Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a grinding device for bearing processing. Background Technology

[0002] As an indispensable basic component in mechanical equipment, the quality of bearing processing directly affects the operating accuracy, stability, and service life of the equipment. Grinding is a crucial step in bearing manufacturing, primarily used for surface treatment of components such as the inner and outer rings to meet technical requirements such as dimensional accuracy and surface roughness.

[0003] For example, a grinding machine for bearing processing, disclosed in CN222903429U, includes a base, a support plate, a cylinder, a frame plate, a motor, a grinding disc, a second motor, and a collar; thereby enabling the bearing to be pre-loaded onto the other collar while the grinding disc grinds the bearing inside one collar, and the collar to be rotated by the second motor after processing, thus achieving rapid switching between loading and unloading.

[0004] In practical use, when the clearance between the bearing and the inner ring of the collar is extremely small, the above-mentioned solution presents several challenges. First, after the bearing is ground inside the collar, some residual grinding dust may remain on its upper surface. When the motor drives the collar to rotate to the unloading position above the guide plate, this residual dust will fall onto the guide plate surface during the subsequent bearing detachment process. Long-term accumulation not only affects the cleanliness of the guide plate but may also cause the bearing to jam when sliding along the guide plate due to dust buildup. Second, because the clearance between the bearing and the inner ring of the collar is small, significant friction is easily generated between them. The residual dust may further exacerbate the adhesion between them, resulting in a delay in the bearing's detachment from the collar. That is, the collar may have reached the unloading position, but the bearing may not be able to detach from the collar in time, requiring additional manual intervention to complete the unloading process. This affects processing efficiency and increases operational complexity. Therefore, a grinding device for bearing processing needs to be designed.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] This utility model provides a grinding device for bearing processing to solve the problems that when the gap between the bearing and the collar is extremely small, residual dust easily falls onto the guide plate and causes jamming, and the friction and adhesion between the two cause the bearing to fall off slowly, requiring manual intervention and affecting efficiency.

[0007] The present invention adopts the following technical solution: a grinding device for bearing processing, mainly comprising a processing table, a dust cover with an opening fixed on the processing table, a guide plate on the processing table, a pushing part for placing the bearing on the processing table, a driving part for driving the pushing part to rotate to a designated processing position on the processing table, and a clamping part for fixing the bearing in the pushing part on the side of the dust cover; a grinding assembly disposed on the dust cover; a dust removal assembly disposed on the processing table and directly below the grinding assembly, the dust removal assembly including a first dust collection part that penetrates the processing table and collects the dust generated during bearing grinding, and a second dust collection part disposed on the grinding assembly for removing dust falling on the bearing surface; and a vibration assembly disposed on the processing table, the vibration assembly being used to perform a tapping action on the pushing part.

[0008] Furthermore, the dust collection unit includes a suction hood that runs through the processing table, a collection net at the top of the suction hood with a size larger than the bearing diameter, a suction pipe at the bottom of the suction hood, a dust collection box on one side of the processing table, a fan on the side of the dust collection box, and one end of the suction pipe connected to the dust collection box.

[0009] Furthermore, the grinding assembly includes a fixing frame fixed on the dust cover, a vertically arranged cylinder two fixed on the fixing frame, the telescopic end of the cylinder two passing through the dust cover, a mounting frame fixed to the telescopic end of the cylinder two, a vertically arranged motor two fixed inside the mounting frame, and a grinding disc fixed to the output end of the motor two passing through the mounting frame.

[0010] Furthermore, the second dust collection unit includes an air guide hood disposed at the bottom of the mounting frame and coaxially fixed with the output end of the second motor. An annular cover is fitted onto the air guide hood, and a dust suction hole is opened on the air guide hood along its circumferential direction. The dust suction hole is located inside the annular cover, and a second dust suction pipe is connected to the annular cover. One end of the second dust suction pipe is connected to the dust collection box.

[0011] Furthermore, the vibration assembly includes a mounting base fixed on the processing table, a vertically arranged motor three fixed on the mounting base, a mounting cover fixed on the processing table, two sets of opposing cams arranged in bearings inside the mounting cover, a crank arm movably arranged between the eccentric positions of the two sets of cams via a connecting shaft, a striking block movably arranged at one end of the crank arm, and a guide hole for guiding the movement of the striking block is provided inside the mounting cover.

