Abstract
The utility model belongs to the manufacturing technology of airplane frocks, particularly a ventilating long circular sleeve used for the positioning purpose, wherein a working long circular hole is arranged at the center of the long circular sleeve. The upper and lower cylindrical surfaces of the working outer circle of the long circular sleeve are respectively equipped with a spacing semicircular hole and a ventilating groove. Due to the adoption of the ventilating long circular sleeve, a long circular positioning pin can be conveniently inserted into a positioning long circular blind hole. Meanwhile, the problems of the inclined positioning of the positioning long circular pin and the difficult insertion of the positioning long circular pin due to the blocked gas emission inside the blind hole are solved, so that the installation precision of a frock is ensured.
Description
Technical field
The utility model belongs to aircraft frock manufacturing technology, particularly relates to a kind of ventilative oval cover that is used to locate.
Background technique
Existing being installed in located oval cover in the blind hole, when the oval pin in location inserts slotted hole work, because the residual gas in the blind hole of part does not have discharging, make the insertion fully of locating stud cause difficulty, even cause locating stud tiltedly to locate the positioning hole that destroys part.
Summary of the invention
The purpose of the utility model is: a kind of ventilative oval cover that is used to locate is provided.
The technological scheme of the utility model is:
A kind of ventilative oval cover that is used to locate has a work slotted hole 1 at the center of oval cover, at the upper and lower cylinder of work cylindrical of oval cover spacing semicircle orifice 2 and ventilating groove 3 are arranged respectively.
The utility model has the advantages that: be convenient to the oval locating stud of insertion in locating oval blind hole, avoided oblique location of the oval pin in location and the interior gaseous emission of blind hole freely not to cause the oval pin insertion in location difficulty, guaranteed the frock installation precision.
Description of drawings
Fig. 1 is the schematic representation of the ventilative oval cover of the utility model, and 1 is the work slotted hole, and 2 is spacing semicircle orifice, and 3 is ventilating groove.
Embodiment:
During use, oval locating stud is inserted in the work slotted hole 1 of oval cover, as the axle center, oval locating stud slowly, is vertically inserted in the work slotted hole 1 of oval cover with the outer garden of the oval locating stud of the work slotted hole of oval cover 1 guiding.At this moment, the residual gas in the blind hole of location is discharged by the ventilating groove 3 of oval cover.Spacing semicircle orifice is used to avoid locating oval pin and tiltedly locatees.Because the residual gas in the work slotted hole 1 of the oval cover in location is smoothly exhausted, insert in the work slotted hole 1 of locating oval cover very convenient so locate oval pin.
Claims (1)
1. a ventilative oval cover is characterized in that, a work slotted hole is arranged at the center of oval cover, at the upper and lower cylinder of work cylindrical of oval cover spacing semicircle orifice and ventilating groove is arranged respectively.
