[0002] Thin-walled parts are widely used in machining, but due to the structural characteristics of thin-walled parts, the machining process is easily affected by stress, resulting in deformation of the parts. Especially in the outer circle polishing finishing step, the local deformation of the thin-walled part often affects the final accuracy and uniformity of the product. At present, there is a lack of effective and convenient thin-walled part polishing processing frock in the machining process to reduce or prevent deformation of the thin-walled part during machining. Therefore, the present application provides a part polishing processing frock. SUMMARY
[0003] In order to overcome the problems in the background art, the utility model provides a part polishing processing frock, which is convenient to use and solves the problem of deformation of thin-walled parts during machining.
[0004] To achieve the above purpose, the utility model is realized by the following technical scheme:
[0005] A part polishing processing frock, comprising a base, a middle shaft rod, a support sleeve core and a positioning piece, the base bottom is provided with a connecting piece, the base top surface is uniformly provided with a radial limiting block, the middle shaft rod is installed at the center of the base, the support sleeve core is provided with several layers of support sleeve cores which are sequentially sleeved outside the middle shaft rod, the support sleeve core bottom is provided with a limiting groove matched with the limiting block, and the positioning piece is uniformly installed around the base.
[0006] Further, the positioning piece comprises a positioning screw rod and a fastening head, the positioning screw rod is threadedly installed around the base, and the fastening head made of rubber is installed at the inner end of the positioning screw rod.
[0007] Further, the middle shaft rod comprises a plurality of detachably installed movable rod bodies, and the movable rod bodies are threadedly connected.
[0008] Further, the support sleeve core top is provided with a connecting block matched with the limiting groove.
[0009] The utility model has the advantages of:
[0010] The present application can effectively reduce or prevent deformation of the thin-walled part during the outer circle polishing process by supporting the inner cavity of the thin-walled part through the support sleeve core structure, significantly improving the machining accuracy and surface uniformity of the thin-walled part. The support sleeve core is provided with multiple layers, and the support sleeve core can be lengthened and installed, which can be adjusted according to the different sizes of the thin-walled part, and has good applicability and flexibility.
