Description

Technical Field

[0001] This invention relates to the field of bearing processing technology, and in particular to a bearing grinding apparatus. Background Technology

[0002] Deep groove ball bearings, formerly known as radial ball bearings, are the most widely used type of rolling bearing. They are characterized by low frictional resistance and high speed. They can be used to bear radial loads or simultaneous radial and axial loads. They can also be used in machine parts that bear axial loads, such as small power electric motors, automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.

[0003] Currently, when machining and grinding the inner and outer rings of deep groove ball bearings, the clamping method for the inner and outer rings is singular, making it impossible to clamp the inner and outer rings simultaneously with a single machine. This results in the inability to conveniently grind the inner and outer rings of the bearing using a single grinding machine, thereby reducing grinding efficiency. Furthermore, grinding easily generates a large amount of dust, polluting the factory environment. Summary of the Invention

[0004] The purpose of this invention is to provide a bearing grinding device that solves the problem of the single clamping method for the inner and outer rings of deep groove ball bearings, which makes it impossible to grind the inner and outer rings with a single device and results in a large amount of dust during grinding.

When the plurality of fourth gears drive the plurality of racks to move, the plurality of first clamping members can move toward or away from each other to clamp or release the bearing outer ring.

[0009] In some more specific embodiments, the fixing plate is provided with a plurality of first sliding grooves distributed circumferentially along the internal gear ring, and each rack is provided with a first slider on one side, and one side of the first slider is slidably engaged inside the first sliding groove.

[0010] In some embodiments, the inner ring clamping assembly further includes: a fixed box, which is connected to the movable transmission assembly and has a mounting cavity for mounting the second driving member; a rotating disk, which is rotatably mounted on one end of the fixed box and connected to the driving end of the second driving member, and the rotating disk is provided with a plurality of second sliding grooves; wherein, the plurality of second clamping members are arranged in a circumferential array along the circumferential direction of the rotating disk, each of the second clamping members is provided with a second slider, and the plurality of second sliders are slidably engaged in the second sliding grooves in a one-to-one correspondence. When the second driving member drives the rotating disk to rotate, the plurality of second clamping members can move toward or away from each other to release or clamp the bearing inner ring.

[0011] In some specific embodiments, the inner ring clamping assembly further includes a fixing rod, which is installed at one end of the fixing box. Each fixing rod includes a fixing ring and multiple fixing branches. The fixing ring is sleeved on the driving end of the second driving member. Each fixing branch has a limiting groove at the end away from the fixing ring. Each second clamping member is slidably installed in the limiting groove at the end facing the fixing box.

[0012] In some specific embodiments, the moving transmission assembly includes: a screw, one end of which is connected to the side of the fixing plate opposite to the first clamping member, and the other end of which is rotatably mounted on the inner wall of the drive housing; a transmission belt assembly, which includes a driving pulley, a transmission belt, and a driven pulley, the driving pulley being mounted on the driving end of the first driving member, and the driven pulley being connected to the screw; and a fixing frame, which is threadedly connected to the screw and is used to mount the second driving member; wherein, when the first driving member drives the transmission belt assembly to move, the screw can rotate under the drive of the driven pulley to drive the fixing frame to move along the axial direction of the screw.

[0013] In some more specific embodiments, a limiting rod is fixedly installed at the end of the fixing plate away from the first clamping member, and the end of the limiting rod away from the fixing plate is spaced apart from the inner side wall of the drive housing, and the fixing frame is slidably engaged on the limiting rod.

[0014] In some embodiments, the bearing grinding device further includes a support housing for supporting the drive housing and the grinding housing. A liquid pump is fixedly installed on one side of the top of the support housing. The input end of the liquid pump is fixed to the bottom end of the support housing. A connecting pipe is installed at the output end of the liquid pump. The connecting pipe passes through the grinding housing, and at least one nozzle is provided on the side of the connecting pipe away from the liquid pump. The nozzle is used to spray grinding liquid toward the grinding body. A filter box and a filter cover are also slidably inserted into the support housing. The filter box is located below the nozzle, and the filter cover is installed below the filter box and is positioned corresponding to the input end of the liquid pump.

[0015] In some specific embodiments, a mesh conveyor belt is provided inside the grinding box. The mesh conveyor belt is arranged parallel to the drive box and passes through the grinding box. The top of the support box has a collection box corresponding to the end of the mesh conveyor belt that extends out of the grinding box.

