Abstract
The utility model relates to a positioning pin, which comprises a positioning pin body, wherein slots are symmetrically formed in the positioning pin body; a fulcrum shaft is arranged in the middle of each slot; a transverse rod capable of rotating along each fulcrum shaft is arranged on each fulcrum shaft; two ends of each transverse rod are respectively provided with a power block and a limiting stop block; an elastic part is arranged between each limiting stop block and the bottom of each slot; nad a pull ring is arranged on each power block. According to the positioning pin, due to the limiting stop blocks, when running normally, mechanical equipment cannot be separated from a positioning hole because of mechanical vibration, so that the working stability and the working continuity of the mechanical equipment are improved, and the production efficiency is improved. The positioning pin is simply designed and convenient to use.
Description
Technical field
The utility model relates to a kind of locating stud, particularly a kind ofly is used for the locating stud that machinery plays the role of positioning, and belongs to the mechanical parts technical field.
Background technique
In machinery, in the hole of locating stud or the part that connects fastening, mainly play the role of positioning through needs.
But, when the machinery normal operation, can produce mechanical vibration unavoidably; And existing locating stud is generally straight pin; Do not design positive stop, when mechanical shock was excessive, locating stud will be deviate from positioning hole at leisure; Make machinery produce fault, the successional while that influences machinery work has also influenced manufacturing efficiency.
The model utility content
The utility model purpose is that a kind of locating stud that can not deviate from positioning hole because of the mechanical shock that produces is provided for the deficiency that overcomes existing technology.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of locating stud, comprise the locating stud body, and symmetry has groove in the said locating stud body; The intermediate portion of said each groove is provided with fulcrum; Said fulcrum is provided with can be along the cross bar of fulcrum rotation; The two ends of said cross bar are respectively equipped with power piece and positive stop; The base member of said positive stop and groove is provided with elastic member.
Preferably, said power piece is provided with draw ring.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The locating stud of the utility model owing to be provided with positive stop, when the machinery normal operation, can not deviate from positioning hole because of the mechanical shock that produces, and has increased the stability and the continuity of machinery work, and then has improved manufacturing efficiency.
The utility model simplicity of design, easy to use.
Description of drawings
Below in conjunction with accompanying drawing the utility model technological scheme is described further:
Accompanying drawing 1 is the structural representation of the locating stud of the utility model;
Accompanying drawing 2 is the user mode structural representation of the locating stud of the utility model;
Wherein: 1, locating stud body; 2, groove; 3, fulcrum; 4, cross bar; 5, power piece; 6, positive stop; 7, elastic member; 8, draw ring; 9, need the part of location.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The described a kind of locating stud of the utility model shown in accompanying drawing 1 comprises locating stud body 1, and symmetry has groove 2 in the said locating stud body; The intermediate portion of said each groove 2 is provided with fulcrum 3; Said fulcrum 3 is provided with can be along the cross bar 4 of fulcrum rotation; The two ends of said cross bar 4 are respectively equipped with power piece 5 and positive stop 6; Said positive stop 6 is provided with elastic member 7 with the base member of groove 2; Said power piece 5 is provided with draw ring 8.
The described a kind of locating stud of the utility model shown in accompanying drawing 2 during use, at first spurs power piece 5 through draw ring 8; Because lever principle, elastic member 7 is compressed, positive stop 6 retraction grooves 2; Insert in the positioning hole of the part 9 that needs the location then, decontrol draw ring 8 at last, elastic member 7 resets; Positive stop 6 stretches out groove 2, plays spacing effect; In like manner, during dismounting, pulling draw ring 8 is pulled out locating stud then and is got final product from the positioning hole of the part 9 of need location.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The locating stud of the utility model owing to be provided with positive stop, when the machinery normal operation, can not deviate from positioning hole because of the mechanical shock that produces, and has increased the stability and the continuity of machinery work, and then has improved manufacturing efficiency.
The utility model simplicity of design, easy to use.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.
All employing equivalents or equivalence are replaced and the technological scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
