Description
Technical field
The utility model relates to the hydraulic generator stator assembling and uses clamping apparatus, specially refers to a kind of hydraulic generator stator assembling with surveying the circle frame.
Background technology
Big-and-middle-sized hydraulic generator stator is assembled by a plurality of laminated yokes usually, and circle has the enough circularity in guaranteeing stator that laminated yoke is assembled in assembling process, need guarantee that also the center of circle of circle in the stator is coaxial with the center of circle of pedestal ring flat-plate.Usually, adopt and survey the main tool of circle frame as the stator assembling, be used to check the circularity of stator base ring flat-plate, whether inspection dove tail muscle is distributed in the circumference of stator, the circularity of inspection stator lasmination internal diameter.The assembling of prior art hydraulic generator stator comprises parts such as gage beam assembly, bracing frame, pulley assembly, rotary components, counter-jib, center beam barrel and base with surveying the circle frame.It installs and uses process: after modulated good levelness of generator pit and circularity; Stator and base are placed on the same horizontal plane; The center beam barrel is fixedly connected with base; Through the axiality of adjustment center beam barrel of the adjustment screw on the base and stator, guarantee that the center of center beam barrel and stator center overlap.Again all the other each assemblies or parts are installed on the beam barrel of center and can test.During test, drive the whole upper and lower motion of gage beam, counter-jib and bracing frame by motor drive mechanism, thereby the diameter of stator bore of different elevations is checked.Whether rotary components can make the beam barrel rotation around the center of gage beam, counter-jib and bracing frame integral body, be distributed on the same circumference to the radius of each point on the circumference of rounding in the stator, to the radius of round upward each point in the ring flat-plate, to dove tail muscle and measure.Prior art hydraulic generator stator assembling reaches about 4 tons with surveying circle frame overall weight, and its upper and lower moving is accomplished by motor drive mechanism, and the transmission mechanism of whole power is complicacy comparatively, and it moves and the process of rotating is not very smooth and easy.Because the assembly and the parts of whole measuring circle frame are more, mechanism is complicated, and the manufacturing cycle is longer, and manufacturing cost is higher.
Summary of the invention
Bigger with surveying circle frame overall weight for overcoming the assembling of prior art hydraulic generator stator, structure is comparatively complicated, and the manufacturing cycle is longer, and manufacturing cost is than problems such as height, and the utility model proposes a kind of hydraulic generator stator assembling with surveying the circle frame.The assembling of the utility model hydraulic generator stator comprises column, base, positioning component, main support, supporting bracket, connecting rod, horizontal support and gage beam with surveying the circle frame, and wherein, column is fixedly mounted on the base; Locating platform is fixed on the middle and lower part of column, and is provided with cod on last plane; Positioning component is installed on the locating platform of column through cod; A main end that supports connects positioning component, and the other end connects horizontal support; One end of connecting rod connects positioning component through supporting bracket, and the other end connects horizontal support; The other end of horizontal support connects gage beam.
Further, the assembling of the utility model hydraulic generator stator is provided with journal bearing with surveying the circle frame on the top of positioning component.
The assembling of the utility model hydraulic generator stator is to have alleviated the weight of surveying the circle frame greatly with the useful technique effect of surveying the circle frame, is merely the hundreds of kilogram, simplifies the structure, and has shortened the manufacturing cycle, has reduced production cost.
Description of drawings
Accompanying drawing 1 is that the assembling of prior art hydraulic generator stator is with the structural representation of surveying the circle frame;
Accompanying drawing 2 is that the assembling of the utility model hydraulic generator stator is with the structural representation of surveying the circle frame;
Accompanying drawing 3 is local enlarged diagrams of A in the accompanying drawing 2.
Below in conjunction with accompanying drawing and specific embodiment the assembling of the utility model hydraulic generator stator is further specified with surveying the circle frame.
Embodiment
Accompanying drawing 2 is the utility model hydraulic generator stator assembling structural representations with survey circle frame, and accompanying drawing 3 is local enlarged diagrams of A in the accompanying drawing 2, and among the figure, 1 is column; 2 is base, and 3 is positioning component, and 4 is main the support; 5 is supporting bracket, and 6 is connecting rod, and 7 is horizontal support; 8 is gage beam, and 9 is locating platform, and 10 is journal bearing.Can know by figure; The assembling of the utility model hydraulic generator stator is with surveying the circle frame; Comprise column 1, base 2, positioning component 3, main support 4, supporting bracket 5, connecting rod 6, horizontal support 7, gage beam 8, locating platform 9 and journal bearing 10, wherein, column 1 is fixedly mounted on the base 2; Locating platform 9 is fixed on the middle and lower part of column 1, and is provided with cod on last plane; Positioning component 3 is installed on the locating platform 9 of column 1 through cod; Main 4 the end connection positioning component 3 that supports, the other end connects horizontal support 7; One end of connecting rod 6 connects positioning component 3 through supporting bracket 4, and the other end connects horizontal support 7; The other end of horizontal support 7 connects gage beam 8.The assembling of the utility model hydraulic generator stator comprises with the installation and application of surveying the circle frame; After modulated good levelness of generator pit and circularity; Column and base are installed together, and the adjustment column is coaxial with support, and the perpendicularity of column and support is transferred in the 0.02mm/m.Installing and locating cover, main support, supporting bracket, connecting rod, horizontal support and gage beam successively, and on gage beam, lay dial gauge.Because positioning component is installed on the locating platform of column through cod, and is provided with journal bearing on the top of positioning component, has guaranteed the level of positioning component and the location of vertical direction, and can rotate along column.And main support, supporting bracket, connecting rod, horizontal support and gage beam all are fixedly mounted on the positioning component, and therefore, in the process of rotating along column, its level can both be able to guarantee with vertical location.When adorning dove tail muscle or support ring flat-plate in the school, the wheel measuring arm arrives dove tail muscle or support ring flat-plate position, with the axiality of dial gauge measurement dove tail muscle or support ring flat-plate, and fastening or welding when arrival requires with it.In detecting stator core during circularity, the iron core because diameter of stator bore has been packed into, internal diameter diminishes; Should take off horizontal support this moment, and gage beam is directly installed on main the support, same; Adopt dial gauge to measure the radius of stator core each point, thereby measure the interior circularity of stator core.Because the assembling of the utility model hydraulic generator stator has long axial length with the gage beam of surveying the circle frame; Dial gauge only needs to move and can check the diameter of stator bore of different elevations at the length direction of gage beam, and does not need positioning component integral body to move axially.Obviously, the assembling of the utility model hydraulic generator stator is to have alleviated the weight of surveying the circle frame greatly with the useful technique effect of surveying the circle frame, is merely the hundreds of kilogram, simplifies the structure, and has shortened the manufacturing cycle, has reduced production cost.
