Abstract
The utility model relates to a free positioning pin, which is composed of integration which is formed by three parts of a screw clamping head, a pin body and a pin neck, and a screw cap which is sheathed with the screw clamping head, wherein the diameter of the pin neck is larger than the diameter of the screw clamping head and is smaller than the diameter of the pin body; when the utility model is used, the screw clamping head passes through a mounting hole on a part, and the screw clamping head is sheathed with a corresponding screw cap, and then, the positioning pin can be easily arranged on the part to exert a positioning function; the utility model has the advantages of convenient installation and production efficiency enhancement; because the main function of the positioning pin is positioning, after all relevant parts are assembled, the positioning pin has no function; the positioning pin can be taken off to be used for the assembly of the next part by the disassembly of the screw cap, and thus, production cost is reduced.
Description
Technical field
The utility model relates to a kind of pin, is specifically related to a kind of automobile locating pin structure commonly used.
Background technique
The modes as shown in Figure 1 of the many employings of the pin of using always on the automobile at present, promptly it is the integral body that is made of cylindrical chuck 11 and shank 12, the 13rd, the pin neck.There is following some shortcoming and defect in its: the one, and must rely on pin dish 11 is welded on the part and just can play positioning action; The 2nd, function is less, only has use value one time.
Summary of the invention
The purpose of this utility model is at above shortcomings on the prior art, and a kind of free locating stud is provided, and it is simple, easy for installation and have dismountable function to reach the location, can repeatedly use.
The technical solution adopted in the utility model is as follows:
This free locating stud forms an integral body by screw thread dop, shank and pin neck three parts and forms with the nut that the screw thread dop is nested, wherein sell the neck diameter greater than the diameter of screw thread dop and less than the shank diameter, during use the screw thread dop passed the mounting hole on the part, put corresponding nut, just can be installed on locating stud on the part easily and play the role of positioning.Because of the main effect of locating stud is the location, after relevant all parts install, locating stud will no longer work, and can be used for the installation of part next time to the locating stud taking-up by the dismounting nut.
Therefore, this locating stud has following significant advantage:
1, locating stud no longer needs by welded and installed on part, and is easy for installation, improved manufacturing efficiency;
2, after finishing positioning action, detachably get off, reuse, reduced cost of production.
