Abstract
Description
Technical Field
[0001] The utility model relates to the field of numerical control machining, in particular to a numerical control turning tooling for bevel thin-walled parts. Background Technique
[0002] During the turning process, bevel thin-walled parts are indeed prone to deformation due to machining, which not only affects the shape and position tolerances of the parts, but also increases the number of rework times and costs.
[0003] In order to solve this problem and thus improve the machining efficiency and product quality. In the prior art, the deformation is often controlled by improving the machining process. For example, rough turning and finish turning are carried out in separate sequences, and the clamping force during finish turning is appropriately reduced to eliminate the deformation caused by excessive cutting force during rough turning. In addition, the machining sequence is reasonably arranged. For example, rough turning and finish turning of the inner hole are carried out first, and then the outer circle and bevel are machined to reduce the influence of the clamping force on the deformation of the workpiece. In the selection of cutting parameters, the deformation can also be reduced by optimizing the parameters. For example, by selecting a smaller depth of cut and a larger feed rate, and using a high cutting speed, the cutting force can be reduced, and the possibility of workpiece deformation can be lowered. At the same time, sufficient cutting fluid is poured, which can not only reduce the cutting temperature, reduce the thermal deformation of the workpiece, but also improve the stability of the cutting process.
[0004] However, from the perspective of cost control, although the above methods avoid the generation of deformation, the process time is greatly extended, increasing the time cost.
[0005] Therefore, if a tooling with a simple structure and easy assembly and disassembly can be adopted, and the tooling is used to assist clamping and machining, not only can manpower be saved, but also the production efficiency can be improved, the production cost can be reduced, the deformation problem of bevel thin-walled parts during the turning process can be effectively controlled, the product quality can be improved, and at the same time, the production cost and the rework rate can be reduced. Content of the Utility Model
[0006] To solve the problems existing in the prior art, the purpose of the utility model is to disclose a numerical control turning tooling for bevel thin-walled parts. By using the tooling to assist clamping and machining, not only can manpower be saved, but also the production efficiency can be improved, the production cost can be reduced, the deformation problem of bevel thin-walled parts during the turning process can be effectively controlled, the product quality can be improved, and at the same time, the production cost and the rework rate can be reduced.
[0007] To achieve the above effects, the present application discloses a numerical control turning processing tooling for an inclined thin-walled part. The inclined thin-walled part includes an annular main body. An inner inclined surface is provided at the inner edge of the annular main body, and an outer inclined surface is provided at the outer edge. The minimum thickness of the inner inclined surface and the outer inclined surface does not exceed 5 mm. Six groups of circular holes are arranged at equal intervals in a ring shape on the annular main body. The tooling includes a circular disk body. An inward circular sink is provided at the center of the circular disk body. Threaded holes corresponding one by one to the circular holes on the annular main body are provided in the circular sink, and bolts matching the threaded holes are also included.
[0008] Further, the bolt is an inner hexagon bolt.
[0009] Further, the diameter of the circular sink is not less than the diameter of the annular main body.
[0010] Further, the depth of the circular sink does not exceed 5 mm.

After using the tooling, the geometric tolerances of the products meet the technical requirements, improving the product test passing rate and reducing the part rework. Description of the Drawings
