Abstract

The invention belongs to aircraft steering engine shell installing areas, and in particular to a kind of deep-hole plug installation tool.Including pushing sleeve 1 (1), spring (2), guide rod (3), pushing sleeve 2 (4) composition, pushing sleeve 2 (4) top screw thread is connected with pushing sleeve 1 (1) lower thread, guide rod (3) is installed on inside the cavity of pushing sleeve 1 (1) and pushing sleeve 2 (4), and spring (2) is installed on the shoulder in the middle part of guide rod (3).The tooling is easy to use simple and direct, greatly shortens assembly time, because plug inclination is squeezed into before avoiding, causes stifled cup even shell to scrap, reduces production cost, reduce because of the pollution that disassembly may cause too much.

Description

A kind of deep-hole plug installation tool
Technical field
The invention belongs to aircraft steering engine shell installing areas, and in particular to a kind of deep-hole plug installation tool.
Background technique
Combined type servo actuator is the important component of the flight control system of current China three generations machine, and main control valve is actuation The core component of device, the year delivery quantity of new product main control valve is about 350 masters at present.Master control valve chest is public with LEE before debugging The plug of department's production will block up fabrication hole everywhere, and since part is tiny, installation effectiveness is extremely low, while also causing part rejection Risk.After using the installation tool, the assembly efficiency of part is greatly improved, assembling quality is improved.It is wanted in assembly Height only had into 2mm, diameter only has the stifled core less than 3mm, and being sent to depth is that 13.4mm diameter only has in the deep hole of 3.968mm.This The method of preceding use is:Stifled core is sticked on formed punch head with a little lubricating grease, is sent into the stifled cup in deep hole.After being sent into stifled core, It first has to confirm stifled core whether in place.Plug is often carried over when taking out formed punch, often repeated multiple times.Stifled core is beaten with formed punch When, can only feel whether stifled core is horizontal with feel, be also easy to produce plug inclination and squeeze into, may cause seal failure, block up cup oil leak, very To plane hydraulic system oil leak is caused, cup stifled core is blocked up when reprocessing and is difficult to extract, there is the risk for causing shell to be scrapped.
Summary of the invention
The purpose of the present invention is:Improve deep-hole plug assembly efficiency and assembling quality
Technical solution of the present invention:
The present invention positions plug using plugged exhaust hole, ensure that plug center line be fit into deep hole when Time is able to maintain parallel with stifled cup, and plug is avoided to be tilted into.
Beneficial effects of the present invention:The tooling is easy to use simple and direct, greatly shortens assembly time, before avoiding because stifled Head tilt is squeezed into, and is caused stifled cup even shell to scrap, is reduced production cost, reduces because of the dirt that disassembly may cause too much Dye.
Detailed description of the invention
Fig. 1 is deep-hole plug installation tool figure
Wherein:
1- pushing sleeve 1,2- spring, 3- guide rod, 4- pushing sleeve 2
Specific embodiment
A kind of deep-hole plug installation tool, including pushing sleeve 1 (1), spring (2), guide rod (3), pushing sleeve 2 (4) composition, pushing sleeve 2 (4) top screw thread is connected with pushing sleeve 1 (1) lower thread, and guide rod (3) is installed on inside the cavity of pushing sleeve 1 (1) and pushing sleeve 2 (4), Spring (2) is installed on the shoulder in the middle part of guide rod (3).
Guide rod (3) lower part needle tip position outer dia is slightly less than stifled core exhaust bore dia, and guarantees that 3-5 degree is oblique Degree guarantees that stifled core can be attached to guide rod (3) lower part by frictional force.
Pushing sleeve 2 (4) lower inner diameter is slightly larger than guide rod (3) lower part maximum gauge, and outer diameter is less than mounting hole internal diameter.
Special tooling is designed and produced, setting angle is solved the problems, such as using the positioning of plugged exhaust hole.In use, index finger hand push is dynamic Push rod, push rod compressed spring, the tip of push rod pass through the gas vent for blocking up core after stretching out pushing sleeve 2, slightly exert oneself, and block up the gas vent of core It is just stuck in the tip of cone push rod, with tooling.After stifled core is placed in master control valve plug cup aperture, index finger unclamps, push rod It is retracted under the thrust of spring, stifled core is pushed down by pushing sleeve 2 to be stayed in stifled cup aperture.

Claims (3)
