Description
Technical Field
[0001] This invention relates to the field of bearing processing technology, specifically to a bearing processing device with measurement accuracy function. Background Technology
[0002] Bearings are essential components in modern machinery. Their primary function is to support rotating parts of the machine, reduce the coefficient of friction during movement, and ensure rotational accuracy. The precision, performance, lifespan, and reliability of bearings play a decisive role in the precision, lifespan, and reliability of the host machine. With the ever-increasing precision requirements of modern industry for machinery, the machining accuracy of bearings, as a core fundamental component, directly affects the overall operational quality and service life of the equipment. Among these processes, the grinding of the inner and outer rings of the bearing is a critical step in determining the dimensional accuracy and surface finish of the bearing, requiring extremely high precision.
[0003] In the grinding process of bearing inner and outer rings, machining accuracy is a core indicator for measuring the quality of the finished bearing. A common problem in bearing inner and outer ring grinding operations is the inconvenience of clamping, positioning, and changing fixtures. Existing equipment has independent processing and inspection stations, requiring the complete disassembly of the workpiece from the grinding equipment, replacement of fixtures, or switching of processing stations to achieve a change in clamping for inner and outer ring grinding. This necessitates multiple disassemblies and repeated clamping during grinding, transportation, and inspection. Each positioning of the thin-walled annular part introduces new clamping deviations and positioning errors, exacerbating dimensional deviations in the grinding process itself and significantly reducing the accuracy of subsequent dimensional inspection data.

Each clamping module consists of a main clamping block and adaptively rotatable side clamping blocks, with a return spring providing elastic assisted clamping. For two different processing conditions—outer ring grinding and inner ring grinding of bearing components—the clamping modules can be switched by a cylinder driving them to converge and expand: when clamping the outer ring, the side clamping blocks can adaptively expand and rotate according to the outer ring diameter, forming a multi-point contact clamping with the main clamping block; when clamping the inner ring, the clamping modules can extend into the inner ring and adaptively conform to the inner ring wall, effectively solving the problems of traditional tooling that can only clamp the inner and outer rings individually, has limited bearing specifications, and poor clamping fit.

Simultaneously, a first drive unit rotates the ladder platform and the grinding wheel synchronously, crushing and breaking down metal debris of varying sizes. Larger pieces are refined into acceptable particle sizes and then sieved before being sent to the outlet bin. Combined with a negative pressure airflow generated by a power pump, the sieved debris is transported to a recycling device for centralized recovery and reuse. This structure solves the problems of debris accumulation, difficult cleaning, and dust pollution associated with traditional grinding equipment. It also prevents large debris from entering the power pump and causing wear, blockage, and damage to internal components, effectively reducing equipment failure rates and maintenance costs.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] Please see Figures 1-14 The present invention provides a technical solution: a bearing processing device with measurement accuracy function, including a worktable 1, a conveying mechanism 2 mounted on the worktable 1, a transfer mechanism 3 mounted on one side of the conveying mechanism 2, a clamping mechanism 4 mounted on the other side of the transfer mechanism 3, and a grinding robot 5 mounted on the worktable 1 in conjunction with the clamping mechanism 4. The conveying mechanism 2 is used to convey the bearing part 6 to be processed, the transfer mechanism 3 is used to grab the bearing part 6 on the conveying mechanism 2 and transfer it to the clamping mechanism 4, the clamping mechanism 4 is used to clamp and position the inner ring or outer ring of the bearing part 6 according to the processing requirements, and the grinding robot 5 is equipped with a size detection sensor to detect the processing accuracy while processing the bearing part 6.
[0025] Optionally, the size detection sensor is a laser displacement sensor, which is fixed to the end of the grinding robot 5 and scans the bearing ring surface synchronously with the robot.
[0026] The clamping mechanism 4 includes a rotary table 41. The upper surface of the rotary table 41 is provided with a mounting groove 411. The bottom of the mounting groove 411 is provided with a cross groove 412. Four sets of first guide rails 413 are fixed in the cross groove 412. A first cylinder 414 is fixed on the upper side of the first guide rail 413. The first cylinder 414 is close to the edge of the mounting groove 411. The driving end of the first cylinder 414 is connected to a sliding seat 415. The sliding seat 415 slides with the first guide rail 413. A clamping module 42 is fixed on the sliding seat 415.
