Abstract
Description
Technical Field
[0001] This utility model relates to the field of fixture technology, and in particular to a fixture for the production of aircraft parts. Background Technology
[0002] In the manufacturing process of aircraft parts, fixtures are an indispensable device. In addition to fulfilling the basic clamping function, fixtures must also have convenient pick-and-place operation characteristics.
[0003] In the existing technology, various specialized equipment and matching fixtures have emerged for the production and processing of drone wings. For example, Chinese utility model patent CN219597084U discloses a spraying equipment for drone wing production. This equipment, through a specific fixture structure design, can realize the picking and placing of drone wings in a relatively wide space, which to some extent solves the problem of limited picking and placing space in traditional equipment and improves the convenience of operation.
[0004] However, the inventors discovered in actual production practice that the clamping structure of the aforementioned spraying equipment still has significant defects. Specifically, during the loading and unloading process, the support rod needs to extend horizontally out of the spraying chamber by a considerable distance. This extended support rod lacks effective protection or avoidance design, making it highly susceptible to contact between the operator's arm and the support rod during loading and unloading operations, or between the wing itself and the support rod during transport. This contact can not only disrupt the smoothness of the loading and unloading operation and increase operational difficulty, but may also cause damage to the wing surface or deformation of the support rod structure due to the collision, thereby affecting the part processing quality and the service life of the clamp.
[0005] Therefore, in order to address the problem that components used in the existing jigs for drone wing production are easily bumped during the pick-and-place process, there is an urgent need to develop a new type of jig for aircraft parts production to avoid interference during the pick-and-place process. Utility Model Content
[0006] The purpose of this invention is to provide a fixture for the production of aircraft parts, which aims to solve the problem that components protruding from the coating chamber during the loading and unloading process of existing fixtures for the production of UAV wings are easily bumped.
[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0008] This utility model discloses a fixture for manufacturing aircraft parts, including a slide rail, on which a slider is slidably connected. The slider is equipped with a push-pull mechanism and a clamping mechanism for holding the wings of a drone.

The support is fixedly connected to the slider, and a limit component is provided on the support. One end of the abutment component is movably connected to the limit component, and the abutment component can switch between a horizontal and a vertical state.
[0009] Optionally, the limiting component includes a first round rod and a second round rod, the central axes of the first round rod and the second round rod are located on the same horizontal plane, the first round rod and the second round rod are spaced apart, the first round rod and the second round rod are both mounted on the support, and the first round rod is located at the end of the support near the door; the abutting component is movably connected to the first round rod, and the abutting component is detachably snapped into the second round rod.
[0010] Optionally, the abutting component has a groove and a waist-shaped hole, the first round rod passes through the waist-shaped hole, and the groove is detachably engaged with the second round rod.
[0011] Optionally, a third round rod is also included, which is fixedly connected to the support. The third round rod is located below the first round rod and the second round rod. When the abutting component is in a horizontal state, the third round rod contacts the lower surface of the abutting component. When the abutting component is in a vertical state, the third round rod may or may not contact the lower surface.
[0012] Optionally, the abutting component is a rod-column structure or a plate structure.
[0013] Optionally, a groove is formed along the entire length of the slide rail, the groove penetrates the bottom surface of the slide rail, and the top of the slider slides in cooperation with the groove.

[0032] In one specific embodiment of this utility model, a slide rail 200 is included, a slider 300 is slidably connected on the slide rail 200, and a push-pull mechanism and a clamping mechanism for clamping the wings of a drone are installed on the slider 300.
[0033] The clamping mechanism is existing technology and will be briefly described here. For details, please refer to [reference needed]. Figure 2 As shown, it includes a cylinder 1100, a mounting frame 1000, a clamping rod 1300, a connecting rod 1400, a clamping plate 1500, and a connecting block 1600. The mounting frame 1000 is fixedly connected to the slider 300. The cylinder 1100 is fixedly connected to the mounting frame 1000. The telescopic end of the cylinder 1100 is fixedly connected to the connecting block 1600. There are two clamping rods 1300 symmetrically arranged. One end of the clamping rod 1300 is hinged to the mounting frame 1000, and the other end of the clamping rod 1300 is fixedly connected to the clamping plate 1500. The two ends of the connecting rod 1400 are respectively hinged to the connecting block 1600 and the clamping rod 1300.
[0034] Additionally, the mounting frame 1000 can be rotatably connected to the slider 300; for details, please refer to... Figure 7As shown, a connecting plate is fixed on one side of the mounting frame 1000, and a rotating shaft is fixed on one side of the connecting plate. A bearing 1200 is mounted on the rotating shaft through an elastic retaining ring. The bearing 1200 is installed in a bearing hole opened on the slider 300. A motor is mounted on the slider 300, and the output shaft of the motor is connected to the rotating shaft through a key. With the above settings, the clamping mechanism can be rotated, thereby driving the UAV wing to rotate during the spraying process.
