Description

Technical Field

[0001] This invention relates to the field of bearing assembly, and in particular to a three-piece full roll bearing for a continuous casting machine and its processing equipment. Background Technology

[0002] Bearings are key components of large equipment such as continuous casting machines, and their performance affects the stability and lifespan of the equipment. Traditional bearings consist of an inner ring, outer ring, balls, cage, and protective ring, which must be assembled in a specific order. This process is cumbersome, and errors in the assembly sequence can affect quality and increase manual complexity.

[0003] Existing assembly equipment suffers from poor adaptability, often only capable of handling bearings of fixed sizes. Replacement or adjustment is complex and inflexible, and the lack of simplified installation procedures leads to low efficiency. Furthermore, it restricts production. Some bearings require lubrication during assembly; the current process involves adding oil before installing the protective ring, which is prone to leakage due to operation or vibration, wasting lubricant and affecting lubrication effectiveness. Subsequent lubrication replenishment requires removing the protective ring, which is time-consuming, labor-intensive, and may damage components, increasing maintenance costs and downtime.

[0004] Therefore, there is an urgent need for relevant equipment to solve the above-mentioned assembly, compatibility, lubrication and maintenance problems, so as to meet the high performance requirements of continuous casting machines for bearings.

[0005] In the prior art, patent CN118951914A discloses a three-piece full complement roller bearing and processing device for continuous casting machines. The bearing body includes an inner ring, an outer ring, a cage, and needle rollers. The needle rollers are prevented from dislodging by a limiting pin in the cage engaging with a limiting hole on the needle rollers. The outer ring has a cavity with a one-way valve and an oil injection valve, utilizing Bernoulli's principle for lubrication during needle roller rotation. The processing device uses a linkage mechanism driven by a threaded rod to clamp bearings of different sizes using an arc-shaped rubber plate, and a grinding mechanism is driven by a gear and gear ring to complete the grinding. However, although this technology improves some of the original problems, there are still aspects that need further optimization to better meet actual testing requirements.

[0006] The aforementioned bearings require the installation of multiple check valves to control the overflow and contact of lubricating oil. This not only increases the number of parts and directly raises the manufacturing cost, but also damages the overall structure of the bearing's outer ring, leading to a decrease in its compressive strength and making it difficult to adapt to the high-intensity working conditions of continuous casting machines. Furthermore, the aforementioned processing device cannot simultaneously apply lubricating oil to the inside during the bearing processing, requiring an additional oil injection operation after processing, which increases the number of production steps and reduces efficiency.

[0007] Therefore, based on the above-stated viewpoints, there is still room for improvement in existing bearings and their processing equipment. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides a three-piece full roll bearing for continuous casting machines, comprising an outer ring and an inner ring, with several balls slidably mounted between the outer and inner rings. A retaining ring is mounted on the inner diameter of the outer ring, and the inner diameter of the retaining ring contacts the outer diameter of the inner ring.

[0009] The inner diameter of the inner ring, the outer diameter of the outer ring, and one side of the retaining ring are all provided with guide grooves corresponding to the outer side of the ball.

[0010] A protective ring is rotatably installed between the inner and outer rings, and a retaining component is installed on the inner diameter of the protective ring to separate the balls.

[0011] Preferably, the retaining component includes two limiting rings disposed on the side of the protective ring facing the ball, and a circular groove is formed between the limiting rings that corresponds to and contacts the ball.

[0012] The two sides of the circular groove are symmetrically fitted with plug plates located on the limit ring.

[0013] The end of the connector plate is tapered, and the end of the connector plate is inserted into one side of the corresponding ball.

[0014] Preferably, a through groove is provided on the inner diameter of the outer ring, which communicates with the guide groove, and the through groove communicates with the outer wall of the top of the outer ring.

[0015] A flap located in a through groove is hinged to the outer diameter of the protective ring by a torsion spring.

[0016] Preferably, several spline grooves are formed on the inner diameter of the inner ring.

[0017] To address the aforementioned problems, the present invention also provides a processing device for processing the aforementioned three-piece full roll bearing for continuous casting machines, comprising two cylinders respectively used to hold the inner ring, outer ring, and protective ring, mounted on a base plate, a storage unit for moving the inner ring or outer ring inside the cylinder, a support plate provided on the outer side of the cylinder, and a placement ring mounted on the side of the two support plates away from the corresponding cylinder.

