Description
Technical Field
The utility model relates to a smooth surface cylinder connecting structure.
Background
In order to meet the requirement of overall flight controllability, a front small wing piece structure is designed to be located on the front connecting cylinder 1, after butt joint is completed, the front connecting cylinder 1 is adjusted to enable the front small wing piece and the rear wing piece to form a certain fixed angle, and in order to guarantee the corresponding relation, the front connecting cylinder 1 and the rear connecting cylinder 2 are connected in a smooth surface mode.
As shown in figure 1, most of the existing smooth surface barrel connecting structures are that a rear connecting barrel 2 is sleeved in a front connecting barrel 1 and is not positioned radially and axially. The structure is easy to loose, so that the relative positions of the front small wing piece and the rear wing piece are changed in the flying process, and the front-stage component even can fall off to influence the flying stability and safety of the aircraft.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problems, the utility model provides a smooth surface cylinder connecting structure which is simple in structure and low in cost, can solve the problem that the connection of the smooth surfaces at the butt joint and joint parts is easy to fall off, and can improve the flight stability and safety of an aircraft.
The technical scheme adopted by the utility model is as follows: a smooth surface cylinder connecting structure comprises a front connecting cylinder and a rear connecting cylinder, wherein a connecting part is arranged at the front end of the rear connecting cylinder and sleeved in an inner hole in the rear end of the front connecting cylinder, the connecting part is in clearance fit with the front connecting cylinder, an annular groove is formed in the side wall of the connecting part of the rear connecting cylinder, a plurality of fastening screw holes are formed in the side wall of the front connecting cylinder corresponding to the annular groove, and fastening screws are arranged in the fastening screw holes.
In the smooth surface cylinder connecting structure, the side wall of the front connecting cylinder is provided with two fastening screw holes which are uniformly distributed along the circumferential direction.
In the smooth surface cylinder connecting structure, the matching surfaces of the connecting parts of the front connecting cylinder and the rear connecting cylinder and the inner surfaces of the annular grooves are coated with bonding glue.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model has simple structure and low cost;
the side wall of the front connecting cylinder at the front end of the rear connecting cylinder is provided with a plurality of fastening screw holes corresponding to the annular grooves, the fastening screws are axially and radially positioned, the connection is reliable, the connecting parts cannot loosen and fall off after long-term storage, and the flight stability and safety of the aircraft are ensured.
Drawings
Fig. 1 is a schematic structural diagram of a conventional smooth surface cylinder connection structure.
Fig. 2 is a schematic structural diagram of the present invention.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 2, the present invention comprises a front connecting cylinder 1 and a rear connecting cylinder 2, wherein the front end of the rear connecting cylinder 2 is provided with a connecting part, and the diameter of the connecting part is smaller than the diameter of the rear part of the rear connecting cylinder 2. The connecting part is sleeved in an inner hole at the rear end of the front connecting cylinder 1, and the connecting part is in clearance fit with the front connecting cylinder 1. Be equipped with annular groove 21 on the lateral wall of connecting portion, be equipped with two tight set screw holes corresponding to annular groove on the lateral wall of preceding connecting cylinder 1, two tight set screw holes along the circumferencial direction equipartition. A set screw 3 is arranged in each set screw hole, and the inner end of each set screw 3 is arranged in the annular groove 21. And adhesive glue is coated on the contact surface of the sleeved part of the front connecting cylinder 1 and the rear connecting cylinder 2 and in the annular groove 21.
When the connecting device is assembled, the matching surface of the connecting part of the rear connecting cylinder 2 and the front connecting cylinder 1 is coated with bonding glue, the annular groove is also coated with the bonding glue, then the connecting device is sleeved into the front connecting cylinder 1 and butted in place, the set screw 3 is coated with a proper amount of bonding glue and screwed into the set screw hole of the front connecting cylinder 1, and the rear connecting cylinder 2 and the front connecting cylinder 1 are connected into a whole after the bonding glue is cured.
