Description
Technical Field
[0001] This utility model belongs to the field of fixing device technology, and in particular relates to a fixing device for landing gear processing. Background Technology
[0002] Landing gear is a critical load-bearing component that supports the weight of the aircraft, absorbs landing impact, and ensures stability during ground movement when the aircraft is parked, taxiing, taking off, and landing. It is typically composed of core parts such as the outer cylinder, torque arm, piston rod, and joints. Because landing gear must directly bear the huge impact loads and complex stresses during takeoff and landing, its structural precision, strength, and surface quality must strictly meet aviation safety standards. Therefore, it is necessary to process raw materials or blanks into precision parts that meet design dimensions and performance requirements through machining processes such as milling, boring, grinding, and drilling. If landing gear parts are not fixed during the machining process, they are prone to displacement or deformation due to cutting forces, vibrations, and other factors, resulting in dimensional deviations, excessive surface roughness, or even scrapping of parts, which cannot meet the high precision and high reliability requirements of aviation safety for landing gear. Therefore, it is necessary to use fixing devices to ensure that the parts remain stable and precisely aligned with the machining coordinate system during machining.
[0003] However, when the existing fixing device is used, it is difficult to keep the device locked after the angle of the object to be processed is adjusted. This causes the part to deviate in angle due to cutting force, vibration and other factors during processing, which destroys the original processing position and causes the processing size deviation, resulting in the scrapping of the part. Utility Model Content
[0004] The purpose of this utility model is to provide a fixing device for landing gear processing. By setting an adjustment part, it solves the problem that in the use of existing fixing devices, after the angle of the object to be processed is adjusted, the device is difficult to keep locked. This causes the part to deviate in angle due to cutting force, vibration and other factors during the processing, which destroys the original processing position and causes the processing size deviation, resulting in the scrapping of the part.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a fixing device for landing gear processing, comprising a worktable, and further comprising: an adjustment part mounted on the worktable; a fixing part mounted on the adjustment part; the adjustment part including a locking assembly mounted on the worktable; and a rotating assembly mounted on the locking assembly; the locking assembly including a rotating disk penetrating the worktable, the rotating disk being rotatably connected to the worktable, a U-shaped plate fixedly connected to the outer wall of the rotating disk, a guide rod fixedly connected to the top of the U-shaped plate, a moving block slidably connected to the outer wall of the guide rod, a plurality of locking slots being provided on the worktable, a locking rod penetrating the moving block, the locking rod being fixedly connected to the moving block, the bottom of the locking rod penetrating the U-shaped plate, the locking rod being slidably connected to the U-shaped plate, the bottom of the locking rod being adapted to the plurality of locking slots, and an elastic element being provided on the outer wall of the locking rod; the moving block being positioned above the rotating disk, and the plurality of locking slots being distributed in a circumferential array.
[0006] Furthermore, the fixing part includes a driving component mounted on the rotating disk; and a fixing component disposed above the rotating disk; the driving component is used to drive the fixing component to fix it.
[0007] Furthermore, the rotating assembly includes a rotating groove formed on the inner wall of the worktable, and a retaining ring is fixedly connected to the outer wall of the rotating disk; the outer wall of the retaining ring extends into the rotating groove, and the retaining ring is rotatably connected to the rotating groove.
[0008] Furthermore, the fixing part includes a driving assembly, which includes a motor fixedly connected to the bottom of the rotating disk. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. A disc is fixedly connected to the outer wall of the rotating shaft, and a sliding element is provided on the disc. The disc is located above the rotating disk.
[0009] Furthermore, the fixing component includes several T-shaped grooves formed on the top of the rotating disk, each of the T-shaped grooves having a movable rod slidably connected to its inner wall, and each of the movable rods having an L-shaped fixing plate fixedly connected to one side of each other; the L-shaped fixing plates are all positioned above the rotating disk.
[0010] Furthermore, the elastic element includes a spring sleeved on the outer wall of the locking rod; the top of the spring is fixedly connected to the moving block, and the bottom of the spring is fixedly connected to the U-shaped plate.
[0011] Furthermore, the sliding member includes a plurality of sliding grooves formed on the disc, and a sliding rod is fixedly inserted through the inner wall of each of the plurality of sliding grooves. The plurality of sliding rods are slidably connected to the plurality of sliding grooves respectively; the bottom of the plurality of sliding rods is fixedly connected to a plurality of moving rods respectively.
[0012] This utility model has the following beneficial effects: 1. By setting an adjustment part, the rotation adjustment and locking of the part can be easily realized by pulling, rotating and releasing the locking rod. This greatly simplifies the operation of adjusting the part angle and saves adjustment time. The spring force can drive the locking rod to automatically reset and insert into the locking groove, ensuring that the part can be quickly and stably locked after rotating to the target position, avoiding the part from shifting due to poor locking during processing. 2. By setting up a fixing part, the motor can drive the relevant components to move, allowing multiple L-shaped fixing plates to move closer to each other synchronously. This enables the landing gear parts to be quickly self-centered and clamped. Multiple L-shaped fixing plates clamp synchronously from different directions, which can make the parts more evenly stressed and avoid the parts shifting or deforming caused by clamping in one direction.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-5 As shown, this utility model is a fixing device for landing gear processing, including a worktable 111, and further including: an adjustment part 2, which is installed on the worktable 111; and a fixing part 3, which is installed on the adjustment part 2.
