Therefore, after grinding is completed, the grinding work is sequentially continued without moving the long connecting plate, the scraps in the inner part of the bearing outer groove are accurately sucked out through the circumferentially rotating adsorption shell attached to the bearing, so as to eliminate the scraps mixed in the rollers and avoid wear problems of the rollers.

Description

Technical Field

[0001] This invention belongs to the field of ultra-precision machining technology, specifically an ultra-precision machining tool for the outer groove end face of a high-speed spindle bearing. Background Technology

[0002] The outer diameters of both the inner and outer rings of the bearing are assembly surfaces, which require ultra-precision machining. The outer diameter ultra-precision machine has two synchronously rotating idler rollers. The inner and outer rings are placed between the two idler rollers, and an oilstone presses slightly on the outer diameter from above. The continuously rotating idler rollers drive the product to rotate continuously, thereby completing the ultra-precision process.

[0003] The existing high-precision high-speed spindle bearing outer groove end face ultra-precision machine (publication number CN221088569U) can fix bearings of different sizes through its clamping plate. However, when its groove dressing tool processes the outer groove end face of the bearing, the metal shavings generated by grinding are easy to remain inside the bearing. This causes the bearing rollers to generate strong friction due to the shavings during operation, which not only seriously affects the stability of the bearing, but also leads to a significant reduction in the service life of the bearing rollers. Therefore, improvements are needed. Summary of the Invention

[0004] To address the problem of debris easily getting into the outer groove end face of bearings during existing grinding processes, the technical solution adopted in this invention is: an ultra-precision mill for the outer groove end face of high-speed spindle bearings, comprising:

[0005] Support components;

[0006] A flip-up protective cover is located on top of the support component, and an operation screen is provided on the front of the flip-up protective cover;

[0007] The bearing is machined and installed inside the support component;

[0008] Clamping components are symmetrically arranged on the upper and lower sides of the supporting component;

[0009] The grinding components are symmetrically arranged on the front and rear sides of the bearing to perform grinding on the outer groove end face of the bearing.

[0010] The grinding component includes:

[0011] An adjustable base plate, wherein a pushing component is provided on the top of the adjustable base plate;

[0012] A vertical connecting plate, the bottom of which is slidably connected to the interior of the propulsion component;

[0013] The main motor is located at the top of the vertical connecting plate, and a long connecting plate is sleeved on the outer surface of the main motor shaft;

[0014] A secondary motor, the outer surface of which is fixedly connected to one end of the inner cavity of the long connecting plate through a socket, and a grinding head is inserted into the outer surface of the secondary motor shaft. The appropriate grinding head is selected according to the outer groove end face of the bearing to be repaired.

[0015] The adsorption shell has its outer surface engaged with one side of the outer surface of the long connecting plate, and the grinding head extends to the outside of the adsorption shell through a through-hole. The adsorption shell can use an internal pump to adsorb the debris scraped off by the grinding head into the shell.

[0016] Furthermore, the clamping component includes:

[0017] A pressure plate is provided with insert connecting plates evenly arranged on the back of the outer surface of the pressure plate;

[0018] A vertical guide shell, the top of which is inserted into the inner cavity of the lower pressure plate, and a solid push plate is slidably connected to the inner wall of the vertical guide shell. A pressure control machine is provided at the top of the inner cavity of the vertical guide shell.

[0019] The modified clamping plate is set at the bottom of the solid push plate to directly clamp the outer surface of the bearing being processed. The support component below is also equipped with a vertical guide shell, a solid push plate and a modified clamping plate corresponding to the lower pressure plate, so as to fix the bearing being processed vertically. When placing the bearing being processed, first place the bearing being processed on the modified clamping plate at the bottom.

[0020] Furthermore, the modified clamp includes:

[0021] An arc-shaped pressure plate, wherein the top of the inner cavity of the arc-shaped pressure plate is uniformly provided with an inlet, and the front and rear sides of the outer surface of the arc-shaped pressure plate are symmetrically provided with receiving grooves;

[0022] The contact buttons are evenly distributed in the middle of the lower surface of the arc-shaped pressure plate, and the bottom of the contact buttons is provided with auxiliary balls. The contact buttons indirectly apply pressure to the side of the outer hub of the bearing through the auxiliary balls.

