The invention relates to a near-water-surface cutting platform of a numerical control plasma cutting machine. The near-water-surface cutting platform of the numerical control plasma cutting machine comprises a water tank and a plurality of supporting columns, wherein the supporting columns are evenly arranged on the bottom face of the water tank; a detachable partition plate is arranged in the middle of the water tank, a step used for supporting the partition plate is arranged on the inner wall of the water tank, and a plurality of through holes for the supporting columns to conveniently pass are formed in the partition plate; the bottom faces of the supporting columns are provided with cooling grooves communicated with the interiors of the supporting columns, the water tank is provided with a plurality of connecting pieces for conveniently installing the supporting columns, one connecting piece corresponds to one supporting column, the connecting pieces and the supporting columns are fixedly connected through threads, and water passing holes used for being communicated with the cooling grooves in the supporting columns are formed in the connecting pieces. The near-water-surface cutting platform of the numerical control plasma cutting machine has the advantages that the near-water-surface cutting platform can be used for eliminating more than 90% of dust, and the using period of the cutting platform is prolonged by more than 3 times compared with the original using period. Certain water columns exist in the cooling grooves, and therefore heat dissipation of the supporting columns is facilitated.

The invention provides an underwater cutting jig frame. The underwater cutting jig frame comprises a box body, wherein a platform is mounted in the middle of the inner side of the box body; a material frame is arranged on the upper side of the platform; a group of air pipelines are arranged in the box body; an air chamber is buckled on the upper side of the box body; a bracket is arranged above the air chamber; a material frame is arranged above the bracket. According to the underwater cutting jig frame, compressed air is injected into the jig frame, so that water is raised and exceeds a to-be-cut sheet material, the to-be-cut sheet material is cut by a plasma cutting machine, and the water is saved; each part can be detached according to requirements, so that the underwater cutting jig frame is greatly convenient to clean and maintain.
