Description

Technical Field

[0001] This utility model belongs to the field of automatic painting equipment, specifically relating to an automatic painting device for tilting rotor mirror blades. Background Technology

[0002] Tiltrotors are a new type of aircraft that integrates fixed-wing and helicopter functions. Their rotor blades are mirror images. Current blade painting generally uses a repetitive painting method for blades of the same type and direction. However, for tilt-rotor mirror images, the blades need to be repainted by changing the angle or spraying path. This method of painting lightweight tilt-rotor mirror images can easily lead to the following problems: When painting tilt-rotor mirror images, because the blades are in two completely different directions, if the spraying path is not changed, the paint surface will be incomplete, and there will be protruding areas on the left-hand rotor blades and concave curved surfaces on the right-hand rotor blades. If the fixed spraying arm stays in these areas for too long, paint will accumulate, ultimately resulting in uneven paint surfaces on the right-hand rotor blades and excessive paint dripping. Utility Model Content

[0003] This utility model proposes an automatic painting device for tilting rotor mirror blades, which can be installed on an automatic painting equipment to achieve the purpose of simultaneously painting left and right tilting rotor blades, breaking through the traditional single-blade painting and achieving efficient, stable and accurate painting effect.

[0004] This utility model discloses an automatic painting device for tilting rotor mirror blades. The device has a support base at the upper end of the base, and a synchronization mechanism in the support base. The synchronization mechanism controls the mirror-connected right and left painting arms. The base has a power unit and a transmission unit. The power generated by the power unit is transmitted to the synchronization mechanism through the transmission unit.

[0005] Advantageously, the synchronization mechanism has both translational and rotational degrees of freedom.

[0006] Advantageously, the synchronization mechanism includes a left synchronization mechanism connected to the left spray arm and a right synchronization mechanism connected to the right spray arm.

[0007] Advantageously, the left and right synchronization mechanisms are gear mechanisms that mesh with external gears.

[0008] Advantageously, the power unit is an electric motor.

[0009] Advantageously, the transmission device converts the torque output by the motor into the power of the synchronization mechanism.

[0010] Advantageously, the left spray arm has a left nozzle and the right spray arm has a right nozzle.

[0011] Beneficial effects:

[0012] 1. When the operator turns on the automatic spray painting equipment controller, two mirror blades can be sprayed simultaneously. While the left-hand blade is being sprayed according to the equipment trajectory, the right-hand blade is being automatically sprayed.

[0013] 2. It reduces the workload of operators, further lowers labor costs, and further improves the efficiency of the automatic painting system. After adjusting the automatic painting system, operators no longer need to wait in the painting room, reducing their prolonged exposure to paint fumes and improving the safety of the automatic painting system. Attached Figure Description

[0015] Figure 2 This is a structural diagram of an embodiment of the power transmission device. Detailed Implementation

[0016] See Figure 1 The tilting rotor mirror blade automatic painting device includes a base 1, a support 2, a right painting arm 3, a motor 4, a transmission device 5, a left synchronization mechanism 6, a right synchronization mechanism 7, a left painting arm 8, a right spray head 9, and a left spray head 10.

[0017] The motor 4 is located inside the base 1, which also includes a transmission device 5. The top of the base 1 has a support seat 2, in which a synchronization mechanism is installed. In this example, the left synchronization mechanism 6 and the right synchronization mechanism 7 are used to rotate synchronously. Both are gears of the same size and mesh externally.

[0018] The left synchronization mechanism 6 controls the position of the left spray painting arm 8, and the right synchronization mechanism 7 controls the position of the right spray painting arm 3. The left spray painting arm 8 has a left nozzle 10, and the right spray painting arm 3 has a right nozzle 9. After the motor 4 is started, the painting equipment begins to spray paint according to the planned path. Both the left and right rotating blades are in fixed positions, and their rotation positions meet the spraying space requirements of the left and right rotating blades.

[0019] See Figure 2 The synchronization mechanism adopts a mirror-driven power transmission method.

[0020] When painting, start motor 4, and the painting equipment will start painting synchronously according to the planned path. Both the left and right rotating blades are in fixed positions, and their rotation positions meet the spraying space of the left and right rotating blades.
