Description

Technical Field

[0002] Anti-fouling ball screw is a mechanical component used in transmission systems. In modern industrial production and mechanical manufacturing, precision and reliability are crucial. As a precision transmission component that converts rotational motion into linear motion, ball screw is widely used in various mechanical equipment.

[0003] In a long-term, complex working environment, contaminants will gradually penetrate and accumulate. These contaminants cannot be actively removed, affecting the normal operation of the device, resulting in the need for more frequent comprehensive inspections and maintenance work, including disassembling the device, cleaning the interior, and replacing damaged parts. This consumes a lot of manpower, material resources, and time. During equipment operation, surrounding objects may collide with the ball screw, causing scratches, dents, or even bending on the screw surface. When exposed to the external environment, moisture, chemicals, etc., may directly erode the surface of the ball screw, causing it to rust and corrode, reducing its strength and durability. Dust, metal debris, and other impurities in the air are more likely to enter the interior of the ball screw, increasing friction between the ball and the screw, affecting its operating accuracy and smoothness. When the protective device is disassembled for cleaning, without a quick-release fixing mechanism, the protective device may become difficult to quickly remove and reinstall, affecting the efficiency of regular maintenance and inspections. These tasks may require more time and labor to complete, thereby increasing operating and maintenance costs. Summary of the Invention

[0017] The present invention also provides an anti-fouling ball screw assembly and a method for using the same, the specific method comprising the following steps:

[0018] Step 1: The gas in the gas pipe enters the transfer pipe and finally reaches the spray pipe. The nozzle on the spray pipe sprays the gas in a specific direction and pressure. Since the nozzle is set in the fixed groove inside the curved plate, the sprayed gas can effectively clean and purge the area inside and around the curved plate.

[0019] Step 2: When the screw rotates, it drives the internal device of the second shell to slide on the outside of the screw, and the brush inside the fixed cylinder on the left end of the second shell contacts the outside of the screw, etc., and further brushes off the dirt on the screw by moving. The cleaned pollutants are discharged into the interior of the arc plate through the first drain hole at the bottom of the fixed cylinder and the second drain hole at the bottom of the lower semicircular cover.

[0020] Step 3: The first guide grooves inside the two storage boxes on the left side of the mounting block and the right side of the second baffle provide moving tracks for the support rod. When protection is required, the isolation cover fixed on the outer wall of the support rod moves along the first guide groove and slides in connection with the top hole groove of the fixed block at the bottom, thereby forming protection for the top of the bottom plate and the outside of the curved plate, preventing external impurities and pollutants from directly contacting and entering the interior of the curved plate.

[0021] Step 4: The support rod inside the first shell moves backward under the push of the card block, and the first spring connected to it is also compressed. When the card block completely enters the first placement groove, the support rod will rebound, so that the other side of the support rod is inserted into the interior of the card block, thereby firmly fixing the card block in the first placement groove, realizing a stable connection between the storage box and the bottom plate.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention solves the problem of needing to carry out more frequent comprehensive inspections and maintenance work, including disassembling the device, cleaning the interior, replacing damaged parts, etc., which consumes a lot of manpower, material resources and time, by providing a cleaning mechanism. The connecting pipe is connected to an external air pump, etc. to transport gas to the interior of the connecting pipe. After the connecting pipe receives the external gas, the gas enters the delivery pipe through the connecting pipe and is then evenly distributed to the gas pipes on the front and rear sides. Then, the gas in the gas pipe enters the transfer pipe respectively and finally reaches the spray pipe. The nozzle on the spray pipe sprays gas in a specific direction and pressure. Since the nozzle is set in a fixed groove inside the curved plate, the sprayed medium can effectively clean and purge the area inside and around the curved plate. When the screw drives the second shell and the internal device to slide, the lower semi-circular cover at the bottom of the second shell drives the scraper and the guide plate to slide in the device inside the curved plate. The scraper can scrape off stubborn stains and impurities attached to the inside of the curved plate, thereby effectively improving the operating accuracy and smoothness, as well as the overall performance and efficiency of the device, and can achieve the goal of cleaning the interior during operation.

