Description

Technical Field

[0001] The present invention relates to the technical field of grinding machines, in particular to a cylindrical grinding machine for bearings. Background Art

[0002] In existing technology, grinding the outer diameter of large bearing rings typically involves a vertical grinder, often using an electromagnetic clamp to secure the bearing. Due to the size and weight limitations of large bearing rings, they are typically hoisted above the grinder's chuck. Multiple lifting points are used to ensure the bearing ring's axis is perpendicular to the chuck's top surface. Then, power is applied to the chuck, securing the bearing to the chuck's surface via electromagnetic attraction.

[0003] However, when hoisting a large bearing ring onto the grinding machine's chuck, the lack of initial positioning and support for the bearing requires operators to spend considerable time and effort adjusting the bearing ring's position on the chuck to align its center axis as closely as possible. This not only increases the time required to adjust the bearing center each time, but also reduces the grinding machine's processing efficiency. Summary of the Invention

[0024] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application. Example

[0026] refer to Figure 1-2, this embodiment proposes a bearing cylindrical grinder, including a base plate 1, a transmission box 101 is provided on the base plate 1, a magnetic chuck 102 is provided on one side of the transmission box 101, and a grinding mechanism 2 is provided on one side of the magnetic chuck 102. It should be noted that during the bearing grinding process, the magnetic chuck 102 and the grinding wheel in the grinding mechanism 2 rotate in opposite directions, that is, one rotates clockwise and the other rotates counterclockwise, thereby grinding the outer circle of the bearing. As for how the magnetic chuck 102 adsorbs the bearing, the relevant content has been described in detail in the invention patent with announcement number CN106346322B. Therefore, this embodiment will no longer repeat the prior art.

[0027] Furthermore, a fixed disk 103 is provided on the side of the magnetic chuck 102 away from the transmission box 101, and a first fixed cylinder 104 is fixedly connected to one side of the fixed disk 103. The first fixed cylinder 104 is fixedly connected to the second fixed cylinder 106 through a plurality of connecting frames 105, and the central axis of the first fixed cylinder 104 and the second fixed cylinder 106 coincides with the central axis of the magnetic chuck 102. The outer surfaces of the first fixed cylinder 104 and the second fixed cylinder 106 are connected to a positioning plate 108 through a plurality of first connecting rods 107, and each fixed cylinder 104 is fixed to the second fixed cylinder 106. The positioning plate 108 is circumferentially arranged with the first fixed cylinder 104 as the center, and one end of each first connecting rod 107 is rotatably connected to the outer surface of the corresponding first fixed cylinder 104 and the second fixed cylinder 106, and the other end of the first connecting rod 107 is rotatably connected to the positioning plate 108, and one side of each first connecting rod 107 is inclined from the side of the first fixed cylinder 104 or the second fixed cylinder 106 to the side away from the magnetic chuck 102. An adjustment mechanism is provided on the fixed disk 103 to make each positioning plate 108 open outward or contract inward.

[0028] Before workers install large bearings, they first measure the inner diameter of the bearing's inner circle, and then use an adjustment mechanism to adjust the distance between the two relative positioning plates 108 so that it matches the inner diameter of the bearing's inner circle. Next, the worker uses a crane to lift the bearing, bringing the inner circle of the bearing's outer ring into contact with the surface of each positioning plate 108, and then slowly pushes the bearing along the surface of the positioning plate 108 until it contacts the magnetic chuck 102. Subsequently, the magnetic chuck 102 is energized, so that the bearing is fixed to the surface of the magnetic chuck 102 by electromagnetic attraction. The positioning plates 108 provided can provide preliminary positioning and support for the bearing, greatly reducing the time and effort of the operator in adjusting the position of the bearing ring, thereby improving installation efficiency.

