a one-piece nut

技术领域 technical field

本实用新型涉及机械制造领域，具体地说，是一种将垫圈与螺母做成一体的一体式螺母。 The utility model relates to the field of mechanical manufacturing, in particular to an integrated nut in which a washer and a nut are integrated.

背景技术 Background technique

螺母是机械制造行业用的非常多的零件之一，而且，它基本是与垫圈共同使用的。目前，螺母与垫圈通常是分开的，各为独立的零件，这样，在安装使用时需要分别使用，在安装工作量非常大时，需要使用许多螺母和垫圈，一个个装配、安装还是比较麻烦的。而将垫圈与螺母做成一体式的螺母，这在目前似乎还没有见到。 The nut is one of the many parts used in the machinery manufacturing industry, and it is basically used together with the washer. At present, nuts and washers are usually separated, and each is an independent part. In this way, they need to be used separately during installation and use. When the installation workload is very large, many nuts and washers need to be used, and it is troublesome to assemble and install one by one. . And the washer and nut are made into an integrated nut, which seems to have not been seen at present.

实用新型内容 Utility model content

本实用新型旨在解决上述问题，提供一种将垫圈与螺母做成一体的一体式螺母，方便安装——在拧紧过程中依靠螺母与垫圈之间的相对转动起到垫圈的作用；并且可以在有效连接长度不变的情况下使螺母的长度变短，节约材料。 The utility model aims to solve the above problems, and provides an integrated nut with the washer and the nut integrated, which is convenient for installation—the relative rotation between the nut and the washer plays the role of the washer during the tightening process; When the effective connection length remains the same, the length of the nut is shortened to save material.

为实现上述目的，本实用新型采取的技术方案如下。 In order to achieve the above object, the technical scheme that the utility model takes is as follows.

一种一体式螺母，含有螺母体，其特征是，在所述螺母体的下端设置一个台阶，所述台阶通过配合设置一个垫圈结构，所述台阶的深度与所述垫圈结构的厚度相一致，使所述垫圈结构与所述螺母体成为一体。 An integrated nut, which contains a nut body, is characterized in that a step is arranged at the lower end of the nut body, and a washer structure is arranged on the step through cooperation, and the depth of the step is consistent with the thickness of the washer structure, The washer structure is integral with the nut body.

进一步，所述配合为过盈配合：通过所述台阶的外径与所述垫圈结构的内孔之间的配合，通过压力将垫圈结构安装在螺母体的外径上。 Further, the fit is an interference fit: through the fit between the outer diameter of the step and the inner hole of the washer structure, the washer structure is installed on the outer diameter of the nut body by pressure.

进一步，所述配合为间隙配合：将垫圈结构装上台阶后在螺母体与垫圈结构的共同侧面加上一个力，依靠侧面的变形使垫圈结构牢固地安装在螺母体上。 Further, the fit is clearance fit: after the washer structure is installed on the steps, a force is applied to the common side of the nut body and the washer structure, and the washer structure is firmly installed on the nut body by the deformation of the side.

本实用新型一种一体式螺母的积极效果是： The positive effect of a kind of integrated nut of the utility model is:

（1）垫圈结构通过台阶直接设置在螺母体上，使垫圈结构与螺母体成为一体化结构，便于机械制造行业安装使用，节省安装时间。 (1) The washer structure is directly arranged on the nut body through steps, so that the washer structure and the nut body become an integrated structure, which is convenient for installation and use in the machinery manufacturing industry and saves installation time.

（2）在有效连接长度不变的情况能缩短传统螺母与垫圈安装后的实际长度，节省材料。 (2) When the effective connection length remains unchanged, the actual length of the traditional nut and washer after installation can be shortened, saving materials.

（3）提高了垫圈与螺母之间安装的径向精度。 (3) The radial accuracy of the installation between the washer and the nut is improved.

具体实施方式 Detailed ways

以下结合附图介绍本实用新型一种一体式螺母的具体实施方式。但是需要指出，本实用新型的实施不限于以下的实施方案。 The specific implementation of an integrated nut of the present invention will be introduced below in conjunction with the accompanying drawings. However, it should be pointed out that the implementation of the present invention is not limited to the following embodiments.

参见附图1。一种一体式螺母，含有六面体的螺母体1（可为传统的螺母结构），在所述螺母体1的下端设置一个台阶2，所述台阶通过过盈配合或者间隙配合设置垫圈结构3，所述台阶2的深度与所述垫圈3的厚度相一致。所述过盈配合为：通过所述台阶2的外径与所述垫圈结构3的内孔之间的配合，通过压力将垫圈结构3安装在螺母体1的外径上；所述间隙配合为：将垫圈结构3装上台阶2后在螺母体1与垫圈结构3的共同侧面加上一个力，依靠侧面的变形使垫圈结构3牢固地安装在螺母体1上，使所述垫圈结构3与所述螺母体1成为一体。 See attached drawing 1. An integrated nut, which contains a hexahedral nut body 1 (which can be a traditional nut structure), and a step 2 is set at the lower end of the nut body 1, and the step is provided with a washer structure 3 through interference fit or clearance fit, so The depth of the step 2 is consistent with the thickness of the washer 3 . The interference fit is: through the cooperation between the outer diameter of the step 2 and the inner hole of the washer structure 3, the washer structure 3 is installed on the outer diameter of the nut body 1 by pressure; the clearance fit is : After the washer structure 3 is installed on the step 2, a force is added to the common side of the nut body 1 and the washer structure 3, and the washer structure 3 is firmly installed on the nut body 1 by the deformation of the side, so that the washer structure 3 and the washer structure The nut body 1 is integrated.

安装使用时，螺母体1通过垫圈结构3与连接件拧接，避免了安装时分别使用螺母和垫圈的麻烦，既方便了安装——在拧紧过程中依靠螺母体1与垫圈结构3之间的相对转动起到垫圈的作用；又可以在有效连接长度不变的情况下使螺母的长度变短，节约材料。 During installation and use, the nut body 1 is screwed to the connector through the washer structure 3, which avoids the trouble of using nuts and washers separately during installation, and facilitates installation—rely on the connection between the nut body 1 and the washer structure 3 during the tightening process The relative rotation plays the role of a washer; and the length of the nut can be shortened under the condition that the effective connection length remains unchanged, so as to save materials.
