Description

Technical Field

[0001] This utility model relates to electrical equipment, specifically to equipment for processing reactors. Background Technology

[0002] A reactor consists of coils wound around an iron core, which is made up of several sets of silicon steel sheets connected together. Each set of silicon steel sheets is composed of stacked silicon steel sheets. Each set of silicon steel sheets is welded together, and several sets of silicon steel sheets are then welded together to form the iron core. The iron core is then welded to an external support frame of the reactor, ultimately forming the finished reactor. The reactor is installed in its working position using the external support frame. The weld points between the iron core and the external support frame are located at the top and bottom of the reactor. Using current technology, workers position the iron core on a fixture, weld the external support frame to the top of the iron core, then loosen the iron core, flip it over on the fixture so that the bottom of the iron core faces upwards, and then position the iron core again. Finally, the external support frame is welded to the bottom of the iron core. This process is inefficient. Utility Model Content

[0003] The technical problem solved by this utility model is that when workers weld external supports to the top and bottom of the reactor, they need to flip the reactor on a fixture for secondary clamping, which results in low work efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a reactor welding fixture, including a fixture body, the fixture body including a fixture base plate, a horizontal quick clamp set at the front end of the fixture base plate, and a vertical quick clamp set at the rear end of the fixture base plate. The fixture base plate is provided with a reactor positioning block, a reactor limiting block and a support positioning column. The vertical quick clamp is installed on the reactor limiting block. The middle part of the fixture base plate is hollowed out. The left side of the fixture base plate is hinged to the left side of the bottom substrate through a hinge shaft. The bottom substrate is fixed on the worktable.

[0005] According to the above technical solution, the bottom support of the reactor is positioned on the fixture body by the support positioning post, the reactor is positioned on the reactor positioning block of the fixture base plate, and is located between the horizontal quick clamp and the reactor limiting block. The top support of the reactor is positioned on the top of the reactor. Then, the horizontal quick clamp acts on the reactor, pressing the reactor tightly against the reactor limiting block. The vertical quick clamp acts on the reactor, pressing the top support onto the reactor, the reactor onto the bottom support, and the bottom support onto the fixture base plate. Next, the worker welds the top support to the reactor core. After completion, the fixture body is rotated around the hinge axis so that the bottom surface of the fixture base plate faces upwards. The worker then welds the connection between the bottom support and the reactor core through the hollow structure on the fixture base plate.

[0006] Compared to the secondary clamping in the prior art, this invention allows for the welding of the top and bottom supports of the reactor in a single clamping operation, which improves work efficiency.

[0007] The hinge shaft is welded to the left side of the bottom base plate, and a hinge lug is welded to the base plate of the fixture. The hinge lug mates with the hinge shaft.

[0008] A support block is fixed on the bottom base plate, supporting the bottom of the fixture base plate and creating a gap between the fixture base plate and the bottom base plate. This gap allows the worker to easily flip the fixture body.

[0009] A support frame is installed on the left side of the fixture base plate, which can support the fixture body after it has been flipped over on the worktable.

[0010] A pressure head is mounted on the vertical quick-release fixture; a flat push block is mounted on the horizontal quick-release fixture. The top of the flat push block has a bending structure, and the base plate of the fixture has a guide groove to guide the translation of the flat push block. While the flat push block horizontally presses against the reactor, the bending structure at its top can limit the top of the reactor, ensuring the reactor is stably positioned on the fixture body. Especially when the fixture body is flipped, the bending structure prevents the reactor from detaching from the flat push block.

[0011] The fixture base plate has a perforated structure with horizontal bars, which are fixed to the left and right sides of the perforated structure by bolts, with the bolt heads protruding upwards from the horizontal bars. The horizontal bars support the reactor, and the bolt heads limit the reactor's movement in the left and right directions. Attached Figure Description
