Description

Technical Field

[0001] The invention belongs to the technical field of aircraft parts repair, and in particular relates to automatic glue removal equipment for sealing gasket components. Background Art

[0002] The sealing gasket assembly is an important sealing component on the aircraft combined transmission power generation device and constant speed transmission device. The component has a complex structure, difficult process and high cost. The method usually adopted during aircraft maintenance operations is to manually remove the glue and then refurbish it for use.

[0003] The traditional method of removing rubber is to manually use a flat-blade screwdriver to scrape off the rubber. This method not only fails to completely remove the residual rubber, but also easily damages the bottom and side surfaces of the metal frame glue pressing groove of the combined sealing gasket, resulting in high labor intensity and low production efficiency. Summary of the invention

[0004] In view of the above problems, the present invention provides an automatic degumming device for sealing gasket assemblies, which can remove the glue from the repaired sealing gasket assemblies, improve the cleaning efficiency, realize unmanned intelligent operation, and protect the surface of the sealing gasket skeleton at the same time.

[0005] The technical solution of the present invention is: an automatic glue removal device for a sealing gasket assembly, comprising a driving system, a power transmission system, a control handle, a displacement trolley and a light-controlled sensing device; The driving system includes a motor, the main shaft of which is connected to an elastic outer sleeve; The power transmission system comprises a flexible shaft, one end of which is connected to the main shaft of the driving system through an elastic sleeve, and the other end of which is connected to a control handle, so that power can be transmitted from the main shaft to the control handle; The control handle is connected to the rear end of the displacement trolley, and a clamping nozzle is installed at the front end of the displacement trolley. The transmission shaft of the control handle is connected to the clamping nozzle, and an annular copper brush is installed on the clamping nozzle. Power is transmitted to the clamping nozzle through the transmission shaft in the control handle, thereby driving the annular copper brush to rotate; the displacement trolley is mainly composed of a micro motor and wheels, and its function is to drag the annular copper brush to move.

[0006] The annular copper brush is composed of a plurality of long copper needles and long fiber bundles arranged in rows and staggered, and the angle between the long copper needles and the long fiber bundles and the horizontal direction is 30° to 60°; in addition, short copper needles and short fiber bundles are arranged at the edge of the annular copper brush. The copper needles are mainly used to dig out rubber, and the main function of the fiber bundles is to sweep away residual rubber and clean the surface of the sealing gasket assembly; the angle between the short copper needles and the short fiber bundles at the edge of the annular copper brush can effectively clean the rubber in the dead corners of the sealing gasket assembly.

[0007] Furthermore, the annular copper brush is composed of a central guide column, an annular roller, long copper needles, short copper needles, long fiber bundles and short fiber bundles; the central guide column and the annular roller are fixedly connected, and the surface of the annular roller has many holes of different sizes for implanting and fixing long and short copper needles and long and short fiber bundles.

[0008] The light-controlled sensing device is arranged at the front of the displacement cart and is mainly composed of a transmitter and a receiver. The position of the object is determined by the time difference between the sent and received light signals, and sub-micron level precision position control can be obtained, which is used to control the moving path of the cart, thereby achieving efficient and accurate cleaning.

[0009] Furthermore, the tips of the long copper needle and the short copper needle are sheet-shaped blades, and the copper needle is made of copper material with a lower hardness than the metal skeleton of the sealing gasket.

[0010] Furthermore, the drive system includes a metal base, on which a motor is mounted. The motor obtains energy from a battery or a wire plug, one end of the motor is equipped with a secondary switch button with an indicator light, and the other end of the motor drives the main shaft to rotate. The metal base is also equipped with a power switch, a power indicator light, a speed knob and a working indicator light for controlling and monitoring the working status of the drive system.

[0011] Furthermore, the driving system can be connected to a power source through a wire plug of the metal base to work, and can also be detached from the metal base and work independently by using energy provided by a battery.

[0012] The beneficial effects of the present invention are as follows: an automatic glue removal device is provided, which has a simple structure, is easy to operate, and has low labor costs. It can not only quickly clean the rubber in the groove of the sealing gasket component, but also greatly improve the glue removal efficiency. At the same time, the material hardness of the copper needles and fiber bundles selected by the present invention is lower than that of the metal skeleton of the sealing gasket, so the surface of the skeleton groove will not be scratched during cleaning, thereby effectively protecting the surface quality of the metal of the metal skeleton groove of the combined sealing gasket.
