This type of structure mainly uses high-performance titanium alloy, which has the characteristics of high strength, strong designability, and corrosion resistance. This type of structure is generally "T" shaped and mostly has a curved shape, which is prone to deformation. In order to reduce the amount of deformation, the outer surface needs to be shot peened.

[0003] The current approach typically involves placing the upper edge strip of the tail fin docking rib on a tooling fixture and then hoisting it to a shot peening machine for shot peening. However, the upper edge strip of the tail fin docking rib is prone to deformation during the shot peening process, which seriously affects product quality and may even result in defective products.

[0004] Therefore, there is an urgent need for a clamping fixture to solve the above problems. Utility Model Content

[0045] like Figures 1 to 7 As shown, this embodiment discloses a clamping fixture, including a fixture body 1, a positioning component 2, and a fixing component 3. A boss 11 is provided on the fixture body 1, which supports a workpiece 8. The positioning component 2 and the fixing component 3 are both disposed on the fixture body 1. The positioning component 2 is configured such that the workpiece 8 can abut against the positioning component 2 along a first direction and a second direction to position the workpiece 8. The fixing component 3 can press the workpiece 8 tightly against the boss 11 along a third direction. The first direction and the second direction are located in the same plane and are both perpendicular to the third direction.

[0046] Specifically, in this embodiment, the workpiece 8 is a tail wing docking rib upper edge strip structure. The tooling body 1 is a rectangular plate. The positioning boss 11 includes a plurality of bosses 11 that conform to the outer surface of the workpiece 8. The first direction is the length direction of the tooling body 1, the second direction is the width direction of the tooling body 1, and the third direction is the thickness direction of the tooling body 1.

[0047] It is understood that the clamping fixture provided in this embodiment, by providing a boss 11 on the fixture body 1, allows the positioning component 2 to abut against the workpiece 8 along the first and second directions, and the fixing component 3 to press the workpiece 8 against the boss 11 along the third direction. After the workpiece 8 is placed on the boss 11, the positioning component 2 and the fixing component 3 cooperate to press the workpiece 8 against the boss 11. By restricting the workpiece 8 in the first, second, and third directions, the clamping and fixing of the workpiece 8 is achieved. The structure is simple and the fixing is reliable, which allows the workpiece 8 to always be against the boss 11 of the fixture body 1 during the processing, thus avoiding deformation of the workpiece 8.

[0048] Furthermore, the positioning component 2 includes a first positioning member 21 and a second positioning member 22. The first positioning member 21 is configured to abut against the workpiece 8 in a first direction. The second positioning member 22 is configured to abut against the workpiece 8 in a second direction.

[0049] For example, such as Figure 2 and Figure 7 As shown, in this embodiment, the first positioning member 21 is a strip-shaped block, disposed at one end of the fixture body 1 along its length direction (first direction), and capable of abutting the wide side of the workpiece 8. The second positioning member 22 is a columnar structure disposed on the fixture body 1 along its width direction (second direction), and capable of abutting the long side of the workpiece 8. It can be understood that when using the clamping fixture, the wide side of the workpiece 8 is first abutted against the first positioning member 21, and then, while maintaining the abutment between the workpiece 8 and the first positioning member 21, the workpiece 8 is moved along the extending direction of the first positioning member 21 until it abuts against the second positioning member 22, thus completing the positioning of the workpiece 8.

[0050] Furthermore, the fixing component 3 includes a clamping member 31 and a connecting member 32. The connecting member 32 is disposed on the tooling body 1, and the clamping member 31 is disposed on the connecting member 32. The clamping member 31 can clamp the workpiece 8 along a third direction and fit it against the boss 11.

[0051] For example, such as Figure 1 and Figure 7 As shown, in this embodiment, the tooling body 1 has a plurality of fixing components 3 on one side with a boss 11. Each fixing component 3 includes a clamping member 31 and a connecting member 32. It can be understood that by setting the fixing components 3, the clamping member 31 in the fixing components 3 presses the workpiece 8 along the third direction and fits it against the boss 11. The fixing components 3 can cooperate with the positioning components 2 to limit the workpiece 8 in three directions, firmly fix the workpiece 8 on the boss 11, and ensure that the workpiece 8 will not deform during the shot peening process.

[0052] Furthermore, in some embodiments, the clamping member 31 includes an adjusting part 311 and a clamping part 312. The first end of the clamping part 312 is vertically connected to the adjusting part 311, and the second end of the clamping part 312 is used to clamp the workpiece 8. The adjusting part 311 is provided with an adjusting hole 3111, and the connecting member 32 passes through the adjusting hole 3111 and is connected to the tooling body 1.

[0053] Specifically, in this embodiment, such as Figure 3 As shown, the first end of the clamping part 312 is vertically connected to one end of the adjusting part 311, making the clamping part 31 L-shaped. The adjusting hole 3111 is a strip-shaped hole, provided along the extending direction of the adjusting part 311. The connecting part 32 is an internal hexagon screw, which passes through the adjusting hole 3111 and is threaded onto the tooling body 1.

[0054] More specifically, the tooling body 1 is provided with a connecting fixing seat 33, and the connecting piece 32 is fixed to the tooling body 1 through the connecting fixing seat 33. For example, the connecting fixing seat 33 is a threaded bushing, and the internal hexagon screw passes through the adjustment hole 3111 and is threadedly connected to the threaded bushing on the tooling body 1.

[0055] It is understandable that by providing an adjustment hole 3111 on the adjustment part 311, the clamping member 31 can move and / or swing relative to the connecting member 32 through the adjustment hole 3111, thereby clamping parts of different shapes. This eliminates the need to manufacture multiple clamping fixtures to accommodate different sizes, greatly improving the versatility of the clamping fixtures.

