用いて固定できるものに関する。The present invention relates to a vending machine for soft drinks, for example, which is attached to the lower end of a relatively heavy device, and a leg bolt or the like can be screwed there. The present invention relates to a nut that can be fixed to a metal plate for equipment by using a press machine.

A method of fixing the nut to a metal plate is known. The nut is formed in a stepped shape in which one end in the axial direction is reduced, and the edge of the hole of the metal plate is seated on the step.

定用ナットを提供することを課題とする。A press-fit type nut which is press-fitted into a metal plate and integrated therewith has a relatively weak holding force and cannot be used as a strong fixing tool. Therefore, a nut fixed to a place requiring strength is usually fixed by welding. However, when fixed by welding, welding spatter may be attached to the threaded portion of the nut, and the bolt cannot be screwed there. Further, there is a disadvantage that welding itself is troublesome. Accordingly, an object of the present invention is to provide a press fixing nut having high strength that can be integrally fixed to a metal plate using a press machine.

Is protruded thickly. The thickness in this example is substantially equal to the thickness of the nut body 2. Further, avoiding the portion to be plastically deformed, a plurality of anti-rotation ridges 5 which are spaced apart from each other in the circumferential direction and are parallel to the axial direction are formed integrally on the outer periphery of the nut body 2. The protruding height of the front end portion of the protruding ridge portion 5 is low, and the height of the rear end portion is high. However, the protrusion amount of the protruding ridge portion 5 is extremely small in any part as compared with the protrusion amount of the flange portion 4 in the radial direction.

The hole 15 of the metal plate 6 is aligned with the concave portion 16 of the twelve, the press fixing nut is arranged at the edge of the hole, and the nut body 2 is pressed into the edge of the hole 15 by the press machine 11. Then
As shown in FIG. 5, the metal plate 6 has a cylindrical portion 9 having an outer periphery of a hole edge portion which expands to include the protruding portion 5 and substantially along the outer periphery of the nut body 2.
Is transformed into Then, as shown in FIG. 3, the metal plate 6 is deformed along the outer periphery of the ridge portion 5 when the cylindrical portion 9 is formed,
As a result, it is plastically deformed so that it cannot rotate around the axis. The cylindrical portion 9 is deformed along the circumferential surface of the protruding ridge portion 5 and the protruding ridge portion 5, and protrudes more radially outward in the protruding ridge portion 5 than in other portions. At the same time, the plastically deformed portion 3 is guided by the bottom peripheral edge of the concave portion 16 and plastically deforms radially outward to form a plastically deformed portion 8. Then, the plastically deformed portion 8 and the tip of the cylindrical portion 9 come into contact with each other.

When the hole edge is machined into a cylindrical shape
The plastically deformed portion 3 is easily plastically deformed radially outward,
The metal plate 6 and the main nut can be integrally fixed in the axial direction. At the same time, the present nut and the metal plate 6 can be integrally fixed in the rotation direction by the presence of the anti-rotation ridges 5 formed integrally with the outer periphery of the nut main body 2 in the axial direction. Further, a flange portion 4 is integrally formed on the outer periphery of the rear end portion of the nut body 2 and is formed sufficiently large and thick outside the radial direction of the nut body 2. A buckling resistance near the edge is improved, and a high-strength and highly reliable press fixing nut can be provided.
