Abstract
Description
Technical Field
[0001] The utility model mainly relates to the technical field of aerospace component production, and in particular to a tooling assembly for processing a thin-walled bushing. Background Art
[0002] Thin-walled bushings are a type of accessory commonly used outside of mechanical parts to achieve sealing, wear protection, etc. It is a thin-walled ring that acts as a liner. Thin-walled bushings are widely used, and are involved in the aerospace field.
[0003] Aerospace refers to the navigation activities of manned or unmanned aircraft or spacecraft in and outside the Earth's atmosphere, also known as space flight or cosmic navigation. During the production and manufacturing process, the inner hole surface of the thin-walled bushing used in aerospace usually needs to be processed. However, since the thin-walled bushing used in aerospace is a ring structure with a thin side wall, it is inconvenient to clamp and fix it. If the thin-walled bushing is directly clamped and fixed on the three-axis chuck, it will cause the thin-walled bushing to be squeezed and deformed, thereby affecting the final quality of the thin-walled bushing. Therefore, it is necessary to design a special processing tool for the clamp ring to solve the above problem.
[0004] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

[0027] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0028] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "provided with", "provided on" and the like 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 an indirect connection 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 the present invention can be understood according to specific circumstances. Example 1
[0029] See attached Figure 1-3 The present embodiment is a tooling assembly for processing thin-walled bushings, comprising a cylindrical fixing seat 1, a fixing shaft 14 is correspondingly provided in the middle of one side of the fixing seat 1, a placement groove 11 matching the size of the thin-walled bushing 4 is correspondingly provided in the middle of the other side of the fixing seat 1, and the fixing shaft 14 on the fixing seat 1 and the placement groove 11 are correspondingly located on the same axis. A plurality of ear grooves 12 are correspondingly provided around the notch of the placement groove 11, and the number, position and depth of the ear grooves 12 match the number, position and thickness of the ear plates 41 on the thin-walled bushing 4. A rotatable and tightly fixed rectangular pressing block 2 is correspondingly installed on one side of the ear groove 12 on the fixing seat 1, and the ear plate 41 of the thin-walled bushing 4 can be pressed and fixed by the rectangular pressing block 2, thereby realizing the pressing and fixing of the thin-walled bushing 4.
[0030] Specifically, a threaded hole 13 is correspondingly provided on one side of the ear groove 12 of the fixing seat 1, and a tightening screw 3 can be correspondingly installed in the threaded hole 13. A through hole 21 is correspondingly provided in the middle of the rectangular pressing block 2, and the tightening screw 3 passes through the through hole 21 on the rectangular pressing block 2 and then is screwed into the corresponding threaded hole 13. During installation, the position of the rectangular pressing block 2 is manually adjusted, and the screw 3 is tightened, so that the long side of the rectangular pressing block 2 can be correspondingly pressed on the ear plate 41 of the fixed thin-walled bushing 4. It is worth noting that when the rectangular pressing block 2 is rotated, the long side of the rectangular pressing block 2 cannot exceed the edge of the inner hole of the thin-walled bushing 4, so that the inner hole of the thin-walled bushing 4 can be processed smoothly. When the rectangular pressing block 2 is rotated to a certain angle, the rectangular pressing block 2 can completely avoid the top of the placement groove 11, so that the installation and replacement of the thin-walled bushing 4 can be smoothly carried out. The tightening screw 3 can be a butterfly screw, which is convenient for workers to operate. Example 2
[0031] See attached Figure 1-4, a tooling assembly for processing thin-walled bushings in this embodiment has the same general structure as that in embodiment 1, except that it also includes a plurality of annular fixing blocks 5 and a plurality of long rectangular pressing blocks (not shown in the figure). The outer wall diameter of the annular fixing block 5 is adapted to the diameter of the placement groove 11. An ear plate Ⅱ51 matching the number, position and thickness of the ear grooves 12 is provided around one side of the annular fixing block 5, and a placement groove Ⅱ52 is provided in the middle of one side of the annular fixing block 5 where the ear plate Ⅱ51 is provided, and the placement groove Ⅱ52 can also be provided through both sides. The size of the placement grooves Ⅱ52 on different annular fixing blocks 5 can match the size of thin-walled bushings 4 of different models. A plurality of ear grooves Ⅱ53 are provided around the notch of the placement groove Ⅱ52, and the number, position and depth of the ear grooves Ⅱ53 on different annular fixing blocks 5 can match the number, position and thickness of the ear plates 41 on thin-walled bushings 4 of different models. A through hole is also correspondingly provided in the middle of the long rectangular pressing block, and the tightening screw 3 can pass through the through hole on the long rectangular pressing block and then be screwed into the corresponding threaded hole 13. The number of the long rectangular pressing blocks matches the number of the annular fixing blocks 5; the length of the long rectangular pressing block matches the size of the thin-walled bushing 4 clamped and fixed in the annular fixing block 5, that is, the long side of the long rectangular pressing block can be pressed and fixed on the ear plate 41 of the thin-walled bushing 4, but cannot exceed the edge of the inner hole of the thin-walled bushing 4. Different annular fixing blocks 5 can be used in conjunction with long rectangular pressing blocks of different lengths, and different annular fixing blocks 5 and long rectangular pressing blocks can cooperate to press thin-walled bushings 4 of different sizes. It is worth noting that the position of the ear groove II 53 on the annular fixing block 5 corresponds to the position of the ear plate II 51, so that the long rectangular pressing block can be smoothly pressed on the ear plate 41 of the thin-walled bushing 4.
[0032] The annular fixing block 5 can be directly installed in the placement groove 11 of the fixing seat 1 and fixed by pressing with a long rectangular pressing block. For more convenient use, the annular fixing block 5 can also be installed in the placement groove 11 of the fixing seat 1 by magnetic attraction; that is, the annular fixing block 5 can be made of magnetic attraction material, the fixing seat 1 can be made of high carbon steel or iron metal that can be magnetically attracted, and the annular fixing block 5 can be installed in the placement groove 11 by magnetic attraction.