[0018] The outer side of the cylinder is also equipped with a pushing assembly for pushing the inner ring, outer ring, and protective ring, which are opposite to the adjacent support plate.

[0019] A support frame is also installed on the base plate, and a pressing cylinder is installed on the support frame. The telescopic end of the pressing cylinder is rotatably equipped with a pressing end corresponding to the upper end of the placement ring.

[0020] Preferably, the storage unit includes a push spring disposed on the bottom wall of the inner cylinder, and a support block is mounted on the end of the push spring.

[0021] A bent plate is installed at the top of the cylinder, and a circular plate corresponding to the through-hole at the top of the cylinder is installed at the bend of the bent plate.

[0022] A semicircular plate is symmetrically slidably arranged inside the cylinder, and two adjusting rods are symmetrically threaded to the outside of the cylinder. The ends of the adjusting rods extend into the cylinder and are rotatably connected to the corresponding semicircular plate.

[0023] Preferably, the pushing component includes a support plate installed on the outside of the cylinder corresponding to the adjacent support plate, a sliding groove is provided on the support plate, a sliding block slides in the sliding groove, a toggle handle is rotatably installed on the sliding block, and a rotating screw threadedly connected to the sliding block is rotatably inserted on both sides of the support plate.

[0024] Preferably, a placement cylinder is installed inside the placement ring, and a clamping assembly for clamping the outer ring is installed on the placement cylinder. The clamping assembly includes several strip grooves opened at the upper end of the placement cylinder, a clamping plate sliding in the strip grooves, and a threaded disc rotatably disposed inside the placement cylinder, the threaded disc being threadedly connected to the bottom of the clamping plate.

[0025] Preferably, a drive motor is also installed in the middle of the placement cylinder. The main shaft of the drive motor rotates through the outer wall of the placement cylinder and a placement plate is fitted on it. A spline plate corresponding to the spline groove is installed on the placement plate.

[0026] Preferably, a vertical groove is provided inside the pressing end, and the two ends of the vertical groove are respectively connected to the upper and lower outer walls of the pressing end. A bending groove corresponding to the vertical groove is also provided on the outer side of the pressing end.

[0027] In summary, this application includes at least one of the following beneficial technical effects: I. This invention, by setting up a retaining ring, a protective ring, and a retaining component structure, makes the assembly sequence of each bearing component clear, reduces quality problems caused by incorrect sequence, and reduces the complexity of manual operation; the pushing component and clamping component of the processing equipment can realize the orderly pushing and precise assembly of each component, simplifying the installation process and improving assembly efficiency.

[0028] Second, the present invention allows for adjustable semicircular plate spacing via a storage unit in the processing equipment, accommodating inner rings, outer rings, and protective rings of different sizes. This enables the processing of bearings of different specifications without complex operations, enhancing the flexibility of the equipment. Simultaneously, the clamping assembly can position the outer and inner rings to the corresponding positions on the shaft, further ensuring assembly accuracy.

[0029] Third, this invention, through the design of vertical grooves and bending grooves at the pressing end, allows for simultaneous addition of lubricating oil during the ball filling process. This ensures that the lubricating oil comes into contact with the balls beforehand and enters the bearing interior with them, eliminating the need for additional oiling after processing and reducing production steps. The flap on the protective ring can be opened when adding lubricating oil without disassembling the protective ring, avoiding component damage, reducing maintenance costs and downtime, and eliminating the need for multiple valves, thus reducing the number of parts, lowering manufacturing costs, ensuring the integrity of the overall structure of the bearing outer ring, and improving compressive strength to adapt to the high-intensity working conditions of continuous casting machines.

Detailed Implementation

[0042] The following combination Figures 1 to 10 The embodiments of the present invention will be described in detail below.

[0043] This application discloses a three-piece full roll bearing for a continuous casting machine and a processing device thereof, which is applied to the assembly and operation of related components of a continuous casting machine; the protective ring and retaining components in the bearing are fixed together, requiring only one installation step during subsequent installation, thus improving efficiency; the matching processing equipment can complete the assembly of each component of the bearing separately, improving assembly efficiency and precision, and is suitable for the production and processing of this bearing.