[0019] The adjustment unit 2 includes a locking assembly 21, which is mounted on the worktable 111; and a rotating assembly 22, which is mounted on the locking assembly 21. The locking assembly 21 includes a rotating disk 211 that passes through the worktable 111 and is rotatably connected to it. A U-shaped plate 212 is fixedly connected to the outer wall of the rotating disk 211. A guide rod 213 is fixedly connected to the top of the U-shaped plate 212. A moving block 214 is slidably connected to the outer wall of the guide rod 213. Several locking slots 215 are provided on the worktable 111. A locking rod 216 passes through the moving block 214 and is fixedly connected to it. The bottom of the locking rod 216 passes through the U-shaped plate 212 and is slidably connected to it. The bottom of the locking rod 216 is adapted to the several locking slots 215. An elastic element is provided on the outer wall of the locking rod 216. The moving block 214 is located on the rotating disk 211. Above 1, several locking slots 215 are arranged in a circular array. The rotating component 22 includes a rotating groove 221 opened on the inner wall of the worktable 111. A retaining ring 222 is fixedly connected to the outer wall of the rotating disk 211. The outer wall of the retaining ring 222 extends into the rotating groove 221. The retaining ring 222 is rotatably connected to the rotating groove 221. The elastic element includes a spring 217 sleeved on the outer wall of the locking rod 216. The top of the spring 217 is fixedly connected to the moving block 214, and the bottom of the spring 217 is fixedly connected to the U-shaped plate 212. By setting the locking part 2, the rotation adjustment and locking of the part can be conveniently realized by pulling, rotating and releasing the locking rod 216. This greatly simplifies the operation of adjusting the angle of the part and saves adjustment time. The elastic force of the spring 217 can drive the locking rod 216 to automatically reset and insert into the locking groove, ensuring that the part can be quickly and stably locked after rotating to the target position, avoiding the part from shifting due to insecure locking during processing.
[0020] The fixing part 3 includes a drive assembly 31, which is mounted on the rotating disk 211; and a fixing assembly 32, which is positioned above the rotating disk 211. The drive assembly 31 drives the fixing assembly 32 for fixing. The fixing part 3 includes the drive assembly 31, which includes a motor 311 fixedly connected to the bottom of the rotating disk 211. The output shaft of the motor 311 is fixedly connected to a rotating shaft 312 via a coupling. A disc 313 is fixedly connected to the outer wall of the rotating shaft 312, and a sliding element is provided on the disc 313. The disc 313 is located above the rotating disk 211. The fixing assembly 32 includes several T-shaped grooves 321 formed on the top of the rotating disk 211. Each of the T-shaped grooves 321 has a sliding rod 322 slidably connected to its inner wall. L-shaped fixing plates 323 are fixedly connected to each other on the side that is close to each other; several L-shaped fixing plates 323 are set above the rotating disk 211. The sliding component includes several sliding grooves 314 opened on the disk 313. Sliding rods 315 are fixedly passed through the inner wall of several sliding grooves 314. Several sliding rods 315 are slidably connected to several sliding grooves 314 respectively. The bottom of several sliding rods 315 is fixedly connected to several moving rods 322 respectively. By setting the fixing part 3, the motor 311 can drive the relevant components to move, so that multiple L-shaped fixing plates 323 move closer to each other synchronously. The landing gear parts can be quickly self-centered and clamped. Multiple L-shaped fixing plates 323 clamp synchronously from different directions, so that the parts are subjected to more uniform force and avoid the parts from shifting or deforming due to clamping in one direction.
[0021] It should be noted that the control of motor 311 in this application can be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.
[0022] One specific application of this embodiment is as follows: In use, the landing gear component to be fixed is first moved above the worktable 111, positioning it between several L-shaped fixing plates 323. Then, the motor 311 is started, causing it to drive the disc 313 to rotate via the rotating shaft 312. At this time, several moving rods 322, under the interaction of the sliding groove 314 and the sliding rod 315, are brought closer together by the restriction of the T-shaped sliding groove 321, thereby causing the several L-shaped fixing plates 323 to move closer together, clamping and fixing the landing gear component to be fixed. After fixing, the component can be processed. If it is necessary to rotate the part, the locking lever 216 can be pulled upward until the locking lever 216 is completely disengaged from the corresponding locking groove 215. During this process, the moving block 214 will also move upward, and the spring 217 will be stretched, undergoing elastic deformation and generating tension. Then, the rotating disk 211 is rotated, and the part rotates accordingly until the part rotates to the required position. Then, the locking lever 216 is released, the spring 217 releases its elastic force, and the moving block 214 pulls the locking lever 216 downward until the locking lever 216 is inserted into the corresponding locking groove 215, thus completing the locking of the rotating disk 211 and the part.
