Description

Technical Field

[0001] This invention relates to the field of combined processing technology, and in particular to an automated bearing press. Background Technology

[0002] A press is a type of forming machine that uses pressure to shape industrial products. As the name suggests, a bearing press is used to press and install bearings. In existing bearing presses, the press head structure is fixed, so it can generally only press and install bearings of a single size. When different types of bearings need to be pressed and installed, the matching bearing press head needs to be replaced. Therefore, the existing bearing press head has the defect of not being able to adapt to the pressing and installation of bearings of different sizes at the same time, resulting in low flexibility of use. Meanwhile, in the existing workpiece pressing process, not only does the bearing need to be pressed into the workpiece, but the retaining ring and oil seal also need to be pressed in separately before and after the bearing pressing. However, the existing pressing equipment can often only perform bearing pressing work alone. If retaining rings and oil seals need to be pressed in, the workpiece needs to be changed to the corresponding retaining ring press and oil seal press. The frequent changing of the workpiece between the bearing press, retaining ring press, and oil seal press will seriously affect the pressing effect of the workpiece and make the pressing efficiency of the workpiece relatively low, which cannot meet the processing needs of actual production activities. Moreover, the existing retaining ring press and oil seal press also generally have the problem of only being able to press in retaining rings and oil seals of a single size, and cannot adapt to the pressing work of retaining rings and oil seals of different sizes at the same time, which is also low in terms of usage flexibility. Summary of the Invention

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0034] Reference Figures 1-3 This invention includes an automated bearing press, comprising a press body 1, a positioning fixture 3, and a pressing unit 4. The pressing unit 4 is equipped with an upper bearing pressing head 5, an oil seal pressing head 6, and a snap ring pressing head 7. The press body 1 is the entire equipment. The pressing unit 4 performs pressing operations on the bearing, oil seal, and snap ring respectively through the upper bearing pressing head 5, the oil seal pressing head 6, and the snap ring pressing head 7. The positioning fixture 3 is used to initially limit and fix the workpiece 2 to ensure that the workpiece 2 can be pressed normally. Reference Figure 4 The upper bearing press head 5 includes a vertically arranged press rod 51, multiple sets of bearing press frames 52 distributed at the ends of the press rod 51, a drive ring 53 sleeved on the press rod 51, with the bottom surface of the drive ring 53 abutting and engaging with the top end of the bearing press frame 52, and a limiting component 54 arranged laterally on each set of bearing press frames 52. The upper bearing press head 5 is used to perform the press-fit operation of the bearing. Multiple sets of bearing press frames 52 can be arranged to form a press head for press-fitting the bearing. The limiting component 54 includes a sleeve 541 for installation, and a limiting spring 543 and a ball 542 disposed inside the sleeve 541. The outer opening of the sleeve 541 is smaller than the diameter of the ball 542. Therefore, the ball 542 can only extend outward by the elastic support of the limiting spring 543, and abuts against the inner side of the bearing by the outwardly pushed part, so as to simply limit the bearing on the upper bearing press head 5, which facilitates the subsequent press-fit operation. Reference Figure 10 The oil seal pressure head 6 includes a vertically arranged sleeve 61, a pressure rod 62 inserted into the axial position of the sleeve 61, multiple sets of protective plates 63 arranged around the end of the sleeve 61, a drive ring 64 sleeved on the sleeve 61, with the bottom surface of the drive ring 64 abutting and engaging with the top of the protective plate 63, and multiple sets of pressing components 65 arranged around the end of the pressure rod 62. The oil seal pressure head 6 is used to realize the pressing operation of the oil seal. The multiple sets of protective plates 63 can form a pressure head for pressing the oil seal. In the initial state, the oil seal is located in the cavity formed by the multiple sets of protective plates 63. Each set of protective plates 63 is equipped with an inwardly facing limiting component 66. The limiting component 66 uses the same principle as the limiting component 54 to initially limit and fix the oil seal in the oil seal pressure head 6. Reference Figure 15The snap ring press head 7 includes a vertically arranged sleeve 2 71, a pressure rod 2 72 inserted into the axial position of the sleeve 2 71, a drive disk 3 73 sleeved at the lower end of the sleeve 2 71, multiple sets of guard plates 2 74 distributed around the end of the sleeve 2 71, an inlet 75 opened on the side of the guard plate 2 74, and multiple sets of pressing components 76 distributed around the end of the pressure rod 2 72. The snap ring press head 7 is used for pressing snap rings. The multiple sets of guard plates 2 74 can form a press head for pressing snap rings 8 to be installed. Snap rings 8 to be installed can be placed into the press head composed of multiple sets of guard plates 2 74 through the inlet 75, and then the pressing rod 2 72 presses the snap rings 8 to be installed from the inside of the guard plates 2 74 into the workpiece 2.

