Description

Technical Field

[0001] The utility model relates to the technical field of drill rod processing, in particular to a wear-resistant composite sheet welding tool for a mining drill. Background Art

[0002] After the drill rod is processed, a drill bit needs to be connected to the head end to form a complete set of drilling equipment. Based on the need for wear resistance, the conventional models of drill bits in the current daily production of the applicant are diamond composite sheet drill bits with wear-resistant composite sheets, and the publication number is CN204899783U. The wear resistance of this type of drill bit has been greatly improved, and it is currently the mainstream drill bit used in coal mine production. In production practice, the diamond composite sheet is installed on the pre-milling part of the drill bit, that is, the assembly groove of the wear-resistant composite sheet, and then the wear-resistant composite sheet is loaded into the assembly groove, and finally welded. Due to the small size of the drill bit and the smaller size of the wear-resistant composite sheet, the welding operation at this place is generally performed manually. The problem existing in the current production is that when welding the wear-resistant composite sheet on the drill bit, it is necessary to use a bench vise to clamp the drill bit, and then weld, and when the next welding is needed, the bench vise is loosened, the clamping position of the drill bit is adjusted, and then welding is performed. Each drill bit welding requires loosening the bench vise several times to adjust the drill bit position, which is very cumbersome and has very low production efficiency. Utility Model Content

[0003] In order to solve the above problems, the purpose of the utility model is to propose a welding tool for wear-resistant composite sheets of mining drill bits. After the drill bit is clamped by a chuck, it can be rotated and adjusted at multiple angles. The welding position on the drill bit can be adjusted by rotating the tool during the entire process of welding the wear-resistant composite sheet, which effectively solves the cumbersome and inconvenient problems of traditional welding and improves production efficiency.
