Abstract
The invention discloses a connection piece of a machine part. The connection piece comprises a bolt and a nut. The nut comprises a nut body. The bolt comprises a threaded rod section and a nut end arranged at the end of the threaded rod section. The end face, close to the threaded rod section, of the nut end is provided with a plurality of elastic protrusions. The end face, close to the nut end, of the nut body is provided with a plurality of elastic protrusions. The elastic protrusions can elastically deform in the bolt screwing process. By means of the connection piece, the good looseness prevention capacity is still achieved even under the condition that no elastic gaskets are used in cooperation.
Description
Technical field
The present invention relates to mechanical fastener technical field, particularly relate to a kind of mechanical component web member.
Background technology
Bolt is a kind of mechanical component, is generally the fastening piece joined with the cylinder shape belt screw thread of nut. Bolt is made up of head and screw rod (with externally threaded right cylinder) two portions, it may also be useful to time need to coordinate with nut, and for being fastenedly connected two parts with through hole, this kind of type of attachment claims bolt to connect. Under nut is revolved from bolt, can make again these two parts separately, therefore bolt connection belongs to removably connect. Divide by the force way connected: point common and have articulation hole. Divide by nose shape: have hex hd, round end, square head, heavy head etc. Wherein hex hd is the most frequently used.
At present, for bolt connect locking, comparatively general a kind of form be adopt elastic washer. But in the maintenance process or assembling process of reality; particularly in maintenance process, often can because of the carelessness or not responsible of maintenance personnel, it does not have elastic washer is sheathed on bolt; cause tie point absent-mindedness under vibrations, seal failure occurs or connects lax situation to occur.
Summary of the invention
For in above-mentioned prior art in the maintenance process of reality or assembling process; particularly in maintenance process; often can because of the carelessness or not responsible of maintenance personnel; elastic washer is not sheathed on bolt; cause tie point absent-mindedness under vibrations; seal failure occur or connect lax situation produced problem, the present invention provides a kind of mechanical component web member.
A kind of mechanical component web member provided by the invention is dealt with problems by following technical essential: a kind of mechanical component web member, comprise screw rod and nut, described nut comprises nut body, described bolt comprises spiro rod section and is arranged at the screw cap end of spiro rod section end, described screw cap end on the end face of spiro rod section, nut body on the end face of screw cap end, be provided with multiple elastic bumps, described elastic bumps can produce in the process that bolt is tightened elasticity distortion.
In this structure, the spiro rod section of setting has screw thread, for bolt connect in be threaded with nut, with fastening interconnective web member, above screw cap end as operator brake spiro rod section rotate turn parts. In this structure, by arranging elastic bumps in screw cap end on the end face of spiro rod section one end, like this, in the process that bolt is tightened, elastic bumps generation elastic deformation, the elastic force that above elastic deformation produces can be used as the prestress of screw retention, like this, this bolt, when not matching use cushion, also has good anti-loosening ability.
Arrange nut body for being connected with screw flight, with fastening interconnective connection. In this structure, by arranging elastic bumps on the end face of any one end of nut body, like this, in the process that nut is tightened, elastic bumps contacts with workpiece and elastic deformation occurs, and the elastic force that above elastic deformation produces can be used as the locking prestress of nut body, like this, this bolt, when not matching use cushion, also has good anti-loosening ability.
Further technical scheme is:
For making above prestress be uniformly distributed in the circumference of bolt, the elastic bumps on two end faces is all uniform in the form of a ring relative to the axis of spiro rod section.
As making above prestress be uniformly distributed further technical scheme in the circumference of bolt, the number of the elastic bumps on two end faces is all greater than 3.
As a kind of web member form being convenient to processing and manufacturing, the elastic bumps in described screw cap end, spiro rod section and screw cap end is the one-piece construction by having cast; Elastic bumps in described nut body and nut body is the one-piece construction by having cast.
The present invention has following useful effect:
In this structure, the spiro rod section of setting has screw thread, for bolt connect in be threaded with nut, with fastening interconnective web member, above screw cap end as operator brake spiro rod section rotate turn parts. In this structure, by arranging elastic bumps in screw cap end on the end face of spiro rod section one end, like this, in the process that bolt is tightened, elastic bumps generation elastic deformation, the elastic force that above elastic deformation produces can be used as the prestress of screw retention, like this, this bolt, when not matching use cushion, also has good anti-loosening ability.
Arrange nut body for being connected with screw flight, with fastening interconnective connection. In this structure, by arranging elastic bumps on the end face of any one end of nut body, like this, in the process that nut is tightened, elastic bumps contacts with workpiece and elastic deformation occurs, and the elastic force that above elastic deformation produces can be used as the locking prestress of nut body, like this, this bolt, when not matching use cushion, also has good anti-loosening ability.
Accompanying drawing explanation
Fig. 1 is the structural representation of an a kind of mechanical component web member specific embodiment of the present invention.
Numbering in figure is followed successively by: 1, screw cap end, and 2, spiro rod section, 3, elastic bumps, 4, nut body.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but the structure of the present invention is not limited only to following examples.
Embodiment 1:
As shown in Figure 1, a kind of mechanical component web member, comprise screw rod and nut, described nut comprises nut body 4, described bolt comprises spiro rod section and is arranged at the screw cap end 1 of spiro rod section end, described screw cap end 1 on the end face of spiro rod section, nut body 4 on the end face of screw cap end 1, be provided with multiple elastic bumps 3, described elastic bumps 3 can produce in the process that bolt is tightened elasticity distortion.
In this structure, the spiro rod section 2 of setting has screw thread, for bolt connect in be threaded with nut, with fastening interconnective web member, above screw cap end 1 as operator brake spiro rod section 2 rotate turn parts. In this structure, by arranging elastic bumps 3 on the end face of spiro rod section 2 one end in screw cap end 1, like this, in the process that bolt is tightened, there is elastic deformation in elastic bumps 3, the elastic force that above elastic deformation produces can be used as the prestress of screw retention, like this, this bolt, when not matching use cushion, also has good anti-loosening ability.
