Description

Technical Field

[0001] This invention relates to the field of spherical grinding technology, specifically to a ball grinding device with a rotary ball guide rail. Background Technology

[0002] In the actual mechanical manufacturing of balls for rotary ball guides, after the initial rough machining, the balls need to be ground to improve the smoothness and precision of the ball surface. Rotary grinding machines are typically used for ball surface grinding, primarily employing grinding fluid for fine grinding. However, current rotary ball guide grinding devices suffer from poor fluid circulation during ball surface grinding, easily leading to fluid accumulation and reduced grinding precision. Furthermore, in batch grinding, it's difficult to ensure even distribution of the balls under the rotary grinding machine's rotating disc. If the balls are not evenly distributed, it affects the consistency of the disc's clamping force on each ball, resulting in significant deviations in grinding speed and precision, thus impacting grinding quality. Additionally, traditional rotary grinding primarily uses raceway grinding, where the balls typically roll in the same direction during rotation, resulting in poor overall grinding coverage and making it difficult to automatically control multi-directional ball rotation to improve grinding coverage.

[0003] Therefore, we propose a ball grinding device for a rotary ball guide. Summary of the Invention

[0016] By using a ring of ball bearings for grinding, the spacing between the balls in the ring is ensured to be the same.

The drive sleeve 3011 is fixedly installed at the bottom of the rotating disk 301, and the outer side of the drive sleeve 3011 has a hexagonal structure; the drive sleeve 3011 is slidably sleeved inside the drive cylinder 2011; the drive sleeve 3011 is slidably sleeved on the outside of the threaded tube 2012; the extrusion screw 202 passes through the rotating disk 301 and the drive sleeve 3011; the other end of the pressure spring 204 is fixedly connected to the rotating disk 301; the bottom of the drive sleeve 3011 is fixed.

At the same time, this structure uses the friction drive of the rubber strip 302 to drive the ball to rotate, which can realize active grinding of the ball, avoiding the problem of low grinding efficiency caused by the traditional grinding of balls in the raceway, where the balls mainly roll and grind. In addition, this structure, by using the liquid guide groove 4012 and the leakage hole 4013, can keep the grinding fluid sufficient. The grinding fluid is discharged in a way that prevents excessive grinding chips from accumulating inside the grinding groove 4011, which would affect the subsequent grinding quality. This also improves the quality of the grinding fluid flow and avoids the problem of excessive grinding chip accumulation that often occurs with traditional grinding methods where balls are ground within a raceway. A grinding fluid pump connected to the inlet pipe 104 supplies grinding fluid in real time, which is then discharged into the collection tank 3012 and out through a through-hole. The grinding fluid then flows into the guide tank 4012 to fully participate in ball grinding. Simultaneously, the grinding fluid and any mixed grinding chips are discharged in real time through the leakage hole 4013. The discharge groove 1023, connected to the leakage hole 4013, ensures that the grinding fluid flows into the guide groove 1021 and then out through the discharge hole 1022.

[0023] The ball bearing grinding component 4 further includes: a return spring 402, one end of which is fixedly connected to the bottom of the grinding mounting post 401; the other end of the return spring 402 abuts against the top of the grinding frame 101; the return spring 402 is located outside the position switch 1011; the return spring 402 is located inside the grinding fixing plate 102; the cleaning scraper component 5 includes: a scraping slide plate 501 and a cleaning spring 502, the top of the scraping slide plate 501 has an arc-shaped structure; the scraping slide plate 501 is slidably inserted into the grinding fixing plate 102; the top of the scraping slide plate 501 elastically fits the bottom of the rubber strip 302; the cleaning spring 502 is sleeved inside the grinding fixing plate 102; one end of the cleaning spring 502 is fixedly connected inside the grinding fixing plate 102, and the other end of the cleaning spring 502 is fixedly connected to the bottom of the scraping slide plate 501; the cleaning scraper component 5 can be used to clean the rubber strip When the 302 rotating friction ball bearings are in operation, the bottom of the automatic cleaning and scraping rubber strip 302 is cleaned to prevent excessive iron filings and impurities from adhering to the bottom of the rubber strip 302. By setting a ring of ball bearing grinding parts 4, it is ensured that the spacing of the balls in the ring is the same. After the rotating disk 301 presses down and adheres to the ball bearings, the pressure on the balls in the ring is more consistent, resulting in better grinding consistency. With the one-ring completion switch 1011, it can automatically detect whether balls are placed on the ring of ball bearing grinding parts 4. If balls are forgotten to be placed, the drive motor 201 can be automatically controlled to cut off the power, preventing normal grinding drive work. This can prevent balls from being forgotten to be placed on the ball bearing grinding parts 4 in some areas, which would result in a lack of ball support when the rotating disk 301 presses down on the balls. If the missing area is large, the rotating disk 301 is prone to deformation and skew, resulting in poor pressure consistency of the rotating disk 301 on the balls.

