Abstract

The invention relates to a high-frequency induction brazing deep elbow pipe welding line polishing device. One end of a bearing sleeve is connected with a soft shaft through a transmission shaft, the other end of the bearing sleeve is connected with a knife clamping disc, and a knife is arranged on the knife clamping disc. Three pairs of ear pieces which are distributed evenly in a periphery mode are arranged on a stepped shaft. A sliding block is in axial connection with the transmission shaft. Three pairs of ear pieces are distributed evenly on the inner surface of the sliding block. A supporting locating mechanism of a three-connecting-rod structure is connected between each sets of corresponding ear pieces of the sliding block and the bearing sleeve. A supporting sleeve is arranged on the bearing sleeve. Three pairs of ear pieces on the supporting sleeve are connected with connecting rods respectively. The other ends of the connecting rods are connected with connecting shafts above the supporting locating mechanism. A guiding pressing spring is arranged on the outer side surface of the sliding block. The other end of the guiding pressing spring is in contact with a supporting piece. A pulling wire penetrates through the supporting piece and the sliding block and then is connected with the support sleeve. A reset spring is arranged on the outer periphery of the pulling wire. The two ends of the reset spring are in contact with the supporting sleeve and the sliding block respectively. A pulling wire self-locking device is arranged on the end portion of the pulling wire. The polishing device can effectively polish a brazing overlap in an elbow pipe, using is convenient, maintaining is easy, and the polishing device is not limited by pipe models.

Description

technical field [0001] The invention relates to a welding seam grinding device for high-frequency induction brazing deep bend pipes, which is mainly used for grinding internal weld seams of high-frequency induction brazing deep bend pipes. Background technique [0002] At present, after high-frequency induction brazing, welding defects such as welding burrs generated inside deep-bent pipe fittings cannot be removed by grinding with existing tools. In terms of production, the method of reheating the solder to reshape the weld is mainly used to improve, but The effect is not obvious, and the group efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-frequency induction brazing deep elbow weld seam grinding device, which can effectively grind the inner brazing weld of the elbow, easy to use, easy to maintain, and not limited by the pipe type . [0004] In order to solve the above problems, the...
