[0020] The following will be combined with the accompanying 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.

[0021] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0022] Please see Figures 1 to 6 The utility model provides a rotating part welding positioning tool, including a support plate 01 and a support frame 02 arranged opposite to the lower end surface of the support plate 01; the lower end of the support frame 02 is adapted to fit with the outer wall of the welding body 08, and a limiting groove 03 for limiting the workpiece 07 to be welded is provided on the lower end surface of the support plate 01, and a connecting hole 04 passing through the limiting groove 03 is opened on the upper end surface of the support plate 01 to facilitate connecting the workpiece 07 to be welded 07 with the support plate 01; the connecting holes 04 are evenly distributed circumferentially with the center of the limiting groove 03 as the reference. During welding, according to the relative position relationship between the workpiece to be welded and the welding main body 08, select a support frame 02 of appropriate height, assemble the support frame 02 and the support plate 01 first, and then fix the workpiece to be welded in the corresponding limit slot 03; after the above installation is completed, assemble the entire tooling and the workpiece to be welded 07 as a whole to the welding main body 08 (rotating body part), and preferentially fix the workpiece to be welded 07 by spot welding at the weld position. After that, you can decide whether to continue using the tooling to complete subsequent welding work according to actual needs.

[0023] In one embodiment, a groove 05 for positioning the support frame 02 is provided on the lower end surface of the support plate 01. When the support frame 02 is assembled, the end of the support frame 02 can be embedded in the groove 05, and the groove 05 is used to limit the lateral displacement of the support frame 02.

[0024] Of course, to facilitate effective connection and fixation between support plate 01 and support frame 02, as well as facilitate disassembly, a fixing hole 06 is provided on the upper end surface of support plate 01, which passes through groove 05. By inserting bolts into fixing hole 06 and the bolt holes on the upper end of support frame 02, support plate 01 and support frame 02 can be assembled.

[0025] In one embodiment, the lower end of the support frame 02 has an arc-shaped structure. This arc-shaped structure allows the end of the support frame 02 to better fit the outer wall of the welding body 08, thereby ensuring the stability of the support frame 02. Of course, the shape of the end of the support frame 02 can be adjusted based on the position of the workpiece to be welded on the welding body 08. For example, the shape of the end of the support frame 02 can be flat, curved, or irregularly curved. For different weld types, the structure of the support frame 02 can be adjusted to suit the relative position and connection between the workpiece to be welded 07 and the welding body 08, such as flat weld, curved weld, or irregularly curved weld.

[0026] In one embodiment, the height of the support frame 02 can be adjusted according to the relative position relationship between the workpiece 07 to be welded and the welding body 08.

[0027] Please see Figure 7 In one option, the support frame 02 can adopt a split structure, each support frame 02 can be overlapped and assembled by pin connection. When in use, the appropriate support frame 02 can be selected according to the use requirements, and assembled into a height that meets the requirements through the fixing pin 09.

[0028] Please see Figure 8 In one option, the support frame 02 can be two slidingly assembled support frames 02, wherein the uppermost support frame 02 can be fixed to the support plate 01 by bolts, and the lower support frame 02 can be slidably arranged on the upper support frame 02, and the two support frames 02 can be positioned by fastening screws 10. For example, when the height needs to be adjusted, the lower support frame 02 can be slid along with the upper support frame 02, and then the two can be fixed by fastening screws 10. Of course, in addition to the methods listed in this patent, other limiting and fixing methods can also be used for connection and fixation according to actual conditions.

[0029] Secondly, according to the welding properties of different welding materials, the corresponding welding shrinkage of the workpiece 07 to be welded can be increased on the theoretical height of the support frame 02 to ensure the accuracy of the workpiece after welding.

[0030] The above disclosure is only a preferred embodiment of the present invention, and it is certainly not intended to limit the scope of the rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the present invention.
