Abstract
The utility model discloses a novel positioning pin which comprises a cylindrical pin body, and the surface of the pin body is provided with a groove along the axial direction of the pin body. Through forming the groove on the surface of the pin body along the axial direction of the pin body, in the process of pressing the positioning pin, air at the bottom of a positioning pin hole can be discharged along the groove, thereby avoiding that high-pressure air is formed at the bottom of the positioning pin hole, and ensuring that the positioning pin can be installed in place.
Description
Technical field
The utility model relates to a kind of locating stud that in vehicle assembling and manufacturing field, uses.
Background technique
In the prior art, locating stud is widely used in mechanical assembly process, and it connects each part with the mode of interference fit, prevents between each part to cause because of slide relative the fracture of connecting bolt.When being located by connecting with two locating studs two parts heavier, earlier limit of part is rested on another part surface installing and often adopt during dismounting, the one side one side of sliding is rotated progressively two parts is connected or dismounting then; Therefore the locating stud height could be installed smoothly two parts and play an important role; But press-fit in the process at locating stud, along with locating stud is pressed in the positioning pin hole, the air in the positioning pin hole can be compressed; Form high pressure; Locating stud is difficult to be press fit at the bottom of the positioning pin hole, and it is higher to cause locating stud to expose the part surface height, thereby influences the installation of part.
The model utility content
The utility model technical problem to be solved just provides a kind of locating stud of being in place of can guaranteeing.
The utility model adopts following technological scheme:
A kind of novel location pin comprises cylindrical shank, on the shank axial direction of upper edge, shank surface, offers groove.
Further, described groove cross section is a V-arrangement.
Further, described groove has 3, and they are spacedly distributed on the shank surface.
The beneficial effect of the utility model is:
(1) on the shank axial direction of upper edge, shank surface, offers groove, press-fit in the process, can discharge the air of positioning pin hole bottom along groove, avoid the positioning pin hole bottom to form high-pressure air, guarantee that locating stud can be in place at locating stud.
(2) locating stud groove cross section is a V-arrangement, and after locating stud pressed fit into positioning pin hole, V-arrangement seamed edge and locating stud hole wall formed the high pressure contact area, play anti-skidding conduct.
(3) groove has 3, and they are spacedly distributed on the shank surface, can make high-pressure air pass through 3 grooves and discharge respectively, improves exhaust efficiency and stability.
