Description

Technical Field

[0001] This invention relates to the field of bearing processing technology, and more specifically, to a surface grinding device for bearing processing. Background Technology

[0002] Bearings are essential components in modern machinery. Their primary function is to support rotating parts, reduce friction during movement, and ensure rotational accuracy. Due to variations in manufacturing precision and material uniformity, even bearings made of the same material, of the same size, from the same batch, and used under the same operating conditions can have different lifespans. Sliding bearings do not have inner or outer rings or rolling elements and are generally made of wear-resistant materials. They are commonly used in low-speed, light-load mechanical rotating parts where lubrication and maintenance are difficult.

[0003] Chinese Patent Application No. CN202311284254.6 discloses a surface grinding device for bearing processing, including a processing platform and left and right processing blocks symmetrically arranged on the processing platform. Each processing block includes a drive mechanism, a support and positioning mechanism, and a grinding mechanism. The support and positioning mechanism positions the bearing, the drive mechanism drives the support and positioning mechanism to move left and right and rotate, and the grinding mechanism elastically presses against the bearing. The support and positioning mechanism drives the bearing to rotate synchronously, and the grinding mechanism grinds the bearing synchronously from both sides. This invention's surface grinding device for bearing processing symmetrically arranges grinding mechanisms on both sides of the bearing. The support and positioning mechanism, which fixes the bearing, drives the bearing to rotate, allowing the grinding mechanism to grind the bearing synchronously from both sides. This is convenient to operate, eliminates the need to adjust the bearing position, and ensures consistency in processing on both sides of the bearing, reducing processing errors. However, this patent cannot grind the inner and outer rings of the bearing simultaneously, increasing grinding time and affecting work efficiency.

[0004] Currently, when grinding the surface of a bearing, it is usually done one side at a time, and the bearing position needs to be changed back and forth during the grinding process. This results in poor overall grinding efficiency and prevents the outer surface of the inner ring of the bearing from being ground simultaneously, increasing grinding time, reducing grinding efficiency, and causing inaccurate grinding, which leads to poor overall aesthetics, reduces overall processing quality, and makes it inconvenient for practical use.

[0005] Therefore, a surface grinding device for bearing processing is invented to solve the above problems. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a surface grinding device for bearing processing, which enables the bearing to be stably limited by the first limiting mechanism and the second limiting mechanism at the same time, and drives it to rotate stably on the same vertical plane at the same time, thereby achieving uniform and stable switching of the contact position with the grinding head, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a surface grinding device for bearing processing, comprising a first limiting mechanism, a second limiting mechanism provided on one side of the first limiting mechanism, an adjusting mechanism slidably connected to the bottom of both the first limiting mechanism and the second limiting mechanism, and a grinding mechanism fixedly connected to the top of both the first limiting mechanism and the second limiting mechanism.

[0008] The second limiting mechanism includes a second movable frame, a second rotating shaft rotatably connected inside the second movable frame, a second limiting disk fixedly connected to one end of the second rotating shaft, second limiting grooves on both sides of the second limiting disk, and multiple second abrasive plates slidably connected to the inner cavity of the second limiting disk, with second positioning blocks fixedly connected to both sides of the multiple second abrasive plates, and a third limiting disk rotatably connected to the outer wall of the second rotating shaft, the third limiting disk having an arc-shaped positioning groove slidably connected to the second positioning block inside.

[0009] Preferably, the grinding mechanism includes a support frame fixedly connected to the top of the second movable frame, a fixed frame fixedly connected to the horizontal center line of the support frame, a first threaded rod rotatably connected inside the fixed frame, a first electric telescopic rod slidably connected to the support frame on the outer wall of the first threaded rod, and a grinding head rotatably connected to one end of the first electric telescopic rod.

[0010] Preferably, the first limiting mechanism includes a first movable frame disposed on one side of the second movable frame and parallel to the second movable frame. A first rotating shaft is rotatably connected to one side of the first movable frame. A motor is fixedly connected to one end of the first rotating shaft, and a first limiting plate is fixedly connected to the other end of the first rotating shaft. Both sides of the first limiting plate are provided with first limiting grooves communicating with its inner cavity. The inner cavity of the first limiting plate is provided with a plurality of first abrasive plates, and both sides of the plurality of first abrasive plates are fixedly connected with first positioning blocks.

