Abstract
A kind of easy-to-dismount locating stud, comprise the cylindrical body of locating stud, the outer side wall of cylindrical body upper end forms one group of relative grooving, grooving runs through cylindrical upper-end surface, on described cylindrical body grooving place vertical tangent plane on form the teeth groove of some roads level, teeth groove is vertically distributed on cylindrical vertical tangent plane, and the cylindrical horizontal section of teeth groove lower end forms positioning groove; Spacing between two vertical tangent planes relative on described cylindrical body is greater than cylindrical diameter; The length of grooving is less than 1/2 of cylinder length.It is improved by the locating stud in standard, when intensity and the positioning performance of minimal effects locating stud, position by two tangent planes on cylindrical positioning pins and step up, thus locating stud of conveniently dismantling, thus reduce in unloading process the loss caused is damaged to component corresponding on diesel engine.
Description
Technical field:
The utility model relates to the technical field of locating stud, more specifically to the easy-to-dismount locating stud of one.
Background technique:
The locating stud that diesel engines at present uses generally is standard piece, and it is easy to use, but when component are disassembled inconvenient or extremely difficulty disassemble.And when disassembling, when locating stud is arranged on the higher plane of seal request, as positions such as end faces on cylinder body, sealing surface may be damaged to disassembling in process, thus cause originally can to scrap process by the component that use of secondary, cause the wasting of resources.On current market, there is a kind of locating stud of chamfered edge type simultaneously, it is exactly on the cylndrical surface of original cylindrical positioning pins, prolong axis milling four planes, its cross section is assumed diamond in shape, retain one group of relative small cylindrical surface, but this kind of locating stud taking-up for convenience detach, but this locating stud amount of cutting strengthens, and have lost intensity and the positioning performance of locating stud to a certain extent.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of easy-to-dismount locating stud, use for convenience detach when its intensity at minimal effects locating stud and positioning performance.
Technology solution of the present utility model is as follows:
A kind of easy-to-dismount locating stud, comprise the cylindrical body of locating stud, the outer side wall of cylindrical body upper end forms one group of relative grooving, grooving runs through cylindrical upper-end surface, on described cylindrical body grooving place vertical tangent plane on form the teeth groove of some roads level, teeth groove is vertically distributed on cylindrical vertical tangent plane, and the cylindrical horizontal section of teeth groove lower end forms positioning groove;
Spacing between two vertical tangent planes relative on described cylindrical body is greater than cylindrical diameter; The length of grooving is less than 1/2 of cylinder length.
The outside of described cylindrical body lower end surface forms chamfering.
Described positioning groove is positioned at the center of cylindrical horizontal section, and the teeth groove on the upside of positioning groove is evenly distributed on cylindrical vertical tangent plane.
The beneficial effects of the utility model are:
It is improved by the locating stud in standard, when intensity and the positioning performance of minimal effects locating stud, position by two tangent planes on cylindrical positioning pins and step up, thus locating stud of conveniently dismantling, thus reduce in unloading process the loss caused is damaged to component corresponding on diesel engine.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 of the present utility modelly changes angled arrangement schematic diagram;
Fig. 3 of the present utility modelly changes angled arrangement schematic diagram.
In figure: 1, cylindrical body; 11, grooving; 12, teeth groove; 13, positioning groove; 14, chamfering.
Embodiment:
Embodiment: see shown in Fig. 1 to 3, a kind of easy-to-dismount locating stud, comprise the cylindrical body 1 of locating stud, the outer side wall of cylindrical body 1 upper end forms one group of relative grooving 11, grooving 11 runs through the upper-end surface of cylindrical body 1, on described cylindrical body 1 grooving 11 place vertical tangent plane on form the teeth groove 12 of some roads level, teeth groove 12 is vertically distributed on the vertical tangent plane of cylindrical body 1, and the horizontal section of the cylindrical body 1 of teeth groove 12 lower end forms positioning groove 13;
Spacing between two vertical tangent planes relative on described cylindrical body 1 is greater than the diameter of cylindrical body 1; The length of grooving 11 is less than 1/2 of cylindrical body 1 length.
The outside of described cylindrical body 1 lower end surface forms chamfering 14.
Described positioning groove 13 is positioned at the center of the horizontal section of cylindrical body 1, and the teeth groove 12 on the upside of positioning groove 13 is evenly distributed on the vertical tangent plane of cylindrical body 1.
The number of the circular hole of the bolt through-hole 21 that described composition kidney-shaped is poroid is 4 ~ 5.
Working principle: conventional locating stud, as cylinder type, conical-surface type, chamfered edge type locating stud all there is dismounting inconvenience or be easy accessibility and lose the problem of certain locating stud intensity or performance, and the locating stud mentioned in this patent compensate for above-mentioned deficiency to a certain extent.
The locating stud of general cylinder type also can be disassembled, but when disassembling, locating stud is not easy to fix, clamp, and may be damaged to sealing surfaces during taking-up;
Take out although chamfered edge type locating stud is also convenient, this locating stud have lost intensity and the positioning performance of locating stud to a certain extent;
Locating stud in this patent is while minimal effects locating stud intensity and positioning performance, by the vertical tangent plane that two on the tool holder locating studs such as conventional needle-nose pliers are relative, teeth groove 12 can match with the tooth of needle-nose pliers, and positioning groove 13 carries out settling the tip of needle-nose pliers, thus carry out rotation and extract.