[0024] 2. The protective mechanism set up can solve the problems of rust and corrosion, reduced strength and durability, and impurities such as dust and metal debris in the air more easily entering the interior of the ball screw, increasing the friction between the ball and the screw, and affecting its running accuracy and smoothness. The first guide groove inside the two storage boxes on the left side of the mounting block and the right side of the second baffle provides a moving track for the support rod. When protection is needed, the isolation cover fixed to the outer wall of the support rod moves along the first guide groove and is slidably connected to the top hole groove of the fixed block at the bottom, thereby forming protection for the top of the bottom plate and the outside of the curved plate, preventing external impurities and pollutants from directly contacting and entering the interior of the curved plate, thereby effectively reducing damage, repair and replacement of the ball screw, thereby improving production efficiency and preventing economic losses.

[0025] 3. The quick-release fixing mechanism can solve the problem of affecting the efficiency of regular maintenance and inspection, requiring more time and labor to complete these tasks, thereby increasing operating and maintenance costs. When the storage box is installed on both sides of the base plate, the card block at the bottom of the storage box is aligned with the first placement slot inside the first shell. During the insertion of the card block, the card block will first contact the first baffle and press the first baffle downward. At this time, the second spring connected to the first baffle is compressed. At the same time, the support rod inside the first shell moves backward under the push of the card block, and the first spring connected to it is also compressed. When the card block is fully inserted into the first placement slot, the support rod will rebound due to the first spring, causing the other side of the support rod to be inserted into the interior of the card block, thereby firmly fixing the card block in the first placement slot, achieving a stable connection between the storage box and the base plate, preventing external impurities from entering the interior, thereby effectively improving the use efficiency, safety and maintenance cost of the protective mechanism, and achieving a quick disassembly and installation effect to reduce damage to the device.

[0026] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] Step 2: When the screw 11 rotates, it drives the internal device of the second housing 13 to slide on the outside of the screw 11. The brush 211 inside the fixed cylinder 210 on the left end of the second housing 13 contacts the outside of the screw 11, and further brushes away the dirt on the screw 11 by moving. The cleaned pollutants are discharged into the interior of the curved plate 9 through the first drain hole 212 at the bottom of the fixed cylinder 210 and the second drain hole 309 at the bottom of the lower semi-circular cover 308.

[0057] Step 3: The first guide grooves 302 inside the two storage boxes 301 on the left side of the mounting block 5 and the right side of the second baffle 21 provide a moving track for the support rod 303. When protection is required, the isolation cover 304 fixed to the outer wall of the support rod 303 moves along the first guide groove 302 and is slidably connected to the top hole groove of the fixed block 10 at the bottom, thereby forming protection for the top of the bottom plate 1 and the outer side of the curved plate 9, preventing external impurities and contaminants from directly contacting and entering the interior of the curved plate 9;

[0058] Step 4: The support rod 402 inside the first shell 401 moves backward under the push of the block 407, and the first spring 403 connected to it is also compressed. When the block 407 completely enters the first placement groove 404, the support rod 402 will rebound through 403, so that the other side of the support rod 402 is inserted into the interior of the block 407, thereby firmly fixing the block 407 in the first placement groove 404, realizing a stable connection between the storage box 301 and the bottom plate 1.

