Description

Technical Field

[0001] This utility model relates to the field of ball bearing guide technology, specifically a stable moving ball bearing guide. Background Technology

[0002] Ball bearing guides are a type of rolling guide. They consist of steel balls that roll infinitely between a slider and a rail, allowing the load platform to easily move linearly with high precision along the rail. Their coefficient of friction can be reduced to 1 / 50 of that of traditional sliding guides, enabling them to easily achieve micron-level positioning accuracy.

[0003] According to application number CN201820151587.X, a miniature ball linear guide is disclosed, including a guide body. A slider is provided on the top side of the guide body, and a motor cavity is opened on the slider. A motor is fixedly installed in the motor cavity. Through holes are opened on both sides of the inner wall of the motor cavity. A slide rod is slidably installed in the through holes. A threaded groove is opened at the end of the slide rod near the motor cavity. A threaded block is installed in the threaded groove. A rotating shaft is fixedly installed on the side of the threaded block near the motor. The end of the rotating shaft near the motor extends into the motor cavity and is fixedly connected to the output shaft of the motor. The end of the slide rod away from the motor cavity extends out of the through hole and is fixedly connected to a fixing block. The two fixing blocks are slidably connected to both sides of the guide body. A sliding groove is opened on both sides of the guide body. A first ball groove is opened on the side of the fixing block near the guide body. A first ball is rotatably installed in the first ball groove.

[0004] The ball bearing guides in the above cases do not have a dust removal effect. Because the workpiece generates a large amount of corrosive dust and fumes during processing, dust and impurities will adhere to the ball bearing guides during use. When the balls roll on the guides, the balls come into contact with the dust, which will aggravate the wear of the balls, affect the smoothness and accuracy of the ball bearing guide's motion transmission, increase the generation of abnormal noises during use, and greatly shorten the service life of the ball bearing guides. Therefore, we provide a stable moving ball bearing guide. Utility Model Content

At the same time, it is convenient to remove the recess 3 from the sliding plate 2 later, so as to facilitate the maintenance and repair of the structure on the recess 3.

[0027] It also includes a fixed shell 6, of which there are two, and each is installed on the top of a two recess 3. A suction pump 7 is fixedly connected to the top of the fixed shell 6. The suction pipe at the bottom of the suction pump 7 passes through the fixed shell 6 and extends into its interior. A pluggable filter screen 8 is provided inside the fixed shell 6. The surface of the filter screen 8 is in contact with the inner wall of the fixed shell 6. Fixing blocks 9 are fixedly connected to the left and right sides of the inner wall of the fixed shell 6, at the top and bottom of the filter screen 8. The side of the fixing block 9 closest to the filter screen 8 is in contact with the filter screen 8. Connectors 10 are fixedly connected to the left and right sides of the recess 3. The top of the connector 10 is connected to the fixed shell 6 through a fixing pipe 11. Connecting pipes 12 are fixedly connected to the front and back of the connector 10 and are connected to them.

[0031] Specifically, loosen the fixing bolt 23, then pull the recessed block 3. The recessed block 3 moves away from the sliding plate 2. The recessed block 3 drives the insert block 19 to be pulled out of the slot 20, so that the limiting block 21 is pulled out of the limiting groove 22. This allows the recessed block 3 to be pulled forward or backward from the guide rail body 1, thus allowing maintenance of the structure on the recessed block 3. Loosen the fastening bolt 18, then push the rubber scraper 4. The rubber scraper 4 drives the mounting block 14 to move closer to the limiting block 21. The mounting block 14 drives the positioning groove 16 to move closer to the limiting block 21, so that the positioning groove 16 and the positioning block 17 separate, thus completing the disassembly. The distance between the suction head 5 and the rubber scraper 4 can ensure that the rubber scraper 4 has space for disassembly and assembly.

[0032] The components 3 (recessed block), 4 (rubber scraper), 5 (suction head), 6 (fixed shell), 7 (air pump), 8 (filter), 9 (fixed block), 10 (connector), 11 (fixed pipe), 12 (connecting pipe), 13 (reinforcing block), 14 (mounting block), and 15 (stabilizing block) work together to facilitate dust removal from the guide rail body 1. This prevents the balls from coming into contact with dust and impurities while rolling on the guide rail, thus reducing wear and ensuring the stability of the balls' movement. It also reduces abnormal noise caused by dust and impurities, thereby improving the service life of the ball bearing guide rail. The rubber scraper 4 can scrape away impurities and dust on both sides of the guide rail, and the suction head 5 can remove dust and impurities from both sides of the guide rail, improving practicality.

[0033] In use, the sliding plate 2 is activated by an external device, causing the sliding plate 2 to drive the ball bearing body 101 to roll on the guide rail body 1. The sliding plate 2 drives the concave block 3 to move forward or to the right. The concave block 3 drives the rubber scraper 4 to scrape away dust and impurities on the left and right sides of the guide rail body 1. The air pump 7 is activated, which creates negative pressure inside the fixed shell 6. Through the fixed pipe 11, connector 10 and connecting pipe 12, the suction head 5 generates suction, sucking the dust and impurities on the left and right sides of the guide rail body 1 into the fixed shell 6, where they are intercepted by the filter screen 8.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