[0011] Preferably, the horizontal center lines of the first rotating shaft and the second moving frame are both set on the same horizontal plane, and the centers of the second limiting plate and the first limiting plate are both set at the same point.

[0012] Preferably, a retaining sleeve is fixedly connected to the end of the second positioning block away from the third limiting plate, and the retaining sleeve is engaged with the first positioning block.

[0013] Preferably, the first positioning block is slidably connected to the first limiting groove, and one end of each of the plurality of first positioning blocks is fixedly connected to a telescopic spring, and the plurality of telescopic springs are fixedly connected to the outer wall of the first limiting plate.

[0014] Preferably, the outer wall of the first threaded rod has two threaded grooves with opposite helical directions, and each threaded groove of the first threaded rod is slidably connected to the first electric telescopic rod.

[0015] Preferably, the two abrasive heads provided on the support frame are symmetrically arranged with respect to the horizontal center line of the fixed frame under normal conditions, and the outer wall of the abrasive head is arranged in an arc shape.

[0016] Preferably, the adjustment mechanism includes an anti-slip seat that is slidably connected to the bottom of the first movable frame and the second movable frame. A fixing block is fixedly connected to the vertical center line of the anti-slip seat. Both ends of the fixing block are rotatably connected to second threaded rods. The first movable frame and the second movable frame are both engaged with the outer wall of the second threaded rods, and the thread directions of the second threaded rods on both sides of the fixing block are arranged in opposite directions.

[0017] Preferably, the fixed block has two second electric telescopic rods fixedly connected inside, and the top of each of the two second electric telescopic rods is rotatably connected to a grinding roller.

[0018] The technical effects and advantages of this invention are as follows:

[0019] This invention uses a first positioning block and a retaining sleeve to interlock, maintaining a fixed connection between the second limiting plate and the first limiting plate. This provides simultaneous support and limiting of the bearing, allowing the grinding head to grind both sides of the bearing at the same time. This results in more symmetrical grinding angles on both sides, enabling rapid and even grinding of the corners. It avoids the problem of inconsistent edge wear caused by the inability to switch edges at a stable and uniform speed during traditional handheld bearing grinding. It also simplifies the tedious process of repeatedly disassembling and reassembling the bearing after it has been fixed and ground by the traditional fixed assembly. This improves the overall efficiency and quality of bearing grinding, ensures the relative stability of the bearing, and results in high precision in bearing grinding.

[0020] By adjusting the interaction between the grinding head, grinding roller, first grinding disc, and second grinding disc on the bearing, a single device can grind the inner or outer wall of the bearing without changing the equipment or components. This avoids errors caused by repeated positioning, thereby improving grinding efficiency and ensuring the stability and reliability of the bearing.

[0021] The bearing is polished by rotating the first and second grinding discs, which simultaneously drive the bearing to rotate. The speed difference between the rotation of the first and second grinding discs and the rotation of the bearing allows for simultaneous polishing of both the outer and inner walls of the bearing. This saves polishing time, improves polishing efficiency, and makes full use of the bearing polishing equipment to achieve the best polishing effect. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0033] Traditional bearing grinding equipment typically grinds the edges and corners of bearings one side at a time, and the bearing position needs to be changed back and forth during the grinding process. It cannot grind both sides at the same time, which leads to inconsistent grinding of the bearing edges and corners and reduces the overall grinding efficiency.

[0034] Reference Figure 1-4 As shown, the present invention provides a surface grinding device for bearing processing, including a first limiting mechanism 1, a second limiting mechanism 2 provided on one side of the first limiting mechanism 1, an adjusting mechanism 4 slidably connected to the bottom of both the first limiting mechanism 1 and the second limiting mechanism 2, and a grinding mechanism 3 fixedly connected to the top of both the first limiting mechanism 1 and the second limiting mechanism 2. In use, the bearing 46 is placed on the top of the adjusting mechanism 4 and is clamped between the first limiting mechanism 1 and the second limiting mechanism 2.

