Description

Technical Field

[0001] The present application relates to the technical field of bearing processing, and in particular to a double-groove bearing oil filling and capping machine. Background Art

[0002] Bearings are one of the indispensable key components in modern machinery. They are mainly used to support rotating shafts or other moving parts to reduce friction and wear during movement. There are many types of bearings, including rolling bearings and sliding bearings. Rolling bearings can be further divided into ball bearings, roller bearings, etc. Among them, deep groove ball bearings are the most common type. The performance of bearings directly affects the operating efficiency, precision and life of mechanical equipment.

[0003] Double groove bearings usually refer to a special design of deep groove ball bearings, which have two grooves on the inner and outer rings of the bearings to accommodate rolling elements (usually balls). This design enables the bearings to withstand greater radial and axial loads while providing higher rotational accuracy and stability.

[0004] During the manufacturing process of bearings, an appropriate amount of grease is filled into the bearing to reduce friction and wear during bearing operation and extend the service life of the bearing. For double-groove bearings, the oil filling process needs to ensure that the grease is evenly distributed in the two grooves and does not overflow to the outside of the bearing. Then a metal or plastic cover is pressed onto the outer ring of the bearing to prevent grease leakage and prevent external contaminants from entering the bearing.

[0005] For example, a bearing quantitative oiling device with publication number CN117380475A relates to the technical field of bearing oiling equipment. The prior art includes a frame, a storage part, a transmission part and a discharge part are sequentially arranged along the feeding direction of the frame, and an oiling assembly is arranged in the middle area of ​​the transmission part; the oiling assembly includes a power shaft and a transmission sleeve; the power shaft is connected to the frame; the transmission sleeve is connected to the power shaft and can slide and displace along the axial direction, and an oil outlet is arranged below the transmission sleeve.

[0006] However, the above prior art still has some defects when injecting oil into bearings:

[0007] 1. In the above-mentioned prior art, when oiling the bearing, the oil delivery device transfers the lubricating oil from the oil inlet ring sleeve to the inside of the oil outlet channel, and then discharges it through the oil outlet piece using pressure. During the output process, the pressure is controlled to ensure the stability of the oil delivery flow rate, and combined with the oiling time, the function of quantitative oil delivery is achieved. However, what is usually used for bearing oiling is not ordinary oil, but specific grease. Grease is a semi-solid to solid lubricant composed of base oil, thickener and additives. The semi-solid or solid characteristics of grease mean that its fluidity is much lower than that of liquid lubricating oil. When oiling, the grease may not flow smoothly in the pipes and nozzles of the oiling device, which may cause uneven oiling or insufficient oiling.

[0008] 2. The above-mentioned prior art drives the transmission sleeve to move downward through the third hydraulic cylinder to drive the oil outlet part to be located in the rolling channel of the bearing, and then controls the motor to drive the transmission sleeve to rotate through the power shaft. The oil delivery equipment delivers oil to the inside, and uses the pressure oil outlet part to realize the lubricating oil application operation during the rotation process. However, the semi-solid or solid characteristics of the grease used for bearing oiling mean that its fluidity is much lower than that of liquid lubricating oil. During the process of the transmission sleeve driving the bearing to rotate and lubricate, part of the lubricating oil may overflow from the top. The overflow of grease means that the amount of grease actually applied to the bearing may be less than the expected amount, which will cause uneven lubrication of various parts of the bearing and affect the operating performance and life of the bearing.

[0009] Although the scraper can be used to drive the re-coating operation, it will still affect the oiling effect, and the overflowed grease will accumulate and adhere to the forward direction of the scraper, resulting in the overflowed grease cannot be effectively utilized, causing a waste of lubricating materials. If this continues for a long time, it will also form residues that are difficult to remove.

[0010] Based on this, and in accordance with the above-mentioned viewpoints, there is still room for improvement in the existing technology for bearing oiling. Summary of the invention

[0047] The following is combined with Figures 1 to 14 This application is described in further detail.