[0012] Furthermore, the pushing part includes three sets of connecting arms arranged equidistantly at 120-degree intervals above the processing table. One end of each connecting arm is fixed with a limit ring by a fastener. The driving part includes a motor fixed to the bottom surface of the processing table. The output end of the motor passes through the processing table and is fixed with an indexing plate. A turntable is fixed on the indexing plate. The three sets of connecting arms are equidistantly fixed to the side of the turntable.

[0013] Furthermore, the clamping part includes a mounting bracket that passes through and is fixed to the side of the dust cover. A horizontally arranged cylinder is fixed on the mounting bracket. The axis of the cylinder is horizontally perpendicular to the limiting ring in the processing position. A push plate is fixed to one end of the cylinder. Two sets of guide rods are fixed to the side of the push plate away from the limiting ring. The guide rods are movably disposed through the mounting bracket.

[0014] Furthermore, an anti-slip flexible pad is provided at the contact position between the push rod and the bearing.

[0015] Furthermore, a pressure sensor is embedded in the contact surface between the anti-slip flexible pad and the bearing.

[0016] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0017] A grinding device for bearing processing utilizes a dust collection unit consisting of two dust collection sections. Dust collection section one, through a suction hood, a collection net, and a suction pipe, efficiently collects dust falling downwards during grinding under negative pressure from a fan. Dust collection section two, using a guide hood, an annular hood, and a suction pipe, leverages the airflow generated by a rotating motor and the negative pressure of the fan to remove residual dust from the bearing surface, reducing the amount of dust falling onto the guide plate with the bearing and preventing dust accumulation from affecting bearing sliding or even causing jamming. Simultaneously, a vibration component, through the cooperation of a motor, a cam, a crank arm, and a striking block, strikes a limiting ring, causing it to vibrate. This effectively overcomes the friction caused by the small gap between the bearing and the limiting ring and dust adhesion, allowing the bearing to quickly and smoothly detach from the limiting ring without manual intervention, improving material removal efficiency and ensuring processing continuity and ease of operation.

[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0030] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0031] Reference Figures 1-5As shown in the figure, a bearing grinding device provided in this embodiment of the present invention includes a processing component 1, which includes a processing table 11. A dust cover 12 with an opening is fixed on one side of the processing table 11. The dust cover 12 is used to partially block the dust generated during bearing grinding, reducing the dust from spreading to the surrounding environment. A guide plate 13 is embedded on the other side of the processing table 11. The guide plate 13 has a slanted groove, which can smoothly discharge the ground bearing. A loading plate 14 is embedded on one side of the processing table 11 at the same installation position as the guide plate 13. The loading plate 14 can help the operator to load the bearing more conveniently.

[0032] Furthermore, a material pushing part is provided on the processing table 11. The material pushing part includes three sets of connecting arms 16 arranged at 120-degree intervals on the processing table 11. One end of each connecting arm 16 is fixed with a limiting ring 17 by a fastener. The limiting ring 17 is suitable for placing a bearing, and the top of the limiting ring 17 is flared to facilitate manual feeding. At the same time, a drive part is located on the bottom surface of the processing table 11. The drive part includes a motor 152 fixed to the bottom surface of the processing table 11. The output end of the motor 152 passes through the processing table 11 and is fixed with an indexing plate (not shown in the figure). A turntable 15 is fixed on the indexing plate. The three sets of connecting arms 16 are arranged at 120-degree intervals on the side of the turntable 15. It should be noted that the motor 152 is suitable for driving the turntable 15 to rotate at 120-degree intervals, so that the limiting rings 17 at one end of the three sets of connecting arms 16 rotate sequentially to the processing position, realizing orderly processing of multiple stations.

[0033] like Figures 3-4 and Figure 6 As shown, a clamping part is provided on the side of the dust cover 12 and on the side of the processing position on the processing table 11. The clamping part is used to clamp the bearing in the limiting ring 17. The clamping part includes a mounting bracket 18 that is fixed through and fixed to the side of the dust cover 12. A horizontally arranged cylinder 19 is fixed on the mounting bracket 18. The axis of the cylinder 19 is horizontal and vertical to the limiting ring 17 in the processing position. A push plate 110 is fixed to one end of the cylinder 19. Two sets of guide rods (not shown in the figure) are fixed on the side of the push plate 110 away from the limiting ring 17. The guide rods are movably installed through the mounting bracket 18 and can play a guiding and limiting role when the push plate 110 moves.