[0027] The clamping module 42 includes a main clamping block 421. The main clamping block 421 has through slots 4211 on both sides. A pin 422 is fixed in the through slot 4211. A hinge sleeve 423 is rotatably sleeved on the surface of the pin 422. The other end of the hinge sleeve 423 is connected to a side clamping block 424. Return springs 425 are sleeved on both ends of the pin 422. The main clamping block 421 has corresponding receiving slots 4212 to cooperate with the return springs 425. One end of the return spring 425 is connected to the hinge sleeve 423, and the other end of the return spring 425 is connected to the surface of the receiving slot 4212, and a force sensor is provided at the connection end.
[0028] Optionally, the force sensor may be a miniature thin-film pressure sensor.
[0029] The following is a supplementary explanation based on the above structure: Both the main clamping block 421 and the side clamping blocks 424 are designed with an arc shape. Under the elastic force of the return springs 425 on both sides, the outer ends of the two side clamping blocks 424 bend and move closer to the main clamping block 421. The height of the first guide rail 413 is consistent with the surface height of the mounting groove 411, and the bearing 6 is placed at the center of the mounting groove 411. When the outer ring needs to be clamped, the first cylinder 414 pushes the sliding seat 415 along the first guide rail 413 toward the bearing 6 in the central area. Each main clamping block 421 is tightly attached to the outer ring surface of the bearing 6. The side clamping blocks 424 are affected by the diameter of the outer ring of the bearing 6 and are spread apart by the outer ring surface, rotating to different degrees relative to the main clamping blocks 421. At the same time, under the action of the return springs 425, they can assist in clamping on both sides of the main clamping block 421. When inner ring clamping is required, the transfer mechanism 3 first grabs the bearing component 6 away from the rotary table 41, and the first cylinder 414 drives each set of clamping modules 42 to converge towards the center; then the transfer mechanism 3 lowers the bearing component 6, so that multiple sets of clamping modules 42 are placed inside the inner ring of the bearing component 6, and then the first cylinder 414 drives the clamping modules 42 to expand outward, the main clamping block 421 contacts the inner ring surface of the bearing component 6, and the side clamping block 424 rotates adaptively or remains unchanged according to the inner ring specifications.
[0030] In one embodiment, a plurality of guide grooves 4121 are provided at the bottom of the central region of the cross groove 412. A collection cover 43 is fixed at the bottom of the rotary table 41 corresponding to the guide grooves 4121. The upper side of the collection cover 43 is open. A first driver 44 is connected to the bottom of the collection cover 43. An outer cover 45 is provided at the bottom of the collection cover 43. The outer cover 45 is connected and fixed to the internal support of the workbench 1 through the support frame 7. The collection cover 43 and the outer cover 45 are rotatably engaged. An inner cover 46 is sleeved on the outside of the drive shaft of the first driver 44. An annular base plate 47 is connected to the bottom of the outer cover 45.
[0031] The collection cover 43 has several connecting grooves 431 circumferentially formed in the area between the outer cover 45 and the inner cover 46. Inside the collection cover 43, a guide platform 432 is provided in conjunction with the connecting grooves 431. The guide platform 432 is narrow at the top and wide at the bottom, and is used to guide the impurities falling from above to the connecting grooves 431, and then fall to the upper side of the annular bottom plate 47 between the outer cover 45 and the inner cover 46.
[0032] Furthermore, the inner cover 46 is connected to a ladder 461. A chip inlet channel is provided between the lower surface of the ladder 461 and the annular base plate 47. A rolling wheel 462 is provided at the bottom of the ladder 461. A gap is left between the lower surface of the rolling wheel 462 and the annular base plate 47. The inclined side of the ladder 461 is the chip inlet side, and the vertical side of the ladder 461 is the chip outlet side. An outlet 471 is opened on the surface of the annular base plate 47, and a screen is provided at the outlet 471.
[0033] It should be further explained that the first driver 44 is mounted on a bracket on the lower side of the workbench 1. The first driver 44 is used to drive the rotary table 41 to rotate via the collecting cover 43, and simultaneously drive the ladder platform 461 to rotate via the inner cover 46, while the outer cover 45 and the annular base plate 47 remain stationary. The ladder platform 461 rotates synchronously with the inner cover 46, and the metal shavings accumulated on the annular base plate 47 flow into the shavings inlet channel from the shavings inlet side of the ladder platform 461. The crushing roller 462 squeezes and crushes the shavings to reduce their volume, and shavings of the acceptable particle size can pass through the screen.
[0034] Furthermore, the bottom of the outer casing 45 is connected to a bottom cover 48. The bottom cover 48 is equipped with baffles on both sides of the outlet 471, and the space between the two baffles is set as an outlet compartment. The bottom cover 48 has an outlet port 481 corresponding to the outlet compartment. The outlet port 481 is connected to a recycling and processing device through a pipeline, and a power pump is installed on the pipeline.
