A ship fitting installation alignment and positioning device

Abstract

This utility model discloses a ship accessory installation alignment and positioning device, including a first support frame, a stern shaft clamping mechanism at the upper end of the first support frame, and a second support frame on the ground to the right of the first support frame. This utility model adjusts the position between two sets of clamping blocks by activating a second hydraulic cylinder to move the propeller clamping mechanism downwards, and then by driving a bidirectional lead screw to rotate via a second motor. This allows the two sets of clamping blocks to clamp the propeller, placing the stern shaft inside the first and third V-shaped grooves. Then, the first hydraulic cylinder is activated to press down the second V-shaped groove, clamping and securing the stern shaft with the cooperation of the second and first V-shaped grooves. Finally, the first motor drives the lead screw to rotate, adjusting the left and right position of the propeller to assemble it with the stern shaft. The propeller position is adjusted according to the installation situation, making the overall assembly process more stable and convenient.

Description

Technical Field

[0001] This utility model relates to the field of ship parts installation technology, and in particular to a ship parts installation alignment and positioning device. Background Technology

[0002] A ship is a man-made means of transportation that primarily operates in water. Its shape is generally a streamlined envelope that helps overcome fluid resistance. Materials used are constantly evolving with technological advancements; early ships used natural materials such as wood, bamboo, and hemp, while modern ships primarily use steel, aluminum, fiberglass, acrylic, and various composite materials. After production, ship components require assembly.

[0003] The stern shaft is an important component of the ship's propulsion system. There are several ways to install the propeller on the stern shaft. One way is to connect the propeller directly to the stern shaft, and another way is to connect the stern shaft and the propeller through a coupling. Therefore, the fit and assembly quality of the coupling and the stern shaft are of paramount importance.

[0004] In existing sliding rail type propeller coupling devices, due to the large size and weight of the stern shaft, manual operation of the clamps for fixing can easily cause the stern shaft to shift or wobble during the fixing process, resulting in the mating surfaces between the propeller and the stern shaft not achieving a good contact state. Utility Model Content

[0005] In order to overcome the above-mentioned defects in the prior art, this utility model provides a ship accessory installation alignment and positioning device.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a ship accessory installation alignment and positioning device, including a first support frame, a stern shaft clamping mechanism provided at the upper end of the first support frame, a second support frame provided on the ground to the right of the first support frame, a third V-shaped groove block fixedly installed on the second support frame, a second gantry fixedly installed on the ground to the right of the second support frame, a sliding groove provided at the upper end of the second gantry, a first slider slidably installed left and right inside the sliding groove, a second hydraulic cylinder fixedly installed at the front of the upper end of the first slider, an installation plate fixedly installed at the telescopic end of the second hydraulic cylinder, and a propeller clamping mechanism provided at the lower end of the installation plate.

A connecting plate is fixedly mounted at the lower end of each set of the second sliders, and a clamping block is fixedly mounted on the inner side of each of the two sets of connecting plates.

[0010] Furthermore, a set of mating blocks is fixedly installed on the front and rear sides of the lower end of the mounting plate, and a second motor is fixedly installed at the rear end of the mating block on the rear side. A bidirectional lead screw is fixedly connected to the power output shaft of the second motor, and a set of second sliders is mated and installed at the threaded ends of the bidirectional lead screw.

[0011] The beneficial effects of this utility model are as follows: by activating the second hydraulic cylinder to move the propeller clamping mechanism downward, and then by driving the bidirectional screw to rotate via the second motor, the position between the two sets of clamping blocks is adjusted so that the two sets of clamping blocks can clamp the propeller and place the stern shaft inside the first V-groove and the third V-groove. Then, the first hydraulic cylinder is activated to press down the second V-groove, and the stern shaft is clamped and secured with the cooperation of the second V-groove and the first V-groove. After that, the first motor is activated to drive the screw to rotate, adjusting the left and right position of the propeller and assembling the propeller with the stern shaft. The position of the propeller is adjusted according to the installation situation, making the overall assembly process more stable and convenient. Attached Figure Description