[0016] The beneficial effects of this invention are as follows: In actual operation, by placing the bearing to be ground outside the second clamping member, multiple second clamping members move away from each other under the drive of the second driving member, thereby clamping the inner ring of the bearing. At this time, the grinding body can be started to grind the outer ring of the bearing. When the outer ring of the bearing is finished grinding, the second driving member drives multiple second clamping members to move closer to each other, thereby releasing the clamping of the inner ring of the bearing. Then, the first driving member is started, and multiple first clamping members can clamp the outer ring of the bearing under the drive of the first driving member. At the same time, the first driving member can also drive the moving transmission component to move, so that the second driving member moves away from the bearing until the second clamping members disengage from the inner ring of the bearing along the axial direction of the bearing. At this time, the grinding body can be started to grind the inner ring of the bearing. Thus, the bearing grinding device disclosed in this invention realizes the grinding of both the outer and inner rings of deep groove ball bearings, speeds up the work efficiency, and solves the defect of the prior art that the clamping method is single during grinding, resulting in the inability to grind both the inner and outer rings of deep groove ball bearings with a single device.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0031] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0033] The following is for reference. Figures 1-9The specific structure of the bearing grinding device according to an embodiment of the present invention is described.

[0034] This invention discloses a bearing grinding apparatus, with reference to Figure 1 and Figure 2 As shown, the bearing grinding device disclosed in this invention includes a drive housing 2 and a grinding housing 3. An outer ring clamping assembly 201 and an inner ring clamping assembly 202 are installed inside the drive housing 2. The outer ring clamping assembly 201 includes a first driving member 21 and a plurality of first clamping members 26. The plurality of first clamping members 26 can clamp the outer ring of the bearing under the drive of the first driving member 21. The inner ring clamping assembly 202 includes a second driving member 281, a plurality of second clamping members 27, and a moving transmission assembly. The plurality of second clamping members 27 are driven by the second driving member 281 and can clamp the bearing inner ring under the drive of the second driving member 281. The moving transmission assembly is driven by the first driving member 21 and connected to the second driving member 281. The grinding box 3 is arranged in parallel and connected with the drive box 2. The grinding box 3 is equipped with a grinding body 32, which is used to grind the bearing outer ring and the bearing inner ring. When the first driving member 21 drives the first clamping member 26 to clamp the bearing outer ring, the moving transmission assembly can drive the second clamping member 27 to move away from the grinding body 32.

[0035] Understandably, in actual operation, by placing the bearing to be ground outside the second clamping member 27, multiple second clamping members 27 move away from each other under the drive of the second drive member 281, thereby clamping the inner ring of the bearing. At this time, the grinding body 32 can be activated to grind the outer ring of the bearing. When the outer ring of the bearing is finished being ground, the second drive member 281 drives multiple second clamping members 27 to move closer to each other, thereby releasing the clamping of the inner ring of the bearing. Then, the first drive member 21 is activated, and multiple first clamping members 26 can clamp the outer ring of the bearing under the drive of the first drive member 21. At the same time, the first drive member 21 can also drive the moving transmission component to move, so that the second drive member 281 moves away from the bearing until the second clamping members 27 disengage from the inner ring of the bearing along the axial direction of the bearing. At this time, the grinding body 32 can be activated to grind the inner ring of the bearing. Therefore, the bearing grinding device disclosed in this invention realizes the grinding of the outer ring and inner ring of deep groove ball bearings, speeds up the work efficiency, and solves the defect of the prior art that the clamping method is single during grinding, which makes it impossible to grind the inner and outer rings of deep groove ball bearings with one device.

[0036] refer to Figure 3As shown, the bearing grinding device also includes a support housing 1, which supports the drive housing 2 and the grinding chamber 3. A liquid pump 12 is fixedly installed on one side of the top of the support housing 1. The input end of the liquid pump 12 is fixed to the bottom end of the support housing 1, and a connecting pipe 13 is installed on the output end of the liquid pump 12. The connecting pipe 13 passes through the grinding chamber 3, and at least one nozzle 14 is provided on the side of the connecting pipe 13 away from the liquid pump 12. The nozzle 14 is used to spray grinding fluid toward the grinding body 32. It can be understood that in actual operation, the lower end of the support housing 1 contains grinding fluid (which can be water or other liquids). The liquid pump 12 can draw out the grinding fluid and send it to the nozzle 14. The nozzle 14 can spray the grinding fluid toward the grinding body 32, which on the one hand settles the dust generated during grinding, and on the other hand cools down the heat generated during grinding, thereby improving the grinding quality.