[0029] Specifically, the adjustment mechanism includes a first movable cylinder 3, a second movable cylinder 301, an adjusting screw 302, an adjusting block 303, and several second connecting rods 304 that are rotatably connected to the outer surface of the first movable cylinder 3 and the second movable cylinder 301 on one side, the adjusting screw 302 is rotatably connected to the inside of the first fixed cylinder 104 and the second fixed cylinder 106, and one side of the adjusting screw 302 extends to the outside of the second fixed cylinder 106 and is fixedly connected to the adjusting block 303, the first movable cylinder 3 is arranged between the first fixed cylinder 104 and the second fixed cylinder 106, and is threadedly connected to the adjusting screw 302, the second movable cylinder 301 is arranged on the side of the adjusting screw 302 away from the magnetic chuck 102, and is threadedly connected to the adjusting screw 302, the other side of each second connecting rod 304 is rotatably connected to the positioning plate 108, and one side of each second connecting rod 304 is inclined from the side of the first movable cylinder 3 or the second movable cylinder 301 to the side close to the magnetic chuck 102.

[0030] During operation, a worker uses a tool to rotate the adjustment block 303, which in turn rotates the adjustment screw 302, thereby driving the first movable cylinder 3 and the second movable cylinder 301 to move simultaneously toward the magnetic chuck 102. Simultaneously, the first movable cylinder 3 and the second movable cylinder 301 move one side of the second connecting rod 304, while the other side of the second connecting rod 304 pushes the positioning plate 108 outward. Simultaneously, the first connecting rod 107 rotates clockwise by a certain angle under the action of the positioning plate 108.

[0031] This solution achieves synchronous adjustment of multiple positioning plates 108 through an adjustment screw 302, which is simple and quick to operate. The threaded connection method allows the positioning plates 108 to be locked in any position, enhancing the adaptability of the positioning plates 108 and enabling effective positioning of bearings with different inner diameters.

[0032] Furthermore, this solution tilts one side of each first connecting rod 107 away from the first fixed cylinder 104 or the second fixed cylinder 106 toward the side away from the magnetic chuck 102, and tilts one side of each second connecting rod 304 away from the first movable cylinder 3 or the second movable cylinder 301 toward the side closer to the magnetic chuck 102. This design creates a triangular structure between the first connecting rod 107, the second connecting rod 304, and the adjusting screw 302 when the positioning plate 108 supports the bearing. This improves the supporting capacity and structural strength of the positioning plate 108, enabling it to provide more stable support and positioning for heavier bearings.

[0033] In this embodiment, rolling bearings 305 are provided inside the first fixed cylinder 104 and the second fixed cylinder 106. The adjusting screw 302 is fixedly connected to the inner ring of the rolling bearing 305, and the fixed disk 103 is fixedly connected to the magnetic chuck 102 via a plurality of bolts 306. The provided rolling bearings 305 can effectively reduce the frictional resistance during the rotation of the adjusting screw 302, improve the flexibility and stability of the rotation, and facilitate the operation of workers. Secondly, the fixed disk 103 is fixedly connected to the magnetic chuck 102 via a plurality of bolts 306. This connection method facilitates the installation and removal of the fixed disk 103. At the same time, workers can replace the fixed disk 103 of different sizes and the structure thereon for supporting and positioning the bearing as needed to ensure that bearings of different sizes can be effectively positioned. Example

[0034] Based on Example 1, Figure 3-7 In this embodiment, a cooling mechanism for cooling the bearing is provided on the base plate 1. The cooling mechanism includes a filter box 4, a filter screen 401 arranged inside the filter box 4, and a cooling pipe 402. The filter box 4 is arranged on the top of the base plate 1 and is located below the grinding mechanism 2 (that is, below the grinding wheel in the grinding mechanism 2). One side of the cooling pipe 402 is arranged above the grinding mechanism 2, and the other side of the cooling pipe 402 is connected to the bottom of the filter box 4 through a water pump.

[0035] The outlet of cooling pipe 402 should be oriented toward the point in the grinding mechanism 2 where the grinding wheel contacts the outer diameter of the bearing. This effectively reduces the temperature in the grinding area and prevents bearing burns due to high temperatures. Furthermore, the coolant can flush away particulate matter generated during the grinding process and flow into filter box 4 along with the coolant.

