[0002] With the rapid development of aerospace technology, various high-strength aluminum alloy thin-walled parts have been widely used. Thin-walled parts are prone to vibration and large processing deformation during processing, which makes the processing cost high and the cycle long. Practitioners have been seeking effective ways to solve such problems.

[0003] At present, when turning thin-walled parts, most of them use different fixtures designed according to the different sizes of the parts to fix them, and then use a single tool for turning.

[0004] In the current turning process, the material of the heat sink parts is aluminum alloy, and deformation is easy to occur during the processing with a single tool, which affects the precision. In addition, thin-walled parts of different sizes need to design different tooling fixtures, which is cumbersome and time-consuming. Therefore, there is an urgent need for a turning tool holder suitable for the processing of thin-walled heat sink parts to solve the above problems. Summary of the invention

[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model is described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary persons in the field without creative work are within the scope of protection of the utility model.

[0026] At present, when turning thin-walled parts, most of them are fixed by different jigs and fixtures designed according to the different sizes of the parts to be processed, and then a single tool is used for turning. In the current turning process, the material of the heat sink parts is aluminum alloy, and deformation is prone to occur during the processing with a single tool, which affects the precision. In addition, different jigs and fixtures need to be designed for thin-walled parts of different sizes, which is cumbersome and time-consuming. In view of the above technical problems, the utility model provides a turning tool holder suitable for the processing of thin-walled heat sink parts. When processing the thin-walled heat sink, the parts are processed on both sides at the same time, which can offset the mutual squeezing force and effectively reduce the deformation during the turning process of the thin-walled heat sink. The technical solution of the utility model is described in detail below with reference to specific examples.

[0027] Reference Figure 1 As shown, the utility model relates to a turning tool holder suitable for machining thin-walled heat sink parts, comprising a base 1 and a clamping portion 2, wherein the base 1 is fixedly mounted on a lathe.

[0028] Both sides of the clamping part 2 are provided with mounting grooves 3 for the turning tool to be inserted and installed. The clamping part 2 is threadedly connected with a clamping bolt 4. One end of the clamping bolt 4 is inserted into the mounting groove 3 to clamp the side of the turning tool. At the same time, the mounting groove 3 is provided with an open groove 31 for the turning end of the turning tool to extend out, and a closed groove bottom 32 is also provided, and the groove bottom 32 is facing away from the feeding direction of the turning tool.

[0029] For example, the turning tool holder can process both sides of the thin-walled heat sink simultaneously. When processing, two turning tools are used for end surface processing. The simultaneous processing of both sides can offset the force of mutual squeezing, and effectively reduce the deformation of the thin-walled heat sink during turning. In actual use, the turning tool in the installation groove 3 is installed and clamped by the clamping bolt 4. By loosening and tightening the clamping bolt 4, the turning tool can be installed and removed.

[0030] Specifically, in this embodiment, in order to improve the overall structural rigidity of the turning tool holder, the base 1 and the clamping portion 2 are integrally arranged.

[0031] In one embodiment, the overall structure of the installation slot 3 is further refined, and the side of the installation slot 3 is open.

[0032] It should be noted that the open arrangement can facilitate the user to clean the turning debris in the mounting groove 3. At the same time, the open arrangement can also facilitate the user to disassemble and assemble the turning tool and adjust the overall position of the turning tool.

[0033] In one embodiment, it is more preferred that, in order to further optimize the machining stability of the turning tool holder, the two mounting grooves 3 are arranged in a mirror image, thereby further improving the turning stability of the part.

[0034] In one embodiment, the clamping structure of the turning tool is further refined, wherein two clamping bolts 4 are correspondingly provided in the mounting groove 3, and the clamping bolts 4 are spaced apart along the length direction of the turning tool.

[0035] The original single clamping bolt 4 is specifically a point-type positioning clamping, and adding a clamping bolt 4 can change from point-type to line-type positioning clamping, which can enhance the clamping effect of the turning tool and improve the installation stability of the turning tool.

[0036] In this embodiment, it is more preferred that the clamping portion 2 is further threadedly connected with a positioning bolt 5 , and the positioning bolt 5 is located at the groove bottom 32 .

[0037] It should be noted that the setting of the positioning bolt 5 can adjust the protruding size of the turning tool. At the same time, during processing, the turning tool can also be force-positioned in the direction of turning feed, which also further improves the installation stability of the turning tool and facilitates the adjustment of the turning tool. Specifically, in this embodiment, the positioning bolt 5 and the two clamping bolts 4 are distributed on the same straight line.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