[0023] Furthermore, the modified clamp also includes:

[0024] The segmented slide bar has one end of its air inlet connected to the inner cavity of the arc-shaped pressure plate via a receiving groove.

[0025] Side clamps, the outer surface of which is inserted into the end of the segmented slide bar away from the arc-shaped pressure plate. The vertical guide shell, through the internal pressure control machine, pressurizes the inlet of the arc-shaped pressure plate through the internal opening of the solid push plate, thereby indirectly pressurizing the inside of the segmented slide bar, causing the outer shell of the segmented slide bar to slide outward, thereby pulling open the side clamps on both sides.

[0026] Embedded balls are evenly distributed in the inner cavity of the side clamping plate through embedded grooves, and the outer surface of the embedded balls is pressed against the outer surface of the machined bearing. The side clamping plate applies pressure to the side of the bearing outer hub through the embedded balls.

[0027] Furthermore, the support component includes:

[0028] A planar support plate, wherein a limiting frame is provided on the upper surface of the planar support plate, and one end of the adjusting base plate is fixedly connected to the inner wall of the limiting frame;

[0029] The adsorption inner plate is evenly distributed within the cavity of the planar support plate;

[0030] A vertical guide plate, the bottom of which is fixedly connected to the upper surface of the planar support plate, and a guide groove is provided on the upper part of the vertical guide plate;

[0031] The guide roller shaft has its outer surface rotatably connected to the top of the inner cavity of the vertical guide plate. Both ends of the guide roller shaft extend to the outside of the vertical guide plate and are inserted into the inner cavity of the flip-over protective cover.

[0032] Furthermore, the propulsion component includes:

[0033] A guide box, the bottom of which is engaged with the upper surface of an adjusting base plate;

[0034] The built-in transmission belt has its outer surface rotatably connected to the bottom of the inner wall of the guide box. Rotating rods are symmetrically arranged on both sides of the inner wall of the built-in transmission belt, and both ends of the rotating rods are inserted into the inner wall of the guide box. The built-in transmission belt rotates through the internal rotating rods, thereby driving the upper vertical connecting plate to slide.

[0035] The sealing spring strips are symmetrically arranged inside the guide box. One end of the sealing spring strip is inserted into the inner cavity of the guide box, and the other end of the sealing spring strip is fixedly connected to the outer surface of the vertical connecting plate. When the vertical connecting plate slides, it simultaneously drives the sealing spring strips on both sides to slide, thereby ensuring that the top position of the guide box is always in a relatively sealed state.

[0036] Furthermore, the vertical connecting plate includes:

[0037] A hollow housing, the bottom end of which is inserted into the outer surface of the built-in transmission belt;

[0038] The sliding retaining ring has its inner walls on both sides slidably connected to the top of the hollow housing cavity. The sliding retaining ring is used to hold the outer surface of the main motor.

[0039] Elastic inner pads are symmetrically arranged on both sides of the inner wall of the sliding ring;

[0040] An internal connecting plate is provided, the top of which is inserted into the bottom of the outer surface of the sliding retaining ring.

[0041] The guide base box has its outer surface fixedly connected to the inner wall of the hollow shell. The bottom end of the built-in connecting plate is slidably connected to the inner wall of the guide base box. Sensors are evenly arranged on the outer surface of the guide base box, and the sensors extend to the outside of the hollow shell. When the main motor drives the sliding ring to slide, it will press the pressure sensor at the bottom of the guide base box through the built-in connecting plate.

[0042] The beneficial effects of this invention are as follows:

[0043] 1. This device can perform a circular grinding operation on the outer groove end face of the bearing using grinding heads adapted on both sides. This grinding removes rough surfaces and impurities from the inner surface of the bearing's outer groove, making the outer groove end face smoother. However, the metal shavings generated during grinding can easily remain inside the bearing, causing wear on the rollers inside. Therefore, after grinding is completed, without moving the long connecting plate, the grinding operation continues, and the shavings inside the bearing's outer groove are precisely sucked out by the suction shell that rotates around the bearing, thereby eliminating the shavings mixed in with the rollers and preventing roller wear.

