Abstract
The utility model discloses a welding fixture for straight-welding-type plates for a steam turbine. The welding fixture comprises a fixture body of a structure bigger than a semicircle, wherein one side of the fixture body is provided with a straight side parallel with the centre line, a plurality of T-shaped grooves are disposed in radial arrangement from the central point of the fixture body, and one ends of the T-shaped grooves close to the circle center of the fixture body are provided with tool withdrawal grooves for T-shaped bolts to pass. According to the abovementioned scheme, the fixture body is configured to be circular, so as to enable the fixture to be used to a maximum extent without resulting in waste and to simultaneously save material cost of the welding fixture; the ends of the T-shaped grooves close to the circle center are provided with the tool withdrawal grooves, so as to allow the T-shaped bolts to pass in a convenient manner to clamp the separator plates; the fixture body is provided with a plurality of U-shaped grooves, which can help to rapidly realize accurate positioning of the separator plates and thus ensuring welding quality.
Description
Technical field
The utility model relates to a kind of partition board of steam turbine, relates to specifically a kind of steam turbine directly welded dividing plate welding tooling, belongs to the mechanical engineering field.
Background technology
At present, the welding of directly welded dividing plate is without special tooling, waste time and energy when centering clamps when welding, in addition owing to there is not the reference of standard to supply to proofread and correct, institute is so that the correction accuracy aspect can not be guaranteed, thus can cause welding finish crack after heat-treating, a series of harmful effects such as subsequent fine allowance deficiency.The general cuboid workbench that adopts has the parallel linear T-shape slot of multiple tracks during at present dividing plate welding on the table plane, although this workbench can carry out clamping to dividing plate, precision still is difficult to guarantee, needs the expensive time when stepping up.
Summary of the invention
Problem to be solved in the utility model is for overcoming above-mentioned technological deficiency, and a kind of accurate positioning, the dividing plate welding quality is high, welding efficiency is high steam turbine directly welded dividing plate welding tooling are provided.
In order to address the above problem, the utility model by the following technical solutions:
A kind of steam turbine directly welded dividing plate welding tooling, comprise clamp body, described clamp body is greater than semicircular structure, the one side has the straight flange that parallels with center line, be provided with the T-shaped groove of some radial arrangement by the central point of clamp body, described T-shaped groove is provided with the escape that can pass through for T-shaped bolt near an end of clamp body home position.
Below be further improvement of the utility model:
Circularize on the described clamp body and be arranged with some and the body concentric U-lag of anchor clamps.
The utility model adopts such scheme, described clamp body to be round the setting and frock is used to greatest extent and is unlikely to cause waste, has also saved the material cost of frock simultaneously.End in the close center of circle of T-shaped groove is provided with escape, can conveniently put into T-shaped bolt with the partition body clamping.Clamp body is provided with some U-shaped grooves, can realize fast the accurate location of dividing plate, thereby guarantees welding quality.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment;
Accompanying drawing 2 be in the accompanying drawing 1 A-A to cutaway view;

Accompanying drawing 4 be in the accompanying drawing 1 C-C to cutaway view.
Among the figure: the 1-clamp body; 2-T type groove; The 3-escape; 4-U type groove.
The specific embodiment
Embodiment, such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of steam turbine directly welded dividing plate welding tooling, comprise clamp body 1, described clamp body 1 is greater than semicircular structure, the one side has the straight flange that parallels with center line, is provided with the T-shaped groove 2 of some radial arrangement by the central point of clamp body 1, and described T-shaped groove 2 is provided with the escape 3 that can pass through for T-shaped bolt near an end of clamp body 1 home positions.
Circularize on the described clamp body 1 and be arranged with some the U-lags 4 concentric with clamp body 1.
Described clamp body 1 is round the setting can be used frock to greatest extent and be unlikely to cause waste, has also saved the material cost of frock simultaneously.
End in the T-shaped groove 2 close centers of circle is provided with escape 3, can conveniently put into T-shaped bolt with the partition body clamping.Clamp body 1 is provided with some U-shaped grooves 4, the accurate location that can realize fast dividing plate, thus guarantee welding quality.
During clamping, with rough turn good dividing plate inner and outer ring, be positioned on the clamp body 1, press the T-shaped groove 2 edge lines calibration partition body split line at clamp body 1 center of circle and two ends, calibrate partition body excircle configuration line according to the edge line of U-shaped groove 4 again, the partition body center of circle is overlapped with clamp body 1 center of circle, and high-ranking officers' partition body just in time compresses.Put into T-shaped bolt by escape 3, be placed on appropriate location in the T-shaped groove 2, with pressing plate and nut partition body is compressed.The dividing plate outer shroud is proofreaied and correct according to above-mentioned steps with partition body is the same, puts into stator blade, does trickle adjustment, begins line, the welding stator blade.
