Abstract
Provided is a bolt fastening device. A bolt hole A through which a bolt can penetrate is formed in a workpiece A. A bolt hole B through which the bolt can penetrate is formed in a workpiece B. As for the bolt hole A, a panel at a perforation part is recessed to the inner side of the workpiece A to form a horn-shaped round hole with a sealed bottom face, the bottom face of the round hole is perforated to form the bolt hole A, and the diameter of the bolt hole A is smaller than the diameter of the bottom face of the round hole. The bolt is easier to fix after being screwed in. The bolt does not protrude out of the panel of the workpiece A after being screwed into the bolt hole A, and therefore later mounting of the workpiece A is facilitated. Besides, the workpiece A and the workpiece B are not in contact with each other, so that the situation that the panel of the workpiece A and a panel of the workpiece B generate mutual friction and consequently using performance is affected is prevented. A nut corresponding to the bolt hole B is fixed to the inner side face of the workpiece B, so that the bolt is directly stretched and screwed into the nut from the outside and the problem that the tightening effect is affected by an incorrect driving angle of the nut in the driving process is solved easily.