[0035] Furthermore, refer to Figure 1 The press body 1 has a lower frame 11 below it and a pressure component 12 at the top. The pressure component 12 can provide the pressure power to push the pressing unit 4 to press downward. The side of the pressure component 12 is connected to the control panel 13, which is the control component of the whole equipment. The positioning jig 3 and the pressing unit 4 are provided with protective railings 14 to further ensure the safety of the pressing operation.

[0036] Furthermore, refer to Figure 2 The positioning fixture 3 includes a base plate 31 horizontally mounted on the press body 1, a placement platform 32 located above the base plate 31, multiple sets of support columns 33 distributed between the base plate 31 and the placement platform 32, platform lifting cylinders 34 mounted on both sides of the placement platform 32, a rotary pressing cylinder 35 mounted on the placement platform 32, a solenoid valve 36 mounted on the side of the base plate 31, a lower bearing pressure head 37 mounted at the center of the placement platform 32 (the lower bearing pressure head 37 has the same structure as the upper bearing pressure head 5), and a displacement sensor 38 mounted on the side of the base plate 31. The platform lifting cylinders 34 can adjust the overall height of the placement platform 32 by lifting and lowering, so that the positioning fixture 3 can be positioned horizontally on the press body 1. The support height of the fixture 3 can be adjusted according to the size of the workpiece 2. The rotary pressing cylinder 35 can fix the lower end of the pressing unit 4 by rotating and pressing to prevent the workpiece 2 from moving during the pressing process. The lower bearing pressing head 37 presses the bearing at the lower end of the workpiece 2 in the same way as the upper bearing pressing head 5. Since the structure of the lower bearing pressing head 37 is the same as that of the upper bearing pressing head 5, the lower bearing pressing head 37 can also perform the same operation as the upper bearing pressing head 5. The solenoid valve 36 is the control valve for controlling the operation of the platform lifting cylinder 34 and the rotary pressing cylinder 35. The displacement sensor 38 is a sensing device for detecting whether the positioning fixture 3 is installed in place.

