Description

Technical Field

[0001] This invention relates to the field of bearing assembly technology, and in particular to an automatic assembly device for tapered roller bearings. Background Technology

[0002] Tapered roller bearings are a type of separable rolling bearing, mainly composed of an inner ring, an outer ring, tapered rollers, and a cage. Both the outer surface of the inner ring and the inner surface of the outer ring are designed with tapered raceways. The tapered rollers are evenly distributed between the inner and outer ring raceways through the cage's openings. The cage's function is to precisely guide and constrain the circumferential spacing of the rollers to prevent them from colliding with each other. During assembly, the tapered rollers are first inserted into the cage's openings according to process requirements. Then, the inner ring is pressed axially into the assembly. The cage is then axially pushed using tools to make the inner ring raceway fit against the rollers. Finally, the outer ring and inner assembly are axially aligned and fitted together to complete the overall assembly of the bearing.

[0003] In the traditional assembly process of tapered roller bearings, lubrication is required. However, when lubricating tapered roller bearings by applying lubricating oil, it is difficult to apply lubricant to the gaps and angles due to the small internal clearance and dense distribution of the rollers, resulting in low lubrication efficiency. In existing technologies, rollers are installed into the cage using a roller injection machine, but the installation accuracy of the rollers is difficult to guarantee, affecting the assembly speed of the inner ring. Bearing assembly can only be carried out in a single step sequentially, which is not convenient for combining multiple steps. This causes other equipment to be stopped and waiting while a single step is being carried out, and the waiting time cannot be used to further improve the assembly efficiency of the bearing. Summary of the Invention

[0004] This invention provides an automatic assembly device for tapered roller bearings to solve the problems of low lubrication efficiency in traditional tapered roller bearing assembly processes, where lubrication is required by applying lubricating oil. This is because the small internal clearances and dense roller distribution make it difficult to apply lubricant to the gaps and angles, resulting in low lubrication efficiency. Furthermore, existing technologies use roller injection machines to install rollers onto the cage, but the accuracy of roller installation is difficult to guarantee, affecting the assembly speed of the inner ring. Additionally, bearing assembly can only be performed sequentially in single steps, making it inconvenient to combine multiple steps. This results in other steps being stopped and waiting while a single step is being performed, failing to effectively utilize waiting time to further improve bearing assembly efficiency.

[0005] This invention provides an automatic assembly device for tapered roller bearings, specifically comprising: a bearing assembly table; a shifting drive servo motor fixedly connected above the bearing assembly table; an assembly rotary table fixedly connected to the upper end of the servo motor shaft; four unit rotary tables rotatably connected to the assembly rotary table via bearings; a rotary table toothed ring fixedly connected to the lower edge of each unit rotary table; an internal thread formed on the inner surface of the edge of each unit rotary table; a lubricant storage cylinder installed below each unit rotary table; the upper edge of the lubricant storage cylinder bent outward to form an outer edge; and an outer thread formed on the outer surface of the outer edge. The lubricant storage cylinder is movably connected to an assembly guide platform. The outer surface of the assembly guide platform has a roller guide groove, and the top of the assembly guide platform is machined with a flow divider cavity. The side wall of the assembly guide platform is provided with an atomizing nozzle, the inner end of which is connected to the flow divider cavity. Below the flow divider cavity is an oil guide push tube. The lower end of the oil guide push tube is equipped with a second one-way valve with the outlet facing upward. The center of the bottom surface of the lubricant storage cylinder is vertically connected to an oil guide pressure cylinder. The lower edge of the cylinder wall of the oil guide pressure cylinder is provided with a cylinder end oil inlet. The oil guide pressure cylinder is equipped with a first one-way valve with the inlet facing the cylinder end oil inlet.

[0006] Furthermore, a roller injection machine is connected to the right edge of the upper surface of the bearing assembly platform via a bracket, a shifting motor is fixedly connected to the upper surface of the bearing assembly platform, a shifting gear is fixedly connected to the shaft of the shifting motor, and an inner ring pressing robot is installed at the rear of the bearing assembly platform.

[0007] Furthermore, a splash guard is fixedly connected above the unit rotary disk. The splash guard is an flared cover with the opening facing upwards. An alignment magnetic block is fixedly connected to the inner wall of the splash guard. The alignment magnetic block is made of a permanent magnet.

[0008] Furthermore, the inner wall of the lubricant storage cylinder is provided with guide grooves, which are perpendicular to the bottom surface of the lubricant storage cylinder. A reset top spring is fixedly connected to the bottom surface of the lubricant storage cylinder, and the upper end of the reset top spring is fixedly connected to the inside of the assembly guide platform.

