Description

Technical Field

[0001] This invention relates to the field of bearings, and more particularly to a bearing ring polishing device. Background Technology

[0002] Bearing ring polishing is a key surface finishing process designed to improve the surface quality of the raceway and end face of the ring. Through mechanical friction and micro-cutting, it effectively removes micro-burrs, tool marks, and altered layers remaining after turning and grinding of the ring, significantly reducing surface roughness.

[0003] In existing technologies, the ferrule is usually precisely clamped and rotated during operation. Tools such as high-speed driven fiber polishing wheels, sanding belts, or polishing wheels coated with polishing paste are used to grind a specific surface with constant pressure. During the polishing process, it is necessary to adjust the intensity and fineness of the abrasive particles to adapt to different degrees of polishing. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bearing ring polishing device.

[0005] This invention provides a bearing ring polishing device, including a housing, and further comprising:

[0006] A bracket is fixed to the top of the housing;

[0007] A cylinder is fixed to the top of the bracket;

[0008] A horizontal plate is fixed to the end of the telescopic rod of the cylinder;

[0009] A pivot is rotatably mounted on the bottom of the horizontal plate, and its bottom extends through the housing and into the interior of the housing;

[0010] The first motor is mounted on the top of the bracket via a mounting bracket, and the first motor drives the rotating shaft to rotate;

[0011] A collection trough is fixed to the bottom of the housing, and a through groove is left between the collection trough and the housing for the bearing rings to be loaded and unloaded.

[0012] A positioning switching component is installed between the housing and the rotating shaft to switch between inner ring fixing and outer ring fixing of the bearing race, so as to achieve external and internal polishing of the bearing race;

[0013] The liquid inlet assembly is installed between the collection tank and the positioning switching assembly, and is used to cooperate with the positioning switching assembly to adjust the liquid inlet of the chemical mechanical polishing slurry to promote polishing;

[0014] The worker places the bearing race to be polished in the designated position, then activates the cylinder. The cylinder moves the horizontal plate downwards, which in turn moves the rotating shaft downwards. This causes the rotating shaft to move the positioning switching component downwards, positioning it to the center of the bearing race. The bearing race is then positioned, starting with the inner ring. Next, the first motor is started. Once started, the first motor directly drives the rotating shaft via its output shaft, or via a drive gear, causing the rotating shaft to rotate. This rotating shaft then drives the positioning switching component, which in turn rotates the bearing race. After the bearing ring rotates, it cooperates with the positioning switching component to polish the outer surface of the bearing ring. During the polishing process, the liquid inlet component delivers chemical mechanical polishing fluid to the polishing position to assist the polishing process. Then, the first motor stops, and the positioning switching component is started to switch and fix the outer wall of the bearing ring. When the first motor restarts, it drives the rotating shaft to rotate again. The rotation of the rotating shaft drives the positioning switching component to rotate and polish the inner wall of the bearing ring. This realizes the automatic switching polishing of the inner and outer side walls of the bearing ring, thereby improving the processing efficiency of the bearing ring.

[0015] Preferably, the positioning switching component includes:

[0016] Two sets of boxes, two boxes forming a group, the boxes in the same group are set at the same horizontal level and are respectively fixed to the inner wall of the shell and the outer wall of the rotating shaft;

[0017] Four sets of sliding tables, with several sets of sliding tables forming a group. A group of sliding tables is arranged in a circular array and slidably inserted inside the box. The opposing surfaces of the two sets of sliding tables corresponding to the box in the same group penetrate the box.

[0018] Four sets of rotating plates are respectively rotatably installed inside the four boxes;

[0019] Four sets of guide grooves, with multiple guide grooves forming a group, and the four sets of guide grooves are respectively arranged in a circular array and pass through the four sets of guide grooves;

[0020] Several sliders are fixed on each of the slide platforms and slidably connected to each of the guide grooves;

[0021] Four annular teeth are respectively opened on the four sets of rotating plates;

[0022] Four second motors are respectively fixed on the four housings, and each output shaft is fixed with a gear, which meshes with the ring gear;

[0023] After the second motor starts, it drives the gear to rotate through the output shaft. The gear rotates and drives the ring tooth that meshes with it to rotate. The ring tooth drives the rotating plate to rotate. The rotating plate drives the guide groove to rotate. The guide groove guides and pushes the slider to move under the action of the slider. In turn, the slider drives the slide table to move. After the slide table moves, it forms a clamp.

