Description

Technical Field

[0001] This utility model relates to the field of horizontal pressure vessel technology, and more specifically, to a saddle welding anti-deformation tooling. Background Technology

[0002] In the manufacturing process of horizontal pressure vessels, the saddle is an essential component. During the welding of the saddle base plate and the web stiffeners, the two saddle base plates are conventionally spot-welded together. If the base plate is thin and there are many stiffeners, poor welding control can easily lead to deformation, requiring reshaping, which is time-consuming and labor-intensive. Moreover, the spot welded areas need to be manually ground and removed afterward, which is also time-consuming. In addition, some saddle base plates have high flatness requirements that cannot be met by reshaping and need to be remade, affecting production efficiency.

[0003] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a saddle welding anti-deformation tooling to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A saddle welding anti-deformation fixture includes a saddle body, a first processing component is provided at one end of the saddle body, and second processing components are provided on both sides of the first processing component. The first processing component includes a fixture plate, which is located at the bottom end of the saddle body. The fixture plate has a slot, and a bolt is provided inside the slot. A limit block is threaded onto the bolt, and the limit block is located at the upper end of the fixture plate.

[0007] Furthermore, to better ensure the connection effect, a fixing clamp and a hexagonal nut are connected to the bolt, with the fixing clamp positioned above the limiting block and the hexagonal nut positioned above the fixing clamp.

[0008] Furthermore, to better ensure the connection effect, both the limiting block and the hexagonal nut are adapted to the bolt.

[0009] Furthermore, to better ensure the adjustment effect, the second processing component includes a mounting plate, which is symmetrically fixed on both sides of the tooling plate. The tooling plate is symmetrically provided with adjustment grooves, and one side of the mounting plate is connected to a first bidirectional screw via a fixing seat.

[0010] Furthermore, to better ensure the limiting effect, an adjusting seat is threadedly connected to the first bidirectional screw, and an adjusting screw is threadedly connected to the adjusting seat. One end of the adjusting screw passes through the adjusting groove and is provided with a limiting seat.

[0011] Furthermore, in order to better ensure the limiting effect, the limiting seat is provided with symmetrical movable grooves on one side, and a second bidirectional screw and a guide rod are provided on one side of the limiting seat. One end of the guide rod and the second bidirectional screw extends to the inner wall of the movable groove.

[0012] Furthermore, in order to better ensure the limiting effect at multiple positions, a limiting plate is connected to the second bidirectional screw and the guide rod, and the limiting plate is in contact with the saddle body.

[0013] The beneficial effects of this utility model are as follows: By setting the first processing component, the saddle body can be accurately positioned and rigidly fixed, making tooling manufacturing simpler and practical use more convenient. It also allows for the adjustment and reuse of saddle bodies of different specifications as needed. Moreover, the original process of spot welding and grinding of the two saddle base plates is eliminated by simply tightening bolts and nuts, which truly improves product manufacturing efficiency and product quality. Secondly, the second processing component uses a two-way screw and an adjusting screw to work together, which can flexibly adapt to saddle bodies of different sizes and achieve multi-directional fine adjustment, ensuring the flatness and assembly accuracy of the saddle before welding, meeting high flatness standards, thereby reducing manual shaping and grinding processes, significantly shortening the production cycle, reducing rework rate and material waste, and improving overall production efficiency.

[0023] Example 1:

[0024] like Figures 1-5 As shown, a saddle welding anti-deformation tooling according to an embodiment of the present utility model includes a saddle body 1, which is composed of a web, stiffening plates, and a bottom plate. A first processing component 2 is provided at one end of the saddle body 1 to solve the problem of welding deformation. Second processing components 3 are provided on both sides of the first processing component 2 to further ensure the fixing effect.

[0025] The first processing component 2 includes a tooling plate 201, which is located at the bottom of the saddle body 1. The tooling plate 201 has a slot 202, and a bolt 203 is installed inside the slot 202. A limit block 204 is threaded onto the bolt 203. In actual use, the limit block 204 is not set to a fixed specification, but is set to various thicknesses to better ensure the limiting effect. The limit block 204 is located at the upper end of the tooling plate 201. A fixing clamp 205 and a hexagonal nut 206 are connected to the bolt 203. The fixing clamp 205 is located above the limit block 204, and the hexagonal nut 206 is located above the fixing clamp 205. Both the limit block 204 and the hexagonal nut 206 are adapted to the bolt 203.

[0026] Example 2:

[0027] like Figures 1-5 As shown, according to an embodiment of the present invention, a saddle welding anti-deformation fixture includes a second processing component 3 comprising a mounting plate 301. The mounting plate 301 is symmetrically fixed on both sides of a fixture plate 201. Adjustment grooves 4 are symmetrically provided on the fixture plate 201. A first bidirectional screw 302 is connected to one side of the mounting plate 301 via a fixed seat. An adjustment seat 303 is threaded onto the first bidirectional screw 302. An adjustment screw 304 is threaded onto the adjustment seat 303. One end of the adjustment screw 304 passes through the adjustment groove 4 and is provided with a limiting seat 305. A movable groove 5 is symmetrically provided on one side of the limiting seat 305. A second bidirectional screw 306 and a guide rod 307 are provided on one side of the limiting seat 305. One end of the guide rod 307 and the second bidirectional screw 306 extends to the inner wall of the movable groove 5. A limiting plate 308 is connected to the second bidirectional screw 306 and the guide rod 307. The limiting plate 308 is made of rubber and is in contact with the saddle body 1.

[0028] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0029] In summary, using the above-mentioned technical solution of this utility model, the base plate of the saddle body 1 is first assembled, the position of the base plate of the saddle body 1 is adjusted as needed, bolts 203 are passed through the slots 202 of the tooling plate 201, then limit blocks 204 of the same thickness are selected according to the thickness of the base plate of the saddle body 1 and screwed onto the bolts 203, then the fixing clamp 205 is installed, and finally the hexagonal nuts 206 are used to tighten them, so that the base plate of the saddle body 1 is fixed on the tooling plate 201. Then the web plate and stiffening plate of the saddle body 1 are welded. By fixing the base plate of the saddle body 1, deformation at the welding position is prevented. After the welding is completed and cooled, the plates are removed, and the adjustment on both sides is driven by the first bidirectional screw 302. The joint seat 303 moves synchronously in the opposite direction. The adjusting screw 304 pushes the limiting seat 305 to move laterally along the adjusting groove 4. This bidirectional symmetrical adjusting mechanism can precisely control the distance between the two sets of limiting units, so that the longitudinal central axis of the saddle body 1 is perpendicular to the tooling plate 201, forming a basic positioning reference. The limiting plate 308 forms a compound kinematic pair with the guide rod 307 through the second bidirectional screw 306. When the second bidirectional screw 306 is rotated, the two sets of limiting plates 308 move symmetrically radially along the movable groove 5. The guide rod 307 provides linear motion constraint to ensure that the clamping surface always keeps parallel contact with the outer contour of the saddle body 1, forming a three-point ring clamping structure, so that the saddle body 1 is subjected to uniform force in the circumferential direction.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
