[0002] As an ideal precision transmission element for converting rotary motion into linear motion, or vice versa, ball screws play a vital role in modern mechanical transmission systems. They are mainly composed of key components such as screws, nuts, steel balls, pre-loaded plates, reversers, and dust collectors. Ball screws have many significant advantages. Their transmission efficiency is extremely high, usually reaching over 90%. Compared with traditional sliding screws, they can significantly reduce energy loss and improve energy utilization. At the same time, they have high-precision characteristics and can achieve micron-level positioning accuracy, meeting the needs of many applications with demanding precision. In addition, ball screws also have the advantage of high rigidity.

DETAILED DESCRIPTION
[0027] The following is a non-limiting detailed description of the technical solutions of the present invention in conjunction with preferred embodiments and the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
[0028] An embodiment of the present invention provides a ball screw shaft processing device, such as Figure 1As shown, the ball screw shaft processing equipment includes a bed 1, a movable support plate 2 is slidably connected to the bed 1, a grinding mechanism 3 is fixedly provided on the movable support plate 2, and filtering mechanisms 4 are provided on opposite sides of the grinding mechanism 3, and each filtering mechanism 4 is connected to a liquid spraying mechanism 5. The bed 1 serves as the basic supporting structure of the entire equipment, and the movable support plate 2 can perform precise linear movement on the bed 1. The movable support plate 2 drives the grinding mechanism 3 to grind the ball screw shaft according to a predetermined trajectory. The main function of the filtering mechanism 4 is to filter the cutting fluid and remove metal particles and impurities mixed in the cutting fluid. The liquid spraying mechanism 5 is responsible for evenly spraying the filtered cutting fluid into the grinding area to cool and lubricate the grinding parts and improve the grinding efficiency and quality.
[0029] like Figure 3 As shown, the grinding mechanism 3 includes a grinding frame 31 fixedly arranged above the movable support plate 2, a grinding wheel 32 is rotatably connected to the center of the upper section of the grinding frame 31, a power mechanism 33 is provided on one side of the upper section of the grinding frame 31, and a cooling element 9 is provided on one side of the grinding frame 31 adjacent to the surface where the power mechanism 33 is located, and a cutting fluid tank 34 is provided above the cooling element 9.
[0030] The grinding wheel 32 is a core component directly involved in the grinding process of the ball screw shaft. Its material selection and manufacturing need to focus on wear resistance and grinding efficiency to ensure that the cutting edge is sharp and wear is reduced under continuous high-speed cutting, while achieving efficient grinding; the power mechanism 33 is a key component that drives the grinding wheel 32 to rotate. Whether its performance is stable or not is directly related to the speed accuracy and operation smoothness of the grinding wheel 32, which in turn affects the grinding quality; the cutting fluid tank 34 is used to store cutting fluid. The cutting fluid has multiple functions such as cooling, lubrication, cleaning and rust prevention in grinding, and is an important medium to ensure processing accuracy and workpiece quality; and the cooling element 9 adopts a semiconductor refrigeration device, which can accurately and efficiently cool the cutting fluid, ensuring that the cutting fluid flowing out of the cutting fluid tank 34 is always in a low temperature state, thereby absorbing heat more quickly during the grinding process, greatly enhancing the cooling effect, and reducing the risk of wear of the grinding wheel 32 and thermal deformation of the workpiece.
[0031] like Figure 4As shown, the filtering mechanism 4 includes two rotating inner cylinders 41 respectively arranged on opposite sides of the cutting fluid box 34, each of the rotating inner cylinders 41 is connected to the interior of the cutting fluid box 34, and each of the rotating inner cylinders 41 is rotated with the cutting fluid box 34, and each of the rotating inner cylinders 41 is provided with a plurality of slag holes 411, and a slag collecting outer cylinder 42 is provided on the outside of each rotating inner cylinder 41, and the slag collecting outer cylinder 42 on the same side is rotated with the rotating inner cylinder 41 and is located at the slag hole 41 1, each of the slag collecting outer cylinders 42 is connected to a connecting shell 43 at one end away from the cutting fluid tank 34, and a rotating ring 431 is provided inside each of the connecting shells 43. A connecting ball 432 is rotatably connected to each of the rotating rings 431, and a hanging plate 433 is connected below each of the connecting balls 432. A plurality of blades 434 and a plurality of magnetic rods 435 are provided below each of the hanging plates 433. A collecting box 436 is provided on one side of the rotating ring 431 below the magnetic rods 435.