[0037] Optionally, there are two nozzles 14, arranged symmetrically. This improves the uniformity of the grinding fluid spray, thereby aiding in dust reduction and cooling. Of course, in other embodiments of the present invention, the number of nozzles 14 can be adjusted according to actual needs, and is not limited to the two in this embodiment.

[0038] Optionally, the support housing 1 also slidably houses a filter box 11 and a filter cover 121. The filter box 11 is located below the nozzle 14, and the filter cover 121 is installed below the filter box 11 and is positioned corresponding to the input end of the pump 12. It is understood that when the grinding fluid falls under gravity, it passes through the filter box 11, and larger dust particles remain on the filter box 11. The filter cover 121, positioned corresponding to the input end of the pump 12, filters the liquid entering the pump 12. By setting up the filter box 11 and the filter cover 121, dust and other impurities can be prevented from entering the pump 12 and causing damage to it.

[0039] Alternatively, a handle 111 is fixedly installed on the middle of one side of the filter box 11, passing through the support box 1. This allows the filter box 11 to be easily pulled out from one side of the support box 1 for cleaning.

[0040] refer to Figure 3As shown, a mesh conveyor belt 16 is installed inside the grinding chamber 3. The mesh conveyor belt 16 is parallel to and passes through the grinding chamber 3, and the top of the support chamber 1 has a collection box 15 corresponding to the mesh conveyor belt 16 extending out of the grinding chamber 3. It can be understood that after grinding is completed, the first drive member 21 rotates in the opposite direction to release the clamping of the bearing. At the same time, the second clamping member 27 extends through the telescopic port 241 to push the bearing, causing it to fall onto the upper part of the mesh conveyor belt 16. The mesh conveyor belt 16 is driven by an external servo drive member to move the bearing out of the grinding chamber 3, so that the ground bearing falls into the collection box 15. The added collection box 15 facilitates the collection of the ground bearing after it is conveyed out of the grinding chamber 3 by the mesh conveyor belt 16, thus making it convenient for workers to handle. The use of a mesh conveyor belt 16 facilitates stable transport of the bearings, and the grinding fluid sprayed from the nozzle 14 can fall from the mesh conveyor belt 16 into the support box 1, ensuring that the grinding fluid can be recycled.

[0041] refer to Figure 4 and Figure 5 As shown, the outer ring clamping assembly 201 also includes an outer ring transmission assembly. The power input end of the outer ring transmission assembly is in transmission cooperation with the first driving member 21. The outer ring transmission assembly has multiple power output ends, which correspond one-to-one with multiple first clamping members 26. It can be understood that in actual operation, the outer ring transmission assembly enables one first driving member 21 to drive multiple first clamping members 26, which simplifies the structure of the outer ring clamping assembly 201, facilitates its assembly, and reduces its manufacturing cost.

[0042] refer to Figure 4 and Figure 5 As shown, the drive housing 2 also includes a fixed plate 24. Multiple first clamping members 26 and an outer ring transmission assembly are mounted on one side of the fixed plate 24, while a movable transmission assembly is mounted on the other side. The fixed plate 24 has a telescopic opening 241, through which multiple second clamping members 27 can pass under the influence of the movable transmission assembly. It is understood that by setting the fixed plate 24 to install the first clamping members 26, the outer ring transmission assembly, and the movable transmission assembly on opposite sides, the structural compactness is improved, thereby enhancing the space utilization within the drive housing 2. Simultaneously, the telescopic opening 241 on the fixed plate 24 allows the multiple second clamping members 27 to move to the side of the fixed plate 24 away from the grinding body 32 under the influence of the movable transmission assembly when the grinding body 32 grinds the bearing inner ring. This ensures that the second clamping members 27 do not interfere with the grinding of the bearing inner ring, thus improving the grinding effect.

[0043] Optional, see reference Figure 4 and Figure 5 As shown, the outer ring transmission assembly includes a first gear 211, a second gear 22, a third gear 23, and a plurality of fourth gears 25. The first gear 211 is mounted on the output shaft of the first drive member 21. The second gear 22 meshes with the first gear 211. The third gear 23 is an internal gear ring. The third gear 23 is connected to the radial interior of the second gear 22 and is connected to the fixed plate 24. The plurality of fourth gears 25 are distributed at intervals along the circumference of the internal gear ring and mesh with the internal gear ring respectively. Each first clamping member 26 is equipped with a rack 263, and multiple racks 263 mesh with multiple fourth gears 25 in a one-to-one correspondence. Understandably, during actual operation, after the first driving member 21 is activated, its output shaft drives the first gear 211 to rotate. Since the first gear 211 meshes with the second gear 22, and the third gear 23 is connected radially inside the second gear 22, the rotation of the first gear 211 drives the second gear 22 and the third gear 23 to rotate. Because the multiple fourth gears 25 are circumferentially spaced along the inner gear ring, when the third gear 23 rotates, the multiple fourth gears 25 can rotate on their own, thereby driving the multiple racks 263 to move. During the movement of the multiple racks 263, the multiple first clamping members 26 can move towards or away from each other to clamp or release the bearing outer ring.