[0044] Example 1: Refer to Figure 1 , Figure 2 and Figure 3 As shown, a three-piece full roll bearing for a continuous casting machine includes an outer ring 1, an inner ring 10, balls 11, a retaining ring 12, a guide groove 13, a protective ring 14, and a retaining assembly 2. Several balls 11 are slidably installed between the outer ring 1 and the inner ring 10. A retaining ring 12 is installed on the inner diameter of the outer ring 1, and the inner diameter of the retaining ring 12 is in contact with the outer diameter of the inner ring 10. That is, the balls 11 can roll between the outer ring 1 and the inner ring 10, and the retaining ring 12 can limit and block one side of the balls 11 to prevent the balls 11 from falling off.

[0045] The inner diameter of the inner ring 10, the outer diameter of the outer ring 1, and one side of the retaining ring 12 are all provided with a guide groove 13 corresponding to the outer side of the ball 11. The guide groove 13 can limit and guide the ball 11.

[0046] A protective ring 14 is rotatably installed between the inner ring 10 and the outer ring 1. A retaining component 2 that separates the balls 11 is installed on the inner diameter of the protective ring 14. In actual use, the outer shaft can be installed in the inner ring 10. When the outer shaft rotates, it can drive the inner ring 10 to rotate. The rotation of the inner ring 10 drives several balls 11 to rotate to reduce friction. During this process, the retaining component 2 can limit the distance between the multiple balls 11 to prevent the balls 11 from colliding. Furthermore, the protective ring 14 and the retaining ring 12 are used to prevent dust from entering the two side ports of the inner ring 10 and the outer ring 1.

[0047] Continue to refer to Figure 1 , Figure 2 and Figure 3As shown, the retaining assembly 2 is separated from the balls 11. Specifically, the retaining assembly 2 includes a limiting ring 20, a circular groove 21, a plug-in plate 22, a through groove 23, a flap 24, and a spline groove 25. The two limiting rings 20 are located on the side of the protective ring 14 facing the balls 11. A circular groove 21 is opened between the limiting rings 20, corresponding to and contacting the balls 11 one by one. Plug-in plates 22 are symmetrically installed on both sides of the circular groove 21 on the limiting rings 20. The ends of the plug-in plates 22 are tapered and plug-in... The end of the plate 22 is inserted into one side of the corresponding ball 11. That is, the insertion plate 22 is used to physically separate the ball 11 to prevent several balls 11 from colliding. The circular groove 21 is used to accommodate the upper outer side of the ball 11 and further limit the rotation of the ball 11. At this time, the two sides of the ball 11 are in contact with the guide grooves 13 on the inner ring 10 and the outer ring 1, while the upper and lower sides are in contact with the guide grooves 13 and the circular groove 21 on the retaining ring 12, thus completing the limitation of the ball 11.

[0048] Since the inner diameter of the plug plate 22 is arc-shaped and matches the outer side of the ball 11, and the plug plate 22 is stuck between several balls 11, the multiple balls 11 can also indirectly limit the protective ring 14 through the plug plate 22 and the limiting ring 20 through the gap between them, preventing it from falling off.

[0049] The inner diameter of the outer ring 1 is provided with a through groove 23 that communicates with the guide groove 13, and the through groove 23 communicates with the outer wall of the top of the outer ring 1. When installing the ball bearings 11, the ball bearings 11 can be installed one by one in the guide groove 13, that is, between the outer ring 1 and the inner ring 10, through the through groove 23.

[0050] A flap 24 located in the through groove 23 is hinged to the outer diameter of the protective ring 14 by a torsion spring. When adding lubricating oil, the flap 24 can be driven to open, and then the lubricating oil is injected into the space between the outer ring 1 and the outer ring 1 through the through groove 23. When the ball 11 rotates, the lubricating oil can come into contact with the outer side of the ball 11 through the gap between the guide groove 13 and the limit ring 20 and the circular groove 21, so as to play a smooth lubricating role.

[0051] The swing range of the flap 24 will not swing into the protective ring 14, so the swing of the flap 24 will not collide with the internal ball bearings 11, thus preventing it from flipping smoothly.

[0052] Several spline grooves 25 are provided on the inner diameter of the inner ring 10. The spline grooves 25 are used to connect with the drive key or other protrusions on the outer shaft, so that the outer shaft can smoothly drive the inner ring 10 to rotate through the spline grooves 25 when rotating.

