Pipe center alignment mechanism and method for ship tail pipe

Abstract

The invention relates to a pipe center alignment mechanism and a method for a ship tail pipe, which belongs to the field of marine manufacturing equipment. The pipe center alignment mechanism for a ship tail pipe comprises an adjusting ring and an adjusting screw. The adjusting ring is provided with the adjusting screw in the radial direction. A centering seat is provided at the center of the adjusting ring. The centering seat is provided with a fixing shaft. A conversion shaft is provided in the fixing shaft. A target frame is provided on the conversion shaft. The axial direction of the conversion shaft is provided with a laser line with respect to the tail pipe. A dial gauge is provided on the target frame. The adjusting ring is provided in the inner wall of the tail pipe by the adjusting screw. In the pipe center alignment mechanism for a ship tail pipe, the original steel wire is replaced by the laser line, and the inner diameter micrometer is replaced with an adjustable target center and is equipped with a dial indicator, thereby simplifying a measuring device and increasing the measurement accuracy. In addition, the invention is simple in operation, and can be adjusted by a single person in a short time.

Description

technical field [0001] The invention relates to a tube center centering mechanism and a centering method for a ship stern tube, belonging to the field of marine manufacturing equipment. Background technique [0002] During the inspection process of the ship stern tube shafting cable, the stern tube centering tolerance is required to be high. The use of steel wires with inner diameter micrometers requires experienced masters. The professional requirements are high, and the data is not intuitive and accurate enough. [0003] The activity space of the ship's engine room is relatively compact. If the 1mm steel wire is straightened, it is easy to trip the construction workers if you don't pay attention to it, posing unsafe risks. Contents of the invention [0004] The present invention provides a tube center centering mechanism and a centering method for a ship's stern tube aiming at the above disadvantages. [0005] The present invention adopts following technical scheme...
