Abstract
The utility model relates to an axial positioning pin, consisting of a pin shaft, an elastic ring, a spring and a steel ball. Two opening ends of the elastic ring are respectively installed in the two holes on one end of the pin shaft, and the spring and the steel ball are installed in a blind hole on the other end of the pin shaft. The steel ball is positioned on the upper part of the spring, then the aperture of the blind hole is riveted to be small, when makes the steel ball only be able to move inward the blind hole without falling off. When the utility model is installed, firstly the elastic ring on one end of the pin shaft is made to be broken away with the pin shaft, and the other end of the pin shaft is inserted in a radial direction hole at the end of the axle. Limited by the diameter of the radial direction hole, the steel ball is pressed into the blind hole of the pin shaft, and the spring is compressed. When the position of the steel ball penetrates the radial direction hole of the axle, under the return action of the spring, the steel ball is flipped, and the steel ball is pressed to lean against the shaft by loosening the elastic ring, in this way the two ends can be limited. The utility model prevents the positioning pin from automatic defluvium and reliable positioning, when the positioning pin is removed, the elastic ring is only needed to be drawn to make the pin shaft pulled out, the utility model is of very convenient disassembly and installation and the axial positioning pin can be used for many times.
Description
Technical field
The utility model relates to the locating stud that is used for axially locating when a kind of class installed, the axially locating pin when being adapted to axle by frequent dismounting especially.
Background technique
At present, when installation shaft, its axially locating mode generally is that axle one end is processed with the shaft shoulder, and the other end radially is processed with positioning pin hole, uses the cotter pin axially locating, opening is cut broken into two with one's hands then, prevents to come off.But when running into frequent dismounting axle, cotter pin will often be broken off with the fingers and thumb bad, and dismounting is very inconvenient, and influence is normally used.
Summary of the invention
The purpose of this utility model provides a kind of easy accessibility, locatees reliable novel axial locating stud.
The purpose of this utility model is achieved in that this locating stud is made up of bearing pin, elastic ring, spring, steel ball, elastic ring two opening ends are installed in respectively in two holes of bearing pin one end, spring and steel ball are housed in the blind hole of the bearing pin the other end, steel ball is placed on above the spring, then that the riveting of blind hole aperture is little, steel ball can only be moved in blind hole, and can not come off.
Two holes of described bearing pin one end are not on same axis, and dislocation up and down.
Described elastic ring is a trip ring, shape in the shape of a spiral after the installation.
The utility model is simple in structure, and dismounting is very convenient, and the location is reliable, and can repeatedly use.
Be described further below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is an example structure sketch of the present utility model.
Fig. 2 is the diagrammatic top view of Fig. 1.
Fig. 3 is an installation sketch of the present utility model.
Embodiment
Embodiment: this locating stud is made up of bearing pin (3), elastic ring (4), spring (1), steel ball (2), elastic ring (4) two opening ends are installed in respectively in two holes of bearing pin (3) one ends, spring (1) and steel ball (2) are housed in the blind hole of bearing pin (3) the other end, steel ball (2) is placed on above the spring (1), then that the riveting of blind hole mouth is little, steel ball (2) can only be moved in blind hole, and can not come off, two holes of bearing pin (3) one ends are not on same axis, and dislocation up and down, elastic ring (4) is a trip ring, shape in the shape of a spiral after the installation.When being installed on the axle (5), at first the elastic ring (4) of bearing pin 3 one ends and bearing pin (3) are broken off with the fingers and thumb from, bearing pin (3) the other end is inserted axle (5) end radial hole, be subjected to the restriction of radial hole diameter, steel ball (2) is pressed in bearing pin (3) blind hole, spring (1) is compressed, after steel ball (2) position passes axle (5) end radial hole, under the effect of spring (1) return, steel ball (2) is upspring, unclamp elastic ring (4) and with its be pressed against the axle (5) on, but two ends are spacing like this, prevent that locating stud from coming off voluntarily, the location is reliable; When pulling down locating stud, only need pulling elastic ring (4) that bearing pin (3) is pulled out and get final product.Dismounting is very convenient.
Claims (3)
1. novel axial locating stud, form by bearing pin, elastic ring, spring, steel ball, it is characterized in that: elastic ring two opening ends are installed in respectively in two holes of bearing pin one end, spring and steel ball are housed in the blind hole of the bearing pin the other end, steel ball is placed on above the spring, then that the riveting of blind hole aperture is little, steel ball can only be moved in blind hole, and can not come off.
2. novel axial locating stud according to claim 1 is characterized in that: two holes of bearing pin one end are not on same axis, and dislocation up and down.