[0035] The second limiting mechanism 2 includes a second movable frame 21, a second rotating shaft 22 is rotatably connected inside the second movable frame 21, a second limiting disk 23 is fixedly connected to one end of the second rotating shaft 22, a second limiting groove 24 is provided on both sides of the second limiting disk 23, and a plurality of second abrasive plates 25 are slidably connected to the inner cavity of the second limiting disk 23. A second positioning block 28 that is slidably connected to the second limiting groove 24 is fixedly connected to both sides of the plurality of second abrasive plates 25. A third limiting disk 26 is rotatably connected to the outer wall of the second rotating shaft 22. A retainer 29 is fixedly connected to the end of the second positioning block 28 away from the third limiting disk 26. An arc-shaped positioning groove 27 that is slidably connected to the second positioning block 28 is provided inside the third limiting disk 26. Under normal conditions, the plurality of second positioning blocks 28 move and stay on the inner wall of the arc-shaped positioning groove 27 near the center of the third limiting disk 26.

[0036] When the third limiting disk 26 rotates as a whole, the second positioning block 28 moves along the trajectory of the deflected arc-shaped positioning groove 27, causing the second positioning block 28 to push the second grinding plate 25 to move up and down inside the second limiting disk 23. This allows the bearing 46 to be suspended and supported by the second grinding plate 25 and limited in the outer circumferential direction of the second limiting disk 23. Furthermore, it can be freely adjusted according to the change in the inner diameter of the bearing 46, adapting to bearings 46 of different diameters and improving the utilization rate of the bearing 46 grinding equipment.

[0037] At the same time, combined Figure 4As shown, the grinding mechanism 3 includes a support frame 31 fixedly connected to the top of the second movable frame 21. A fixed frame 32 is fixedly connected to the horizontal center line of the support frame 31. A first threaded rod 33 is rotatably connected inside the fixed frame 32. The outer wall of the first threaded rod 33 has two threaded grooves with opposite spiral directions. A first electric telescopic rod 34 is engaged with the outer wall of the first threaded rod 33 and slidably connected to the support frame 31. The threaded groove of each first threaded rod 33 is slidably connected to the first electric telescopic rod 34. A grinding head 35 is rotatably connected to one end of the first electric telescopic rod 34.

[0038] In practical use, after the bearings 46 with different inner diameters are supported and limited by the adjustable-length second abrasive discs 25, the distance between the two first electric telescopic rods 34 and the corresponding abrasive heads 35 can be synchronously and in opposite directions by rotating the first threaded rod 33. This allows for the grinding of the edges and corners of the inner and outer rings of bearings 46 with different thicknesses. By adjusting the distance between the two abrasive heads 35, they can be respectively fitted to the edges and corners of the inner and outer rings, allowing for simultaneous grinding of the edges and corners of the inner and outer rings of the bearing 46, improving overall processing efficiency. Furthermore, by causing the bearing 46 to rotate as a whole by the multiple second abrasive discs 25, the corresponding abrasive heads 35 can be positioned on the shaft. The bearing 46 is supported on both sides, making the grinding of the corners of the bearing 46 more symmetrical, improving the overall processing quality, and making the grinding speed of the corners of the bearing 46 faster and more symmetrical. At the same time, the two grinding heads 35 set on the support frame 31 are symmetrically set with respect to the horizontal center line of the fixed frame 32 under normal conditions, and the outer wall of the grinding head 35 is set in an arc state. The purpose of this setting is that when the length is adjusted by activating the first electric telescopic rod 34, the contact range between the grinding head 35 and the corners of the bearing 46 can be changed, thereby changing the grinding angle of the corners of the bearing 46 synchronously, and thus changing the smoothness of the corners of the bearing 46 synchronously. This makes the overall linkage of the device stronger and more convenient for practical use.

[0039] Synchronous, reference Figure 2-3As shown, the first limiting mechanism 1 includes a first moving frame 101 disposed on one side of the second moving frame 21 and parallel to the second moving frame 21. A first rotating shaft 102 is rotatably connected to one side of the first moving frame 101. A motor 103 for driving the first rotating shaft 102 to rotate is fixedly connected to one end of the first rotating shaft 102. A first limiting plate 104 is fixedly connected to the end of the first rotating shaft 102 away from the motor 103. The interior of the first limiting plate 104 is hollow, and both sides of the first limiting plate 104 are provided with first limiting grooves 105 communicating with its inner cavity. The inner cavity of the first limiting plate 104 is provided with multiple grooves extending vertically towards the center line of the first limiting plate 104. The sliding first abrasive plate 106, and both sides of the multiple first abrasive plates 106 are fixedly connected to the first positioning blocks 107 that are slidably connected to the first limiting groove 105. The sleeve 29 is engaged with the first positioning blocks 107. The first positioning blocks 107 are slidably connected to the first limiting groove 105. One end of the multiple first positioning blocks 107 is fixedly connected to the telescopic springs 108. The multiple telescopic springs 108 are fixedly connected to the outer wall of the first limiting plate 104. The horizontal center lines of the first rotating shaft 102 and the second moving frame 21 are both set on the same horizontal plane. The centers of the second limiting plate 23 and the first limiting plate 104 are both set at the same point.

