Description

Technical Field

[0001] This invention belongs to the technical field of tapered bearing ring testing devices, specifically a tapered bearing ring outer wall precision testing device. Background Technology

[0002] Tapered roller bearings are key components in heavy equipment and precision transmission systems. The geometric accuracy of the outer wall of their raceways (including dimensional tolerances, form tolerances, and positional tolerances) is a core factor determining the bearing's rotational accuracy, load-bearing capacity, and service life. Currently, non-contact optical measurement technologies such as laser scanning have become the mainstream methods for accuracy testing in this field.

[0003] Current production lines generally adopt a simple sequential model of "cleaning process" and "inspection process," seriously neglecting the contamination risk in the material transfer process between the two processes. After the rings reach a clean state in the previous cleaning process, their precision outer walls inevitably suffer secondary contamination in the final stage of being transferred through the material channel to the laser inspection station. The main sources of contamination are oil mist, coolant aerosols, and grinding dust that are suspended in the workshop environment for a long time. These continuously settle and adhere to the surface of the transfer medium, forming a complex mixture of contaminants. When the cleaned rings roll or slide in contact with the contaminated material channel surface, the contaminants are transferred to the outer wall of the rings through direct contact, forming a randomly distributed, unevenly thick composite oil film and particle adhesion layer. This secondary contamination causes irregular specular reflection and refraction, resulting in a large amount of noise in the signal received by the laser sensor. The collected surface three-dimensional point cloud data is severely distorted, directly leading to errors in the measurement of key geometric parameters such as size, roundness, and contour, thus affecting the inspection results. Therefore, the present invention provides a device for detecting the accuracy of the outer wall of a tapered bearing ring. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a tapered bearing ring outer wall precision detection device, comprising a detection table and detection equipment for precision detection of the outer wall of the ring; The top of the testing station is provided with a conveyor belt, a guide platform, a fixed shaft and a guide plate. The conveyor belt is rotatably installed inside the testing station by a drive assembly, and limit rods are evenly distributed on the outer wall of the conveyor belt. The guide plate and the fixed shaft are respectively arranged on both sides of the guide table. A fixing component is installed inside the fixed shaft. A connecting shaft is connected to the outer wall of the fixed shaft. A first rotating shaft is embedded in the connecting shaft. A first motor is fixedly installed at the end of the first rotating shaft away from the connecting shaft. A cleaning cloth is installed inside the testing station and is located below the testing equipment. The two ends of the cleaning cloth are respectively installed on the outer walls of the unwinding roller and the winding roller. A top pressure plate and a pressure roller are provided on the outer wall of the cleaning cloth. A fixing seat is provided at the bottom of the top pressure plate and the fixing seat is fixedly installed inside the testing station.

[0006] A limiting plate is elastically installed inside the testing station, and the limiting plate is located on one side of the guide table.

[0007] The fixed base and the top pressure plate are elastically connected.

[0008] The fixing component includes a frustum, a first wedge, and a fixing block disposed within a fixing shaft. The first wedge is fixedly installed on the outer wall of the frustum. The first wedge and the fixing block are both evenly distributed in a ring array. One side of the frustum is fixedly connected to the connecting shaft.

[0009] The drive assembly includes conveyor wheels embedded at both ends inside the conveyor belt, and a fourth rotating shaft is fixedly installed in each of the two conveyor wheels. Both of the fourth rotating shafts are rotatably installed in the detection table. The testing platform is equipped with a second motor, the output end of which is fixedly connected to a second rotating shaft. A fourth gear is fixedly installed at the top of the second rotating shaft, and a fifth gear meshes with one side of the fourth gear. A third rotating shaft is fixedly installed inside the fifth gear, and the third rotating shaft is connected to one of the fourth rotating shafts via a pulley set.

[0010] The bottom of the fourth gear is fixedly connected to a second guide plate, and a second wedge is provided on one side of the second guide plate. The second wedge is fixedly installed on one side of the limiting plate.

[0011] An installation plate is slidably installed inside the guide platform. Push rods are evenly installed on the outer wall of the installation plate. A third wedge is provided at one end of the installation plate. A third guide plate is provided on the outer wall of the third wedge. The third guide plate is fixedly installed on one side of the limiting plate.

[0012] A connecting plate is rotatably mounted on the outer wall of the connecting shaft. A fourth wedge is fixedly connected to the bottom of the connecting plate. A fourth guide plate is provided on the top of the fourth wedge. The fourth guide plate is fixedly mounted on the outer wall of the limiting plate. A connecting block is fixedly installed on the outer wall of the first rotating shaft, and both the first rotating shaft and the connecting block are slidably connected to the connecting shaft.

