Description

Technical Field

[0001] This utility model relates to the field of aircraft parts processing technology, specifically to an aircraft parts processing positioning device. Background Technology

[0002] Aircraft parts machining positioning devices are specialized equipment used in the aerospace manufacturing field, primarily for precise positioning of aircraft parts during machining. Through a scientifically designed structure, these devices can stably fix aircraft parts in the required machining position, ensuring that the parts maintain their precise position during subsequent cutting, grinding, drilling, and other machining operations. This effectively improves machining accuracy and quality, providing a reliable guarantee for the precision production of aerospace manufacturing.

[0003] Traditional positioning equipment for aircraft parts machining has significant shortcomings. Most positioning devices have simple structures and single positioning methods, making it difficult to achieve precise fixation of parts. During machining, parts are prone to displacement or wobbling, resulting in large dimensional errors and low precision, seriously affecting the quality and performance of aircraft parts. Moreover, existing positioning devices lack flexible adjustment mechanisms, failing to adapt to different shapes and specifications of aircraft parts, resulting in poor versatility. Facing diverse part machining needs, frequent changes of tooling fixtures are required, which is not only cumbersome but also reduces production efficiency. Furthermore, some devices lack positioning stability, unable to withstand various external forces during machining, failing to provide a stable foundation for high-precision machining, and failing to meet the stringent requirements of high precision and high efficiency in the aerospace manufacturing field. Therefore, we propose an aircraft parts machining positioning device. Utility Model Content

[0004] One of the technical problems this application aims to solve is that existing aircraft part processing positioning devices have simple structures, single positioning methods, lack flexible adjustment mechanisms, and cannot be adapted to different shapes and specifications of aircraft parts, resulting in poor versatility.

[0005] To solve the above-mentioned technical problems, this application provides an aircraft parts processing positioning device, including a worktable. A groove is formed on the upper outer wall of the worktable. A slider is slidably connected to one side of the inner wall of the groove. A connecting groove is formed on both outer walls of the slider. A toothed block is fixedly connected to the lower outer wall of the slider. A gear is movably connected to the lower end of the slider. A connecting member is movably connected to one outer wall of the gear. A connecting block is movably connected to the outer wall of the connecting member away from the gear. A second cylinder is connected to the lower end of the connecting block. A limit rod is movably connected to one side of the inner wall of the gear.

[0006] In some embodiments, a controller is fixedly connected to one outer wall of the upper end of the worktable, a side plate is fixedly connected to one outer wall of the upper end of the worktable, a motor is fixedly connected to one outer wall of the side plate, a threaded rod is connected to one side of the motor, a movable block is movably connected to one outer wall of the threaded rod, a first cylinder is fixedly connected to one upper outer wall of one side of the movable block, a movable plate is connected to the lower end of the first cylinder, and a processing device is fixedly connected to one side of the movable plate.

[0007] In some embodiments, four sliders are provided and arranged in a circular array on the worktable, and are connected to corresponding grooves opened on the worktable.

[0008] In some embodiments, a limiting rod provided on one side of the inner wall of the gear is fixedly connected to one side of the inner wall of the worktable.

[0009] In some embodiments, the toothed block on the lower outer wall of the slider meshes with the upper end of the gear.

[0010] In some embodiments, the connecting grooves on the outer walls of both sides of the slider are correspondingly connected to the sliding grooves on the worktable.

[0011] In some embodiments, the lower end of the processing device provided on one side of the movable plate is correspondingly connected to the outer wall of the upper end of the worktable.

[0012] In some embodiments, the second cylinder is located at the top center of the inner wall of the worktable.

[0013] This utility model has at least the following beneficial effects: In use, this invention features a device with four annularly arrayed grooves and corresponding sliders. The sliders are slidably connected to the inner walls of the grooves via connecting grooves and mesh with toothed blocks and gears. When the second cylinder is activated, the longitudinal movement of the connecting blocks causes the gears to deflect, thereby enabling the sliders to move laterally through the interaction between the gears and the sliders. Due to the four-point positioning design of the sliders, when the connecting blocks move longitudinally, the four sliders slide towards each other, ensuring precise positioning of the aircraft parts and providing a stable foundation for subsequent processing operations.

[0014] In use, the motor drives the threaded rod to rotate, causing the movable block to move laterally along the threaded rod. This, in turn, drives the movable plate to move longitudinally via the first cylinder, enabling the processing device to perform multi-dimensional movements. Through the coordinated action of the motor and the first cylinder, the processing device can perform precise longitudinal and lateral machining of parts, thereby improving the flexibility and versatility of the machining process. It is particularly suitable for machining aircraft parts with complex shapes and multiple angles.

[0015] In use, the gear connects to the limiting rod during its movement, and the limiting rod provides stable positioning, ensuring that the gear rotates around the limiting rod and drives the slider to move precisely. This design ensures that the lateral movement of the slider is not disturbed by external factors, achieving precise positioning and stable movement, and avoiding errors or inconsistencies caused by slider instability during processing.

