Abstract
The invention provides a combined vane simulation assembly measuring tool, which can have small volume, low cost and long production period. Furthermore, the invention also provides a measurement method for the combined vane simulation assembly. The assembly measuring tool comprises a simulation assembly block; the dimension of the assembly block is consistent to that a turbine main shaft wheel trough which contains three vanes which are assembled together; the simulation assembly block is arranged on a base; one side of the simulation assembly block is provided with a positioning block used for restricting the vanes; the bottom of the simulation assembly block is provided with a forcing screw; the other side surface of the simulation assembly block is provided with a pressing block. In the measurement method, the three vanes are arranged into the simulation assembly block along the wheel trough on the simulation assembly block; the position of the vanes in the simulation assembly block is restricted by the positioning block which is arranged on the side surface of the simulation assembly block; furthermore, the root working surface of the vane and the working surface of the wheel trough on the simulation assembly block are closely combined together by the forcing screw so as to simulate the connection between vanes and the wheel trough on the main shaft; finally, three vanes are tightly pressed together by the pressing block on the side surface of the simulation assembly block; therefore, the state where the middle vane on a clamp is arranged is just the state of each vane after a ring of vanes are assembled on the main shaft.
Description
(1) technical field
The present invention relates to combination type vane simulated assembly measuring tool, the invention still further relates to the measuring method of combination type vane simulated assembling.
(2) background technology
Vane simulated assembling is the production quality control means taked of each blade production firm in recent years.The simulation assembling of traditional blades is carried out in steam turbine main engine plants.After main engine plants' buying blade, blade directly is assembled on the turbine spindle, or is assembled on the race annulus that is connected with blade on the simulation turbine spindle.According to assembling situation and Design of Steam Turbine requirement, blade is carried out repair one by one, thereby guarantee the qualified of final blade assembling.In recent years, each steam turbine main engine plants is in order to enhance productivity, and requires blade manufacturing enterprise after producing blade, and blade is simulated assembling, and will put in order that the repair of circle blade is qualified to reach the whole matching requirements of steam turbine.If blade manufacturing enterprise by classic method simulation assembling blade, needs to produce main shaft and the whole circle race annulus that uses on the steam turbine main frame.These workpiece are bulky, purposes is single (can only simulate the assembling particular vane), cause the waste of very big metal material, the rising of production cost and the prolongation of production cycle.
(3) summary of the invention
At the problems referred to above, the invention provides combination type vane simulated assembly measuring tool, it is can volume small and exquisite, and cost is low, and the production cycle is long, and for this reason, the present invention also provides the measuring method of combination type vane simulated assembling.
Its technical scheme is such:
Combination type vane simulated assembly measuring tool, it comprises the simulation assembling block, the size of described assembling block and the consistent size of holding the turbine spindle race that three blades are assembled together, described simulation assembling block is loaded on pedestal, simulation assembling block one side is provided with the limit blade locating piece, the bottom of simulation assembling block is provided with and holds out against screw, and the another side of simulation assembling block is provided with compact heap.
The measuring method of combination type vane simulated assembling, it is characterized in that: three blades are packed into along the race on the simulation assembling block, the position of locating piece limit blade in the simulation assembling block with simulation assembling block side, by holding out against screw blade root workplace and the race workplace of simulating on the assembling block are closely linked again, the simulation blade is connected with race on the main shaft, at last with the compact heap of simulating the assembling block side, three blades are pressed together, like this, the residing state of a slice blade in the middle of on the anchor clamps, exactly after assembling a circle blade on the main shaft, the state of each sheet blade.
Adopt said method and special measuring tool, can simulate assembling to blade easily, whole process is convenient and swift, owing to only need hold the quality that three blades just can detect blade, the volume of whole measuring tool is little, and production cost is low, with short production cycle, convenient enforcement.
