Description

Technical Field

[0001] The present invention relates to the technical field of bearing assembly, and particularly to a flexible assembly device for rolling elements of a cylindrical roller bearing. Background Art

[0002] A cylindrical roller bearing is a rolling bearing designed to withstand large radial loads. The rolling elements of a cylindrical roller bearing are cylindrical in shape. The cylindrical rolling elements are an important part of the cylindrical roller bearing, directly affecting the performance and service life of the bearing, enabling them to provide a higher radial load capacity and maintain good performance during high-speed operation. The assembly steps of the cylindrical rolling elements are generally manual. First, a cage is placed inside the outer ring of the bearing, then the cylindrical rollers are individually placed into the pockets of the cage, and finally the inner ring of the bearing is installed. Flexible assembly refers to a manufacturing process that integrates the flexibility, adaptability, and adjustability of a system.

[0003] In the existing patent CN214837942U, an automatic assembly device for rolling elements of a cylindrical roller bearing is disclosed, including a working platform. On the upper surface of the working platform, support columns are fixedly installed near both sides and near the rear surface. On the upper surface of the working platform, near one side and in the middle between the front surface and the rear surface, a first electric telescopic rod is fixedly installed. On the upper surface of the working platform, on the side away from the first electric telescopic rod and in the middle between the front surface and the rear surface, a second electric telescopic rod is fixedly installed.

[0016] The beneficial effects of the present invention are as follows:

[0017] When assembling the rolling elements of the present invention, the outer ring bearing is clamped by the clamping assembly, and the cage is installed on the outer ring bearing. The power supply of the pushing assembly is turned on, and the pushing assembly and the adjusting assembly form a series circuit. The rolling elements are placed on the pushing assembly by using a tool, and the pushing assembly attracts the rolling elements, forcing the rotating assembly to rotate, driving the rotating column and the supporting block to rotate, and completing the placement operation of all the rolling elements. During assembly, the lifting assembly is started to force the device to move downward until the pushing assembly is inside the outer ring bearing. Then the rotating assembly is started again to force the pushing assembly to rotate and drive the rolling elements to rotate until the rolling elements are aligned with the pockets on the cage. The driving assembly is started to force the driving assembly to generate a tendency of force, causing the transmission assembly to generate a tendency of force, forcing the pushing assembly to generate a tendency of force, and causing the pushing assembly to squeeze the rolling elements into the pockets on the cage. At this time, the rolling elements have not completely entered the pockets on the cage. The power supply of the pushing assembly and the adjusting assembly is disconnected, forcing the ejection assembly to eject, causing the ejection assembly to have an ejection effect on the rolling elements, forcing the rolling elements to generate an instantaneous force, and causing the rolling elements to completely enter the pockets on the cage, completing the assembly operation of the cylindrical rolling elements; when changing the type of the cylindrical rolling elements, since the cylindrical rolling elements have a certain weight, the weights and diameters of different types of rolling elements are different. When the diameters are different, the diameters of the bearing and the cage also change accordingly. The driving assembly is started, and the driving assembly drives the transmission assembly to rotate. Under the action of the guiding assembly, the transmission assembly is forced to drive the pushing assembly to move, causing the pushing assembly to retract or extend. When changing to a larger type of rolling element, the pushing assembly extends out of the supporting block so that the diameter of the pushing assembly is adapted to the diameter of the rolling element. At this time, the pushing assembly drives the adjusting assembly to move, forcing the resistance of the adjusting assembly to become smaller, increasing the current, increasing the attraction of the pushing assembly to the rolling elements, thereby attracting the larger type of rolling elements and preventing the rolling elements from falling. At the same time, the pushing assembly forces the ejection force of the ejection assembly to increase. According to the same steps as above, the rolling elements are aligned with the cage. Since the acting force of the ejection assembly increases, when the power supply of the pushing assembly is disconnected, the ejection assembly generates a greater ejection force, causing the rolling elements to be ejected into the pockets on the cage; in summary, a flexible assembly device for the rolling elements of a cylindrical roller bearing according to the present application can change the shape of the device itself according to the type of the rolling elements to adapt to the rolling elements, can realize the assembly of different types of rolling elements, can increase the attraction according to the size of the rolling elements, prevent the rolling elements from falling, improve the stability of the device, and can improve the ejection ability, facilitate the ejection of the rolling elements into the cage, improve the flexibility and compatibility of the device, thereby achieving the purpose of flexible assembly, improving the assembly ability of the device, improving the overall production efficiency, reducing the production cost of the enterprise, and being conducive to the market competition of the enterprise.

