Description

Technical Field

[0001] This utility model relates to the field of aircraft landing gear technology, specifically an adjustable clamping support device. Background Technology

[0002] Rocker arms, strut arms, and torsion arms are core components of the landing gear system in aircraft structures, each performing different functions and affecting aircraft safety. The landing gear is an accessory device located under the aircraft, supporting it and facilitating ground movement during takeoff, landing, and taxiing. The landing gear is the only component that supports the entire aircraft; it is an indispensable and crucial part. The rocker arm, a bushing or shoulder of the landing gear strut, connects the shock absorber strut and the torsion arm, enabling the landing gear to extend and retract. It controls the extension and retraction of the shock absorber strut through rotational motion, thus raising and lowering the landing gear. The strut arm is the supporting structure connecting the shock absorber strut and the torsion arm. Its main function is to transfer loads and maintain the overall stability of the landing gear. In multi-strut landing gear systems, the strut arm and shock absorber strut together form the load-bearing frame. The torsion arm is a key component connecting the landing gear and the fuselage, supporting the fuselage by transferring weight and torque.

[0003] Rocker arms, support arms, and torque arms used in landing gear are all irregularly shaped parts. Their structural characteristic is a connecting rod structure with through holes. For such irregularly shaped parts, machining centers typically require a significant amount of preparation time for positioning before machining. Different models require the fabrication of various positioning fixtures, increasing both machining costs and time, resulting in low machining efficiency. Therefore, it is essential to provide an easy-to-operate support device for different models of rocker arms, support arms, and torque arms to facilitate their fixation, improve machining efficiency, and meet the needs of batch production.

Example 1

[0026] like Figure 1 and Figure 2As shown, this embodiment provides an adjustable clamping support device, including a base 1, a base 2, a smooth guide rail 3, a stop screw 4, a locking screw 5, and a locking assembly 6. The base 1 and base 2 are made of metal and have the same cuboid structure. There are two smooth guide rails 3. Each of the base 1 and base 2 has two guide holes 7 corresponding to the smooth guide rails 3. The base 1 and base 2 are connected by the smooth guide rails 3 installed in the guide holes 7. The smooth guide rails 3 located in the guide holes 7 are fixedly connected to the corresponding base 1 and base 2 by the stop screw 4. The top surface of the base 1 and base 2 has locking holes 8 corresponding to the locking assembly 6. There are two locking assemblies 6. The two locking assemblies 6 are installed on the corresponding base 1 and base 2 by the locking holes 8, and the locking assemblies 6 located in the locking holes 8 are fixedly connected to the corresponding base 1 and base 2 by the locking screw 5.

[0027] Furthermore, using the adjustable clamping support device provided in this embodiment, the guide holes 7 respectively penetrate through the two sides of the corresponding base 1 and base 2, and the two guide holes 7 are symmetrically arranged near the end faces of the base 1 and base 2. Two screw mounting holes 9 corresponding to the stop screws 4 are respectively provided on the end faces of the base 1 and base 2. The screw mounting holes 9 communicate with the guide holes 7, and the stop screws 4 are connected to the smooth guide rails 3 located in the guide holes 7 through the screw mounting holes 9.

[0030] The adjustable clamping support device described in this utility model works as follows: The spindle 61 in the locking assembly 6 is fixed to the corresponding base 1 and base 2 by locking screws 5. The distance between base 1 and base 2 is adjusted according to the length of the irregular part 13 to be processed. At this time, the irregular part 13 to be processed can be fixed on the worktable of the machining center by base 1 and base 2. Then, the smooth guide rail 3 is fixed to base 1 and base 2 by the stop screw 4, and the irregular part 13 to be processed is fixed by the spindle 61. Then, the adjusting washer 62 can be used to adjust to a height that is convenient for processing. Finally, the supporting washer 63 and the connecting nut 64 are used to completely fix the irregular part 13 to be processed on the two bases, and the processing work can be carried out in the machining center.

[0031] The main advantages of using the support device described in this utility model are as follows:

[0034] In terms of application: the adjustable clamping support device is particularly suitable for CNC machining centers, which can meet the needs of batch processing and increase work efficiency.

[0035] Therefore, the support device described in this utility model has an adjustable structure formed by the smooth guide rail 3 between the base 1 and the base 2, which facilitates the adjustment of the distance between the base 1 and the base 2. The smooth guide rail 3 is fixed by the stop screw 4, which realizes the fixation of the base 1, the base 2 and the smooth guide rail 3, and facilitates the fixation of the irregular parts to be processed. At the same time, the mandrel 61 in the locking assembly 6 passes through the irregular parts to be processed and is fixed by the locking screw 5, which prevents the irregular parts to be processed from shaking during the processing stage and further enhances its stability.

[0036] In summary, the support device described in this utility model, through the cooperation of base 1, base 2, smooth guide rail 3, stop screw 4, locking screw 5, and locking assembly 6, facilitates the fixing of irregularly shaped parts with perforated connecting rods. This enables the machining of a series of perforated connecting rod shapes and cavities, ensuring machining quality while allowing for rapid clamping and precise positioning. This reduces labor intensity, lowers costs, and improves work efficiency. Its overall structure is simple, rationally designed, convenient to operate and use, and suitable for widespread application.
