Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, and in particular to a positioning device for machining the fuselage rod of a four-axis UAV. Background Technology

[0002] The quadcopter fuselage struts are a component of the quadcopter's fuselage frame. There are typically four struts that connect the center of the fuselage to the motor mounting positions at the four corners. During manufacturing, positioning devices are needed to secure the struts. One such positioning device is a flat-jaw plier, which has the following structure:

[0003] 1. Pliers body: As the main frame of the flat-jaw pliers, it provides the mounting base for components such as the fixed jaw block, movable jaw block, and adjusting screw;

[0004] 2. Fixed clamping block and movable clamping block: The movable clamping block can move along the clamping body guide rail by adjusting the drive of the screw, and cooperate with the fixed clamping block to clamp or loosen the machine body rod;

[0005] 3. Adjusting screw: By rotating the adjusting screw, the rotational motion is converted into the linear motion of the movable clamp, thereby controlling the clamping force on the machine body rod.

[0006] During the machining of the quadcopter fuselage rod of a drone, a large amount of chips, coolant and other impurities generated by the machine tool cutting can easily splash onto the surface of the adjusting screw. Impurities can penetrate the thread clearance of the screw and adhere to its surface, which will accelerate the wear of the screw, leading to the screw rotation jamming, or even causing the screw to seize up or break, thus shortening the service life of the adjusting screw. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a positioning device for machining the fuselage rod of a four-axis UAV. It solves the technical problem that during the machining process of the four-axis UAV fuselage rod, a large amount of chips, coolant, and other impurities generated by machine tool cutting can easily splash onto the surface of the adjusting screw. These impurities can penetrate the thread clearance of the screw and adhere to its surface, accelerating screw wear, leading to screw rotation jamming, or even screw seizure or breakage, thus shortening the service life of the adjusting screw.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A positioning device for machining the fuselage rod of a quadcopter drone includes a movable clamp block. An adjusting screw is rotatably connected to the outside of the movable clamp block. A protective cover is provided on the outside of the movable clamp block to shield the adjusting screw. Fixing mechanisms for mounting the protective cover are provided at both ends of the movable clamp block. Each fixing mechanism includes a slide groove, a fixing plate, a spring, and a fixing slot. The slide groove is located on the outside of the movable clamp block. The fixing plate is slidably connected to the inside of the slide groove. The spring is located on the outside of the fixing plate and is used to support the fixing plate. The fixing slot is located on the side of the protective cover near the fixing plate. The fixing plate is slidably connected to the inside of the fixing slot and is used to fix the protective cover.

[0010] Preferably, each movable clamp has a limiting groove on one side corresponding to each slide, and a limiting plate is slidably connected inside each limiting groove. The limiting plate is set outside the fixed plate and is used to limit the movement range of the fixed plate.

[0011] Preferably, each fixed plate has a slot on its upper surface, the end of the limiting plate is engaged in the slot, each limiting plate has a limiting spring on its exterior to restrict its movement, each limiting plate has a deformation groove on its exterior, one end of the limiting spring is fixedly connected in the deformation groove, and each limiting plate has a pull groove on its exterior to move the limiting plate. This is a disassembly and assembly structure for the limiting plate, which facilitates the disassembly of the limiting plate to remove the fixed plate and the spring.

[0012] Preferably, a limiting shaft is fixedly installed inside each groove, a spring is movably sleeved on the outside of the limiting shaft, a fixed plate is slidably connected to the outside of the limiting shaft, and a movable ring is fixedly connected to both ends of each spring, with the movable ring slidably connected to the outside of the limiting shaft.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When installing the protective cover, press the fixing plates at both ends of the movable clamp block to make them enter the slide groove, then push the protective cover to fit and push it. When the fixing groove aligns with the fixing plate, use the spring force to make the fixing plate enter the interior of the fixing groove, thus installing the protective cover. Disassembly is performed in reverse order, which facilitates the quick installation and removal of the protective cover by the staff. When it is necessary to repair the internal components of the protective cover, the protective cover can be quickly disassembled, improving the convenience of operation. At the same time, the protective cover can shield the adjusting screw, preventing chips and coolant generated during processing from contacting the adjusting screw, avoiding wear on the screw caused by impurities, reducing the probability of screw failure due to impurity intrusion, ensuring the service life of the adjusting screw, and thus ensuring the stability of the entire positioning device.