[0044] In summary, this embodiment utilizes a planetary gear structure composed of a first gear 211, a second gear 22, a third gear 23, and multiple fourth gears 25 to ensure the simultaneous movement of multiple first clamping members 26, thereby ensuring stable clamping of the bearing outer ring. Optionally, in this embodiment, there are four fourth gears 25 and four first clamping members 26. This further ensures stable clamping of the bearing outer ring. Of course, in other embodiments of the invention, the number of first clamping members 26 can be adjusted according to actual needs; it can be three, five, or other numbers.

[0045] Further optional, see reference Figure 5 and Figure 7As shown, the fixed plate 24 is provided with a plurality of first sliding grooves 262 spaced circumferentially along the internal gear ring. Each rack 263 has a first slider 261 on one side, and one side of the first slider 261 is slidably engaged inside the first sliding groove 262. It can be understood that by setting the first slider 261 and the first sliding groove 262, when the plurality of fourth gears 25 rotate to drive the plurality of racks 263 to move, the limiting effect of the first sliding groove 262 on the first slider 261 can limit and guide the movement of the racks 263, thereby avoiding the phenomenon that the racks 263 are skewed and the plurality of first clamping members 26 are jammed during actual operation. Of course, in other embodiments of the present invention, the first slider 261 can also be set on the fixed plate 24, and the first sliding groove 262 can be set on the rack 263.

[0046] refer to Figure 6 As shown, the moving transmission assembly includes a screw 29, a transmission belt assembly 291, and a fixing frame 292. One end of the screw 29 is connected to the side of the fixing plate 24 away from the first clamping member 26, and the other end of the screw 29 is rotatably mounted on the inner wall of the drive housing 2. The transmission belt assembly 291 includes a driving pulley, a transmission belt, and a driven pulley. The driving pulley is mounted on the driving end of the first driving member 21, and the driven pulley is connected to the screw 29. The fixing frame 292 is threadedly connected to the screw 29, and the fixing frame 292 is used to mount the second driving member 281. When the first driving member 21 drives the transmission belt assembly 291 to move, the screw 29 can rotate under the drive of the driven pulley to drive the fixing frame 292 to move along the axial direction of the screw 29. Understandably, when the first drive member 21 drives multiple first clamping members 26 to clamp the outer ring of the bearing, the drive pulley of the transmission belt assembly 291 can also rotate, causing the driven pulley to rotate under the drive of the transmission belt. Since the driven pulley is connected to the screw 29, the rotation of the driven pulley will drive the screw 29 to rotate. The rotation of the screw 29 will drive the fixing frame 292 to move along the axial direction of the screw 29, thereby allowing the second drive member 281 and the second clamping member 27 to pass through the telescopic opening 241 and enter the side of the fixing plate 24 away from the grinding body 32. By driving the second drive member 281 and the second clamping member 27 to move by the screw 29, it can be ensured that the second drive member 281 and the second clamping member 27 move stably within the telescopic opening 241, avoiding the phenomenon of the second drive member 281 and the second clamping member 27 being collided.

[0047] Optionally, a limiting rod 293 is fixedly installed at the end of the fixing plate 24 away from the first clamping member 26. The end of the limiting rod 293 away from the fixing plate 24 is spaced apart from the inner side wall of the drive housing 2, and the fixing frame 292 is slidably engaged with the limiting rod 293. It can be understood that since the fixing frame 292 is slidably engaged with the limiting rod 293, when the fixing frame 292 moves under the drive of the screw 29, the limiting rod 293 can play a good limiting and guiding role, thereby avoiding the phenomenon of the second driving member 281 and the second clamping member 27 being collided due to the tilt of the fixing frame 292.

