[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The purpose of the utility model is to provide a pin positioning tool for blade production, so as to solve the problems existing in the above-mentioned prior art and effectively improve the production efficiency and qualification rate of blades.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] Example 1

[0027] like Figure 1-Figure 2 As shown, this embodiment provides a pin positioning tool for blade production, including a main body 1, a rod body 2 and four nuts. The main body 1 is fixed to one end of the rod body 2. One end face of the main body 1 is a first end face. Four insertion holes 3 are provided on the first end face. Each insertion hole 3 can allow each pin to pass through. The inner wall of each insertion hole 3 fits with the outer wall of each pin. Each nut is threadedly connected to each pin, and each nut can fix each pin in each insertion hole 3.

[0028] The pin positioning tooling provided in this embodiment for blade production is used in conjunction with a molding mold. By opening a socket 3 corresponding to the pin on the main body 1 and strictly controlling the opening accuracy of the socket 3, the four pins of the blade are installed in the corresponding socket 3 in advance when the blade is molded, and the position of each pin is locked by each nut to prevent the pins from shaking and misaligning during the blade molding process. That is, it can ensure that the form and position tolerances of the four pins at the root disc of the molded blade meet the requirements, so that the form and position tolerances of the root disc of the molded blade are greatly improved, which can effectively improve the production efficiency and pass rate of the blade.

[0029] Furthermore, the end face of the main body 1 away from the first end face is the second end face, and four operating grooves 4 are provided on the second end face. The bottom surface of each operating groove 4 is connected to each socket 3, and each nut is placed in each operating groove 4. Each nut can be pressed on the bottom surface of each operating groove 4 to fix each pin in each socket 3, so that each pin is set in each socket 3 and the operating groove 4, so that the main body 1 can effectively protect each pin and prevent each pin from being damaged by collision.

[0030] Furthermore, the main body 1 is an integrated structure, and the manufacturing error of each socket 3 is easier to control, which can effectively improve the manufacturing accuracy of each socket 3 on the main body 1.

[0031] As a more preferred implementation of this embodiment, the main body 1 and the rod body 2 are welded, which can improve the stability of the connection and is easy to manufacture.

[0032] Example 2

[0033] like Figure 3-Figure 4 As shown, the pin positioning tool for blade production provided in this embodiment is different from the pin positioning tool for blade production provided in Example 1 in that one difference is the structural form of the main body 1 and the second difference is the connection method between the main body 1 and the rod body 2.

[0034] In this embodiment, the main body 1 includes a first split body and a second split body. The first split body has two jacks 3, and the second split body has two jacks 3. The first split body and the second split body can be assembled into the main body 1, which is convenient for flexible disassembly and assembly.

[0035] Furthermore, the main body 1 also includes connecting screws, which fixedly connect the first split body and the second split body to facilitate manufacturing and disassembly.

[0036] Furthermore, a positioning groove is provided on the first split body, and a positioning protrusion is provided on the second split body. The positioning protrusion can be embedded in the positioning groove when the first split body and the second split body are assembled, thereby improving the assembly efficiency of the first split body and the second split body.

[0037] In this embodiment, the main body 1 and the rod body 2 can be disassembled, which is convenient for flexible disassembly and assembly.

[0038] As a more preferred implementation of this embodiment, the main body 1 and the rod body 2 are snap-connected to facilitate assembly and disassembly.

[0039] As another preferred implementation of this embodiment, the main body 1 and the rod body 2 are connected by bolts, which can effectively improve the stability of the connection.

[0040] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
