Description

Technical Field

[0001] The invention relates to the technical field of grinding devices, and in particular to a low-noise tapered roller bearing surface treatment device. Background Art

[0002] The grinding device is a kind of precision machining equipment, which is mainly used for grinding the surface of workpieces with high precision and high surface quality. The low-noise tapered roller bearing surface treatment device is a special equipment used to reduce the noise generated by tapered roller bearings during operation. The device uses a variety of technologies and methods to treat the bearing surface to achieve the purpose of reducing noise. In the existing technology, the grinding of the bearing surface usually uses flat grinding equipment, and the circumferential part usually uses centerless grinding equipment. Centerless grinding equipment is a type of machine tool that does not require the axis positioning of the workpiece to perform grinding work. The centerless grinding equipment is mainly composed of three mechanisms: a grinding wheel, an adjusting wheel and a workpiece holder. The grinding wheel is responsible for the actual grinding work, the adjusting wheel controls the rotation of the workpiece and determines its feed speed, and the workpiece holder supports the workpiece during grinding.

[0003] For example, Chinese invention patent publication number CN117340701B discloses a centerless grinding machine for bearing processing. This machine utilizes a variable-diameter support wheel frame to efficiently and conveniently install multiple bearing rings in batches, while also ensuring that the bearing rings are not easily deformed during centerless grinding. However, the varying roundness of the workpiece can significantly impact the grinding process, potentially leading to overgrinding or jamming. Summary of the Invention

[0004] The present invention provides a low-noise tapered roller bearing surface treatment device to solve the problem of over-grinding or jamming caused by different roundness of workpieces during use of existing grinding devices.

[0005] The present invention discloses a low-noise tapered roller bearing surface treatment device employing the following technical solution: The device comprises a frame, a grinding mechanism, and a driving wheel mechanism. The grinding mechanism and the driving wheel mechanism are sequentially arranged on the frame along a first direction.

[0010] Furthermore, the grinding mechanism includes a plurality of connecting frames, which are sequentially arranged along the second direction. The connecting frames are slidably mounted on the frame along the second direction, with each grinding wheel mounted on a connecting frame. Multiple support wheels are rotatably mounted on each connecting frame, with the axes of the support wheels arranged along the second direction. The support wheels are sequentially arranged along the circumference of the grinding wheel, with the support wheels abutting against the grinding wheel.

[0011] Furthermore, the polishing mechanism also includes a plurality of cylinders, which are fixedly mounted on the frame and arranged along the first direction. An elastic member is fixedly mounted on the extended end of each cylinder, and each elastic member is fixedly connected to a connecting frame.

[0012] Furthermore, a low-noise tapered roller bearing surface treatment device further includes a support mechanism, wherein the plurality of workpieces are sequentially distributed on the support mechanism along a second direction. The support mechanism includes a first support frame and two second support frames. The first support frame and the second support frame are both fixedly mounted on a frame. The two second support frames are sequentially distributed along the second direction, with the first support frame disposed between the two second support frames.

[0013] The first support frame includes a first support plate, the upper side of which is stepped, and the height of the stepped first support plate gradually decreases from the first side to the second side of the frame. Each second support frame includes a second support plate and two stopper plates, which are arranged along the second direction. The two stopper plates are sequentially distributed along the first direction, and the second support plates are inclined from the first side to the second side of the frame, gradually approaching the lower side of the frame. The second support plate is positioned between the two stopper plates, and the workpiece is positioned above the first support plate or the second support plate.

[0014] Furthermore, the frame includes a base frame and a movable frame, wherein the base frame is disposed on the ground, and the connecting frame is disposed on the base frame.

[0015] Furthermore, the movable frame includes a first movable plate and a second movable plate, the first movable plate is slidably arranged above the second movable plate along a first direction, the support mechanism is fixedly arranged on the second movable plate, and the driving wheel is rotatably arranged on the first movable frame.

[0017] Furthermore, the driving wheel mechanism also includes a second driving mechanism, the second driving mechanism includes a second driving motor, the second driving motor is fixedly arranged on the movable frame, and the output shaft of the second driving motor is connected to the driving wheel.

[0018] The present invention provides the following beneficial effects: A low-noise tapered roller bearing surface treatment device, utilizing a grinding mechanism and a driven wheel mechanism, places a workpiece between a grinding wheel and a drive wheel, and propels the workpiece from a first side of a frame to a second side of the frame. The grinding wheel and drive wheel rotate, driving the workpiece to grind the workpiece. The workpiece first contacts the grinding wheel near the first side of the frame. Because the linear distance between the grinding wheel and the drive wheel is relatively short, the workpiece's center height is relatively large. The center height is the vertical distance between the center of the workpiece and the line connecting the centers of the first connecting wheel and the drive wheel.

