The fixing tool of mill support electrostatic spraying.
Background technology
IGV (import adjustable vane) is the part for preventing compressor from surge occurs in combustion engine, it is fixed on annular
In wear-resisting support.It is coated with self-lubricating coat in use on the inner hole wall of the wear-resisting supports of IGV, the self-lubricating coat in use in the long-term course of work
Can be worn consumption, need to carry out spraying reparation to the coating, traditional reparation generally uses adhesive tape to coat mode, and which is not
It is only time-consuming longer, and inefficiency.It can solve the above problems if using electrostatic spraying mode, due to the wear-resisting supports of IGV
On in addition to inner wall surface, remaining surface or installation gap need not be sprayed, it is therefore desirable to which designing one kind can protect
Non-spraying face, and the fixing tool of the energy wear-resisting supports of quick-clamping IGV.
Invention content
The purpose of this utility model is to provide a kind of fixing tool for the wear-resisting support electrostatic sprayings of IGV, the toolings
It can not only stablize in electrostatic spray process and clamp the wear-resisting supports of IGV, moreover it is possible to its non-spraying face be protected not sprayed.
The purpose of this utility model is achieved through the following technical solutions:For consolidating for the wear-resisting support electrostatic sprayings of IGV
Determine tooling, including upper padding plate, lower bolster, turntable, spraying shield and multiple supporting rods, multiple supporting rods are connected to upper padding plate
Between lower bolster, on a spinstand, the middle part of lower bolster is equipped with through-hole, is equipped in through-hole for connecting for the lower bolster installation
The locating piece of turntable centre bore is connect, the upper padding plate is equipped with multiple positioning pins for connecting the wear-resisting pivot flanges of IGV, institute
The upper surface that spraying shield is mounted on upper padding plate is stated, is provided with the through-hole of the installation wear-resisting supports of IGV in the middle part of spraying shield, and spray shield
The bottom of cover is provided with the groove to match with the wear-resisting pivot flanges of IGV, sprays and is additionally provided on shield and lacking in the wear-resisting supports of IGV
The big protruding block and small lugs that mouth matches.
Further, the spraying shield offers the installing port for being put into big protruding block and small lugs, big protruding block with it is small
It is bolted in installing port on the outside of convex block, the insides of big protruding block and small lugs is located at corresponding in the wear-resisting supports of IGV
In notch.
Further, the spraying shield is fixed on by multiple quick-speed jigs on upper padding plate.
Further, the lower bolster be equipped with multiple threaded holes arranged in a ring, supporting rod one end by screw thread with
The threaded hole coordinates, and the supporting rod other end is fixedly connected by bolt with upper padding plate.
Further, the locating piece is the cylinder with step.
It is opposite with turntable that the wear-resisting supports of IGV can be accurately positioned by the way that upper padding plate and lower bolster is arranged in the utility model
Position, and shield, small lugs and big protruding block are sprayed by setting, can in spraying process the wear-resisting supports of effective protection IGV it is non-
Spray-coating surface is not sprayed-on.The tooling of the utility model has many advantages, such as compact-sized, stable connection, fixed, convenient for disassembly and assembly.

Specific implementation mode
As shown in FIG. 1 to 3, the fixing tool provided in this embodiment for the wear-resisting support electrostatic sprayings of IGV includes
Backing plate 1, lower bolster 2, turntable 4, spraying shield 8 and multiple supporting rods 3, lower bolster 2 are equipped with multiple arranged in a ring
Threaded hole, 3 one end of supporting rod is threaded and by being connected on lower bolster 2 with the threaded hole, the other end passes through spiral shell
Bolt is fixedly connected with upper padding plate 1, and lower bolster 2 is mounted on by multiple bolts 6 on turntable 4, and the middle part of lower bolster 2, which is equipped with, to be led to
Hole is equipped with the locating piece 5 for connecting 4 centre bore of turntable in through-hole, and locating piece 5 is the cylinder with step, is passed through
Locating piece 5 can accurately position upper padding plate 1, lower bolster 2 and turntable 4 on the same axis.There are three being set on upper padding plate 1
Positioning pin 7 for connecting the wear-resisting pivot flanges of IGV 12.
The spraying shield 8 is mounted on the upper surface of upper padding plate 1, and 8 middle part of spraying shield is provided with the installation wear-resisting supports of IGV
11 through-hole, the wear-resisting outer wall surfaces for supporting 11 of IGV are bonded with the inner wall surface of the through-hole, and the bottom of spraying shield 8 also opens up
There is the groove to match with the wear-resisting pivot flanges of IGV 12, sprays and be additionally provided with three fixture fixing ports 83 on shield 8, pass through installation
Quick-speed jigs 13 can realize being fastenedly connected for spraying shield 8, the wear-resisting pivot flanges 12 of IGV and upper padding plate 1.
In order to protect IGV it is wear-resisting support 11 non-spraying face be not sprayed-on, opened up on the spraying shield 8 there are one be used for
It is put into the installing port 81 and five installing ports 82 for accommodating small lugs 10 of big protruding block 9, big protruding block 9 is outer with small lugs 10
End is bolted in corresponding installing port 81 or installing port 82, and big protruding block 9 and the inner end shape and IGV of small lugs 10 are wear-resisting
The shape of 11 corresponding notches is supported to match, when installation, installing port 81 or installation are stretched out in the inner end of big protruding block 9 and small lugs 10
Mouth 82, and to protect notch surface not to be sprayed-on in 11 corresponding notches of the wear-resisting supports of IGV.
The installation process of the utility model is:Locating piece 5 is put into 4 centre bore of turntable, is exposed by locating piece 5
Lower bolster 2 is located on turntable 4 by step part, tightens bolt 6, then supporting rod 3 and upper padding plate 1 are sequentially arranged at underlay
On plate 2, by positioning pin 7 by the wear-resisting positioning of pivot flange 12 assembly of IGV, spraying shield 8 is then sleeved on the wear-resisting supports of IGV
On 11 outer wall, it is fixed on upper padding plate 1 by quick-speed jigs 13 by shield 8 is sprayed, finally in corresponding installing port 81 or peace
Installation big protruding block 9 and small lugs 10 in mouth 82 are filled, this tooling assembled is fixed on corresponding slewing and completes this work
The location and installation of dress.
The above is only the utility model preferred embodiment, but the scope of protection of the utility model is not limited to
This, any transformation carried out based on technical solution provided by the utility model and inventive concept and replacement should all be covered in this reality