[0016] In use, this invention features a controller on the worktable that precisely controls the movement paths of the motor, cylinder, and slider. The operator can easily adjust these controls as needed, further enhancing the system's automation and ease of operation. This integrated control system makes the entire processing more efficient and reliable, avoiding errors caused by human error. Attached Figure Description

[0019] 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.

[0020] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: a positioning device for machining aircraft parts, including a worktable 1. A groove 3 is formed on the upper outer wall of the worktable 1. A slider 11 is slidably connected to one side of the inner wall of the groove 3. Four sliders 11 are arranged in a circular array on the worktable 1 and are correspondingly connected to the groove 3 on the worktable 1. A connecting groove 12 is formed on both outer walls of the slider 11, and the connecting grooves 12 on both outer walls of the slider 11 are correspondingly connected to the grooves 3 on the worktable 1. A toothed block is fixedly connected to the lower outer wall of the slider 11. 13. A gear 14 is movably connected to the lower end of the slider 11. A toothed block 13 on the outer wall of the lower end of the slider 11 meshes with the upper end of the gear 14. A connector 15 is movably connected to one side of the outer wall of the gear 14. A connecting block 16 is movably connected to the outer wall of the connector 15 away from the gear 14. A second cylinder 17 is connected to the lower end of the connecting block 16. The second cylinder 17 is located at the top center of the inner wall of the worktable 1. A limit rod 18 is movably connected to one side of the inner wall of the gear 14. The limit rod 18 on one side of the inner wall of the gear 14 is fixedly connected to one side of the inner wall of the worktable 1.

[0021] In this embodiment, a workbench 1 is designed with four sliding grooves 3 arranged in a circular array on the upper outer wall of the workbench 1. A slider 11 is provided on one side of the inner wall of each of the four sliding grooves 3. A connecting groove 12 is provided on both sides of the outer wall of the slider 11. The slider 11 can slide and connect with the inner wall of the sliding groove 3 through the connecting groove 12. Multiple toothed blocks 13 are fixedly connected to the lower outer wall of the slider 11. A gear 14 meshes with the lower end of the toothed blocks 13. A connecting block 16 is movably connected to one side of the gear 14 through a connecting member 15. A second cylinder 17 is connected to the lower end of the connecting block 16. The lower end of the second cylinder 17 is located at the middle of the top of the inner wall of the workbench 1. Therefore, when the second cylinder 17 is activated, it will drive the connecting block 16 to move longitudinally. When the gear moves, it will drive the gear 14 connected to the other side to shift through the connector 15. The gear 14 is movably connected to the middle of the limit rod 18, which is fixedly connected to the inner wall of the worktable 1. Therefore, the gear 14 will be limited by the limit rod 18 and rotate around the limit rod 18. At this time, the gear 14 drives the slider 11 to slide laterally on one side of the inner wall of the slide groove 3 by meshing with the tooth block 13. There are four connectors 15 in a ring array on the connecting block 16, and the other side of each of the four connectors 15 is connected to the gear 14 and the slider 11 that meshes with the gear 14. Therefore, when the connecting block 16 moves longitudinally, the four sliders 11 can move towards each other, thereby positioning the aircraft parts through the four sliders 11, and thus performing subsequent processing operations.

[0022] Example 2: Please refer to Figure 1-2A controller 2 is fixedly connected to one outer wall of the upper end of the worktable 1. A side plate 4 is fixedly connected to one outer wall of the upper end of the worktable 1. A motor 5 is fixedly connected to one outer wall of the side plate 4. A threaded rod 6 is connected to one side of the motor 5. A movable block 7 is movably connected to one outer wall of the threaded rod 6. A first cylinder 8 is fixedly connected to the upper outer wall of one side of the movable block 7. A movable plate 9 is connected to the lower end of the first cylinder 8. A processing device 10 is fixedly connected to one side of the movable plate 9. The lower end of the processing device 10 on one side of the movable plate 9 is correspondingly connected to the upper outer wall of the worktable 1.

[0023] In this embodiment, a controller 2 is fixedly connected to the outer wall of one side of the upper end of the workbench 1. The controller 2 can control the device to operate. A side plate 4 is fixedly connected to the outer wall of the upper end of the workbench 1. A motor 5 is fixedly connected to the outer wall of one side of the side plate 4. A threaded rod 6 is connected to one side of the motor 5. A movable block 7 is movably connected to the outer wall of the threaded rod 6. Therefore, when the motor 5 is started, the motor 5 will drive the threaded rod 6 to rotate. At this time, the movable block 7 can be driven to move laterally outside the threaded rod 6. A first cylinder 8 is fixedly connected to the outer wall of the upper end of one side of the movable block 7. The lower end of the first cylinder 8 is connected to a movable plate 9, and a processing device 10 is fixedly connected to one side of the movable plate 9. Therefore, when the first cylinder 8 is started, the first cylinder 8 will drive the movable plate 9 to move longitudinally, thereby driving the processing device 10 to move longitudinally. The lower end of the processing device 10 can be connected to the upper outer wall of the worktable 1. Therefore, the lower end of the processing device 10 can perform processing operations on the aircraft parts placed on the worktable 1. Under the action of the motor 5 and the first cylinder 8, multi-directional processing operations can be performed, making the processing of aircraft parts more diverse.
