Abstract
The utility model belongs to airplane tooling manufacturing technology, and relates to a lining arranged in a blind hole, which is characterized in that: the outer cylindrical surface of the lining [2] is provided with 1 to 3 air vents [2a] which are parallel to the axes of the lining and run through the upper and lower end faces; the section of the air vents [2a] is a triangle, rectangle or semi-circle; and when the number of the air vents [2a] is greater than 1, the air vents [2a] are evenly distributed along the periphery of the lining. The lining is conveniently pressed into the blind hole; meanwhile, a positioning pin is conveniently inserted into the lining; and the deviation in the process of arranging the lining is avoided, and the installation accuracy is ensured.
Description
Technical field
The utility model belongs to aircraft frock manufacturing technology, relates to a kind of lining that is installed in the blind hole.
Background technique
When existing blind hole lining is installed with pad on the tool locating part,, cause difficulty for press-fiting of blind hole lining, even cause lining to press and tiltedly destroy existing bore hole on the tool locating part because the residual gas of tool locating part blind hole is difficult to discharging.In addition, the blind hole positioning adapter that has press-fited on existing tool locating part in use when tool locating pin insertion blind hole positioning adapter endoporus positions, also can insert difficulty owing to gaseous emission in the blind hole freely not cause locating stud.
Summary of the invention
The purpose of this utility model is: a kind of lining in the blind hole of being installed in of being convenient to install and being convenient to insert locating stud is provided.
The technical solution of the utility model is: a kind of lining that is installed in the blind hole, comprise a lining, it is characterized in that, on the external cylindrical surface of lining, have 1～3 with the air vent lining parallel axes, that connect the upper and lower end face, the cross section of air vent is triangle, rectangle or semicircle, when the quantity of air vent greater than 1 the time, air vent is uniformly distributed along the circumference.
The utility model has the advantages that: be convenient in blind hole, be pressed into lining, simultaneously, be convenient in lining, insert locating stud, deflection takes place when having avoided mounting bush, guaranteed installation precision.
Description of drawings
Fig. 1 is the scheme of installation of the utility model lining.1 is pad among the figure, the 2nd, and lining, the 3rd, have the part of blind hole.
Embodiment
Below the utility model is described in further details.A kind of lining that is installed in the blind hole, comprise a lining 2, it is characterized in that, on the external cylindrical surface of lining 2, have 1～3 with the air vent 2a lining parallel axes, that connect the upper and lower end face, the cross section of air vent 2a is triangle, rectangle or semicircle, when the quantity of air vent 2a greater than 1 the time, air vent is uniformly distributed along the circumference.
Working principle of the present utility model is: referring to Fig. 1,
At first just pad 1 penetrates in lining 2 endoporus, and the outer garden of the blind hole guide bushing 2 of usefulness part 3 slowly, vertically is pressed into lining 2 in the blind hole of part 3 as the axle center.At this moment, the gas in part 3 blind holes is discharged by the air vent 2a on the outer garden cylinder of lining 2.When inserting locating stud, because gas can be from the smooth and easy discharge of air vent 2a, so insert very convenient.
