[0001] This utility model is applicable to the field of aircraft manufacturing tooling, and provides a riveting tooling for aircraft guides. Background Technology

[0002] Aircraft steering systems are crucial control components, primarily used to guide the movement of aircraft control surfaces and stabilize flight attitude. Steering systems typically consist of multiple metal components and supporting structures, requiring high strength and precision. During manufacturing, the various components are usually securely joined together using riveting. Riveting provides a durable mechanical connection, ensuring the steering system does not loosen, detach, or fail during use; therefore, the quality of the riveting directly affects aircraft safety.

[0003] In the manufacturing process of aircraft guides, commonly used riveting equipment mainly includes manual riveting tools and hydraulic or pneumatic riveting equipment. Manual riveting tools are generally suitable for smaller-scale riveting operations, while hydraulic or pneumatic riveting equipment is used for larger-scale riveting tasks that require higher precision.

[0004] Currently, the riveting process for aircraft guides mainly relies on manual operation, with workers using hand tools. However, due to differences in the operating skills, experience, and strength of each worker, the riveting effect fluctuates significantly, even resulting in inconsistent riveting quality. The pressure applied, the arrangement of rivets, and the depth may vary between workers during the riveting process, thus affecting the overall quality of the guide. Therefore, there is an urgent need for a new riveting fixture to improve the consistency and stability of riveting quality, reduce human error, and ensure the riveting accuracy of each guide. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0018] See Figure 1 , 2 The purpose of this utility model is to provide a riveting fixture for aircraft guides, including a base 01 and a mounting base 1 that can be assembled. The base 01 has a pre-drilled hole through which the mounting base 1 can pass. Specifically, the base 01 is fixed, and the bottom of the mounting base 1 is equipped with a lifting device and a turntable device that can drive it to rise and fall. When the lifting device lifts the mounting base 1 to the top, the top surfaces of the base 01 and the mounting base 1 are flush, completing the assembly. The lifting device is a common device on the market that can drive the equipment to rise and fall via a hydraulic system, and the turntable device is a common device on the market that can drive the platform to rotate via a motor. Since the lifting device and the turntable device are existing technologies and are very common on the market, their principles will not be described in detail here.

[0019] An "L"-shaped bracket 3 is fixedly connected to the top of the base 01. A guide sleeve 4 is fixedly connected to the end of the bracket 3 away from the base 01. The guide sleeve 4 is vertically continuous and internally houses a push rod 52. The upper and lower ends of the push rod 52 are fixedly connected to a pressure seat 51 and a top head 53, respectively. A spring 6 is installed between the pressure seat 51 and the top of the guide sleeve 4. The spring 6 abuts against the pressure seat 51, which can drive the push rod 52 to rise. The spring 6 plays a buffering role in the transmission of force and also has an automatic reset function. The top head 53, as the main load-bearing component, is made of Cr12 material and has undergone heat treatment to increase its hardness to a certain level.

[0020] The mounting base 1 has a detachable riveting support 2 on its top. Specifically, the bottom of the riveting support 2 has several positioning holes 21, and the top of the mounting base 1 is fixedly connected with several positioning pins 11 that correspond one-to-one with the positioning holes 21. Thus, the riveting support 2 can be placed on the top of the mounting base 1, and due to the cooperation between the positioning holes 21 and the positioning pins 11, the riveting support 2 will not slide relative to the mounting base 1.

[0021] The top surface of the riveting support 2 has several rivet recesses 22; these rivet recesses 22, along with the pressure ring 03, act as a guide and play a crucial role in connecting the upper and lower parts. The pressure ring 03 is detachably connected to the riveting support 2, specifically via hexagon socket bolts 20. The parts to be riveted are installed between the pressure ring 03 and the riveting support 2; the pressure ring 03, fixed to the riveting support 2, can press the two workpieces to be riveted together.

[0022] This tooling is suitable for riveting aircraft guide components, as shown in the attached document. Figure 1 Appendix Figure 2 As shown, the component comprises two parts: an aircraft guide 02 and a guide riveting part 06. The aircraft guide 02 has a connecting workpiece 05. Both the connecting workpiece 05 and the guide riveting part 06 have pre-drilled riveting holes in previous processes. Before riveting, the operator must first install rivets on the riveting support 2, align the riveting holes on the guide riveting part 06 and the connecting workpiece 05, and place them on the riveting support 2. This process can be completed with the assistance of mechanical equipment. Subsequently, a pressure ring 03 is placed on top of the connecting workpiece 05, and the pressure ring 03 is fixed to the riveting support 2 using an internal hex bolt 20. During the tightening of the internal hex bolt 20, the pressure ring 03 continuously presses down, thus clamping the parts to be riveted.