[0032] During the operation of the filtering mechanism 4, when the rotating inner cylinder 41 starts to rotate, the impurities mixed in the cutting fluid will be subjected to an outward throwing force due to the action of centrifugal force. At this time, the impurities in the cutting fluid will be thrown out into the slag collecting outer cylinder 42 through the several slag holes 411 opened on the rotating inner cylinder 41. As the filtering work continues, a certain amount of impurities will gradually accumulate in the slag collecting outer cylinder 42. After using it for a period of time, the operator can remove the slag collecting outer cylinder 42 from the rotating inner cylinder 41, clean the impurities accumulated inside it, and reinstall it after cleaning. The reinstalled slag collecting outer cylinder 42 is fixed relative to the cutting fluid box 34 to ensure the stable operation of the entire filtering mechanism 4.
[0033] When the cutting fluid flows from the slag collecting outer cylinder 42 into the connecting shell 43, the flow of the cutting fluid will generate an impact force on the blades 434. Under the action of the impact force, the blades 434 will rotate and drive the magnetic rod 435 to rotate together through the hanging plate 433. The magnetic rod 435 is magnetic and can absorb ferromagnetic impurities in the cutting fluid during the rotation process. With the continuous flow of cutting fluid, the continuous rotation of the magnetic rod 435 and the influence of gravity, the impurities adsorbed on the magnetic rod 435 will gradually move along the surface of the magnetic rod 435, and eventually fall into the collection box 436 provided on the rotating ring 431 on the side below the magnetic rod 435, thereby realizing the effective collection of ferromagnetic impurities.
[0034] A filter screen 44 is provided at one end of the rotating inner cylinder 41 close to the cutting fluid tank 34 , and a fine filter paper 45 is provided at one end of the communicating shell 43 away from the cutting fluid tank 34 .
[0035] When the cutting fluid first enters the filtering mechanism 4, the filter screen 44 disposed within the rotating inner cylinder 41 near the end of the cutting fluid tank 34 performs a coarse filtration on the cutting fluid, initially intercepting larger impurities in the cutting fluid and preventing them from entering the subsequent filtration stages, which could affect the filtration effect and the normal operation of the equipment. After coarse filtration, the cutting fluid continues to flow, and as it passes through the fine filter paper 45 disposed within the connecting shell 43, away from the end of the cutting fluid tank 34, it performs a fine filtration on the cutting fluid, further removing tiny impurity particles from the cutting fluid, ultimately allowing the finely filtered cutting fluid to flow out for use in subsequent grinding operations.
[0036] In certain preferred embodiments, Figure 1 As shown, the bed 1 is also fixedly provided with a workpiece headstock 6 and a workpiece tailstock 7. The workpiece headstock 6 and the workpiece tailstock 7 are opposite to each other, and a ball screw 8 to be processed is clamped and connected between the workpiece headstock 6 and the workpiece tailstock 7. The ball screw 8 to be processed is parallel to the sliding path of the movable support plate 2. Specifically, the two ends of the ball screw 8 to be processed are precisely clamped and connected by the workpiece headstock 6 and the workpiece tailstock 7, respectively, to ensure that the ball screw 8 to be processed remains stable during the processing process.
[0037] In certain preferred embodiments, Figures 3 to 5 As shown, the liquid spraying mechanism 5 includes a connecting tube 51, one end of which communicates with the interior of the connecting housing 43. The other end of each connecting tube 51 is connected to a spiral elastic tube 52. The spiral elastic tube 52 is an elastic spiral structure with a liquid flow channel inside. A plurality of spray heads 53 are evenly arranged on the spiral elastic tube 52. The ends of the spiral elastic tube 52 are respectively fixedly connected to a first bracket 54 and a second bracket 55. The first bracket 54 is fixedly mounted on the grinding frame 31. A telescopic rod 56 is connected between the first bracket 54 and the second bracket 55.
