Abstract
The utility model discloses a kind of alignment pin, comprise dowel body, cone tank is had in dowel body, base is fixed with in the middle part of dowel body, dowel body end is provided with plug-in unit, and its center position has through hole, and this through hole is communicated with cone tank, base evenly has multiple groove, in each groove, is provided with fulcrum.The beneficial effects of the utility model are: structure is simple, easy for installation, locating effect is good, back-up ring serves the effect of buffering, make alignment pin fixing more stable, can effectively prevent from walking, effectively can play the effect of location in optical fiber production process, guarantee positioning precision is stablized, and improves security simultaneously.
Description
Technical field
The utility model relates to a kind of alignment pin.
Background technology
In plant equipment, alignment pin, through in the hole needing part that is fastening or that connect, mainly plays the role of positioning.The alignment pin at this positioning reference holes place should ensure that the positioning precision of part can realize again dismantling at any time.Traditional method for designing is that alignment pin adopts screw thread mounting or dismounting mode, is screwed out by alignment pin after the clamping of part location by screw thread again.Therefore screw thread self precision and reciprocating operation directly can affect Position location accuracy, affect the precision of product.Simultaneously in use easily there is the phenomenon that walks in alignment pin, installs unstable, be unsuitable for the production of optical fiber.
Therefore, for solving the problem, spy provides a kind of new technical scheme.
Utility model content
The utility model provides a kind of alignment pin.
The technical solution adopted in the utility model is:
A kind of alignment pin, comprise dowel body, cone tank is had in described dowel body, base is fixed with in the middle part of described dowel body, described dowel body end is provided with plug-in unit, and described its center position has through hole, and this through hole is communicated with cone tank, base evenly has multiple groove, in each groove, is provided with fulcrum.
Described plug-in unit outside is provided with elastomeric element.
Described elastomeric element is back-up ring.
The beneficial effects of the utility model are: structure is simple, easy for installation, locating effect is good, back-up ring serves the effect of buffering, make alignment pin fixing more stable, can effectively prevent from walking, effectively can play the effect of location in optical fiber production process, guarantee positioning precision is stablized, and improves security simultaneously.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, dowel body, 2, cone tank, 3, base, 4, plug-in unit, 5, through hole, 6, groove, 7, fulcrum, 8, back-up ring.
Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to protection domain of the present utility model.
A kind of alignment pin as shown in Figure 1, comprise dowel body 1, cone tank 2 is had in dowel body 1, base 3 is fixed with in the middle part of dowel body 1, dowel body 1 end is provided with plug-in unit 4, plug-in unit 4 center has through hole 5, this through hole 5 is communicated with cone tank 2, evenly have multiple groove 6 on the base 3, fulcrum 7 is provided with in each groove 6, the effect of location effectively can be played in optical fiber production process, guarantee positioning precision is stablized, improve security simultaneously, plug-in unit 4 outside is provided with back-up ring 8, back-up ring serves the effect of buffering, make alignment pin fixing more stable, can effectively prevent from walking, structure is simple, easy for installation, locating effect is good.
The above; it is only preferred embodiment of the present utility model; not restriction the utility model being made to any other form, and any amendment done according to technical spirit of the present utility model or equivalent variations, still belong to the utility model scope required for protection.