[0036] Furthermore, this design allows the coolant to be recycled within the cooling system: The coolant is pumped from filter box 4 to cooling pipe 402 via a water pump, then sprayed onto grinding mechanism 2 via cooling pipe 402 to cool the bearings. The coolant then flows back to filter box 4, carrying impurities generated by grinding. After being filtered by filter screen 401, the coolant is pumped back to cooling pipe 402, thus forming a closed-loop circulation system. This avoids water waste and improves water utilization efficiency. It is worth noting that cooling pipe 402 can also be connected to an external water source.

[0037] In this embodiment, a vibration mechanism is provided inside the filter box 4 to make the filter 401 vibrate up and down. The vibration mechanism includes elastic members 403 arranged at the four corners of the bottom of the filter 401 and a driving component that intermittently compresses the elastic members 403 of the filter 401. Support plates 404 are fixedly connected to the four corners of the bottom of the filter 401 in the filter box 4. One end of each elastic member 403 abuts against the surface of the support plate 404, and the other end of each elastic member 403 abuts against the bottom of the filter 401.

[0038] The vibration mechanism can prevent impurities from accumulating on the filter 401, thereby improving the filtering effect of the filter 401, avoiding frequent replacement of the filter 401 due to clogging by impurities, extending the service life of the filter 401, and reducing production costs.

[0039] Specifically, the driving assembly includes a traction block 5, a rotating shaft 501, and a servo motor 502. The rotating shaft 501 rotates inside the filter box 4 and is arranged at the bottom of the filter screen 401. The servo motor 502 is arranged on the side of the filter box 4, and the output end of the servo motor 502 is fixedly connected to the rotating shaft 501. The traction block 5 is arranged at the bottom of the filter screen 401 and fixedly connected to the bottom of the filter screen 401. An extension portion 503 is provided on one side of the traction block 5. A rotating cylinder 504 is fixedly connected to the side of the rotating shaft 501 close to the traction block 5. The outer surface of the rotating cylinder 504 is provided with a plurality of push rods 505 arranged at intervals, and each push rod 505 is circumferentially arranged with the rotating cylinder 504 as the center of the circle, and the push rod 505 conflicts with the extension portion 503.

[0040] During use, a worker activates the servo motor 502. The output of the servo motor 502 rotates the rotating shaft 501, which in turn rotates the rotating cylinder 504, which in turn rotates the push rod 505. When one side of the push rod 505 contacts the extension 503 on the traction block 5, the push rod 505 drives the extension 503 and the traction block 5 downward. The other side of the traction block 5 moves the filter 401 in the direction of the compressed elastic member 403. When the push rod 505 disengages the extension 503, the elastic members 403 return to their original shape, moving the filter 401 in the opposite direction. Each time the next push rod 505 contacts the extension 503, the action repeats, causing the filter 401 to vibrate, preventing clogging due to excessive accumulation of particulate matter on its surface.

[0041] The driving assembly in this solution only requires the servo motor 502 to rotate in one direction to achieve the up and down vibration of the filter 401, thereby extending the service life of the servo motor 502.

[0042] Furthermore, each push rod 505 is rotatably connected to a pulley 506, and each pulley 506 abuts against the extension 503. The pulley 506 converts sliding friction into rolling friction, reducing wear between the push rod 505 and the traction block 5 (extension 503), increasing the service life of the components, and also making the vibration process of the filter 401 smoother and more stable.

[0043] Secondly, a guide rod 507 is fixedly connected to the top of each support plate 404. The filter screen 401 is slidably connected to each guide rod 507, and each elastic member 403 is sleeved onto the outer surface of the wire rod. The guide rod 507 guides the vibration of the filter screen 401, ensuring that the filter screen 401 remains stable during the up and down vibration process without shifting or shaking, thereby improving the stability and reliability of the vibration mechanism. It also ensures that the elastic member 403 does not shift or misalign during compression and extension, thereby extending the service life of the elastic member 403.