[0044] 2. The device uses modified clamping plates on the upper and lower sides to limit and hold the machined bearing. Since the parts that directly contact the outer hub of the bearing during the clamping process are all self-rotating ball structures, the outer surface of the bearing will not wear or scratch due to strong friction with the modified clamping plates when the bearing rotates with the cutting head. The side clamping plates on both sides can further prevent the bearing from jumping and disengaging, thus improving the stability of the clamping.

[0045] 3. When clamping the bearing, the arc-shaped pressure plates on the upper and lower sides will judge the pressing force on the bearing through the contact button at the shaft center, so that the pressing force is kept within an appropriate range. This avoids the problem of the bearing being subjected to large squeezing force and causing hub deformation due to the bearing sliding too far down the top plate. The side clamps on both sides can adjust the spacing with the extension and retraction of the segmented slide rod, so it can be adapted to bearings of different models and thicknesses and effectively clamp them.

[0046] 4. When the long connecting plate rotates, if the top of the grinding head comes into contact with and is pressed against the inner wall of the bearing, the grinding head will be driven by the counter-pushing force to slide relative to the hollow housing by the main motor and the sliding retaining ring. At this time, the moving internal connecting plate triggers the sensor inside the guide box, and then feeds back to the rotating main motor, causing the main motor to slow down and avoid violent shaking of the long connecting plate when rotating, so that the grinding head will not cause great wear to the bearing during cutting.

[0056] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0057] Example 1, please refer to Figures 1-5 This invention provides a technical solution: a high-speed spindle bearing outer groove end face ultraprecision machine, comprising:

[0058] Support component 1;

[0059] A flip-up protective cover 2 is set on top of the support component 1, and an operation screen 3 is provided on the front of the flip-up protective cover 2;

[0060] Machine the bearing 6 and install it inside the support component 1;

[0061] Clamping components 4 are symmetrically arranged on the upper and lower sides of the support component 1;

[0062] Grinding components 5 are symmetrically arranged on the front and rear sides of the bearing 6 to perform grinding on the outer groove end face of the bearing 6.

[0063] Grinding component 5 includes:

[0064] Adjustable base plate 51, with a pusher component 52 provided on the top of the adjustable base plate 51;

[0065] The bottom of the vertical connecting plate 53 is slidably connected to the inside of the propulsion component 52;

[0066] The main motor 54 is located on the top of the vertical connecting plate 53, and the outer surface of the main motor 54 shaft is fitted with a long connecting plate 55.

[0067] Auxiliary motor 56, the outer surface of auxiliary motor 56 is fixedly connected to one end of the inner cavity of long connecting plate 55 through the plug, and a grinding head 57 is inserted into the outer surface of the shaft of auxiliary motor 56. The appropriate grinding head 57 is selected according to the outer groove end face of the bearing to be repaired.

[0068] The outer surface of the adsorption shell 58 is engaged with one side of the outer surface of the long connecting plate 55, and the grinding head 57 extends to the outside of the adsorption shell 58 through the through hole. The adsorption shell 58 can adsorb the debris scraped off by the grinding head 57 into the shell through the internal pump body.

[0069] Clamping component 4 includes:

[0070] The top plate 41 is pressed down, and the back of the outer surface of the top plate 41 is evenly provided with insertion connecting plates 42;

[0071] A vertical guide shell 43 is inserted into the inner cavity of the lower pressure plate 41 at its top, and a solid push plate 44 is slidably connected to the inner wall of the vertical guide shell 43. A pressure control machine is provided at the top of the inner cavity of the vertical guide shell 43.

