At the same time, the stably fixed parts can achieve high-speed processing, reducing pauses and adjustments during processing, and further improving the overall processing efficiency.

[0026] The entire rotating fixed tooling has clear positioning and limit mechanisms, and is easy to integrate with automated processing equipment, such as CNC machine tools, robot arms, etc., providing a hardware foundation for unmanned and intelligent production. At the same time, since the parts are stably fixed, the vibration of the processing process will be reduced accordingly, reducing equipment wear, extending the service life of the processing equipment, and reducing maintenance costs.

[0038] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0039] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0040] Reference Figure 1 to Figure 7 , which is the first embodiment of the utility model, proposes a high-precision special-shaped part rotating fixing tool for fixing part 1, including: a workbench 2; a positioning block 3, which is arranged on the workbench 2, and is used to position part 1 from the bottom; a high-precision limiter 4, which is arranged on the workbench 2, and is used to abut and limit the side of part 1.

[0041] In this embodiment, Figure 1 , 2As shown, since the traditional rotary fixing tool only relies on the positioning block 3, only a certain degree of positioning accuracy is guaranteed. The positioning block 3 is usually fixed from the bottom of the part 1 to facilitate the workers to install the part 1 in the early stage, so there is still a problem of positioning accuracy, that is, during the rotation processing of high-precision special-shaped parts, the part 1 may be displaced, thereby affecting the quality of the final product, so a high-precision limiter 4 is added to abut and limit the side of the part 1. This two-way positioning and fixing method ensures the precise position of the part 1 during the processing, avoids the processing error caused by the movement of the part 1, and improves the processing accuracy.

[0042] The rotary fixing tool can make specific adjustments in the early stage by setting the customized positioning block 3 and the high-precision limiter 4 for the high-precision special-shaped part 1 to ensure that even the special-shaped part 1 can be firmly fixed, and is suitable for the processing of various complex parts 1.

[0043] The entire fixing process: first align the bottom of the high-precision special-shaped part 1 with the positioning block 3, and then use the high-precision limiter 4 to limit its side, which reduces the centering adjustment time of the part 1 before processing and improves the efficiency of processing preparation. At the same time, the stably fixed part 1 can achieve high-speed processing, reducing pauses and adjustments during processing, and further improving the overall processing efficiency.

[0044] The entire rotating fixed tooling has clear positioning and limit mechanisms, and is easy to integrate with automated processing equipment, such as CNC machine tools, robot arms, etc., providing a hardware foundation for realizing unmanned and intelligent production. At the same time, since part 1 is stably fixed, the vibration of the processing process will be reduced accordingly, reducing equipment wear, extending the service life of the processing equipment, and reducing maintenance costs.

[0045] Furthermore, the positioning block 3 has a stepped portion 301 , and the stepped portion 301 is used to abut against the bottom surface of the component 1 .

[0046] In this embodiment, Figure 2 As shown, if the high-precision special-shaped part 1 is installed on the workbench 2, its bottom surface is completely in contact with the surface of the workbench 2, which may easily lead to inconvenience in subsequent disassembly and assembly. In order to ensure the positioning accuracy while ensuring that the disassembly of the part 1 is more convenient and does not involve violent disassembly to damage the high-precision special-shaped part 1, a corresponding step portion 301 is provided on the positioning block 3 to ensure that after the high-precision special-shaped part 1 is stably installed, the step portion 301 contacts and supports part of the bottom surface of the part 1, so that there is a gap between it and the surface of the workbench 2, so that the positioning block 3 can be fully utilized. At the same time, the part 1 can be disassembled from the gap. As long as the top surface of the step portion 301 is lower than the top surface of the overall positioning block 3, the part above the step portion 301 can be fixed from the bottom of the part 1.

[0047] Furthermore, there are a plurality of positioning blocks 3 , which are arranged at intervals, and the high-precision limiting member 4 is located between two adjacent positioning blocks 3 .

[0048] In this embodiment, Figure 2 As shown, customized settings are performed for high-precision special-shaped parts 1 of different specifications, and positioning blocks 3 are correspondingly arranged at various positions on the bottom. Therefore, several positioning blocks 3 are welded on the workbench 2, and several positioning blocks 3 are arranged at intervals to fully cover the bottom surface of the part 1, thereby playing a role of stable support and high-precision positioning.

[0049] The high-precision limiting component 4 is located between two adjacent positioning blocks 3. While avoiding the position of the positioning block 3, it provides a side abutment limiting effect on the part 1 from the area between the two adjacent positioning blocks 3, making the positioning more comprehensive and further improving the positioning effect.

[0050] Furthermore, it also includes: an adjustment block 5 , which is fixedly arranged on the workbench 2 , and has a slide groove 501 , and a high-precision limiter 4 is slidably arranged on the workbench 2 and passes through the slide groove 501 .