[0056] Furthermore, in order to better handle workpieces 8 with different curvatures, in some embodiments, the second end of the clamping part 312 is set as a semi-circle. It can be understood that by setting the second end of the clamping part 312 as a semi-circle, the clamping part 312 can ensure that the workpiece 8 fits against the corresponding boss 11 when clamping workpieces 8 with different curvatures, thereby improving the versatility of the clamping fixture.

[0057] Furthermore, in some embodiments, the tooling body 1 is provided with a plurality of connection holes 4, which are spaced apart on the tooling body 1, and at least the fixing component 3 is fixed to the tooling body 1 through the connection holes 4.

[0058] It is understandable that by opening multiple connection holes 4 on the fixture body 1, the number and position of the fixing components 3 can be flexibly set according to the clamping requirements of the workpiece 8, which greatly improves the versatility of the clamping fixture. By changing the position of the fixing components 3, parts with similar shapes can be clamped.

[0059] For example, in this embodiment, the fixing assembly 3 is fixed on the tooling body 1 through the connecting holes 4. By installing the fixing assembly 3 on the tooling body 1 through selecting different connecting holes 4, the fixing assembly 3 can be installed around workpieces 8 with different dimensions, so that the pressing portion 312 in the fixing assembly 3 can press workpieces 8 with different dimensions.

[0060] Further, in some embodiments, the clamping tool further comprises a connecting frame 5, the connecting frame 5 is arranged on the tooling body 1, a plurality of connecting holes 4 are arranged on the connecting frame 5, and the connecting frame 5 is used for fixing the tooling body 1. It can be understood that after the workpiece 8 is fixed, the tooling body 1 needs to be moved to a shot peening station. In order to facilitate fixing the clamping tool on the shot peening station, by arranging the connecting frame 5, the tooling body 1 can be better fixed on the shot peening station through the connecting holes 4 on the connecting frame 5, so as to ensure the subsequent shot peening effect.

[0061] Specifically, as Figure 1 , Figure 5 and Figure 7 shown, in this embodiment, there are three connecting frames 5, and a plurality of connecting holes 4 are also arranged at both ends of each of the three connecting frames 5. The three connecting frames 5 are arranged below both ends of the tooling body 1 along the length direction of the workpiece 8, and after the connecting holes 4 at one end of the connecting frames 5 are aligned with the connecting holes 4 arranged on the tooling body 1, they are connected through connecting fixing members 7. The connecting fixing member 7 comprises a bolt 71 and a nut 72. In order to improve the connection stability, a washer 73 is also arranged on the bolt 71. Among the three connecting frames 5, one connecting tooling body 1 is arranged at the first end of the tooling body 1 in a "grid" shape, and two "square-frame-shaped" connecting frames 5 are arranged at the second end of the tooling body 1. The three connecting frames 5 fix the tooling body 1 to the shot peening station through the connecting holes 4 at the end away from the tooling body 1. With this arrangement, the connecting frame 5 is arranged below the tooling body, so that the workpiece 8 is lifted, which enables better shot peening. Moreover, openings are arranged on the connecting frame 5 to reduce the weight of the connecting frame 5, which facilitates connecting the connecting frame 5 to the tooling body 1, and also facilitates subsequently moving the whole of the connecting frame 5 and the tooling body 1 to the shot peening station.

[0062] In some embodiments, the connecting frame 5 may not be provided, and the tooling body 1 can be directly fixed on the shot peening station through the connecting holes 4 arranged at the edge.

[0063] Further, in order to facilitate moving the tooling body 1, in some embodiments, a hoisting assembly 6 is arranged on the tooling body 1, and the hoisting assembly 6 is configured to enable the tooling body 1 to be lifted.

[0064] For example, in this embodiment, as Figure 1 and Figure 7As shown, four lifting assemblies 6 are provided, located at the four corners of the tooling body 1. It can be understood that by providing lifting assemblies 6, it is convenient to move the tooling body 1 to or from the processing station, and it can ensure the stability of clamping and fixing the workpiece 8 during the movement of the tooling body 1, ensuring that the workpiece 8 will not tilt and thus prevent poor subsequent processing results, effectively guaranteeing production quality.

[0065] Specifically, such as Figure 4 As shown, in this embodiment, the lifting assembly 6 includes a lifting handle 61 and a lifting handle fixing member 62. The lifting handle fixing member 62 is disposed on the tooling body 1 and can fix the lifting handle 61. More specifically, the lifting handle 61 is a lifting eye bolt, and the lifting handle fixing member 62 is also a threaded bushing disposed in the connecting hole 4 of the tooling body 1. The lifting eye bolt and the threaded bushing are threadedly connected, making the installation of the lifting assembly 6 convenient and quick.

[0066] Understandably, the diameter of the connecting hole 4 can be set to various sizes according to usage requirements. By setting the connecting hole to different sizes, it is easier to distinguish between various connecting holes and facilitate installation.

[0067] Specifically, in this embodiment, the connecting holes are divided into a fixed connecting hole 41, a bracket fixing hole 42, and a lifting connecting hole 43. A threaded bushing is provided in the fixed connecting hole 41, which can be threadedly connected to the connector 32. The bracket fixing hole 42 is located on the circumferential edge of the tooling body 1, facilitating the connection of the tooling body 1 to the connecting frame 5 via the connecting fastener 7, or fixing the tooling body 1 to the shot peening station. The lifting connecting hole 43 is used to install the lifting handle fastener 62.

[0068] Furthermore, in some embodiments, the tooling body 1 is provided with weight-reducing holes 12. It is understood that by providing weight-reducing holes 12 on the tooling body 1, the weight of the tooling body 1 can be further reduced, making it easier to move the tooling body 1 to the processing station.

[0069] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