[0019] Although the workpiece's large ovality makes it prone to jitter, its center height is relatively high, making it less likely to get stuck. Therefore, the first connecting wheel reduces the workpiece's ovality, resulting in lower grinding efficiency. Since the multiple grinding wheels gradually move away from the drive wheel from the first side to the second side, as the workpiece moves, the grinding wheels and drive wheel gradually move away from each other, the workpiece gradually moves downward, the center height of the workpiece gradually decreases, the workpiece becomes less prone to jitter, and the workpiece's stability gradually increases, thereby gradually improving the grinding efficiency.

[0020] However, as the center height gradually decreases, the workpiece can easily jam the grinding wheel, causing damage to the grinding wheel, drive wheel, and workpiece. By providing a grinding wheel that can move in a first direction, when the workpiece tends to jam, the workpiece pushes the grinding wheel away from the drive wheel, preventing the workpiece from jamming. Furthermore, by gradually reducing the center height of the workpiece, the workpiece can be ground gradually, preventing over-grinding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 7 As shown, an embodiment of the present invention provides a low-noise tapered roller bearing surface treatment device, comprising a frame 100, a grinding mechanism, and a driving wheel mechanism. The grinding mechanism and the driving wheel mechanism are sequentially arranged on the frame 100 along a first direction. The driving wheel mechanism includes a driving wheel 200, the axis of which is arranged along a second direction. The driving wheel 200 is rotatably arranged on the frame 100 about its own axis. The second direction and the first direction are both horizontal, and the second direction is perpendicular to the first direction. The two sides of the frame 100 along the second direction are respectively a first side and a second side.

[0032] The grinding mechanism includes a plurality of grinding wheels 300 and a plurality of connecting assemblies. The axes of the grinding wheels 300 are arranged along a second direction. The grinding wheels 300 are rotatably mounted on the frame 100 about their axes. The plurality of grinding wheels 300 are sequentially distributed along the second direction. The plurality of grinding wheels 300 gradually move away from the drive wheel 200 from the first side to the second side. Each connecting assembly is disposed between two adjacent grinding wheels 300. The plurality of connecting assemblies allows the plurality of grinding wheels 300 to rotate synchronously and move relative to each other. A workpiece 500 is placed between the grinding wheels 300 and the drive wheel 200. The workpiece 500 moves from the first side of the frame 100 to the second side of the frame 100. Each grinding wheel 300 is pressed by the workpiece 500 and is able to move along the first direction away from the drive wheel 200.

[0033] A workpiece 500 is placed between the grinding wheel 300 and the drive wheel 200 and pushed from the first side of the frame 100 to the second side. The grinding wheel 300 and the drive wheel 200 rotate, driving the workpiece 500 to rotate, and the grinding wheel 300 grinds the workpiece 500. The vertical distance between the center of the workpiece 500 and the line connecting the center of the first connecting wheel 301 and the drive wheel 200 is set as the center height H. The workpiece 500 first contacts the grinding wheel 300 near the first side of the frame 100. Since the linear distance between the grinding wheel 300 and the drive wheel 200 is smaller, the center height H of the workpiece 500 is larger.

[0034] Although the workpiece 500 has a large ovality, making it prone to jitter, its center height is relatively high, making it less likely to get stuck. Consequently, the first connecting wheel 301 reduces the ovality of the workpiece 500, resulting in a lower grinding efficiency. As the multiple grinding wheels 300 gradually move away from the drive wheel 200 from the first side to the second side, the grinding wheels 300 and the drive wheel 200 gradually move away from each other as the workpiece 500 moves, gradually moving the workpiece 500 downward. The center height H of the workpiece 500 gradually decreases, making it less likely to jitter. The stability of the workpiece 500 gradually increases, and thus the grinding efficiency of the workpiece 500 gradually improves.

[0035] However, as the center height H gradually decreases, the workpiece 500 can easily jam the grinding wheel 300, causing damage to the grinding wheel 300, the drive wheel 200, and the workpiece 500. By providing a grinding wheel 300 that can move in a first direction, when the workpiece 500 is about to jam, the workpiece 500 pushes the grinding wheel 300 away from the drive wheel 200, preventing the workpiece 500 from jamming. Furthermore, by gradually reducing the center height of the workpiece 500, the workpiece 500 is gradually ground, preventing over-grinding.

