Abstract
The utility model discloses an inflation formula pin relates to the machine part field, and this inflation formula pin's pin shell -side face is opened has the centre bore, and the centre bore interpolation has the electric heat plug, and the both ends of electric heat plug all are equipped with the lug, and the wiring hole has all been opened at two lug centers. In can be earlier during the use installing the cotter hole with the shell of pinning, inserting the electric heat plug again in the centre bore, through the wiring hole switch on line of two lugs, heating the electric heat plug, the pin shell is made by insulating material, can effectively prevent the electric leakage, electric heat plug and the pin shell afterexpansion that is heated, alright closely laminate with the cotter hole, effectively ensured this pin positioning's accuracy.
Description
Technical field
This utility model relates to machine components field, particularly to a kind of expansion type pin.
Background technology
In machinery industry, pin is the part done by cylindrical metal or other materials, espespecially in order to be fixed together by several single objects or to be suspended in the supporter on another object as an object.Pin is commonly used to be accurately positioned, and prevents the parts connected to be mutually displaced.
Existing pin designs simply mostly, the most only cylindrical structural, and pin, after repeatedly handling, is often relaxed, had influence on being accurately positioned of pin.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of expansion type pin, arranges electric heating plug in pin shell, and be energized post-heating, makes pin expand, and increases the location accuracy of pin.
For achieving the above object, the technical scheme that this utility model offer is following: a kind of expansion type pin, it is characterized in that: described expansion type pin includes the pin shell of cylinder, pin shell-side face has centre bore, centre bore be cross section be criss-cross through hole, being inserted with cross section in centre bore is criss-cross electric heating plug, electric heating plug and centre bore interference fits, the length of electric heating plug is equal with the length of pin shell, and the two ends of electric heating plug are equipped with lug plate, and two lug plate centers all have wiring hole.
Preferably, described pin shell is manufactured by polyimide material.
Preferably, described electric heating plug and lug plate are by Fe-based perovskite-like oxide manufacture.
Preferably, described two lug plates and electric heating plug are monolithic construction, and wiring hole is manhole.
Using above technical scheme to provide the benefit that: the pin shell-side face of this expansion type pin has centre bore, be inserted with heating core rod in centre bore, the two ends of electric heating plug are equipped with lug plate, and two lug plate centers all have wiring hole.First pin shell can be installed in pin hole during use, it is inserted into electric heating plug again toward centre bore, switched on power line by the wiring hole of two lug plates, electric heating plug is heated, pin shell is manufactured by insulant, can effectively prevent electric leakage, and electric heating plug and pin shell expand after being heated, just can fit tightly with pin hole, the elaboration of this pin of effective guarantee location.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in further detail.
Fig. 1 is the front view of this utility model a kind of expansion type pin；
Fig. 2 is the left view of this utility model a kind of expansion type pin.
Wherein, 1 pin shell, 2 electric heating plugs, 3 lug plates, 4 centre bores, 5 wiring holes.
Detailed description of the invention
Describe the preferred implementation of this utility model a kind of expansion type pin below in conjunction with the accompanying drawings in detail.
Fig. 1 and Fig. 2 shows the detailed description of the invention of this utility model a kind of expansion type pin: this expansion type pin includes the pin shell 1 of cylinder, pin shell 1 side has centre bore 4, centre bore 4 be cross section be criss-cross through hole, being inserted with cross section in centre bore 4 is criss-cross electric heating plug 2, electric heating plug 2 and centre bore 4 interference fits, the length of electric heating plug 2 is equal with the length of pin shell 1, the two ends of electric heating plug 2 are equipped with lug plate 3, two lug plate 3 centers all have wiring hole 5, and wiring hole is used for fixing connection power lead.
In conjunction with Fig. 1 and Fig. 2, pin shell 1 is manufactured by polyimide material, and polyimide material is high-temperature insulation material, and after electric heating plug 2 switches on power, pin shell 1 can play the anti-creeping effect of insulation.Electric heating plug 2 and lug plate 3 are by Fe-based perovskite-like oxide manufacture, and electric heating plug 2 can produce heat and volumetric expansion after switching on power.Two lug plates 3 are monolithic construction with electric heating plug 2, and wiring hole 5 is manhole.
First pin shell 1 can be installed in pin hole during use, it is inserted into electric heating plug 2 again toward centre bore 4, switched on power line by the wiring hole 5 of two lug plates 3, electric heating plug 2 is heated, pin shell 1 is manufactured by insulant, can effectively prevent electric leakage, and electric heating plug 2 and pin shell 1 expand after being heated, just can fit tightly with pin hole, the elaboration of this pin of effective guarantee location.
Above is only preferred implementation of the present utility model; it should be pointed out that, for the person of ordinary skill of the art, on the premise of creating design without departing from this utility model; can also make some deformation and improvement, these broadly fall into protection domain of the present utility model.