[0030] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present invention in a schematic way, so they only show the components related to the present invention.

[0031] Embodiment 1:

[0032] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown in the figure, a flexible assembly device for rolling elements of a cylindrical roller bearing according to the present invention includes a processing table 1. A clamping assembly 2 for clamping the outer ring bearing is arranged on the processing table 1. A support plate 3 is arranged on the processing table 1. A lifting assembly 4 is arranged on the support plate 3. The output end of the lifting assembly 4 is connected to a rotating column 5 by a bearing. A rotating assembly 6 is arranged on the rotating column 5. A support block 7 is arranged on the rotating column 5. A driving assembly 8 is arranged on the rotating column 5. A transmission assembly 9 connected to the driving assembly 8 is arranged inside the support block 7. A pushing assembly 10 connected to the transmission assembly 9 is arranged inside the support block 7. The pushing assembly 10 is used to attract the rolling elements. The pushing assembly 10 penetrates through the support block 7. A guiding assembly 11 connected to the pushing assembly 10 is arranged inside the support block 7. An adjusting assembly 12 for adjusting the resistance value is arranged on the pushing assembly 10. An ejecting assembly 13 for ejecting the rolling elements is arranged at the end of the pushing assembly 10. The ejecting assembly 13 forces the rolling elements to be ejected into the cage inside the outer ring bearing. Among them, the driving assembly 8 forces the transmission assembly 9 to move, so that the pushing assembly 10 moves out of the support block 7, so as to adapt to bearings and rolling elements of different models.

[0033] Working principle: When assembling the rolling elements, use the clamping component 2 to clamp the outer ring bearing, install the cage on the outer ring bearing, connect the power supply to the pushing component 10, form a series circuit with the pushing component 10 and the adjusting component 12, place the rolling elements on the pushing component 10 using a tool, use the pushing component 10 to attract the rolling elements, force the rotating component 6 to rotate, drive the rotating column 5 and the support block 7 to rotate, and complete the placement operation of all rolling elements. During assembly, start the lifting component 4, force the device to move downward until the pushing component 10 is inside the outer ring bearing, start the rotating component 6 again, force the pushing component 10 to rotate and drive the rolling elements to rotate until the rolling elements are aligned with the pockets on the cage, start the driving component 8, force the driving component 8 to generate a force acting trend, cause the transmission component 9 to generate a force acting trend, force the pushing component 10 to generate a force acting trend, so that the pushing component 10 squeezes the rolling elements into the pockets on the cage. At this time, the rolling elements do not completely enter the pockets on the cage. Disconnect the power supply of the pushing component 10 and the adjusting component 12, force the ejection component 13 to eject, so that the ejection component 13 produces an ejection effect on the rolling elements, force the rolling elements to generate an instantaneous acting force, and make the rolling elements completely enter the pockets on the cage, completing the assembly operation of the cylindrical rolling elements; When changing the type of the cylindrical rolling elements, since the cylindrical rolling elements have a certain weight, the weights and diameters of different types of rolling elements are different. When the diameters are different, the diameters of the bearing and the cage also change accordingly. Start the driving component 8, the driving component 8 drives the transmission component 9 to rotate, and under the action of the guiding component 11, force the transmission component 9 to drive the pushing component 10 to move, so that the pushing component 10 retracts or extends. When changing to a larger type of rolling element, make the pushing component 10 extend out of the support block 7 so that the diameter of the pushing component 10 is adapted to that of the rolling element. At this time, the pushing component 10 drives the adjusting component 12 to move, force the resistance of the adjusting component 12 to become smaller, increase the current, enhance the attraction of the pushing component 10 to the rolling elements, thereby attracting the larger type of rolling elements and preventing the rolling elements from falling. At the same time, the pushing component 10 forces the ejection force of the ejection component 13 to increase. According to the same steps above, align the rolling elements with the cage. Due to the increased acting force of the ejection component 13, when the power supply of the pushing component 10 is disconnected, the ejection component 13 generates a greater ejection acting force, so that the rolling elements are ejected into the pockets on the cage; In summary, a flexible assembly device for cylindrical roller bearing rolling elements of the present application can change the shape of the device itself according to the type of the rolling elements to adapt to the rolling elements, can achieve the assembly of different types of rolling elements, can increase the attraction according to the size of the rolling elements, prevent the rolling elements from falling, improve the stability of the device, and can improve the ejection ability, facilitate the ejection of the rolling elements into the cage, improve the flexibility and compatibility of the device, thereby achieving the purpose of flexible assembly, improving the assembly ability of the device, improving the overall production efficiency, reducing the production cost of the enterprise, and being conducive to the market competition of the enterprise.