[0072] The modified clamping plate 7 is set at the bottom of the solid push plate 44 and directly clamps the outer surface of the processed bearing 6. The support component 1 below is also provided with a vertical guide shell 43, a solid push plate 44 and a modified clamping plate 7 corresponding to the lower pressure plate 41, so as to fix the processed bearing 6 vertically. When placing the processed bearing 6, the processed bearing 6 is first placed on the modified clamping plate 7 at the bottom.

[0073] Modified clamp plate 7 includes:

[0074] The arc-shaped pressure plate 71 has an inlet 72 evenly provided at the top of its inner cavity, and receiving grooves 73 symmetrically provided on the front and rear sides of its outer surface.

[0075] Contact buttons 74 are evenly distributed in the middle of the lower surface of the arc-shaped pressure plate 71, and auxiliary balls are provided at the bottom of the contact buttons 74. The contact buttons 74 are indirectly pressurized to the side of the outer hub of the bearing through the auxiliary balls.

[0076] Modified clamp plate 7 also includes:

[0077] The segmented slide bar 75 has one end of its air inlet connected to the inner cavity of the arc-shaped pressure plate 71 via a receiving groove 73.

[0078] Side clamp 76, the outer surface of side clamp 76 is inserted into the end of segmented slide bar 75 away from arc-shaped pressure plate 71. Vertical guide shell 43 presses the inlet 72 of arc-shaped pressure plate 71 through the internal control press of solid push plate 44, thereby indirectly pressurizing the inside of segmented slide bar 75, causing the outer shell of segmented slide bar 75 to slide outward, thereby pulling open the side clamp 76 on both sides.

[0079] The embedded balls 77 are evenly arranged in the inner cavity of the side clamping plate 76 through the embedded groove, and the outer surface of the embedded balls 77 is pressed against the outer surface of the machined bearing 6. The side clamping plate 76 applies pressure to the side of the bearing outer hub through the embedded balls 77.

[0080] Open the flip-top protective cover 2. At this time, the lower pressure plate 41 is at its highest point. Place the machined bearing 6 vertically on the lower modified clamping plate 7. Then, slide the lower pressure plate 41 down through the vertical guide plate 14 so that the upper modified clamping plate 7 is locked at the top of the machined bearing 6. After the machined bearing 6 is fixed, close the flip-top protective cover 2. Control the internal grinding component 5 to grind the outer groove end face of the machined bearing 6 through the external operation screen 3.

[0081] The propulsion components 52 on both sides of the control unit push the vertical connecting plate 53 closer to the bearing 6 being processed. At this time, the grinding heads 57 on both sides of the long connecting plate 55 are inserted into the outer grooves on the front and rear sides of the bearing 6 being processed. Then, the main motor 54 drives the long connecting plate 55 to rotate, and at the same time, the auxiliary motors 56 on both sides drive the corresponding grinding heads 57 to rotate. Then, as the grinding heads 57 sweep across the outer groove of the bearing 6, they grind the end face of the outer groove of the bearing 6 through the friction of rotation. After grinding is completed, the grinding heads 57 stop rotating, but the long connecting plate 55 continues to rotate. As the suction shell 58 sweeps across the end face of the outer groove of the bearing 6, it sucks away the debris stuck in the outer groove of the bearing to prevent debris from getting into the rollers inside the shaft.

[0082] When the modified clamping plate 7 is used to clamp the machining bearing 6, the center part of the outer surface of the bearing hub is pressed against the contact button 74 of the arc-shaped pressure plate 71. Then, the arc-shaped pressure plate 71 pulls the side clamping plates 76 that are pulled apart on both sides closer to the machining bearing 6, so that the embedded balls 77 of the side clamping plate 76 are pressed against the side part of the outer hub of the machining bearing 6. At this time, the machining bearing 6 is clamped and limited by the modified clamping plates 7 on both sides. However, the machining bearing 6 itself can rotate. When the bearing rotates, its outer surface will rotate relative to the auxiliary balls of the contact button 74 and the embedded balls 77 of the side clamping plate 76. Therefore, during the machining process, the outer surface of the machining bearing 6 will not suffer wear due to the large clamping force when rotating.