[0053] Reference Figure 4As shown, a processing device for processing the above-mentioned three-piece full roll bearing for continuous casting machine includes a cylinder 3, a storage unit 4, a support plate 30, a placement ring 31, a pushing assembly 5, a support frame 32, a pressing cylinder 33, and a pressing end 34. The two cylinders 3 are respectively used to hold the inner ring 10, the outer ring 1, and the protective ring 14. The storage unit 4 for driving the inner ring 10 or the outer ring 1 to move inside is installed inside the cylinder 3. The support plate 30 is provided on the outside of the cylinder 3. The placement ring 31 is installed on the side of the two support plates 30 away from the corresponding cylinder 3. The pushing assembly 5 corresponding to the adjacent support plate 30 is also installed on the outside of the cylinder 3.

[0054] First, the inner ring 10 and the outer ring 1 are fitted together. Then, several fitted inner rings 10 and outer rings 1 are stacked in the corresponding cylinder 3. After that, several protective rings 14, together with the retaining components 2 on one side, are placed in the cylinder 3 and stacked. The inner ring 10 and outer ring 1 at the top of the cylinder 3 are pushed onto the corresponding support plate 30 by the pushing component 5 on one side until the pushing component 5 pushes the inner ring 10 and outer ring 1 together into the placement ring 31. Then, the ball bearing 11 is placed between the inner ring 10 and the outer ring 1.

[0055] Activate the pushing component 5 on the other side and repeat the above steps. Push the protective ring 14 into the placement ring 31 by pushing component 5, so that the protective ring 14 contacts the upper end of the inner ring 10 and the outer ring 1.

[0056] A support frame 32 is also installed on the base plate. A pressing cylinder 33 is installed on the support frame 32. The telescopic end of the pressing cylinder 33 is rotatably mounted with a pressing end 34 corresponding to the upper end of the placement ring 31. The support frame 32 is used to support the pressing cylinder 33. The pressing cylinder 33 can drive the pressing end 34 to move towards the placement ring 31 until the protective ring 14 inside the placement ring 31 is pressed onto the inner ring 10 and the outer ring 1.

[0057] Reference Figure 5 As shown, the storage unit 4 is used to drive the inner ring 10 or the outer ring 1 to move inside. Specifically, the storage unit 4 includes a push spring 40, a support block 41, a bending plate 42, a circular plate 43, a semi-circular plate 44, and an adjusting rod 45. The push spring 40 is set on the inner bottom wall of the cylinder 3. The support block 41 is installed at the end of the push spring 40. The bending plate 42 is installed at the top of the cylinder 3. The circular plate 43 corresponding to the through point at the upper end of the cylinder 3 is installed at the bend of the bending plate 42. The bending plate 42 is used to support the circular plate 43. After the parts (abbreviated as outer ring 1, inner ring 10, and protective ring 14) are stacked in the cylinder 3, the parts can be driven by the support block 41 to compress the push spring 40, so that the support block 41 moves down. Finally, the uppermost part contacts the inner bottom wall of the circular plate 43 to prevent the push spring 40 from rebounding.

[0058] A semicircular plate 44 is symmetrically slidably arranged inside the cylinder 3, and two adjusting rods 45 are symmetrically threaded to the outside of the cylinder 3. The ends of the adjusting rods 45 extend into the cylinder 3 and are rotatably connected to the corresponding semicircular plate 44. The two semicircular plates 44 can limit the outer side of the part to prevent small parts from tilting inside the cylinder 3. Similarly, depending on the size of the part, the operator can manually operate the adjusting rods 45 to rotate, so that the distance between the two semicircular plates 44 changes, thereby adapting to different part sizes.

[0059] Continue to refer to Figure 5 As shown, the pushing assembly 5 is used to push the inner ring 10, outer ring 1, and protective ring 14. Specifically, the pushing assembly 5 includes a support plate 50, a sliding groove 51, a sliding block 52, a toggle handle 53, and a rotating screw 54. The support plate 50 is installed on the outside of the cylinder 3 and corresponds to the adjacent support plate 30. The support plate 50 has a sliding groove 51, and the sliding block 52 slides in the sliding groove 51. The toggle handle 53 is rotatably installed on the sliding block 52. Rotating screws 54 that are threadedly connected to the sliding block 52 are also rotatably inserted on both sides of the support plate 50.

[0060] An external motor can be installed on one side of the support plate 50. The main shaft of the external motor is then connected to one end of the rotating screw 54, which drives the rotating screw 54 to rotate. When the rotating screw 54 rotates, it can drive the sliding block 52 to reciprocate within the sliding groove 51. The sliding block 52 can then drive the upper end of the lever handle 53 to move synchronously, so that the lever handle 53 can be in contact with the circular plate 43, i.e., the uppermost part, and push the part onto the corresponding support plate 30 until it moves into the placement ring 31. The inner diameter of the lever handle 53 is arc-shaped, which prevents the part from falling off the support plate 30 during the process of pushing the part.

