Abstract

The invention relates to an automatic PPR pipe fusion-welding robot and a fusion-welding method, which belong to the field of pipe fusion-welding and intelligent control, and aim to solve the problemsthat the manual fusion-welding of a PPR pipe is affected by the manual operation strength, a pipe propelling angle, the environment temperature, the processing time and other factors. The automatic PPR pipe fusion-welding robot comprises a base, wherein a die head clamping unit capable of heating different types of die heads is arranged in the middle of the upper part of the base; pipe clamping units are arranged on two sides of the die head clamping unit; fixtures are arranged on the pipe clamping units and are used for clamping pipes with different specifications; a laser transmitter and alaser receiver are arranged on the fixtures; and a single chip microcomputer drives a screw rod to feed along a guide rail, so that the automatic fusion-welding operation with the best fusion-weldingtemperature, heating time, hot-melting depth and fusion-welding time is realized. According to the automatic PPR pipe fusion-welding robot and the fusion-welding method provided by the invention, theautomatic fusion-welding of pipes and pipe fittings with different specifications can be realized, and the fusion-welding is carried out at the best time, temperature and position, the reliability offusion-welding is ensured, and the fusion-welding efficiency is improved.

Description

technical field [0001] The invention relates to an automatic PPR pipe welding robot and a welding method of the welding robot, belonging to the field of pipeline welding and intelligent control. Background technique [0002] PPR pipes are widely used in building water supply and drainage, urban and rural water supply and drainage, industrial fluid transportation, agricultural irrigation, etc. , industry and agriculture. At present, PPR pipe hot-melt tools on the market are generally fully manual operations. The pipe is manually pushed into the heating die of the fusion splicer. With the experience of the operator, the pipe is removed from the die at the same time as soon as the processing time is reached, and then manually quickly and seamlessly. Evenly inserted to the desired depth while rotating, the welding is completed. This manual method is affected by factors such as human operating force, pipe propulsion angle, ambient temperature, processing time, etc., resulting i...