[0034] Furthermore, a push rod 111 is fixed on the side of the push plate 110 facing the limiting ring 17. Correspondingly, a through hole 171 adapted to the push rod 111 is provided on the limiting ring 17. The push rod 111 can pass through the through hole 171 and contact the bearing inside the limiting ring 17. An anti-slip flexible pad is provided at the contact position between the push rod 111 and the bearing. It should be noted that a pressure sensor is embedded in the contact surface between the anti-slip flexible pad and the bearing. This sensor can detect the clamping pressure value of the push rod 111 on the bearing in real time. When the cylinder 19 starts the extension and retraction action, the push rod 111 will extend into the limiting ring 17 through the through hole 171. The clamping force is precisely controlled by the pressure data fed back by the pressure sensor, which not only ensures that the bearing will not be displaced during the grinding process, but also avoids the bearing deformation caused by excessive clamping force, thus achieving adaptive and stable clamping for bearings of different specifications.

[0035] like Figure 3 and Figures 5-6 As shown, a grinding assembly 2 is provided on the dust cover 12. The grinding assembly 2 includes a fixing frame 21 fixed on the dust cover 12, and a vertically arranged cylinder 22 fixed on the fixing frame 21. The telescopic end of the cylinder 22 passes through the dust cover 12. A mounting frame 23 is fixed to the telescopic end of the cylinder 22. A vertically arranged motor 24 is fixed inside the mounting frame 23. The output end of the motor 24 passes through the mounting frame 23 and is fixed with a grinding disc 25. When the bearing needs to be ground, the cylinder 22 can drive the mounting frame 23 to move the motor 24 and the grinding disc 25 up and down, adjusting the distance between the grinding disc 25 and the bearing. After the motor 24 is started, it can drive the grinding disc 25 to rotate at high speed, thereby performing grinding operations on the bearing in the processing position.

[0036] like Figure 2 , Figure 4 and Figure 6 As shown, a dust removal component 3 is installed through the worktable 11 and directly below the grinding component 2. This dust removal component 3 includes a dust collection section that penetrates the worktable 11. The dust collection section includes a suction hood 31 that penetrates the worktable 11. A collection net 32 ​​is installed at the top of the suction hood 31. The collection net 32 ​​supports the bearing and is larger than the bearing diameter, ensuring stable bearing placement without hindering dust collection. A suction pipe 33 is connected to the bottom of the suction hood 31. A dust collection box 34 is installed on one side of the worktable 11, and a fan 35 is connected to the side of the dust collection box 34. One end of the suction pipe 33 is connected to the dust collection box 34. When the grinding assembly 2 grinds the bearing, the fan 35 starts, creating a negative pressure inside the suction hood 31. The dust generated during grinding falls into the suction hood 31 through the collection net 32, and is then sucked into the dust collection box 34 through the dust suction pipe 33, thereby effectively collecting the dust generated during the grinding process and preventing dust from spreading and polluting the working environment.

[0037] Meanwhile, a second dust collection unit for removing dust from the bearing surface is provided on the mounting frame 23. The second dust collection unit includes a guide hood 37 located at the bottom of the mounting frame 23 and coaxially arranged with the output end of the second motor 24. The guide hood 37 does not contact the output end of the second motor 24. An annular cover 38 is sleeved on the guide hood 37, and a dust suction hole (not shown in the figure) is opened on the guide hood 37 along its circumferential direction. The dust suction hole is located inside the annular cover 38. A second dust suction pipe 36 is connected to the annular cover 38, and one end of the second dust suction pipe 36 is connected to the dust collection box 34.

[0038] When motor 24 drives the grinding disc 25 to rotate at high speed to grind the bearing, the dust is drawn into the annular cover 38 through the suction hole by the negative pressure of the fan 35, and then sucked into the dust collection box 34 through the suction pipe 36. In conjunction with the dust collection unit, the grinding dust is collected from both the top and bottom, which further improves the dust collection effect and better ensures the cleanliness of the working environment.

