Abstract
It is to be related to a kind of helicopter hub horizontal pin assembly tool the invention belongs to assembly tool field.The present invention is sleeved on by hollow piston rod on center-pole, and piston rod, piston, cylinder body and Reversing oil pump component constitute start barrel structure, pass through Reversing oil pump component actuating plunger bar so that piston rod slides to the left along center-pole, and horizontal pin is driven to be fitted into propeller hub.The configuration of the present invention is simple and facilitate that positioning, clamping are stable, work efficiency is high, while the assembly of same type part can be met with seriation.It was verified that after applying the present invention, reducing the assembly difficulty of operator, the working efficiency of horizontal pin assembly is improved, the labor intensity of worker's hand assembled is also mitigated.
Description
Technical field
The invention belongs to assembly tool field, it is related to a kind of helicopter hub horizontal pin assembly tool and its method.
Background technology
The mounting technology level of Helicopter Dynamic Components directly affects the workmanship of helicopter product, meanwhile, with company
Production-scale continuous expansion so that the production assembly work of helicopter hub parts is increasingly heavy.One kind is developed to be used for
Z8 series helicopters propeller hub horizontal pin assembly tool and to find out feasible method very crucial, can be helicopter hub horizontal pin
Assembly provides easily and effectively Working Means.At present without ready-made Method and kit for, assembling process, which uses, directly taps assembly method,
It is time-consuming and laborious, horizontal pin end face and outer circle damage, the scuffing of hole mating surface etc. are often resulted in, part rejection is easily caused to influence product
Workmanship and progress.
Invention content
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 outer circle damage,
Hole mating surface scratches, conducive to the quality and efficiency of pin assembly of improving the standard.
The technical scheme is that：
The present invention provides a kind of helicopter hub horizontal pin assembly tools：
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 and center-pole screw-thread fit, and nut thread is tightened on the right end of center-pole, fixture block is matched with center-pole screw thread
It closes, and fixture block screw thread is tightened on the left end of center-pole；
Piston rod right end is fixed with chuck, and the centre of chuck is provided with through-hole, and center-pole passes through the through-hole, and through-hole
Aperture is less than the outer diameter of nut；
Piston rod, piston, cylinder body and Reversing oil pump component constitute start barrel structure, and the piston rod is fixed with piston
It is integrated；
Positioning sleeve is connected to the left end of cylinder body, and positioning sleeve is sleeved on outside center-pole.
A kind of application method of the helicopter hub horizontal pin assembly tool, including following steps are provided：
Center-pole (6) is sequentially passed through the centre bore of horizontal pin, positioning sleeve, piston rod and chuck, and will pressed from both sides by step 1
Block and nut are threadedly coupled with center-pole to be integrated；So that nut acts against on the right side of chuck so that fixture block acts against a horizontal pin left side
End；
Step 2 passes through 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 into propeller hub.
The beneficial effects of the invention are as follows：
It was verified that after applying the present invention, greatly reducing the assembly difficulty of operator, horizontal pin assembly is improved
Working efficiency also mitigates the labor intensity of worker's hand assembled, and horizontal pin is made to decompose, be not easily susceptible to collide in assembling process
Damage, improves the assembling quality of helicopter horizontal pin, reduces the generation of product quality defect.And apparatus structure letter
It is single, meanwhile, it can be light with seriation, meet the requirement of same type component assembly.
