Description

Technical Field

[0001] This utility model belongs to the field of precision sheet metal assembly technology, specifically relating to a precision sheet metal part with a precise positioning structure. Background Technology

[0002] Precision sheet metal parts are an indispensable and important component in the manufacturing industry. They are usually made from thin sheet metal materials through precision stamping, cutting, bending and welding processes. These sheet metal parts are characterized by compact structure, high strength, light weight and beautiful appearance, and are widely used in various enclosure structures of electronic equipment, communication equipment, and mechanical equipment.

[0003] When assembling precision sheet metal parts for a box, snap-fit ​​blocks and snap-fit ​​holes are installed on the precision sheet metal parts. The snap-fit ​​structure facilitates precise positioning of the precision sheet metal parts, which are then fixed with bolts or welding. When assembling the opening and closing door of the precision sheet metal parts for the box, L-shaped rods are symmetrically fixed to the opening and closing door by bolts or welding. The L-shaped rods pass through the upper and lower surfaces of the opening and closing door, and are positioned and rotatedly connected to the main body of the precision sheet metal parts for the box. After long-term use, when the L-shaped rods wear out, it is inconvenient to quickly disassemble and maintain them, which reduces the maintenance efficiency of the opening and closing door. To address the above problems, a new precision sheet metal part with a precise positioning structure is proposed. Utility Model Content