[0035] In actual operation, the processing of bearing component 6 will generate metal impurities of varying sizes. During processing, the power pump continuously draws air, creating a negative pressure environment in the outlet chamber. The rotating platform 461 crushes the debris on the annular base plate 47, breaking it down to a size that can pass through the screen. After passing through the screen and falling into the outlet chamber, the debris is transported by the airflow to the recycling and processing device. This facilitates the centralized recycling of debris and prevents large pieces of debris from entering the power pump and causing damage to internal components. The negative pressure can be simultaneously transmitted to the inside of the collection hood 43, where the metal debris generated during processing is actively absorbed through the guide groove 4121 by the negative pressure.
[0036] The transfer mechanism 3 includes an x-axis moving module 31, a y-axis moving module 32, and a z-axis moving module 33. The y-axis moving module 32 is located at the drive end of the x-axis moving module 31, and the z-axis moving module 33 is located at the drive end of the y-axis moving module 32. A mounting plate 34 is fixed to the drive end of the z-axis moving module 33. A second driver 35 is fixed to one side of the mounting plate 34. A swing arm 36 is connected to the drive end of the second driver 35, and a pneumatic suction cup 37 is provided at the other end of the swing arm 36.
[0037] In actual operation, the x-axis moving module 31, y-axis moving module 32 and z-axis moving module 33 are all linear slide modules. The preferred drive structure is a motor screw drive structure, but it is not limited to this. The conveying mechanism 2 adopts a motor pulley conveying structure.
[0038] The input side of the conveying mechanism 2 is provided with a sorting mechanism 8, which includes a vibrating plate 81. The discharge side of the vibrating plate 81 is provided with a discharge platform 82. A sorting module 83 is mounted on the upper side of the discharge platform 82. A discharge conveyor belt 84 is provided on the discharge side of the discharge platform 82.
[0039] Optionally, a discharge trough 821 is provided on the discharge platform 82 in conjunction with the outlet side of the vibratory feeder 81. A transfer trough 822 is provided at the other end of the discharge trough 821. A transfer block 823 is slidably arranged in the transfer trough 822. A positioning groove is provided on the transfer block 823 for positioning the bearing component 6. A second cylinder 824 is connected to the other end of the transfer block 823.
[0040] The sorting module 83 includes a dual-axis drive assembly 831, which is mounted above the discharge platform 82 and spans the transfer trough 822 and the discharge conveyor belt 84. The drive end of the dual-axis drive assembly 831 is equipped with a suction nozzle 832. The dual-axis drive assembly 831 is used to adjust the height of the suction nozzle 832 and control the movement of the suction nozzle 832 between the discharge conveyor belt 84 and the transfer trough 822 to complete the suction, lifting and cross-station transfer of the bearing component 6.
[0041] It should be further explained that the sorting module 83 is equipped with a preliminary inspection sensor, which is a visual image sensor, to detect whether the bearing part 6 meets the precision machining requirements. If it does not meet the requirements, it will be transferred to the discharge conveyor belt 84 after being transferred by the discharge conveyor belt 84. The bearing part 6 that meets the requirements is transferred to the conveying mechanism 2, and the transfer method is not unique. The second cylinder 824 can drive the transfer block 823 to slide linearly back and forth inside the transfer groove 822, thereby pushing the bearing part 6 sent from the discharge groove 821 to the picking station of the sorting module 83.
[0042] The specific processing method is as follows: Step 1: Automatic workpiece sorting and pre-processing. The bearing parts 6 to be processed are discharged in an orderly manner via the vibratory feeder 81 and conveyed along the discharge chute 821 to the positioning slot of the transfer block 823 in the transfer chute 822, completing the initial positioning of the workpiece. Subsequently, the second cylinder 824 drives the transfer block 823 to slide linearly, pushing the positioned bearing parts 6 to the picking station of the sorting module 83. The dual-axis drive assembly 831 drives the suction nozzle 832 to complete lifting and translating operations, accurately picking up the bearing parts 6 at the station. Simultaneously, the onboard vision image sensor initiates the initial inspection process, real-time detecting the appearance integrity, placement posture, and blank specifications of the bearing parts 6, screening out qualified workpieces that meet the precision machining requirements. Unqualified workpieces are automatically discharged via the discharge conveyor belt 84, preventing defective workpieces from entering the processing station and ensuring the effectiveness of subsequent processing. The bearing parts 6 that pass the initial inspection are transferred from the sorting module 83 to the feeding end of the conveyor mechanism 2, and smoothly conveyed to the designated picking station via the motor pulley conveyor structure.