[0061] After the topmost part moves out, the corresponding push spring 40 can then drive the next part to contact the inner bottom wall of the circular plate 43. An external motor can also be installed at the rotational connection between the toggle handle 53 and the sliding block 52. The external motor drives the toggle handle 53 to swing on the sliding block 52, so that when the toggle handle 53 moves to the initial position with the sliding block 52, the toggle handle 53 will not collide with the part, causing the part to be accidentally pushed away from the placement ring 31. After the toggle handle 53 moves to the initial position, the external motor can drive the toggle handle 53 back to the center position.

[0062] Reference Figure 6 , Figure 7 and Figure 8As shown, a placement cylinder 60 is installed inside the placement ring 31, and a clamping assembly 6 for clamping the outer ring 1 is installed on the placement cylinder 60. Specifically, the clamping assembly 6 includes a placement cylinder 60, a strip groove 61, a clamping plate 62, a threaded disc 63, a drive motor 64, a placement plate 65, and a splined plate 66. Several strip grooves 61 are formed at the upper end of the placement cylinder 60. The clamping plate 62 slides in the strip grooves 61, and the threaded disc 63 is rotatably arranged inside the placement cylinder 60. The threaded disc 63 is screwed to the bottom of the clamping plate 62.

[0063] When the threaded disc 63 is driven by an external force, it can rotate inside the placement cylinder 60. When it rotates, it can drive the corresponding clamping plate 62 to move in the strip groove 61. When the corresponding inner ring 10 and outer ring 1 are pushed into the placement ring 31 by the toggle handle 53, they will fall onto the placement cylinder 60. Then, the clamping plate 62 clamps and limits the outer side of the outer ring 1. At the same time, it can also push the outer ring 1 and inner ring 10 to the position corresponding to the axis of the placement cylinder 60.

[0064] A drive motor 64 is also installed in the middle of the placement cylinder 60. The main shaft of the drive motor 64 rotates through the outer wall of the placement cylinder 60 and is fitted with a placement plate 65. A spline plate 66 corresponding to the spline groove 25 is installed on the placement plate 65. That is, when the inner ring 10 and the outer ring 1 are clamped by the clamping plate 62, the inner ring 10 will contact the upper end of the placement plate 65, and the spline plate 66 can be engaged in the spline groove 25. At this time, the drive motor 64 can drive the placement plate 65 to rotate. Then, the placement plate 65 drives the inner ring 10 to rotate independently through the cooperation of the spline plate 66 and the spline groove 25. In the subsequent filling process of the ball 11, the rotation of the inner ring 10 causes the ball 11 that has just entered the guide groove 13 through the through groove 23 to be driven by the inner ring 10 to move in the guide groove 13, preventing it from blocking the subsequent ball 11, so that the ball 11 can enter the inner ring 10 and the outer ring 1 in sequence.

[0065] Reference Figure 10 As shown, it includes a vertical groove 7 and a bending groove 70. The vertical groove 7 is opened inside the pressing end 34, and the two sections of the vertical groove 7 are respectively connected to the upper and lower outer walls of the pressing end 34. The outer side of the pressing end 34 is also provided with a bending groove 70 corresponding to the vertical groove 7. The bending groove 70 is used to connect with the external ball bearing 11 filling device. That is, the external ball bearing 11 filling device can sequentially supply the ball bearing 11 into the bending groove 70. Then, the pressing cylinder 33 drives the pressing end 34 to contact the inner and outer rings 1, so that the through part at the lower end of the vertical groove 7 corresponds to the through groove 23.

[0066] Afterwards, the balls 11 in the bending groove 70 move to the vertical groove 7, and then from the vertical groove 7 to the through groove 23 until they are located between the guide grooves 13. During this period, the upper opening of the vertical groove 7 can be connected to an external lubricating oil supply device. The external lubricating oil supply device adds lubricating oil into the vertical groove 7, so that the lubricating oil can make pre-contact with the balls 11 in the vertical groove 7, and then follow the balls 11 into the space between the inner ring 10 and the outer ring 1. That is, the lubricating oil can be filled at the same time as the balls 11 are filled. This not only improves the installation efficiency of the balls 11, but also ensures that each ball 11 can make full contact with the lubricating oil, and can also use the centrifugal force generated by the rolling of the balls 11 to evenly adhere to the contact surface of the inner ring 10 and the outer ring 1, further improving the installation efficiency of the present invention.

