Description

Technical Field

[0001] This utility model relates to the field of auxiliary technology for CNC milling machines, specifically a powerful dust scraper ring that is easy to clean. Background Technology

[0002] CNC milling machines are automated machining equipment developed from general milling machines. The machining processes of the two are basically the same, and their structures are also somewhat similar. CNC milling machines are divided into two main categories: those without a tool magazine and those with a tool magazine. CNC milling machines with a tool magazine are also called machining centers. CNC milling machines come in various forms. Although different types of CNC milling machines differ in their composition, they have many similarities. The motion control center of the CNC milling machine executes the CNC machining program and controls the machine tool to perform machining.

[0003] Since the dust scraper ring is installed inside the front cover and fixed by a pressure plate, and the pressure plate is usually installed and removed using screws, it is necessary to disassemble and reinstall the dust scraper ring when cleaning is required, which is not very convenient. Therefore, those skilled in the art have provided a powerful dust scraper ring that is easy to clean in order to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a powerful dust scraper ring that is easy to clean, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A powerful dust scraper ring that is easy to clean includes a front cover. The front cover has an internal mounting tube. The inner wall of the mounting tube has a first mounting groove and a second mounting groove. A dust scraper ring body is mounted on the inner wall of the first mounting groove, and a U-shaped ring is mounted on the inner wall of the second mounting groove. A sealing shell is threaded to the outer surface of the mounting tube. The outer surface of the sealing shell is threaded to the inner wall of the front cover. A pressure plate is provided on the left side of the mounting tube, and the right side of the pressure plate contacts the left side of the sealing shell.

[0007] As a further improvement of this utility model: two slots are provided on the outer surface of the front cover, and an O-ring is engaged inside each slot.

[0008] As a further improvement of this utility model: a bearing is fixedly installed on the inner wall of the front cover, and the bearing is located at the right end of the front cover.

[0009] As a further improvement of this utility model: the outer surface of the front cover is provided with an opening, and the transverse cross-section of the opening is L-shaped.

[0010] As a further improvement of this utility model: two flat-head screw holes are provided on the left side of the pressure plate, and a flat-head screw is inserted through the inner wall of each flat-head screw hole.

[0011] As a further improvement of this utility model: two screw holes are provided on the left side of the closed shell, the outer surface of each flat-head screw passes through the mounting tube, and the right end of the flat-head screw is located in the screw hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model comprises a front cover, an installation tube, a first installation groove, a second installation groove, a dust scraper ring, a U-shaped ring, a sealing shell, and a pressure plate. The sealing shell seals the dust scraper ring and the U-shaped ring on the installation tube. The pressure plate, installation tube, and sealing shell can be disassembled as a whole, and the sealing shell can be easily disassembled by threads. This achieves the purpose of conveniently removing or installing the dust scraper ring and the U-shaped ring after overall disassembly, avoiding the need to remove the pressure plate before removing or placing the dust scraper ring and the U-shaped ring.

[0019] Please see Figure 1-4A powerful dust scraper ring that is easy to clean includes a front cover 1. The front cover 1 has an installation tube 8 inside. The inner wall of the installation tube 8 has a first installation groove 11 and a second installation groove 14. The inner wall of the first installation groove 11 is fitted with a dust scraper ring body 13, and the inner wall of the second installation groove 14 is fitted with a U-shaped ring 12. The outer surface of the installation tube 8 is threadedly connected to a sealing shell 10. The outer surface of the sealing shell 10 is threadedly connected to the inner wall of the front cover 1. A pressure plate 2 is provided on the left side of the installation tube 8, and the right side of the pressure plate 2 is in contact with the left side of the sealing shell 10.

[0020] Two slots 5 are provided on the outer surface of the front cover 1. An O-ring 6 is inserted into the interior of each slot 5. The slots 5 are used for the installation of the O-ring 6, and the O-ring 6 can fasten or seal the front cover 1. A bearing 7 is fixedly installed on the inner wall of the front cover 1, and the bearing 7 is located at the right end of the front cover 1. An opening 4 is provided on the outer surface of the front cover 1, and the transverse cross section of the opening 4 is L-shaped. The bearing 7 supports the rotation and helps to reduce the wear generated when the inner shaft of the bearing 7 rotates.

[0021] Two flat-head threaded holes 15 are provided on the left side of the pressure plate 2. A flat-head screw 3 is inserted through the inner wall of each flat-head threaded hole 15. The flat-head threaded hole 15 and the flat-head screw 3 are used to connect the pressure plate 2 and the mounting tube 8 to fix the pressure plate 2. Two screw holes 9 are provided on the left side of the closed shell 10. The outer surface of each flat-head screw 3 passes through the mounting tube 8, and the right end of the flat-head screw 3 is located in the screw hole 9. The screw hole 9 is used for positioning the flat-head threaded hole 15. The flat-head screw 3 is not inserted into the screw hole 9, thereby avoiding the flat-head screw 3 from affecting the rotation of the closed shell 10.

[0022] The working principle of this utility model is as follows: When using the front cover 1, the pressure plate 2, the mounting tube 8, and the sealing shell 10 are installed as a whole inside the front cover 1. The bearing 7 and the O-ring 6 are installed on the front cover 1 in fixed positions. The dust scraper ring 13 and the U-ring 12 are respectively installed in the first mounting groove 11 and the second mounting groove 14. The sealing shell 10, in conjunction with the mounting tube 8, seals and fixes the dust scraper ring 13 and the U-ring 12. Since the dust scraper ring 13 and the U-ring 12 need to be cleaned of dust and other contaminants after long-term use, the dust scraping function is guaranteed. For normal use of the ring body 13 and U-shaped ring 12, to avoid disassembling the flat-head screw 3 and pressure plate 2, the entire assembly consisting of pressure plate 2, mounting tube 8 and sealing shell 10 can be directly removed. Then, unscrew the sealing shell 10 from the mounting tube 8 and remove the dust scraper ring body 13 and U-shaped ring 12 directly from the right side of the mounting tube 8. After cleaning, install the dust scraper ring body 13 and U-shaped ring 12 in their original positions, screw on the sealing shell 10, and then insert the pressure plate 2, mounting tube 8 and sealing shell 10 into the front cover 1 as a whole. This makes overall disassembly, cleaning and replacement more convenient.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
