[0039] See also Figure 2 and Figure 3 The present invention provides a CNC machine tool 10 for processing transmission parts of unmanned aerial vehicles, which includes: a base 100, a protective cover 200, a cutting arm 300 and a stage 400.

[0040] See also Figure 2 and Figure 3The protective cover 200 is disposed on the base 100, and the base 100 is provided with an inclined portion 110 and a recovery box 120. The recovery box 120 is laid flat on the ground, and there is an angle between the inclined portion 110 and the ground. Preferably, the angle between the inclined portion 110 and the recovery box 120 is 45°.

[0041] See also Figure 3 and Figure 4 The cutting arm 300 is located on the inclined portion 110 , a feed slide 130 is provided on the inclined portion 110 , a loading platform 400 is provided on the feed slide 130 , and the feed slide 130 is used to drive the loading platform 400 to approach or move away from the cutting arm 300 .

[0042] See also Figure 5 The stage 400 includes a base plate 410, a bracket 420, a turntable 430, a flip motor 440 and a plurality of clamps 450. The base plate 410 is connected to the feed slide 130. The turntable 430 is rotatably disposed on the bracket 420. The flip motor 440 is used to drive the turntable 430 to be parallel to the inclined portion 110 or the horizontal ground.

[0043] A plurality of clamps 450 are slidably disposed on the turntable 430 , and the turntable 430 rotates to drive the clamps 450 to rotate. The transmission component 20 to be processed is clamped on the clamps 450 , and each clamp 450 can clamp one transmission component 20 .

[0044] The working principle of the CNC machine tool 10 for processing the transmission parts of the drone is as follows:

[0045] When finishing the transmission component 20, the stage 400 needs to be reset first. At this time, the feed slide 130 is started to move the stage 400 to the lower end of the inclined portion 110, and the turning motor 440 drives the turntable 430 to turn over, so that the end surface of the turntable 430 is parallel to the ground; wherein, due to the angle between the inclined portion 110 and the ground, the stage 400 will be close to the position where the worker stands when sliding down the inclined portion 110, so that the worker can clamp the transmission component 20 conveniently;

[0046] After the stage 400 is reset, the worker clamps the transmission components 20 to be processed on the fixtures 450 one by one. At this time, the fixtures 450 are arranged in a circular array with the turntable 430 as the center, and the preparation work is completed;

[0047] The machine tool is started, and the turning motor 440 drives the turntable 430 to turn, so that the end surface of the turntable 430 is parallel to the inclined portion 110, and then the feed slide 130 drives the stage 400 to rise along the inclined portion 110 until the turntable 430 moves to the position where the cutting arm 300 is located;

[0048] The cutting arm 300 mills one of the transmission components 20 on the rotating disk 430, and processes the center hole 21 and the top protrusion 23 on the transmission component 20; after the milling task is completed, the rotating disk 430 rotates, and moves the next transmission component 20 to be processed into the working area of ​​the cutting arm 300, so that each transmission component 20 is transferred one by one to the position where the cutting arm 300 is located for milling;

[0049] See also Figure 8 and Fig. 9 After completing the milling process, the cutting arm 300 changes the tool and switches the milling tool to a turning tool; at the same time, one of the fixtures 450 on the turntable 430 slides to the center position of the turntable 430, and the turntable 430 starts to rotate, driving the transmission component 20 on the fixture 450 to rotate, and the cutting arm 300 approaches the transmission component 20 to turn its outer wall; after completing the outer wall processing task of the transmission component 20, the turntable 430 pauses, the fixture 450 at the center position is reset, and the other fixture 450 slides to the center of the turntable 430, and the above steps are repeated to process the outer wall of each transmission component 20 one by one.

[0050] After finishing the finishing task, the stage 400 is reset again, and the worker takes away the finished transmission component 20.

[0051] It can be seen that the CNC processing machine 10 of the UAV transmission component can complete the milling and turning work on the transmission component 20, and multiple transmission components 20 can be clamped on the turntable 430 at the same time. Multiple transmission components can be processed at one time. The transmission component 20 does not need to be transferred to other machine tools during the processing, which can save half of the clamping time and save the time for dividing and transferring the transmission component 20. The finishing operation of all features of the transmission component 20 can be completed on a single machine tool without occupying the processing time of other equipment, which is conducive to the mass production of the transmission component 20.