[0009] Furthermore, the oil guide tube is movably connected inside the oil guide cylinder, the oil guide tube is coaxial with the oil guide cylinder, and the inner wall of the oil guide cylinder is tightly fitted with the outer surface of the oil guide tube.

[0010] Furthermore, the lower edge of the assembly guide table is bent to form a lower edge, and a lower edge guide opening is provided on the outer edge of the lower edge. The lower edge of the guide table is slidably connected to the inner wall of the lubricant storage cylinder, and the lower edge guide opening is slidably connected to the guide inner texture. A return hole is longitudinally provided through the lower edge of the guide table.

[0011] Furthermore, the top edge of the assembly guide table is chamfered, and the roller guide groove is a groove with a semi-circular cross-section, with the axis of the roller guide groove perpendicular to the upper surface of the assembly guide table.

[0012] Furthermore, the shift gear meshes with a disc gear ring located near the bottom of the unit disc of the roller injection machine.

[0013] Furthermore, the atomizing nozzle is located at the top inside the roller guide groove.

[0014] This invention provides an automatic assembly device for tapered roller bearings, which has the following advantages: The tapered roller bearing assembly device of this invention is a multi-station rotary assembly table. The rotation of the assembly table facilitates the cyclical flow of bearing components. When the cage flows past the roller injection machine, the rollers are conveyed to the cage by the roller injection machine. The rotation of the cage is continuously adjusted by the constant speed rotation of the rotary table driven by the shifting motor, causing the openings at different positions of the cage to alternately approach the roller injection machine for roller installation. Then, as the shifting drive servo motor rotates, the cage with the completed roller installation is adjusted to below the inner ring pressing robot. The inner ring pressing robot clamps the bearing inner ring and presses it into the cage from top to bottom, causing the rolling elements to roll and connect with the inner ring raceway. Simultaneously, the roller injection machine injects rollers into another cage, allowing the roller injection machine and the inner ring pressing robot to operate synchronously to assemble different bearings. This efficient use of waiting time further improves bearing assembly efficiency.

[0015] In addition, a roller guide groove is provided outside the assembly guide table, which facilitates the stable and accurate entry of the bearing rollers into the cage window when they are injected into the cage by the roller injection machine. The magnetic attraction between the alignment magnetic block and the bearing roller makes the roller fit tightly in the cage window, so that the bearing inner ring can quickly enter the center of the cage during installation, reducing friction with the roller and avoiding the situation where the inner ring cannot be installed due to insufficient precision of the roller installation during the assembly process.

[0016] Furthermore, when the inner ring of the bearing is pressed into the cage by the inner ring press-fitting robot, the assembly guide table applies a downward thrust, pushing the oil guide tube into the oil pressure cylinder, compressing the lubricant inside the oil pressure cylinder, and injecting the lubricant into the distribution chamber. The lubricant is then sprayed outward through the atomizing nozzle, ensuring that the lubricant is evenly sprayed onto the surface of the bearing rollers, achieving automatic lubrication of the rolling elements and cage inside the bearing. Excess lubricant flows back into the lubricant storage cylinder through the return hole, reducing lubricant waste. After the return spring rebounds, the oil guide tube rises, and through the change in volume and the action of the two one-way valves, the lubricant inside the assembly guide table is reintroduced into the oil pressure cylinder, achieving continuous lubricant delivery. This allows for synchronous lubrication during bearing assembly, saving the step of manual lubrication. The radial lubrication method, from the inside out, effectively improves lubrication uniformity and eliminates lubrication dead zones. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. Based on the described 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.

[0022] Example 1: Please refer to Figures 1 to 13 : This invention proposes an automatic assembly device for tapered roller bearings, comprising: a bearing assembly table 1; a shifting drive servo motor 2 fixedly connected above the bearing assembly table 1; an assembly rotary table 3 fixedly connected to the upper end of the shaft of the shifting drive servo motor 2; four unit rotary disks 4 rotatably connected to the assembly rotary table 3 via bearings; a roller injection machine 8 connected to the right edge of the upper surface of the bearing assembly table 1 via a bracket; a shifting motor 7 fixedly connected to the upper surface of the bearing assembly table 1; a shifting gear 701 fixedly connected to the shaft of the shifting motor 7; and an inner ring pressing robot 9 installed at the rear of the bearing assembly table 1. The bearing components circulate through the rotation of the assembly table, and the cage flows past the roller injection machine 8. Rollers are conveyed to the cage by the roller injection machine 8, and the rotation of the cage is continuously adjusted by the uniform rotation of the unit turntable 4 driven by the shifting motor 7. This allows the openings at different positions of the cage to alternately approach the roller injection machine 8 for roller installation. Then, as the shifting drive servo motor 2 rotates, the cage with the rollers installed is adjusted to be below the inner ring pressing robot 9. The inner ring pressing robot 9 clamps the bearing inner ring and presses it into the cage from top to bottom, so that the rolling elements are rolled and connected to the inner ring raceway. At the same time, the roller injection machine 8 injects rollers into another cage, so that the roller injection machine 8 and the inner ring pressing robot 9 operate synchronously to assemble different bearings, making reasonable use of waiting time to improve assembly efficiency.

