Abstract
The utility model relates to a stator tooth press plate drilling machine for a hydraulic generator, which is characterized in that the stator tooth press plate drilling machine comprises a horizontal bottom plate and a positioning block, wherein, the positioning block is fixedly arranged at the lower end of the horizontal bottom plate; both sides of the upper center line of the horizontal bottom plate are symmetrically provided with through holes; drill bushes are arranged in the through holes; and center holes matched with the drilled holes are arranged on the drill bushes. The through holes are arranged at the center line of the horizontal bottom plate for accurate positioning, and the position of the center line on the horizontal bottom plate can be observed through the through holes, so the utility model has simple structure, is convenient to be installed and regulated, can realize one-step positioning, saves labor hour, and improves the production efficiency.
Description
Technical field
The utility model belongs to hydrogenerator and makes the field, particularly relates to a kind of hydraulic generator stator tooth support drilling tool.
Background technology
Tooth support in hydraulic generator stator is used for compressing of stator punching, the distribution circle at the tension hole on its tooth support and the string in stator punching hole distance and place is identical, otherwise tension hole on the tooth support and stator punching hole, stretching screw is just worn to be pass by, cause tooth support not installed, for this reason, during tension hole on boring tooth support, need supporting boring bar tool.At present, existing employing is usually made up the boring mold and is processed, and this combination positioner structure complexity is adding combination installation in man-hour inconvenience, on overhead time, and inefficiency, and the high deficiency of cost.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, install easy to adjust, and hydraulic generator stator tooth support drilling tool that can disposable realization location.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Comprise horizonal base plate and locating piece, locating piece is packed in the lower end of horizonal base plate, and the central upper portion line bilateral symmetry of horizonal base plate is provided with through hole, and drill bushing is installed in the through hole, and drill bushing is shaped on the centre bore with the coupling of being holed.
The utility model can also adopt following technical measures:
The upper surface of described locating piece is made as circular-arc, and this circular arc is identical with tooth support inner arc radius, and with one heart.
Described horizonal base plate is positioned at centerline and is provided with through hole.
Described drill bushing and through hole are over-surplus fit structure.
Advantage and the good effect that the utlity model has are: because the utility model comprises horizonal base plate and locating piece, locating piece is packed in the lower end of horizonal base plate, and the upper surface of locating piece is made as circular-arc, and this circular arc is identical with tooth support inner arc radius, and with one heart; This circular arc is as the location benchmark of when boring distribution circle; The central upper portion line bilateral symmetry of horizonal base plate is provided with through hole, and the string distance between this through hole is identical with the string distance in the tension hole of processed tooth support, and drill bushing is installed in the through hole, the centre bore of coupling that drill bushing 4 is shaped on and quilt is holed; For accurate location, be positioned at centerline at horizonal base plate and be provided with through hole, can see through the position that this through hole be observed the center line on the parallel base plate, so said structure is simple, installs easy to adjust, and can disposable realization location, saving man-hour, improved production efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the utility model user mode structural representation.
Among the figure: 1, horizonal base plate; B, horizonal base plate upper surface; C, horizonal base plate center line; 2, locating piece; 3, through hole; 4, drill bushing; 4-1, centre bore 5, through hole, 6, tooth support; D, tooth support center line.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 to Fig. 3, the utility model comprises horizonal base plate 1 and locating piece 2, and locating piece 2 is packed in the lower end of horizonal base plate 1, and the locating surface of locating piece 2 is made as circular-arc, and this circular arc is identical with tooth support 6 inner arc radiuses, and with one heart; This circular arc is as the location benchmark of when boring distribution circle; Horizonal base plate center line B bilateral symmetry is provided with through hole 3, and the string distance between this through hole 3 is identical with the string distance in the tension hole of processed tooth support 6, and drill bushings 4 are installed in the through hole 3, and drill bushing and through hole are the matched in clearance structure, and drill bushing periphery and horizonal base plate point weld; Drill bushing 4 is shaped on and the hole 4-1 that is mated by boring.For accurate location, pricking own centre line C on the horizonal base plate and causing on the B of horizonal base plate upper surface, horizonal base plate center line C is provided with through hole 5, can determine the relative position of horizonal base plate 1 and tooth support according to through hole 5, horizonal base plate center line C and tooth support center line D match and accurately locate, after corresponding installation was adjusted, the utility model and tooth support together were packed on the workbench; Therefore said structure is simple, installs easy to adjust, and can disposable realization location, saving man-hour, improved production efficiency.