[0013] A third gear is fixedly installed on the outer wall of the first rotating shaft. The bottom of the third gear meshes with a second gear, and the bottom of the second gear meshes with a first gear. The first gear is fixedly installed at one end of the take-up roller.

[0014] The beneficial effects of this invention are as follows: 1. The tapered bearing ring outer wall precision testing device of the present invention cleans the ring by contacting a cleaning cloth at its bottom during rotation. In operation, the tapered bearing ring is first placed on top of the testing platform and placed on the outer wall of a limiting rod. A conveyor belt moves the limiting rod, transporting the ring towards the testing equipment. When the ring reaches the guide platform, it is guided by the guide platform and guide plate to move below the testing equipment and be placed on the outside of a fixed shaft. Finally, a first motor drives a first rotating shaft to rotate. The rotation of the first rotating shaft drives the rotation of a connecting shaft, which in turn drives the rotation of the fixed shaft, causing the fixed shaft to rotate and thus rotating the ring, thereby testing the outer wall precision of the entire ring. During the rotation, the entire outer wall of the ring comes into contact with the surface of the cleaning cloth for cleaning, preventing impurities on the ring surface from causing irregular mirror reflections and refractions, which could ultimately affect the test results. Cleaning and testing are performed simultaneously, which helps improve the accuracy of the outer wall precision measurement.

[0015] 2. The tapered bearing ring outer wall precision inspection device of the present invention uses a take-up roller to intermittently rotate and roll up a cleaning cloth. During operation, the rotation of the first rotating shaft drives the rotation of the third gear, which in turn drives the rotation of the second gear, which in turn drives the rotation of the first gear, which in turn drives the rotation of the take-up roller. As the take-up roller rotates, it rolls up the cleaning cloth, continuously providing a fresh cloth surface, avoiding cross-contamination, and ensuring cleanliness for each cleaning. This provides stable and reliable surface pretreatment conditions for the outer wall quality inspection of the ring. Furthermore, by automatically rolling up the cloth during inspection, the operator does not need to frequently stop the machine for inspection and replacement, which helps to achieve continuous production and significantly improves overall efficiency.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] An embodiment of the present invention provides a tapered bearing ring outer wall precision testing device, comprising a testing table 1 and a testing device 2 for precision testing of the outer wall of the ring; The top of the testing platform 1 is provided with a conveyor belt 3, a guide platform 5, a fixed shaft 6 and a guide plate 41. The conveyor belt 3 is installed inside the testing platform 1 by rotating through a drive assembly. Limiting rods 4 are evenly distributed on the outer wall of the conveyor belt 3. The guide plate 41 and the fixed shaft 6 are respectively arranged on both sides of the guide table 5. The fixed shaft 6 has a fixing component installed inside. The outer wall of the fixed shaft 6 is connected to the connecting shaft 7. The first rotating shaft 8 is embedded in the connecting shaft 7. The first motor 9 is fixedly installed at the end of the first rotating shaft 8 away from the connecting shaft 7. A cleaning cloth 13 is installed inside the testing table 1. The cleaning cloth 13 is located below the testing equipment 2. The two ends of the cleaning cloth 13 are respectively installed on the outer walls of the unwinding roller 14 and the winding roller 15. The outer wall of the cleaning cloth 13 is provided with a top pressure plate 18 and a pressure roller 16. A fixing seat 17 is provided at the bottom of the top pressure plate 18. The fixing seat 17 is fixedly installed inside the testing table 1.

[0021] The cleaning cloth 13 is specifically a microfiber dust-free cloth, which has efficient capillary oil absorption and dust locking capabilities, does not shed or fall off, and has good abrasion resistance.

[0022] First, the tapered bearing race (hereinafter referred to as the race) is placed on the top of the testing table 1 and placed on the outer wall of the limiting rod 4. The limiting rod 4 is moved by the conveyor belt 3 to transport the race to the testing equipment 2. When the race moves to the guide table 5, it is guided by the guide table 5 and the guide plate 41 to move to the bottom of the testing equipment 2 and placed on the outside of the fixed shaft 6. Finally, the first rotating shaft 8 is driven to rotate by the first motor 9. When the first rotating shaft 8 rotates, it drives the connecting shaft 7 to rotate. When the connecting shaft 7 rotates, it drives the fixed shaft 6 to rotate, so that the fixed shaft 6 drives the race to rotate, thereby testing the outer wall accuracy of the entire race. As the ring rotates, the entire outer wall of the ring comes into contact with the surface of the cleaning cloth 13 for cleaning. This prevents impurities on the ring surface from causing irregular mirror reflections and refractions, which could ultimately affect the test results. Cleaning and testing are carried out simultaneously, which helps improve the accuracy of the ring outer wall precision measurement.