[0036] In this embodiment, the grinding wheel 300 closest to the first side of the frame 100 is a first connecting wheel 301, the grinding wheel 300 closest to the second side of the frame 100 is a second connecting wheel 302, and the remaining grinding wheels 300 are third connecting wheels 303. The grinding mechanism also includes a first drive motor 110, which is fixedly mounted on the frame 100. The output shaft of the first drive motor 110 is fixedly connected to the second connecting wheel 302. The first drive motor 110 drives the second connecting wheel 302 to rotate, and through the connecting assembly, drives the first connecting wheel 301 and the plurality of third connecting wheels 303 to rotate synchronously.

[0037] The mesh counts of the multiple grinding wheels 300 are the same. As the center height H of the workpiece 500 gradually decreases, the workpiece 500 becomes less likely to jump, the stability of the workpiece 500 gradually increases, and the grinding efficiency of the workpiece 500 also gradually improves.

[0038] In other embodiments, the plurality of grinding wheels 300 are divided into two equal parts along the direction from the first side to the second side of the frame 100. The grinding wheels 300 of one part, where the first connecting wheel 301 is located, perform rough grinding on the workpiece 500, and the last part, where the second connecting wheel 302 is located, performs fine grinding on the workpiece 500. The mesh number of the grinding wheel 300 for fine grinding is larger than that of the grinding wheel 300 for rough grinding.

[0039] The workpiece 500 first contacts the first connecting wheel 301 during the rough grinding phase. The first connecting wheel 301 grinds the workpiece 500 at a greater grinding depth and feed rate. During grinding, the ovality of the workpiece 500 is easier to improve than the roundness of the edges. Therefore, a higher center height H is used during rough grinding to improve roundness and prevent the workpiece 500 from getting stuck. During this phase, the ovality of the workpiece 500 changes minimally. The workpiece 500 then enters the fine grinding phase. At this stage, the center height H of the workpiece 500 is smaller than that used during rough grinding. This primarily improves ovality, while also further improving roundness and enhancing the accuracy of the workpiece 500.

[0040] In this embodiment, along the direction from the first side to the second side of the frame 100, the two sides of the third connecting wheel 303 are respectively the third side and the fourth side. Three first hinged rods 310 are respectively provided on the side of the second connecting wheel 302 close to the first side of the frame 100 and on the fourth side of each third connecting wheel 303. The three first hinged rods 310 are sequentially distributed along the circumference of the grinding wheel 300, and the first hinged rods 310 are arranged along the second direction. Three second hinged rods are respectively provided on the side of the first connecting wheel 301 close to the second side of the frame 100 and on the third side of each third connecting wheel 303. The three second hinged rods are sequentially distributed along the circumference of the grinding wheel 300, and the second hinged rods are arranged along the second direction.

[0041] Each connecting assembly includes a rotating frame 350, a first connecting unit and a second connecting unit. Three third hinge rods 320 are rotatably arranged on the rotating frame 350. The three third hinge rods 320 are sequentially distributed along the circumference of the rotating frame 350, and each third hinge rod 320 is arranged along the second direction.

[0042] The first connecting unit includes three first connecting rods 330. One end of each first connecting rod 330 is rotatably mounted on a third hinge rod 320 and is located on a side of the rotating frame 350 close to the fourth side of the grinding wheel 300. The other end of each first connecting rod 330 is rotatably mounted on a first hinge rod 310. The second connecting unit includes three second connecting rods 340. One end of each second connecting rod 340 is rotatably mounted on a third hinge rod 320 and is located on a side of the rotating frame 350 close to the third side of the grinding wheel 300. The other end of each second connecting rod 340 is rotatably mounted on a second hinge rod.

[0043] In this embodiment, the grinding mechanism further includes a plurality of connecting frames 360, which are sequentially arranged along the second direction. The connecting frames 360 are slidably mounted on the frame 100 along the second direction, with each grinding wheel 300 mounted on a connecting frame 360. Multiple support wheels 361 are rotatably mounted on each connecting frame 360, with the axes of the support wheels 361 arranged along the second direction. The support wheels 361 are sequentially arranged along the circumference of the grinding wheel 300, and the support wheels 361 abut against the grinding wheel 300, allowing the grinding wheel 300 to rotate freely on the connecting frames 360.