[0024] Specifically, the two sets of slides at the top have an inner ring slide for polishing and an outer ring slide for clamping and fixing. Similarly, the two sets of slides at the bottom have an inner ring slide for clamping and fixing and an outer ring slide for polishing. Thus, the inner ring is polished by clamping the slides on the outer ring at the top, and the outer ring is polished by clamping the slides on the inner ring at the bottom. The vertical movement of the two sets of slides on the inner ring allows for switching between clamping positions, facilitating automatic switching of polishing operations.

[0025] Preferably, the positioning switching component further includes:

[0026] A conical guide platform is fixed to the bottom of the rotating shaft;

[0027] As the shaft moves downward, it drives the tapered guide platform downward. The tapered guide platform moves downward and enters the middle of the bearing ring, pushing the bearing ring against the shaft. This facilitates the clamping of the bearing ring and prevents it from falling off due to poor positioning.

[0028] Preferably, the liquid inlet assembly includes:

[0029] Two liquid tanks are symmetrically fixed on both sides of the collection tank;

[0030] An inner groove is formed inside the rotating shaft and connects to the inner ring of the housing in a set of housings;

[0031] Two connecting pipes are provided. One connecting pipe connects the liquid tank to the outer ring of another set of tanks. The other connecting pipe rotatably connects to the inner groove. A delivery pump is connected to the middle of each connecting pipe. A liquid inlet groove is opened at the bottom of the side wall of the end of the connecting pipe that connects to the liquid tank.

[0032] The delivery pump connected by the connecting pipe can drive the flow of chemical mechanical polishing fluid inside the liquid tank, so that the chemical mechanical polishing fluid flows upward along the connecting pipe to the inside of the inner tank, which is the inner tank of the corresponding polishing slide. Then, the chemical mechanical polishing fluid enters the polishing position along the polishing slide, thereby improving the polishing efficiency of the bearing ring.

[0033] Preferably, the liquid inlet assembly further includes:

[0034] A plurality of flexible polishing heads, the flexible polishing heads being elastic and porous, the flexible polishing heads being respectively fixed to all the slide ends on the inner ring of the housing in one group and all the slide ends on the outer ring of the housing in another group, so as to polish the bearing rings towards the bearing rings;

[0035] The flexible polishing head is fixed to the end of the polishing slide and is usually a polyurethane pad. It has a certain degree of elasticity and porosity, which can both conform to the shape of the curved surface and store and transport polishing fluid.

[0036] Preferably, the liquid inlet assembly further includes:

[0037] Two recycling troughs are fixed to the bottom of the two boxes located on the outer ring, and both recycling troughs are connected to the collection trough through recycling pipes, and a negative pressure pump is provided to connect to the recycling pipes to assist recycling.

[0038] During the polishing process, due to the high-speed rotation of the bearing rings, the chemical mechanical polishing slurry added during the polishing process and the particles formed during polishing are thrown outward under the action of centripetal force. The thrown chemical mechanical polishing slurry and particles enter the interior of the recycling tank, and then enter the interior of the collection tank along the recycling pipeline under the action of the negative pressure pump to achieve recycling. The collection tank can be connected to the external large recycling box to recycle the generated waste liquid for centralized treatment or reuse.

[0039] Preferably, the liquid inlet assembly further includes:

[0040] Two sealing plugs are slidably installed on the top of the two liquid tanks, respectively;

[0041] Two sets of frames, with multiple frames forming a group, and the frames in the same group connected sequentially by ropes, are slidably installed in the interior of the two liquid tanks in a vertical linear array. Each frame has a multi-stage filter screen fixed at its center, and the mesh size of the multi-stage filter screens corresponding to the frames in the same group gradually increases from top to bottom.

