Abstract
The utility model discloses an expanding pin, which comprises a pin body, wherein the pin body comprises a fixed positioning end and an expanding positioning end, wherein the expanding positioning end is a taper structure, an opening slot which is threaded through an axial central line of a pin body is longitudinally arranged on the expanding positioning end, when in use, the fixed positioning end of the pin body is inserted on one component of a frock or assembly spare parts, then, the expanding positioning end of the pin body is inserted into the other component which is matched with the frock or the spare parts, the frock and the spare parts or two matched spare parts can be closely matched along the insertion of the expanding positioning end due to the arrangement of the taper structure of the expanding positioning end and the opening slot, the assembly precision is improved, and the expanding pin can adapt a plurality of positioning holes with tiny precision deviation, does not need to manufacture the positioning holes precisely for many times, and has very convenient use.
Description
Technical field
The utility model relates to a kind of locating stud, specifically, relates to a kind of required precision pin that rises low, easy to use.
Background technique
At present, the locating stud that machinery assembling is generally adopted is smooth cylindrical, be used with the positioning hole on the component, because it is not yielding, therefore its requirement on machining accuracy is higher, error is arranged slightly, will influence its assembly precision, especially in actual use, because the precision of each locating stud is inconsistent, just cause each to cooperate the positioning hole machining accuracy inconsistent with locating stud, when the processing positioning hole, need repeatedly carry out precision machining to positioning hole, too high to the assembly precision requirement of positioning hole, be difficult to form the product of unified specification, therefore cause the use inconvenience very of this locating stud.
Summary of the invention
Problem to be solved in the utility model provides a kind of required precision pin that rises low, easy to use, can be adapted to a plurality of positioning holes with small accuracy error, improves the assembly precision of component.
For addressing the above problem, the technical solution adopted in the utility model is:
A kind of pin that rises comprises shank, and described shank comprises stationary positioned end and tensioner positioning end, and described tensioner positioning end is a cone structure, vertically is provided with the opening slot by the shank longitudinal center line on the described tensioner positioning end.
Below be the utility model for further improvement of these options:
The diameter of described tensioner positioning end is dwindled to the position away from the stationary positioned end gradually by the position near the stationary positioned end.
When the tensioner positioning end was inserted positioning hole, along with going deep into gradually of inserting, it is tightr that the tensioner positioning end is cooperated with positioning hole, improved assembly precision.
The tapering of described tensioner positioning end is at least 1 degree.
Can improve the tensioner degree of tensioner positioning end.
The inside of described shank is provided with axial hole.
Alleviated the weight of the pin that rises, simultaneously, when having guaranteed that it quenches, inner with the outside intensity of pin that rises is consistent, has reduced its contraction change rate.
The utility model has adopted above-mentioned technological scheme, during use, stationary positioned end with shank is inserted on one of them parts of frock or assembling component earlier, tensioner positioning end with shank is inserted on another parts that match with frock or component then, because the cone structure of tensioner positioning end and the setting of opening slot, make and cooperate closely along with the insertion of tensioner positioning end between frock and the component or between two component that match, improved its assembly precision, the utility model can be adapted to a plurality of positioning holes with small accuracy error, do not need positioning hole is carried out repeatedly precision machining, use very convenient.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Accompanying drawing 1 is the utility model embodiment's a structural representation;
Accompanying drawing 2 is the plan view of accompanying drawing 1.
Embodiment
Embodiment, a kind of pin that rises, comprise shank, described shank comprises stationary positioned end 1 and tensioner positioning end 4, is provided with the boss 3 of annular between described tensioner positioning end 4 and the stationary positioned end 1, and the diameter of described tensioner positioning end 4 is dwindled to the other end away from boss 3 gradually by the end near boss 3, the tapering of described tensioner positioning end 4 is at least 1 degree, the inside of described shank is provided with axial hole 2, as shown in Figure 2, vertically is provided with the opening slot 5 by the shank longitudinal center line on the described tensioner positioning end 4.
During use, stationary positioned end 1 with shank is inserted on one of them parts of frock or assembling component earlier, tensioner positioning end 4 with shank is inserted on another parts that match with frock or component then, because the cone structure of tensioner positioning end and the setting of opening slot 5, make and cooperate closely along with the insertion of tensioner positioning end between frock and the component or between two component that match, improved its assembly precision, the utility model can be adapted to a plurality of positioning holes with small accuracy error, do not need positioning hole is carried out repeatedly precision machining, use very convenient.
