Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission equipment technology, and in particular to a ball screw with dustproof function. Background Technology

[0002] A ball screw is a high-precision, high-efficiency mechanical transmission device that converts rotary motion into linear motion. It replaces traditional sliding friction with rolling friction of balls between the screw and nut, significantly reducing frictional resistance and improving transmission efficiency and positioning accuracy.

[0003] In modern industrial automation equipment, ball screws are widely used as the core component for achieving high-precision linear motion in CNC machine tools, semiconductor manufacturing equipment, medical testing instruments and other fields. The stability and accuracy of their operation directly affect the overall performance of the equipment. However, in complex and ever-changing working environments, dust, metal shavings and other impurities can easily penetrate the mating area between the screw and the nut, leading to a decrease in transmission efficiency, loss of accuracy, and even mechanical failure. The existing integrated protective cover structure is tightly and complexly assembled with the ball screw and nut. When the internal dustproof components wear or become clogged due to long-term use, the disassembly process often requires the use of special tools, which consumes a lot of time and labor costs. Even if some dustproof devices support disassembly, the replacement of their dustproof components requires the complete removal of the entire protective cover from the equipment. This not only affects the normal operation of the equipment, but may also cause other components to loosen or be damaged due to frequent disassembly and assembly. In addition, the non-removable or difficult-to-disassemble design makes it difficult to clean and maintain the dustproof components regularly, and the dust accumulation problem cannot be effectively solved, which further shortens the service life of the ball screw.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1, according to Figures 1-5 As shown, a ball screw with dustproof function includes a screw body 1, a nut housing 2 is provided on the outer wall of the screw body 1, a dustproof component 3 is provided on the outer wall of the nut housing 2, and a collection component 4 is installed on the outer wall of the dustproof component 3. The dustproof component 3 includes a support frame 301 symmetrically fixed to the outer wall of the nut housing 2. The outer surface of the nut housing 2 is provided with a first annular mounting bracket 305 and a second annular mounting bracket 3051. The top of both the first and second annular mounting brackets 305 and 3051 has a slot 306. The interior of the two slots 306 engages with the outer wall of the locking block 304. The outer wall of the nut housing 2 is symmetrically provided with sliding grooves 307. The interior of the sliding grooves 307 is slidably connected to the first and second annular mounting blocks. The outer wall of the first annular mounting block is symmetrically provided with insertion holes 308, and the outer wall of the second annular mounting block is symmetrically provided with insertion posts 3081. The interior of the insertion holes 308 engages with the outer wall of the insertion posts 3081. The inner walls of both the first and second annular mounting blocks are provided with a set of mounting grooves 309 at equal intervals. The inner walls of both sets of mounting grooves 309 are engaged with a first dust scraper 310 and a second dust scraper 31. 1. A set of mounting blocks 312 are fixedly connected at equal intervals to the outer walls of the first dust scraper 310 and the second dust scraper 311. The outer walls of the two sets of mounting blocks 312 are engaged with the inner walls of the mounting grooves 309. The outer wall of the first dust scraper 310 is symmetrically provided with square grooves 313. The outer wall of the second dust scraper 311 is symmetrically fixedly connected with square blocks 314. The inner walls of the square grooves 313 are engaged with the outer walls of the square blocks 314. The top of the support frame 301 is connected to an electric push rod 302 by screws. The output end of the electric push rod 302 penetrates the support frame 301 and is fixedly connected to a connecting block 303. The bottom of the connecting block 303 is symmetrically fixedly connected with a locking block 304. The outer walls of the first annular mounting frame 305 and the second annular mounting frame 3051 are both fixedly connected with sliders. The outer walls of the sliders are slidably connected to the inside of the sliding groove 307. The locking block 304 and the locking groove 306 are square structures, and the locking block 304 and the locking groove 306 are compatible.

[0018] The overall effect of Embodiment 1 is as follows: the first dust scraper 310 and the second dust scraper 311 on the inner wall of the first annular mounting block and the second annular mounting block are tightly attached to the outer wall of the lead screw body 1 through the engagement of the mounting groove 309 and the mounting block 312. When the lead screw body 1 is working, the first dust scraper 310 and the second dust scraper 311 can promptly scrape away the dust and impurities attached to the surface of the lead screw, preventing them from entering the mating part between the lead screw body 1 and the nut housing 2, effectively avoiding problems such as lead screw wear and jamming caused by dust, extending the service life of the lead screw, and ensuring the stability of equipment operation. The first annular mounting bracket 305, the second annular mounting bracket 3051 and the nut housing 2 are connected by a slider and a sliding groove 307. The sliding connection and the engagement of the locking block 304 and the locking slot 306 enable the rapid installation and disassembly of the dustproof component 3. Simultaneously, the first and second annular mounting blocks are engaged via the insertion hole 308 and the insertion post 3081, and the first and second dust scraper blades 310 and 311 are engaged via the square slot 313 and the square block 314, facilitating the replacement of worn dust scraper blades, reducing maintenance costs, and improving maintenance efficiency. The electric push rod 302 at the top of the support frame 301, with its output end connected to the connecting block 303 and the locking block 304, allows for adjustment of the engagement state of the locking block 304 and the locking slot 306 by extending and retracting the electric push rod 302, thereby adjusting the position and working state of the dustproof component 3. When the equipment requires high-precision operation, the electric push rod 302 can make the dust scraper blades fit more tightly against the lead screw, enhancing the dustproof effect. When the equipment is idle or needs to be moved quickly, the position of the dustproof component 3 can be adjusted appropriately to reduce frictional resistance.

