Abstract
The utility model discloses a kind of axial-flow water-turbine top cover and runner envelope guide vane shaft holes of both drilling jig tool, it is characterized in that being made up of drill jig template, cushion block, positioning bar and ring flat-plate, drill jig template is hollow ring shape, drill jig template is the annular uniform welding cushion block of one side wherein, the uniform welding positioning bar of one side annular of drill jig template welding cushion block, the size of drill jig template, positioning bar and ring flat-plate and size and processing work match, and drill jig template-setup has the hole consistent and consistent with Quick-change drill bush fit dimension with top cover and runner envelope guide vane shaft holes of both form and position tolerance.The utility model makes simple, easy and simple to handle, does not need special equipment just can reach the machining accuracy of design, can reduce production manufacturing cost largely.
Description
Technical field
The utility model relates to a kind of drilling jig tool, more specifically to axial-flow water-turbine top cover and runner envelope guide vane shaft holes of both drilling jig tool.
Background technology
In hydraulic turbine manufacturing, the machining accuracy of the guide vane shaft holes of both of axial-flow water-turbine top cover and the guide vane shaft holes of both of runner envelope, directly affects the mechanical performance of the hydraulic turbine.Specifically; axial-flow water-turbine top cover and runner envelope guide vane shaft holes of both out of plumb by directly have influence on water distributor assemble in the end clearance of stator and gap of vertical surface; causing controlling stator closes dumb, the consequence cannot shut down after water distributor also may be caused to close.So pay much attention to the processing of axial-flow water-turbine top cover runner envelope guide vane shaft holes of both in the industry, the work of the emphasis in process, special same boring equipment and design specialized frock to be dropped into its processing and go to solve, so just cause production cost higher.
Utility model content
The purpose of this utility model overcomes existing deficiency, specialized designs goes out a kind ofly to make simple, to reduce cost of goods manufactured largely axial-flow water-turbine top cover and runner envelope guide vane shaft holes of both drilling jig tool, the perpendicularity problem that this axial-flow water-turbine top cover and runner envelope guide vane shaft holes of both drilling jig tool utilize easy drill jig process principle to solve axial-flow water-turbine top cover and runner envelope guide vane shaft holes of both to process.
The purpose of this utility model is achieved by following technical proposals: axial-flow water-turbine top cover and runner envelope guide vane shaft holes of both drilling jig tool, it is characterized in that by drill jig template, cushion block, positioning bar and ring flat-plate composition, drill jig template is hollow ring shape, drill jig template is the annular uniform welding cushion block of one side wherein, the uniform welding positioning bar of one side annular of drill jig template welding cushion block, drill jig template, the size of positioning bar and ring flat-plate and size and processing work (i.e. axial-flow water-turbine top cover or runner envelope) match, drill jig template-setup has the hole consistent and consistent with Quick-change drill bush fit dimension with top cover and runner envelope guide vane shaft holes of both form and position tolerance.
Enforcement axial-flow water-turbine top cover and runner envelope guide vane shaft holes of both add man-hour, locate with the fit dimension that positioning bar is corresponding with top cover and runner envelope, respective seat graticule is benchmark, hole in drill jig template is that guide vane shaft holes of both adds production orientation, with different drill bushings respectively to the guide vane shaft holes of both drilling and reaming of top cover and runner envelope, reach the object of enforcement like this.
The utility model makes simple, easy and simple to handle, does not need the machining accuracy that just can reach design with special equipment, can reduce production manufacturing cost largely.
Accompanying drawing explanation
Fig. 1 is the utility model most preferred embodiment front view;
Fig. 2 is the utility model most preferred embodiment left view (because figure is comparatively large and be zhou duicheng tuxing, therefore only drawing half);
In figure 1, drill jig template; 2, cushion block; 3, positioning bar; 4, ring flat-plate; 5, hole.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model most preferred embodiment is described.
The utility model most preferred embodiment as shown in Figure 1, axial-flow water-turbine top cover and runner envelope guide vane shaft holes of both drilling jig tool, by drill jig template 1, cushion block 2, positioning bar 3 and ring flat-plate 4 form, drill jig template 1 is hollow ring shape, positioning bar 3 is eight pieces, cushion block 2 is eight pieces, drill jig template 1 is the annular uniform welding cushion block 2 of one side wherein, drill jig template 1 welds the uniform welding positioning bar 3 of one side annular of cushion block, drill jig template 1, the size of positioning bar 3 and ring flat-plate 4 and size and processing work (i.e. axial-flow water-turbine top cover or runner envelope) match, drill jig template 1 is provided with the hole 5 consistent with top cover and runner envelope guide vane shaft holes of both form and position tolerance, hole 5 and consistent with Quick-change drill bush fit dimension.
The use of the utility model axial-flow water-turbine top cover and runner envelope guide vane shaft holes of both drilling jig tool is implemented to be described below:
1, first by the machined surface horizontal positioned Drilling machines bench of axial-flow water-turbine top cover or runner envelope workpiece, again axial-flow water-turbine top cover is inserted in corresponding position to runner envelope guide vane shaft holes of both drilling jig tool, axial-flow water-turbine top cover contacts with the working face of processing work with the cushion block of runner envelope guide vane shaft holes of both drilling jig tool.
2, after the coordinate position of processing work overlaps with the coordinate position of runner envelope guide vane shaft holes of both drilling jig tool with axial-flow water-turbine top cover, utilize the hole on processing work axial-flow water-turbine top cover and runner envelope guide vane shaft holes of both drilling jig tool to be locked, such processing work and axial-flow water-turbine top cover and runner envelope guide vane shaft holes of both drilling jig tool just form entirety.
3, being inserted in by corresponding Quick-change drill bush in the hole of axial-flow water-turbine top cover and runner envelope guide vane shaft holes of both drilling jig tool, operation drilling machine, take drill bushing as the processing that benchmark implements axial-flow water-turbine top cover and runner envelope guide vane shaft holes of both.