[0083] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the supporting component 1 includes:

[0084] A planar support plate 11 is provided with a limiting frame 12 on its upper surface, and one end of the adjusting base plate 51 is fixedly connected to the inner wall of the limiting frame 12.

[0085] The adsorption inner plate 13 is evenly arranged in the inner cavity of the planar support plate 11;

[0086] A vertical guide plate 14 is fixedly connected at its bottom to the upper surface of a flat support plate 11, and a guide groove is provided at the top of the vertical guide plate 14.

[0087] The guide roller 15 has its outer surface rotatably connected to the top of the inner cavity of the vertical guide plate 14. Both ends of the guide roller 15 extend to the outside of the vertical guide plate 14, and both ends of the guide roller 15 are inserted into the inner cavity of the flip-over protective cover 2.

[0088] Propulsion component 52 includes:

[0089] The bottom of the guide box 521 is engaged with the upper surface of the adjusting base plate 51;

[0090] The built-in transmission belt 523 has an outer surface that is rotatably connected to the bottom of the inner wall of the guide box 521. Rotating rods are symmetrically arranged on both sides of the inner wall of the built-in transmission belt 523, and both ends of the rotating rods are inserted into the inner wall of the guide box 521. The built-in transmission belt 523 rotates through the internal rotating rods, thereby driving the upper vertical connecting plate 53 to slide.

[0091] The sealing spring strips 522 are symmetrically arranged inside the guide box 521. One end of the sealing spring strip 522 is inserted into the inner cavity of the guide box 521, and the other end of the sealing spring strip 522 is fixedly connected to the outer surface of the vertical connecting plate 53. When the vertical connecting plate 53 slides, it simultaneously drives the sealing spring strips 522 on both sides to slide, thereby ensuring that the top position of the guide box 521 is always in a relatively sealed state.

[0092] Vertical connecting plate 53 includes:

[0093] Hollow housing 531, the bottom end of which is inserted into the outer surface of the built-in transmission belt 523;

[0094] The sliding retaining ring 532 has both sides of its inner wall that are slidably connected to the top of the inner cavity of the hollow housing 531. The sliding retaining ring 532 is used to hold the outer surface of the main motor 54.

[0095] The elastic inner pads 533 are symmetrically arranged on both sides of the inner wall of the sliding retaining ring 532;

[0096] The built-in connecting plate 534 is inserted into the bottom of the outer surface of the sliding retaining ring 532.

[0097] The guide base box 535 has its outer surface fixedly connected to the inner wall of the hollow shell 531. The bottom end of the built-in connecting plate 534 is slidably connected to the inner wall of the guide base box 535. Sensors 536 are evenly arranged on the outer surface of the guide base box 535 and extend to the outside of the hollow shell 531. When the main motor 54 drives the sliding ring 532 to slide, it will press the pressure sensor of the bottom guide base box 535 through the built-in connecting plate 534.

[0098] The support component 1 controls the sliding movement of the pressure plate 41 through the vertical guide plate 14. After the bearing is processed, the modified clamps 7 on the upper and lower sides are pulled apart to remove the processed bearing. Most of the debris that falls off the bearing will fall into the bottom limiting frame 12 and then be sucked away by the adsorption inner plate 13 to achieve recycling.

[0099] The guide box 521 moves the corresponding vertical connecting plate 53 closer to the bearing via the built-in transmission belt 523, so that the grinding head 57 is inserted into the outer groove of the bearing 6. When the long connecting plate 55 rotates, if the top of the grinding head 57 comes into contact with and is pressed against the inner wall of the bearing 6, the grinding head 57 will cause the main motor 54 and the sliding retaining ring 532 to slide relative to the hollow housing 531 due to the counter-pushing force. At this time, the moving built-in connecting plate 534 triggers the sensor 536 inside the guide box 535, and then feeds back to the rotating main motor 54, causing the main motor 54 to slow down, so as to avoid the long connecting plate 55 from vibrating violently when rotating, so that the grinding head 57 will not cause great wear to the bearing during cutting.

[0100] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
