Description

Technical Field

[0001] This utility model relates to the field of composite material processing technology, and in particular to a composite material opening device with an auxiliary positioning structure. Background Technology

[0002] A drone is an aircraft that does not require a pilot to operate it directly from inside the cabin, but flies through remote control, autonomous programs, or preset routes. The composite material skin of a drone is a structural component covering the outer surface of the drone's body. Its main function is to maintain the drone's shape and give it good aerodynamic characteristics, thereby ensuring the drone's stability and efficiency during flight. During the assembly process of a drone, the composite material skin needs to be connected to other components. To achieve this connection, holes are usually made in the skin to install fasteners such as bolts and rivets.

[0003] In existing technologies, when drilling holes in composite material skins, after the operator determines the drilling position, it is difficult for the drilling head to be longitudinally aligned with the composite material at the determined drilling position. This can easily lead to skewed drilling, making it difficult to assemble the composite material. Furthermore, when the composite material needs to be drilled in rows at specified intervals, it is also difficult for the drilling head to accurately position the rows of holes. The drilling head or the position of the composite material needs to be manually moved, which can easily result in reduced drilling accuracy and mismatched drilling spacing. Utility Model Content

[0006] The auxiliary positioning component includes a first lead screw, which is fixedly connected to the output end of the first stepper motor, and a moving block is threaded onto the external part of the first lead screw.

[0007] As a further description of the above technical solution:

[0008] The movable block is slidably connected inside the transverse mounting frame. First pointing frames are fixedly connected to both sides of the movable block. A longitudinal mounting frame is fixedly connected to the upper surface of the movable block. Measuring rulers are fixedly connected to one side of the longitudinal mounting frame and both sides of the transverse mounting frame.

[0009] As a further description of the above technical solution:

[0011] As a further description of the above technical solution:

[0012] The longitudinal mounting bracket has a blocking block fixedly connected inside. A second stepper motor is fixedly mounted on the upper surface of the longitudinal mounting bracket. Gears are fixedly connected to the output end of the second stepper motor and one end of the second lead screw. The two gears are meshed together.

[0013] As a further description of the above technical solution:

[0016] The upper surface of the processing table is provided with a clamping assembly, which includes a slide rail. The slide rail is opened on the upper surface of the processing table. Two cylinders are fixedly installed on the upper surface of the processing table, and the output end of the cylinders is fixedly connected to a fixed shell.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model, through the setting of auxiliary positioning components, utilizes the measuring ruler and displacement sensor on the horizontal mounting frame to facilitate the measurement of the lateral movement distance of the first pointing frame, and the measuring ruler and displacement sensor on the vertical mounting frame to facilitate the measurement of the longitudinal movement distance of the second pointing frame. This facilitates the positioning of the lateral and longitudinal movement of the drill bit. Furthermore, under the action of the inclined laser emitter, the laser emitter emission point is aligned with the point where the drill bit falls vertically, thus facilitating the determination of the drilling position of the drill bit. The connecting frame slides outside the limiting rod, which facilitates the vertical guidance of the downward movement of the drill bit, helping to reduce the phenomenon of drill bit deviation and facilitating positioning assistance during drilling.

[0023] 2. This utility model, through the setting of the clamping component, uses the limiting frame to facilitate the limiting of both sides of the composite material to be drilled. When the limiting plate moves down, it is convenient to limit the upper part of the composite material according to the thickness of the composite material to be drilled, so that the left, right and upper and lower sides of the composite material are limited. The internal thread rod is wrapped around the outside of the stud, which helps to protect the stud and reduce the phenomenon of the stud getting stuck due to the contamination of drilling dust.

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.

[0033] As attached Figure 1-6 As shown, one embodiment of this utility model is provided: a composite material hole-opening device with an auxiliary positioning structure, including a processing table 1, a transverse mounting frame 2 fixedly connected to the upper surface of the processing table 1, a hydraulic cylinder 3 arranged above the processing table 1, a drive motor 4 fixedly connected to the output end of the hydraulic cylinder 3, a drill head 5 fixedly connected to the output end of the drive motor 4, a first stepper motor 6 fixedly installed on the inner wall of the transverse mounting frame 2, and an auxiliary positioning component arranged at the output end of the first stepper motor 6;

[0034] The auxiliary positioning component includes a first lead screw 7, which is fixedly connected to the output end of the first stepper motor 6. A moving block 8 is threadedly connected to the outside of the first lead screw 7, so that the first lead screw 7 drives the moving block 8 to move.