[0043] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown in the figure, a flexible assembly device for rolling elements of a cylindrical roller bearing according to the present invention, the ejection assembly 13 includes a limiting plate 1301 arranged on the pushing block 1001. A sliding rod 1302 is arranged on the limiting plate 1301. The sliding rod 1302 penetrates through the limiting plate 1301. A magnet block 1303 adapted to the electromagnet 1003 is arranged on the sliding rod 1302. An ejection spring 1304 sleeved on the outer circle of the sliding rod 1302 is arranged between the magnet block 1303 and the limiting plate 1301.

A guiding plate 1307 is arranged on the pushing block 1001. The ejection rod 1306 penetrates through the guiding plate 1307, and an ejection head 1308 is arranged at the end of the ejection rod 1306.

[0044] Working principle: When assembling the rolling elements, start the electric push rod 201. The output end of the electric push rod 201 drives the clamping block 202 and the supporting plate 203 to move until the clamping block 202 is in mutual contact with the outer ring bearing, so as to realize clamping of the outer ring bearing by the clamping block 202, and install the cage on the outer ring bearing. The supporting plate 203 supports the edge of the outer ring bearing.

[0045] Connect the electromagnet 1003 in series to the power supply so that the electromagnet 1003 and the adjusting resistor 1203 are in series in the circuit. Use tools or an automatic conveying device to transport the rolling elements to the electromagnet 1003. Since the electromagnet 1003 is energized, the electromagnet 1003 generates an attractive force, causing the electromagnet 1003 to attract the rolling elements. Start the rotating motor 601. The output shaft of the rotating motor 601 rotates to drive the driving gear 602 to rotate. The driving gear 602 rotates to drive the rotating gear ring 603 to rotate. The rotating gear ring 603 rotates to drive the rotating column 5 to rotate. The rotating column 5 drives the support block 7 to rotate, so that the support block 7 drives the pushing block 1001 and the electromagnet 1003 to rotate, and the rolling elements are placed on different electromagnets 1003 to complete the placement operation of all rolling elements;

[0046] During assembly, start the hydraulic lifting rod 401 so that the output end of the hydraulic lifting rod 401 drives the connecting frame 402 to move downward, causing the connecting frame 402 to drive the rotating column 5, the support block 7 and the electromagnet 1003 to move downward until the support block 7 and the electromagnet 1003 are inside the outer ring bearing. Start the rotating motor 601 again. Under the action of the driving gear 602 and the rotating gear ring 603, the rotating column 5, the support block 7 and the electromagnet 1003 rotate, and the electromagnet 1003 drives the rolling elements to rotate until the rolling elements are aligned with the pockets on the cage;

[0047] Due to the contact between the rolling elements and the cage, start the driving motor 801, forcing the output shaft of the driving motor 801 not to rotate but to have a tendency to rotate, driving the driving gear 803 to have a tendency to rotate. The driving gear 803 drives the rotating gear 804 to have a tendency to rotate. The rotating gear 804 drives the rotating shaft 802 to have a tendency to rotate. The rotating shaft 802 rotates to drive the first transmission gear 901 to have a tendency to rotate, forcing the second transmission gear 902 to have a tendency to rotate, forcing the pushing straight rack 1002 to have a pushing tendency, forcing the pushing block 1001 to have a pushing tendency, causing the electromagnet 1003 to have a squeezing tendency on the rolling elements, forcing the rolling elements to be squeezed into the pockets on the cage. At this time, the rolling elements do not completely enter the pockets on the cage;