[0038] During the grinding process, cutting fluid first flows out of the connecting shell 43 and is smoothly input into the interior of the spiral elastic tube 52 via the connecting tube 51. Because the spiral elastic tube 52 is provided with a dedicated liquid flow channel, the cutting fluid can flow stably along this flow channel and is ultimately evenly sprayed out through the multiple nozzles 53 evenly distributed on the spiral elastic tube 52, providing the necessary cooling and lubrication for the grinding area.
[0039] At the same time, the telescopic rod 56 can be flexibly adjusted according to the actual pitch specifications of the ball screw 8 being machined. When the cutting fluid spray range needs to be changed to match different pitches, the telescopic rod 56 is extended and retracted. When the telescopic rod 56 retracts, it pulls the second bracket 55 toward the first bracket 54. Due to the elasticity of the spiral elastic tube 52, its spiral pitch gradually decreases under the pull of the second bracket 55. At this time, the cutting fluid sprayed from the nozzle 53 is more concentratedly covered on a localized area of the ball screw 8 being machined, making it suitable for machining ball screws with smaller pitches and ensuring sufficient cooling and lubrication of the smaller pitch screw grooves. Conversely, when the telescopic rod 56 is extended, it pushes the second bracket 55 away from the first bracket 54, increasing the spiral pitch of the spiral elastic tube 52. This expands the cutting fluid spray range, better covering the surface of the ball screw 8 with larger pitches being machined and avoiding blind spots.
[0040] By dynamically adjusting the spiral pitch of the spiral elastic tube 52, the spray range of the cutting fluid can be accurately matched with the pitch of the ball screw 8 to be processed, thereby ensuring that the cutting fluid is evenly distributed in the grinding area, effectively reducing the grinding temperature, reducing tool wear, improving the quality and accuracy of the processed surface, and ultimately achieving better processing results.
[0041] In certain preferred embodiments, Figure 6 As shown, a central shaft 331 is provided in the center of the grinding wheel 32. One end of the central shaft 331 passes through the grinding frame 31 and is connected to one end of a coupling 332. The other end of the coupling 332 is connected to a grinding motor 333. The grinding motor 333 is fixedly disposed inside a motor housing 334, which is fixedly disposed on the grinding frame 31. The grinding motor 333 is used to provide power to the grinding wheel 32.
[0042] In certain preferred embodiments, Figure 3As shown, transmission wheels 412 are provided on both sides of the cutting fluid tank 34, where the filter mechanism 4 is located. These transmission wheels 412 are connected to a power source, and a conveyor belt 413 is connected to both the transmission wheel 412 and the rotating inner cylinder 41. The power source drives the transmission wheel 412 to rotate. Because the transmission wheel 412 and the rotating inner cylinder 41 are tightly connected via the conveyor belt 413, an efficient power transmission system is formed. The conveyor belt 413 is made of high-strength, wear-resistant material, capable of withstanding significant tension and friction, ensuring stable and reliable power transmission. As the transmission wheel 412 rotates, the friction between its surface and the conveyor belt 413 drives the conveyor belt 413 to move synchronously. The conveyor belt 413 is, in turn, connected to the rotating inner cylinder 41, driving the rotating inner cylinder 41 in turn.
[0043] In certain preferred embodiments, Figure 1 As shown, a sliding groove 11 is provided on the bed 1 , and the movable support plate 2 is slidably matched with the sliding groove 11 .
[0044] In certain preferred embodiments, Figure 2 As shown, a water pump is further provided in the cutting fluid tank 34. A support plate 35 is fixedly provided on the cutting fluid tank 34 below the cooling element 9. A roller 351 is rotatably connected to the side of the support plate 35 away from the cutting fluid tank 34. The support plate 35 is used to place and support the cooling element 9 and the cutting fluid tank 34. The roller 351 facilitates the support plate 35 to drive the cooling element 9 and the cutting fluid tank 34 to slide along the movable support plate 2.