[0037] Furthermore, refer to Figure 3The pressing unit 4 includes a base plate 41 vertically mounted on one side above the press body 1, a transverse slide rail 42 horizontally mounted on the side of the base plate 41, a mounting plate 43 horizontally slidably connected to the transverse slide rail 42, multiple sets of vertical slide rails 44 vertically mounted on the side of the mounting plate 43, and connecting blocks 45 vertically slidably connected to each set of vertical slide rails 44. Each set of connecting blocks 45 is connected to the upper bearing pressure head 5, the oil seal pressure head 6, and the snap ring pressure head 7 in a one-to-one correspondence, and is located at the top of each set of connecting blocks 45. The mounting plate 43 includes a lifting head 46, a connecting shaft 47 located above the lifting head 46, and displacement cylinders 48 and 49 respectively located on both sides of the base plate 41. The inner ends of displacement cylinders 48 and 49 are connected to both sides of the mounting plate 43. A horizontal slide rail 42 limits the mounting plate 43, allowing it to move horizontally only under the limitation of the horizontal slide rail 42. The connecting block 45 is limited by a vertical slide rail 44, allowing it to move vertically under the limitation of the vertical slide rail 44. In the vertical direction, the connecting block 45 is connected to the connecting shaft 47 through the upward-opening lifting head 46. The lower end of the connecting shaft 47 has an inverted T-shaped structure, and the opening section of the lifting head 46 is a matching T-shaped opening. Therefore, when the mounting plate 43 moves horizontally as a whole, the lower end of the connecting shaft 47 can enter the lifting head 46 from the side and form a vertical connection with the lifting head 46. The three sets of connecting blocks 45 correspond to different pressure heads. Therefore, when the mounting plate 43 moves different distances, the connecting shaft 47 can form a vertical connection with the corresponding pressure head through different lifting heads 46, thereby driving different pressure heads to perform different pressing operations. The connecting shaft 47 is connected to the pressure applying component 12 above the press body 1 and can be driven by the pressure applying component 12 to perform pressing operations on the corresponding pressure head below. The displacement cylinder 1 48 and displacement cylinder 2 49 push the mounting plate 43 to move horizontally along the transverse slide rail 42 through corresponding telescopic actions.

[0038] Furthermore, refer to Figure 3 A buffer cylinder 411 is provided on the side of the base plate 41. The buffer cylinder 411 is used to buffer the impact force when the mounting plate 43 moves on the base plate 41. Multiple displacement sensors 413 are provided below the base plate 41. The displacement sensors 413 are used to sense and detect the position change data when the mounting plate 43 moves the upper bearing pressure head 5, the oil seal pressure head 6 and the snap ring pressure head 7. A sliding groove 412 is provided on the top of the base plate 41. A pulley 431 is also provided on the mounting plate 43. The pulley 431 extends into the sliding groove 412. The two work together to further enhance the stability of the mounting plate 43 when moving on the base plate 41.

[0039] During use, refer to Figure 1The equipment is initially positioned so that the oil seal head 6 is coaxial with the workpiece 2 in the perpendicular direction. Then, the retaining ring 8, oil seal, and upper and lower bearings are installed on the retaining ring head 7, oil seal head 6, upper bearing head 5, and lower bearing head 37, respectively. The end of the pressing unit 4 is then aligned directly above the lower bearing head 37. The workpiece 2 is then fixed in place by rotating the pressing cylinder 35. The pressing of the workpiece 2 requires bearing pressing first. The displacement cylinder 48 extends, and the displacement cylinder 49 retracts. The extended displacement cylinder 48 will press the mounting plate 43 as a whole. The upper bearing pressure head 5 is pushed horizontally to the left, aligning it with the workpiece 2. At this point, the upper bearing pressure head 5, workpiece 2, and rotary clamping cylinder 35 are all on the same vertical axis. Then, the pressure applying component 12 pushes the upper bearing pressure head 5 downwards via the connecting shaft 47 and the corresponding lifting head 46. The bearings at both ends of the workpiece 2 are then pressed into their respective ends by the upper bearing pressure head 5 and the lower bearing pressure head 37. After pressing, the pressure applying component 12 moves the upper bearing pressure head 5 upwards and retracts it. Then, the displacement cylinder 1 48 retracts, and the displacement cylinder 2 49... The extension pushes the mounting plate 43 to move horizontally to the right, thereby switching the retaining ring pressure head 7 to be coaxial with the workpiece 2. Then, the pressure applying component 12 presses the retaining ring 8 to be installed into the workpiece 2 through the connecting shaft 47. After the pressing is completed, the connecting shaft 47 drives the retaining ring 8 to be installed to reset and retract. Finally, the displacement cylinder 1 48 and displacement cylinder 2 49 retract simultaneously, switching the oil seal pressure head 6 to be coaxial with the workpiece 2. Through the same operation as above, the oil seal is pressed into the workpiece 2, thereby completing the oil seal pressing operation. After the pressing is completed, the oil seal pressure head 6 resets and retracts. Finally, the rotary clamping air is released. The cylinder 35 limits the workpiece 2 and removes the workpiece 2. In summary, by combining the upper bearing pressure head 5, the oil seal pressure head 6, and the snap ring pressure head 7 on the pressing unit 4, it is only necessary to fix the workpiece on the positioning fixture 3. By adjusting the positions of the upper bearing pressure head 5, the oil seal pressure head 6, and the snap ring pressure head 7 according to the pressing requirements through the cylinders on both sides of the pressing unit 4, the pressing workpiece can be pressed to install the snap ring 8, oil seal, and bearing. No additional workpiece transfer operation is required, which ensures the pressing effect and effectively improves the efficiency of the pressing work.

