Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding tooling technology, and in particular to an adjustable rotating tooling for welding pressure vessels of different pipe diameters. Background Technology
[0002] In modern industrial production, pressure vessels are indispensable and important equipment due to their wide application in many industries such as chemical, petroleum, and power. The manufacturing quality of pressure vessels is directly related to the safety and reliability of the equipment. Therefore, high-quality welding processes are particularly important for pressure vessels.
[0003] Traditional pressure vessel welding methods typically rely on fixed-position tooling fixtures, such as two sets of rotatable support wheels at a fixed distance. The support wheels support the pressure vessel and drive it, enabling the pressure vessel to rotate, thus facilitating circumferential welding.
[0004] However, this method has many limitations. It can only be adapted to pressure vessels of specific sizes. Different tooling fixtures are required for vessels of different diameters, which not only increases costs but also reduces production efficiency. In addition, fixed welding fixtures often cannot ensure the stability and accuracy of the vessel throughout the welding process when dealing with large or heavy pressure vessels, which can lead to a decline in welding quality and even safety hazards. Utility Model Content
[0005] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.
[0006] To achieve the above objectives, the first aspect of this utility model proposes an adjustable rotating fixture for welding pressure vessels of different pipe diameters, comprising: a base plate, a rotating device, a support wheel assembly, and a clamping device. The base plate has two rotating devices with adjustable angles arranged opposite each other. Each rotating device is equipped with a support wheel assembly, and one of the support wheel assemblies is connected to the output end of a first drive motor. Each rotating device is equipped with a clamping device, which includes a rotating arm, a clamping wheel, and a second drive motor. The rotating arm is rotatably mounted on the rotating device, and the clamping wheel is rotatably mounted at the end of the rotating arm. The output end of the second drive motor is connected to the rotating arm. The ends of two pressure vessels to be welded are arranged opposite each other and located between the two rotating devices, with the lower part of the pressure vessel abutting against the support wheel assembly and the upper part of the pressure vessel abutting against the clamping wheel.
[0007] In addition, the adjustable rotary tooling for welding pressure vessels of different pipe diameters proposed above according to this utility model may also have the following additional technical features:
[0008] As a further description of the above technical solution: each of the support wheel sets includes at least two spaced support wheels, and the multiple support wheels are connected by a first connecting shaft; wherein, when the ends to be welded of the two pressure vessels are arranged opposite each other between the two rotating devices, the ends to be welded are located between the spaced support wheels.
[0009] As a further description of the above technical solution: each set of the clamping device has at least two sets of rotating arms spaced apart and connected by a second connecting shaft; wherein, when the ends to be welded of the two pressure vessels are arranged opposite each other between the two rotating devices, the ends to be welded are located between the spaced rotating arms.
[0010] As a further description of the above technical solution: the rotating device includes a rotating frame and a telescopic rod, wherein the bottom of the rotating frame is pivotally connected to the base plate; one end of the telescopic rod is pivotally connected to the base plate, and the other end is pivotally connected to the back of the rotating frame.
[0011] As a further description of the above technical solution: the telescopic rod is a hydraulic rod or an electric rod, and is synchronously connected to the controller respectively.
[0012] As a further description of the above technical solution: a slot is provided at the center of the rotating frame to expand the welding space.
[0013] As a further description of the above technical solution: both the support wheel and the pressure wheel have an anti-slip layer on their outer rings.
[0014] The adjustable rotating tooling for welding pressure vessels of different pipe diameters according to this utility model can quickly adjust the distance between the support wheels through the cooperation of the adjustable angle rotating device and the support wheel set, thereby adapting to pressure vessels of different diameters without the need for frequent changes of tooling fixtures, greatly improving the versatility and flexibility of the tooling; in addition, the clamping device can apply a stable clamping force above the pressure vessel, ensuring welding stability even when the pressure vessel rotates with the support wheel set, effectively avoiding welding quality problems caused by container shaking.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] The following description, in conjunction with the accompanying drawings, describes an adjustable rotating tooling for welding pressure vessels of different pipe diameters according to an embodiment of the present invention.
[0026] like Figures 1 to 4 As shown, the adjustable rotating tooling for welding pressure vessels of different pipe diameters according to this utility model embodiment may include a base plate 100, a rotating device 200, a support wheel set 300, and a clamping device 400.
[0027] The base plate 100 has adjustable rotating devices 200 on both sides, and each rotating device 200 is equipped with a support wheel set 300, and one of the support wheel sets 300 is connected to the output end of the first drive motor 301.
[0028] Each rotating device 200 is equipped with a clamping device 400, which includes a rotating arm 410, a clamping wheel 420, and a second drive motor 430.
