Abstract
The utility model relates to a drilling tool for the end face of an externally-arranged water ring guide vane hole of a hydroturbine generator set, which is characterized by comprising a drill template and a back side shield. The drill template and the back side shield are connected with each other through a countersink bolt assembly. The drill template is equipped with a positioning spigot and a drill jig hole is arranged at the position of the positioning spigot. A matched drill sleeve is arranged inside the drill jig hole. Due to the adoption of the above technical scheme, the drilling and machining of the end face of an externally-arranged water ring guide vane hole can be completed through simple drilling and machining equipment such as a magnetic drill, wherein large-scale machine tools and the processes of marking-out, inspecting and the like are not needed. Therefore, the processes of complicated marking-out, clamping, aligning and the like are simplified so as to reduce the production cost and shorten the construction period.
Description
Technical field
The utility model belongs to hydrogenerator manufacturing technology field, particularly relates to hydraulic generator group outer gate barrel stator hole end surface drilling tool.
Background technology
Outer gate barrel is the emphasis parts of water distributor department of assembly cover in the hydraulic generator unit water machine part.The outer gate barrel flow-passing surface is spherical crown; Be provided with 16 place's movable guide vane installation axle hole in the conventional unit simultaneously; Close connection holes for the installation of movable guide vane end cap with handle on the seam face of aperture; Because the structural form of spherical crown thinks that realization outer gate barrel stator installing hole end face efficient, high-quality is the difficult point in processing and manufacturing field closing connection holes processing all the time.
Summary of the invention
The utility model provides a kind of simple in structure, easy to use, hydraulic generator group outer gate barrel stator hole end surface drilling tool of increasing work efficiency for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of hydraulic generator group outer gate barrel stator hole end surface drilling tool; It is characterized in that: this drilling tool comprises bushing plate; Be connected through the dormant bolt assembly between the dorsal part baffle plate, said bushing plate and dorsal part baffle plate, said bushing plate is provided with positioning spigot; The positioning spigot place is provided with the drill jig hole, and said drill jig is fitted with drill bushing in the hole.
The utility model can also adopt following technical measures:
Said dorsal part baffle plate is provided with fabrication hole.
Said dorsal part baffle plate is provided with the transition oblique angle.
Said bushing plate is provided with fabrication hole.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; Utilize magnetic force to bore this simple and easy boring process equipment and accomplish outer gate barrel stator hole end surface boring processing; Need not to take operations such as heavy duty machine tools equipment and line check; Simplified numerous and diverse line, be installed, operation such as centering, and then reduced production cost, shorten manufacturing schedule.Tentatively standardization of the employed drill bushing of the utility model simultaneously, outer gate barrel stator hole end surface boring processing in follow-up other hydroelectric project is as long as boring specification unanimity can realize boring processing through revising the profile location dimension.The utility model is simple in structure but be skillfully constructed; The design utilization modern project mathematic calculation and the computer-aided manufacturing scientific method of frock; In conjunction with the imitative type of three-dimensional engineering software simulation; Satisfy the requirement of design accuracy to the greatest extent, meet similar problem from now on and can use for reference processing, exist invisible reference to be worth.

The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 to Fig. 5, a kind of hydraulic generator group outer gate barrel stator hole end surface drilling tool, this drilling tool comprises bushing plate 1; Be connected through dormant bolt assembly 3 between the dorsal part baffle plate 2, said bushing plate 1 and dorsal part baffle plate 2, said bushing plate 1 is provided with positioning spigot 1-1; Positioning spigot 1-1 place is provided with drill jig hole 1-2; Be fitted with drill bushing 4 in the said drill jig hole 1-2, in order to alleviate the weight of the utility model, said dorsal part baffle plate and bushing plate are provided with fabrication hole.Said structure adopts the seam location, has the advantage of accurate positioning; And drill bushing is installed in and has selected the tolerance fit that is fit in the bushing plate between the two when practical operation, and then location, import feature when having realized boring finally guarantee the crudy of holing; Dorsal part baffle plate itself also is designed with fabrication hole and 10 ° of transition oblique angles, is easy to observe to install effect in the time of weight reduction, and 10 ° of oblique angles can increase baffle plate and avoid corner angle to contact with the contact area of outer gate barrel 5 inwalls and then guaranteed that the frock connection is fastening.
At first bore template in advance connects one with dormant bolt closing to connect with the dorsal part baffle plate; Then adjust the contact area of the preparatory outer gate barrel inwall of back baffle plate simultaneously with reference to the adjustment of groove location-appropriate; The contact-making surface that as far as possible increases the preparatory outer gate barrel inwall of baffle plate connects and then guarantees to connect fastening; Drill bushing is installed on the bushing plate relevant position, with simple and easy rig--magnetic force bores and is adsorbed on bushing plate central authorities, utilizes bushing plate to realize that positioned magnetic creeps into capable outer gate barrel stator hole end surface boring processing at last.On the basis of satisfying the design accuracy requirement, utilize magnetic force to bore this simple and easy boring process equipment like this and accomplish outer gate barrel stator hole end surface boring processing; Need not to take operations such as heavy duty machine tools equipment and line check; Simplified numerous and diverse line, be installed, operation such as centering; And then reduced production cost, shorten manufacturing schedule.