[0042] An external pump delivers chemical mechanical polishing (CMP) slurry from the external reservoir into the liquid tank. The pump's output is located between the sealing plug and the top frame. Once inside the liquid tank, the CMP slurry is filtered through a multi-stage filter to create a multi-stage slurry containing varying particle sizes. The connecting pipe, positioned between the sealing plug and the top frame, moves with the sealing plug, initially delivering the top layer of slurry with the largest particles. As the slurry is delivered, the distance between the sealing plug and the top frame decreases, allowing the connecting pipe to move between the bottom frame and the next frame to deliver the second stage of slurry. This automatic change of slurry facilitates more precise polishing of bearing rings, improving polishing efficiency.

[0043] Preferably, the liquid inlet assembly further includes:

[0044] Multiple sets of built-in electromagnet plates, with multiple built-in electromagnet plates forming a group, and the built-in electromagnet plates in the same group arranged in a linear array, and the built-in electromagnet plates in the same group fixed to the bottom of the same frame;

[0045] Multiple sets of built-in magnet plates, with multiple built-in magnet plates forming a group, the built-in magnet plates in the same group arranged in a linear array and fixed to the bottom of the same frame, the gap between the built-in magnet plates and their adjacent built-in electromagnet plates;

[0046] The built-in electromagnet plate and the built-in magnet plate can move closer and further apart under the action of the electromagnet. This allows the built-in electromagnet plate and the built-in magnet plate to be kept away from the exposed space when the polishing liquid is fed into the liquid tank, which facilitates liquid feeding and multi-stage filtration. When the polishing liquid is discharged from the liquid tank, the built-in electromagnet plate and the built-in magnet plate are brought into contact with each other. Under the negative pressure during the discharge, the sealing plug can be moved downward, which in turn pushes the frame downward, thereby automatically realizing the switching of multi-stage polishing liquid.

[0047] Preferably, the liquid inlet assembly further includes:

[0048] The bottom ends of the built-in electromagnet plate and the top ends of the built-in magnet plate are both set as inclined surfaces, and the inclined surfaces are adapted to fit each other. A corrosion-resistant rubber layer is fixed on each of the inclined surfaces.

[0049] The beveled design increases the contact area between the built-in electromagnet plate and the built-in magnet plate, and the anti-corrosion rubber layer improves the sealing effect.

[0050] Preferably, the multi-stage filter screen includes:

[0051] The frame is fixed to the top of the multi-stage filter screen;

[0052] A ring frame is fixed at the center of the multi-stage filter screen and surrounds the connecting pipe;

[0053] The frame design improves support when the multi-stage filter moves under negative pressure, while the ring frame allows the multi-stage filter to slide along the connecting pipe, thus improving the sealing effect.

[0054] Compared with the prior art, the present invention has the following beneficial effects:

[0055] The rotation of the shaft drives the positioning switching component to polish the inner wall of the bearing ring, thereby achieving automatic switching polishing of the inner and outer side walls of the bearing ring and improving the processing efficiency of the bearing ring.

[0065] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0066] like Figures 1 to 8 The bearing ring polishing device shown includes a housing 1, and further includes:

[0067] The bracket 101 is fixed to the top of the housing 1;

[0068] Cylinder 102 is fixed to the top of bracket 101;

[0069] A horizontal plate 103 is fixed to the end of the telescopic rod of the cylinder 102;

[0070] The rotating shaft 104 is rotatably mounted on the bottom of the horizontal plate 103, and extends through the housing 1 and into the interior of the housing 1.

[0071] The first motor 105 is mounted on the top of the bracket 101 via a mounting bracket, and the first motor 105 drives the rotating shaft 104 to rotate.

[0072] The collecting trough 106 is fixed to the bottom of the housing 1, and a through groove is left between it and the housing 1 for the bearing rings to be loaded and unloaded.

[0073] The positioning switching component is installed between the housing 1 and the rotating shaft 104 to switch between inner ring fixing and outer ring fixing of the bearing race, so as to achieve external and internal polishing of the bearing race.

[0074] The liquid inlet assembly is installed between the collection tank 106 and the positioning switching assembly. It is used to cooperate with the positioning switching assembly to adjust the liquid inlet of the chemical mechanical polishing slurry to promote polishing.

[0075] In existing technology, the ferrule is usually precisely clamped and rotated during operation. Tools such as high-speed driven fiber polishing wheels, sanding belts, or polishing wheels coated with polishing paste are used to grind a specific surface with constant pressure. During the polishing process, it is necessary to adjust the intensity and fineness of the abrasive particles to adapt to different degrees of polishing.

[0076] This embodiment of the invention can solve the above problems. The specific implementation is as follows: The worker places the bearing ring to be polished in the designated position, then starts the cylinder 102. The cylinder 102 drives the horizontal plate 103 downwards, which in turn drives the rotating shaft 104 downwards. This causes the rotating shaft 104 to move the positioning switching component downwards, moving it to the center of the bearing ring. The bearing ring is then positioned, first by positioning the inner ring. Then, the first motor 105 is started. After starting, the first motor 105 directly drives the rotating shaft 104 to rotate via its output shaft, or drives the rotating shaft 104 to rotate via a drive gear. 04 drives the positioning switching component to rotate, thereby driving the bearing ring to rotate. After the bearing ring rotates, it cooperates with the positioning switching component to polish the outer surface of the bearing ring. During the polishing process, the liquid inlet component delivers chemical mechanical polishing fluid to the polishing position to assist the polishing process. Then, the first motor 105 stops, and then the positioning switching component is started to switch, so that the outer wall of the bearing ring is positioned and fixed. When the first motor 105 restarts, it drives the rotating shaft 104 to rotate again. The rotation of the rotating shaft 104 drives the positioning switching component to rotate and polish the inner wall of the bearing ring, thereby realizing the automatic switching polishing of the inner ring side wall and the outer ring side wall of the bearing ring, thereby improving the processing efficiency of the bearing ring.

[0077] As an optional embodiment, the positioning switching component includes:

[0078] Two sets of boxes 2, two boxes 2 form a group, and the boxes 2 in the same group are set at the same horizontal level and are respectively fixed to the inner wall of the shell 1 and the outer wall of the rotating shaft 104;

[0079] Four sets of slides 201, with a number of slides 201 forming a group. A group of slides 201 is arranged in a circular array and slidably inserted inside the box 2. The opposing surfaces of the two sets of slides 201 corresponding to the box 2 in the same group penetrate the box 2.

[0080] Four sets of rotating plates 202 are respectively rotatably installed inside the four boxes 2;

[0081] Four sets of guide grooves 203, multiple guide grooves 203 are grouped together, and the four sets of guide grooves 203 are respectively arranged in a circular array and are opened through the four sets of guide grooves 203;

[0082] Several sliders 204 are fixed on each slide table 201 and are slidably connected to each guide groove 203.

[0083] Four annular teeth 207 are respectively opened on four sets of rotating plates 202;

[0084] Four second motors 206 are fixed on four housings 2 respectively, and each output shaft is fixed with a gear 205, which meshes with a ring gear 207;

[0085] After the second motor 206 starts, it drives the gear 205 to rotate through the output shaft. The gear 205 rotates and drives the ring gear 207 that meshes with it to rotate. The ring gear 207 drives the rotating plate 202 to rotate. The rotating plate 202 drives the guide groove 203 to rotate. The guide groove 203 guides and pushes the slider 204 to move under the cooperation of the slider 204. Thus, the slider 204 drives the slide table 201 to move. After the slide table 201 moves, it forms a clamp.

[0086] Specifically, in the two sets of upper slides 201, the inner slide 201 is a polishing slide, and the outer slide 201 is a clamping and fixing slide. In the two sets of lower slides 201, the inner slide 201 is a clamping and fixing slide, and the outer slide 201 is a polishing slide. Thus, the inner ring is polished by clamping the outer ring from above, and the outer ring is polished by clamping the inner ring from below. The clamping can be switched by the vertical movement of the two sets of inner slides 201, which facilitates automatic switching of polishing.