[0048] The embodiment of the present application discloses a double-groove bearing oil filling and capping machine, which allows lubricating oil to enter the sealing area, uses the bearing cover to push the lubricating oil into the bearing, and completes the bearing capping while filling the oil, thereby improving production efficiency.

[0049] Embodiment 1:

[0050] Reference Figure 1 and Figure 2As shown, the double groove bearing 1 usually includes an inner ring 11 and an outer ring 12, and a shaft 13 coaxial with the inner ring 11 is arranged at the center. When producing the double groove bearing 1, it is generally necessary to put the inner ring 11 into the outer ring 12 to form a raceway 14 between the inner ring 11 and the outer ring 12, and then put a suitable number of balls 15 into the raceway 14, and then rotate the inner and outer rings 12 to make the balls 15 evenly distributed in the raceway 14, and then inject lubricating oil into the raceway 14, and press the bearing cover 16 on both sides of the raceway 14 to prevent the lubricating oil from leaking.

[0051] A double groove bearing oil filling capping machine comprises a profile frame 2, two horizontal sections of the profile frame 2 are slidably penetrated by support cylinders 21, and the two support cylinders 21 are symmetrically distributed, and a capping device 3 is used for pressing the bearing cap 16.

[0052] After injecting lubricating oil into the raceway 14 of the double-groove bearing 1, the double-groove bearing 1 is transported between the two support tubes 21 through the existing transportation technology. The cover press 3 arranged in the support tube 21 will take the bearing cover 16 by adsorption. The cover press 3 arranged in the support tube 21 is used to press the bearing cover 16.

[0053] Then start the driving member 7 provided on the mold frame 2, which will drive the two support cylinders 21 to move closer to each other on the mold frame 2, and press the suction bearing cover 16 onto both sides of the raceway 14 through the cover press 3 to prevent the lubricating oil from leaking out.

[0054] Reference Figure 3 , Figure 4 and Figure 5 As shown, specifically, the capping device 3 includes an outer ring 4 arranged at the bottom of the support tube 21, and an inner ring 5 located inside the outer ring 4 is arranged at the bottom of the support tube 21. An annular capping cavity 31 is formed between the outer ring 4 and the inner ring 5. The capping cavity 31 is an annular cavity with an open lower end, which is used to accommodate the bearing cover 16.

[0055] After the lubricating oil is injected into the raceway 14, the double-groove bearing 1 is transported between the two support cylinders 21 through the existing technology, and the bearing cover 16 is placed in the lower end of the gland cavity 31 through the existing loading mechanism, and the bearing cover 16 is made to contact with a plurality of vacuum suction heads 6 circumferentially slidably arranged in the gland cavity 31. At this time, the vacuum suction pipe 32 connected to the upper end of the vacuum suction head 6 will draw air, so that a negative pressure is formed inside the vacuum suction head 6, so as to adsorb the bearing cover 16 in the gland cavity 31.

[0056] Then start the driving member 7 set on the molding frame 2. The driving member 7 will drive the two supporting cylinders 21 to move closer to each other on the molding frame 2. The supporting cylinder 21 will drive the outer ring 4 and the inner ring 5, so that the vacuum suction head 6 drives the bearing cover 16 to contact the raceway 14 of the double-groove bearing 1. At this time, the outer ring 4 will contact the outer ring 12 of the double-groove bearing 1, and the inner ring 5 will contact the inner ring 11 of the double-groove bearing 1. At the same time, the bearing cover 16 is located on the raceway 14 of the double-groove bearing 1 under the drive of the vacuum suction tube 32, and the shaft 13 will penetrate into the interior of the inner ring 5, so as not to affect the movement of the supporting cylinder 21.

[0057] A sliding disk 33 is slidably arranged inside the support tube 21, and the upper end of the vacuum suction tube 32 slides through the bottom of the support tube 21 and the sliding disk 33 in sequence. The vacuum suction tube 32 is connected to the existing vacuum negative pressure equipment to realize air extraction, so that negative pressure is formed inside the vacuum suction head 6 to adsorb the bearing cover 16 in the pressure cover cavity 31.