[0015] 2. The slot and the end of the limiting plate cooperate to provide a snap-fit ​​position for the limiting plate. The limiting spring restricts the movement of the limiting plate. When the limiting plate is in the normal position, the limiting spring provides resistance to prevent the limiting plate from moving accidentally, thus enhancing the stability of the limiting plate in restricting the fixed plate.

[0022] This application provides a positioning device for machining the fuselage rod of a four-axis UAV, which effectively solves the technical problem that during the machining process of the four-axis UAV fuselage rod, a large amount of chips, coolant and other impurities generated by machine tool cutting are easily splashed onto the surface of the adjusting screw. The impurities invade the thread clearance of the screw and adhere to its surface, which will accelerate the wear of the screw, leading to the screw rotation jamming, or even causing the screw to seize up or break, thus shortening the service life of the adjusting screw.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that during the machining of the quadcopter fuselage rod of a UAV, a large amount of chips, coolant, and other impurities generated by machine tool cutting are easily splashed onto the surface of the adjusting screw. These impurities penetrate the thread clearance of the screw and adhere to its surface, accelerating screw wear, leading to screw rotation jamming, or even screw seizure or breakage, thus shortening the service life of the adjusting screw. The overall approach is as follows:

[0025] To address the problems existing in the prior art, this utility model provides a positioning device for machining the fuselage rod of a four-axis UAV, including a movable clamp block 1. An adjusting screw 15 is rotatably connected to the outside of the movable clamp block 1. A protective cover 2 is provided on the outside of the movable clamp block 1 to cover the adjusting screw 15. Fixing mechanisms for installing the protective cover 2 are provided at both ends of the movable clamp block 1. Each fixing mechanism includes a sliding groove 3, a fixing plate 4, a spring 5, and a fixing slot 6. The sliding groove 3 is opened on the outside of the movable clamp block 1. The fixing plate 4 is slidably connected to the inside of the sliding groove 3. The spring 5 is located on the outside of the fixing plate 4 and is used to support the fixing plate 4. The spring 5 is located inside the sliding groove 3. The fixing slot 6 is opened on the side of the protective cover 2 near the fixing plate 4. The fixing plate 4 is slidably connected to the inside of the fixing slot 6 and is used to fix the protective cover 2.

[0026] Each movable clamp 1 has a limiting groove 7 on one side corresponding to each slide 3. The limiting groove 7 communicates with the interior of the slide 3. Each limiting groove 7 has a limiting plate 8 slidably connected inside. The limiting plate 8 is set outside the fixed plate 4 and is used to limit the movement range of the fixed plate 4.

[0027] Each fixed plate 4 has a slot 9 on its upper surface. The end of the limiting plate 8 is engaged in the slot 9. Each limiting plate 8 has a limiting spring 10 on its exterior to restrict the movement of the limiting plate 8. Each limiting plate 8 has a deformation groove 11 on its exterior. One end of the limiting spring 10 is fixedly connected to the interior of the deformation groove 11, and the other end extends outward.

[0028] Each limiting plate 8 has a groove 12 on its exterior for moving the limiting plate 8.

[0029] Each groove 3 has a fixed limiting shaft 13 installed inside, a spring 5 is movably sleeved on the outside of the limiting shaft 13, and a fixing plate 4 is slidably connected to the outside of the limiting shaft 13.

[0030] Each spring 5 has a movable ring 14 fixedly connected to both ends, and the movable ring 14 is slidably connected to the outside of the limiting shaft 13.

