Description

Technical Field

[0001] This utility model relates to a processing device for a generator, and more particularly to a welding and positioning fixture for a semi-direct drive wind turbine housing component. Background Technology

[0002] A semi-direct-drive wind turbine (semi-direct-drive wind power generator) is a type of wind power generation equipment. Compared to traditional wind power generators, it eliminates the gearbox in its design, directly transmitting the rotational power of the wind turbine to the generator. This structure simplifies the complexity of traditional wind turbines, reduces maintenance costs, and improves operational reliability. The semi-direct-drive wind turbine falls between direct-drive and traditional wind turbines with gearboxes; it typically uses a small gear reducer to achieve speed matching between the wind turbine and the generator.

[0003] When processing the casing of a semi-direct drive wind turbine, a welding process is required. Due to the large size of the casing, it is difficult to fix it when placed on the ground. Therefore, manual welding is inefficient, time-consuming, and the weld consistency is poor, which will have a certain impact on delivery time, cost, and quality. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a welding positioning fixture for a semi-direct drive wind turbine housing component, including a base plate and a side plate. The side plate is fixedly mounted on the base plate. The base plate and the side plate cooperate with each other to form a fixture assembly for fixing the housing component to be processed. The side plate is fixedly mounted with a pressure plate positioning component and a quick clamp positioning component for limiting and pressing the housing component to be processed. The side plate is vertically mounted on the base plate.

[0005] Preferably, the base plate is set parallel to the ground, and the angle between the side plate and the base plate is 90°.

[0006] Preferably, the pressure plate positioning component includes a number of heavy-duty pressure plate assemblies, which are symmetrically arranged at the upper and lower edges of the side plate. The quick-clamp positioning component includes a number of quick-clamp pressure plate assemblies, which are symmetrically arranged at the left, right, and upper edges of the side plate along the circumferential direction.

[0007] Preferably, the heavy-duty pressure plate assembly includes a pressure plate positioning block and a heavy-duty pressure plate. The heavy-duty pressure plate assembly is fixedly mounted on the side plate via the pressure plate positioning block. The body of the heavy-duty pressure plate has an adjustment waist-shaped hole. A bolt passes through the adjustment waist-shaped hole and engages with the pressure plate positioning block via a threaded connection. The heavy-duty pressure plate is detachably fixedly mounted on the front end of the pressure plate positioning block. The lower end of the body of the heavy-duty pressure plate has a pressure head. The rear end of the pressure plate positioning block has a limiting protrusion located on the side plate.

[0008] Preferably, the quick-clamp pressure plate assembly includes a quick-clamp pressure block and a quick-clamp support plate. The quick-clamp pressure block is fixedly mounted on the side plate by the quick-clamp support plate, and an extension pressure plate is fixedly mounted on the front end of the quick-clamp pressure block at the side plate.

[0009] Preferably, a main operating through hole is opened at the center of the side plate, and secondary operating through holes are opened at the four edges of the side plate. Upper and lower positioning pin holes are symmetrically opened at the secondary operating through holes at the upper and lower ends of the side plate, and left and right positioning pin holes are symmetrically opened at the secondary operating through holes at the left and right ends of the side plate.

[0010] Preferably, the side plate is fixedly mounted on the base plate by a rectangular square tube fixing frame, and there are reinforcing ribs between the side plate and the base plate.

[0011] By means of the above solution, this utility model has at least the following advantages:

[0012] The technical solution of this application can directly clamp and fix the housing parts that need to be welded by positioning fixtures. At the same time, since the side plates are set vertically, the housing parts can be positioned and also stand upright by using the side plates. This makes it easy for the robot to weld them directly, ensuring the dimensional accuracy of the parts clamping, while also ensuring the welding quality of the robot, improving production efficiency and reducing the manufacturing cost of enterprises.