[0058] The vacuum suction tube 32 is provided with a limiting ring 34 located between the bottom of the support tube 21 and the sliding disk 33 . The support tube 21 is provided with a support disk 36 located above the sliding disk 33 . The support disk 36 is slidably penetrated with a push rod 37 that contacts the sliding disk 33 .

[0059] Subsequently, the driving gear 38 rotatably arranged on the support plate 36 is driven to rotate through the motor driving technology. The rotating driving gear 38 will drive the pushing rod 37 to move downward through the threaded connection with the pushing rod 37. The pushing rod 37 will abut against the sliding plate 33, causing the sliding plate 33 to move downward and push the limiting ring 34 arranged on the vacuum suction tube 32. The limiting ring 34 is located between the bottom of the support tube 21 and the sliding plate 33.

[0060] The movement of the limit ring 34 will compress the return spring 35 provided between the limit ring 34 and the bottom of the support tube 21, so that the vacuum suction tube 32 drives the vacuum suction head 6 to move downward, pressing the bearing cover 16 on both sides of the raceway 14 to prevent the lubricating oil from leaking out, and then the vacuum suction tube 32 stops drawing air from the vacuum suction head 6 to release the adsorption of the bearing cover 16.

[0061] Then, the driving gear 38 is driven to reverse through the motor driving technology. The reversed driving gear 38 will drive the pushing rod 37 to move upward through the threaded connection with the pushing rod 37. At this time, the compressed return spring 35 will push the limiting ring 34, and the sliding plate 33 will be pushed by the limiting ring 34 to make the vacuum suction tube 32 drive the vacuum suction head 6 to move upward. Since the vacuum suction tube 32 stops drawing air from the vacuum suction head 6, the upward movement of the vacuum suction head 6 will not pull the bearing cover 16, thereby preventing the bearing cover 16 from loosening.

[0062] Afterwards, the driving member 7 drives the two support cylinders 21 to move away from each other on the mold frame 2, so that the support cylinder 21 drives the outer ring 4 and the inner ring 5 back to the initial position. At the same time, the double-groove bearing 1 that has completed the pressure cap will be transported away by the existing transportation technology, and the double-groove bearing 1 that needs to be pressed will be transported between the two support cylinders 21, thus completing the pressure capping of one side of the bearing.

[0063] Afterwards, similarly, the bearing cover 16 is placed into the lower end of the gland cavity 31 through the existing loading mechanism. At this time, the vacuum suction tube 32 will draw air again to form a negative pressure inside the vacuum suction head 6 to adsorb the bearing cover 16 into the gland cavity 31, thereby carrying out the next bearing gland.

[0064] Reference Figure 6 As shown, specifically, the driving member 7 includes a driving support block 71 arranged on the supporting tube 21, and a driving shaft 73 rotatably connected to the mold frame 2 is passed through the two driving support blocks 71.

[0065] The driving shaft 73 is driven to rotate by the existing motor driving technology, and the rotating driving shaft 73 is connected with the driving support block 71 through threads, so that the driving support block 71 drives the support tube 21 to move.

[0066] When the vacuum suction head 6 absorbs the bearing cover 16 into the pressure cover cavity 31, the existing motor driving technology is used to drive the driving shaft 73 to rotate, and the rotating driving shaft 73 will drive the supporting tubes 21 to move closer to each other through the driving support block 71; conversely, when the vacuum suction tube 32 drives the vacuum suction head 6 to move downward and press the bearing cover 16 on both sides of the raceway 14, the vacuum suction tube 32 stops extracting air from the vacuum suction head 6, and then the driving shaft 73 is driven to reverse through the existing motor driving technology, and the reversed driving shaft 73 will drive the supporting tubes 21 to move away from each other through the driving support block 71.

[0067] Embodiment 2:

[0068] Reference Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 On the basis of the first embodiment, different types of double groove bearings 1 have differences in size, especially in key parameters such as the diameter and width of the inner ring 11 and the outer ring 12 and the size of the bearing cover 16, while the gland cavity 31 formed on the inner ring 5 and the outer ring 4 is always the same in size. As a result, the size difference makes it impossible for the gland cavity 31 of fixed size to effectively adapt to all types of bearings.

[0069] To solve this problem, the outer ring 4 can be changed in size to adapt to the size differences of double groove bearings 1 of different models.

[0070] Specifically, the outer ring 4 includes a plurality of circumferentially evenly distributed arc plates 41 slidingly arranged at the bottom of the support tube 21. An arc groove 42 is provided on the arc plate 41. The arc plate 41 can slide along the bottom of the support tube 21, thereby changing the diameter of the outer ring 4. An arc slide 43 is slidingly arranged between two adjacent arc grooves 42. The arc slide 43 slides relatively between two adjacent arc grooves 42, so that the arc plate 41 can move smoothly when adjusting the size of the outer ring 4.

[0071] When a larger-sized bearing needs to be adapted, the arc plate 41 will slide outward to increase the diameter of the outer ring 4 . Conversely, when a smaller-sized bearing needs to be adapted, the arc plate 41 will slide inward to reduce the diameter of the outer ring 4 .

[0072] The driving member 7 will drive the two support cylinders 21 to move closer to each other on the mold frame 2, and the support cylinder 21 will drive the outer ring 4 and the inner ring 5, so that the vacuum suction head 6 drives the bearing cover 16 to contact the raceway 14 of the double-groove bearing 1. At this time, the arc plate 41 will drive the arc guide block 44 arranged on the outer side below it, and the guide slopes 45 opened on the opposite sides of the arc guide block 44 will contact the inner side of the outer ring 12 of the double-groove bearing 1, so that the arc guide block 44 drives the arc plate 41 to move, and the arc plate 41 can slide along the bottom of the support cylinder 21 to adapt to the diameter of the outer ring 12.

[0073] Similarly, the inner ring 5 includes an annular plate 51 which is slidably arranged at the bottom of the support tube 21 and corresponds to the arc plate 41 one by one. An annular groove 52 is opened on the annular plate 51. The annular plate 51 can slide along the bottom of the support tube 21, so as to change the diameter of the inner ring 5. An annular slide 53 is slidably arranged between two adjacent annular grooves 52. The annular slide 53 slides relatively between the two adjacent annular grooves 52, so that the annular plate 51 can move smoothly when adjusting the size of the outer ring 4.

[0074] When a larger-sized bearing needs to be adapted, the annular plate 51 will slide outward to increase the diameter of the inner ring 5 . Conversely, when a smaller-sized bearing needs to be adapted, the annular plate 51 will slide inward to reduce the diameter of the inner ring 5 .

[0075] The driving member 7 will drive the two support cylinders 21 to move closer to each other on the mold frame 2, and the support cylinders 21 will drive the outer ring 4 and the inner ring 5, so that the vacuum suction head 6 drives the bearing cover 16 to contact the raceway 14 of the double groove bearing 1.

[0076] The lower ends of the annular plate 51 and the annular slide plate 53 are jointly provided with a guide slope 54 , which will abut against the inner side of the shaft 13 of the double groove bearing 1 , so that the annular plate 51 can slide along the bottom of the support tube 21 , thereby adapting to the diameter of the inner ring 11 .

[0077] The vacuum suction head 6 includes a vacuum support cover 61 slidably disposed on the arc plate 41 , and a vacuum suction cover 62 slidably disposed on the annular plate 51 and slidably connected to the vacuum support cover 61 .

[0078] When the arc plate 41 and the annular plate 51 move and change their sizes, the arc plate 41 will drive the vacuum support cover 61 to move, and the annular plate 51 will drive the vacuum suction cover 62 to move together, thereby changing the size of the capping cavity 31. The vacuum support cover 61 and the vacuum suction cover 62 will move and expand as the capping cavity 31 changes, and at the same time, the suction hole 63 jointly opened between the vacuum support cover 61 and the vacuum suction cover 62 will change accordingly.

