Description
Technical Field
The utility model relates to a novel ring flange locating pin location structure belongs to ring flange technical field.
Background
In the existing design, the flange plate comprises a positioning pin-free flange plate and a forged flange plate with a positioning pin, and the positioning pin-free flange plate is mainly used for small-size flange plates. The forged flange plate with the positioning pin is directly forged and formed, and is mainly used for a structure with the strength of the pin shaft joint lower than that of a flange plate material. However, for the super-tonnage engineering machinery, in order to meet the strength required by the joint, the strength of the material used for the pin shaft is often higher than that of the flange plate, the flange plate used for the super-tonnage engineering machinery is large in size, the forging cost of the high-strength material is extremely high, and the high-strength material used for the pin shaft is poor in welding performance and cannot be welded on the positioning plate to form a whole. Therefore, the problem of difficult interference fit of the pin shaft always exists in the connection of the flange plates of the large structural parts.
Disclosure of Invention
In order to overcome the weak point of above-mentioned prior art, the utility model provides a novel ring flange locating pin location structure sets up locating pin, locating hole structure on the ring flange, fixes a position two ring flanges through the locating pin.
The utility model discloses a realize through following technical scheme: the utility model provides a novel ring flange locating pin location structure which characterized in that: the positioning pin is embedded into the flange plate, the flitch plate is respectively welded with the flange plate and the positioning pin, the flitch plate is welded with the positioning pin to form a blocking plate, and the positioning pin and the flange plate are fixed to form a flange plate-positioning pin whole.
The locating pin be equipped with two.
The locating pin and the flange plate are in interference fit.
The positioning pin and the flange plate are forged by the same material.
The blocking plate and the flitch are welded and fixed to extrude the positioning pin on the flange plate.
The blocking plate adopts a circular structure.
The circular structure of the blocking plate is welded with the flitch through the circumference.
The flitch adopts the annular structure of narrow top down width, the narrow face of flitch and ring flange welded fastening, the wide face of flitch and closure plate welded fastening.
The diameter of the bottom of the positioning pin is larger than that of the top of the positioning pin.
The thickness of the blocking plate is smaller than that of the patch plate.
The utility model has the advantages that: the problem that the pin shaft of the large structural part is difficult to match is solved, and the flange plate is positioned through an assembly type positioning pin; the situation that the positioning pin cannot be continuously hammered after being hammered into a part is avoided in the field assembling process.

In the figure: 1. a flange plate; 2. pasting a board; 3. positioning pins; 4. and (6) blocking plates.
Detailed Description
Fig. 1 to fig. 3 show a novel positioning structure for flange positioning pins, which is characterized in that: the positioning device comprises a flange plate 1, a flitch plate 2 and a positioning pin 3, wherein the positioning pin 3 is embedded into the flange plate 1, the flitch plate 2 is respectively welded with the flange plate 1 and the positioning pin 3, the flitch plate 2 is welded with the positioning pin 3 to form a blocking plate 4, and the positioning pin 3 and the flange plate 1 are fixed to form a flange plate-positioning pin whole.
The number of the positioning pins 3 is two.
The locating pin be equipped with two.
The positioning pin 3 is in interference fit with the flange plate 1.
The positioning pin 3 and the flange plate 1 are forged by the same material.
The blocking plate 4 and the flitch 2 are welded and fixed to extrude the positioning pin 3 on the flange plate 1. The blocking plate 4 adopts a circular structure. The circular structure of the blocking plate 4 is welded with the flitch plate 2 through the circumference. The flitch 2 adopts the annular structure of narrow top down width, the narrow face of flitch 2 and ring flange 1 welded fastening, the wide face of flitch 2 and closure plate 4 welded fastening. The diameter of the bottom of the positioning pin 3 is larger than that of the top. The thickness of the blocking plate 4 is smaller than that of the flitch plate 2. The narrow face of flitch 2 and ring flange 1 welded fastening, the circular structure of closure plate 4 avoids appearing the unable condition of pounding out of locating pin 3 in the on-the-spot assembling process through the circumference and flitch 2 welding.
Firstly welding the flange plate 1 and the flitch plate 2 into a whole, then hammering the positioning pin 3 into the whole, welding the blocking plate 4 to form a flange plate-positioning pin whole, and then welding the whole on the main chord member, thus solving the problems that the pin shaft cannot be welded and the large structural member is difficult to be in interference fit. And the situation that the positioning pin 3 cannot be continuously hit in or hit out after being hit into a part can be avoided in the field assembly process.