[0039] like Figure 5 and Figure 7 As shown, a vibration assembly 4 is installed on the processing table 11 and on one side of the guide plate 13. The vibration assembly 4 is used to strike the side of the limiting ring 17 above the guide plate 13 to assist the bearing inside the limiting ring 17 to fall smoothly. The vibration assembly 4 includes a mounting base 41 fixed on the processing table 11, a vertically arranged motor 42 fixed on the mounting base 41, and a mounting cover 43 fixed on the processing table 11. The bearing inside the mounting cover 43 is provided with two sets of opposing cams 44. A crank arm 45 is movably arranged between the eccentric positions of the two sets of cams 44 through a connecting shaft. A striking block 46 is movably arranged at one end of the crank arm 45, and a guide hole (not shown in the figure) is opened in the mounting cover 43 to guide the movement of the striking block 46.

[0040] When motor 42 starts, it drives cam 44 to rotate. Cam 44 drives striking block 46 to reciprocate along guide hole via crank arm 45, thereby striking the side of limit ring 17, causing limit ring 17 to vibrate. This causes the bearing inside to quickly and smoothly disengage from limit ring 17 and slide down guide plate 13. In addition, in this embodiment, a PLC controller is fixed to the side of processing table 11, which controls the operation of the above-mentioned equipment to realize automated operation.

[0041] Working Principle: First, the operator places the bearing to be processed into one of the limiting rings 17 using the loading plate 14. The flared top of the limiting ring 17 facilitates manual loading. Then, the PLC controller starts motor 152, which drives the indexing plate to rotate, causing the turntable 15 to rotate 120 degrees at intervals, rotating the limiting ring 17 containing the bearing to the processing position. At this time, the PLC controller starts cylinder 19, whose extension / retraction end pushes the push plate 110. The push rod 111 on the push plate 110 passes through the through hole 171 on the limiting ring 17 and contacts the bearing. The pressure sensor on the push rod 111 detects the clamping pressure value in real time and feeds it back to the PLC controller. Based on the feedback data, the PLC controller controls the extension / retraction of cylinder 19, ensuring that the push rod 111 clamps the bearing within the limiting ring 17 with appropriate force. This ensures that the bearing will not shift during subsequent grinding and avoids excessive clamping force that could deform the bearing.

[0042] After clamping is completed, the PLC controller starts cylinder 22, and the telescopic end of cylinder 22 pushes the mounting frame 23 downward. The mounting frame 23 drives motor 24 and grinding disc 25 downward, bringing the grinding disc 25 close to the surface of the bearing to be ground. Then, the PLC controller starts motor 24, which drives the grinding disc 25 to rotate at high speed to perform the grinding operation on the bearing. During the polishing process, the PLC controller controls the start of the fan 35, which creates a negative pressure inside the suction hood 31. Some of the dust generated during polishing falls into the suction hood 31 through the collection net 32 ​​and is then sucked into the dust collection box 34 through the first suction pipe 33. At the same time, when the second motor 24 drives the polishing disc 25 to rotate, it generates airflow. Under the negative pressure of the fan 35, another part of the dust enters the annular hood 38 through the dust suction holes on the air guide hood 37 and is then sucked into the dust collection box 34 through the second suction pipe 36. This achieves comprehensive collection of polishing dust from both the top and bottom, effectively preventing dust from spreading and polluting the working environment.

[0043] After grinding, the PLC controller controls cylinder 22 to move the mounting bracket 23, motor 24, and grinding disc 25 upwards, away from the bearing; simultaneously, it controls cylinder 19 to retract the push plate 110 and push rod 111, releasing the clamping of the bearing. Then, the PLC controller controls motor 152 to rotate the turntable 15 at 120-degree intervals, rotating the limiting ring 17 containing the ground bearing to the dropping position above the guide plate 13. At this time, the PLC controller starts motor 42, which drives cam 44 to rotate. Cam 44, through crank arm 45, drives the striking block 46 to reciprocate along the guide hole in the mounting cover 43, striking the side of the limiting ring 17. The vibration generated by the striking causes the bearing inside to quickly and smoothly detach from the limiting ring 17 and slide down the inclined groove on the guide plate 13, completing the dropping process. The empty limit ring 17 is rotated to the side of the loading plate 14, waiting for the staff to load the material again. This cycle is repeated to realize the automated continuous operation of bearing processing.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