[0040] Among them, reference Figure 6The pressing rod 51 includes a vertically arranged shaft 511, a limiting plate 512 at the end of the shaft 511, multiple limiting grooves 513 equally divided on the limiting plate 512, a partition 514 at the bottom of the limiting plate 512, a pressure plate 515 equally divided between the partition 514 and the limiting grooves 513, and a limiting ring 516 on the pressure plate 515. A driving ring 53 is located between the limiting plate 512 and the limiting ring 516. The bottom end of the driving ring 53 is provided with a helical rack 531. The limiting grooves 513 are used to limit the installation of limiting components 54. Under normal conditions, the multiple limiting components 54 are wrapped around the lower end of the pressing rod 51 through the limiting grooves 513. The driving ring 53 can rotate on the pressing rod 51 with its position unchanged. The limiting ring 516 is used to limit the driving ring 53.

[0041] Furthermore, refer to Figure 7 The bearing press-fit bracket 52 includes a pressing block 521 located below the pressing rod 51, a guide block 522 disposed at the top of the pressing block 521 and inserted into a limiting groove 513, and multiple sets of meshing teeth 523 formed at the top of the guide block 522 and meshing with a rack 531, a limiting piece 524 disposed at the lower end of the pressing block 521, and a limiting member 54 disposed on the limiting piece 524. The clearance groove 525 on block 521, and the pressure plate 515 inserted into the clearance groove 525, and the arc groove 526 set at the top of the limiting piece 524, and the bottom surface of the pressure plate 515 always abuts against the arc groove 526, so that the pressure plate 515 will always apply downward pressure to the bearing pressing frame 52 through the arc groove 526, ensuring the stable progress of the pressing work.

[0042] Combination Figure 8 and Figure 9During the bearing press-fitting process, multiple sets of bearing press-fitting frames 52 surround the end of the press-fitting rod 51. At this time, the diameter of the press head formed by the multiple sets of bearing press-fitting frames 52 is the bearing inner diameter 55, which is also the inner diameter of the bearing to be press-fitted. When the diameter of the bearing to be press-fitted is larger than the bearing inner diameter 55, rotating the drive ring 53 can adjust the size of the bearing inner diameter 55. The rotating drive ring 53 will push the meshing teeth 523 through the rack 531. The pushed meshing teeth 523 will push the guide block 522, which is limited by the limiting groove 513. Therefore, the guide block 522 will drive the bearing press-fitting frame 52 to move outward in the horizontal direction. The four sets of bearing press-fitting frames 52 are simultaneously driven by the drive ring 53. The pushing motion creates an outward expansion action at four equal points. The outward expansion of the four sets of bearing pressing frames 52 increases the diameter range of the pressing head from the bearing inner diameter 1 55 to the bearing inner diameter 2 56. The actual size of the bearing inner diameter 2 56 is determined by the rotation amplitude of the drive ring 1 53. Therefore, the rotation amplitude of the drive ring 1 53 can be selectively adjusted according to the actual size of the bearing, so that the bearing pressing frame 52 can initially limit and fix the large-diameter bearing. At the same time as the bearing pressing frame 52 expands, the pressing block 521 also expands synchronously. Therefore, the expanded bearing pressing frame 52 can also perform pressing operations on large-diameter bearings, so that the upper bearing pressing head 5 can realize pressing operations on bearings of different diameters, meeting more usage needs.

