Description

A drilling tool for processing the transition section base of a gas turbine

Technical field:

The utility model belongs to a drilling tool for processing the transition section base of a gas turbine.

Background technique:

The processing of the gas turbine transition section base before the utility model is usually that the profile is completed by wire cutting, and then the position line of the hole and the position line of the notch are drawn on the parts, and then punched by the scribed line. First drill the positioning hole with a center drill, and then use drills of different diameters to drill countersinking and reaming. After processing, the concentricity and position of the holes are difficult to ensure the assembly accuracy of the two parts, and the holes need to be trimmed, and some parts even have large concentricity deviations, which cannot be repaired and are scrapped.

Utility model content:

The utility model aims at the above problems and provides a drilling tool with high processing efficiency and good processing quality for processing the base of the gas turbine transition section.

In order to achieve the above object, the utility model adopts the following technical scheme. The utility model includes a frame, and the frame is composed of a left vertical plate, a right vertical plate, an upper plate and a bottom plate, and the inner sides of the left vertical plate and the right vertical plate are respectively arranged There is a support frame corresponding to the base; three through holes corresponding to the base are arranged on the upper plate; through holes corresponding to the base are respectively arranged on the left vertical plate and the right vertical plate.

The beneficial effects of the utility model:

1. The quality of the processed parts is good, and the first-time inspection after drilling and reaming is qualified. No waste and reworked products, smooth assembly;

2. High efficiency. Before the improvement, the base of the part can only process two pieces in one working day; after the improvement, the parts do not need to be marked and drilled for positioning holes, and two parts can be installed at a time, which improves the work efficiency by 4 times and reduces the physical labor of workers;

3. Traditionally, three sets of drilling tools and one set of milling machine fixtures are needed to process two kinds of parts. Now only the drilling tools of the present utility model are used instead, and the drilling tools are simple in structure and applicable.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

FIG. 2 is a top view of FIG. 1 .

Detailed ways:

The utility model includes a frame 1, the frame 1 is composed of a left vertical board 9, a right vertical board 3, an upper board 7, and a bottom board 2, and the inner sides of the left vertical board 9 and the right vertical board 3 are respectively provided with supporting frames corresponding to the base 6 4. The upper plate 7 is provided with three through holes 8 corresponding to the base 6; the left vertical plate 9 and the right vertical plate 3 are respectively provided with through holes 5 corresponding to the base 6.

When in use, at first, fix the base 6 of the transition section between the support frame 4 and the upper plate 7 of the drilling tool of the present utility model; 9. The through holes 5 corresponding to the base 6 are respectively provided on the right vertical plate 3, and the base 6 can be drilled.
