Abstract

The utility model belongs to the structural technical field of missile launching machinery in the fire control system of airplanes and especially relates to a special tool for missile launchers, which comprises a connecting body (1) and a threaded push rod (2). The connecting body (1) and the push rod (2) are threadedly connected together. The connecting body (1) is provided with two deflating holes (3). A knurling circular column is connected with a concentric positive hexagonal body so as to form the connecting body (1), while the knurling circular column and the concentric positive hexagonal body are integrally machined. Equal-height concentric screwed holes are arranged inside the hexagonal body. Concentric screwed holes are arranged inside the circular column. The upper end of the circular column is symmetrically provided with two through holes, namely deflating holes (3). The push rod (2) is formed by machining a whole circular column into three segments. The top end of the push rod (2) is provided with a knurling handle and the intermediate segment of the push rod is provided with screw threads. The other end of the push rod is provided with a concentric cylinder. The deflating tool of a missile launcher is designed to be small. When to be connected with the deflating valve of a missile launcher, the deflating tool can be more easily docked with the deflating valve, compared with a conventional longer deflating tool. The working difficulty is reduced especially in cold weather.

Description

Guided missile launcher venting instrument

Technical field

The invention belongs to aircraft fire control system MISSILE LAUNCHING frame for movement technical field, particularly relate to a kind of guided missile launcher specific purpose tool.

Background technology

At present; The many guided missile launchers of active service need use high-purity nitrogen to open hook and auxiliary impelling guided missile; When aircraft extracts, need discharge high nitrogen with anti-error impelling, so before extracting, need to use the venting instrument to discharge the high nitrogen in the guided missile launcher, existing venting instrument is complicated, the high inconvenient machine of cost is equipped with a plurality of venting work; Influence the efficient that the many hanging points of aircraft are exitted simultaneously, influence the carrying out of the work subsequent processing that extracts.To this problem, we design, made new guided missile launcher venting instrument, and are simple in structure, easy to use, with low cost, repeatedly on probation, respond well through aboard.

Summary of the invention

The objective of the invention is:

The purpose of the invention provides a kind of venting instrument of throwing the venting body in the guided missile launcher that more fast bleeds off, and shortens aircraft time, improves the aircraft rate of attendance.

Technical scheme of the present invention is:

Guided missile launcher venting instrument comprises connector 1 and threaded push rod 2, and connector 1 and push rod 2 are linked together by silking; 2 air vents 3 are arranged on the connector 1, and connector 1 is to connect with one heart positive hexahedron on the annular knurl cylinder to form, and the two integral body processes; High concentric threads hole is arranged in the hexahedron etc., the concentric threads hole is arranged in the cylinder, it is air vent that cylinder upper end symmetry has 2 through holes; Push rod 2 is to be processed into three sections with whole cylinder; The top is a knurling handle, and the centre is a screw thread, and the other end is a concentric column.

Advantage of the present invention is:

Because the design of guided missile launcher venting instrument is small and exquisite; Long venting instrument is realized and the docking of deflating valve more easily before when being connected with the missile launcher deflating valve, comparing; Especially under cold snap, reduced work difficulty; This device simplicity of design is practical simultaneously, and it is a plurality of to realize that a machine is equipped with, and in the venting work simultaneously of many hangers, has shortened the time of venting work greatly.

The specific embodiment

Guided missile launcher venting instrument comprises connector 1 and threaded push rod 2, and connector 1 and push rod 2 are linked together by silking; 2 air vents 3 are arranged on the connector 1; Connector 1 is the with one heart positive hexahedron that on the annular knurl cylinder of the high 15mm of diameter 30mm, meets the high 11mm of diameter 17mm, and cylinder and hexahedron are an integral body, have in the hexahedron diameter be M8 etc. high concentric threads hole; It is the concentric threads hole of M12mm that diameter is arranged in the cylinder; The through hole that it is 3mm that cylinder upper end symmetry has 2 diameters is an air vent, and push rod 2 is that the cylinder with the whole high 37mm of diameter 15mm is processed into three sections, the knurling handle of the high 10mm of top end diameter 15mm; The centre is the concentric M8 screw thread of long 25mm, the concentric column of the high 5mm of other end diameter 5mm.It is characterized in that connector 1 and push rod 2 are linked together by silking; 2 air vents are arranged on the connector 1; Connector 1 docks with the missile launcher deflating valve through silking; Rotation push rod 2 is a little with the valve jacking in the missile launcher deflating valve, and gas can release from 2 air vents on the connector 1.

Guided missile launcher venting instrument is made up of connector 1 and push rod 2, the silking of the silking in connector 1 column part and missile launcher deflating valve is aligned, because lightly conveniently adjusting in the process that aligns of connector; Comparing original venting instrument docking time shortens; The body that is rotatably connected after aligning is stuck on the hexahedron of connector fasteningly with spanner, accomplish being connected of connector and missile launcher deflating valve; Rotate the knurling handle of push rod 2 then; With push rod 2 rotation direction deflating valves, because there is the annular knurl need just can the jacking of deflating valve valve is not a little with hand by instrument on the handle, high nitrogen discharges after 2 air vents on the connector release in valve.
