[0019] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following is in combination with the drawings and embodiment, and the utility model is further detailed.The specific embodiment described here is only used to explain the utility model, and is not used to limit the utility model.
[0020] In order to solve the technical problem that the three workpieces are prone to errors in manual assembly, the utility model provides an arc welding mistake-proofing tool, which can make the three workpieces have only one assembly mode, avoid the assembly error, and improve the yield of the product.
[0021] Please refer to Figure 2 And Figure 3 , Figure 2 The utility model discloses a structure schematic diagram of arc welding mistake-proofing tool; Figure 3 The utility model discloses a structure schematic diagram of arc welding mistake-proofing tool.
[0022] The arc welding mistake-proofing tool includes a base 1, a first limiting block 2 and a second limiting block 3, the base 1 is used for bearing the first limiting block 2 and the second limiting block 3, and is fixedly connected with the first limiting block 2 and the second limiting block 3, and fixes the relative position relationship between the first limiting block 2 and the second limiting block 3.
[0023] The first limiting block 2 is fixed on the upper surface of the base 1 and includes a first limiting column 21 for limiting the position of the first workpiece 4. The first workpiece 4 is a cylindrical structure and can be sleeved on the first limiting column 21.
[0024] The second limit block 3 is fixed on the upper surface of the base 1 . The two second limit blocks 3 are respectively arranged on both sides of the first limit block 2 . The second limit block 3 has a placement groove 31 for placing the second workpiece 5 and the third workpiece 6 .
[0025] The first limiting block 2 , the second limiting block 3 and the base 1 are generally connected by welding.
[0026] In some embodiments, the base 1 is a rectangular parallelepiped with a length, width, and height of 200 mm x 100 mm x 20 mm, and is generally made of steel.
[0027] In some embodiments, the first limiting block 2 further includes a second limiting column 22, the lower end of which is fixedly connected to the base 1, and the upper end of which is fixedly connected to the lower end of the first limiting column 21. The connection is usually made by welding.
[0028] In some embodiments, the first limiting post 21 and the second limiting post 22 are coaxially arranged. The diameter of the second limiting post 22 is larger than that of the first limiting post 21, thereby forming a circular stepped cylindrical structure. The first limiting post 21 is inserted into the corresponding small hole of the first workpiece 4, and the second limiting post 22 is used to control the height of the first workpiece 4 after being placed on the first limiting block 2. In this embodiment, the diameter of the first limiting post 21 is 22 mm.
[0029] In some embodiments, the two second limiting blocks 3 are symmetrically arranged with respect to the first limiting block 2 .
[0030] In this embodiment, the two placement grooves 31 are located on the same plane, and the plane where the two placement grooves 31 are located is eccentrically arranged with respect to the first limiting column 21. The second workpiece 5 and the third workpiece 6 can only be assembled in the placement groove 31 from one side, thereby achieving a unique assembly method.
[0031] In this embodiment, the width of the placement groove 31 is equal to the thickness of the second workpiece 5 and the third workpiece 6, so that the second workpiece 5 and the third workpiece can be just placed in the placement groove 31 and avoid shaking during welding.
[0032] In this embodiment, the bottom of the placement groove 31 is flush with the upper surface of the second limiting column 22, so that after assembly, the relative positions of the second workpiece 5, the third workpiece 6 and the first workpiece 4 along the axial direction meet the requirements.
[0033] In some embodiments, the second stopper 3 is formed with a positioning hole 32 that communicates with the placement slot 31. The positioning hole 32 is arranged parallel to the upper surface of the base 1. The arc welding error-proofing fixture also includes a pin that plugs into the positioning hole 32. After the first, second, and third workpieces are assembled on the fixture, the pin is inserted into the positioning hole 32 to fix the relative positions of the first, second, and third workpieces, preventing them from shifting during welding.
[0034] In this embodiment, one of the second limiting blocks 3 forms a circular positioning hole, and the other second limiting block 3 forms an elliptical positioning hole, thereby further enhancing the uniqueness of the workpiece assembly method.
[0035] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
