Description

Technical Field

[0001] This utility model relates to the field of reaction vessel processing technology, specifically to an automatic welding limiting tooling for reaction vessel processing. Background Technology

[0002] A reaction vessel is a container for materials to undergo physical or chemical reactions. Through structural design and parameter configuration of the container, the heating, evaporation, cooling and low-to-high-speed mixing functions required by the process can be achieved. The reaction vessel body is widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical and food industries.

[0003] When welding existing reaction vessel tanks, it is necessary to first prepare the upper and lower tanks of the chemical reaction vessel to be welded, check the quality of the materials, and ensure that they meet the design requirements and relevant standards. Use appropriate tools and methods to clean the surface of the welding area. Then, use clamps, supports and other auxiliary equipment to correctly position and fix the upper and lower tanks. Perform the welding operation according to the specific welding method. After the welding is completed, inspect and repair the weld.

[0004] In the reactor welding process, the reactor is placed on an automatic welding drum for welding. However, due to the interaction of various complex factors such as the workpiece's own center of gravity deviation, the slight unevenness of the drum surface, or the thermal stress generated during the welding process, the workpiece will inevitably be misaligned, which will lead to serious weld seam displacement, reduce welding efficiency and greatly affect welding quality. To address this, an automatic welding limiting fixture for reactor processing is proposed. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic welding limiting tooling for processing reaction vessels, including a guide rail base frame;

[0007] A load-bearing module is movably mounted on the guide rail base frame. The load-bearing module includes a first support component and a second support component arranged opposite to each other on the left and right. The first support component and the second support component have the same structure.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] An automatic welding limit fixture for reactor processing, such as Figure 1-4As shown, it includes a guide rail base frame 100;

[0030] The support module 200 is movably mounted on the guide rail base 100. The support module 200 includes a first support component 300 and a second support component 400 arranged opposite each other. The first support component 300 and the second support component 400 have the same structure. The first support component 300 can move left and right relative to the second support component 400 on the guide rail base 100 through the support module 200.

[0031] The first support assembly 300 includes a base frame 310, a second roller 320 and a third roller 330. The second roller 320 and the third roller 330 are arranged opposite each other on the base frame 310, and the second roller 320 and the third roller 330 have the same structure.

[0032] By placing the reactor between the second roller 320 and the third roller 330, the second roller 320 and the third roller 330 support the reactor and can adapt to slight positional changes of the workpiece during the welding process through the rolling of the second roller 320 and the third roller 330, thereby maintaining the relative stability of the workpiece and effectively preventing the displacement problem caused by factors such as the workpiece's own center of gravity deviation, uneven roller surface, or welding thermal stress. The design of this limiting tooling effectively solves the weld quality problem caused by displacement of the reactor during the welding process in the prior art, and improves welding efficiency and workpiece quality.

[0033] When welding the two cylinders together, the second roller 320 and the third roller 330 are made to fit tightly against the outer wall of the reactor. Then, the welding equipment is started to weld the two sets of cylinders. At the same time, the second roller 320 and the third roller 330 can roll with the rotation of the reactor. Through the tight frictional coupling between the two cylinders, the workpiece is forced to rotate smoothly in a very precise and fixed position, thereby maintaining stable support for the reactor, fundamentally eliminating displacement, ensuring the straightness and uniformity of the weld, and laying a solid foundation for high-quality welding results.

[0034] Please refer to this carefully. Figure 2 The first support assembly 300 also includes a transmission assembly 600, which is located inside the base frame 310 and is connected to the second roller 320 and the third roller 330.

[0035] By rotating the transmission assembly 600, the second roller 320 and the third roller 330 can move relative to each other, effectively adjusting the spacing according to the diameter of the reactor, thus further enhancing the applicability of the device.

[0036] Please refer to this carefully. Figures 1 to 4An auxiliary frame 500 is located on the left side of the first support assembly 300. The auxiliary frame 500 is equipped with a first roller 530 facing the inclined surface of the first support assembly 300. The auxiliary frame 500 includes a cross frame 510 and a tripod 520. One end of the cross frame 510 is connected to the first support assembly 300, and the upper end of the cross frame 510 is connected to the tripod 520. The first roller 530 is installed on the side of the tripod 520 facing the first support assembly 300. The tripod 520 has a right-angled triangular structure, and the inclined surface of the tripod 520 faces the first support assembly 300. The tripod 520 is also provided with several mounting holes 540 from top to bottom, which are suitable for mounting the first roller 530.

[0037] When welding is required between the end cap and the straight cylinder, the first roller 530 is precisely fixed to the inclined side of the tripod 520. Since the end cap is elliptical and its curvature is relatively complex, the height of the first roller 530 on the inclined surface of the tripod 520 can be adjusted through the mounting hole 540 so that the first roller 530 can fit tightly against the surface of the end cap. During the welding process, the first roller 530 constrains the rotation trajectory of the end cap and avoids displacement due to rotation, thereby ensuring that the welding between the end cap and the straight cylinder can be carried out accurately and without error, significantly improving the accuracy and reliability of the welding.

[0038] In use, the reactor is supported by the second roller 320 and the third roller 330. During welding, the rolling of the second roller 320 and the third roller 330 adapts to minor positional changes in the workpiece, thus maintaining relative stability and effectively preventing displacement caused by factors such as workpiece center of gravity deviation, uneven roller surface, or welding thermal stress. When welding straight cylinders together, the second roller 320 and the third roller 330 are brought into close contact with the outer wall of the reactor before the welding equipment is started to weld the two sets of cylinders. Simultaneously, the second roller 320... The first roller 530 and the third roller 330 can roll along with the rotation of the reactor. Through the tight frictional coupling between the two straight cylinders, the workpiece is forced to rotate smoothly in a very precise and fixed position, thereby maintaining stable support for the reactor. When welding operations are required on the head and the straight cylinder, the first roller 530 constrains the rotation trajectory of the head to avoid displacement due to rotation, thereby ensuring that the welding between the head and the straight cylinder can be carried out accurately and without error, significantly improving the accuracy and reliability of welding. All parts not involved in this device are the same as or can be implemented using existing technologies.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