[0023] The above steps complete the assembly and fitting of the workpiece to be riveted with the tooling. Then, the assembled workpiece and tooling are placed on the mounting base 1, which is lifted to the riveting position by a lifting device. At this point, the top head 53 is perpendicularly aligned with the top of one of the rivets. The pressure seat 51 of the tooling is pressed down by mechanical equipment, causing the top head 53 to deform and complete the riveting. Subsequently, the lifting device and turntable work together to align the top head 53 with the next rivet, and so on, to complete the riveting process.

[0024] In actual production and processing, the "assembly and fitting of the workpiece to be riveted with the tooling" and the "riveting process" are two separate processes. This means that both processes can be carried out simultaneously. Semi-finished products assembled during the "assembly and fitting of the workpiece to be riveted with the tooling" process can be temporarily stored, increasing production flexibility. On the other hand, the fitting design of this tooling achieves high-quality riveting results; the riveted parts have a consistent and aesthetically pleasing appearance, while also reducing labor costs.

[0025] Preferably, the base 01, bracket 3 and guide sleeve 4 are all made of stainless steel and welded separately to ensure structural strength. Each edge is chamfered for an aesthetically pleasing appearance.

[0026] Preferably, the base assembly is composed of guide sleeve 4, bracket 3, and base 01. The inner diameter of guide sleeve 4 is made to correspond with the positioning hole 21 on mounting base 01 after welding, which ensures the coaxiality requirement and can accurately correspond with each rivet, so that guide sleeve 4 plays a better guiding role and ensures the riveting shape.

[0027] Preferably, the push rod 52 is provided with a retaining ring 54 that abuts against the bottom of the guide sleeve 4. The retaining ring 54 can ensure that the push rod 52 moves to a specified height when the spring 6 drives it to reset, thus playing a limiting role.

[0028] In summary, in actual use, the pre-assembly station first assembles the aircraft guide 02, connecting workpiece 05, and guide riveting part 06 with the riveting support seat 02 and pressure ring 03 according to the aforementioned steps to complete the "assembly and fitting of the workpiece to be riveted with the tooling". Subsequently, the semi-finished product is hoisted to the top surface of the mounting seat 1, and clamping is completed in one go using the quick positioning of the positioning pin 11 and positioning hole 21. The lifting device is activated, and the mounting seat 1 drives the semi-finished product to the riveting position. At this time, the upper plane of the base 01 is flush with the upper plane of the mounting seat 1, forming a rigid support. The turntable device rotates the position of the first rivet to directly below the top head 53 according to the program. The external press presses down the pressure seat 51, the top rod 52 descends vertically along the guide sleeve 4, the top head 53 applies forming force to the rivet, and the spring 6 is compressed. After riveting is completed, the press retracts, the spring 6 returns to its original position, and the top rod 52 returns to its initial height under the limit of the retaining ring 54. The turntable device continues to index sequentially, completing the forming of all rivets point by point. Once all riveting is complete, the lifting device lowers the mounting base 1, detaching it from the base 01. The finished product is then lifted off along with the riveting support base 02, and the cycle begins.

[0029] Therefore, the device can achieve parallel pre-assembly and riveting operations through modular and split structural design, which greatly improves cycle efficiency; the multi-level precise cooperation between the positioning pin 11 and the positioning hole 21, and the guide sleeve 4 and the rivet socket 22 ensures the coaxiality and forming consistency of each riveting point, making the appearance beautiful and the dimensions stable after riveting; the reset mechanism composed of spring 6 and retaining ring 54 not only buffers the impact but also ensures the reliable return of the top rod 52, reducing equipment wear; the stainless steel welded base assembly has high strength and corrosion resistance, and the chamfering treatment improves operational safety; the overall tooling can quickly replace the riveting support seat 2 and the pressure ring 03, which is compatible with the riveting requirements of various specifications of aircraft guides 02, significantly reducing manual intervention, reducing production costs and improving product quality and production flexibility.

[0030] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