[0079] That is, when the pressure cover cavity 31 becomes larger, the vacuum support cover 61 and the vacuum suction cover 62 move to opposite sides, and the suction hole 63 jointly opened by the two will become larger accordingly. Conversely, when the pressure cover cavity 31 becomes larger, the vacuum support cover 61 and the vacuum suction cover 62 move to opposite sides, and the suction hole 63 jointly opened by the two will become smaller accordingly.

[0080] Since the vacuum suction tube 32 is located on the vacuum suction hood 62, the annular plate 51 will drive the vacuum suction tube 32 to move together through the vacuum suction hood 62, and the vacuum suction tube 32 is connected to the suction hole 63. The vacuum suction tube 32 will draw air to form a negative pressure inside the vacuum support hood 61 and the vacuum suction hood 62, and the bearing cover 16 will be adsorbed in the pressure cover cavity 31 through the suction hole 63.

[0081] In order to ensure the movement of the vacuum suction tube 32, a sliding groove 64 corresponding to the vacuum suction tube 32 is opened at the bottom of the support tube 21, and a sliding block 65 is slidably arranged in the sliding groove 64. A sliding groove 66 corresponding to the vacuum suction tube 32 is opened on the sliding plate 33, and a sliding block 67 is slidably arranged in the sliding groove 66.

[0082] One end of the vacuum tube 32 slides through the corresponding sliding block 65 and the sliding block 67 in sequence. The movement of the vacuum tube 32 will drive the sliding block 65 and the sliding block 67 to move in the corresponding sliding groove 64 and the sliding groove 66; and the return spring 35 is located between the sliding block 65 and the limit ring 34. The movement of the vacuum tube 32 will drive the return spring 35 to move together.

[0083] Embodiment three:

[0084] Reference Figure 7 , Figure 8 and Fig. 9 On the basis of the first and second embodiments, an oil feeder 8 is provided on the outer ring 4 , and the oil feeder 8 is used to inject lubricating oil into the raceway 14 before the bearing cap 16 is pressed on both sides of the raceway 14 .

[0085] Specifically, the oil inlet 8 includes an oil inlet groove 81 located on the lower side and opened in the arc-shaped slide plate 43. An oil inlet pipe 82 connected to the oil inlet groove 81 is provided on the arc-shaped slide plate 43. The oil inlet pipe 82 is used to transport lubricating oil to the oil inlet groove 81 so that the lubricating oil enters the gland cavity 31.

[0086] When the outer ring 4 contacts the outer ring 12 of the double groove bearing 1, the inner ring 5 contacts the inner ring 11 of the double groove bearing 1, and at the same time, when the bearing cover 16 contacts the raceway 14 of the double groove bearing 1 driven by the vacuum suction tube 32, a sealing area will be formed between the inner ring 5, the outer ring 4 and the bearing cover 16 on both sides of the bearing.

[0087] At this time, the motor drive technology drives the driving gear 38 to rotate, and the rotating driving gear 38 will drive the pushing rod 37 to move downward first through the threaded connection with the pushing rod 37, and the compressed return spring 35 will push the limiting ring 34, and push the sliding disk 33 through the limiting ring 34, so that the vacuum suction tube 32 drives the vacuum suction head 6 to absorb the bearing cover 16 and move upward.

[0088] The upward movement of the bearing cover 16 will increase the size of the sealing area, forming a negative pressure in the sealing area, so that the lubricating oil is transported to the oil inlet groove 81 through the oil inlet pipe 82, and then enters the sealing area through the oil inlet groove 81. After that, the driving gear 38 is driven to reverse through the motor drive technology. The reactionary driving gear 38 will drive the pushing rod 37 to move downward through the threaded connection with the pushing rod 37. The pushing rod 37 will abut against the sliding disk 33, causing the sliding disk 33 to move downward and push the limiting ring 34 set on the vacuum suction tube 32.

[0089] The movement of the limit ring 34 will compress the return spring 35 provided between the limit ring 34 and the bottom of the support tube 21, so that the vacuum suction tube 32 drives the vacuum suction head 6 to move downward, and pushes the bearing cover 16 downward through the suction head. The bearing cover 16 will push the lubricating oil in the sealing area into the raceway 14 of the double-groove bearing 1 until the bearing cover 16 is pressed on both sides of the raceway 14 to prevent the lubricating oil from leaking out, thereby completing an oil filling and pressing cover for the double-groove bearing 1.

[0090] It should be noted that the oil inlet pipe 82 is unidirectional, that is, it can only transport lubricating oil into the gland cavity 31, thereby ensuring that when the bearing cover 16 pushes the lubricating oil into the raceway 14 of the double groove bearing 1, the lubricating oil will not flow back through the oil inlet pipe 82.

[0091] Embodiment 4:

[0092] Reference Figure 3 As shown, on the basis of the third embodiment, an adjusting member 83 is provided in the support cylinder 21, and the adjusting member 83 is used to adjust the oil inlet amount of the lubricating oil.

[0093] Specifically, the adjusting member 83 includes an adjusting ring 831 slidably disposed in the supporting tube 21 and located between the sliding plate 33 and the supporting plate 36 .

[0094] When the driving gear 38 rotates, the rotating driving gear 38 will drive the pushing rod 37 to move downward first through the threaded connection with the pushing rod 37, and the compressed return spring 35 will push the limiting ring 34, and push the sliding plate 33 through the limiting ring 34, so that the vacuum suction tube 32 drives the vacuum suction head 6 to absorb the bearing cover 16 and move upward until the sliding plate 33 contacts the adjusting ring 831, and the sliding plate 33 is restricted and stops moving. At the same time, the sliding plate 33 will limit the movement of the vacuum suction tube 32 through the limiting ring 34, so that the vacuum suction head 6 absorbs the bearing cover 16 and stops moving.

[0095] The driving gear 38 continues to drive the pushing rod 37 to move upward to the limit position, so that the pushing rod 37 is out of contact with the sliding plate 33, and then the driving gear 38 reverses. The reactionary driving gear 38 will drive the pushing rod 37 to move downward through the threaded connection with the pushing rod 37, and the pushing rod 37 will contact the sliding plate 33, so that the sliding plate 33 moves downward and pushes the limit ring 34 provided on the vacuum suction pipe 32 to compress the return spring 35, so that the vacuum suction pipe 32 drives the vacuum suction head 6 to move downward, and pushes the bearing cover 16 to move downward through the vacuum suction head 6, and this bearing cover 16 will push the lubricating oil in the sealing area into the raceway 14 of the double groove bearing 1 until the bearing cover 16 is pressed on both sides of the raceway 14 to prevent the lubricating oil from leaking, thereby completing the oil filling and pressing of the double groove bearing 1.

[0096] It can be seen from this that the amount of lubricating oil entering each time is determined by the amount of lubricating oil entering the sealing area. By rotating the adjusting screw 832 that is rotatably arranged on the supporting plate 36, the adjusting screw 832 will move through the threaded connection with the supporting plate 36. At the same time, the adjusting screw 832 drives the adjusting ring 831 to move in the supporting tube 21 through the rotational connection with the adjusting ring 831, thereby changing the position of the adjusting ring 831 to limit the sliding plate 33, thereby realizing the adjustment of the amount of lubricating oil entering.

[0097] Embodiment five:

[0098] Reference Fig.14 Based on the third and fourth embodiments, since there may be a gap between the edge of the bearing cover 16 and the gland cavity 31, the sealing effect cannot be achieved, causing the lubricating oil in the sealing area to pass through the gap, affecting the final oil intake.

[0099] To solve this problem, an airbag 9 located in the capping cavity 31 is provided between the multiple vacuum suction heads 6. The airbag 9 is located above the vacuum suction head 6. The airbag 9 can change with the change of the size of the capping cavity 31 to fill the gap in the sealing area, ensuring that the lubricating oil in the sealing area cannot pass through the gap, thereby ensuring the oil intake of the lubricating oil.

[0100] The implementation principle of the present invention is:

[0101] (1): When the double-groove bearing 1 is oiled and capped, the double-groove bearing 1 is first transported between the two support cylinders 21, and at the same time, the bearing cover 16 is placed into the lower end of the capping cavity 31 through the existing loading mechanism, and the bearing cover 16 is brought into contact with the vacuum suction head 6. At this time, the vacuum suction tube 32 will draw air to form a negative pressure inside the vacuum suction head 6, so as to adsorb the bearing cover 16 into the capping cavity 31.

[0102] (2): Then the driving member 7 will drive the two support cylinders 21 to move closer to each other on the mold frame 2, and the support cylinder 21 will drive the outer ring 4 and the inner ring 5, so that the vacuum suction head 6 drives the bearing cover 16 to contact the raceway 14 of the double-groove bearing 1. At this time, the outer ring 4 will contact the outer ring 12 of the double-groove bearing 1, and the inner ring 5 will contact the inner ring 11 of the double-groove bearing 1. At the same time, when the bearing cover 16 is located on the raceway 14 of the double-groove bearing 1 under the drive of the vacuum suction tube 32, a sealing area will be formed between the inner ring 5, the outer ring 4 and the bearing cover 16 on both sides of the bearing.

[0103] (3): The motor drive technology drives the driving gear 38 to rotate, and the rotating driving gear 38 drives the pushing rod 37 to move downward first, and the compressed return spring 35 will push the limit ring 34, and push the sliding plate 33 through the limit ring 34, so that the vacuum suction tube 32 drives the vacuum suction head 6 to absorb the bearing cover 16 and move upward. The upward movement of the bearing cover 16 will increase the size of the sealing area, so that negative pressure is formed in the sealing area, so that the lubricating oil is transported to the oil inlet groove 81 through the oil inlet pipe 82, and then enters the sealing area through the oil inlet groove 81.

[0104] (4): The driving gear 38 will drive the pushing rod 37 to move downward first through the threaded connection with the pushing rod 37, and the compressed return spring 35 will push the limit ring 34, and push the sliding plate 33 through the limit ring 34, so that the vacuum suction tube 32 drives the vacuum suction head 6 to move upward while adsorbing the bearing cover 16. The upward movement of the bearing cover 16 will increase the size of the sealing area, so that negative pressure is formed in the sealing area, so that the lubricating oil is transported to the oil inlet groove 81 through the oil inlet pipe 82, and then enters the sealing area through the oil inlet groove 81.

[0105] (5): The driving gear 38 then reverses, and the reactionary driving gear 38 drives the pushing rod 37 to move downward through the threaded connection with the pushing rod 37. The pushing rod 37 abuts against the sliding plate 33, causing the sliding plate 33 to move downward and push the limiting ring 34 set on the vacuum suction tube 32.

[0106] (6): The movement of the limit ring 34 will compress the limit return spring 35, so that the vacuum suction tube 32 drives the vacuum suction head 6 to move downward, and the suction head pushes the bearing cover 16 to move downward. The bearing cover 16 will push the lubricating oil in the sealing area into the raceway 14 of the double groove bearing 1 until the bearing cover 16 is pressed on both sides of the raceway 14 to prevent the lubricating oil from leaking out, thereby completing the oil filling and pressing of the double groove bearing 1.

[0107] (7): By rotating the adjusting screw 832 that is rotatably installed on the supporting plate 36, the adjusting screw 832 will move through the threaded connection with the supporting plate 36. At the same time, the adjusting screw 832 drives the adjusting ring 831 to move in the supporting tube 21 through the rotational connection with the adjusting ring 831, thereby changing the position of the adjusting ring 831 to limit the sliding plate 33, thereby realizing the adjustment of the oil intake amount of the lubricating oil.

[0108] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
