DETAILED DESCRIPTION

[0031] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] In order to simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0033] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0034] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0035] like Figure 1-7 As shown, the titanium alloy spherical water tank machining and welding tooling is used to clamp the hemispherical first cabin body 101 and the hemispherical second cabin body 102, the first cabin body 101 has a first through hole 1011, the second cabin body 102 has a second through hole 1021, the first cabin body 101 and the second cabin body 102 are connected to form a spherical cabin body 1, including: a main shaft 2, the main shaft 2 has a clamping portion 201 on one side, and a threaded portion 202 on the other side, the clamping portion 201 is used to be installed on the chuck, the clamping portion rotates with the chuck, the main shaft 2 is used to pass through the spherical cabin body 1, and the main shaft 2 is used to pass through the first through hole 1011 and the second through hole 1021; a pad 3, which is sleeved outside the threaded portion 202 and is used to abut against one side of the spherical cabin body 1, and the other side of the spherical cabin body 1 abuts against one end of the clamping portion 201; a locking nut 4, which is threadedly arranged on the threaded portion 202, and the locking nut 4 abuts against one side of the pad 3. The main shaft 2 further has a centering truncated cone 203 , which is located beside the clamping portion 201 . The centering truncated cone 203 is used for being coaxially plugged with the first through hole 1011 .

[0036] When using, Figure 1 As shown, the spherical cabin 1 formed by butting two hemispherical cabins 1 can be welded by equatorial seam welding. The first cabin 101 and the second cabin 102 processed by two drilling machines are butted, the main shaft 2 passes through the first through hole 1011 and the second through hole 1021, and is coaxially arranged with the central axis position of the spherical cabin 1. The pad 3 abuts against the outside of the second cabin 102, and then is locked by the locking nut 4, and the spherical cabin 1 is clamped between the pad 3 and the clamping part 201, so as to realize the butt fixation of the two hemispherical cabins 1 and the synchronous rotation connection with the main shaft 2. The clamping part 201 can be mounted on a three-jaw chuck and driven to rotate by the three-jaw chuck. It can be determined whether the side where the locking nut 4 is located needs to be supported by rotation according to the size requirements of the spherical cabin 1. When the diameter of the spherical cabin 1 is large, the side where the locking nut 4 is located is supported by rotation, which can realize more stable rotation. The rotation support mechanism can also be a three-rotation chuck, and the three-jaw chucks on both sides can rotate synchronously.

[0037] After the first cabin 101 and the second cabin 102 are docked, the main shaft 2 can pass through the central axis position, and then the locking nut 4 is locked, so that the coaxial rotation of the spherical cabin 1 and the main shaft 2 is realized. The centering cone 203 can also be sleeved in the first through hole 1011 to eliminate manual operation errors and more accurately realize the coaxial connection between the main shaft 2 and the spherical cabin 1. If there is an internal thread in the first through hole 1011, the centering cone 203 can have an external thread that matches it. The end surface of the first cabin 101 and the second cabin 102 can be an internal and external nested structure, which can ensure good concentricity during docking and avoid misalignment. On the side where the locking nut 4 is located, there is no need for a structure similar to the centering cone 203 for coaxial centering, and clamping and positioning are sufficient. The centering cone can be an integral structure with the main shaft 2, which is only for one type of spherical water tank, or it can be a mounting part, which is sleeved and fixed on the main shaft 2, so as to adapt to different spherical water tanks.

[0038] Furthermore, it also includes: a sleeve 5, which is sleeved on the backing plate 3, and a locking nut 4 is located in the sleeve 5, and the sleeve 5 is rotatably arranged.

[0039] When in use, the backing plate 3 is used as an intermediate piece between the locking nut 4 and one side of the spherical cabin body 1. Through the rotation setting of the sleeve 5, when the backing plate 3 and the spherical cabin body 1 rotate synchronously, the sleeve 5 can be supported and limited by the rotation support mechanism to realize the rotation of the sleeve 5, or the sleeve 5 is suspended and rotated, for example, the sleeve 5 is clamped by a three-jaw chuck. The rotation support structure can also be a bracket, the sleeve 5 is rotatably connected to the bracket, and the main shaft 2 drives the sleeve 5 to rotate.

[0040] A bolt seat may be provided on one side of the backing plate 3, and the locking nut 4 may be located in the bolt seat. By limiting the rotation of the sleeve 5, the sleeve 5 and the main shaft 2 rotate relative to each other, and the locking nut 4 can be tightened and loosened.