[0067] A magnet is installed inside the pressing end 34. The inner ring 10, outer ring 1, and protective ring 14 are all made of steel. However, due to the weight of the inner ring 10 and outer ring 1, the magnet cannot attract them; it can only attract the protective ring 14. That is, after the ball bearing 11 is installed, the pushing component 5 pushes the protective ring 14 into the placement ring 31, located above the outer ring 1 and inner ring 10. At this time, the flap 24 on the outside of the protective ring 14 may not correspond to the through groove 23. Therefore, the pressing end 34 descends to attract the protective ring 14. (The text repeats itself here, so the translation stops.) An external motor is installed at the connection of cylinder 33 to drive the pressing end 34 to rotate, so that the pressing end 34 drives the flap 24 on the protective ring 14 to correspond with the through groove 23. Then the pressing end 34 pushes the protective ring 14 to keep the component 2 lowered and inserted between the inner ring 10 and the outer ring 1. During this process, the plug plate 22 will be inserted between several balls 11 to space the balls 11. At the same time, the balls 11 will also indirectly limit the protective plate through the plug plate 22. At this time, the pressing end 34 moves upward, and the protective ring 14 can be limited between the inner ring 10 and the outer ring 1.

[0068] At this point, the bearing is installed. Move the lever 53 on the drive side toward the placement ring 31 to push the bearing on the placement cylinder 60 down from above. The operator can then place a holding device to receive the finished bearing.

[0069] Example 2: Continue to refer to Figure 7 and Figure 9As shown, based on Embodiment 1, the placement cylinder 60 and the placement ring 31 are slidably connected. In order to enable the clamping plate 62 to clamp the outer ring 1, a drive assembly 8 is installed between the placement cylinder 60 and the placement ring 31. Specifically, the drive assembly 8 includes a toothed disc 80, a spiral spring 81, a drive groove 82, a drive rack 83, and a rotating shaft 84. The toothed disc 80 is rotatably disposed inside the placement cylinder 60, and a spiral spring 81 is provided between the toothed disc 80 and the threaded disc 63. That is, when the toothed disc 80 is driven by an external force, it can drive the threaded disc 63 to rotate through the spiral spring 81, so that the threaded disc 63 can indirectly drive the clamping plate 62 to clamp the outer ring 1.

[0070] A drive groove 82 is provided on the inner diameter of the placement ring 31. A drive rack 83 is installed on the inner side wall of the drive groove 82. A rotating shaft 84 is rotatably passed through the placement cylinder 60 by a torsion spring. One side of the rotating shaft 84 located inside the placement cylinder 60 meshes with the teeth at the lower end of the gear disk 80 through gear transmission. The other side of the rotating shaft 84 extends into the drive groove 82 and meshes with the drive rack 83 through gear transmission.

[0071] That is, when the pressing end 34 presses the protective ring 14 between the inner ring 10 and the outer ring 1, the placement cylinder 60 will also be lowered by the pressing force of the pressing end 34. Then, the rotating shaft 84 will rotate by meshing with the drive rack 83 through gear transmission, so that the rotating shaft 84 can drive the gear plate 80 to rotate again through gear transmission. The gear drives the threaded plate 63 to rotate through the spiral spring 81, thereby driving the clamping plate 62 to clamp the outer ring 1.

[0072] The diameters of the outer rings 1 of different specifications are different, but the downward pressure of the pressing end 34 is the same. Therefore, during the descent of the pressing end 34, when the clamping plate 62 contacts the outer side of the outer ring 1 in advance, the threaded disc 63 cannot rotate because the clamping plate 62 is limited. At this time, the toothed disc 80 will continue to drive the spiral spring 81 to rotate. That is, the spiral spring 81 stores and contracts, so that the toothed disc 80 is not affected by the clamping plate 62 being limited, and thus does not affect the entire descent stroke of the pressing end 34.

