Description

Technical Field

[0001] The invention relates to the technical field of clamping and positioning tooling, and in particular to an auxiliary clamping device used for welding a diesel generator set base. Background Art

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It consists of a power system, a control system, a silencer system, a shock absorption system, and an exhaust system.

[0003] In principle, the generator set is driven by a turbine, steam turbine, diesel engine or other power machinery, which converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy and outputs it to electrical equipment for use.

[0004] Specifically speaking of the structure of the diesel generator set, it is mainly assembled from components such as a diesel engine, a generator, a base, an electric control box, a water tank, etc. Among them, the generator set base is a supporting component, which is mainly used as an assembly base for the main components such as the diesel engine, the generator, the electric control box, the water tank, etc. During the manufacturing process, the generator set base is mainly composed of several steel frames that are cut and welded. In terms of the composition of welded components, the generator set base includes cross beams of different lengths, longitudinal beams and a U-shaped fixed support seat.

[0005] In the specific welding work, it is necessary to first classify and clamp different welding parts, and then butt-weld the precisely positioned welding parts in sequence. However, since there are many welding components of the diesel generator base, the shapes and sizes of each welding component cannot be unified. As a result, when the existing clamping tooling is used to weld and clamp the above-mentioned crossbeams, longitudinal beams and fixed support seats, the following problems will inevitably arise:

[0006] 1. The clamping method is single and difficult to adapt to the clamping and positioning of different welding parts. Specifically, the crossbeam, longitudinal beam and fixed support seat have significant differences in length and shape, and different welding parts need to be placed in different positions during the welding process. The existing single clamping method is not suitable for the clamping of welding parts of different shapes, and it is difficult to transfer and position the welding parts after clamping.

[0007] 2. There is a clamping interference problem between different welding clamping mechanisms, resulting in poor coordination of welding clamping, which requires the welding connection between components to be carried out in multiple steps, greatly reducing the welding efficiency.

[0008] 3. The position state of each welding component after clamping and loading is usually different from the welding position state, and secondary adjustment is required to align the welding components. However, the existing clamping tooling has poor adjustability and is inconvenient to use.

[0009] 4. Due to the limitation of the clamping method, double-sided welding is inconvenient. Specifically, since the main function of the generator base is to support the main components such as the generator and diesel engine, and the load it bears is relatively large, double-sided welding is often required during the welding of components on the generator base to increase the connection strength. However, the existing clamping tooling generally adopts a horizontal clamping positioning method, which requires flipping to achieve welding and changing sides, which is cumbersome.

[0010] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention
