The structure and corresponding matching structure of car gage part have a significant impact to complete vehicle quality, and component structural design is not
Rationally it will lead to Automobile Enterprises when producing automobile product, difficult to install, operator complains, the problems such as productive temp is slow influences
Production capacity is to influence selling market；The problem is equally equally existed when after market repairs.
Summary of the invention
The utility model is suitable for due to manufacturing tolerance, and the reasons such as operator's Rig up error cause screw thread stripped thread accident, lead
It causes mounting bracket to scrap, unnecessary cost is caused to waste, cooperate assembly connection for existing car gage part bolt and nut etc.
When the transfer phenomenon that occurs carry out the design of standard component and connected structure (mounting bracket), to achieve the above object, this is practical
New technique scheme is as follows: the connection structure of a kind of formula self-retaining nut and mounting bracket, which is characterized in that including from solid
Determine nut, connection bolt, self-retaining structure, be connected part, wherein self-retaining structure and connected part pass through connection bolt
Self-retaining nut is installed in connection, connection bolt one end；
The self-retaining structure upper is provided with self-retaining mounting bracket, and lower part is provided with installation guide rail；
The self-retaining nut two sides are respectively arranged with axial rotate position limiting structure and the position limiting structure that slides axially, axial
The position limiting structure that rotates is the flat surface structure of flange side, and the position limiting structure that slides axially is the flat surface knot of flange face cambered surface
Structure, wherein the position limiting structure that slides axially setting is on the position limiting structure that axially rotates.
The connection diameter of bolt is 28mm.
The axial direction rotates position limiting structure length as 13mm, width 25mm.
The position limiting structure width that slides axially is 16mm.
Self-retaining nut is axially rotated the alignment of position limiting structure boundary line direction from admittedly according to design by the utility model
The guide rail direction insertion card slot of fixed rack is installed to appropriate location；The position limiting structure that axially rotates can limit turn axial around nut
It is dynamic, transfer is not generated when urgent；The axial float when position limiting structure that slides axially can prevent urgent.
According to demand, material is based on structure and all passes through finite element analysis Strength co-mputation involved components.
The utility model has the following beneficial effects: the connection of a kind of formula self-retaining nut of the utility model and mounting bracket
Structure, this nut are based on common nut structure form at present and carry out practicability optimization, will change, adopt in nut flange structure
Cutting is machined after being molded with a mold or forming, its flange face unilateral (bilateral) is made planar structure occur, it can be around standard
Part is limited around axial freedom degree, to save operator and the use of other tool.Flange face cambered surface is carried out simultaneously similar
Molding or machine add processing, form flat surface, change freedom degree convenient for limitation standard component during installation axial, save behaviour
Author and other tool use, and keep positioning more convenient.The design of the utility model and corresponding matching structure design effectively solve
Vehicle height of center of mass measures difficult problem.This standard component design and corresponding matching structure design reduce assembly cost, mention
High testing efficiency.The design of the utility model increases the service life for being connected components, reduces cost.
The utility model is primarily to meet the operator's hand or used work that vehicle occurs in assembling process
Has the installation region that can not be touched；Can substantially reduce with this structure mounting bracket rate, cost advantage is obvious；This
Utility model is suitable for the production line station that productive temp needs to improve, and traditional is fixed spiral shell with a hand-held spanner on one side
Mother, another hold the urgent mounting means of clamping tool and overturn, it is only necessary to which a handheld tool is urgent, has saved work
Tool, reduces costs, has saved the time, improve work pace.
