Abstract
The invention belongs to the field of assembling tools, and relates to a helicopter propeller hub horizontal pin assembling tool. A center rod is sleeved with a hollow piston rod. The piston rod, a piston, a cylinder body and a reversing oil pump assembly form an actuator cylinder structure. The piston rod is actuated through the reversing oil pump assembly and slides leftwards along the center rod so as to drive a horizontal pin to be mounted into a propeller hub. The assembling tool is simple in structure, convenient to position, stable in clamping and high in working efficiency, meanwhile, serialization can be achieved, and the assembling requirement of parts of the same type is met. Practices show that after the assembling tool is adopted, the assembling difficulty for operating workers is lowered, the assembling operation efficiency of the horizontal pin is improved, and the labor intensity of manual assembling of the workers is relieved.

Waste time and energy, often result in horizontal pin end face and cylindrical damage, the scuffing of hole mating surface etc., easily cause part rejection to affect product
Workmanship and progress.
The content of the invention
The purpose of the present invention is：A kind of helicopter hub horizontal pin assembly tool and method be provided, the tool construction is simple,
It is easy to operate and disclosure satisfy that helicopter hub horizontal pin matching requirements, reduce assembling process horizontal pin end face and cylindrical damage,
Hole mating surface is scratched, beneficial to the quality and efficiency of pin assembling of improving the standard.
The technical scheme is that：
The invention provides a kind of helicopter hub horizontal pin assembly tool：
The helicopter hub horizontal pin assembly tool includes piston rod (1), piston (2), cylinder body (3), Reversing oil pump group
Part (4), fixture block (5), center-pole (6), positioning sleeve (7), chuck (8), nut (9)；
Piston rod is hollow stem, and piston rod is sleeved on center-pole, and can mutually be slided between piston rod and center-pole；
Nut coordinates with center-pole screw thread, and nut thread is tightened on the right-hand member of center-pole, and fixture block is matched somebody with somebody with center-pole screw thread
Close, and fixture block screw thread is tightened on the left end of center-pole；
Piston rod right-hand member is fixed with chuck, and the centre of chuck is provided with through hole, and center-pole passes through described through hole, and through hole
External diameter of the aperture less than nut；
Piston rod, piston, cylinder body and Reversing oil pump component constitute start barrel structure, and described piston rod is fixed with piston
It is integrated；
Positioning sleeve is connected to the left end of cylinder body, and positioning sleeve is enclosed within outside center-pole.
A kind of using method of described helicopter hub horizontal pin assembly tool, including following step are provided：
Step one, by (6) center-pole the centre bore of horizontal pin, positioning sleeve, piston rod and chuck are sequentially passed through, and will be pressed from both sides
Block and nut are threadedly coupled with center-pole and are integrated；So that nut acts against chuck right side so that it is left that fixture block acts against horizontal pin
End；
Step 2, by Reversing oil pump component actuating plunger bar so that piston rod slides to the left with respect to center-pole, and by water
Flat-sale is fitted in propeller hub.
The invention has the beneficial effects as follows：
It was verified that after using the present invention, greatly reducing the assembly difficulty of operator, horizontal pin assembling is improve
Operating efficiency, also mitigates the labour intensity of workman's hand assembled, makes horizontal pin that collision is not easily susceptible in decomposition, assembling process
Damage, improve the assembling quality of helicopter horizontal pin, reduce the generation of product quality defect.And the apparatus structure letter
It is single, meanwhile, can be light with seriation, meet the requirement of same type component assembly.