[0019] Example 2, according to Figure 5 As shown, the collecting component 4 includes a set of cylindrical grooves 401 symmetrically opened in the first annular mounting frame 305 and the second annular mounting frame 3051. Both the first annular mounting frame 305 and the second annular mounting frame 3051 are provided with annular frames 402 on their outer sides. A set of protrusions 403 are fixedly connected at equal intervals to the outer sides of the two annular frames 402. The outer walls of the two sets of protrusions 403 are engaged with the interior of the cylindrical grooves 401. Magnetic blocks 404 are fixedly connected to the outer walls of the two sets of protrusions 403. A collecting groove 405 is opened inside the two annular frames 402 for collecting debris. The first annular mounting frame 305 and the second annular mounting frame 3051 are stainless steel metal parts. The outer walls of the two sets of magnetic blocks 404 are magnetically connected to the interior of the cylindrical grooves 401.

[0020] The overall effect of Embodiment 2 is as follows: The collection groove 405 inside the annular frame 402 provides a dedicated storage space for dust and debris scraped off by the dust scraper. As the lead screw body 1 operates, the scraped-off impurities can fall directly into the collection groove 405, effectively preventing debris from scattering around the equipment. This not only maintains the cleanliness of the working environment but also prevents debris from re-adhering to the lead screw surface, enhancing the dustproof effect and ensuring the stable operation of the lead screw body 1. The annular frame 402 is engaged with the cylindrical grooves 401 on the first annular mounting bracket 305 and the second annular mounting bracket 3051 via the protrusion 403. Combined with the magnetic connection between the magnetic block 404 and the stainless steel mounting bracket, this double fixing method ensures that the annular frame 402 is securely installed and will not easily loosen or fall off during the operation of the lead screw body 1. When it is necessary to clean the collection groove 405... When collecting debris, the annular frame 402 can be easily disassembled for quick cleaning, improving equipment maintenance efficiency. The structural design of the annular frame 402, protrusion 403, and magnetic block 404 allows it to fit tightly against the outside of the first annular mounting bracket 305 and the second annular mounting bracket 3051, perfectly matching the overall structure of the dustproof component 3. This compatibility ensures that the collecting component 4 efficiently completes the debris collection task without affecting the normal operation of the dustproof component 3, further enhancing the overall performance of the ball screw with dustproof function.

[0021] The working principle of the entire device is as follows: The first annular mounting bracket 305 and the second annular mounting bracket 3051 are slidably connected to the slide groove 307 via a slider. At this time, the first dust scraper 310 and the second dust scraper 311 installed in the mounting groove 309 are tightly attached to the outer wall of the lead screw, and the pressure generated by their elastic deformation scrapes off the dust and impurities attached to the outside of the lead screw body 1. The dust scrapers form an annular sealing structure through the snap-fit ​​of the square groove 313 and the square block 314, ensuring all-round dust removal without dead corners. The electric push rod 302 on the support frame 301 The locking block 304 disengages from the slot 306, thereby separating the first annular mounting bracket 305 from the second annular mounting bracket 3051. This facilitates the later disassembly and replacement of the first dust scraper 310 and the second dust scraper 311. When the first annular mounting bracket 305 and the second annular mounting bracket 3051 are closed, the electric push rod 302 drives the locking block 304 to engage with the slot 306, thus fixing the entire dustproof assembly 3. When the device is in use, the dust and debris scraped off by the dust scraper fall directly into the collection groove 405 of the annular frame 402 under the action of gravity. Because the annular frame 402 is fixed to the outside of the dustproof assembly 3 by the engagement of the protrusion 403 with the cylindrical groove 401 and the magnetic attraction of the magnetic block 404 with the stainless steel mounting bracket, the collection groove 405 always moves with the dust scraper, ensuring that debris is collected as it is scraped, avoiding secondary dust or debris accumulation. When the internal debris accumulates to a certain amount, the annular frame 402 can be disassembled for cleaning simply by manually overcoming the magnetic attraction and pulling out the protrusion 403. The first annular mounting bracket 305 and the second annular mounting bracket 3051, made of stainless steel, not only provide a carrier for magnetic connection, but also have corrosion resistance properties to ensure the stability of the connection structure during long-term use.

[0022] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
