Description
Technical field
The utility model belongs to field of mechanical technique, particularly a kind of locating stud.
Background technique
Locating stud is orientation tool conventional in machining, apply widely in machining, common locating stud is generally fixed, but under intensive work environment, under particularly vibrating more severe working environment, locating stud is easily shaken, thus causes the problem of connection failure between component.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes that a kind of structure is simple, the structure improved locating stud of good stability.
The purpose of this utility model realizes by following technical proposal: a kind of structure improved locating stud, comprise shank, it is characterized in that, main oil-hole is offered along its axial direction at shank, on shank sidewall, radial direction offers some secondary oilholes communicated with main oil-hole, shank sidewall also offers locating slot, in locating slot, nitrile rubber is installed, nitrile rubber is installed with fastening piece and fastening piece part protrudent pin body sidewall, fastening piece comprises engagement portion and two ends, engagement portion and to stretch out the guide portion formed, the end face of two guide portion is plane, guide portion one end has importing angle and imports outer end, angle a little less than shank sidewall, between the guide portion the other end and engagement portion, there is fillet.
Compared with prior art, the utility model by excavating locating slot and be fixed with nitrile rubber in locating slot on shank sidewall, nitrile rubber is installed with fastening piece and fastening piece part protrudent pin body sidewall, by when being arranged on two component that need be connected, engagement portion in fastening piece is tight against in the groove that leans against in the pin-and-hole of component, thus realize the component that two needs are connected and firmly connect, lubricant oil can be directed on shank sidewall by the main oil-hole of shank and secondary oilhole simultaneously, thus there will not be because oxidation reaction causes the situation of getting rusty and making locating stud be difficult to dismounting when ensure that locating stud is arranged in axis hole, and due to the existence of lubricant oil, also the handling of locating stud are facilitated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the using state figure at another visual angle of the utility model.
In figure, 1, shank; 11, locating slot; 12, main oil-hole; 13, secondary oilhole; 2, nitrile rubber; 3, fastening piece; 31, engagement portion; 32, guide portion; 33, angle is imported; 34, fillet.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As depicted in figs. 1 and 2, this structure improved locating stud comprises shank 1, main oil-hole 12 is offered along its axial direction at shank 1, on shank 1 sidewall, radial direction offers some secondary oilholes 13 communicated with main oil-hole 12, shank 1 sidewall also offers locating slot 11, nitrile rubber 2 is installed in locating slot 11, nitrile rubber 2 is installed with fastening piece 3 and outstanding shank 1 sidewall of engagement portion 31 part, fastening piece 3 comprises engagement portion 31 and two ends, engagement portion 31 and to stretch out the guide portion 32 formed, the end face of two guide portion 32 is plane, guide portion 32 one end has importing angle 33 and imports outer end, angle 33 a little less than shank 1 sidewall, there is between guide portion 32 the other end and engagement portion 31 fillet 34.
This locating stud is specially adapted for the reeded component of pin-and-hole tool, when this locating stud is inserted in component, when the fastening piece 3 on locating stud advances to pin-and-hole place, fastening piece 3 is subject to resistance and cannot moves ahead, now knock locating stud by hammer, fastening piece 3 extrudes nitrile rubber 2 and shifts to pin-and-hole inside under the extruding of pin-and-hole inwall, and locating stud so just can be facilitated to continue to move ahead forward.When advancing to the groove in pin-and-hole when engagement portion 31, engagement portion 31 under the effect of nitrile rubber 2 elastic force, be reset to initial position and groove in clamping pin-and-hole everywhere, now locating stud fixes between two component completely.
By excavating locating slot 11 and be fixed with nitrile rubber 2 on shank 1 sidewall in locating slot 11, nitrile rubber 2 is installed with fastening piece 3 and outstanding shank 1 sidewall of fastening piece 3 part, by when being arranged on two component that need be connected, engagement portion 31 in fastening piece 3 is tight against in the groove that leans against in the pin-and-hole of component, thus realize the component that two needs are connected and firmly connect, lubricant oil can be directed on shank 1 sidewall by the main oil-hole 12 of shank 1 and secondary oilhole 13 simultaneously, thus there will not be because oxidation reaction causes the situation of getting rusty and making locating stud be difficult to dismounting when ensure that locating stud is arranged in axis hole, and due to the existence of lubricant oil, also the handling of locating stud are facilitated.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
