Description

Technical Field

[0001] The utility model relates to the technical field of aerospace manufacturing, in particular to a skin standardized chamfering tool. Background Art

[0002] Aircraft skin chamfering technology is one of the key technologies in the field of aviation manufacturing. It directly affects the aerodynamics, stealth performance and structural strength of the aircraft. With the development of the aviation industry, the requirements for the accuracy and efficiency of aircraft skin chamfering are getting higher and higher. At present, the technical solutions for aircraft skin chamfering mainly include the following two methods:

[0003] - Pre-assembly chamfering: In this method, the skin is pre-assembled, then the step difference is measured and marked. After that, the skin is removed and chamfered according to the mark using a grinding tool.

[0004] -Chamfering immediately after assembly: In this method, after the skin is assembled, the worker feels the step difference by hand, and then immediately performs manual chamfering based on experience.

[0005] Although the above methods can achieve good chamfering effects, there are still some problems and shortcomings. For example, the pre-assembly chamfering method has low assembly efficiency due to multiple disassembly, and it is difficult to ensure the consistency and accuracy of the chamfering; while the immediate chamfering method after assembly can respond quickly, it is overly dependent on the workers' experience and feelings, prone to human errors, and is not suitable for newcomers. In addition, these two methods may cause damage to the skin during operation, affecting the overall performance of the aircraft. Utility Model Content

[0006] 1. Technical issues to be resolved

[0007] In view of this, the purpose of the utility model is to propose a standardized chamfering tool for skin, which can accurately chamfer the step difference between aircraft skins without multiple disassembly and reassembly. At the same time, it can automatically adjust according to the ups and downs of the skin, thereby ensuring the consistency and accuracy of the chamfer and reducing the damage to the skin, so as to solve the problems of low efficiency of multiple assemblies in the prior art and the inability to follow up, which may cause damage to the skin and affect the overall performance of the aircraft.

[0008] (II) Technical solution

[0009] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0010] A standardized chamfering tool for skin includes a chamferer and a right-angle stopper. The right-angle stopper includes a horizontal plate and a vertical plate integrally arranged on the horizontal plate and perpendicular to the horizontal plate. The vertical plate is perpendicular to the axis of the chamferer.

[0011] Furthermore, the chamfering device includes a grinding head and an electric motor or a pneumatic motor for driving the grinding head, and the grinding head is fixed on a main shaft of the electric motor or the pneumatic motor.

[0012] Furthermore, the horizontal plate is detachably fixed to the bottom of the electric motor or the pneumatic motor.

[0013] Furthermore, arc-shaped pinching blocks for easy hand holding are arranged on the left and right sides of the electric motor or the pneumatic motor.

[0014] Furthermore, the vertical plate includes at least one abutment plate for inserting into the gap of the skin, and the abutment plates are arranged in parallel and have the same horizontal distance with the grinding head.

[0015] Beneficial Effects

[0016] The utility model uses a right-angle stopper to limit the position, and then uses a chamfering device to perform the chamfering operation. Since the distance between the right-angle stopper and the chamfering device is relatively constant, the chamfering removal amount is always consistent, and it can be kept perpendicular to the shape at any time as the right-angle stopper moves, so as to always maintain the same cutting amount. Compared with the prior art, it has the following advantages:

[0017] 1. Improved accuracy: The right-angle stopper and integrated reference plate design can accurately align and make the grinding head perpendicular to the skin gap, ensuring the consistency and accuracy of the chamfering work. This has higher accuracy than the traditional pre-assembly chamfering and immediate chamfering after assembly methods.

[0018] 2. Improve efficiency: Due to the simplicity of tool design, the operator can directly pinch the shape on both sides of the motor for operation without the need for a special push handle, which simplifies product design content and operation process and greatly improves the efficiency of chamfering work.

[0019] 3. Reduce damage: In traditional chamfering methods, manual grinding can easily cause damage to the skin, affecting the overall performance of the aircraft. The utility model greatly reduces the potential damage to the skin by precisely controlling the position and pressure of the grinding head.

[0020] 4. Strong adaptability: The utility model can adapt to the gaps of skins of different thicknesses, and the grinding head can be replaced with different shapes and sizes as needed, making the tool highly adaptable.

[0021] 5. Easy to operate: The miniaturized design of the tool makes it easier to operate, especially in space-constrained environments, providing a better operating experience.

[0022] 6. Improved safety: Since this tool can be designed to be lightweight and miniaturized, the tool cost is greatly reduced, the safety risks caused by high-power tools in manual operations are reduced, and the safety of the working environment is improved.

[0023] In general, compared with the prior art, the utility model provides a more accurate, efficient, economical and safe solution for chamfering aircraft skins, which can effectively improve the quality and efficiency of the production process of the aviation manufacturing industry. These advantages and positive effects directly correspond to the shortcomings of the prior art and the purpose of the utility model, demonstrating the significant advantages of the utility model in practical applications.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] like Figure 1-4 As shown, the present embodiment provides a standardized chamfering tool 1 for skin, including a chamferer 2 and a right-angle limiter 3. The chamferer of the present embodiment includes a grinding head 4 and a driving motor 5. The driving motor is used to drive the grinding head to rotate for chamfering operation, and can be an electric motor or a pneumatic motor. The grinding head is removably fixed on the main shaft of the electric motor or the pneumatic motor. The right-angle limiter of the present embodiment includes a horizontal plate 7 and a vertical plate 8. The horizontal plate is fixed to the bottom of the motor, or is parallel to the bottom of the motor and fixed on one side of the main shaft. The vertical plate is integrally arranged on the horizontal plate and is perpendicular to the horizontal plate to form a right-angle shape. When fixed, the vertical plate is perpendicular to the axis of the grinding head, so that the horizontal plate is parallel to the axis of the grinding head. When the horizontal plate moves horizontally, the grinding head moves at the same time and performs chamfering operation. At this time, the vertical plate always rests on the side of the skin 6, and its spatial position and direction are consistent with the chamfered skin, thereby ensuring the consistency and accuracy of the chamfering.

[0031] In this embodiment, arc-shaped pinching blocks 7 are provided on the left and right sides of the electric motor or the pneumatic motor, which facilitate the operator to hold the motor with his hands, making the holding reliable and labor-saving, and preventing fatigue during long-term moving operations.

[0032] In this embodiment, the vertical plate includes at least one abutment plate 9. In this embodiment, two abutment plates are provided in total. The two abutment plates are parallel and spaced apart, that is, in the horizontal direction, the two abutment plates are at the same horizontal distance from the grinding head, so that they can be inserted into the gap of the skin and abut against the side of the skin at the same time. Since two plates are provided, the action is smooth and the force is balanced, making the operation easier and more labor-saving.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