[0031] Protective cover 2: It shields the adjusting screw 15, preventing chips, coolant and other impurities generated during the processing from coming into contact with the adjusting screw 15, reducing wear on the screw and screw failure caused by impurities entering;

[0032] Fixing mechanism: The slide groove 3 provides sliding space for the fixing plate 4 and accommodates the spring 5. The fixing plate 4 cooperates with the fixing groove 6 to fix the protective cover 2. During the installation and removal of the protective cover 2, the fixing plate 4 changes the connection state with the protective cover 2 by sliding in the slide groove 3. The spring 5 provides elastic support force for the fixing plate 4. When installing the protective cover 2, the spring 5 pushes the fixing plate 4 into the fixing groove 6 to fix the protective cover 2.

[0033] Limiting groove 7 and limiting plate 8: Limiting groove 7 provides a sliding track for limiting plate 8, limiting the direction and range of movement of limiting plate 8. At the same time, it is connected to slide groove 3, so that limiting plate 8 can restrict fixed plate 4 and prevent fixed plate 4 from being disconnected from slide groove 3 under the action of spring 5, thereby losing the fixation of protective cover 2.

[0034] Slot 9 and limiting plate 8: Slot 9 and the end of limiting plate 8 cooperate to provide a snap-fit ​​position for limiting plate 8. Limiting spring 10 is used to restrict the movement of limiting plate 8. When limiting plate 8 is inside slot 9, limiting spring 10 provides resistance to prevent it from sliding accidentally. When it is necessary to move limiting plate 8, the resistance of limiting spring 10 can be overcome to operate, which enhances the stability of limiting plate 8 in restricting fixed plate 4.

[0035] Deformation groove 11: provides an installation position for the limiting spring 10 and gives the limiting spring 10 a certain deformation space, so that the limiting spring 10 can play the role of limiting the movement of the limiting plate 8;

[0036] Slot 12: Provides a point of force for the operator to easily insert tools such as screwdrivers to pull the limit plate 8, thereby releasing the connection between the limit plate 8 and the slot 9, improving the convenience of disassembly and maintenance;

[0037] Limiting shaft 13: provides guidance for spring 5, ensuring that spring 5 does not deviate during extension and retraction;

[0038] Moving ring 14: Enables spring 5 to slide smoothly on limit shaft 13, while preventing excessive friction or separation between spring 5 and limit shaft 13 during extension and retraction.

[0039] Working principle:

[0040] First, when the positioning device is installed on the processing equipment, press the fixing plates 4 at both ends of the movable clamp 1 to make the fixing plates 4 enter the interior of the slide groove 3. At this time, the spring 5 is compressed. Then, one end of the protective cover 2 is attached to the outside of the movable clamp 1, and the protective cover 2 is pushed so that the inner side of the protective cover 2 is attached to the outside of the fixing plate 4. At this time, the fixing plate 4 is blocked by the inner side of the protective cover 2 and cannot move. Then, release the pressure on the fixing plate 4, and then continue to push the protective cover 2 so that the protective cover 2 completely covers the fixing plate 4. When the fixing groove 6 moves to the fixing plate 4, the fixing plate 4 moves into the interior of the fixing groove 6 under the action of the spring 5 to fix the protective cover 2. At this time, the installation of the protective cover 2 is completed.

[0041] The second step involves pressing the fixing plate 4 to disconnect it from the fixing groove 6 after prolonged use, then pulling the protective cover 2 to remove it from the movable clamp block 1. Next, a tool is inserted into the pull groove 12 to pull the limiting plate 8, disconnecting it from the slot 9. This removes the restriction of the limiting plate 8 on the fixing plate 4, allowing it to be pulled out of the slide groove 3. Then, the spring 5 is pulled to disconnect it from the limiting shaft 13, allowing a new spring 5 to be installed. By providing multiple operable structural components, operators can easily replace key parts, thus ensuring the protective effect of the protective cover 2.

[0042] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
