Nodular cast iron pipe inner wall surrounding grinding device

Abstract

The invention provides a surrounding polishing device for the inner wall of a nodular cast iron pipe, relates to the technical field of workpiece machining, and solves the problem that when an existing polishing device polishes the interior of the nodular cast iron pipe, polishing positions of the inner wall of the pipe body are uneven and deviate due to frequent sequential polishing. A surrounding grinding device for the inner wall of a nodular cast iron pipe comprises a fixing device, a limiting mechanism, a reciprocating mechanism, a clamping mechanism and a fixing mechanism, and a conduction mechanism is rotationally connected to the middle of the front end of the fixing device; The bottom of the limiting mechanism is fixedly connected to the middle of the top of the fixing device. Due to the fact that a conduction disc inserting column is located in a reciprocating groove, a whole reciprocating frame moves front and back through cooperation of a sliding rail and a sliding block, and when the grinding device grinds a steel pipe needing to be ground, the problem that the grinding position of the inner wall of the pipe body is uneven is solved.

Description

technical field [0001] The invention belongs to the technical field of workpiece processing, and more specifically relates to a surrounding grinding device for the inner wall of a nodular cast iron pipe. Background technique [0002] Ductile iron pipes refer to the pipes cast by high-speed centrifugal casting of centrifugal ductile iron machines after casting molten iron above No. 18 with the addition of nodularizers, referred to as ball pipes, ductile iron pipes and ductile cast pipes, etc. It is an ideal choice material for tap water pipelines. [0003] For example, application number: CN201810355648.9 The present invention relates to a cement inner wall grinding device for ductile iron pipes, which includes a track frame, a moving trolley, a supporting wheel set and a grinding rod assembly; two sides of the supporting wheel set are respectively provided with a The track frame and the mobile trolley; the mobile trolley is set on the track frame; a swing frame is arranged ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a device for grinding around the inner wall of ductile iron pipes, so as to solve the problem that when the existing grinding device is grinding the inside of ductile iron pipes, it is often polished sequentially, which will cause The problem of deviation in the unevenness of the wall grinding position
