[0019] As shown in the attached Figure 1 to the attached Figure 4 figures:

[0020] The missile shell welding tooling provided by the present utility model includes a front support block 1, a positioning support block 2, a shell model 3, a positioning operation block 4, an automatic lock 5, a position adjustment block 6, a quick clamp 7, a bolt fastener 8, a profiling press block 9, and a weldment 10. The front support block 1 and the positioning support block 2 are fixedly installed on the workbench through the bolt fastener 8. The shell model 3 is placed on the front support block 1 and the positioning support block 2. The positioning support block 2 is installed with the positioning operation block 4 through a hinge. Automatic locks 5 are fixedly installed on both the positioning operation block 4 and the positioning support block 2. The position adjustment block 6 is fixedly installed on the positioning operation block 4. The position adjustment block 6 is fixedly installed with the quick clamp 7 through the bolt fastener 8. The quick clamp 7 is fixedly connected with the two profiling press blocks 9 through the bolt fastener 8. The profiling press block 9 presses the weldment 10 on the shell model 3.

[0021] Embodiment 1:

[0022] Specifically, the front support block 1 and the positioning support block 2 are ingeniously designed to be arranged on one side of each other, forming a stable support structure. Both of these support blocks adopt a "concave" - shaped structure. This design not only increases the support area but also provides a recessed area that closely matches the shell model 3. These recessed areas ensure the stability and accuracy of the shell model 3 during the welding process, laying a solid foundation for the subsequent welding operation.

[0023] Specifically, a lock seat of the automatic lock 5 is fixedly installed on the positioning support block 2. The lock head of the automatic lock 5 is fixedly installed on the positioning operation block 4. After the positioning operation block 4 and the positioning support block 2 are accurately aligned, through the locking function of the automatic lock 5, the two can be tightly connected together, and the shell model 3 is firmly restricted therein. This design not only simplifies the fixing process but also significantly improves the reliability and accuracy of locking.

[0024] Specifically, two position adjustment blocks 6 are provided. These two position adjustment blocks 6 are respectively located on both sides of the welding fixture, and a quick clamp 7 is installed on each position adjustment block 6. With its efficient and convenient characteristics, the quick clamp 7 can quickly and firmly fix the welded part 10 on the shell model 3. In addition, by adjusting the position of the position adjustment block 6, the welder can flexibly adjust the specific position of the quick clamp 7 to meet different welding requirements.

[0025] Specifically, the quick clamp 7 is composed of components such as a clamp seat, a connecting rod, a handle, and a clamp arm. The clamp seat is firmly installed on the position adjustment block 6 through bolts, and the connecting rod is respectively rotatably connected to the clamp seat, the handle, and the clamp arm. This structural design enables the quick clamp 7 to easily achieve the opening and closing actions, facilitating the clamping and release of the welded part. At the same time, the clamp arm is also fixedly connected to the profiling pressing block 9 through a bolt fastener 8, and the design of the profiling pressing block 9 can better fit the shape of the welded part 10, improving the stability and accuracy of clamping.

[0026] Embodiment 2:

[0027] First, components such as the front support block 1, the positioning support block 2, and the shell model 3 are fixedly installed on the workbench according to the design requirements, and the fastening conditions of each component are checked. Align the positioning operation block 4 with the positioning support block 2, adjust the position of the front support block 1 according to the length of the shell model 3 to place the shell stably, and realize the tight connection between the two through the automatic lock 5. At this time, the shell model 3 is firmly restricted in the fixture, and the positioning is completed. According to the shape and size of the welded part 10, adjust the position of the position adjustment block 6 so that the quick clamp 7 can accurately correspond to the clamping position of the welded part 10. Operate the handle of the quick clamp 7 to open its jaws. Place the welded part 10 into the jaws, and operate the handle again so that the clamp arm presses the welded part 10 firmly on the shell model 3 through the profiling pressing block 9. After confirming that the welded part 10 has been accurately and firmly fixed, the welder can start the welding operation. During the welding process, the stability of the fixture and the fixity of the welded part need to be maintained to ensure the welding quality. After the welding is completed, inspect the welding quality. After confirming that there is no error, loosen the handle of the quick clamp 7 and remove the welded part 10. Finally, clean the fixture and the workbench to prepare for the next welding operation.

[0028] Any technical solution that uses the technical solution described in this utility model, or is designed by those skilled in the art inspired by the technical solution of this utility model and achieves the above technical effects, shall fall within the protection scope of this utility model.