[0023] In this embodiment, a rotary disc toothed ring 401 is fixedly connected to the lower edge of the unit rotary disc 4. An internal rotary disc thread 404 is formed on the inner surface of the edge of the unit rotary disc 4. A lubricant storage cylinder 5 is installed below the unit rotary disc 4. The upper edge of the lubricant storage cylinder 5 is bent outwards to form an outer edge 502. An outer edge thread 503 is formed on the outer surface of the outer edge 502. The outer edge thread 503 is helically connected to the internal rotary disc thread 404. An assembly guide table 6 is movably connected inside the lubricant storage cylinder 5. The outer surface is provided with roller guide grooves 601. The top of the assembly guide platform 6 is machined with a flow distribution cavity 606. The side wall of the assembly guide platform 6 is provided with an atomizing nozzle 602. The inner end of the atomizing nozzle 602 is connected to the flow distribution cavity 606. Below the flow distribution cavity 606 is an oil guide push pipe 607. The lower end of the oil guide push pipe 607 is equipped with a second one-way valve 608 with the outlet facing upward. The center of the bottom surface of the lubricant storage cylinder 5 is vertically connected to an oil guide pressure cylinder 504. The lower edge of the cylinder wall of the oil guide pressure cylinder 504 is provided with a cylinder end oil inlet 505. The oil guide cylinder 504 is equipped with a first one-way valve 506 with the inlet facing the oil inlet 505 at the cylinder end. The top edge of the assembly guide table 6 is machined with a chamfered structure. The roller guide groove 601 is a groove with a semi-circular cross-section. The axis of the roller guide groove 601 is perpendicular to the upper surface of the assembly guide table 6. The atomizing nozzle 602 is located at the top inside the roller guide groove 601. The setting of the outer edge thread 503 and the inner thread 404 of the rotating disc facilitates the disassembly, lubricant filling, cleaning, and maintenance of the lubricant storage cylinder 5. As the assembly guide platform 6 moves downward under pressure, the oil guide push pipe 607 pushes downward into the oil guide cylinder 504, compressing the lubricant inside the oil guide cylinder 504. The second one-way valve 608 opens, and the first one-way valve 506 closes, injecting the lubricant into the distribution chamber 606. The lubricant is then sprayed outward through the atomizing nozzle 602, so that the lubricant is evenly sprayed onto the surface of the bearing rollers. As the assembly guide platform 6 moves downward, the atomizing nozzle 602 sprays lubricant from top to bottom through the rolling elements, realizing automatic lubrication of the rolling elements and cage inside the bearing.

[0024] In this embodiment, a splash guard 402 is fixedly connected above the unit rotary disk 4. The splash guard 402 is an flared cover with the opening facing upwards. An alignment magnetic block 403 is fixedly connected to the inner wall of the splash guard 402. The alignment magnetic block 403 is made of a permanent magnet. The splash guard 402 can prevent the leakage of lubricant during the spraying process and avoid pollution of the surrounding environment. The alignment magnetic block 403 attracts the rolling element, so that the rolling element fits tightly inside the cage window hole, improving the assembly accuracy of the rolling element.

