Problems solved by technology

[0002] The existing surface cleaning method of the workpiece directly cleans the surface with high-pressure air or ultrasonic vibration water flow, but when the composite material workpiece (such as fiber reinforced composite material, etc.) requires dry cutting, especially when the surface structure of the workpiece is complex , the powdery chips generated during the cutting process will adhere to the surface of the workpiece, or even press into the surface of the workpiece
This makes it impossible to clean the surface with liquid ultrasonic waves, and it is difficult to deep clean the surface of the workpiece with special requirements through the above method

Embodiment 1

[0049] This embodiment discloses a composite material workpiece surface cleaning system, which includes an ultrasonic vibration device, a temperature control module, a cooling module, a control module and a high-pressure air jet device.

[0050] see figure 1 , the ultrasonic vibration device includes a loading platform 1 , an upper cover 2 , a box body 3 and an ultrasonic transducer 4 .

[0051] see image 3 , the lower end of the box body 3 is closed, and the upper end is open. The lower end of the box body 3 is fixed on a horizontal plane. The side wall of the box body 3 has a cooling gas inlet 301 and three heat exchange gas outlets 302 . The outlet area of ​​the heat exchange gas outlet 302 is denoted as S 1 , denote the inlet area of ​​the cooling gas inlet 301 as S 2 , S 2 / 61 2 / 3. The terminal II303 is also fixed on the side wall of the box body 3 .

[0052] There are four ultrasonic transducers 4, and the four ultrasonic transducers 4 are horizontally fixed in...

Embodiment 2

[0070] This embodiment provides a relatively basic implementation method, a composite material workpiece surface cleaning system, including an ultrasonic vibration device, a temperature control module, a cooling module, a control module and a high-pressure air jet device.

[0071] see figure 1 , the ultrasonic vibration device includes a loading platform 1 , an upper cover 2 , a box body 3 and an ultrasonic transducer 4 .

[0072] see image 3 , the lower end of the box body 3 is closed, and the upper end is open. The lower end of the box body 3 is fixed on a horizontal plane. The side wall of the box body 3 has a cooling gas inlet 301 and three heat exchange gas outlets 302 . The outlet area of ​​the heat exchange gas outlet 302 is denoted as S 1 , denote the inlet area of ​​the cooling gas inlet 301 as S 2 , S 2 / 61 2 / 3. The terminal II303 is also fixed on the side wall of the box body 3 .

[0073] There are four ultrasonic transducers 4, and the four ultrasonic tra...

Embodiment 3

[0087] The main structure of this embodiment is the same as that of Embodiment 2. Further, the lower end of the loading platform 1 is welded with a short external threaded rod, and the ultrasonic transducer 4 has an internal thread, and the loading platform 1 is connected to the ultrasonic transducer by a thread. On the device 4, the contact surface between the ultrasonic transducer 4 and the object-carrying platform 1 is coated with an adhesive, so that the ultrasonic transducer 4 and the object-carrying platform 1 are closely connected to ensure uniform ultrasonic transmission process.

Description

technical field [0001] The invention belongs to the field of workpiece surface cleaning, and in particular relates to a composite material workpiece surface cleaning system and method. Background technique [0002] The existing surface cleaning method of the workpiece directly cleans the surface with high-pressure air or ultrasonic vibration water flow, but when the composite material workpiece (such as fiber reinforced composite material, etc.) requires dry cutting, especially when the surface structure of the workpiece is complex , The powdery chips generated during the cutting process will adhere to the surface of the workpiece, or even press into the surface of the workpiece. This makes it impossible to clean the surface by liquid ultrasonic waves, and it is difficult to perform deep cleaning on the surface of workpieces with special requirements by the above method. [0003] Therefore, there is a need in the prior art for a composite material workpiece surface cleaning...