[0048] refer to Figure 8 and Figure 9 As shown, the inner ring clamping assembly 202 also includes a fixed box 28 and a rotating disk 271. The fixed box 28 is connected to the moving transmission assembly and has a mounting cavity for mounting the second driving member 281. The rotating disk 271 is rotatably mounted on one end of the fixed box 28 and connected to the driving end of the second driving member 281. The rotating disk 271 is provided with a plurality of second sliding grooves 273. A plurality of second clamping members 27 are arranged in a circumferential array along the circumferential direction of the rotating disk 271. Each second clamping member 27 is provided with a second slider 272, and the plurality of second sliders 272 are slidably engaged in the second sliding grooves 273 one-to-one. Understandably, during actual operation, after the second driving component 281 is activated, it drives the rotating disk 271 to rotate. As the rotating disk 271 rotates, the sidewall of the second sliding groove 273 pushes the second slider 272 to move, thereby enabling the multiple second clamping components 27 to move towards or away from each other. That is, the outer diameter of the ring formed by the multiple second clamping components 27 decreases or increases, thus releasing or clamping the bearing inner ring. By driving the multiple arc-shaped second clamping components 27 through the rotating disk 271 to clamp the bearing inner ring, it ensures stable clamping of the bearing inner ring and reduces the possibility of damage, thus protecting the bearing inner ring. Installing the second driving component 281 in the fixed box 28 provides protection for the second driving component 281. Optionally, in this embodiment, the number of second clamping components 27 is four, thereby stably and effectively clamping the bearing inner ring. Of course, in other embodiments of the present invention, the number of second clamping components 27 can be three, five, or other numbers.

[0049] Optional, see reference Figure 6As shown, the inner ring clamping assembly 202 also includes a fixing rod 282, which is installed at one end of the fixing box 28. Each fixing rod 282 includes a fixing ring and multiple fixing branches. The fixing ring is sleeved on the driving end of the second driving member 281. Each fixing branch has a limiting groove 283 at the end away from the fixing ring. Each second clamping member 27 is slidably installed in the limiting groove 283 at the end facing the fixing box 28. It can be understood that by setting the fixing rod 282, the limiting groove 283 can restrict the sliding direction of the second clamping members 27 during rotation, ensuring that the outer surface splicing of the multiple second clamping members 27 is always a perfect circle, thereby ensuring stable clamping of the bearing inner ring and reducing the possibility of damage to the bearing inner ring, which is beneficial to protecting the bearing inner ring.

[0050] The working principle of the bearing grinding device in this embodiment is as follows:

[0051] By placing the bearing to be ground on the outer wall of the second clamping member 27, the rotating disk 271 is driven to rotate by the second driving member 281. Since the second slider 272 is slidably locked inside the second slide groove 273, the second clamping member 27, which is fixedly installed on one side of the second slider 272, expands, thereby clamping and fixing the inner ring of the bearing. At this time, the grinding body 32 can be started to grind the outer ring of the bearing.

[0052] After the outer ring of the bearing is ground, the inner ring of the bearing can be released by rotating the second drive member 281 in the reverse direction. Activating the first drive member 21 drives the first gear 211 to rotate, which in turn drives the second gear 22, the third gear 23, and the fourth gear 25, causing the rack 263 to move. This, in turn, moves the first clamping member 26 inward, thus clamping and fixing the outer ring of the bearing. Simultaneously, the drive belt assembly 291 causes the screw 29 to rotate, moving the fixing bracket 292 mounted on the outer surface of the screw 29. This moves the fixing box 28, allowing the second clamping member 27 to enter the other side of the fixing plate 24 through the telescopic opening 241. At this time, the grinding body 32 is started, and the inner ring of the bearing can be ground. After the grinding is completed, the first drive member 21 rotates in the opposite direction to release the clamp on the bearing. At the same time, the second clamping member 27 extends through the telescopic port 241 to push the bearing and make it fall onto the upper part of the mesh conveyor belt 16. The mesh conveyor belt 16 is driven by the servo drive member to move the bearing to the outside of the grinding box 3, so that the ground bearing falls into the inside of the collection box 15.

[0053] It should be noted that after the bearing is placed on the second clamping member 27, the baffle 31 can be pushed to one side to seal the grinding box 3. The liquid inside the support box 1 is extracted by starting the liquid pump 12. After being transmitted through the connecting pipe 13, the liquid flows out from the nozzle 14 to settle the dust generated during grinding and cool down the heat generated during grinding. After the dust is settled, the liquid is filtered through the filter box 11 and flows back to the lower part of the support box 1 for continued use. The filter box 11 can be pulled out by pulling the handle 111 for cleaning.
