Description

Technical Field

[0001] The utility model belongs to the technical field of wing processing, and in particular relates to a shell wing processing device. Background Art

[0002] The wing is generally located at the tail of the shell to maintain stability. It can also increase the heat dissipation area and play a guiding role in the flight of the shell. The traditional wing processing method requires the plate to be divided into pieces of bulk blanks. The processing requires five steps. The first step is milling thickness, the second step is milling shape and drilling, the fourth step is milling the positive windward surface, and the fifth step is milling the reverse windward surface. This processing process has many steps, long processing time and auxiliary time, and low production efficiency. At the same time, many steps will result in more clamping times and thus large cumulative errors, and the product qualification rate is not high. In addition, the blank materials need to be cut individually piece by piece, which results in serious material waste and a large workload. At the same time, the surface finish is prone to indentation during processing, and the surface quality is not high. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0022] like Figure 1 FIG. 1 is a structural diagram of a shell wing processing device provided by an embodiment of the utility model, wherein the processing device comprises:

[0023] A four-axis body 1, on which a fixing component is installed;

[0024] A tailstock 3, on which a live center 4 is mounted, and a workpiece 5 is mounted between the live center 4 and a fixed assembly;

[0025] The tool 6 cooperates with the workpiece 5 and is used for processing the workpiece 5 .

[0026] In one embodiment of the utility model, the artillery shell wing processing device is provided with a fixed component and a live center 4 to address the deficiencies in the prior art. Six blank profiles are selected as workpieces 5 according to the number of winglets. The workpieces 5 are positioned using the fixed component and the live center 4, and then processed in sequence using a tool 6. Only one process is required to complete all steps, and the production efficiency and product quality are doubled. One profile can process five winglets at a time. At the same time, the material area of ​​the profile used to process the winglets is the waste material that needs to be removed when processing a projectile tail, which can realize the transformation of waste materials into treasure and complete the processes of two products at the same time.

[0028] A center hole is formed at one end of the workpiece 5, and the center hole cooperates with the live center 4. The other end of the workpiece 5 is fixed by a self-centering three-jaw chuck 2.

[0029] The self-centering three-jaw chuck 2 is movably connected to the four-axis body 1, and the four-axis body 1 drives the self-centering three-jaw chuck 2 to rotate;

[0030] The live center 4 is movably connected to the tailstock 3, and the live center 4 has a telescopic amount.

[0031] The self-centering three-jaw chuck 2 is used as a fixed component, and a center hole is opened at one end of the workpiece 5. The self-centering three-jaw chuck 2 acts on the small outer circle of the workpiece 5. The end face of the workpiece 5 without the center hole is positioned on the end face of the chuck, and the live center 4 acts on the center hole of the workpiece 5. During processing, the four-axis body 1 can drive the workpiece 5 to rotate as needed, and the live center 4 can rotate with the workpiece 5, and has a certain amount of expansion and contraction, which can effectively prevent the workpiece 5 from vibrating during the processing process, and can also make the positioning of the workpiece 5 more accurate to prevent jumping.