[0087] As an optional embodiment, the positioning switching component further includes:

[0088] The conical guide platform 3 is fixed to the bottom of the rotating shaft 104;

[0089] When the rotating shaft 104 moves downward, it drives the conical guide platform 3 to move downward. The conical guide platform 3 moves downward and enters the middle of the bearing ring to push the bearing ring against the rotating shaft 104, thereby facilitating the clamping of the bearing ring and preventing it from falling off due to poor positioning.

[0090] As an optional embodiment, the liquid inlet assembly includes:

[0091] Two liquid tanks 5 are symmetrically fixed on both sides of the collection tank 106;

[0092] The inner groove 502 is opened inside the rotating shaft 104 and is connected to the inner ring of the box 2 in a set of boxes 2;

[0093] Two connecting pipes 501, one connecting pipe 501 connects the liquid tank 5 to the outer ring of the other set of tanks 2, and the other connecting pipe 501 rotatably connects to the inner groove 502. The middle part of each connecting pipe 501 is connected to a delivery pump, and the bottom of the side wall of the end of the connecting pipe 501 connected to the liquid tank 5 is provided with a liquid inlet groove.

[0094] The delivery pump connected to the connecting pipe 501 can drive the chemical mechanical polishing slurry inside the liquid tank 5 to flow, so that the chemical mechanical polishing slurry flows upward along the connecting pipe 501 to the inside of the inner groove 502, which is the inner groove 502 of the corresponding polishing slide. Then, the chemical mechanical polishing slurry enters the polishing position along the polishing slide, thereby improving the polishing efficiency of the bearing ring.

[0095] As an optional embodiment, the liquid inlet assembly further includes:

[0096] Several flexible polishing heads, which are elastic and porous, are respectively fixed to the ends of all slides 201 on the inner ring of the housing 2 in one group and the ends of all slides 201 on the outer ring of the housing 2 in another group, so as to polish the bearing rings.

[0097] The flexible polishing head is fixed to the end of the polishing slide and is usually a polyurethane pad. It has a certain degree of elasticity and porosity, which can both conform to the shape of the curved surface and store and transport polishing fluid.

[0098] As an optional embodiment, the liquid inlet assembly further includes:

[0099] Two recycling tanks 4 are fixed to the bottom of two boxes 2 located on the outer ring, and both recycling tanks 4 are connected to the collection tank 106 through recycling pipes, and a negative pressure pump is provided to connect to the recycling pipes to assist recycling.

[0100] During the polishing process, due to the high-speed rotation of the bearing rings, the chemical mechanical polishing slurry added during the polishing process and the particles formed by polishing are thrown outward under the action of centripetal force. The thrown chemical mechanical polishing slurry and particles enter the interior of the recovery tank 4, and then enter the interior of the collection tank 106 through the recovery pipeline under the action of the negative pressure pump for recycling. The collection tank 106 can be connected to the external large recovery box to recover the generated waste liquid for centralized treatment or reuse.

[0101] As an optional embodiment, the liquid inlet assembly further includes:

[0102] Two sealing plugs 6 are slidably installed on the top of the two liquid tanks 5 respectively;

[0103] Two sets of frames 601, multiple frames 601 are grouped together, and the frames 601 in the same group are connected in sequence by ropes. They are slidably installed in the interior of two liquid tanks 5 in a vertical linear array. Each frame 601 has a multi-stage filter screen 602 fixed at its center. The multi-stage filter screen 602 corresponding to the frame 601 in the same group has a gradually increasing filter mesh size from top to bottom.

[0104] An external pump delivers chemical mechanical polishing (CMP) slurry from the external storage tank to the liquid tank 5. The pump's output is located between the sealing plug 6 and the top frame 601. Once inside the liquid tank 5, the CMP slurry is filtered through a multi-stage filter 602, resulting in a multi-stage polishing slurry containing particles of varying fineness. The slurry is then transported via a connecting pipe 501, the end of which is positioned between the sealing plug 6 and the top frame 601. As the sealing plug 6 moves, the top layer of polishing slurry with the largest particles is delivered first. As the polishing slurry is output, the distance between the sealing plug 6 and the top frame 601 decreases, allowing the end of the connecting pipe 501 to move below the top frame 601 and between the next frame 601 to deliver the second stage of polishing slurry. This automatic replacement of the polishing slurry facilitates more precise polishing of the bearing rings, improving polishing efficiency.

