Embodiment Construction

[0047] In order to further explain the technical solution of the present invention, it will be described in detail below in conjunction with the accompanying drawings.

[0048] refer to Figure 1 to Figure 5, a nut assembly method, the nut 70 includes a nut body and a washer 73 rotatably arranged on the nut body, the nut body includes a base 71 and an annular boss 72 arranged on the base 71, the annular boss 72 One end is the connecting end 721 connected to the base 71, and the other end is a free end 722. The nut 70 is commonly used in automobile bolts. The nut body is isolated from the surface of the fastener to be fastened by the washer 73, avoiding the nut The body scratches the fasteners to be fastened. The assembly method of this nut 70 comprises the steps:

[0049] A. Place the nut body on the workbench 11 with the annular boss 72 facing upwards, and place the washer 73 on the annular boss 72;

[0050] B. Use the indenter to press the ring-shaped boss 72, so that the...

Abstract

The invention relates to a nut assembling method. The nut assembling method includes the following steps: A, putting a nut body on a workbench, enabling a circular boss to be face upwardly, and sleeving the circular boss with a gasket; B, ejecting the circular boss by press heads to enable the free end of the circular boss to extend to press the inner wall of the gasket; C, applying acting force to the gasket or the circular boss to enable the free end of the circular boss to shrink inwardly, enabling the gasket to flexibly rotate relative to the circular boss and preventing the gasket from falling from the circular boss. By the nut assembling method, produced products do not need rework basically, and rate of finished products can be increased effectively. The invention further provides nut assembling equipment. The free end of the circular boss is ejected to the inner wall of the gasket through the first press head, and is separated from the inner wall of the gasket through the second press head. By the equipment, rework in nut assembly can be reduced greatly, and production efficiency can be improved.

Description

technical field [0001] The invention relates to a nut assembly method and assembly equipment. Background technique [0002] A nut is a very common fastening connection part, usually used in conjunction with a bolt or a screw. There is a type of nut on the market, which includes a nut body and a washer rotatably arranged on the nut body. During the tightening process of the nut, the nut body will not directly contact with the parts to be tightened, which can avoid the nut on the parts. wear and tear. For example, the authorized announcement number CN204458762 U, the Chinese invention patent titled "A New Type of Nut", discloses a new type of nut, including a body, which is a hollow cylinder with openings at both ends in the axial direction. , which also includes a cover body and a movable washer, the above-mentioned cover body is a hollow cylinder with an open shape at one axial end, the above-mentioned cover body is arranged outside the port of the first axial end of the a...
