High-efficiency automatic pipe threading machine for heat preservation pipe production

Abstract

The utility model relates to the technical field of insulation pipe production, and specifically discloses an efficient automatic pipe threading machine for insulation pipe production, which comprises a base, an automatic centering mechanism and an outer pipe positioning mechanism are arranged above the base, the automatic centering mechanism comprises two positioning assemblies which are the same in structure, each positioning assembly comprises a U-shaped frame fixedly connected to the upper end of the base, a bidirectional screw rod is rotatably connected to the inside of the U-shaped frame, two symmetrically distributed sliding sleeves are threadedly connected to the outer wall of the bidirectional screw rod, the upper end of one of the sliding sleeves is fixedly connected with a mounting frame, and the guide wheel contacts the inner pipe to extrude the pressure sensor, the motor stops rotating when the threshold value is reached, a "cross type" clamping structure is formed to center the inner pipe, the outer pipe axis is ensured to coincide, manual intervention is not needed throughout the process, the pipe threading efficiency is improved, accurate centering is achieved, the product quality is ensured, and the production flexibility is enhanced.