[0035] As attached Figure 3As shown, the movable block 8 is slidably connected inside the transverse mounting frame 2. First guide frames 9 are fixedly connected to both sides of the movable block 8, facilitating movement of the measuring scale 11 outside the transverse mounting frame 2 to observe the movement distance. A longitudinal mounting frame 10 is fixedly connected to the upper surface of the movable block 8. Measuring scales 11 are fixedly connected to one side of the longitudinal mounting frame 10 and both sides of the transverse mounting frame 2. A second lead screw 12 is rotatably connected inside the longitudinal mounting frame 10. A connecting block 13 is threaded onto the outside of the second lead screw 12, facilitating longitudinal movement of the connecting block 13 by the second lead screw 12. A hydraulic cylinder 3 is fixedly installed on the lower surface of the connecting block 13. A second guide frame 14 is fixedly connected to one side of the connecting block 13, allowing movement of the measuring scale 11 outside the longitudinal mounting frame 10 to observe the movement distance. For longitudinal movement, displacement sensors 15 are fixedly installed on one side of the longitudinal mounting frame 10 and one side of the connecting block 13 to monitor the movement distance. Based on the row drilling position requirements, the first stepper motor 6 and the second stepper motor 17 are controlled to start and stop. A blocking block 16 is fixedly connected inside the longitudinal mounting frame 10. The second stepper motor 17 is fixedly installed on the upper surface of the longitudinal mounting frame 10. Gears 18 are fixedly connected to the output end of the second stepper motor 17 and one end of the second lead screw 12. The two gears 18 are meshed. A fixing block 19 is fixedly connected to one side of the hydraulic cylinder 3. A laser emitter 20 is fixedly installed on the lower surface of the fixing block 19. It is installed at an angle to facilitate the alignment of the laser emitter 20 with the drilling end of the drill head 5, thereby facilitating the determination of the drilling position.

[0036] As attached Figure 1 As shown, a limiting rod 21 is fixedly connected to one side of the longitudinal mounting bracket 10, which guides the movement of the drive motor 4. A connecting frame 22 is slidably connected to the outside of the limiting rod 21. A connecting rod 23 is fixedly connected to the lower surface of the connecting frame 22. The connecting rod 23 is fixedly connected to one side of the drive motor 4. The connecting frame 22 facilitates the guidance and limitation of the drive motor 4 when it moves. A clamping assembly is provided on the upper surface of the processing table 1. The clamping assembly includes a slide rail 24, which is used to accommodate the stepper motor 27 and facilitate the sliding of the slider 30. The slide rail 24 is opened on the upper surface of the processing table 1. Two cylinders 25 are fixedly installed on the upper surface of the processing table 1.

[0037] As attached Figure 5 As shown, a fixed housing 26 is fixedly connected to the output end of the cylinder 25. A stepper motor 27 is fixedly installed on the lower surface of the fixed housing 26. A stud 28 is fixedly connected to the output end of the stepper motor 27. A limit frame 29 is fixedly connected to one side of the fixed housing 26 to limit the left and right sides of the composite material. A slider 30 is fixedly connected to the lower surface of the limit frame 29. Two sliders 30 are slidably connected inside the slide rail 24 to limit the movement of the limit frame 29. A limit block 31 is fixedly connected to one side of the limit frame 29 to limit the upper part of the limit plate 34.

[0038] As attached Figure 6 As shown, the external thread of the stud 28 is connected to the internal thread rod 32, and the internal thread groove is provided to match the thread of the stud 28. A connecting frame 33 is fixedly connected to one side of the internal thread rod 32, and a limiting plate 34 is fixedly connected to one end of the connecting frame 33 to limit the upper part of the composite material. The limiting plate 34 is slidably connected to the outside of the limiting frame 29.

[0039] Working principle: When in use, the composite material is placed on the processing table 1. Then, the controller drives the cylinders 25 on both sides to extend the output end of the cylinders 25, which indirectly drives the limiting frames 29 on both sides to move closer to each other, clamping the composite material on the left and right sides. Then, the stepper motor 27 is driven. The output end of the stepper motor 27 drives the stud 28 to rotate. The stud 28 drives the internal thread rod 32 to move down through the internal thread of the internal thread rod 32. The internal thread rod 32 drives the limiting plate 34 to slide down on the surface of the limiting frame 29 through the connecting frame 33, thereby clamping the upper and lower sides of the composite material, so that multiple sides of the composite material are fixed.

[0040] During drilling, based on the points marked by the operator, the first stepper motor 6 is started. The output of the first stepper motor 6 drives the first lead screw 7 to rotate. The first lead screw 7 drives the moving block 8 to slide inside the transverse mounting frame 2. When the moving block 8 drives the longitudinal mounting frame 10 to move, it simultaneously drives the first pointing frame 9 to move outside the measuring ruler 11 on the transverse mounting frame 2, thereby indirectly causing the transverse position of the drill head 5 to move. The transverse movement distance of the moving block 8 is measured by the displacement sensor 15 on the longitudinal mounting frame 10. The drilling position of the drill head 5 is then determined by the laser point of the inclined laser emitter 20. Then, the output of the second stepper motor 17 drives one of the gears 18 to rotate, which in turn drives the other gear 18 to rotate. The other gear 18 drives the second lead screw 12 to rotate, causing the second lead screw 12 to drive the connecting block 13 to slide inside the longitudinal mounting frame 10. This causes the second pointing frame 14 to move outside the measuring ruler 11 outside the longitudinal mounting frame 10. The longitudinal movement distance of the drill head 5 is measured by the displacement sensor 15 on the connecting block 13, thereby assisting in positioning.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