[0029] The rotating arm 410 is rotatably mounted on the rotating device 200, the pressure wheel 420 is rotatably mounted at the end of the rotating arm 410, and the output end of the second drive motor 430 is connected to the rotating arm 410.
[0030] The two pressure vessels 500 are positioned opposite each other and between the two rotating devices 200. The lower part of the pressure vessel 500 abuts against the support wheel assembly 300, and the upper part of the pressure vessel 500 abuts against the clamping wheel 420.
[0031] Specifically, when relevant personnel are performing welding operations on the pressure vessel 500, they can place the pressure vessel 500 to be welded between the two rotating devices 200 by hoisting or lifting. Before placing the pressure vessel 500, the relevant personnel can adjust the rotation angle of the rotating device 200 so that the two support wheel sets 300 can support the lower part of the pressure vessel 500.
[0032] After the pressure vessel 500 is placed on the rotating device 200 and the gap between the two pressure vessels 500 to be welded is adjusted, the relevant personnel start the second drive motor 430, adjust the position of the rotating arm 410, so that the clamping wheel 420 abuts against the upper part of the pressure vessel 500 and applies appropriate clamping force.
[0033] Then, the relevant personnel start the first drive motor 301, which drives the support wheel assembly 300 to rotate, so that the two pressure vessels 500 rotate synchronously. During rotation, the support wheel assembly 300 is always in contact with the lower part of the pressure vessel 500, while the clamping wheel 420 is always in contact with the upper part of the pressure vessel 500. This makes the pressure vessel 500 more stable when it rotates, which is convenient for the relevant personnel to carry out welding operations.
[0034] In one embodiment of the present invention, each support wheel assembly 300 includes at least two spaced support wheels, and the multiple support wheels are connected to each other via a first connecting shaft 302.
[0035] When the ends of the two pressure vessels 500 to be welded are positioned opposite each other between the two rotating devices 200, the ends to be welded are located between the spaced support wheels.
[0036] To clearly illustrate the previous embodiment, in one embodiment of this utility model, the rotating arms 410 of each set of pressing devices 400 are at least two sets spaced apart and connected by a second connecting shaft 401.
[0037] When the ends of the two pressure vessels 500 to be welded are positioned opposite each other between the two rotating devices 200, the ends to be welded are located between the spaced rotating arms 410.
[0038] It should be noted that by placing the ends of the two pressure vessels 500 to be welded between the two support wheels and the two rotating arms 410, the ease of welding for the workers can be ensured.
[0039] In one embodiment of the present invention, the rotating device 200 includes a rotating frame 210 and a telescopic rod 220.
[0040] The bottom of the rotating frame 210 is pivotally connected to the base plate 100, one end of the telescopic rod 220 is pivotally connected to the base plate 100, and the other end is pivotally connected to the back of the rotating frame 210.
[0041] It should be noted that when relevant personnel adjust the rotation angle of the rotating device 200, the telescopic rod 220 can be activated to extend or shorten, thereby driving the rotating frame 210 to rotate, causing the support wheel set 300 on the rotating frame 210 to rotate accordingly. This allows the support wheel sets 300 on the two rotating devices 200 to move closer or further apart to accommodate pressure vessels 500 of different sizes.
[0042] As one possibility, the telescopic rod 220 is a hydraulic rod or an electric rod, and is synchronously connected to the controller. Relevant personnel can use the controller to synchronously control the telescopic rods 220 on the two rotating devices 200, so that the two telescopic rods 220 move closer to each other or further apart.
[0043] In addition, to improve the stability of the pressure vessel 500 as it rotates, the outer rings of the support wheel and the clamping wheel 420 are equipped with anti-slip layers to increase friction and prevent the pressure vessel 500 from slipping during rotation.
[0044] In one embodiment of this utility model, such as Figure 5 As shown, a slot 201 is provided at the center of the rotating frame 210 to expand the welding space. Relevant personnel can perform welding operations at the slot 201, avoiding the need for operations above, and further reducing the welding convenience for relevant personnel.
[0045] In summary, the adjustable rotating tooling for welding pressure vessels of different pipe diameters according to the embodiments of this utility model, through the cooperation of the adjustable-angle rotating device 200 and the support wheel set 300, can quickly adjust the distance between the support wheels, thereby adapting to pressure vessels 500 of different diameters. This eliminates the need for frequent changes to tooling fixtures, greatly improving the versatility and flexibility of the tooling. Furthermore, the clamping device 400 can apply a stable clamping force above the pressure vessel 500, ensuring welding stability even as the pressure vessel rotates with the support wheel set 300, effectively avoiding welding quality problems caused by container shaking.
[0046] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
