Description

Technical Field

[0001] This utility model relates to a polishing machine, and more particularly to a high-pressure cleaning nozzle device for a polishing machine. Background Technology

[0002] In automated double-sided polishing equipment, in order to improve the processing quality of parts, the surfaces of the upper and lower polishing discs need to be cleaned and rinsed after a period of processing. The previous solution used two sets of shower head-like devices. When it is necessary to clean the upper and lower discs of the double-sided polishing equipment, this device needs to be placed in the middle of the upper and lower discs of the double-sided polishing machine, with one set of nozzles facing upwards and the other set facing downwards. Using atmospheric pressure water, the shower head sprays water jets. The cleaning drive device of the double-sided polishing machine drives the two sets of shower head-like devices to move repeatedly from the inner circle to the outer circle of the upper and lower discs of the polishing machine, thereby achieving the cleaning and rinsing of the surfaces of the upper and lower polishing discs.

[0003] The technical problems with this structure are that, due to its inability to withstand high pressure, high-pressure water cannot be used, and the water jet pressure is insufficient, resulting in incomplete cleaning of the polishing disc surface. Furthermore, the use of two sets of spray nozzles requires two sets of branch supply pipelines, leading to structural complexity, increased weight, and difficulties in maintenance, resulting in long downtime. For modern mass production, high-speed and efficient processing, reducing auxiliary and downtime time is crucial for improving economic efficiency. Therefore, developing a spray nozzle device that meets the requirements of high-pressure spraying and incorporates a brushing structure to achieve simultaneous rinsing and brushing, thereby solving the high-quality rinsing and cleaning requirements of double-sided polishing equipment for both upper and lower polishing discs, while simplifying the overall structure, reducing weight, and making the mechanism easier to maintain, has become a pressing technical problem for those skilled in the art.

The lower end face of the 4 and the upper end face of the upper high-pressure guide shaft 8 are sealed, and the lower end face of the upper high-pressure guide shaft 8 and the intermediate support block 10 are sealed. The upper and lower sealing grooves of the lower high-pressure guide shaft 13 are respectively provided with a middle second sealing ring 12 and a lower nozzle sealing ring 15, which are used to seal the upper end face of the lower high-pressure nozzle 17 and the lower end face of the lower high-pressure guide shaft 13, and to seal the lower end face of the lower high-pressure guide shaft 13 and the intermediate support block 10, respectively.

The drive assembly is a structural component of the double-sided polishing machine. This high-pressure cleaning nozzle device moves repeatedly from the inner to the outer ring of the upper and lower plates of the polishing machine. While the upper and lower nozzles spray high-pressure water to rinse the upper and lower plates, the upper and lower plate-type brushes clean and scrub the upper and lower plates at the same time, which greatly improves the cleaning effect. At the same time, since most parts are made of lightweight, high-strength, and high-pressure resistant polyetheretherketone (PEEK) and acrylic materials, the weight of the entire device is greatly reduced while ensuring the high pressure resistance and high strength of the entire structure. This makes installation and maintenance convenient and greatly shortens the downtime for maintenance.
