Problems solved by technology

[0002] After the existing pipeline is welded, the inner wall of the pipeline will have defects such as welding bumps, welding slag and rust spots. If these defects are directly put into use without grinding, the quality of the conveying product will be seriously affected. It will accelerate the corrosion of the pipeline and shorten the service life of the pipeline system. Therefore, it is necessary to provide a device that can grind the inner wall of the pipeline

Abstract

The invention discloses a pipe inner wall variable-diameter grinding device which comprises a variable-diameter grinding mechanism, a revolution drive member, a front displacement support mechanism, afront grinding support mechanism, a rear displacement support mechanism and a rear grinding support mechanism. The front displacement support mechanism and the front grinding support mechanism are arranged at one end of the variable-diameter grinding mechanism, and the rear displacement support mechanism and the rear grinding support mechanism are arranged at the other end of the variable-diameter grinding mechanism; the variable-diameter grinding mechanism is used for grinding the pipe inner walls; and the front displacement support mechanism and the rear displacement support mechanism alternately provide axial displacement for the variable diameter grinding mechanism, and the front grinding support mechanism and the rear grinding support mechanism are used for providing radial supporting force. By means of the pipe inner wall variable-diameter grinding device, the front grinding support mechanism and the rear grinding support mechanism are used for supporting the variable-diameter grinding mechanism, the variable-diameter grinding mechanism adjusts the action radii according to pipes with different pipe diameters, rotation is carried out under driving of the revolution drive member, weld beading, welding slag and rust spots on the pipe inner walls are ground to form a smooth surface, and the front displacement support mechanism and the rear displacement support mechanism alternately provide the axial displacement to complete grinding of the entire pipe inner walls.

Description

technical field [0001] The invention relates to the technical field of grinding equipment, in particular to a pipe inner wall variable diameter grinding device. Background technique [0002] After the existing pipeline is welded, the inner wall of the pipeline will have defects such as welding bumps, welding slag and rust spots. If these defects are directly put into use without grinding, the quality of the conveying product will be seriously affected. It will accelerate the corrosion of the pipeline and shorten the service life of the pipeline system. Therefore, it is necessary to provide a device capable of grinding the inner wall of the delivery pipeline. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings, and provide a pipe inner wall variable diameter grinding device. [0004] To achieve the above object, the specific scheme of the present invention is as follows: [0005] A pipe inner wall variable...