[0059] It should be noted that the present invention is a fouling-proof ball screw assembly. First, the connecting tube 201 is connected to an external air pump, etc. to transport the gas to the interior of 201. After the connecting tube 201 receives the external gas, the gas will enter the delivery pipe 202 through the connecting tube 201, and then be evenly distributed to the gas pipes 203 on the front and rear sides. Then, the gas in the gas pipe 203 enters the transfer pipe 204 respectively, and finally reaches the spray pipe 205. The nozzle 206 on the spray pipe 205 sprays gas in a specific direction and pressure. Since the nozzle 206 is arranged in the fixed groove 207 inside the curved plate 9, the sprayed medium can effectively clean and purge the area inside and around the curved plate 9. When the screw 11 rotates, it will drive the internal device of the second shell 13 to slide on the outside of the screw 11. The brush 211 inside the fixed cylinder 210 on the left end of the second shell 13 contacts the outside of the screw 11, and further brushes off the dirt on the screw 11 by moving. The cleaned pollutants are discharged into the interior of the curved plate 9 through the first drain hole 212 at the bottom of the fixed cylinder 210 and the bottom 309 of 308. When the screw 11 drives the interior of the second shell 13 and the protective mechanism 3 to slide, the lower semi-circular cover 308 drives the scraper 208 and the guide plate 209 to slide inside the curved plate 9. The scraper 208 can scrape off stubborn stains and impurities attached to the inside of the curved plate 9, and the guide plate 209 can guide the impurities and the wind discharged from the nozzle 206, so that the wind discharged from the front and rear sides is guided and flows on the scraper 208 and the guide plate 209 to achieve rotation, to prevent impurities from flowing into the rear during cleaning, and to clean the surface of the scraper 208 and the guide plate 209.

[0060] The pollutants generated during the cleaning process are discharged through the second drain hole 309 at the bottom of the lower semicircular cover 308. Since the second drain hole 309 is arranged corresponding to the first drain hole 212 at the bottom of the fixed cylinder 210, the discharged pollutants can flow out smoothly and will not accumulate inside.

[0061] The cleaned pollutants will be pushed into the left side wall of the second baffle 21 , and the support block 20 will be taken out from the second baffle 21 to discharge the impurities out of the bottom plate 1 .

[0062] The first guide groove 302 inside the two storage boxes 301 on the left side of the mounting block 5 and the right side of the second baffle 21 provides a moving track for the support rod 303. When protection is needed, the isolation cover 304 fixed on the outer wall of the support rod 303 moves along the first guide groove 302 and is slidably connected to the top hole groove of the fixed block 10 at the bottom, thereby forming protection for the top of the bottom plate 1 and the outside of the curved plate 9, preventing external impurities and pollutants from directly contacting and entering the interior of the curved plate 9. When the nut 12 and the steel ball 15 inside the second shell 13 are driven to rotate and slide by 11, the outside will be set at the top of the second shell 13 through the upper semicircular cover 305, and the sliders 307 at the bottom of the first fixed plate 306 on the front and rear sides of the bottom of the upper semicircular cover 305 can slide in the second guide groove 311 inside the second fixed plate 310 on the bottom of the second shell 13. In this way, the upper semicircular cover 305 and the lower semicircular cover 308 can move relative to each other, and the slider 307 sliding inside the second guide groove 311 can be limited by the limit block 312 to prevent excessive sliding that causes the second shell 13 to be unable to be fixed on the outside, and to achieve wrap-around protection for the second shell 13.

[0063] When the storage box 301 is installed on both sides of the bottom plate 1, the block 407 at the bottom of the storage box 301 is aligned with the first placement groove 404 inside the first shell 401. During the insertion of the block 407, the block 407 will first contact the first baffle 406 and press the first baffle 406 downward. At this time, the second spring 405 connected to the first baffle 406 is compressed. At the same time, the support rod 402 inside the first shell 401 moves backward under the push of the block 407, and the first spring 403 connected thereto is also compressed. When the block 407 completely enters the first placement groove 404, the support rod 402 will rebound through the first spring 403, so that the other side of the support rod 402 is inserted into the interior of the block 407, thereby firmly fixing the block 407 in the first placement groove 404, realizing a stable connection between the storage box 301 and the bottom plate 1. When it needs to be disassembled, the support rod 402 is pressed to slide in the sliding of the first shell 401 to squeeze the first spring 403 and remove the block 407 from the first placement groove 404. When the support rod 402 is released, it will rebound. At the same time, the second spring 405 will drive the first baffle 406 to rebound, thereby closing the inlet and outlet of the first placement groove 404 to prevent external impurities from entering the interior.
