Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, in particular to an internal diameter planing machine for plastic pipelines. Background Technique

[0002] At present, some plastic pipelines are connected by welding. The specific process is to heat and melt the end faces to be connected of two sections of plastic pipelines and then press them together. After cooling, the connection is fixed. When plastic pipelines are connected by the above welding method, due to the extrusion of the molten material to the inside and outside, a ring-shaped protrusion that protrudes from the inner and outer surfaces of the pipe body will appear at the connection, which needs to be removed. Among them, the removal of the ring-shaped protrusion on the outer surface is relatively convenient. However, for the ring-shaped protrusion on the inner surface, since it is difficult for human hands to reach, generally a planing robot is used for planing and removing.

[0003] For example, the Chinese patent with the application number CN202022349135.2 discloses an internal diameter planing machine for plastic pipelines, which includes a support plate. The left end of the top of the support plate is fixedly connected with a vertical plate. The right side of the vertical plate is fixedly connected with a first motor. The outer surface of the main shaft of the first motor is fixedly connected with a first coupling. The inner surface of the first coupling is fixedly connected with a first telescopic rod. The inner surface of the first telescopic rod is movably connected with a second telescopic rod. The right end of the second telescopic rod is fixedly connected with a planing head. The support plate is provided with an inner cavity, and the left end of the inner bottom wall of the inner cavity is fixedly connected with a second motor. For this internal diameter planing machine for plastic pipelines, by moving the fixed cylinder to the left, the problem of small impact force during planing is solved. After the planing head finishes planing the pipeline, a grinding head is used to grind the inner wall of the pipeline to ensure that the inner wall of the pipeline is smooth. Therefore, the planing head is mostly fixed on the moving part in a detachable installation manner. To ensure stable planing, the planing head is very firmly fixed to the moving part, which brings difficulties to the grinding head. Summary of the Utility Model
