DETAILED DESCRIPTION

[0027] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] like Figure 1-Figure 6As shown, the present invention provides a technical solution: a four-row single arc ball linear guide, including a guide body 1, a groove 2, a slider 3, a mounting block 4, a top plate 5, an oil plug cap 6, an oil pipe 7, a lubrication cavity 8, an annular groove 9, a retainer 10, a ball 11, a mounting hole 12, an auxiliary component 13, a metal baffle 1301, an oil scraper 1302, a metal baffle 2 1303, an oil absorption plate 1304, a mounting column 14, a connecting vertical plate 15, a transmission component 16, a transmission shaft 1601, a driving roller 1602, a conveyor belt 1603, a micro double-headed motor 17, a built-in column 18, a blade 19, an auxiliary component 20, a transmission bottom shaft 2001, a built-in column 2002, a blade 2003, an adjustment component 21, and an outer frame 21 01, built-in groove 2102, threaded column 2103, cleaning brush 2104, built-in frame 2105 and dust cover 22, grooves 2 are provided on both sides of the guide rail body 1, and an adjustment component 21 for cleaning the groove 2 is installed inside the groove 2, the adjustment component 21 includes an outer frame 2101, a built-in groove 2102, a threaded column 2103, a cleaning brush 2104 and a built-in frame 2105, and a built-in groove 2102 is provided inside the outer frame 2101, the built-in groove 2102 is rotatably installed inside the built-in frame 2105, and a threaded column 2103 is provided in the middle of one end of the built-in frame 2105, a built-in column 18 is threadedly installed on one end of the threaded column 2103, and the outer surface of the built-in column 18 is annularly distributed with blades 19 , a micro double-headed motor 17 is arranged outside one end of the built-in column 18, a cleaning brush 2104 is connected in an annular manner to the outer surface of one side of the built-in frame 2105, a slider 3 is arranged outside the guide rail body 1, and an annular groove 9 is opened on both sides of the slider 3, a ball 11 is installed inside the annular groove 9, and a retainer 10 is arranged outside the ball 11. The slider 3 starts from the starting position and moves to the target position along the curved trajectory of the groove 2 of the guide rail body 1 through the guiding effect of the guide rail body 1. In this process, the ball 11 inside the slider 3 rolls in the annular groove 9 and adjusts its own position as the shape of the guide rail body 1 changes. When the slider 3 moves along the position of the guide rail body 1, the design of the micro double-headed motor 17 can be utilized. The built-in column 18 and the blade 19 are driven to rotate, so that the blade 19 can rotate quickly. The rotation of the blade 19 can blow away the dust or other particles attached to the inside of the groove 2, so as to prevent dust from entering when the slider 3 moves along the outside of the groove 2, thereby affecting the rotation of the ball 11 inside the slider 3, and maintaining the accuracy of the ball 11 during rotation. The design of the threaded connection between the built-in column 18 and the threaded column 2103 facilitates the installation of the built-in frame 2105 connected to the threaded column 2103 inside the outer frame 2101, so that when the built-in column 18 rotates, the built-in frame 2105 can be driven to rotate inside the built-in groove 2102, and then the cleaning brush 2104 on the outer surface of the built-in frame 2105 will rotate due to the rotation of the built-in frame 2105.The cleaning brush 2104 is conveniently designed to be rotated to clean dust or other attachments attached to the outer surface of the groove 2, ensuring that the outer surface of the groove 2 is clean, and the cleaning brush 2104 can be self-cleaned by the rotation of the blade 19.

The lubricating oil liquid, the oil pipe 7 is connected with the lubrication chamber 8, and the lubrication chamber 8 is connected with the annular groove 9. The inertia and gravity when the slider 3 moves about the guide rail body 1 can make the lubricating oil liquid enter the annular groove 9 through the oil pipe 7 and the lubrication chamber 8, so that the ball 11 can contact with the lubricating oil liquid when it rotates in the annular groove 9, thereby achieving lubrication of the ball 11 when it rotates in the annular groove 9, avoiding the increase of friction resistance between the ball 11 and the annular groove 9 after multiple rotations, resulting in temperature increase and noise, and has a good stabilizing effect.

