Abstract

The utility model discloses an adjustable washer for soft metal surfaces, which belongs to the field of auto parts. The washer is in the shape of a disc with a central through hole, and its circular outer surface is stepped. The end face of the step with a larger diameter is provided with tooth-shaped embossing, and the central through hole is set on the end face of the step with a smaller diameter. Above, the central through hole is a waist-shaped hole. The utility model has the advantages of simple structure, high hardness, low cost, convenient installation and debugging, and can prevent the soft metal surface from being directly contacted by the bolt when the anti-loosening bolt is assembled, thereby preventing the soft metal surface from being damaged.

Description

Adjustable washers for soft metal surfaces

technical field

The utility model relates to the field of auto parts, in particular to an adjustable washer for soft metal surfaces, which is especially suitable for application in the installation environment where the hole position error of two parts in auto parts is relatively large and there is a requirement for anti-loosening .

Background technique

In the prior art, people often adopt the method of high torque and high speed to directly assemble the anti-loosening bolts on the vehicle parts with soft metal on the surface. The above-mentioned prior art solutions have the following defects: 1. Some soft metal parts During the process of assembling bolts, auto parts need to be rotated at high speed with high torque. If anti-loosening bolts are used directly, high temperature will be generated during high-speed assembly and the metal surface will be damaged. The bolt is closely connected with the surface of the above-mentioned soft metal, so after the anti-loosening bolt is assembled, it is difficult for the staff to adjust the position of the anti-loosening bolt.

Contents of the invention

The purpose of this utility model is to overcome the deficiencies of the background technology, and provide an adjustable washer for soft metal surface, so that when the anti-loosening bolt is assembled, the bolt can not directly contact the soft metal surface, and can prevent the soft metal The surface is damaged.

In order to achieve the above object, the technical solution of the utility model is: an adjustable washer for soft metal surface, the washer is in the shape of a disc with a central through hole, and its circular outer surface is stepped, characterized in that: in the diameter of the washer The end surface of the larger step is provided with tooth-shaped embossing, and the central through hole is arranged on the end surface of the step with a smaller diameter, and the central through hole is a waist-shaped hole.

In the above technical solution, the tooth-shaped embossing is a straight-toothed embossing.

The washer is made of 35# high-quality carbon structural steel. The utility model embosses the straight tooth type on the washer on the soft metal surface, so that the step surface of the washer is embedded in the hole of the soft metal, so that the washer can be Turn freely.

Setting the central through hole as a waist hole can make it easier for the staff to adjust the installation position of the anti-loosening bolt, eliminate the influence of part hole position error, and improve the assembly accuracy of the bolt and vehicle parts.

The utility model has the advantages of simple structure, high hardness, low cost, convenient installation and debugging, and can prevent the soft metal surface from being directly contacted by the bolt when the anti-loosening bolt is assembled, thereby preventing the soft metal surface from being damaged.

Detailed ways

The implementation of the utility model will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation of the utility model, and are only examples. At the same time, the advantages of the utility model are made clearer and easier to understand through description.

As shown in Figures 1 to 3, the soft metal 7 is installed on the bracket 6, and the washer 1 is located between the end portion of the anti-loosening bolt 8 and the soft metal 7, and the washer 1 is in the shape of a disc with a central through hole 4 , its circular outer surface is stepped, and the tooth-shaped embossing 3 is provided on the step end face 2 with a larger diameter of the gasket, and the central through hole 4 is arranged on the step end face 5 with a smaller diameter, and the central through hole 4 is waist hole. Preferably, the tooth-shaped embossing 3 is a straight-toothed embossing.

Other unspecified parts belong to the prior art.