[0048] At this time, the power supply of the electromagnet 1003 is disconnected. Since the electromagnet 1003 loses its magnetism, the electromagnet 1003 releases the rolling element. However, the electromagnet 1003 exerts a squeezing effect on the rolling element. At the same time, the repulsive force of the electromagnet 1003 on the magnet block 1303 disappears instantaneously, forcing the magnet block 1303 to move closer to the electromagnet 1003. Under the action of the ejection spring 1304, the magnet block 1303 drives the sliding rod 1302 to slide instantaneously, and the sliding rod 1302 drives the connecting frame 1305 to move instantaneously. Under the action of the guide plate 1307, the connecting frame 1305 is forced to drive the ejection rod 1306 to move towards the rolling element. The ejection rod 1306 drives the ejection head 1308 to exert an instantaneous force to eject the rolling element, so that the ejection head 1308 produces an ejection effect on the rolling element, forcing the rolling element to be ejected into the pocket hole on the cage, completing the assembly operation of the cylindrical rolling element;

[0049] When replacing the type of the cylindrical rolling element, since the cylindrical rolling element has a certain weight, the weights and diameters of rolling elements of different types are different. When the diameters of the rolling elements are different, the diameters of the bearing and the cage also change accordingly. The drive motor 801 is started, and the output shaft of the drive motor 801 rotates to drive the drive gear 803 to rotate. The drive gear 803 rotates to drive the rotating gear 804 to rotate. The rotating gear 804 rotates to drive the rotating shaft 802 to rotate. The rotating shaft 802 rotates to drive the first transmission gear 901 to rotate. The first transmission gear 901 rotates to drive the second transmission gear 902 to rotate. The second transmission gear 902 rotates to drive the push straight rack 1002 to move. Under the guiding action of the guide block 1101 and the guide spring 1102, the push straight rack 1002 drives the push block 1001 to move. The push block 1001 drives the electromagnet 1003 to retract or extend, and the electromagnet 1003 drives the rolling element to move;

[0050] When replacing a larger-sized rolling element, the push block 1001 drives the electromagnet 1003 to extend out of the support block 7, so that the circle formed by the push block 1001 is adapted to the circle formed by the rolling element. At this time, the push block 1001 drives the guide block 1101 to move, the guide block 1101 drives the connecting rod 1201 to move, and the connecting rod 1201 drives the conductive ring 1202 to move on the adjusting resistor 1203, so that the resistance value of the circuit connected is reduced, thereby increasing the current, enhancing the magnetism of the electromagnet 1003, increasing the attractive force of the electromagnet 1003 on the rolling element, and the electromagnet 1003 attracts the larger-sized rolling element to prevent the rolling element from falling;

[0051] As the magnetism of the electromagnet 1003 increases, the repulsive force exerted by the electromagnet 1003 on the magnet block 1303 is forced to increase, causing the magnet block 1303 to move away from the electromagnet 1003. The magnet block 1303 drives the sliding rod 1302 to slide on the limit plate 1301, further compressing the ejection spring 1304, thereby storing more energy. The sliding rod 1302 drives the connecting frame 1305 to move away from the electromagnet 1003 or the rolling body, causing the connecting frame 1305 to drive the ejection rod 1306 and the ejection head 1308 to move away from the electromagnet 1003 or the rolling body. Since the ejection head 1308 is far from the rolling body, a greater ejection force will be generated during ejection.

[0052] According to the above assembly steps of the rolling body, after aligning the rolling body with the cage, due to the increased ejection force, when the power supply of the electromagnet 1003 is disconnected, a greater ejection force is generated by the ejection head 1308 on the rolling body, forcing the large-sized rolling body to be ejected into the pocket holes on the cage, completing the assembly operation.

[0053] On the one hand, this solution can change the shape of the device itself according to the type of the rolling body to adapt to the rolling body, and can achieve the assembly of rolling bodies of different types. On the other hand, it can increase the attraction according to the size of the rolling body to prevent the rolling body from falling and improve the stability of the device. On the third hand, it can improve the ejection ability according to the size of the rolling body, eject the rolling body into the cage, facilitating the assembly of the rolling body. Thus, it improves the flexibility and compatibility of the device, achieves the purpose of flexible assembly, improves the assembly ability of the device, improves the overall production efficiency, reduces the production cost of the enterprise, and is conducive to the market competition of the enterprise.

[0054] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
