[0002] During the cleaning process of the plasma cleaning machine, the inside of the plasma cleaning machine needs to be vacuumed. After vacuuming, the workpiece to be cleaned is cleaned using plasma technology. During the cleaning process, a lot of dust will be generated. Since the output shaft of the vacuum switching cylinder of the plasma machine is a smooth surface, the dust generated is more likely to adhere to the output shaft of the vacuum switching cylinder. After a period of dust adhesion, the dust will affect the smoothness of the output shaft of the vacuum switching cylinder on the one hand, and on the other hand, the dust will enter the interior of the vacuum switching cylinder, causing damage to the vacuum switching cylinder.

[0020] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.
[0021] Depend on Figures 1 to 5 A plasma machine vacuum switching cylinder protection structure is provided, including a fixed structure connected to the plasma machine vacuum switching cylinder and a protection component arranged on the fixed structure. The fixed structure is used to connect the protection component to the plasma machine vacuum switching cylinder, and the protection component is fixedly installed under the action of the fixed structure.
[0022] The protection component includes a powder scraper ring 1 that is connected to the output shaft of the vacuum switching cylinder. The inner edge of the powder scraper ring 1 is a conical surface that protrudes toward the output shaft of the vacuum switching cylinder. The conical surface of the powder scraper ring 1 scrapes away the dust on the outer edge of the output shaft of the vacuum switching cylinder. The powder scraper ring 1 is made of Teflon, a low-friction and highly wear-resistant plastic. At the same time, the outer edge of the output shaft of the vacuum switching cylinder is relatively smooth. Therefore, the setting of the conical surface can scrape away the dust on the output shaft of the vacuum switching cylinder.
[0023] A buffer ring 2 is coaxially provided between the powder scraper ring 1 and the fixed structure. The buffer ring 2 is connected to the powder scraper ring 1 via a spring 3. The buffer ring 2 supports the powder scraper ring 1 when the output shaft of the vacuum switching cylinder moves inside the vacuum switching cylinder. At the same time, under the action of the spring 3, a gap is created between the powder scraper ring 1 and the buffer ring 2 when the output shaft of the vacuum switching cylinder is in a stationary state, thereby preventing dust on the conical surface of the powder scraper ring 1 from leaking to the buffer ring 2 when the output shaft of the vacuum switching cylinder is in the next operation.
[0024] There is a gap between the inner edge surface of the buffer ring 2 and the output shaft of the vacuum switching cylinder. The inner edge surface of the buffer ring 2 does not contact the outer edge surface of the output shaft of the vacuum switching cylinder. On the one hand, it avoids interference with the output shaft of the vacuum switching cylinder, and on the other hand, it prevents the sealing oil on the output shaft of the vacuum switching cylinder from adhering to the buffer ring 2.
[0025] The fixing structure includes a fixing ring 4 connected to the vacuum switching cylinder and coaxial with the output shaft of the vacuum switching cylinder. Sealing oil is provided between the fixing ring 4 and the output shaft of the vacuum switching cylinder. The fixing ring 4 can be fixed to the vacuum switching cylinder by welding or one-time molding. The sealing oil is used to ensure the sealing between the fixing ring 4 and the output shaft of the vacuum switching cylinder on the one hand, and on the other hand, it is used to enable the output shaft of the vacuum switching cylinder to move relatively smoothly relative to the fixing ring 4.
[0026] The fixed structure also includes a support ring 5 connected to the fixed ring 4. The support ring 5 provides limited support for the buffer ring 2. The support ring 5 can be fixed to the fixed ring 4 by threaded connection, plug-in and welding. In order to better disassemble, the preferred connection method of the utility model is threaded connection. The support ring 5 fixes the position of the buffer ring 2. At the same time, the disassembly connection of the support ring 5 allows the buffer ring 2 and the scraper ring 1 to be replaced.
[0027] The powder scraper ring 1, the buffer ring 2 and the support ring 5 are connected by a stud 6. A nut 7 threadedly connected to the stud 6 is slidably connected inside the support ring 5. The nut 7 is connected to the support ring 5 via a compression spring 8. The stud 6 is used in conjunction with the nut 7 set in the support ring 5. Under the action of the stud 6 and the nut 7, the powder scraper ring 1, the buffer ring 2 and the support ring 5 are limited and guided. At the same time, the compression spring 8 is used in conjunction with the spring 3 so that when the output shaft of the vacuum switching cylinder is in action, the buffer ring 2 and the powder scraper ring 1 will not affect the operation of the vacuum switching cylinder.
[0028] The powder scraper ring 1 is provided with a countersunk hole 9 for accommodating the stud 6. The countersunk hole 9 is used to accommodate the head of the stud 6, so that one end of the powder scraper ring 1 is flat, preventing the stud 6 from interfering with the end of the vacuum switching cylinder.
[0029] When the present invention is in use, the staff sequentially installs the support ring 5, the buffer ring 2 and the powder scraping ring 1 on the output shaft of the vacuum switching cylinder, and uses threads to relatively fix the support ring 5 and the fixing ring 4. After the support ring 5 is fixed, the staff uses the stud 6 and the nut 7 to guide the buffer ring 2 and the powder scraping ring 1, and sets the spring 3 in a suitable position. When the output shaft of the vacuum switching cylinder moves toward the inside of the vacuum switching cylinder, the inner edge of the powder scraping ring 1 faces the output shaft of the vacuum switching cylinder to scrape off the dust, preventing the dust on the output shaft of the vacuum switching cylinder from entering the vacuum switching cylinder, thereby avoiding the dust from causing the output shaft of the vacuum switching cylinder to operate poorly.
[0030] The utility model utilizes a powder scraping ring and a conical surface provided on the inner edge of the powder scraping ring to protect the output shaft of the vacuum switching cylinder, thereby preventing dust on the output shaft of the vacuum switching cylinder from interfering with the operation of the output shaft of the vacuum switching cylinder.
[0031] The utility model adopts a disassembly structure of the support ring and the fixed ring, so that the powder scraping ring and the buffer ring can be disassembled and connected, so that the powder scraping ring and the buffer ring can be replaced after a period of use;
[0032] The utility model provides sealing oil between the fixing ring and the output shaft of the vacuum switching cylinder. Under the action of the sealing oil, the vacuum switching cylinder is kept in a sealed state, further isolating the dust. At the same time, the sealing oil can play a lubricating role, thereby making the output shaft of the vacuum switching cylinder operate better.