[0051] In the embodiment, Figures 1 to 4 As shown, during the fixing process, after the part 1 is initially positioned by the positioning block 3, the position of the high-precision limiter 4 may not be appropriate and cannot abut against the side of the part 1, and interference may even occur. To avoid the above situation, the high-precision limiter 4 is slidably set on the workbench 2 through the slide groove 501 of the adjustment block 5. Specifically, the adjustment block 5 is welded on the workbench 2, and the length direction of the slide groove 501 thereof only needs to ensure that the high-precision limiter 4 sliding therein can cover the position of abutting against the side of the part 1 in many cases. When the position of the high-precision limiter 4 in the slide groove 501 is determined, that is, when it abuts against the side of the part 1, the position of the high-precision limiter 4 is fixed by nuts and washers to complete the entire fixing work.

[0052] Furthermore, the high-precision limiter 4 is cylindrical, and the length of the high-precision limiter 4 is arranged vertically, and further comprises: a pressing plate 6, which is slidably arranged on the high-precision limiter 4, and is used to abut against the top surface of the part 1 after sliding.

[0053] Furthermore, it also includes: a locking nut 7, which is threadedly connected to the high-precision limiter 4, and the locking nut 7 abuts against the top surface of the pressure plate 6.

[0054] In this embodiment, Figures 1 to 4As shown, a pressure plate 6 is further slidably arranged on the high-precision limiter 4 arranged vertically along the column. Specifically, after the fixing work is completed, the pressure plate 6 can be stably locked on the top surface of the part 1 by sliding the pressure plate 6 and locking the locking nut 7, so as to further improve the positioning effect. The vertical setting can quickly move the pressure plate 6 to a suitable position while adapting to the horizontal top surface of the part 1.

[0055] Furthermore, the part 1 has a plurality of cylindrical parts 101 and a plurality of connecting parts 102 . The bottom surface of the cylindrical part 101 has a positioning groove 103 . The connecting part 102 is located between two adjacent cylindrical parts 101 . The positioning block 3 is used to extend into the positioning groove 103 . The pressure plate 6 is used to abut against the top surface of the connecting part 102 .

[0056] In this embodiment, Figure 4 As shown, a high-precision special-shaped part 1 composed of several cylindrical parts 101 and connecting parts 102 is usually used. The connecting part 102 is located between two adjacent cylindrical parts 101. When using the above-mentioned special-shaped part 1, the positioning groove 103 on the bottom surface of the cylindrical part 101 is installed on the positioning block 3, and the pressure plate 6 is pressed on the top surface of the connecting part 102, so that the part 1 is fully fixed, which greatly improves the overall positioning accuracy and avoids loosening during the processing process.

[0057] Furthermore, there are several high-precision limit parts 4, which are arranged along the circumference of the part 1, and the pressure plate 6 is mounted on the high-precision limit parts 4, and also includes: a connecting part 8, the connecting part 8 is located between the several pressure plates 6, and the several pressure plates 6 are detachably connected to the connecting part 8.

[0058] Furthermore, the workbench 2 has a rotating shaft portion 201, an extension line of the rotating shaft portion 201 passes through the center position of the connecting member 8 and the center position of the part 1, the bottom surface of the end of the connecting member 8 has an open groove 801, one end of the pressure plate 6 is interference fit with the open groove 801, and the bottom surface of the connecting member 8 and the bottom surface of the pressure plate 6 are both used to abut the top surface of the part 1.

[0059] In this embodiment, Figures 5 to 7 As shown, a number of high-precision limit members 4 are evenly distributed and arranged in a circular pattern to adapt to the shapes of most parts 1, ensuring that a number of high-precision limit members 4 can abut and limit the sides of the parts 1 at different positions, and the pressure plate 6 is sleeved on the high-precision limit members 4 to ensure that the pressure plate 6 can not only slide but also rotate relative to it to abut against a more suitable position of the part 1.

[0060] The precise alignment of the rotating shaft portion 201 of the workbench 2 and the center position of the connecting member 8 ensures the center positioning of the part 1 during rotation. This design not only improves the balance during rotation and reduces vibration, but also ensures the accuracy of rotation processing and avoids processing errors caused by eccentric rotation. At the same time, during the processing, the interference fit between one end of the pressure plate 6 and the opening groove 801 of the connecting member 8 can achieve quick clamping on the one hand, and on the other hand, for the opening groove 801, the design of the bottom surface of the connecting member 8 and the bottom surface of the pressure plate 6 can be realized to abut the top surface of the part 1 together, ensuring that the top surface of the part 1 can be limited at the same time, and the connecting member 8 will not interfere with the pressure plate 6, thereby reducing local stress concentration, improving the durability of the tooling, and extending its service life.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
