DETAILED DESCRIPTION

[0026] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0027] Embodiment one

[0028] Please refer to the drawings Figs. 1-3 A flange fixing tool, comprising:

[0029] The annular base 1 is provided with at least three position adjusting grooves 10, and the side wall of the position adjusting groove 10 is provided with a strip-shaped protrusion 100. The side wall of the position adjusting sliding plate 2 is provided with a plurality of sliding grooves 20 matched with the strip-shaped protrusion 100, and the top surface of the position adjusting sliding plate 2 is provided with a plurality of first screw holes 21. The flange fixing block 3 is in a stepped shape, and at least two groups of stepped holes 30 matched with the first screw holes 21 are arranged at the steps of the flange fixing block 3. One end of the locking bolt is connected with the first screw hole 21 after penetrating through the stepped hole 30.

[0030] The position adjusting sliding plate 2 is slidingly connected in the position adjusting groove 10, and the flange fixing block 3 is fixedly connected to the top surface of the position adjusting sliding plate 2 through the locking bolt. The annular flange blank to be processed is placed on the annular base 1, and a plurality of flange fixing blocks 3 are ensured to be located in the annular flange blank. Then, the position of the flange fixing block 3 is adjusted by changing the position of the position adjusting sliding plate 2, so that the flange fixing block 3 is in contact with the inner circle of the annular flange blank. The position of the annular flange blank is fixed by three or more flange fixing blocks 3. It should be noted that after the position of the flange fixing block 3 is adjusted, the locking of the position adjusting sliding plate 2 is completed by penetrating the locking bolt through one of the first screw holes 21 provided on the position adjusting sliding plate 2. Therefore, at least one first screw hole 21 is reserved to ensure that it is not blocked by the flange fixing block 3. Since the end of the position adjusting sliding plate 2 away from the center of the annular base 1 is located outside the annular base 1 in some cases, the first screw hole 21 near the end of the position adjusting sliding plate 2 close to the center of the annular base 1 is usually reserved as a locking hole.

[0031] Specifically, the side wall of the flange fixing block 3 away from the center of the annular base 1 is provided with anti-skid lines 31. In order to increase the friction between the flange fixing block 3 and the annular flange blank, the anti-skid lines 31 are arranged on the flange fixing block 3.

[0032] Specifically, the position adjusting slide plate 2 is provided with a plurality of first grooves 22 on the top surface, and the flange fixing block 3 is provided with a plurality of first protrusions 32 matched with the first grooves 22 on the bottom surface; in order to further ensure that the flange fixing block 3 and the position adjusting slide plate 2 do not slide relative to each other in the fixed state, the first grooves 22 and the first protrusions 32 are arranged on the position adjusting slide plate 2 and the flange fixing block 3 to match each other.

[0033] Embodiment two

[0034] Please refer to the attached Figs. 4-5

[0035] Considering that the position adjusting slide plate 2 is located in the position adjusting groove 10, it is possible that the position will slide when the annular flange blank is fixed, resulting in that the annular flange blank cannot be fully fixed. Therefore, it is necessary to strengthen the fixing of the position adjusting slide plate 2. Specifically, the position adjusting groove 10 is provided with anti-skid teeth 101 on the bottom surface, and the position adjusting slide plate 2 is provided with meshing teeth 23 matched with the anti-skid teeth 101 on the bottom surface, and the height of the sliding groove 20 is greater than the height of the strip-shaped protrusion 100. By the mutual meshing of the anti-skid teeth 23 arranged on the bottom of the position adjusting groove 10 and the meshing teeth 23 arranged on the ground of the position adjusting slide plate 2, it is ensured that the position of the position adjusting slide plate 2 will not slide after being fixed. At the same time, in order not to affect the normal adjustment of the position adjusting slide plate 2, the height of the sliding groove 20 needs to be greater than the height of the strip-shaped protrusion 100, so as to ensure that the position adjusting slide plate 2 can move in the vertical direction.

[0036] Specifically, when the strip-shaped protrusion 100 is in contact with the bottom surface of the sliding groove 20, the meshing teeth 23 are in a separated state from the anti-skid teeth 101;

[0037] When the strip-shaped protrusion 100 is in contact with the top surface of the sliding groove 20, the meshing teeth 23 are in an engaged state with the anti-skid teeth 101;

[0038] In order to achieve the purpose that the position adjusting slide plate 2 can move in the vertical direction, at least the requirement that the meshing teeth 23 are in a separated state from the anti-skid teeth 101 when the strip-shaped protrusion 100 is in contact with the ground of the sliding groove 20 needs to be met, otherwise the problem that the position adjusting slide plate 2 cannot be adjusted will occur.

[0039] Embodiment three

[0040] Please refer to the attached Figs. 6-7

[0041] Considering that in actual application, there are some flanges with large size, and the position of the flanges cannot be fixed only by the position adjusting slide plate 2 and the flange fixing block 3, but the production of the flanges is small, and the cost of re-customizing the corresponding fixing tool is too high, therefore, it is necessary to make partial improvement on the basis of the existing fixing tool for the situation, specifically, an extension plate 5 is arranged between the position adjusting slide plate 2 and the flange fixing block 3, the length of the extension plate 5 is greater than the length of the position adjusting groove 10, and a plurality of second through holes 50 matched with the stepped holes 30 are arranged on the extension plate 5; the extension plate 5 is additionally arranged between the original position adjusting slide plate 2 and the flange fixing block 3, thereby indirectly expanding the installable range of the flange fixing block 3, and expanding the original installation range of the position adjusting slide plate 2 from the position adjusting slide plate 2 close to the center of the annular base 1 to the position adjusting slide plate 2 away from the center of the annular base 1 to the installation range of the extension plate 5 from the extension plate 5 close to the center of the annular base 1 to the extension plate 5 away from the center of the annular base 1, thereby increasing the practicability of the fixing tool.

[0042] Specifically, a plurality of second protrusions 51 matched with the first grooves 22 are arranged on the bottom surface of the extension plate 5, and a plurality of second grooves 52 matched with the first protrusions 32 are arranged on the top surface of the extension plate 5, in order to ensure that the positions of the position adjusting slide plate 2 and the flange fixing block 3 do not relatively slide during the use of the extension plate 5, the second protrusions 51 and the second grooves 52 are arranged on the top surface of the extension plate 5 and the ground respectively to be matched with the first grooves 22 and the first protrusions 32.

[0043] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
