Description

Technical Field

[0001] The utility model relates to the technical field of ship hull processing equipment, in particular to ship hull steel plate grinding equipment. Background Art

[0002] The hull is mainly formed by steel plates spliced ​​together. During assembly, the hull is spliced ​​together by multiple steel plates, and the joints of the steel plates are welded together to form a complete hull. After welding, the welds on the steel plates also need to be polished to maintain the flatness of the steel plates after welding, so that the hull is convenient for later construction.

[0003] The hull steel plate grinding equipment in the prior art is unable to perform height positioning of the welds that need to be ground. When grinding the welds, workers may over-grind if they are not careful, and grind the hull steel plates together, causing the hull steel plates to become uneven and lose their flatness. To this end, we provide a hull steel plate grinding equipment to solve the above problems. Utility Model Content

[0028] Working principle: When using the hull steel plate grinding equipment, first place the hull steel plate grinding equipment on the weld, and then rotate the forward and reverse screws 8. After the forward and reverse screws 8 rotate, the slider 7 can be driven to slide in the slide seat 6 to change the position of the slider 7. After the slider 7 changes its position, it drives the swing arm 9 to change its angle. After the swing arm 9 changes its angle, the contact distance between the grinding wheel 4 and the weld can be adjusted. After the contact distance between the grinding wheel 4 and the weld is adjusted, the motor 501 is started to drive the pulley 1 502 to rotate.
