Description

Technical Field

[0001] This utility model relates to the field of avionics equipment testing technology, specifically to an end effector for automatic testing of aviation control box products. Background Technology

[0002] The aircraft cockpit control panel contains multiple control boxes, such as status control boxes and setpoint control boxes. These control boxes vary in type and function, resulting in different panel layouts and switch / button types. During product testing, different buttons and knobs need to be pressed, rotated, and toggled up and down. Considering economy and practicality, an end effector needs to be designed to adapt to and perform various switch presses and knob rotations. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model proposes an end effector for automatic testing of aviation control box products. It achieves adaptability to different scenarios and solves the problems of end effectors being unable to perform various operations such as buttons, switches, and knobs, as well as the problem of actuators damaging the panels of aviation products during operation.

[0004] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0005] An end effector for automated testing of aircraft control box products includes two symmetrically distributed actuator arms, each actuator arm comprising:

[0006] The actuator base is connected to the controller on the robotic arm via screws;

[0007] The middle part of the actuator is connected to the actuator base;

[0008] The actuator end is connected to the middle part of the actuator. The actuator end adopts a flat cut design and the end is rounded.

[0009] As a further improvement of this utility model, the actuator base and the middle part of the actuator are an integral structure.

[0010] As a further improvement of this utility model, the actuator base and the middle part of the actuator are made of aluminum.

[0011] As a further improvement of this utility model, the actuators on the two actuator arms have a Y-shaped structure in the middle.

[0012] As a further improvement of this utility model, the actuator end is made of silicone material.

[0013] The beneficial effects of this utility model are:

[0014] Compared with existing end effectors, this invention breaks through the limitations of existing end effector fixtures. Through material selection and shape design, it achieves an end effector structure that can adapt to various aviation control box knobs, buttons, and switches, allowing for different degrees of opening and closing. Furthermore, while ensuring the normal operation of buttons and switches, a mirror-symmetric design is adopted to better fit the beak-shaped knob on the control box, achieving adaptability to different scenarios required for testing various control boxes. This ensures reliable operation of different button, knob, and switch pressing, rotating, and tossing operations, improving the efficiency and reliability of control box testing. To protect the appearance of the control box, silicone is added to the contact area between the actuator and the knob, avoiding the risk of damage to the control box product during operation.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figures 1 to 2 As shown, an end effector for automatic testing of aviation control box products includes two actuator arms. In order to better fit with the beak-shaped knob on the control box and improve the accuracy of operation, the actuator arms are used to rotate the knob. In addition to meeting the requirements of other switches and knobs, the two actuator arms are mirror-symmetrical in shape to match the shape of the beak-shaped knob.

[0021] Both actuator arms include an actuator base 1, an actuator middle section 2, and an actuator end section 3. The actuator base 1 and the actuator middle section 2 are an integral structure made of aluminum, which reduces their weight and lessens the precision burden on the robotic arm.

[0022] The actuator base 1 is securely and reliably connected to the controller of the robotic arm via screws. The actuator middle section 2, considering force application and coordination with various buttons on the control box, adopts a Y-shaped design. Different degrees of opening and closing allow for the execution of various switches and knobs, ensuring both actuator stability and the quality of its movements.

[0023] To ensure that the actuator end 3 can perform the pressing action with the button on the control box, a flat-cut design is adopted. Finally, to prevent scratches and damage to the appearance of the knobs and buttons of the aviation product, the end is rounded on the flat-cut basis. In addition, silicone is used in the part of the original aluminum actuator that contacts the switch to reduce damage to the product and protect the appearance of the product during product testing.

[0024] Working principle and usage process of this utility model:

[0025] In use, the following actions are taken: Switch up: The actuator end 3 closes and clamps the switch, forming a seamless, supportive platform, simulating the action of a finger to flick the switch up and down; Hook-shaped knob: The actuator end 3's mirror-symmetrical design perfectly matches the hook-shaped knob, accurately and forcefully clamping it for rotation; Control box button: After the actuator end 3 closes, the button is pressed.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