[0024] In Embodiment 2, based on Embodiment 1, the lateral drive component 6 includes: a guide shaft 601 and a reversing slider 602. The guide shaft 601 is threadedly connected to the rotating disk 301; the reversing slider 602 is slidably mounted on the guide shaft 601; the reversing slider 602 slidably fits against the bottom of the rotating disk 301; a rubber pad is provided at the bottom of the reversing slider 602; the rubber pad at the bottom of the reversing slider 602 is flush with the groove at the bottom of the rubber strip 302; the lateral drive component 6 further includes: a toggle post 603, which is fixedly mounted on the bottom of the reversing slider 602; the toggle post 603... Located within the guide groove 1021, the lateral drive component 6 can automatically control the lateral rotation of the balls during the rotation of the rotating disk 301, further rubbing the balls to improve the overall grinding performance. The structure is simple to control and can solve the problems of single rotation direction of the balls and poor overall grinding performance in traditional raceway grinding. The traditional single-disc structure can only drive the balls to rotate in one direction, and the contact area between the balls and the raceway is fixed. In the long term, only a local area participates in grinding, resulting in grinding blind spots and uneven grinding. The multi-directional compound rotation changes the ball movement trajectory from a single circumferential direction to a multi-directional trajectory.

[0025] The working principle of this embodiment is as follows: During ball bearing grinding, balls are first placed in each grinding groove 4011. Grinding fluid is then used to penetrate between the grinding groove 4011 and the balls for fine grinding. Next, the extrusion screw 202 is manually rotated, causing the rotating disk 301 to move downwards and press down on one ring of balls. Simultaneously, the spacing of the grinding mounting posts 401 is equal, ensuring even pressure on the bottom of the rotating disk 301. Further tightening of the extrusion screw 202 compresses the pressure spring 204, controlling the degree of compression of the pressure spring 204. This controls the pressure applied by the rotating disk 301 to the ball bearings. When the rotating disk 301 presses down on the ball bearings, one rotation of the grinding mounting post 401 will compress the return spring 402, and the grinding mounting post 401 will be pressed down together to the position switch 1011. Only then can the drive motor 201 be energized and started normally. Conversely, if no ball bearings are placed in a certain grinding groove 4011, the corresponding grinding mounting post 401 cannot be pressed down by the rotating disk 301, the corresponding position switch 1011 cannot be energized, and the grinding drive operation cannot be performed normally. To prevent uneven pressure on the bottom of the rotating disk 301 when the pressure spring 204 presses the rotating disk 301 when no balls are placed in the grinding groove 401, thus affecting the consistency of the downward pressure of the rotating disk 301 on the balls below; when the drive motor 201 drives the drive cylinder 2011 to rotate, the drive cylinder 2011 can drive the rotating disk 301 on the drive sleeve 3011 to rotate together, and the rubber strip 302 can be used to drive the balls to rotate by friction. During the rotation of the balls in the grinding groove 4011, the liquid inlet pipe 104 An external grinding fluid pump supplies grinding fluid in real time and discharges it into the collection tank 3012. The grinding fluid is then discharged through the through hole in the collection tank 3012 and flows into the guide tank 4012 to fully participate in ball grinding. At the same time, the grinding fluid and the grinding iron filings are discharged in real time from the leakage hole 4013. The discharge tank 1023 connected to the leakage hole 4013 ensures that the grinding fluid is discharged into the guide tank 1021 and then discharged from the discharge hole 1022. After accumulating in the outer discharge ring 103, the waste liquid is discharged from the hose on the outer discharge ring 103.

[0026] When the rotating disk 301 rotates, it drives the rubber strip 302 to rotate together. The cleaning spring 502 will elastically push the scraping slide plate 501 to move upward and fit against the bottom of the rubber strip 302 to perform scraping and cleaning work, avoiding excessive iron filings and impurities adhering to the bottom of the rubber strip 302. When the rotating disk 301 rotates, it will also drive the actuating column 603 to move within the guide groove 1021. Utilizing the wave-shaped structure of the guide groove 1021, the actuating column 603 can be guided to move the reversing slider 602 back and forth. As the rotating disk 301 rotates, the reversing slider 602 will rotate laterally against the friction ball, adjusting the grinding surface and promoting the improvement of the overall grinding.
