Description

Technical Field

[0001] The utility model relates to the field of processing of internal parts of a final polymerization kettle, in particular to an auxiliary tool for processing the internal parts of a final polymerization kettle. Background Art

[0002] In industrial production, kettle containers are often encountered. Due to the large size of the internal parts such as the kettle body and the squirrel cage in the design and manufacturing, many problems often arise during the on-site processing of the kettle parts such as the squirrel cage and the bearing seat. Therefore, in the process of manufacturing the kettle internals, it is very necessary to manufacture an auxiliary tooling in the manufacturing plant. If the squirrel cage is large, processing may consume a lot of manpower and time, and many problems will also be found. These problems should be solved before processing.

[0003] After the kettle body is manufactured, the kettle body manufacturer has no tools to support the squirrel cage. If the squirrel cage is processed directly, the squirrel cage processing deviation will be too large, the time will be prolonged, the difficulty will increase, and the distance between the two squirrel cages will not match after installation. Since there is no bearing seat processing tooling, the concentricity deviation is too large, the height is inconsistent, and the shaft cannot be installed. These problems are quite serious and affect the equipment.

[0004] Therefore, it is necessary to invent an auxiliary tooling for processing the internal parts of a final polymerization reactor. Utility Model Content

[0005] To this end, the utility model provides an auxiliary tooling for processing the internal parts of a final polymerization reactor to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary tooling for processing the internal parts of a final polymerization reactor, comprising:

[0007] A first tooling assembly, used to assist in processing the squirrel cage;

[0008] The second tooling assembly is used for assisting in processing the bearing seat, and the second tooling assembly is located directly above the first working assembly.

[0009] Preferably, the first tooling assembly includes a plurality of base plate supports 1, a bearing base plate 2 is fixed on the top of the plurality of base plate supports 1, the bearing base plate 2 is configured as an H-shaped steel support, two groups of columns 3 are symmetrically fixed at both ends of the top of the bearing base plate 2, each group of the columns 3 is a plurality of columns 3, and a bracing beam 4 is fixed between the plurality of columns 3 in the same group.

[0010] Preferably, a top plate 5 is horizontally fixed to the top of each group of the uprights 3 , a reinforcing rib plate 6 is welded to the top of the top plate 5 , and a pad 7 is welded to the top of the opposite end of the top plate 5 .

[0011] Preferably, the second tooling assembly comprises a bottom plate 8 , and a lower clamp 9 is welded on the top of the bottom plate 8 .

[0012] Preferably, the second fixture assembly further comprises an upper clamp 11 , and clamping flanges 10 are symmetrically welded to opposite ends of the upper clamp 11 and the lower clamp 9 .

[0013] The beneficial effect of the utility model is that through the use of the first tooling assembly and the second tooling assembly, the processing of the squirrel cage and the bearing seat of the final polymerization kettle internal parts can better meet the requirements, and there is no need to dismantle and reprocess due to the processing exceeding the allowable deviation, which not only saves time, but also reduces the working procedures and further reduces the cumulative error.

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Please refer to the attached Figure 1-4 The utility model provides an auxiliary tooling for processing the internal parts of a final polymerization reactor, comprising a first tooling component for assisting the processing of a squirrel cage, and a second tooling component for assisting the processing of a bearing seat, wherein the second tooling component is located directly above the first working component;

[0023] The first tooling assembly includes a plurality of bottom plate supports 1, a bearing bottom plate 2 is fixed on the top of the plurality of bottom plate supports 1, the bearing bottom plate 2 is set as an H-shaped steel support, two groups of columns 3 are symmetrically fixed at both ends of the top of the bearing bottom plate 2, and each group of columns 3 has a plurality of columns 3, and a tensioning crossbeam 4 is fixed between the plurality of columns 3 in the same group, and the tensioning crossbeam 4 can effectively increase the stability between each group of columns 3, a top plate 5 is horizontally fixed on the top of each group of columns 3, a reinforcing rib plate 6 is welded on the top of the top plate 5, and the reinforcing rib plate 6 can play a role in increasing the stability of the top plate 5, and a pad 7 is welded on the top of the opposite end of the top plate 5. Specifically, the user can place the squirrel cage of the final polymerization kettle internals on the pad 7 for processing, thereby effectively solving the problem that if the squirrel cage is directly processed due to the lack of a tool to support the squirrel cage, the squirrel cage processing deviation will be too large, the time will be prolonged, the difficulty will be increased, and the distance between the two squirrel cages after installation will not match;

It should be noted that the clamping flanges 10 welded at both ends of the upper clamp 11 and the clamping flanges 10 welded at both ends of the lower clamp 9 are fixed by bolts (not shown in the figure). Specifically, the user can put the bearing seat of the internal parts of the final polymerization kettle between the upper clamp 11 and the lower clamp 9, and then fix the upper clamp 11 and the clamping flanges 10 on the lower clamp 9, so that the bearing seat is clamped and fixed between the upper clamp 11 and the lower clamp 9, which can effectively solve the problem of excessive concentricity deviation, inconsistent height, and inability to install the shaft due to the lack of bearing seat processing tooling.