[0023] A limit plate 19 is elastically installed inside the testing table 1, and the limit plate 19 is located on one side of the guide table 5.

[0024] The position of the collar is limited by the limiting plate 19 to prevent the collar from slipping out of the fixed and detected area due to inertia when it slides on the outer wall of the guide table 5, thus achieving precise positioning and attitude alignment.

[0025] The fixed base 17 and the top pressure plate 18 are elastically connected.

[0026] The top pressure plate 18 presses the cleaning cloth 13 upward in real time, so that the cleaning cloth 13 is evenly attached to the surface of the ring over a large area, ensuring consistent cleaning effect. The cleaning cloth 13 makes flexible contact with the ring, which reduces the rigid impact of the cleaning cloth 13 on the ring rotation system, helps maintain the stability of the ring rotation accuracy, and indirectly improves the stability of the measurement signal.

[0027] The fixing assembly includes a frustum 10, a first wedge 11, and a fixing block 12 disposed within the fixing shaft 6. The first wedge 11 is fixedly installed on the outer wall of the frustum 10. The first wedge 11 and the fixing block 12 are both evenly distributed in a ring array. One side of the frustum 10 is fixedly connected to the connecting shaft 7.

[0028] A rubber pad is installed at the end of the fixing block 12 away from the fixing shaft 6; The rubber pad, as a soft medium, isolates the rigid fixing block 12 from direct contact with the inner wall surface of the collar, avoiding indentations, scratches or roughening caused by contact pressure, thus achieving "non-destructive fixing".

[0029] Furthermore, the rubber pad provides greater tangential friction, preventing slight slippage or circumferential rotation between the collar and the fixing block 12 during high-speed rotation or acceleration / deceleration, thus providing a more stable fixing force.

[0030] The fixed shaft 6 and the connecting shaft 7 are rotatably connected. The fixing block 12 and the fixing shaft 6 are elastically connected by a first spring; When the connecting shaft 7 rotates, it drives the frustum 10 to rotate. When the frustum 10 rotates, it drives the first wedge block 11 to rotate. When the inclined surface of the first wedge block 11 contacts the bottom of the fixing block 12, it forces the fixing block 12 to move outward and contact the inner wall of the collar, thereby fixing it.

[0031] A single rotary drive is all that's needed to complete a stationary motion. It's fast, has a short cycle time, and greatly simplifies the pneumatic, electrical, and control systems.

[0032] The drive assembly includes conveyor wheels 29 embedded at both ends inside the conveyor belt 3. A fourth rotating shaft 30 is fixedly installed in each of the two conveyor wheels 29. Both fourth rotating shafts 30 are rotatably installed in the detection table 1. The testing station 1 is equipped with a second motor 23. The output end of the second motor 23 is fixedly connected to a second rotating shaft 24. A fourth gear 25 is fixedly installed at the top of the second rotating shaft 24. A fifth gear 26 meshes with one side of the fourth gear 25. A third rotating shaft 27 is fixedly installed inside the fifth gear 26. The third rotating shaft 27 is connected to one of the fourth rotating shafts 30 through a pulley set 28.

[0033] The second motor 23 drives the second rotating shaft 24 to rotate. The rotation of the second rotating shaft 24 drives the rotation of the fourth gear 25. The rotation of the fourth gear 25 drives the rotation of the fifth gear 26. The rotation of the fifth gear 26 drives the rotation of the third rotating shaft 27. When the third rotating shaft 27 rotates, it drives one of the fourth rotating shafts 30 to rotate through the pulley group 28. When the fourth rotating shaft 30 rotates, it drives the conveyor belt 3 to rotate through the conveyor wheel 29. When the conveyor belt 3 rotates, it drives the limit rod 4 to move, thereby driving the collar to move to one side of the detection equipment 2 to feed the material.

[0034] The bottom of the fourth gear 25 is fixedly connected to a second guide plate 31, and a second wedge 32 is provided on one side of the second guide plate 31. The second wedge 32 is fixedly installed on one side of the limiting plate 19.