[0030] like Figure 2 , Figure 3 and Figure 5As shown, the bottom of the top plate 5 is equipped with two groups of auxiliary components 13 for auxiliary dust prevention and protection of the slider 3, and the auxiliary components 13 include a metal baffle 1301, an oil scraper 1302, a metal baffle 2 1303 and an oil absorption plate 1304, and the outer surface of the metal baffle 1301 is clamped and installed with the oil scraper 1302, one side of the oil scraper 1302 is provided with a metal baffle 2 1303, and the outer surface of one side of the metal baffle 2 1303 is installed with the oil absorption plate 1304, the metal baffle 1 1301 is provided with a mounting hole 12, the shape structure of the metal baffle 1 1301, the oil scraper 1302, the metal baffle 2 1303 and the oil absorption plate 1304 is consistent with the shape structure of the groove 2, and the metal baffle 1 1301 and The metal baffles 1303 are consistent in shape and size. When the slider 3 moves in accordance with the grooves 2 on both sides of the guide rail body 1, the metal baffles 1301 can be designed to be consistent with the shape and structure of the grooves 2, so that the slider 3 can slide stably while the metal baffles 1301 can be used to shield and protect the slider 3 from both sides. The scraper plate 1302 can be used to scrape off excess lubricating oil. The sponge-made oil absorption plate 1304 can also be used to absorb the residual lubricating oil, so as to keep the outer surface of the groove 2 clean and tidy, which is convenient for the stable use of the linear guide. The other output end of the micro double-headed motor 17 is equipped with a transmission assembly 16 for auxiliary transmission, and the transmission assembly 16 includes a transmission shaft 1601, a drive shaft 1602, a drive shaft 1603, a drive shaft 1604, a drive shaft 1605, a drive shaft 1606, a drive shaft 1607, a drive shaft 1608, a drive shaft 1609, a drive shaft 1610, a drive shaft 1611, a drive shaft 1612, a drive shaft 1613, a drive shaft 1614, a drive shaft 1615, a drive shaft 1616, a drive shaft 1617, a drive shaft 1618, a drive shaft 1619, a drive shaft 1620, a drive shaft 1630, a drive shaft 1640, a drive shaft 1650, a drive shaft 1661, a drive shaft 1670, a drive shaft 1680, a drive shaft 1690, a drive shaft 1691, a drive shaft 1692, a drive shaft 1693, a drive shaft 1694, a drive shaft 1695, A driving roller 1602 and a conveyor belt 1603, a driving roller 1602 is arranged at the end of the transmission shaft 1601, and a conveyor belt 1603 is installed on the outer surface of the driving roller 1602, a connecting vertical plate 15 is arranged at the end of the transmission shaft 1601, and a mounting column 14 is installed on the outer surface of one side of the connecting vertical plate 15, an auxiliary component 20 for cleaning the groove 2 is arranged at the bottom of the conveyor belt 1603, and the auxiliary component 20 includes a transmission bottom shaft 2001, a built-in column 2002 and a blade 2003, a built-in column 2002 is arranged at one end of the transmission bottom shaft 2001, and a blade 2003 is installed on the outer surface of the built-in column 2002, and the design of the micro double-headed motor 17 and the driving shaft can be used to clean a group of grooves 2 At the same time, the driving roller 1602 is driven to rotate synchronously. Through the rotation of the driving roller 1602 and the design of the conveyor belt 1603, the transmission bottom shaft 2001 and the built-in column 2 2002 can be driven to rotate, so that the built-in column 2 2002 and the blade 2 2003 can rotate synchronously, so that the upper and lower groups of grooves 2 can be cleaned synchronously to ensure that there is no dust attached to the outside of the guide rail body 1 when in use, to avoid dust, smoke and other impurities that affect the processing accuracy of the device, to avoid aging of internal components, and to extend the service life of the device. In addition, the mounting column 14 is installed in engagement with the mounting hole 12. Through the above installation, it is convenient to indirectly assemble the entire connecting vertical plate 15 and the slider 3, which is beneficial to the assembly and use of the entire cleaning and dust removal structure and the slider 3.

