Description

Technical Field

[0001] The present invention relates to the field of cleaning, in particular to a special high-pressure cleaning machine for deep and curved holes of automobile parts. Background Art

[0002] In the automotive manufacturing sector, the cleanliness of parts has a crucial impact on the performance, reliability, and service life of the vehicle, especially for auto parts with deep, curved hole structures. The internal channels are difficult to clean. Traditionally, the cleaning of auto parts mainly adopts manual cleaning and simple spray cleaning methods. Manual cleaning relies on manual operation, and workers use brushes, detergents and other tools to wipe the parts. This method is extremely inefficient. For deep-hole curved hole parts, due to the narrow and curved channels, it is difficult for manual labor to reach deep inside, and the cleaning effect is greatly reduced. The cleanliness of the internal parts cannot be guaranteed. Moreover, the quality stability of manual cleaning is poor, and the operating proficiency and cleaning intensity of different workers vary, making it difficult to meet the needs of large-scale, standardized automobile production. With the development of technology, spray cleaning has gradually been applied. Spray cleaning sprays cleaning fluid onto parts through a nozzle, using the impact force of the cleaning fluid to remove surface dirt. However, this method is still not ideal for cleaning parts with deep holes and curved holes. The special structure of deep holes and curved holes makes it difficult for the cleaning fluid to fully enter and cover the entire inner wall of the hole. Some areas are prone to forming cleaning dead corners, resulting in serious dirt residue. In addition, the pressure and flow rate of spray cleaning are difficult to accurately adjust according to the specific structure and cleaning requirements of the part. When cleaning some precision parts, excessive pressure may damage the parts, or insufficient pressure may fail to effectively remove dirt. With the rapid development of the automotive industry, the design of automotive parts is becoming more and more complex. Deep hole and curved hole structures are widely used in key components such as engine cylinders, crankshafts, and fuel injectors. The internal cleanliness of these holes is directly related to the vehicle's power performance, fuel economy, and emission indicators. If the deep hole and curved hole of the engine cylinder are not cleaned thoroughly, the residual dirt will affect the circulation of the engine oil, resulting in poor engine lubrication, increased wear, and reduced engine life. The blockage of the fuel injector hole will affect the fuel injection effect, resulting in incomplete fuel combustion, increased fuel consumption and exhaust emissions.

[0003] Therefore, those skilled in the art are committed to providing a special high-pressure cleaning machine for deep and curved holes of automobile parts that can effectively solve the above-mentioned technical problems. Summary of the Invention

[0039] The optimal working principle of the present invention is as follows: The automobile parts to be cleaned are placed on the positioning plate 17 of the positioning assembly 3. Several limiting openings 18 opened on the positioning plate 17 are used to preliminarily position the parts. The pneumatic clamping members 19 at the edge of the limiting openings 18 are started to clamp and fix the automobile parts to be cleaned, ensuring that the position of the parts is stable during the cleaning process; the rotation drive assembly 5 starts to work, which includes two positioning seats 13.

The columns 22 are connected by a connecting mechanism 23. An adjustment beam 27 is provided below the crossbeam 26 of the connecting mechanism 23.

The output end of the displacement motor 29 is rotatably connected to a support base 30 and is fitted with a drive gear 31.

The cleaning machine 6 is equipped with an extended cleaning nozzle 8. When the cleaning machine 6 is moved to the appropriate position, the cleaning machine 6 is started, and the high-pressure water pump generates a high-pressure water flow, which is used to flush the deep and curved holes of the automotive parts through the extended cleaning nozzle 8. At the same time, a number of water spray heads 21 installed on the water inlet pipe 20 between the inner wall of the cleaning chamber 2 and the positioning assembly 3 also spray water, assisting in cleaning the parts from different angles and improving the cleaning effect. The main control system module receives commands from the user interaction module and sends speed control signals to the rotary drive assembly 5 to adjust the rotation speed of components.

The motion control module receives motion commands from the main control system and controls the rotary drive assembly's drive motor 16, the displacement adjustment assembly's side seat power source, the displacement motor 29, and the cylinder 35 to ensure that all components move as instructed. The pressure and flow control module receives cleaning parameters from the main control system, adjusts the pressure of the high-pressure water pump of the cleaning machine 6, and controls the flow control valve of the water inlet pipe 20. Dynamically adjusts the cleaning pressure and flow rate based on the material and channel characteristics of different components to avoid damage to the workpiece. The condition monitoring module collects current, temperature, and speed data from the drive motor 16, position feedback signals from the displacement motor 29, air pressure and stroke of the cylinder 35, pressure sensor data from the pneumatic clamp 19, and data from the water level sensor and water quality sensor in the cleaning chamber 2, and transmits this data to the main control system module. If the condition monitoring module detects abnormal data, the fault diagnosis and safety module receives the data and sends an emergency shutdown signal to the main control system, triggering the audible and visual alarm device and recording the fault log in the storage module. The user interaction module allows operators to send operating instructions to the main control system, display data from the condition monitoring module, present fault diagnosis information, and interact with the storage module to query historical records. The storage and data analysis module stores condition monitoring data, cleaning program parameters, operation logs, and fault information, providing historical data to the data analysis engine to facilitate analysis and optimization of equipment operation. The communication module supports industrial Ethernet communication with the host computer for remote monitoring connection and reserves a data interface with the MES system to facilitate integration with the factory production management system.
