Abstract
The utility model discloses a pin positioning structure and relates to the technical field of mechanical connection. The pin positioning structure is characterized in that the structure comprises a circular sleeve (1) and a pin (4), the circular sleeve consists of a flange (2) and a sleeve body (3), and a through hole is axially arranged in the middle of the circular sleeve (1); the sleeve body (3) of the circular sleeve is arranged in the through hole of an object a (5) and the outer ring of the flange (2) of the circular sleeve is circumferentially lapped on the object a (5); and one section of the pin (4) is matched with the through hole of the circular sleeve (1) and the other section of the pin (4) is matched with the pin hole of an object b (6). Thereby, the pin holes are not required to be machined in installation fields, the construction difficulties are reduced and the operation efficiency is improved. The utility model is also suitable for the situation that the machining of the matching pin holes of two objects is difficult.
Description
Technical field
The utility model relates to the mechanical coupling technical field, specially refers to a kind of convenience is located two mounted item in the erecting bed pin structure.
Background technique
When two mounted item need be located in the engineering goods, after usually two objects being assembled together, common pin hole processing, thus the purpose of two articles is located in realization fully; But the processing of pin-and-hole is generally finished in manufactory, and for the situation that need determine two assembly parts positions in the erecting bed, the processing of pin-and-hole is often relatively more difficult, therefore is badly in need of a kind of pin structure of being satisfied with the location, erecting bed.
Summary of the invention
In order to overcome the deficiency in the background technique, the purpose of this utility model provides pin hole processing on a kind of workpiece that does not need installing and locating at the scene, and realizes the structure of workpiece by the bearing pin location.
For achieving the above object, the utility model adopts following technological scheme:
A kind of finger setting structure comprises circle cover and bearing pin, and described circle cover is made up of flange and cover body, and circle cover middle part is a through hole axially; Circle condom body is arranged in the object a through hole, and circle cover flanged outer ring circumferentially is overlapped on the object a; Bearing pin overlaps through hole with circle for one section and cooperates, and another section of bearing pin cooperates with object b pin-and-hole.
Described finger setting structure, bearing pin is interference or excessively cooperates with circle cover through hole.
Described finger setting structure, circle cover lip diameter is greater than object a through-hole diameter.
Described finger setting structure, circle condom body diameter is less than object a through-hole diameter.
Described finger setting structure, the flange of described circle cover and cover body are set to one.
Owing to adopted technique scheme, the utlity model has following beneficial effect;
Owing to set up round nested structure, during assembled in situ, only need one section of bearing pin with after the circle cover cooperates, circle is placed in the object a through hole, simultaneously another section of bearing pin is cooperated with object b pin-and-hole, circumferentially welds round flange and the object a engagement edge of overlapping; Can realize that the erecting bed need not pin hole processing, reduce difficulty of construction, improve operating efficiency, simultaneously the utility model also is suitable for two articles and joins situation when making the pin-and-hole processing difficulties.
Description of drawings
Fig. 1 is the utility model implementation result figure.
Fig. 2 is the utility model circle nested structure schematic representation.
Embodiment
Among the figure: 1-circle cover; The 2-flange; 3-overlaps body; The 4-bearing pin; 5-object a; 6-object b.
Below in conjunction with accompanying drawing the utility model is further explained, but the utility model is not limited to following embodiment: open the purpose of this utility model is intended to protect all changes and improvements in the utility model scope.
Among Fig. 1, existing object a5 need position on object b6, during manufacturing, processes pin-and-hole on object b6, at object a5 processing through hole; Process circle cover 1 simultaneously, in conjunction with Fig. 2, circle cover 1 need have flange 2 and cover body 3, and there is through hole at circle cover 1 middle part on axially; At this moment, circle cover flange 2 external diameters need greater than object a5 through-hole diameter, and circle condom body 3 external diameters need less than object b6 through-hole diameter.
Object a5 is after object b6 assembling and determining the position, bearing pin 4 epimeres are cooperated with circle cover through hole, and will justify cover and 1 place in the object a5 through hole, realize that simultaneously the bearing pin hypomere cooperates with the pin-and-hole of object b6, accurately adjust object a5, object b6 position by the gap between circle condom body 3 and object a5 through hole afterwards; Last circumferentially welding circle cover flange 2 and object a5 engagement edge, the accurate location that can realize object a5, object b6.