[0035] The push-pull mechanism includes a support 400 and an abutting part 500 for abutting against the door 100 of the spraying chamber. The support 400 is welded or bolted to the slider 300. A limit component is provided on the support 400. One end of the abutting part 500 is movably connected to the limit component, and the abutting part 500 can switch between a horizontal state and a vertical state.
[0036] In a specific embodiment of this utility model, the limiting component includes a first round rod 600 and a second round rod 700. The central axes of the first round rod 600 and the second round rod 700 are located on the same horizontal plane. The first round rod 600 and the second round rod 700 are spaced apart. Both the first round rod 600 and the second round rod 700 are mounted on the support 400 through elastic retaining rings. The first round rod 600 is located at the end of the support 400 near the door 100. The abutting component 500 is movably connected to the first round rod 600 and is detachably snapped into the second round rod 700.
[0037] In a specific embodiment of this utility model, the abutting component 500 is provided with a groove 510 and a waist-shaped hole 520, the first round rod 600 passes through the waist-shaped hole 520, and the groove 510 and the second round rod 700 are detachably snapped together.
[0038] In one specific embodiment of this utility model, a third round rod 800 is further included. The third round rod 800 is fixedly connected to the support 400, such as by welding or bolting. The third round rod 800 is located below the first round rod 600 and the second round rod 700. When the abutting component 500 is in a horizontal state, the third round rod 800 is in contact with the lower surface 501 of the abutting component 500 (i.e., they are tangent). When the abutting component 500 is in a vertical state, the third round rod 800 may or may not be in contact with the lower surface 501 (i.e., they are tangent or not tangent). After the UAV wing is clamped, the abutting component 500 is manually rotated, and the abutting component 500 gradually changes from a vertical state to a horizontal state. When it is in a submerged state, it is tangent to the third round rod 800 (i.e., it is tangent). Figure 4(As shown in the diagram), prevent it from swinging further, so that the groove 510 and the second round rod 700 are aligned. Then push the abutment member 500 to make the groove 510 engage with the second round rod 700. Continue to push the abutment member 500 until the slider 300 abuts against the limiting plate 220 away from the door 100. Close the door 100 and start spraying. After spraying is completed, open the door 100 and pull the end of the abutment member 500 to separate the groove 510 from the second round rod 700 (in the state shown). Figure 4 (As shown in the figure) Gently support the end of the abutment component 500. The end of the abutment component 500 away from the support 400 swings downward under the action of gravity and eventually becomes vertical.
[0039] In a specific embodiment of this utility model, the abutting component 500 is a rod-column structure or a plate structure.
[0040] In a specific embodiment of this utility model, a groove is provided along the entire length of the slide rail 200. The cross-section of the groove is dovetail-shaped or T-shaped. The groove penetrates the bottom surface of the slide rail 200, and the top of the slider 300 slides in cooperation with the groove.
[0041] In one specific embodiment of this utility model, a baffle 210 is fixed to the side of the slide rail 200 away from the spray chamber sidewall 900 by screws, and the baffle 210 extends downward to the top of the clamping mechanism. The baffle 210 can block the paint during the spraying process, effectively preventing paint from falling at the mating point between the slider 300 and the slide groove. Therefore, it is not necessary to wrap them with plastic film; only the clamping mechanism needs to be wrapped, reducing the preliminary preparation work.
[0042] In one specific embodiment of this utility model, limiting plates 220 for limiting the slider 300 are fixed at both ends of the slide rail 200. During the spraying process, the abutting component 500 abuts against the door 100, and the slider 300 abuts against the limiting plate 220 away from the door 100. By setting the limiting plate 220 close to the door 100, the slider 300 can be prevented from falling off the slide rail 200.
[0043] When using the fixture for manufacturing aircraft parts according to this utility model: after clamping the UAV wing, manually rotate the abutment component 500. The abutment component 500 gradually changes from a vertical state to a horizontal state. When it is in a submerged state, it is tangent to the third round rod 800 (at a horizontal position). Figure 4 (As shown in the diagram), prevent it from swinging further, so that the groove 510 and the second round rod 700 are aligned. Then push the abutment member 500 to make the groove 510 engage with the second round rod 700. Continue to push the abutment member 500 until the slider 300 abuts against the limiting plate 220 away from the door 100. Close the door 100 and start spraying. After spraying is completed, open the door 100 and pull the end of the abutment member 500 to separate the groove 510 from the second round rod 700 (in the state shown). Figure 4(As shown in the figure) Gently support the end of the abutment component 500. The end of the abutment component 500 away from the support 400 swings downward under the action of gravity and eventually becomes vertical. Since the abutment component 500 is vertical at this time, the situation of horizontally protruding and being touched is avoided when picking up and putting down the drone wing.
[0044] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably, and the embodiments can be combined with each other. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to in the method section.
[0045] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