[0044] In this embodiment, the grinding mechanism also includes multiple cylinders 362, which are fixedly arranged on the frame 100. The cylinders 362 are arranged along the first direction. An elastic member is fixedly arranged on the extended end of each cylinder 362, and each elastic member is fixedly connected to a connecting frame 360.

[0045] When a workpiece 500 is about to become stuck, the elastic member is compressed, causing the connecting frame 360 ​​to move away from the workpiece 500, preventing the workpiece 500 from becoming stuck. The elastic member then allows the connecting frame 360 ​​to return to its original position. Furthermore, the multiple connecting assemblies allow the grinding wheels 300 to slide against each other without interfering with each other when grinding multiple workpieces 500, improving the applicability of the grinding wheels 300.

[0046] In this embodiment, a low-noise tapered roller bearing surface treatment device further includes a support mechanism, on which a plurality of workpieces 500 are sequentially distributed along a second direction. The support mechanism includes a first support frame and two second support frames 410. The first support frame and the second support frames 410 are both fixedly mounted on a frame 100. The two second support frames 410 are sequentially distributed along the second direction, with the first support frame disposed between the two second support frames 410. The first support frame includes a first support plate, the upper side of which is stepped, and the height of the stepped first support plate gradually decreases as it moves from the first side to the second side of the frame 100.

[0047] Each second support frame 410 includes a second support plate 411 and two limiting plates 412. The limiting plates 412 are arranged along the second direction. The two limiting plates 412 are sequentially distributed along the first direction. The second support plates 411 are arranged obliquely from the first side to the second side of the frame 100, and the second support plates 411 gradually approach the lower side of the frame 100. The second support plate 411 is located between the two limiting plates 412, and the workpiece 500 is located above the first support plate or the second support plate 411. The limiting plates 412 are used to limit the workpiece 500.

[0048] When the workpiece 500 moves from the second support plate 411 on the first side close to the frame 100 to the first support plate, the workpiece 500 comes into contact with the grinding wheel 300 .

[0049] Because the upper side of the first support plate is stepped, and the height of the stepped first support plate gradually decreases from the first side to the second side of the frame 100 to accommodate the workpiece 500 that is continuously moving downward. As the workpiece 500 moves from one grinding wheel 300 to the next, the workpiece 500 constantly abuts against the drive wheel 200. Therefore, as the workpiece 500 moves downward, it gradually moves downward along the circumference of the drive wheel 200. The drive wheel 200 acts as a buffer for the workpiece 500, helping to reduce the impact force of the workpiece 500 falling onto the stepped first support plate.

[0050] In this embodiment, the frame 100 includes a base frame 120 and a movable frame 130. The base frame 120 is disposed on the ground, and the connecting frame 360 ​​is disposed on the base frame 120. The movable frame 130 is slidably disposed on the base frame 120 along a first direction. The driving wheel 200 is rotatably disposed on the movable frame 130, and the support mechanism is fixedly disposed on the movable frame 130.

[0051] In this embodiment, the movable frame 130 includes a first movable plate 131 and a second movable plate 132. The first movable plate 131 is slidably disposed above the second movable plate 132 along a first direction. The support mechanism is fixedly disposed on the second movable plate 132. The driving wheel 200 is rotatably disposed on the first movable frame 130.

[0052] In this embodiment, a low-noise tapered roller bearing surface treatment device further includes a first hydraulic cylinder 140 and a second hydraulic cylinder. The first hydraulic cylinder 140 and the second hydraulic cylinder are both arranged along a first direction. The first hydraulic cylinder 140 is fixedly mounted on the second movable plate 132, and the extended end of the first hydraulic cylinder 140 is fixedly connected to the first movable plate 131. The second hydraulic cylinder is fixedly mounted on the base frame 120, and the extended end of the second hydraulic cylinder is fixedly connected to the second movable frame 130.

[0053] First, the second hydraulic cylinder is activated, which drives the second movable plate 132 and the first movable plate 131 to move synchronously, moving the support mechanism to the designated position. The first hydraulic cylinder 140 is then activated, causing the first movable plate 131 to move relative to the second movable plate 132. The first movable plate 131 drives the drive wheel 200 to move synchronously until the drive wheel 200 is moved to the designated position. This allows the workpiece 500 to be placed on the support mechanism, allowing it to contact the drive wheel 200 and the grinding wheel 300. Furthermore, the low-noise tapered roller bearing surface treatment device can grind workpieces 500 of varying diameters, offering greater applicability.