[0052] Furthermore, the inclined portion 110 is inclined at the horizontal ground, and the end face of the turntable 430 is parallel to the inclined portion 110 during the milling and turning processes. At this time, the turntable 430 is inclined at the ground, and the cut edge materials slide down the inclined portion 110 under the action of gravity and fall into the recovery box 120; at the same time, the turntable 430 rotates during the finishing process, and the edge materials retained thereon can be thrown off, causing the edge materials to fall along the inclined portion 110, which can effectively reduce the probability of edge materials being retained on the machine tool, and there is no need to frequently clean the machine tool. When removing the edge materials, only high-pressure gas needs to be used to flush the surface of the stage 400, which can quickly remove the residual edge materials to keep the equipment clean, reduce the cleaning frequency, and help reduce the standby time of the machine tool during the cleaning process.

[0053] It should be noted that in the working principle of the above-mentioned CNC machine tool 10 for processing the transmission components of the drone, the transmission component 20 is milled and turned. During milling, the fixture 450 is distributed on the periphery of the turntable 430, and the cutting arm 300 moves the cutting transmission component 20; while in the turning process, the transmission component 20 needs to be moved to the center of the turntable 430, and the turntable 430 drives the transmission component 20 to rotate, so that the tool can trim its outer wall; the position of the fixture 450 changes during the switching process between milling and turning; it is necessary to configure a linear drive component on the turntable 430 to drive the fixture 450 to move, such as a cylinder, a linear motor, a slide, etc., and the operation of these drive components requires the connection of cables or hoses. However, during operation, the stage 400 needs to translate along the inclined portion 110, the flip motor 440 will drive the turntable 430 to flip, and the turntable 430 itself will also rotate. There are multiple clamps 450 on the turntable 430, and each clamp 450 needs to be configured with a separate linear drive component. When installing these drive components on the turntable 430, a large number of cables or hoses need to be connected. These cables or hoses are elastic themselves, and the resistance they generate will interfere with the movement of the turntable 430 and reduce the movement accuracy of the turntable 430. On the other hand, the turntable 430 has a wide range of activities, and involves translation, flipping and rotation. Due to its active characteristics, the wiring is difficult and the pressure of inspection and maintenance is high.

[0054] See also Figures 6 to 9 To solve the above problems, the turntable 430 includes a housing 431, a rotating motor 432, a follower plate 433, a loading shell 434 and a translation module.

[0055] The housing 431 is connected to the bracket 420 , the follower plate 433 is disposed at the center of the housing 431 , the carrier shell 434 covers the follower plate 433 , and the rotary motor 432 is used to drive the follower plate 433 to rotate.

[0056] See also Figure 6 and Figure 8 The translation module is located between the carrier shell 434 and the follower plate 433. The translation module includes a rotating shaft 510, a main gear 520, and a plurality of planetary gears 530 meshing with the main gear 520. The rotating shaft 510 is used to drive the main gear 520 to rotate, so that the plurality of planetary gears 530 rotate synchronously.

[0057] See also Figure 6 and Figure 7, a plurality of tracks 4341 are provided on the carrier shell 434, each track 4341 extends outward from the center of the carrier shell 434, a flange 451 matching the track 4341 is provided on the fixture 450, a connecting rod 540 is provided between the flange 451 and the planetary gear 530, the planetary gear 530 rotates to drive the fixture 450 to reciprocate along the track 4341; the plurality of planetary gears 530 rotate synchronously to drive the plurality of fixtures 450 to alternately move to the center position of the carrier shell 434. The carrier shell 434 is connected to the follower plate 433 by screws, and the rotating motor 432 can drive the follower plate 433 and the carrier shell 434 to rotate synchronously when it is started.

[0058] See also Figures 6 to 9 , the timing when the translation module drives the fixture 450 to move is:

[0059] 1. When the stage 400 is reset, each fixture 450 needs to be moved to a position away from the center of the turntable 430, such as Figure 5 As shown;

[0060] 2. When turning, each fixture 450 is moved alternately to the center position of the turntable 430, such as Figure 7 As shown;

[0061] Specifically, when the transmission component 20 is milled, the rotating shaft 510 drives the main gear 520 to rotate, thereby driving the clamps 450 to move along the track 4341. When all the clamps 450 leave the center of the carrier shell 434, the rotating shaft 510 stops rotating, and the rotating motor 432 is started, so that all the clamps 450 can "revolve" around the axis of the carrier shell 434, thereby transferring the transmission component 20 one by one to the working area of ​​the cutting arm 300 for milling operation.