[0044] When grinding the outer diameter of a bearing, abrasive particles from the grinding wheel may remain on the workpiece surface. These particles can affect the contact quality between the grinding wheel and the workpiece, leading to uneven grinding. For example, the presence of particles can cause uneven contact of the grinding wheel in certain areas, resulting in localized over-grinding or under-grinding, affecting the size and surface quality of the workpiece.

[0045] In order to avoid this situation, the present embodiment further provides a cleaning assembly on the bottom plate 1 for cleaning impurities on the bearing surface after grinding, and the cleaning assembly includes an air supply cylinder 6, a piston 601, a cleaning nozzle 602, an air supply pipe 603, a first one-way valve 604, a second one-way valve 605, an air inlet pipe 606, two third connecting rods 607, and a fourth connecting rod 608. The air supply cylinder 6 is fixedly connected to the inside of the filter box 4, and an air supply cavity 609 is provided inside the air supply cylinder 6. The piston 601 is slidably connected to the inside of the air supply cavity 609. The air supply pipe 603 and the air inlet pipe 606 are both connected to the side of the air supply cavity 609 away from the piston 601. The cleaning nozzle 602 is arranged on the magnetic chuck 102 through the support frame 610. At the bottom, the other end of the air supply pipe 603 is connected to the inside of the cleaning nozzle 602, and an opening 611 is provided on the side of the rotating shaft 501 close to the piston 601. Two third connecting rods 607 are respectively arranged on both sides of the opening 611 and are fixedly connected to the rotating shaft 501. One end of the fourth connecting rod 608 is rotatably connected to the two third connecting rods 607, and the other end of the fourth connecting rod 608 is rotatably connected to the piston 601, and the length of the piston 601 is greater than the length of the third connecting rod 607. The first one-way valve 604 is arranged on the air inlet pipe 606, so that the air inlet pipe 606 can only take in air but not discharge air. The second one-way valve 605 is arranged on the air supply pipe 603, so that the air supply pipe 603 can only discharge air but not take in air.

[0046] By setting up a cleaning component, particles and impurities on the outer cylindrical surface of the bearing after grinding can be effectively removed, thereby ensuring the uniformity of the outer cylindrical surface of the bearing during the next grinding, and further ensuring the final product quality of the bearing.

[0047] When the rotating shaft 501 rotates under the action of the servo motor 502, the rotating shaft 501 drives the third connecting rod 607 to rotate, and the third connecting rod 607 drives one side of the fourth connecting rod 608 to rotate, thereby causing the other end of the fourth connecting rod 608 to drive the piston 601 to move in the air supply chamber 609. When the piston 601 moves toward the rotating shaft 501, the volume of the air supply chamber 609 increases, the first one-way valve 604 opens, the second one-way valve 605 closes, and the air intake pipe 606 starts to take in air and fills the air supply chamber 609; when the piston 601 moves in the direction away from the rotating shaft 501, the volume of the air supply chamber 609 decreases, and the piston 601 pushes the gas in the air supply chamber 609 into the air supply pipe 603. At this time, the second one-way valve 605 opens, the first one-way valve 604 closes, and the gas is transported to the cleaning nozzle 602 through the air supply pipe 603 and ejected by the cleaning nozzle 602 to perform jet cleaning on the ground bearing surface to remove surface impurities and debris, thereby improving the cleanliness and surface quality of the bearing.

[0048] The cleaning component in this solution utilizes the power source of the rotating shaft 501 to achieve the cleaning function, without the need for an additional power device, thereby achieving effective utilization of resources and achieving energy-saving and environmental protection effects.

[0049] Furthermore, traditional contact cleaning may require the use of various specialized cleaning tools, which wear out during use and require regular replacement, increasing production costs. Non-contact jet cleaning utilizes only the airflow generated by the cleaning components, eliminating the need for additional contact cleaning tools and reducing replacement costs.
