For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0038] The following shortcomings exist in existing coating methods for small UAV landing gear: (1) existing coating devices are complex in structure and inconvenient to use; (2) current coating devices cannot achieve uniform coating of the landing gear surface from all directions. This application provides a landing gear surface coating device, which is described below in conjunction with... Figures 1-4 The landing gear surface coating device is described in detail.
[0039] The landing gear surface coating device includes a support base 1, a drive unit 2, a transmission component 3, a clamping mechanism 4, and a first gear component 6. (Refer to...) Figure 1 As shown, the drive device 2 is located at the bottom of the support base 1, and the transmission component is located at the top of the support base 1. The drive end of the drive device 2 is connected to the transmission component 3. In actual use, when the drive device 2 is started, it can drive the transmission component 3 to rotate. (Referring to...) Figure 1 As shown, the first gear component 6 is fixed to the support base. (Referring to...) Figure 3 and with Figure 3 Taking the angle shown in the figure as an example, the clamping mechanism 4 includes a mounting base 41, a first clamping gripper 42, a second clamping gripper 43, a drive screw 44, and a second gear 5. The first clamping gripper 42 and the second clamping gripper 43 are spaced apart at the bottom of the mounting base 41, and the first clamping gripper 42 is slidably connected to the bottom of the mounting base 41, while the second clamping gripper 43 is slidably fixedly connected to the mounting base. Here, the drive screw 44 passes through the first clamping gripper 42 and connects to the second clamping gripper 43 via a threaded connection (the drive screw 44 is threaded to the first clamping gripper 42). The drive screw and the second clamping gripper 43 are connected via a bearing (the drive screw 44 has threads, and the end connected to the second clamping gripper 43 is a smooth end, also connected via a bearing). That is, when the drive screw 44 is rotated, because the drive screw and the second clamping gripper 43 are connected via a bearing, the second clamping gripper 43 remains fixed to the mounting base 41, while the first clamping gripper 42 moves along the axis of the drive screw 44, causing the first clamping gripper 42 to move closer to or further away from the second clamping gripper 43, thereby changing the dimensions of the mounting space enclosed between the first clamping gripper 42 and the second clamping gripper 43. Furthermore, this is still combined with… Figure 3 As shown, the second gear 5 is disposed on the circumferential side wall of the mounting base 41 and meshes with the first gear component 6; the mounting base 41 is rotatably connected to the transmission component 3.
[0040] The working process of the landing gear surface coating device provided in this application is as follows: First, the landing gear workpiece is placed in the installation space enclosed by the first clamping gripper 42 and the second clamping gripper 43. By rotating the drive screw 44, the first clamping gripper 42 can be driven to move towards the second clamping gripper 43, thereby clamping and fixing the landing gear workpiece in the installation space. Then, the drive device 2 drives the transmission component 3 to rotate. Since the transmission component 3 is rotatably connected to the mounting base 41, it will synchronously drive the second gear 5 to rotate around the central axis of the drive end of the drive device 2, that is, to achieve revolution. At the same time, since the first gear component 6 is fixed, and the second gear 5 meshes with the first gear component 6, the second gear 5 will be forced to rotate around its own central axis while revolving. That is, the workpiece can both rotate around the central axis of the drive end of the drive device 2 (revolution) and rotate around its own central axis.
[0041] As can be seen, the landing gear surface coating device provided in this application uses the clamping mechanism 4 to facilitate the clamping of the landing gear workpiece. The operation is simple and convenient, saving time and effort. Moreover, it can realize the landing gear workpiece's revolution while rotating itself, which can uniformly spray the coating agent onto the surface of the landing gear workpiece from all directions, reducing the existence of spraying dead corners and effectively improving the coating efficiency.
[0042] Of course, the landing gear surface coating device provided in this application is not only applicable to landing gear workpieces, but also to other workpieces, that is, to assist in coating other workpieces. It is simple and convenient to operate.
[0043] In one embodiment of this application, preferably, as shown below, Figure 1 and Figure 2 As shown, a second through hole is formed at the center of the second gear 5, and it is sleeved on the outside of the mounting base 41 through the second through hole.
[0044] In this embodiment, a second through hole is opened at the center of the second gear 5 to avoid interference, and to allow the teeth to be arranged around the outer periphery of the mounting base 41 so that the mounting base 41 coincides with the central axis of the second gear 5.
[0045] Furthermore, preferably, the mounting base 41 is a circular block, wherein its axis coincides with the central axis of the second gear 5.

Specifically, the first gear component 6 includes a fixed disk and a first gear. The fixed disk has a circular structure, the first gear extends along the edge of the fixed disk, and the first through hole is opened at the center of the fixed disk.
[0049] In one embodiment of this application, preferably, as shown below, Figure 1 and Figure 2 As shown, the first gear component 6 is disposed on the side of the second gear 5, and the two are at the same height, which facilitates the meshing of the two in the same horizontal plane.

Optionally, combined with Figure 3 As shown, both the slide groove and the slide rail 14 are T-shaped structures.

Of course, the structure of the first clamping gripper 42 and the second clamping gripper 43 is not limited to this and can be other structures, depending on actual needs.