[0062] After all the transmission components 20 are milled, the rotating shaft 510 starts to rotate, and drives the planetary gears 530 to rotate synchronously through the main gear 520. Since the planetary gears 530 and the fixture 450 are connected by the connecting rod 540, when the planetary gears 530 rotate, they will pull or push the fixture 450 through the connecting rod 540, so that the fixture 450 slides along the track 4341, and the fixture 450 is transferred to the center position of the carrier shell 434. In this way, when the rotating motor 432 is started, it can drive the fixture 450 to "rotate", and the turning tool approaches the fixture 450 to perform fine processing on the outer wall of the transmission component 20 thereon.

[0063] It should be emphasized that the clamp 450, the planetary gear 530 and the connecting rod 540 form a crank slider mechanism, and the rotational motion of the planetary gear 530 is converted into the reciprocating linear motion of the clamp 450, and the planetary gears 530 rotate synchronously. It is only necessary to stagger the fulcrum 11 on each planetary gear 530 that is connected to the connecting rod 540, so that each clamp 450 can alternately enter the center position of the carrier shell 434 without colliding.

[0064] The method of adjusting the planetary gear 530 is as follows:

[0065] See also Figure 8 and Fig. 9 , the number of fixtures 450 in the figure is 3. When adjusting the planetary gears 530, the main gear 520 is removed first, and at this time, each planetary gear 530 is in a free rotation state;

[0066] The pivot points 11 on all the planetary gears 530 are directed toward the center of the carrier shell 434, and one of the planetary gears 530 is rotated by 120°; then another planetary gear 530 is rotated by 240°. After the angle adjustment is completed, the main gear 520 is reinstalled to make each planetary gear 530 mesh with the main gear 520. Since the pivot points 11 on the three planetary gears 530 are staggered, the timing of the three fixtures 450 connected thereto entering the center position of the carrier shell 434 is also staggered. By controlling the rotation angle of the main gear 520, the fixture 450 at the corresponding position can be moved to the center position of the carrier shell 434 for turning operation. By analogy, if the number of fixtures 450 is 4, the angles that each planetary gear 530 needs to rotate are 0°, 90°, 180° and 270° respectively.

[0067] It should be emphasized that the power source for the translation of the multiple clamps 450 comes from the rotation of the rotating shaft 510. Only a single motor is needed to drive the multiple clamps 450 to slide, and the timing of entering the center position of the loading shell 434 for turning is staggered, which saves space and equipment manufacturing costs while greatly reducing the difficulty of wiring on the turntable 430. The turntable 430 is subject to little resistance when it moves. Only the cables of the motor need to be fixed, the number of cables is small, and the wiring difficulty is low. The cables are not easily pulled when the turntable 430 moves, and the probability of cable damage is small. It is also convenient to inspect and maintain the turntable 430 at a later time.

[0068] See also Figure 5 and Figure 6In one embodiment, the housing 431 is provided with two L-shaped support arms 4311, and the L-shaped support arms 4311 are rotatably connected to the bracket 420. The output end of the flip motor 440 is connected to one of the L-shaped support arms 4311. When the flip motor 440 is started, the housing 431 is driven to flip through the L-shaped support arms 4311, thereby making the turntable 430 parallel to the inclined portion 110 or the horizontal ground. Preferably, the base plate 410 is provided with an avoidance cavity 411 to provide the turntable 430 with a movable space to prevent the turntable 430 from colliding with surrounding components when flipping.

[0069] See also Figure 6 and Figure 7 In one embodiment, a profiling pin 452 is provided on the fixture 450. The profiling pin 452 fits the inner cavity of the transmission component 20 and is used to position the transmission component 20 to prevent the transmission component 20 from loosening during the cutting process.

[0070] In one embodiment, a roller (not shown) is disposed at the bottom of the recovery box 120 to facilitate the recovery box 120 to be pulled out from the base 100 to dump the waste generated during the cutting process.

[0071] See also Figure 3 and Figure 4 In one embodiment, the cutting arm 300 is provided with a horizontal slide 310, a longitudinal slide 320, an output shaft 330 and a tool 340. The horizontal slide 310 is used to drive the output shaft 330 to translate horizontally, and the longitudinal slide 320 is used to drive the tool 340 to approach or move away from the stage 400. Preferably, there are multiple tools 340, which can be switched to corresponding tools 340 according to processing requirements, such as switching to a milling tool when milling and switching to a turning tool when turning.

[0072] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