[0045] In certain preferred embodiments, the telescopic rod 56 is driven to ensure that the pitch of the spiral elastic tube 52 is 1.5-2 times the desired pitch of the spirals on the ball screw 8 to be machined. This ensures that the cutting fluid covers the entire machining area of the ball screw 8 to be machined, avoiding blind spots and thus ensuring effective cooling and lubrication during machining. The spray nozzles 53 are spaced 1 / 2 to 2 / 3 the desired pitch of the spirals on the ball screw 8 to be machined. This ensures that the cutting fluid is sprayed at an appropriate density on the surface of the ball screw 8 to be machined, while preventing waste or interference of the cutting fluid due to overly dense spray nozzles 53.
[0046] In certain preferred embodiments, the mass of the collection box 436 is greater than the combined mass of the connecting ball 432, the hanging plate 433, the blades 434, and the magnetic rod 435, ensuring that the collection box 436 is always located at the bottom of the rotating ring 431. Based on the principles of physics and mechanics, as the rotating ring 431 rotates, the collection box 436, with its greater mass, is subject to a greater gravity effect, due to the constant presence and downward direction of gravity. When the angle of the connecting shell 43 shifts, the greater the mass, the more pronounced the gravity effect under the same gravitational acceleration, according to the laws of motion of objects in a gravitational field. Therefore, the collection box 436, leveraging its greater gravity, remains at the bottom of the rotating ring 431 during rotation, even if the angle of the connecting shell 43 changes, thereby stably performing its collection function.
[0047] In the above embodiment, the bed 1, the movable support plate 2, the grinding mechanism 3, the filtering mechanism 4, and the liquid spraying mechanism 5 work together to achieve efficient and precise grinding of the ball screw shaft. The grinding wheel 32 in the grinding mechanism 3 rotates at high speed under the drive of the power mechanism 33 to grind the ball screw 8 to be machined, which is clamped between the workpiece headstock 6 and the workpiece tailstock 7.
[0048] The core function of the filter mechanism 4 is to efficiently filter the cutting fluid. When the rotating inner cylinder 41 rotates under the power source, the cutting fluid, under the action of centrifugal force, is swept through the slag holes 411 in the rotating inner cylinder 41 and into the slag collection outer cylinder 42, achieving preliminary solid-liquid separation. Accumulated impurities in the slag collection outer cylinder 42 can be regularly cleaned. As the cutting fluid flows from the slag collection outer cylinder 42 into the connecting shell 43, the impact force causes the blades 434 to rotate the magnetic rod 435, which absorbs ferromagnetic impurities in the cutting fluid and, under the action of gravity, directs the absorbed impurities into the collection box 436. The filter screen 44, located at the end of the rotating inner cylinder 41 near the cutting fluid tank 34, performs coarse filtration of the cutting fluid, intercepting larger impurity particles. The fine filter paper 45, located at the distal end of the connecting shell 43, performs fine filtration of the cutting fluid, removing fine impurity particles. Finally, the clean cutting fluid, after multiple filtration steps, exits the filter mechanism 4, ensuring continued grinding processing.
[0049] The spray mechanism 5 delivers filtered cutting fluid to the spiral elastic tube 52 via the connecting pipe 51. The nozzles 53, evenly distributed on the spiral elastic tube 52, spray the cutting fluid onto the grinding area. The telescopic rod 56 adjusts the pitch of the spiral elastic tube 52 according to the pitch specifications of the ball screw 8 being machined, ensuring that the pitch is 1.5-2 times the desired pitch of the ball screw 8. This ensures that the cutting fluid covers the entire machining area and avoids blind spots. Furthermore, the nozzles 53 are spaced 1 / 2 to 2 / 3 the desired pitch of the ball screw 8 being machined, ensuring a denser spray of the cutting fluid and preventing waste and interference.