[0035] When the fourth gear 25 rotates, it drives the second guide plate 31 to rotate. When the second guide plate 31 rotates to one side of the second wedge 32, it presses it down. The movement of the second wedge 32 drives the limit plate 19 to move, so that the limit plate 19 slides into the detection table 1. At this time, the guide table 5 can move to discharge material.

[0036] The second guide plate 31 is arranged in a fan shape. When the fourth gear 25 rotates, the second guide plate 31 drives the second wedge block 32 to press down continuously for a period of time, so that the tested ring has enough time to be discharged.

[0037] The teeth on the outer wall of the fourth gear 25 are arranged in a fan shape. The second wedge 32 and the fifth gear 26 are respectively arranged on both sides of the fourth gear 25, so that the feeding and unloading work intermittently.

[0038] The limiting plate 19 is elastically installed in the testing table 1. When the second guide plate 31 separates from the second wedge block 32, the limiting plate 19 moves upward and resets, thus limiting the rings to be tested later.

[0039] An installation plate 33 is slidably installed inside the guide table 5. Push rods 34 are evenly installed on the outer wall of the installation plate 33. A third wedge 35 is provided at one end of the installation plate 33. A third guide plate 36 is provided on the outer wall of the third wedge 35. The third guide plate 36 is fixedly installed on one side of the limiting plate 19.

[0040] The mounting plate 33 and the guide table 5 are elastically connected by a second spring. During material feeding, the limiting plate 19 moves down, causing the third guide plate 36 to move down. After the third guide plate 36 moves down, it releases the limiting effect on the third wedge block 35. The elastic potential energy released by the second spring installed on the outer wall of the mounting plate 33 pushes the mounting plate 33 to move. The movement of the mounting plate 33 causes the push rod 34 to move and slide out from the guide table 5, pushing the collar located on one side of the guide table 5 to assist in material feeding.

[0041] A connecting plate 39 is rotatably mounted on the outer wall of the connecting shaft 7. A fourth wedge 38 is fixedly connected to the bottom of the connecting plate 39. A fourth guide plate 37 is provided on the top of the fourth wedge 38. The fourth guide plate 37 is fixedly mounted on the outer wall of the limiting plate 19. A connecting block 40 is fixedly installed on the outer wall of the first rotating shaft 8, and both the first rotating shaft 8 and the connecting block 40 are slidably connected to the connecting shaft 7.

[0042] During material unloading, the limiting plate 19 moves down, causing the fourth guide plate 37 to move down. When the fourth guide plate 37 moves down, it contacts the fourth wedge block 38, forcing the fourth wedge block 38 to slide away from the fourth guide plate 37. When the fourth guide plate 37 moves, it drives the connecting shaft 7 to move through the connecting plate 39. When the connecting shaft 7 moves, it drives the fixed shaft 6 to move, so that the fixed shaft 6 slides out of the ring and into the testing table 1, which facilitates the unloading of the ring.

[0043] The connecting plate 39 is elastically installed inside the testing table 1 by a third spring. The end of the fixed shaft 6 away from the connecting shaft 7 is arc-shaped. The two work together to help guide the collar to be installed to the outside of the fixed shaft 6.

[0044] A third gear 22 is fixedly installed on the outer wall of the first rotating shaft 8. The bottom of the third gear 22 is meshed with a second gear 21. The bottom of the second gear 21 is meshed with a first gear 20. The first gear 20 is fixedly installed at one end of the take-up roller 15.

[0045] The teeth on the outer wall of the third gear 22 are arranged in a fan shape, which causes the second gear 21 and the first gear 20 to rotate intermittently, thereby causing the take-up roller 15 to rotate intermittently to take up the cleaning cloth 13, thus eliminating the ineffective waste of the cleaning cloth 13. The direction of the cleaning cloth 13 winding is opposite to the direction of the loop rotation, which can form a strong shearing force, effectively scraping away stubborn oil film and embedded particles, and preventing contaminants from being pushed forward on the surface. The rotation of the first rotating shaft 8 drives the rotation of the third gear 22, the rotation of the third gear 22 drives the rotation of the second gear 21, the rotation of the second gear 21 drives the rotation of the first gear 20, and the rotation of the first gear 20 drives the rotation of the take-up roller 15. When the take-up roller 15 rotates, it takes up the cleaning cloth 13, continuously providing a fresh cloth surface, avoiding cross-contamination, ensuring cleanliness for each cleaning, and providing stable and reliable surface pretreatment conditions for the quality inspection of the outer wall of the ring. Furthermore, by automatically rewinding during inspection, operators are no longer required to frequently stop the machine for inspection and replacement, which helps to achieve continuous production and significantly improves overall efficiency.
