Description
Technical field
The utility model belongs to a kind of grinding device, more particularly to a kind of polishing suitable for aircraft fuel oil conduit cavity fills
It sets.
Background technology
The welding procedure of fuel duct is extensive in aircraft manufacturing and aircraft repair sector application, the welding point form of conduit
It is single-side welding double-side forming.In order to meet the accuracy of manufacture and Requirements of Nondestructive Testing of aircraft conduit, pipe inner wall does not allow
There are weld reinforcements.In the repair procedures of aircraft fuel oil conduit, due to needing the position partial distance catheter port of repair welding
The problem of distance is uncertain, both there are problems that knife accessibility of polishing in bruting process, and there is also polishing precision.Currently, whole
Polishing cutter head reachability requirements can be met without a kind of device in a aeronautical manufacture and aeronautical repair industry, while also can not be right
Conduit cavity is precisely polished.
Invention content
The purpose of this utility model is：A kind of conduit cavity weld reinforcement grinding device is provided, aircraft fuel oil conduit is used for
Inner cavity weld seam reinforcement polishing, to reach the accuracy of manufacture and Requirements of Nondestructive Testing.
The technical solution of the utility model is：A kind of conduit cavity weld reinforcement grinding device, including power plant, fastening
Device, branch sleeve, end fixes sleeve, transmission shaft and grinding head；
More than one cartridge unit is affixed successively to form the branch sleeve, more than one axle unit affixed formation institute successively
State transmission shaft；
The power plant is fixed on inside the clamp device, and the transmission shaft is mounted on the connector sleeve by bearing
In cylinder, described transmission shaft one end is connect after stretching out the branch sleeve with the power output end of the power plant, and the other end is stretched
The grinding head is connected after going out the branch sleeve；One end of the branch sleeve is fixedly connected with the clamp device, another
End is fixedly connected with the end fixes sleeve；Bearing is equipped between the end fixes sleeve and the transmission shaft.
Advantageous effect：
The utility model can be by adjusting the axle unit of the quantity and formation transmission shaft for the cartridge unit for forming branch sleeve
Quantity adjust the entire length of grinding device, and then control the depth that can be polished, realization precisely polishes to conduit cavity；
The utility model neatly can fix and dismantle power plant by being provided with clamp device.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Wherein：1- trip bolts；2- taper fixing devices；3- branch sleeves；The ends 4- fixes sleeve；5- transmission shafts.
Specific implementation mode
With reference to the accompanying drawings and examples, the utility model is described in detail.
A kind of conduit cavity weld reinforcement grinding device, it includes：Power plant, clamp device, branch sleeve 3, end
Fixes sleeve 4, transmission shaft 5 and grinding head；
Branch sleeve 3 is formed by one or more by the cartridge unit that screw thread sequentially coaxially connects；Transmission shaft 5 is
It is formed by the axle unit that screw thread sequentially coaxially connects by one or more；The length of transmission shaft 5 and 3 length of branch sleeve
Match, the entire length of grinding device can be changed by adjusting the quantity of cartridge unit and axle unit.
In this example, power plant selects pistol type electric drill；Power plant, which is located at, to be fixed on inside clamp device；Transmission shaft 5
It is mounted in branch sleeve 3 by bearing, the power output end of 5 one end of transmission shaft and power plant connects, and the other end, which is located at, to be connected
3 outside of female connector cylinder has simultaneously been connected through a screw thread grinding head；One end of branch sleeve 3 is fixedly connected with clamp device, the other end with
End fixes sleeve 4 is fixedly connected；It is again provided with bearing between end fixes sleeve 4 and transmission shaft 5；Bearing and transmission shaft 5 it
Between be clearance fit, bearing and branch sleeve 3 are stated between end fixes sleeve 4 as interference fit.
Further, clamp device includes：Trip bolt 1 and taper fixing device 2；Power plant is fixed positioned at taper
In device 2, and fixed by trip bolt 1.Meanwhile taper fixing device 2 is equipped with circular hole, for fastening electricity by screwdriver
It bores and transmission shaft 5.
To sum up, the above is only the preferred embodiments of the present utility model only, is not intended to limit the protection of the utility model
Range.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should be included in
Within the scope of protection of the utility model.
