Problems solved by technology

[0005] The existing internal support mechanism of ring members, such as the published patent CN 204584637, proposes an internal support device for sealing and ring welding of 5m storage tanks. The bearing capacity is relatively weak; at the same time, the existing internal support mechanism of the annular member also has certain restrictions in the working environment, such as the published patent CN104400213, which proposes a storage tank circular seam friction stir welding internal support device, which can It can carry a large load, but it can only be supported in a horizontal environment. If the ring-shaped open member is a vertical processing technology, its huge self-weight will be a great burden

Embodiment 1

[0038] Embodiment one: if Figure 1 to Figure 10 As shown, the present invention proposes an inner supporting card device supported by an annular open member, including a fixed frame 1, the bottom flange of which is connected to an external mechanism or the ground, and the fixed frame 1 is installed with a center Drive platform 2, convex radial support mechanism 3, concave radial support mechanism 4 and servo drive mechanism 5.

[0039] The fixed frame 1 includes a fixed frame including a bottom plate 107, a top plate 101, a center frame 102 fixed between the bottom plate 107 and the top plate 101, several guide rails 103 arranged on the center frame 102 and vertically arranged, and several guide rails 103 arranged on the bottom plate 107 and the top plate. Between 101 and vertically arranged fixed guide rods 104 , guide rails 103 and fixed guide rods 104 are arranged around the center frame 102 . The center frame 102 is equipped with a bearing seat mounting plate 105 and a r...

Embodiment 2

[0046] Embodiment 2: A method for using the inner supporting card device supported by the annular open member described in Embodiment 1, comprising the following steps:

[0047] a) Penetrate the top of the fixed frame 1 into the ring-shaped open member, and make some convex correction blocks 307 and some concave correction blocks 407 be located at the corresponding positions of the welding seam of the ring-shaped open member;

[0048] b) Drive the center drive assembly B202 and the center drive assembly C203 to move toward each other through the servo motor 506 corresponding to the center drive assembly B202 and the center drive assembly C203, and drive the concave shape correction block 407 to move toward the inner wall of the annular open member through the main support rod B401, and butt against the inner wall of the annular open member; and

[0049] c) Drive the center drive assembly A201 and the center drive assembly D204 to move toward each other through the servo motor ...

Abstract

The invention discloses an inner support clamping device for an inner support of an annular open component and a using method thereof. According to the technical scheme, the inner support clamping device for the inner support of the annular open component is characterized by comprising a fixing rack, bottom flanges of the fixing rack are connected to an external mechanism or a ground, the fixing rack is provided with a central driving platform, a convex radial supporting mechanism, a concave radial supporting mechanism and a servo driving mechanism. According to the inner support clamping device for the inner support of the annular open component and the using method thereof, supporting rigidity of the inner support mechanism of the component is greatly improved, the precision of the tailend is guaranteed, moreover, the influence of gravity can be omitted, and the inner support clamping device can be used for vertical supporting mechanisms and can also be used for horizontal supporting mechanisms.

Description

technical field [0001] The invention relates to the field of component connection, in particular to an inner support clamping device supported in an annular open component and a use method thereof. Background technique [0002] Annular open components (two-dimensional or three-dimensional), such as the fuel tank section, the middle section of the pressure vessel or other annular open components, are widely used in chemical industry and aerospace. During the assembly process of such components, welding processes are basically adopted, including TIG arc welding and friction stir welding. [0003] In the welding process of the ring-shaped open member, it is necessary to ensure the roundness and coaxiality of the whole ring, so the support tooling is set inside it, and it is necessary to bear all the external loads while meeting the high-precision requirements of the member product. Friction stir welding As far as it is concerned, it puts forward higher requirements for the int...
