Description

Technical Field

[0001] The invention relates to the technical field of large power transformers, and in particular to a mother-and-child tooling and a method thereof for accelerating the assembly and manufacturing progress of a power transformer coupling pipe. Background Art

[0002] The cooler bracket of large power transformer is an important component of the transformer cooling system. It is a bracket that supports the fixed cooler and is also a pipeline connecting the cooler and the oil tank. It is connected to the oil tank through a fixed bracket. The cooler bracket is required in the assembly process of the connecting pipe and the fixed bracket.

[0003] In the current joint pipe assembly process, the cooler bracket is often not produced in time, and it is often necessary to stop work and wait for the bracket to arrive before assembly. This affects the progress of the joint pipe assembly, thereby extending the production cycle of the transformer oil tank and affecting the transformer delivery cycle.

[0004] Therefore, in view of the situation that the cooler bracket is not produced in time during the existing coupling assembly process, which affects the assembly progress, a parent-child tooling and method can be designed to speed up the assembly progress of the power transformer coupling. Through the parent-child tooling assembly method, it is ensured that the assembly of the coupling no longer needs to wait for the cooler bracket, thereby ensuring the production progress and meeting the assembly quality requirements of the product, thereby effectively shortening the assembly operation cycle. Summary of the invention

[0005] In order to overcome the problem that most of the joint pipe assembly production processes often need to stop work and wait for the arrival of the bracket before the assembly operation can be carried out, which affects the progress of the joint pipe assembly production and thus causes the transformer oil tank production cycle to be extended.

[0006] The technical solution of the present invention is:

[0008] Preferably, the cooler bracket or the sub-tooling frame is limited by setting a limit plate to ensure the consistency of the outer dimensions of the cooler bracket, the cooler bracket or the sub-tooling frame is fixed to the main tooling frame, the connecting pipe interface is used to clarify the connecting pipe welding position, the fixed bracket interface is used to clarify the fixed bracket welding position, the connecting pipe interface and the fixed bracket interface welding point are clarified by the positioning component, the disassembly and assembly component is used to flexibly disassemble the detachable plate, and the position of the cooler bracket or the sub-tooling frame is flexibly locked by the detachable plate, so that the cooler bracket or the sub-tooling frame can be easily detached from the main tooling frame after the welding operation is completed, and the sub-tooling frame is used to replace the cooler bracket to assemble and manufacture the connecting pipe, thereby avoiding the dependence of the connecting pipe assembly and manufacture on the cooler bracket, thereby ensuring that the assembly and manufacture of the connecting pipe no longer needs to wait for the cooler bracket, thereby ensuring the production progress, meeting the assembly quality requirements of the product, and effectively shortening the assembly operation cycle.

[0009] Preferably, multiple groups of connecting pipe interfaces are provided, multiple groups of fixed bracket interfaces are provided, and four groups of limiting plates are provided.

[0010] Preferably, three groups of connecting pipe interfaces are arranged on one side of the mother tooling frame, and four groups of fixed bracket interfaces are arranged on one side of the mother tooling frame.

[0011] Preferably, three groups of connecting pipe interfaces are provided on one side of the sub-tooling frame, and four groups of fixing bracket interfaces are provided on one side of the sub-tooling frame.

[0012] Preferably, the connecting pipe interface position on one side of the mother tooling frame corresponds to the connecting pipe interface position on one side of the child tooling frame, and the fixed bracket interface position on one side of the mother tooling frame corresponds to the fixed bracket interface position on one side of the child tooling frame.

[0015] The second aspect of the present invention provides a method for accelerating the assembly and production progress of the power transformer coupling pipe, including using the parent-child tooling as described above, accelerating the welding operation based on the parent-child tooling, thereby accelerating the assembly and production progress of the power transformer coupling pipe.

[0016] Beneficial effects of the present invention:

[0017] 1. When assembling the connecting pipe, the cooler bracket or the sub-tooling frame is limited by setting a limit plate to ensure the consistency of the outer dimensions of the cooler bracket, and the cooler bracket or the sub-tooling frame is fixed to the main tooling frame. The connecting pipe interface is used to clarify the connecting pipe assembly welding position, and the fixed bracket interface is used to clarify the fixed bracket assembly welding position. The cooler bracket or the sub-tooling frame is flexibly locked by the detachable plate, so that after the assembly welding operation is completed, the cooler bracket or the sub-tooling frame can be easily separated from the main tooling frame. The sub-tooling frame is used to replace the cooler bracket to assemble and manufacture the connecting pipe, avoiding the dependence of the connecting pipe assembly and production on the cooler bracket, so as to solve the problem that in most connecting pipe assembly and production processes, the cooler bracket is often not produced in time, and it is often necessary to stop work and wait for the bracket to arrive before assembly, which affects the progress of connecting pipe assembly and production, thereby extending the production cycle of the transformer oil tank, and effectively shortening the assembly operation cycle.
