Description

Technical Field

[0001] The present invention relates to the technical field of large cylinder hole opening, and particularly to a cutting device. Background Art

[0002] During the layout and installation of pipeline systems in the ship and ocean engineering fields, in order to better manage space and effectively prevent interference between pipelines and cables of different systems inside the interference space, there will inevitably be oblique pipelines. Due to the existence of oblique pipes, an elliptical cross-section will be generated when the oblique pipes pass through the decks and bulkheads of the ship. Therefore, it is often necessary to open elliptical holes on the decks and bulkheads during the hull manufacturing process to facilitate the placement and welding of pipelines.

[0003] The traditional method for opening elliptical holes is to draw a standard circle on the deck with tools such as a compass according to the outer diameter of the through-hull fitting of the oblique pipe, and punch center punches; then gradually carry out gas cutting operations on the basis of this circle to continuously expand the opening area to form a relatively rough and non-standard elliptical hole, and then grind and repair the non-standard elliptical hole.

[0004] Existing elliptical hole openings are all carried out manually, which requires a large amount of labor costs. At the same time, large errors are easily caused by human factors during the hole opening process, resulting in rework or even scrapping of the entire opening area, thereby affecting subsequent welding work and even the construction quality and construction efficiency of the entire ship.

[0035] In this embodiment, the attitude adjustment mechanism 16 is fixed by the magnetic adsorption fixed universal adjustment floor bolt 17, and the magnetic adsorption fixed universal adjustment floor bolt 17 has a universal adjustment function, so that the attitude adjustment mechanism 16 can be tilted at will to avoid damage to the attitude adjustment mechanism 16 due to stress. The range adjustment mechanism 18 is connected to the mounting plate, and here the mounting plate can be the first mounting plate 9 or the second mounting plate 13; the range adjustment mechanism 18 drives the attitude adjustment mechanism 16 to move horizontally, and the attitude adjustment mechanism 16 drives the range adjustment mechanism 18 to move up and down.

Soft magnetic materials are easily magnetized under a weak magnetic field and are also easily demagnetized. By rotating the external handle, the internal magnet can be driven to rotate. When the two poles of the magnet are facing the soft magnetic material base, the base will be magnetized and exhibit strong magnetism, so that it can adsorb the steel surface; when the two poles of the magnet are in the horizontal position, the base has almost no magnetism, and the adsorbed object can be easily removed. At the same time, the magnetic adsorption fixed universal adjustment floor foot 17 has a universal arm and can be fixed at any angle, which is convenient and fast to use. Its magnetic base has a large suction force, usually up to 2-100 kg or even higher. In addition, the dial gauge clamping part is provided with a fine adjustment device, and the direction can be arbitrarily adjusted for positioning.

When adjusting the attitude adjustment mechanism 16, first loosen the hand-tightening nut, and then rotate the adjustment knob 23 on the adjustment guide sleeve 22 to realize the lifting of the adjustment guide sleeve 22, that is, the lifting of the attitude adjustment mechanism 16. And due to the existence of the rotating pair, the attitude adjustment mechanism 16 will also generate a displacement along the direction of the sliding sleeve 19 and the slide rod 20, avoiding stress damage to the range adjustment mechanism 18 and the attitude adjustment mechanism 16, and at the same time ensuring the stability of the overall connection.