[0054] In this embodiment, the driving wheel mechanism further includes a second driving mechanism, which includes a second driving motor 150 . The second driving motor 150 is fixedly mounted on the movable frame 130 , and an output shaft of the second driving motor 150 is connected to the driving wheel 200 .

[0055] Working process: First, start the second hydraulic cylinder, which drives the second movable plate 132 and the first movable plate 131 to move synchronously, and move the support mechanism to the specified position. Then start the first hydraulic cylinder 140, so that the first movable plate 131 moves relative to the second movable plate 132, and the first movable plate 131 drives the driving wheel 200 to move synchronously until the driving wheel 200 is moved to the specified position.

[0056] Then, multiple workpieces 500 are placed on the second support frame 410 on the first side of the frame 100 . The two limiting plates 412 on the second support frame 410 abut against the workpieces 500 to prevent the workpieces 500 from separating from the second support frame 410 .

[0057] At this time, the grinding wheel 300 and the driving wheel 200 are both against the workpiece 500, and the workpiece 500 is continuously placed on the second support frame 410. Since the second support plate 411 is tilted and the workpiece 500 is continuously transported to the second support frame 410, the workpiece 500 moves on the support mechanism along the direction from the first side to the second side of the frame 100.

[0058] When the workpiece 500 moves from the second support plate 411 on the first side of the frame 100 to the first support plate, the workpiece 500 comes into contact with the grinding wheel 300. The first drive motor 110 and the second drive motor 150 are activated. The first drive motor 110 drives the second connecting wheel 302 to rotate in a forward direction, and through multiple connecting components, drives the multiple grinding wheels 300 to rotate synchronously. The second drive motor 150 drives the drive wheel 200 to rotate in a forward direction. The grinding wheels 300 and the drive wheels 200 rotate in the same direction. As the grinding wheels 300 and the drive wheels 200 rotate, they drive the workpiece 500 to rotate in the opposite direction, and the grinding wheels 300 begin to grind the workpiece 500.

[0059] The vertical distance between the center of the workpiece 500 and the line connecting the centers of the first connecting wheel 301 and the driving wheel 200 is set as the center height H. The workpiece 500 first abuts against the first connecting wheel 301. Since the linear distance between the first connecting wheel 301 and the driving wheel 200 is small, the center height H of the workpiece 500 is large.

[0060] Although the workpiece 500 has a large ovality, making it prone to bouncing, the workpiece 500 is less likely to become stuck because its center height is relatively high. When the first connecting wheel 301 grinds the workpiece 500, a large center height H makes it more likely that the workpiece 500 will bob on the grinding wheel 300. This reduces the ovality of the workpiece 500, but also reduces the grinding efficiency.

[0061] The workpiece 500 then moves onto the second connecting wheel 302 and moves downward. The center height H of the workpiece 500 on the second connecting wheel 302 is smaller than the center height H of the workpiece 500 on the first connecting wheel 301. As the center height H gradually decreases, the workpiece 500 becomes less likely to bounce, and the stability of the workpiece 500 gradually increases, thereby gradually improving the grinding efficiency of the workpiece 500.

[0062] However, as the center height H gradually decreases, the workpiece 500 can easily jam the grinding wheel 300, causing damage to the grinding wheel 300, the drive wheel 200, and the workpiece 500. By providing an elastic member, when the workpiece 500 shows signs of jamming, the elastic member is compressed, and the connecting frame 360 ​​moves away from the workpiece 500, helping to prevent jamming of the workpiece 500. Furthermore, by gradually reducing the center height of the workpiece 500, the workpiece 500 is gradually ground, preventing over-grinding.

[0063] By setting up multiple connecting components, multiple grinding wheels 300 can rotate simultaneously and move relative to each other, so that when the grinding mechanism is grinding multiple workpieces 500, multiple grinding wheels 300 can slide against each other without interfering with each other, thereby improving the applicability of the grinding wheels 300.

[0064] When the workpiece 500 moves from one grinding wheel 300 to the next grinding wheel 300, the workpiece 500 is always against the driving wheel 200. Therefore, when the workpiece 500 moves downward, the workpiece 500 gradually moves downward along the circumference of the driving wheel 200. The driving wheel 200 forms a buffer for the workpiece 500, which helps to reduce the impact force of the workpiece 500 falling on the stepped first support plate when moving downward.

[0065] The above description is only 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 in the scope of protection of the present invention.
