The technological scheme of the utility model is following: the steel ball locating stud; It is characterized in that, comprise locating column, the upper end of locating column is provided with the screw with the locating column spigot shaft coaxle; Be with the retainer of annular in the outer, upper end of locating column; Between the upper end portion of retainer and locating column, form circular groove, be provided with cover plate in the retainer upper end, said cover plate and locating column are together when mounted by the bolt location that is connected in the screw; On the side of retainer, also be provided with several ball holes, said ball hole is corresponding one by one with the steel ball of being located in the circular groove, and an end of steel ball all is attached on the locating column, and the other end of steel ball stretches out in the ball hole of correspondence and be spacing by this ball hole; In locating column, be provided with gas-entered passageway, form suction port in the bottom of locating column, be connected with at the suction port place and be used for the quick release coupling that is connected with gas transmission equipment; Also be provided with some ventilation branch roads on the top of locating column, described ventilation branch road is corresponding one by one with steel ball, and the inner of ventilation branch road all is communicated with gas-entered passageway, and the outer end of ventilation branch road is communicated with the circular groove of corresponding steel ball position respectively.
The locating stud of the utility model is when using installation; Utilize the rolling friction of steel ball to substitute the sliding friction of traditional locating stud; Not only can reduce the frictional force between locating stud and the mounting hole inwall, and use express delivery more convenient, save a large amount of installing and locating time.
Further again, also be provided with a positioning disk at the middle part of locating column, on this positioning disk, be provided with the assist location hole.Can increase locating point through the assist location hole, realize the multiple spot co, help the stability after the enhanced positioning pin is installed.
Further again, said ball hole is ten and on retainer, evenly distributes.Equally distributed ball helps keeping the balance of locating stud, all can play the effect of rolling friction from all angles, the big resistance of avoiding sliding friction to bring.
With respect to existing technology, the utlity model has following beneficial effect:
The steel ball locating pin structure of the utility model is simple, adopts the structural type of rolling bearing, can install more efficiently, and reduce the friction of locating stud and hole wall, locatees more accurate.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As depicted in figs. 1 and 2, the steel ball locating stud of the utility model comprises locating column 1, and the upper end of locating column 1 is provided with the screw 2 with the locating column spigot shaft coaxle, this screw 2 be used for cylinder body mounting hole to be processed in bolt be connected.Be with the retainer 3 of annular in the outer, upper end of locating column 1; Between the upper end portion of retainer 3 and locating column 1, form circular groove 4; Cover plate 5 covers the top of locating column 1 and retainer 3 and said circular groove 4 is sealed; The center hole of said cover plate 5 and screw 2 couplings, the effect of cover plate 5 here is retainer 3 fixed limits.During installation, cover plate 5 is connected fixing with locating column 1 by bolt.On the side of retainer 3, also be provided with several ball holes 6, the ball hole 6 in the utility model is ten and on retainer 3, evenly distributes, certainly, also can set flexibly as required.Said ball hole 6 is corresponding one by one with steel ball 7 in being located at circular groove 4; And steel ball 7 all is unified sizes with ball hole 6 separately; One end of steel ball 7 all is attached on the locating column 1, and the diameter of steel ball 7 is greater than the aperture of ball hole 6, so the outer end branch of steel ball 7 stretches out from each self-corresponding ball hole 6; But steel ball 7 is still spacing by this ball hole; Like this, each steel ball 7 just can only freely roll in the position of ball hole 6 and can contact with the installation hole wall of outside, but can not break away from the scope of ball hole.
Referring to Fig. 1, in locating column 1, also be provided with gas-entered passageway 8, this gas-entered passageway 8 forms suction port 9 in the bottom of locating column 1, be connected with at suction port 9 places to be used for the quick release coupling 10 that is connected with gas transmission equipment.Also be provided with some ventilation branch roads 11 on the top of locating column 1, described ventilation branch road 11 is corresponding one by one with steel ball 7, and the inner of ventilation branch road 11 all is communicated with gas-entered passageway 8, and the outer end of ventilation branch road 11 is communicated with the circular groove 4 of corresponding steel ball position respectively.The purpose that gas-entered passageway 8 and ventilation branch road 11 are set in the utility model is, can with the removings such as dust, sandy soil and bar that remain in steel ball surface or the circular groove 4, ensure that steel ball can rotate flexibly through the stronger air pressure of outside input.
Referring to Fig. 1, also be provided with a positioning disk 12 at the middle part of locating column 1, on this positioning disk 12, be provided with assist location hole 13.The effect in assist location hole 13 is to increase the mounting points of locating stud, and is more stable after it is installed, and do not produce and rocks.
Working principle: during installation; With the screw of locating column 1 upper end 2 directly with mounting hole in bolt be connected and get final product; In the process of locating column 1 being put into mounting hole, contact through steel ball between the inwall in locating column 1 and hole, because steel ball can freely roll; Therefore reduced greatly and the mounting hole inwall between friction, can realize the express delivery location.Then as required, can select assist location hole 13 also is fixedly connected, increase the stability of locating stud with this.When dirt occurring in the circular groove 4 or on the steel ball, gas transmission equipment is connected on the quick release coupling 10, inflate in locating stud through gas-entered passageway 8, utilize gas pressure power that the dirt in steel ball or the circular groove is cleaned out, make the steel ball can normal rotation.
The steel ball locating stud of the utility model is in assembly process, and the size of steel ball and the size of locating column all have higher requirement, need come the accurately dimensional accuracy of configuration locating stud according to the mounting hole size of measuring.
