Description
Technical field
The present invention relates to aircraft to assemble field, is specifically a kind of rapid installation device and installation method of coaxial aperture bushing.
Background technology
Assemble and repair field in aircraft, the installation of most of part upper bushing be typically use step pin rod and auxiliary with
Apply an axial compressive force with forcing press and carry out pressure installation, or installation, this installation method risk are tapped using wooden mallet
Greatly, what bushing was subject in installation process is the impact force to differ in size, and the size of power is uneven so that footpath easily occurs for bushing
To offset, when offset is more than 0.03mm, it may appear that the phenomenon that hole in piece part is cut in the end face of bushing, cuts in hole in piece part
Bits, part aperture can become larger, and aperture is easily overproof.When aircraft overhaul changes the outfit new bushing, the component of new bushing of waiting to change the outfit can not be from
Decompose on aircraft and be pressed with step pin rod on forcing press, can only change the outfit aboard, generally using wooden mallet
Or the percussion of rubber hammer so that the method that bushing is gradually slided into hole is constructed, it is easy to dress is inclined or injures bushing by a crashing object,
It is even cracked, the flight safety of aircraft is influenced, hammer easily injures the hand of operating personnel by a crashing object in installation process.Therefore,
Explore a kind of rational bushing method for rapidly mounting and device and not only can guarantee that installation quality, but also processing efficiency can be improved, at the same time
Ensure the safety of operating personnel, then meet aircraft assembling and overhaul schedule requirement.
The content of the invention
To solve the above problems, the present invention provides a kind of bushing method for rapidly mounting and device, easy to be reliable, system is used
Cause low, not only can guarantee that installation quality, but also processing efficiency can be improved, meet aircraft assembling and overhaul schedule requirement.
A kind of coaxial aperture bushing rapid installation device, including support mandrel, pushnut, limited block, movable block, baffle,
It is characterized in that it is polished rod that support mandrel one end, which is the screw thread other end, the diameter of polished rod is smaller 0.1mm than bushing inner diameter to be installed, moves
Motion block is sleeved on polished rod, and can be slided along polished rod, and baffle is placed in movable block front end, and limitation movable block comes off from support mandrel,
Limited block and pushnut are sequentially arranged at the threaded portion of support mandrel, pushnut along screw thread rotation move when, promote
Limited block is moved axially so to mobile Block direction.
A kind of coaxial aperture bushing method for rapidly mounting, comprises the following steps：
1 is first sequentially arranged at bushing to be installed and movable block in the smooth bar part of support mandrel, then inserts baffle
In movable block front end；
2 pass through support mandrel the hole in piece part of bushing to be pressed；
3 are sequentially arranged at limited block, pushnut on the screw thread of the support mandrel other end；
Bushing is placed on part orifice position by 4, rotates pushnut, while is withstood baffle limitation support mandrel and radially turned
It is dynamic；
5 pushnuts rotate the thrust produced and promote limited block extrusion sections, while the pressure that movable block produces promotes lining
Set moves in the axial direction, and bushing is gradually advanced in hole, until bushing is moved to precalculated position, completes bushing installation.
The configuration of the present invention is simple, easy to operate easy to be reliable, required operating space is small, can be light by rotating pushnut
Pine completes the installation of coaxial aperture bushing, and the installation quality of bushing has been effectively ensured, operation difficulty greatly reduces, and processes
It is efficient, the economic benefit highly significant during practice.

Specific embodiment
Fig. 1 is the quick device of coaxial aperture bushing, including support mandrel 1, pushnut 2, limited block 3, movable block 4, gear
Plate 5, support mandrel 1 are made of 6 part of screw thread and 7 part of polished rod, and 7 section diameter of polished rod of support mandrel 1 is than bushing to be installed
11 internal diameters and the small 0.1mm of 4 internal diameter of movable block, the two can have slip by oneself in the smooth bar part in support mandrel, and baffle is used to limit
Movable block 4 processed comes off from support mandrel 1, and 1 polished rod of support mandrel, 7 portion tip is provided with two shallow slots 8, and two planes 9 of slot bottom are flat
OK, there is a gap slot 10 in 5 termination of baffle, and the gap slot 10 and support mandrel 1 are clearance fit, and baffle 5 can be installed easily
And dismounting.1 threaded portion of support mandrel is provided with a pushnut 2 and movable block 4, rotates pushnut 2 and is moved along screw thread
When dynamic, an axial thrust is applied with to limited block 3 into nut, so that limited block 3 moves in the axial direction.
Fig. 2 is 1 structure diagram of support mandrel, its structure is broadly divided into three parts, and Part I is screw thread 6, and screw thread is
Metric coarse thread, screw strength is good, can bear very big axial shearing force without damaging；Part II is 7, polished rod
Point, its diameter is more smaller than installation bushing 11 and 4 internal diameter of movable block, general small 0.1mm so that the two can be free in smooth bar part
It is mobile；Part III is shallow slot 8, and two planes 9 of slot bottom are parallel, for installing baffle 5.
Fig. 3 is 5 structure diagram of baffle, and its one end is handle, and the other end has a gap slot 10, the gap slot 10 and branch
Shallow slot 8 on support core axis 1 coordinates, and baffle can be mounted and dismounted easily in support mandrel 1, and when operation can hold by hand
Handle, limitation is determined support mandrel and is radially rotated, while baffle 5 prevents movable block 4 and bushing to be installed from coming off.
Fig. 4 is the quick schematic device of coaxial aperture bushing, when installing bushing, first successively by bushing 11 to be installed and movement
Then baffle 5 is inserted on shallow slot 8 by block 4 on 7 part of polished rod of support mandrel 1, support mandrel 1 then is passed through zero
Part hole, limited block 3 is passed through by 1 threaded portion 6 of support mandrel, then by pushnut 2 on 1 screw thread of support mandrel.During installation,
Bushing 11 is placed on orifice position, pushnut 2 is rotated with spanner, while baffle 5 is withstood with hand, when rotating pushnut 2,
Baffle 5, which can limit, determines 1 radial rotating of support mandrel, and pushnut 2 rotates the thrust produced and promotes 3 extrusion sections of limited block, together
When movable block 4 produce pressure promote bushing 11 move in the axial direction, under the pressure of movable block 4, bushing 11 axially moves
It is dynamic, gradually it is advanced in hole, until bushing 11 is moved to precalculated position, you can bushing installation that installation is complete.
The configuration of the present invention is simple, easy to operate easy to be reliable, required operating space is small, can be light by rotating pushnut
Pine completes the installation of coaxial aperture bushing, and the installation quality of bushing has been effectively ensured, operation difficulty greatly reduces, and processes
It is efficient, the economic benefit highly significant during practice.
