Description

Technical Field

[0001] The utility model relates to a generator processing device, in particular to a wind power stator bracket welding inspection tool. Background Art

[0002] The stator support of a wind turbine is one of the components of a wind turbine. The stator is the non-rotating part of the generator that houses the coils. The support ensures the stator remains stable during operation and holds it in place for the rotating rotor (the rotating part) to generate electricity.

[0003] The manufacturing process of the stator bracket requires welding, and in order to ensure the dimensional accuracy of the final product, welding inspection is required. The existing inspection method is to simply place the profiling template on the upper end of the stator bracket for direct inspection. The profiling template itself has poor fixation and is easily displaced during placement and subsequent testing. It cannot ensure that the position between the profiling template itself and the stator bracket is relatively fixed. Therefore, errors are very likely to occur during the inspection process, and experienced operators are required to perform reliable inspections. Accurate and effective deviation data cannot be provided quickly, and ultimately the overall shape contour of the stator bracket cannot be accurately inspected, resulting in machined dimensions exceeding tolerance or even scrapping, which will have a certain impact on production delivery time and cost control. Summary of the Invention

[0004] In order to solve the above technical problems, the purpose of the present utility model is to provide a wind turbine stator bracket welding inspection tool, including an inspection platform, on which a welding inspection tool component is detachably fixedly installed. The stator bracket to be inspected can be tested for dimensional accuracy through the welding inspection tool component. The welding inspection tool component includes two side plates and two platforms. The two side plates are relatively arranged at the left and right ends of the inspection platform, and the two platforms are relatively arranged at the front and rear ends of the inspection platform. The two side plates and the two platforms together constitute a detection area for placing the stator bracket to be inspected. A number of profiling templates are slidably arranged between the two platforms. The inspection platform is located in the inspection area and is also detachably fixedly installed with a number of positioning brackets and bracket adjustment components.

[0005] Preferably, the upper ends of the two platforms are fixedly mounted with a slide rail assembly, and the two ends of each profiling template are respectively fixedly mounted on the sliders of the slide rail assembly.

[0006] Preferably, the bracket adjustment component includes four jacks, which are respectively located at the four corners of the detection area, that is, adjacent to the ends of the side panels and the platform. The bracket adjustment component also includes four adjustment screws, which are respectively arranged in pairs at the two ends of the two corresponding platforms. Each adjustment screw is fixed on the platform through an adjustment plate, and the adjustment screw is threaded with the adjustment plate.

[0007] Preferably, there are two positioning brackets, and the two positioning brackets are respectively arranged at the corresponding side panels.

[0008] Preferably, both ends of each profiling template are provided with assembly grooves, the lower end of the assembly connecting block is fixedly mounted on the slider of the slide rail assembly, and the end of the profiling template is fixedly connected to the slider of the slide rail assembly through the threaded engagement of the fixing bolts with the assembly grooves and the assembly connecting block. Each profiling template is an arched structure, and a number of concave detection ports are evenly provided on the lower end edge of the profiling template.

[0009] Preferably, the profiled plate is an aluminum plate.

[0010] By means of the above solution, the present invention has at least the following advantages:

[0011] The technical solution of the present application can effectively control welding deformation by cooperating with the detection platform, welding inspection fixture components, profiling templates and bracket adjustment components to detect abnormal problem points in the welding blank through the inspection fixture, thereby ensuring the dimensional accuracy of the stator bracket after welding, and making the dimensions after machining meet the requirements of the drawings, so as to improve welding quality, reduce production costs and enable production to run in an orderly manner.

[0012] Specifically, the detection platform can realize the positioning and support of the stator bracket and the welding gauge component. The stator bracket itself can be fixed on the detection platform by the welding gauge component and remain motionless. The profiling template can slide regularly along the guide rail under the premise that the position of the stator bracket is fixed. In this way, the relative position between the profiling template and the stator bracket can be guaranteed to be fixed, and neither of them will have the problem of position movement, thereby ensuring the accuracy of precision detection.

In order to more clearly understand the technical means of the present invention and to implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings.