[0025] In this embodiment, the inner wall of the lubricant storage cylinder 5 is provided with guide grooves 501, which are perpendicular to the bottom surface of the lubricant storage cylinder 5. A reset top spring 507 is fixedly connected to the bottom surface of the lubricant storage cylinder 5. The upper end of the reset top spring 507 is fixedly connected to the inside of the assembly guide platform 6. The oil guide push tube 607 is movably connected to the inside of the oil guide pressure cylinder 504. The oil guide push tube 607 is coaxial with the oil guide pressure cylinder 504, and the inner wall of the oil guide pressure cylinder 504 is tightly fitted with the outer surface of the oil guide push tube 607. When the assembly guide platform 6 is pressed down by pressure, it resets... Under the rebound action of the top spring 507, the oil guide push tube 607 rises and slides upward inside the oil guide pressure cylinder 504, increasing the internal volume of the oil guide pressure cylinder 504. At this time, the diversion chamber 606 closes and the first one-way valve 506 opens, allowing the lubricant inside the lubricant storage cylinder 5 to pass through the cylinder end oil inlet 505 and the first one-way valve 506 into the oil guide pressure cylinder 504 for storage. Through the change in volume and the action of the two one-way valves, the lubricant inside the assembly guide table 6 is reintroduced into the oil guide pressure cylinder 504, achieving continuous lubricant delivery.

[0026] In this embodiment, the shift gear 701 meshes with the disc tooth ring 401 at the bottom of the unit disc 4 near the roller injection machine 8. When the unit disc 4, on which the cage is placed, rotates to the rightmost end of the assembly table 3 under the drive of the shift drive servo motor 2, the disc tooth ring 401 meshes with the shift gear 701 to achieve gear transmission. The shift motor 7 can drive the unit disc 4 to rotate at a constant speed. The constant speed rotation of the unit disc 4 cooperates with the roller injection machine 8 to input rolling elements into different windows of the cage.

[0027] In Example 2, based on Example 1, the lower edge of the assembly guide platform 6 is bent to form a lower edge 603. The outer edge of the lower edge 603 has a lower edge guide opening 604. The lower edge 603 is slidably connected to the inner wall of the lubricant storage cylinder 5. The lower edge guide opening 604 is slidably connected to the guide inner texture 501. The lower edge 603 has a longitudinally penetrating return hole 605. After the lubricant is sprayed, excess lubricant flows downward and gathers above the lower edge 603 of the guide platform, and then flows back into the lubricant storage cylinder 5 through the return hole 605, so that the lubricant circulates and reduces the waste of lubricant.

[0028] The working principle of this embodiment is as follows: First, the shift drive servo motor 2 is turned on, which drives the assembly rotary table 3 to rotate intermittently counterclockwise, with a single rotation angle of 90 degrees. The bearing cage is placed above the unit rotary table 4 located in front and fitted onto the assembly guide table 6. Driven by the shift drive servo motor 2, the unit rotary table 4 moves to a position close to the roller injection machine 8, so that the rotary table gear ring 401 meshes with the shift gear 701 to form a gear transmission. The roller injection machine 8 conveys the rollers to the cage, and the shift motor 7 drives the unit rotary table 4 to evenly distribute the rollers. The high-speed rotation continuously adjusts the cage rotation, causing the openings at different positions on the cage to alternately approach the roller injection machine 8 for roller installation. After the roller installation is completed, the bearing carrier, driven by the shifting drive servo motor 2, adjusts the cage with the completed roller installation to below the inner ring pressing robot 9. The inner ring pressing robot 9 clamps the bearing inner ring and presses it into the cage from top to bottom, making the rolling elements roll and connect with the inner ring raceway. At the same time, the roller injection machine 8 injects rollers into another cage, so that the roller injection machine 8 and the inner ring pressing robot 9 operate synchronously to assemble different bearings. During the inner ring installation process, the assembly guide table 6 moves downward, causing the oil guide tube 607 to advance into the oil pressure cylinder 504, compressing the lubricant inside the oil pressure cylinder 504 and injecting it into the distribution chamber 606. The lubricant is then sprayed outward through the atomizing nozzle 602, ensuring even lubrication of the bearing rollers and achieving automatic lubrication of the bearing's internal rolling elements and cage. Excess lubricant flows back to the lubricant storage cylinder 5 through the return hole 605, reducing lubricant waste. After the inner ring pressing robot 9 releases the bearing inner ring and moves upward to retract, the assembly guide table 6 is reset by the return spring 50. 7. The elastic force moves upward, causing the oil guide tube 607 to rise. Through the change in volume and the action of the two one-way valves, the lubricant inside the assembly guide table 6 is reintroduced into the oil guide cylinder 504, achieving continuous lubricant delivery. This allows for synchronous lubrication during bearing assembly, saving the step of manual lubrication. When the assembly guide table 6 moves upward, it simultaneously pushes the bearing inner ring, bearing cage, and rolling elements together upward. As the shift drive servo motor 2 continues to rotate, the components are transported forward for easy manual collection. Finally, the bearing outer ring is fitted onto the cage, completing the assembly of the tapered roller bearing.
