Description

Technical Field

[0001] The utility model relates to the field of cutting, in particular to a multi-angle adjustable assisted cutting device. Background Art

[0002] When welding two products, once leakage occurs, the welding of the products will be unsatisfactory, gaps will be generated at the welded part, and it will not meet the quality inspection requirements. For products that do not meet the requirements, rework is required, and the welded part is cut and separated using a grinding disc for cutting. When cutting and separating small products, since the cutting and separating part is not large, the grinding disc can be held by hand to complete the operation; for cutting large products, such as cutting and separating two hollow hemisphere products that form a large hollow spherical product, the welded part is a circle with the maximum diameter of the hollow spherical product. When an operator holds the grinding disc to cut and separate, they need to always maintain stability, otherwise they will cut the hollow hemisphere product, resulting in the scrapping of the entire hollow spherical product. In a utility model patent authorized and announced on December 22, 2023, with the announcement number CN 220219164 U, a multi-angle adjustable cutting device for ore is disclosed, which adjusts the placement direction of the ore by rotating the turntable, and then adjusts according to the height of the ore and the position and angle to be cut: the height of the telescopic rod, the angle between the robotic arm and the slider, and the angle between the sliding component and the slider. However, this cutting device cannot be adapted to cut the welded part of the largest circumference of the large hollow spherical product, and the adjustable angles are relatively few.
