Abstract
The utility model discloses an elasticity compact form locating pin that rises. It includes shank, dabber, steel ball and spring, follows the axial and be equipped with the interstitial hole on the shank, follows the circumferencial direction and be equipped with the tieholen that rises on the shank, lies in shank outer wall department and be equipped with the fender shoulder on the tieholen that rises, and the dabber matches with the interstitial hole and is connected, and the inboard was takeed on to the fender during the tieholen that rises was located to the steel ball, and the spring is located between dabber and the steel ball. The utility model has the characteristics of rational in infrastructure, location is connected reliable, simple to operate and is practiced thrift cost etc.
Description
Technical field
The utility model relates to a kind of locating stud, especially relevant with swelled locating stud.
Background technique
As a kind of mechanical fastener, locating stud plays a part to be fixedly connected with two component, but because machinery is in running, due to the reason such as stressed, vibration, displacement, easily cause Cylindrical locating pins to loosen, even come off, cause machinery to break down, not only reduce manufacturing efficiency, and may production accident be caused.
Summary of the invention
The purpose of this utility model be to provide a kind of rational in infrastructure, be located by connecting elastic expanding compact form locating stud that is reliable, easy for installation, cost-saving, that can prevent machinery from breaking down.
For achieving the above object, the utility model is achieved through the following technical solutions.Elastic expanding compact form locating stud, comprise shank, mandrel, steel ball and spring, shank is provided with intermediate hole vertically, shank is along the circumferential direction provided with tensioner hole, tensioner hole is positioned at shank outer wall place and is provided with shoulder block, mandrel and intermediate hole in mating connection, steel ball is located in tensioner hole inside shoulder block, and spring is located between mandrel and steel ball.
Described elastic expanding compact form locating stud, its tensioner hole is provided with 1-16 along each circumferencial direction, is axially arranged with 1-36 along each, and along the circumferential direction with is axially uniformly distributed.
Described elastic expanding compact form locating stud, its mandrel adopts engineering plastics.
The utility model compared with prior art has the following advantages: (one) arranges spring and steel ball owing to adopting on tensioner hole, steel ball presses closer on the junction surface of connected element under the promotion of spring, make locating stud on the basis by location, own cylindrical face, junction surface positive pressure is increased again by steel ball, substantially increase frictional force, thus ensure that the connection reliability of pin, avoid the generation due to the unreliable mechanical equipment fault caused of pin connection; (2) be owing to adopting steel ball, spring structure, loading when locating stud is installed more convenient; (3) be because mandrel adopts engineering plastics, not only can alleviate the overall weight of locating stud, save material, reduce costs, and the mounting process of steel ball, spring can be optimized.