[0040] In use, by engaging multiple first positioning blocks 107 with the retaining sleeve 29, the second limiting disc 23 and the first limiting disc 104 are fixedly connected. When the second positioning block 28 moves by rotating the third limiting disc 26, the retaining sleeve 29 synchronously drives the first positioning block 107 to rotate. The first positioning block 107 drives the telescopic spring 108 to move, which in turn allows the first abrasive plate 106 to extend and adjust synchronously with the second abrasive plate 25, and then synchronously and stably limit it on the inner wall of the bearing 46. This ensures that the horizontal centerline of the bearing 46 remains horizontal, allowing the bearing 46 to rotate stably during the grinding process through the limiting mechanisms 1 and 2, and keeping its vertical centerline horizontal. The center line always remains on the same vertical line. When the motor 103 starts and drives the first rotating shaft 102 to rotate, the first limiting plate 104 can simultaneously drive the second limiting plate 23 to rotate. This causes the first grinding plate 106 and the second grinding plate 25 to simultaneously drive the bearing 46 to rotate stably. This allows the grinding head 35 to grind both sides of the bearing 46 at the same time, making the grinding angles on both sides more symmetrical. This allows for quick and even grinding of the corners, avoiding the problem of inconsistent wear on the corners caused by the inability to change sides at a stable and uniform speed during the traditional handheld bearing 46 grinding process. It also simplifies the tedious process of repeatedly disassembling and reassembling the bearing 46 after it has been fixed in place for grinding, thus improving the overall efficiency and quality of grinding the bearing 46 and making the grinding of the bearing 46 more precise.

[0041] This invention uses the first positioning block 107 and the retaining sleeve 29 to engage with each other, so that the second limiting plate 23 and the first limiting plate 104 are fixedly connected, and the bearing 46 is supported and limited simultaneously. This allows the grinding head 35 to grind both sides of the bearing 46 at the same time, making the grinding angles on both sides more symmetrical. It can quickly and evenly grind the corners, avoiding the problem of inconsistent edge-changing speed in the traditional hand-held bearing 46 grinding process, which leads to different degrees of edge wear. It also simplifies the tedious process of repeatedly disassembling and reassembling the bearing 46 after it is fixed for grinding with the traditional fixed component, improving the overall working efficiency and quality of grinding the bearing 46, ensuring the relative stability of the bearing 46, and making the grinding of the bearing 46 highly accurate. Example 2

[0042] Further improvements have been made to the above embodiments. In the traditional bearing 46 grinding device, the grinding of the outer or inner wall of the bearing 46 is not carried out on the same equipment, which makes the grinding process of the bearing 46 more complicated. It is troublesome to change equipment or components. Moreover, there are positioning errors when changing equipment, which affects the processing and grinding efficiency of the bearing 46.

[0043] Reference Figure 5-8 As shown, the adjustment mechanism 4 includes an anti-slip seat 41 disposed at the bottom of the first movable frame 101 and the second movable frame 21. The first movable frame 101 and the second movable frame 21 are always symmetrically arranged about the vertical center line of the anti-slip seat 41. A fixing block 42 is fixedly connected at the vertical center line of the anti-slip seat 41. A second threaded rod 43 is rotatably connected to both ends of the fixing block 42. The first movable frame 101 and the second movable frame 21 are both engaged with the outer wall of the second threaded rod 43. The thread directions of the second threaded rods 43 on both sides of the fixing block 42 are opposite. Two second electric telescopic rods 45 are fixedly connected inside the fixing block 42. A grinding roller 44 is rotatably connected to the top of each of the two second electric telescopic rods 45.

