Abstract
The utility model relates to a stepped positioning pin, which comprises a positioning pin body. The front end of the positioning pin body is conical while the rear portion is provided with a nut, and a spacer is arranged on the positioning pin body in front of the nut. The stepped positioning pin is characterized in that a boss circling the positioning pin body is arranged in the middle of the positioning pin body. Due to the boss additionally arranged on the positioning pin, the diameter of the middle of the positioning pin is enlarged, strength of the positioning pin is enhanced, the positioning pin body is strengthened and can not be broken after being stressed for a long time, and then, service life of the positioning pin is prolonged and service cost thereof is reduced greatly. During implementing, when the diameter of a positioning pin is smaller than 14mm and the length thereof is larger than the specific limit, the positioning pin can be added with the boss, and the middle of the positioning pin can be thickened. The stepped positioning pin is simple in structure, reasonable in design, reliable in performance, obvious in effect, wide in application and applicable to various industries such as mechanical manufacturing.
Description
Technical field
The utility model relates to the positioning means in a kind of automobile making, particularly a kind of cascade locating stud.
Background technique
Welding fixture is subordinate to nonstandard industry, particularly auto manufacturing and need requires to carry out independent design and manufacturing according to vehicle, and every anchor clamps often have the uniqueness of self.Usually for middle small jig, the usual practice on the industry is the positioning hole designs fix locating stud according to appointment.At present, if normally used locating stud length is long, after work a period of time, the phenomenon that fractures through regular meeting.
Therefore, providing a kind of simple in structure, significant cascade locating stud of practical effect, is one of these those skilled in the art problem that should address.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of simple in structure, reasonable in design, effect is remarkable, widely used cascade locating stud.
The technological scheme that the utility model adopted is for achieving the above object: a kind of cascade locating stud, comprise the location shank, and described location shank front end is coniform, and the rear portion is provided with nut, and is provided with pad on the shank of the location of nut front; The intermediate portion loop mapping shank that it is characterized in that described location shank is established a boss.
The beneficial effects of the utility model are: after this locating stud is set up boss, make the enlarged diameter of location shank intermediate portion, thereby gain in strength, reinforce shank, effectively avoid locating the long-term generation of phenomenon that fractures after stressed of shank, thereby increase the service life, reduce user cost greatly.The utility model is simple in structure, and is reasonable in design, reliable performance, and the practical effect highly significant, and be applicable to industry-by-industries such as machine-building, use very extensive.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 nut, 2 pads, 3 boss, 4 location shanks.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to embodiment, structure, feature that foundation the utility model provides:
As shown in Figure 1, a kind of cascade locating stud comprises location shank 4, and described location shank 4 front ends are coniform, and the rear portion is provided with nut 1, and is provided with pad 2 on the location shank 4 of nut 1 front; The intermediate portion loop mapping shank 4 that it is characterized in that described location shank 4 is established a boss 3.
Working principle: when location shank 1 diameter during greater than specified limits, can be set up boss 3 less than 14mm, length L, the diameter of position, overstriking intermediate portion, thus effectively strengthen the intensity of location shank 1.
Above-mentioned with reference to embodiment to the detailed description that the cascade locating stud carries out, be illustrative rather than determinate; Therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection domain of the present utility model.