[0073] After the protective ring 14 is installed on the inner ring 10 and the outer ring 1, the pressing end 34 moves up to the initial height. At this time, the torsion spring on the outside of the rotating shaft 84 will drive the rotating shaft 84 to rotate in the opposite direction, so that the rotating shaft 84 can cooperate with the drive rack 83 through gear transmission, driving the entire placement cylinder 60 to move up to the initial position. During this process, the gear plate 80 will also be driven to rotate in the opposite direction by the rotating shaft 84. The kinetic energy of the spiral spring 81 is released, which in turn drives the threaded plate 63 to rotate in the opposite direction, so that the clamping plate 62 no longer clamps the outer ring 1, and the lever handle 53 can remove the assembled bearing from the placement cylinder 60.

[0074] During operation: First, the inner ring 10 and the outer ring 1 are put together and stacked in the corresponding cylinder 3. At the same time, several protective rings 14, together with the retaining components 2 on one side, are placed in another cylinder 3 and stacked. The parts will be compressed and pushed by the support block 41 to push the spring 40, so that the uppermost part contacts the inner bottom wall of the circular plate 43. The spacing of the semi-circular plates 44 can be adjusted by the adjusting rod 45 to accommodate different parts.

[0075] The second step is to start the push component 5 on one side. The external motor drives the rotating screw 54 to rotate, which causes the sliding block 52 to move the lever 53, pushing the inner ring 10 and outer ring 1 at the top of the cylinder 3 onto the support plate 30, until they are pushed into the placement cylinder 60 inside the placement ring 31.

[0076] Thirdly, after the inner ring 10 and outer ring 1 are placed on the placement cylinder 60, in Embodiment 1, the threaded disc 63 of the clamping assembly 6 rotates, causing the clamping plate 62 to move within the strip groove 61, clamping and limiting the outer side of the outer ring 1, and pushing it and the inner ring 10 to the corresponding position on the axis of the placement cylinder 60; in Embodiment 2, this step is not manually controlled by the threaded disc 63, and the clamping assembly 6 is not working. At the same time, the inner ring 10 contacts the placement plate 65, and the spline plate 66 is engaged in the spline groove 25.

[0077] Fourth step: Start the external ball bearing 11 loading device, supply ball bearing 11 to the vertical groove 7 of the pressing end 34 through the bending groove 70. At the same time, the external lubricating oil supply device adds lubricating oil into the vertical groove 7 so that the ball bearing 11 is in contact with the lubricating oil in advance. The pressing cylinder 33 drives the pressing end 34 to move down, so that the lower end of the vertical groove 7 corresponds to the through groove 23 of the outer ring 1. The ball bearing 11 enters the guide groove 13 between the inner ring 10 and the outer ring 1 from the vertical groove 7 through the through groove 23. During this period, the drive motor 64 drives the inner ring 10 to rotate through the spline plate 66 and the spline groove 25 to prevent the ball bearing 11 from getting blocked.

[0078] Fifth step, start the other side pushing component 5, repeat the pushing method of the second step, push the protective ring 14 into the placement ring 31, so that it is located at the upper end of the inner ring 10 and the outer ring 1; the magnet in the pressing end 34 attracts the protective ring 14, and the pressing end 34 is driven by the external motor to rotate, so that the flap 24 on the protective ring 14 corresponds to the through groove 23.

[0079] In embodiment two, the pressing end 34 presses down on the protective ring 14, causing the placement cylinder 60 to drop under pressure. The rotating shaft 84 rotates by meshing with the drive rack 83, driving the gear disc 80 to rotate. The spiral spring 81 causes the threaded disc 63 to rotate, allowing the clamping plate 62 to clamp the outer ring 1. The spiral spring 81 can adapt to different specifications of the outer ring 1. Subsequently, the pressing end 34 pushes the protective ring 14 and the retaining assembly 2 downward, allowing the insertion plate 22 to be inserted between the balls 11. After completion, the pressing end 34 moves upward, and the protective ring 14 is limited.

[0080] In the sixth step, after the pressing end 34 moves upward, in Embodiment 2, the rotating shaft 84 rotates in the opposite direction under the action of the torsion spring, causing the placement cylinder 60 to move upward. The gear plate 80 rotates in the opposite direction, causing the spiral spring 81 to release its kinetic energy. The threaded plate 63 rotates in the opposite direction, causing the clamping plate 62 to no longer clamp the outer ring 1. In Embodiment 1, the clamping plate 62 is directly de-clamped by the relevant structure. Then, the toggle handle 53 on one side moves, pushing the assembled bearing off the placement cylinder 60, where it is received by the holding device.