[0043] Step Two: Precise Transfer of Workpiece Across Workstations. The transfer mechanism 3 starts operation, with the three-axis linear slide module (x-axis movement module 31, y-axis movement module 32, and z-axis movement module 33) working in tandem to precisely adjust the spatial position of the mounting plate 34, driving the swing arm 36 and the end pneumatic suction cup 37 to the workpiece picking position of the conveying mechanism 2. The pneumatic suction cup 37 uses negative pressure to fix the bearing component 6, ensuring stable and non-deviation-free picking. Subsequently, the three-axis modules work in reverse, precisely transferring the bearing component 6 to the center position of the mounting slot 411 on the rotary table 41 of the clamping mechanism 4, completing the workpiece loading and positioning, preparing for subsequent clamping and positioning.
[0044] Step 3: Adaptive inner and outer ring clamping and positioning. Based on the part of the bearing component 6 to be processed (inner or outer ring), the clamping state of the four clamping modules 42 is adaptively adjusted. The clamping pressure is monitored in real time by force sensors throughout the process to achieve precise elastic clamping and positioning.
[0045] If the outer ring of bearing component 6 is to be ground: the first cylinder 414 drives the sliding seat 415 to slide along the first guide rail 413 toward the center of the mounting groove 411, which drives each clamping module 42 to move closer to the workpiece in sync, so that the main clamping block 421 is tightly attached to the surface of the bearing outer ring; the bearing outer ring squeezes the side clamping block 424, causing the side clamping block 424 to rotate adaptively around the pin shaft 422 and open, while the return spring 425 generates a reverse elastic constraint force, so that the side clamping block 424 assists in attaching to both sides of the bearing outer ring, forming a multi-point elastic clamping and positioning. The force sensor collects clamping pressure data in real time to avoid the workpiece being offset by excessively loose clamping or damaged by excessively tight clamping.
[0046] If the inner ring of bearing component 6 is to be ground: firstly, the transfer mechanism 3 grabs the bearing component 6 and temporarily lifts it away from the rotary table 41. The first cylinder 414 drives each set of clamping modules 42 to converge and retract towards the center. Then, the bearing component 6 is lowered so that the clamping module 42 extends into the inner ring area of the bearing. Then, the first cylinder 414 pulls the clamping module 42 to expand outward so that the main clamping block 421 fits against the inner ring wall of the bearing. The side clamping block 424 adaptively and finely adjusts its rotation according to the specifications of the inner ring of the bearing. With the help of the return spring 425, the inner ring is elastically fitted and clamped, realizing the adaptive and precise positioning of the inner ring of bearings of different specifications.
[0047] Step Four: Rotary Grinding and Online Precision Inspection. After the workpiece is clamped and positioned, the first driver 44 is activated, driving the collection cover 43 to rotate the rotary table 41 at a uniform speed, so that the clamped and fixed bearing part 6 rotates synchronously with the rotary table 41. At the same time, the grinding robot 5 starts grinding operations. The laser displacement sensor mounted on the end of the grinding robot 5 moves synchronously with the processing feed, scanning the inner or outer ring surface of the bearing part 6 in real time, and dynamically collecting precision data such as processing dimensions, roundness, and surface flatness. During the processing, the system dynamically corrects the processing trajectory of the grinding robot 5 based on the precision data fed back by the sensor in real time, avoiding processing defects such as uneven grinding, dimensional deviations, and roundness deviations, realizing the simultaneous performance of grinding and precision inspection, and completing the high-precision finishing operation of the bearing part 6.
[0048] Step 5: Simultaneous Crushing, Recycling, and Dust Removal of Processing Debris. Throughout the bearing grinding process, the power pump outside the bottom cover 48 continuously draws air, creating a negative pressure environment inside the outlet chamber, connecting groove 431, and collection cover 43. Under the negative pressure adsorption, the metal debris generated during grinding quickly flows into the collection cover 43 through the guide groove 4121 of the rotating table 41. After being guided by the guide table 432, it falls onto the upper side of the annular bottom plate 47 through the connecting groove 431. Simultaneously, the first driver 44 synchronously drives the inner cover 46 and the ladder 461 to rotate. During the rotation of the ladder 461, metal debris of varying sizes accumulated on the annular bottom plate 47 enters the chip inlet channel from the chip inlet side. The bottom crushing wheel 462 squeezes and crushes the large debris, reducing its volume. After crushing, the sized fragments are screened through a screen at outlet 471 and fall into the outlet chamber of the bottom cover 48. Finally, under the action of negative pressure airflow, they are transported through outlet 481 and pipeline to the recycling and processing device for centralized recovery. This step can clean up the processing fragments in real time, avoiding the accumulation of fragments that affect processing accuracy and scratch the workpiece.