[0031] In summary, if Figure 1-Figure 6As shown, the four-row single arc ball linear guide, when in use, the slider 3 starts from the starting position and moves to the target position along the curved trajectory of the groove 2 of the guide rail body 1 through the guiding effect of the guide rail body 1. In this process, the ball 11 inside the slider 3 rolls in the annular groove 9 and adjusts its own position as the shape of the guide rail body 1 changes. The design of the threaded connection between the oil plug cap 6 and the oil pipe 7 makes it convenient for the user to inject lubricating oil into the oil pipe 7 in advance. The oil pipe 7 is connected to the lubrication cavity 8, and the lubrication cavity 8 is connected to the annular groove 9. The inertia and gravity when the slider 3 moves relative to the guide rail body 1 allow the lubricating oil to enter the annular groove 9 through the oil pipe 7 and the lubrication cavity 8, so that the ball 11 can rotate in the annular groove 9. When the slider 3 moves in contact with the lubricating oil, the ball 11 is lubricated when it rotates in the annular groove 9, which avoids the increase of friction resistance between the ball 11 and the annular groove 9 after multiple rotations, resulting in temperature rise and noise, and has a good stabilizing effect. Then, when the slider 3 fits the grooves 2 on both sides of the guide rail body 1, the metal baffle 1301 can be designed with a shape structure consistent with the shape structure of the groove 2, which is convenient for shielding and protecting the slider 3 from both sides of the slider 3 while ensuring the stable sliding of the slider 3, and the excess lubricating oil can be scraped off by the design of the scraper plate 1302, and the residual lubricating oil can be absorbed by the design of the sponge material oil absorption plate 1304, so as to keep the outer surface of the groove 2 clean and tidy, which is convenient for straight The linear guide rail is stably used, and then when the slider 3 moves along the position of the guide rail body 1, the design of the micro double-headed motor 17 can be used to drive the built-in column 18 and the blade 19 to rotate, so that the blade 19 can rotate quickly, and the dust or other particles attached to the inside of the groove 2 can be blown away by the rotation of the blade 19, so as to prevent dust from entering when the slider 3 moves along the outside of the groove 2, affecting the rotation of the ball 11 inside the slider 3, and maintaining the accuracy of the ball 11 during rotation. Through the design of the threaded connection between the built-in column 18 and the threaded column 2103, it is convenient to install the built-in frame 2105 connected to the threaded column 2103 inside the outer frame 2101, so that the built-in frame 2105 can be driven to rotate in the built-in groove 2102 when the built-in column 18 rotates. The cleaning brush 2104 on the outer surface of the built-in frame 2105 will rotate with the rotation of the built-in frame 2105, so that the dust or other attachments attached to the outer surface of the groove 2 can be cleaned by the rotating design of the cleaning brush 2104. While ensuring that the outer surface of the groove 2 is clean, the cleaning brush 2104 can also be self-cleaned by the rotation of the blade 19. Finally, the design of the micro double-headed motor 17 and the driving shaft can synchronously drive the driving roller 1602 to rotate while cleaning a group of grooves 2. The rotation of the driving roller 1602 and the design of the conveyor belt 1603 can drive the transmission bottom shaft 2001 and the built-in column 2 2002 to rotate, so that the built-in column 2 2002 and the blade 2 2003 can synchronously follow the rotation.In this way, the upper and lower grooves 2 can be cleaned synchronously, ensuring that there is no dust attached to the outside of the guide rail body 1 when in use, preventing impurities such as dust and smoke from affecting the processing accuracy of the device, preventing the aging of internal parts, and extending the service life of the device. In addition, the mounting column 14 is engaged with the mounting hole 12 for installation. Through the above installation, it is convenient to indirectly assemble the entire connecting vertical plate 15 and the slider 3, which is conducive to the assembly and use of the entire cleaning and dust removal structure and the slider 3.
