Abstract
A clamp for measuring throat width of a movable vane of a steam turbine consists of a clamp body, a tenon tooth positioning block, a baffle and a stretched screw; the size of the tooth shape of the tenon tooth positioning block is consistent with the size of the groove of the assembly impeller of a steam turbine; the tenon tooth positioning block and the baffle are fixed on the clamp body by a screw; and the clamp body of the clamp is provided with two positioning troughs which are used for assembling two adjacent tenon tooth positioning blocks. The clamp body of the clamp and the tenon tooth positioning block are made into split structures. During the assembly process, the relative position of the two positioning tooth shapes can be adjusted conveniently by only needing to grind the bottom surface and two side surfaces of the two tenon tooth positioning blocks according to requirements, thereby avoiding increasing the production cost and avoiding prolonging the production period.
Description
Technical field
The utility model relates to a kind of measurement steam turbine blade throat opening SA anchor clamps.
Background technology
Blade is the critical component of steam turbine, the flow of throat opening therebetween (in the leaf grating between adjacent blades the minimum widith of passage) size decision steam flow, and the flow of steam flow will directly influence the generating efficiency of steam turbine.
The measurement of tradition moving vane throat opening size is all carried out in steam turbine main engine plants, manufacturer does not generally measure, in main engine plants, generally be moving vane to be directly installed on the impeller that has corresponding race measure, if it is defective, then need blade is carried out repair one by one, this production efficiency to main engine plants has produced certain influence.If these work are done by manufacturer, then need manufacturer to process these impellers, and these impellers are bulky, purposes is single, and this certainly will cause the waste of the increase of production cost, more material and the prolongation of production cycle to manufacturer.
Summary of the invention
The utility model provides a kind of measurement apparatus of simulation two adjacent moving vane assemblings, and the measurement steam turbine blade throat opening SA that a kind of volume is small and exquisite, easy to adjust, production cost is low, with short production cycle is provided anchor clamps at the problems referred to above.
The utility model is achieved through the following technical solutions:
Measure steam turbine blade throat opening SA anchor clamps, by clamp body, tenon tooth locating piece, baffle plate with hold out against screw and constitute.Race consistent size on tooth proportions that designs on the described tenon tooth locating piece and the steam turbine assembling impeller.Tenon tooth locating piece, baffle plate all are screwed on clamp body.
The clamp body of above-mentioned anchor clamps is provided with two locating slots, is used to assemble two adjacent tenon tooth locating pieces.Clamp body, tenon tooth locating piece also can be designed to one-piece construction, but the relative position of two location profiles of tooth is had relatively high expectations, and processing easily causes scraps.The advantage of clamp body, tenon tooth locating piece design mix body structure is: bottom surface that the relative position of two location profiles of tooth can be by reconditioning tenon tooth locating piece and two sides and be guaranteed easily, thus production cost is reduced, the production cycle obtains shortening.
When measuring steam turbine blade throat opening SA, only need with two adjacent moving vanes pack into be processed with corresponding profile of tooth the tenon tooth locating piece in, hold out against moving vane blade root end face (simulate steam turbine blade finally install state) with holding out against screw, can measure easily.
The beneficial effects of the utility model are: during owing to measurement throat opening SA, only need the assembling of simulation two adjacent moving vanes, so above-mentioned anchor clamps volume is small and exquisite.When the profile of tooth of the location of processing two adjacent moving vanes, because the relative position of two location profiles of tooth is had relatively high expectations, processing easily causes scraps, so the clamp body and the tenon tooth locating piece of above-mentioned anchor clamps are made the branch body structure.During assembling, only need the bottom surface and the two sides of reconditioning two tenon tooth locating pieces as requested, can adjust the relative position of two location profiles of tooth easily, so just avoided the increase of production cost and the prolongation of production cycle.
Description of drawings
Fig. 1 is for measuring steam turbine blade throat opening SA anchor clamps front view.
Fig. 2 is clamp body figure
Fig. 3 is tenon tooth locating piece figure
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As Fig. 1, Fig. 2, shown in Figure 3, measure steam turbine blade throat opening SA and comprise clamp body 1, tenon tooth locating piece 2, baffle plate 3, hold out against screw 4 with anchor clamps.Tooth proportions on the tenon tooth locating piece 2 designs by the race size on the impeller, and tenon tooth locating piece 2 is screwed on clamp body 1; Baffle plate 3 usefulness screws are installed on the clamp body 1, are used for the location of steam turbine blade in the steam output side direction.
When measuring steam turbine blade throat opening SA, two adjacent moving vanes are packed on the tenon tooth locating piece 2 in the profile of tooth of corresponding location, make the moving vane steam output side plane of surveying and baffle plate 3 be close to, what screw clamp body 1 bottom surface holds out against screw 4, hold out against moving vane blade root end face, the pressure-bearing surface of moving vane blade root profile of tooth is closely contacted with profile of tooth on the tenon tooth locating piece 2, at this moment, the state of moving vane is exactly the installation state of impeller race of finally packing into, can measure the throat opening size of moving vane then easily with throat opening SA feeler gauge.
Claims (2)
1, measures steam turbine blade throat opening anchor clamps, it is characterized in that by clamp body, tenon tooth locating piece, baffle plate and hold out against screw constituting; Race consistent size on tooth proportions on the described tenon tooth locating piece and the steam turbine assembling impeller, tenon tooth locating piece, baffle plate all are screwed on clamp body.
2, measurement steam turbine blade throat opening anchor clamps according to claim 1, it is characterized in that: the clamp body of above-mentioned anchor clamps is provided with two locating slots, is used to assemble two adjacent tenon tooth locating pieces.
