Technical field
The utility model is related to a kind of location and installation tools, and in particular to a kind of installation tool of high-pressure cylinder positioning key.
Background technology
Many high-pressure cylinder connection positioning are general using positioning key and keyway (convex-concave key) mode, positioning key installation method
The fastening bolt then reprocessed using first spot welding key on key, lower cylinder half positioning key in the cylinder facet position be easy into
Row spot welding and processing, but some upper cylinder halves positioning key position crack narrow space, Ren Yuanhe between shelter, inside and outside cylinder
Equipment cannot be introduced into can not be to positioning key spot welding.Installation is compared blindly herein, and high rejection rate, efficiency of assembling are low.Therefore it needs
The installation tool of reasonable design improves productivity and ensures that assembling various aspects of performance reaches product requirement simultaneously.
Utility model content
The utility model provides a kind of high-pressure cylinder positioning key to solve the problems, such as dress key difficulty between steam turbine
Installation tool.
A kind of installation tool of high-pressure cylinder positioning key of the utility model, composition include that left side locating piece, right side are fixed
Position block, right side adjusting shims, left side adjusting shims and several connecting elements, left side locating piece is parallel with right positioner block to be set
It sets, and left side locating piece is connected with right positioner block by several connecting elements, left side adjusting shims and right side adjust pad
Group is arranged between left side locating piece and right positioner block, and left side adjusting shims are divided into on the adjusting shims of right side
It sets, left side adjusting shims stick on the locating piece of left side, and right side adjusting shims stick on right positioner block.
The utility model has the advantages that compared with prior art：
1, the utility model is to utilize cylinder upper half positioning spline and lower half positioning key inter-alveolar distance, the difference of size and position
The above gap is made up away from adjusting shims on the right side of, use and left side adjusting shims, effectively finds upper half positioning key key
Position, method is simple, and accuracy is high.
2, the installation that positioning key is completed by the utility model can ensure installation requirement through this tool of overtesting,
Repair rate and rejection rate are reduced simultaneously, improves production efficiency, shortens assembly period, saves cost.
Description of the drawings
Fig. 1 is the overall structure front view of the utility model.

Gasket group 3 is setting up and down, and left side adjusting shims 4 stick on the locating piece 1 of left side, and right side adjusting shims 3 stick on right side
On locating piece 2.In order to make the positioning surface of locating piece and key fit closely, the surface roughness of the mounting surface of locating piece is in eight grades of essences
Degree or more, it avoids generating gap.
Specific implementation mode two：Embodiment is described with reference to Fig. 1, and present embodiment is that left side locating piece 1 and right side are fixed
The thickness at least 25mm of position block 2.Setting makes left side locating piece 1 and right positioner block 2 have certain rigidity and intensity in this way,
It avoids generating Light deformation when tight, influences the precise positioning of positioning key.Other compositions and connection relation and specific implementation mode
One is identical.
Specific implementation mode three：Embodiment is described with reference to Fig. 1, present embodiment be right side adjusting shims 3 by
The shapes such as 0.03mm, 0.05mm, 0.07mm, 0.10mm, 0.20mm, 0.30mm, 0.40mm and 0.50mm are identical, thickness not
Same gasket superposition composition.Using the preceding numerical value by measurement, calculates, chooses corresponding spacer thickness, adjust pad
Type and quantity can meet the installation requirements of multiple types cylinder alignment key.Other compositions and connection relation and specific implementation mode
One or two is identical.
