Problems solved by technology

[0002] Generally, when threaded fasteners are used to connect mechanical parts, gaskets or washers are mostly provided between the threaded fasteners and the end faces of mechanical parts. There are elastic gaskets and anti-skid gaskets to increase the preload of threaded fasteners. Force, anti-skid ability, etc., the number and types of gaskets are used too much, which not only complicates the installation and fastening process, but also causes waste of gasket making materials

Embodiment 1

[0020] like figure 1 Shown is a structural schematic diagram of the first embodiment of the present invention, a fastening connection structure of mechanical parts, including threaded fasteners 2 connecting at least two mechanical parts 1, and threaded fasteners are provided in the mechanical parts. The installation hole 3 is provided with an anti-slip structure on the mouth end surface 31 of the installation hole. The anti-slip structure includes several grooves 4 arranged on the mouth end surface of the installation hole, and the threaded fasteners are tightly pressed on the grooves after the mechanical parts are fastened and connected. In this embodiment, the grooves are arranged in a radial direction corresponding to the installation hole and are evenly distributed on the end surface of the installation hole.

[0021] According to the actual installation situation and needs, the grooves can be provided on the upper and lower ends of the mouth of the installation hole.

Embodiment 2

[0023] like figure 2 The structure schematic diagram of the second embodiment of the present invention is shown, the anti-slip structure includes several convex strips 5 arranged on the end face of the mouth of the installation hole, and the threaded fasteners are tightly pressed on the convex strips after fastening the mechanical parts. In this embodiment, the protruding lines are arranged in a radial direction corresponding to the installation hole and are evenly distributed on the end surface of the installation hole.

[0024] According to the actual installation situation and needs, convex lines can be provided on the upper and lower ends of the mouth of the installation hole.

Embodiment 3

[0026] Changes are made on the basis of Embodiments 1 and 2, such as image 3 The structural diagram of the third embodiment of the present invention is shown, a groove 4 is provided on the mouth end surface at one end of the installation hole, and a convex strip 5 is provided on the mouth end surface at the other end of the installation hole.

[0027] In all the above-mentioned embodiments, the threaded fasteners are bolts and nuts. Of course, internal threads can also be set in the mounting holes, and then bolts or screws can be used to thread the mounting holes for fastening, or double-ended studs and nuts can be used to realize mechanical fastening. Fast connections between parts. In the actual fastening connection, there may be higher requirements for preload between mechanical parts, so if image 3 As shown, an elastic washer is added. It is very convenient to adopt the structure of the present invention to realize the process of assembling and fastening connection wit...

Abstract

The invention discloses a fastening connection structure for mechanical parts. The fastening connection structure comprises a thread fastening piece connected with at least two mechanical parts; an installation hole through which the thread fastening piece passes is formed in each mechanical part; and an anti-slip structure is arranged on the end surface of an opening of the installation hole. The fastening connection structure is extremely simple and convenient to manufacture, the using quantity and the types of gaskets or gasket rings are reduced and the thread fastening piece and the mechanical parts are prevented from sliding mutually.

Description

technical field [0001] The invention relates to a fastening connection structure of mechanical parts. Background technique [0002] Generally, when threaded fasteners are used to connect mechanical parts, gaskets or washers are mostly provided between the threaded fasteners and the end faces of mechanical parts. There are elastic gaskets and anti-skid gaskets to increase the preload of threaded fasteners. Force, anti-skid ability, etc., the number and types of gaskets are used too much, which not only complicates the installation and fastening process, but also causes waste of gasket manufacturing materials. Contents of the invention [0003] The problem to be solved by the present invention is to provide a fastening connection structure of mechanical parts, which is very simple in structure and convenient in manufacture, saving the number and types of gaskets or washers used. [0004] In order to solve the above technical problems, the present invention adopts the follow...
