The setting of metal plate face, and the pin shaft by passing through pin shaft hole limits, and is additionally provided with bolt hole, two institutes on the metal plate
The metal plate for stating fixing clamp gripping member is fixed by the clamping screw for passing through bolt hole.
When utility model works, the compressor blade repaired will be needed to assemble the middle period between two panels sheet metal
Point repairs position and adds blade tip shape out to fit with the pre- first chance of sheet metal, and manual locking bolt is tightened, molten with laser
It covers and position reparation is repaired to blade tip, heat is guided rapidly by sheet metal in repair process, reaches blade tip rapid cooling
Effect.
Further, the clamping part and fixed part are integrally formed using red copper makes, and production is simple, since scale copper has
Preferable elasticity, deformable blade will not be caused when being bonded blade tip, and can copper sheet be fitted closely with blade.
Further, the clamping part is red copper, and the fixed part is iron, aluminium, titanium, the fixed part and the folder
Portion is held by being welded to connect, since scale copper has preferable elasticity, deformable blade, and energy will not be caused when being bonded blade tip
So that copper sheet is fitted closely with blade, clamping part uses copper sheet, other metals can be used in fixed part, and the two welding can also be real
Now grip effect.
Further, the clamping part of two fixing clamp gripping members is inverted l-shaped structure and axial symmetry, production is easy, with reality
Now to the clamping of compressor blade.
Further, the clamping part of two fixing clamp gripping members is arcuate structure and axial symmetry, is easy production, to realize
Clamping to compressor blade.
Further, two clamping part end contact parts are provided with the gap of blade tip shape, to realize folder
Portion end is held to fit closely with blade tip.
Further, the clamping screw is manual locking bolt, and manual locking bolt is tightened, and does not need complicated knot
Structure.
Further, the pin shaft quantity is 2, is equally spaced with clamping screw, stablizes effectively assembly alignment and fixes.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1, it since copper sheet has preferable elasticity, can be bonded closely with the blade of different-thickness shapes at different levels, strong applicability.
2, fixture is simple and convenient to operate, low manufacture cost.
3, high with blade tip surface fitting degree.Greatly increase the heat dissipation effect of blade in laser cladding process.