[0105] As an optional embodiment, the liquid inlet assembly further includes:

[0106] Multiple sets of built-in electromagnet plates 701, multiple built-in electromagnet plates 701 are grouped together, the built-in electromagnet plates 701 in the same group are arranged in a linear array, and the built-in electromagnet plates 701 in the same group are fixed to the bottom of the same frame 601.

[0107] Multiple sets of built-in magnet plates 702, multiple built-in magnet plates 702 are grouped together, the built-in magnet plates 702 in the same group are arranged in a linear array and fixed to the bottom of the same frame 601, the gap between the built-in magnet plates 702 and their adjacent built-in electromagnet plates 701.

[0108] The built-in electromagnet plate 701 and the built-in magnet plate 702 can move closer and further apart under the action of the electromagnet. This allows the built-in electromagnet plate 701 and the built-in magnet plate 702 to be kept away from the exposed space when the polishing liquid is fed into the liquid tank 5, which facilitates liquid feeding and multi-stage filtration. When the polishing liquid is discharged from the liquid tank 5, the built-in electromagnet plate 701 and the built-in magnet plate 702 are in contact with each other. Under the negative pressure during the discharge, the sealing plug 6 can be moved downward, which in turn pushes the frame 601 downward, thereby automatically realizing the switching of multi-stage polishing liquid.

[0109] As an optional embodiment, the liquid inlet assembly further includes:

[0110] The inclined surfaces 8, the bottom ends of the built-in electromagnet plate 701 and the top ends of the built-in magnet plate 702 are all set as inclined surfaces 8, and the fitted inclined surfaces 8 are compatible with each other. Anti-corrosion rubber layers are fixed on the inclined surfaces 8.

[0111] The inclined surface 8 increases the contact area when the built-in electromagnet plate 701 and the built-in magnet plate 702 are attached, and the anti-corrosion rubber layer improves the sealing effect.

[0112] As an optional embodiment, the multi-stage filter 602 includes:

[0113] The frame is fixed to the top of the multi-stage filter 602;

[0114] A ring frame is fixed at the center of the multi-stage filter screen 602 and surrounds the connecting pipe 501;

[0115] The frame design improves the support effect when the multi-stage filter 602 moves under negative pressure, and the ring frame design allows the multi-stage filter 602 to slide along the connecting pipe 501 to improve the sealing effect.

[0116] Working principle of this invention: The operator places the bearing ring to be polished in the designated position, then starts the cylinder 102, which drives the horizontal plate 103 to move downwards. The horizontal plate 103 drives the rotating shaft 104 to move downwards, causing the rotating shaft 104 to drive the positioning switching component downwards. This moves the positioning switching component to the center of the bearing ring, whereby the bearing ring is positioned. First, the inner ring of the bearing ring is positioned. Then, the first motor 105 is started. After starting, the first motor 105 directly drives the rotating shaft 104 to rotate via the output shaft, or drives the rotating shaft 104 to rotate via the transmission of the drive gear, thereby driving the rotating shaft 104 to rotate. The rotating shaft 104 then drives the positioning switching component. The component rotates, thereby driving the bearing ring to rotate. After the bearing ring rotates, it cooperates with the positioning switching component to polish the outer surface of the bearing ring. During the polishing process, the liquid inlet component delivers chemical mechanical polishing fluid to the polishing position to assist the polishing process. Then, the first motor 105 stops, and the positioning switching component is started to switch, so that the outer wall of the bearing ring is positioned and fixed. When the first motor 105 restarts, it drives the rotating shaft 104 to rotate again. The rotation of the rotating shaft 104 drives the positioning switching component to rotate and polish the inner wall of the bearing ring, thereby realizing the automatic switching polishing of the inner ring side wall and the outer ring side wall of the bearing ring, thereby improving the processing efficiency of the bearing ring.
