Description

Technical Field

[0001] The utility model belongs to the technical field of positioning tooling and relates to a pre-embedded iron plate positioning tooling. Background Art

[0002] When manufacturing the shell of a wind turbine nacelle, it is necessary to embed an iron plate in advance to facilitate its installation. When manufacturing the traditional shell of a wind turbine nacelle, most of the iron plates are embedded in advance first, and then tapped to facilitate bolt connection with the frame. Due to the process update, the current process has been changed from embedding and forming first and then punching to tapping and then embedding. This improvement has made the positioning accuracy requirements for the embedded iron plate higher. Before the process improvement, the embedded iron plate was positioned by measuring and gluing, but this positioning method has the following disadvantages: 1. Positioning by measurement is greatly affected by factors such as the operator's environment, and the accuracy cannot be guaranteed to be consistent; 2. It is fixed with glue and is easily pulled out of position during vacuuming; 3. This method cannot position the embedded iron plate on the curved surface or inclined surface. Therefore, for the updated manufacturing process, its positioning accuracy cannot meet the requirements.

[0003] In order to solve the above problems, it is necessary to design a positioning tool that can provide accurate and effective positioning and can also be applied to curved surfaces or inclined surfaces. Utility Model Content

[0006] Furthermore, the fixing assembly includes a positioning base and a fastener, the positioning base is inserted in a set position, and the fastener fixes the positioning base.

[0007] Furthermore, the positioning base is provided with a mounting channel, and the positioning column is further provided with a mounting portion, and the positioning column is detachably mounted on the positioning base through the mounting portion.

[0008] Furthermore, the top peripheral edge of the positioning base extends outward and obliquely downward to form a limiting flange, and the limiting flange is a trumpet-shaped structure that is small at the top and large at the bottom.

[0009] Furthermore, the positioning column further includes a second limiting portion and a limiting column head, and the limiting column, the second limiting portion, the first limiting portion and the mounting portion are sequentially arranged from top to bottom to form the positioning column.

[0010] Furthermore, the diameters of the limiting column, the second limiting portion, the first limiting portion and the mounting portion decrease in sequence.

[0011] Furthermore, the positioning column is also provided with a guide inclined surface, and the first limiting portion and the mounting portion are connected via the guide inclined surface.