[0041] Furthermore, it also includes: a turntable 6, which is detachably arranged on the main shaft 2 and rotates with the main shaft 2, and the upper end of the turntable 6 is used to place the first cabin 101 or the second cabin 102; a pressure plate 7, which is movably arranged relative to the turntable 6 and is used to abut against the outside of the first cabin 101 or the second cabin 102, and the pressure plate 7 has a positioning hole 701 in the middle, and the positioning hole 701 is sleeved on the outside of the first cabin 101 or the second cabin 102.

[0042] When using, Figure 2 As shown, the turntable 6 can be detachably arranged on the main shaft 2. When the turntable 6 is installed, the hemispherical cabin body can be machined and the local added parts can be welded. When the turntable 6 is removed, the equatorial weld of the spherical cabin body 1 can be welded, providing an overall solution for the spherical water tank processing and welding tooling.

[0043] The end face of the first cabin body 101 or the second cabin body 102 is fitted with the upper end of the turntable 6 and buckled on the turntable 6. Then, the pressure plate 7 can be moved down to abut against the outer side of the cabin body to fix the first cabin body 101 or the second cabin body 102 on the turntable 6 and rotate with the turntable 6 so that the processing position on the spherical surface can be transferred to the processing end of the processing equipment. Then, additional parts such as flanges or channels can be added to the processed holes. At the same time, welding equipment can be used to weld the additional parts to the cabin body. The welding angle during welding can be adjusted by rotating the main shaft 2, which is convenient for welding relative to the welding equipment.

[0044] The structure of the positioning hole 701 can be a vertical through hole or a tapered through hole or a hole-shaped structure that fits the spherical surface, which can better fit and abut the spherical surface to achieve stable compression and positioning.

[0045] Furthermore, both sides of the turntable 6 have plug-in holes 601 ; the clamping portion 201 has a first plug-in connector 2011 , which is used to be plug-in connected to one plug-in hole 601 ; the outside of the sleeve 5 has a second plug-in connector 501 , which is used to be plug-in connected to another plug-in hole 601 .

[0046] When in use, the turntable 6 is detachably connected to the main shaft 2 through the plug-in hole 601. The first connector 2011 and the second connector 501 can both be an "I" structure, which can quickly realize sleeve plug-in and can also perform circumferential rotation transmission. The support for the turntable 6 is also strong. The plug-in hole 601 can be matched with the connector structure.

[0047] Furthermore, the clamping portion 201 also has a first baffle 2012 , which is used to abut against one side of the turntable 6 ; the sleeve 5 also has a second baffle 502 outside, which is used to abut against the other side of the turntable 6 .

[0048] When in use, the first baffle 2012 and the second baffle 502 are used to clamp and fix the turntable 6 from both sides, so that the turntable 6 and the main shaft 2 are stably connected and rotate synchronously. When installing the turntable 6, remove the locking nut 4 and the pad 3, then insert the turntable 6 on the main shaft 2, and insert the plug hole 601 on one side into the first plug-in piece 2011, and the right side of the turntable 6 abuts against the first baffle 2012, then install the pad 3 and the locking nut 4 on the other side, and the second baffle 502 abuts against the left side of the turntable 6, and tighten the locking nut 4 to fix the turntable 6 and the main shaft 2.

[0049] Furthermore, the pressure plate 7 also has a plurality of guide holes 702; it also includes: a plurality of guide rods 8, which are distributed along a rectangular array on the upper end of the turntable 6, and the guide rods 8 are slidably sleeved with the guide holes 702; a locking member 9 is slidably arranged on the guide rods 8 and abuts against the pressure plate 7. The end of the guide rod 8 has a clamping thread 801; the locking member 9 is a clamping nut, and the clamping thread 801 is threadedly connected with the clamping nut.

[0050] When in use, after the first cabin 101 or the second cabin 102 is placed on the turntable 6, the pressure plate 7 is installed along the guide rod 8 to press down the first cabin 101 or the second cabin 102, and the pressure plate 7 is locked by the locking member 9 to fix the first cabin 101 or the second cabin 102. The locking member 9 can be a clamp structure or the like.

[0051] The locking member 9 can be a clamping nut, which is threadedly connected to the clamping thread 801 and is located at the upper end of the pressure plate 7, so as to clamp the pressure plate 7.
