Description
Technical Field
[0001] The utility model relates to the technical field of mechanical processing, in particular to a thin-walled parts processing tool with multi-stage claw grooves. Background Art
[0002] In the fields of machining and precision parts manufacturing, especially for complex components such as engines within the machinery manufacturing industry, it is often necessary to machine thin-walled parts with special applications (such as sealing, guide grooves, and assembly) that have special groove structures, such as multi-stage claw grooves and dovetail grooves. These parts are typically made of difficult-to-cut materials such as stainless steel, titanium alloy, and high-temperature alloys, making machining extremely difficult. Traditional machining methods are inefficient and difficult to guarantee quality.
[0003] The complex structure of thin-walled parts with multi-stage claw grooves, including multiple levels of claw grooves, makes the clamping and machining of parts particularly difficult. Traditional machining methods often make it difficult to fully form the parts in a single pass, and it is difficult to ensure the dimensional accuracy of the special-shaped grooves and the required wall thickness of thin-walled parts. In addition, the thin-walled parts are prone to deformation during machining, further increasing the difficulty and uncertainty of processing.
[0004] To overcome these challenges, the industry has been exploring more efficient and stable machining solutions. However, existing machining tools and methods often cannot fully meet the machining requirements of multi-level claw groove thin-walled parts, resulting in low machining efficiency, unstable part quality, and even failure to meet design requirements.
[0005] Therefore, there is an urgent need for a new type of processing tool for multi-level claw groove thin-walled parts, which can solve the problems of clamping difficulties and processing deformation in traditional processing methods, improve processing efficiency and part quality, and meet the processing needs of the machinery manufacturing industry for such parts. Utility Model Content
[0006] In order to solve the above problems, the utility model provides a thin-walled parts processing tool with multi-level claw grooves. The thin-walled parts processing tool with multi-level claw grooves uses a designed non-standard special forming knife to process the corresponding claw grooves, which can ensure one-time processing and forming, without the need for tedious operations such as correction processing, and can be promoted and used in similar parts; the design of the T-shaped process base greatly reduces the difficulty of clamping parts, avoids the investment in complex tooling, and reduces the impact of clamping deformation of thin-walled parts. Compared with traditional processing, the processing efficiency is more than doubled, the quality is stable and reliable, and the cost is reduced.
[0007] The technical solution of the utility model is as follows:
[0008] A tool for processing thin-walled parts with multi-level claw grooves. The part body is provided with multi-level claw grooves from top to bottom and from outside to inside. The processing tool includes a turning blade, which is composed of a turning tool body and a tool head. The turning tool body is used to be fixedly connected to the turning tool rod of the lathe. The outer dimensions and angles of the tool head respectively match the dimensions and angles of the claw grooves of the part body to be processed.
[0009] The thickness of the cutter head is equal to the difference in the width of the claw groove.
[0010] The length of the cutter head is greater than the groove depth of the claw groove.
[0011] The rounded corners of the cutter head are consistent with the rounded corners of the claw groove bottom.
[0012] The tool for processing thin-walled parts with multi-stage claw grooves also includes a T-shaped process base, which is arranged at the bottom of the part body.
[0013] An incision is provided between the T-shaped process base and the part body. After the incision is removed, the T-shaped process base is separated from the part body.

[0020] The components represented by the reference numerals in the figure are:
[0021] The utility model comprises: 1. a part body, 1a. a claw groove, 2. a T-shaped process base, 3. a notch, 4. a turning blade, 4a. a turning tool body, 4b. a tool head. DETAILED DESCRIPTION
[0022] like Figure 1 and Figure 2 As shown, the tool for processing thin-walled parts with multi-stage claw grooves mainly includes a turning blade 4 and a T-shaped process base 2.
[0023] The turning insert 4 is composed of a turning insert body 4a and a insert head 4b.
[0024] The tool body 4a is designed with a standard mounting interface (which belongs to the existing technology and will not be described in detail in this article. Any mounting interface in the existing technology can be selected in implementation) for fixed connection with the tool rod of the lathe to ensure stability and precision during the turning process.
[0025] The outer dimensions and angle β of the tool head 4b are customized based on the specific dimensions and angle α of the claw groove 1a of the part body 1 to be machined. In this example, the thickness of the tool head 4b is precisely designed to equal the median width difference of the claw groove 1a to ensure that the machined groove width meets the design requirements.
[0026] The length of the tool head 4b is greater than the depth of the claw groove 1a to ensure that the claw groove structure can be completely turned out.
[0027] The rounded corners of the cutter head 4b are consistent with the rounded corners of the bottom of the claw groove 1a to ensure that the shape of the machined groove bottom meets the design requirements and avoids excessive burrs or machining allowances.
[0028] The T-shaped process base 2 is designed to solve the clamping difficulty of the part body 1 during the turning process.
[0029] The T-shaped structure facilitates connection with the lathe fixture, while providing sufficient support area to reduce the deformation of thin-walled parts during the clamping process.
[0030] A cutout 3 is provided between the T-shaped process base 2 and the part body 1. After feature processing is completed, the T-shaped process base 2 can be removed by a simple cutting process to separate the part from the base without the need for complicated subsequent processing.
[0031] The blank allowance of the part body 1 is set into a T-shaped process base 2 structure to ensure firm clamping and accurate positioning.
[0032] Install the part body 1 together with the T-shaped process base 2 on the fixture of the lathe and prepare for turning processing.
[0033] According to the number and depth of the claw grooves 1a of the component body 1, a layered and step-by-step turning processing scheme is adopted.
[0034] Turning is performed from top to bottom and from forward to reverse (i.e. following or catering to the groove angle) to reduce the deformation effect of turning force on the thin-walled structure of the part.
[0035] After each layer of claw groove turning is completed, necessary measurements and inspections are carried out to ensure that the processed size and shape meet the design requirements.
[0036] After all the claw grooves 1a are turned, a simple cutting process is performed to remove the cut 3 between the T-shaped process base 2 and the part body 1.
[0037] The separated part body 1 undergoes subsequent cleaning, inspection and quality assessment.
[0038] By employing the machining tools and turning method described in this specific embodiment, precise machining of thin-walled parts containing multi-stage claw grooves was successfully achieved. During machining, the custom-designed turning inserts and the layered, step-by-step turning method effectively reduced deformation of the thin-walled parts, ensuring accurate machining dimensions and shape. Furthermore, the T-shaped process base design significantly simplifies part clamping, improving machining efficiency and quality consistency. Compared to traditional machining methods, this embodiment significantly improves both machining efficiency and part quality.
