supporting table, the propelling mechanism comprises a first hand wheel, a bearing block, a sliding rail, a first screw rod, a sliding support, a supporting plate and a support, the bearing block is fixed at one end of the supporting table, the support is fixed at the other end of thesupporting table, one end of the first screw rod penetrates through the bearing block to be rotationally connected to the support, the first hand wheel is fixed on the other end of the first screw rod, the sliding support is in threaded connection with the first screw rod, the supporting plate is fixed on the sliding support, a clamping mechanism is arranged on the supporting plate, and a grindingdevice is arranged on the support. According to the welding pipe groove grinding device, the operation is simple, the use is convenient, the welding groove can be ground smooth and uniform, and the welding quality can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and relates to a bevel grinding device, in particular to a welded pipe bevel grinding device. Background technique [0002] Welded pipe refers to pipe fittings that are connected to pipes by welding. When welding some welded pipes with large wall thickness, in order to ensure the welding quality and the appearance of the weld seam, the welding end of the pipe fittings is usually welded with a bevel. The common way to make the bevel is to use lathe turning or manual grinding , Usually the construction conditions are relatively simple, no lathe can be used, and manual grinding with a grinder is time-consuming and laborious, and the groove produced by grinding is not smooth, which affects the welding quality. [0003] After searching, for example, Chinese patent literature discloses a bevel grinding device for pipe fittings [application number: CN201820219875.4; publication number: CN2080...

AI Technical Summary

Problems solved by technology

[0004] A pipe bevel grinding device disclosed in this patent can solve the problem of rapid bevel grinding of pipe fittings, but the device installs the pipe vertically on the clamping mechanism for grinding, and the operation is cumbersome. The arm is tightened to clamp pipe fittings of different sizes. This clamping method is less stable, and it will shake during the grinding process, resulting in uneven grinding of the groove and affecting the welding quality.