[0044] When the two second threaded rods 43 rotate, the second moving frame 21 and the first moving frame 101 can move synchronously in opposite directions on their outer walls. This causes the corresponding second abrasive pad 25 and the first abrasive pad 106 to move synchronously towards the vertical centerline of the anti-slip seat 41, so that the first positioning block 107 and the sleeve 29 engage with each other. The bearing 46 is stably limited at the top of the anti-slip seat 41. After being stably limited by the first limiting mechanism 1 and the second limiting mechanism 2, the bearing 46 can be perpendicular to the ground. When grinding the bearing 46, the bearing 46 can be ground accurately.

[0045] When the outer wall of bearing 46 needs to be polished, after bearing 46 is stably limited by the first limiting mechanism 1 and the second limiting mechanism 2, the first abrasive plate 106 and the second abrasive plate 25 are tightly attached to the inner wall of bearing 46. By activating the second electric telescopic rod 45 to move upward, the grinding roller 4 is attached to the outer wall of bearing 46. At this time, when the motor 103 drives the first rotating shaft 102 to rotate, the first limiting plate 104 can synchronously drive the second limiting plate 23 to rotate as a whole, so that bearing 46 rotates as a whole. This allows bearing 46 to rotate stably on the outer wall of grinding roller 44 and rub against it stably, thereby simultaneously polishing the outer wall of bearing 46.

[0046] When it is necessary to polish the inner wall of the bearing 46, the two second threaded rods 43 are rotated to make the two grinding heads 35 on both sides fit and fix the bearing 46. At the same time, the grinding roller 44 is tightly fitted to the outer wall of the bearing 46 to support the bearing 46 and prevent the bottom of the bearing 46 from moving. At this time, the grinding head 35 and the grinding roller 44 support and limit the bearing 46. Then, the third limiting plate 26 is rotated to adjust the first grinding plate 106 and the second grinding plate 25 to contact the inner wall of the bearing 46. When the motor 103 is rotated, the first grinding plate 106 and the second grinding plate 25 rotate to polish the inner wall of the bearing 46, thereby achieving the polishing of the inner wall of the bearing 46.

[0047] By adjusting the interaction between the grinding head 35, grinding roller 44, first grinding disc 106 and second grinding disc 25 on the bearing 46, a single device can grind the inner or outer wall of the bearing 46 without changing the equipment or components. This avoids errors caused by repeated positioning, thereby improving grinding efficiency and ensuring the stability and reliability of the bearing 46. Example 3

[0048] Further improvements have been made to the above embodiments. In the traditional bearing 46 grinding device, the outer and inner walls of the bearing 46 cannot be ground simultaneously during the grinding process. Grinding the outer and inner walls of the bearing 46 separately reduces the working efficiency of the bearing 46 grinding.

[0049] Reference Figure 8-9As shown, when both the outer and inner walls of the bearing 46 need to be polished simultaneously, the first abrasive disc 106 and the second abrasive disc 25 are adjusted to contact the bearing 46, and the abrasive heads 35 and the grinding rollers 44 on both sides are also adjusted to contact the bearing 46, thus supporting the bearing 46. When the first rotating shaft 102 is rotated by the motor 103, the first abrasive disc 106 and the second abrasive disc 25 rotate to polish the bearing 46, and also drive the bearing 46 to rotate. As the bearing 46 rotates, it rubs against the abrasive heads 35 and the grinding rollers 44 on both sides, achieving the desired polishing effect on the shaft. The bearing 46's edges, outer wall, and inner wall are polished simultaneously. Because the first abrasive disc 106 and the second abrasive disc 25 do not fit tightly against the inner wall of the bearing 46, their rotation can polish the inner wall of the bearing 46 and also drive the bearing 46 to rotate. The speed difference between the rotation of the first abrasive disc 106 and the second abrasive disc 25 and the rotation of the bearing 46 enables simultaneous polishing of the outer and inner walls of the bearing 46. This saves polishing time, improves polishing efficiency, makes full use of the bearing 46 polishing equipment, and achieves the best polishing effect.

[0050] The bearing 46 is polished by rotating the first abrasive disc 106 and the second abrasive disc 25. At the same time, the bearing 46 rotates. The speed difference between the rotation of the first abrasive disc 106 and the second abrasive disc 25 and the rotation of the bearing 46 can achieve simultaneous polishing of the outer and inner walls of the bearing 46. This saves polishing time, improves polishing efficiency, makes full use of the bearing 46 polishing equipment, and achieves the best polishing effect.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