[0043] Among them, reference Figure 10 and Figure 11The oil seal pressure head 6 has a limiting plate 611 at its end, and a drive ring 64 is located above the limiting plate 611. A helical rack 641 is provided on the bottom surface of the drive ring 64. Multiple limiting grooves 612 are evenly spaced on the limiting plate 611. A return spring 621 is sleeved on the pressure rod 62. A spacer 623 is provided at the end of the return spring 621, and the spacer 623 is positioned within the sleeve 61. The guard plate 63 includes a positioning... Below the limiting plate 611, on the arc plate 631, there is a guide block 632 positioned above the arc plate 631. The guide block 632 is inserted into the limiting groove 612, and its top end meshes with the rack 641 for transmission. A limiting post 633 is located inside the arc plate 631. The sleeve 61, through the cooperation of the limiting groove 612 and the guide block 632, limits itself to the sleeve 61. In the initial state, multiple sets of guard plates 63 can be arranged in a ring. The pressure head structure used for pressing oil seals has the oil seal initially embedded inside the pressure head composed of multiple sets of protective plates 63. Therefore, the inner diameter of the pressure head and the diameter of the oil seal are matched. When the size of the oil seal increases, the drive ring 64 drives the rack 641 to rotate. The rack 641 will mesh with the guide block 632, pushing the protective plates 63 to move horizontally under the limitation of the limiting groove 612. The multiple sets of protective plates 63 are pushed synchronously by the drive ring 64, forming a synchronous outward expansion action. The range enclosed by the multiple sets of drive rings 64 will also increase synchronously, thereby changing the inner diameter of the pressure head composed of multiple sets of protective plates 63. According to the actual size of the oil seal, the drive ring 64 rotates by a corresponding amount, so that the expanded protective plates 63 can meet the initial embedding operation of large-diameter oil seals, and the oil seal pressure head 6 can initially perform the limiting operation of the oil seal.

[0044] Furthermore, refer to Figure 12 , Figure 13 as well as Figure 14The press-fit assembly 65 includes a press-fit block 651 located on the side of the connector 622, a connecting plate 652 located between the connector 622 and the press-fit block 651, with both ends of the connecting plate 652 extending outward into the connector 622 and the press-fit block 651, and a slot 653 formed on the outer edge of the press-fit block 651, with a limiting post 633 inserted into the slot 653. The press-fit block 651, through the cooperation of the slot 653 and the limiting post 633, can move synchronously with the guard plate 63, thus ensuring that the press-fit assembly 65 remains in contact with the inner wall of the guard plate 63. The vertical arrangement of the limiting post 633 ensures that it does not obstruct the press-fit assembly. The pressing operation is performed downwards. The connecting plate 652, located between the pressing block 651 and the connector 622, is used to ensure the connection between the pressing assembly 65 and the pressure rod 62. When the pressure rod 62 moves downwards, it pushes the pressing assembly 65 to move downwards synchronously. The pressing assembly 65, which is adjusted synchronously with the guard plate 63, can also adjust its own pressing area. Multiple pressing assemblies 65 are distributed in an equal manner, which can apply downward pressure to the oil seal from multiple directions evenly, ensuring that the oil seal can be properly pressed into the workpiece 2. Through the cooperation of the pressing assembly 65 and the guard plate 63, the oil seal pressure head 6 can realize the installation operation of oil seals of different sizes.

[0045] Among them, reference Figure 15 The end of the snap ring pressure head 7 is provided with a limiting disk 3 711, and the driving disk 3 73 is located above the limiting disk 3 711. At the same time, the bottom surface of the driving disk 3 73 is provided with a helical rack 3 732. The limiting disk 3 711 is provided with multiple sets of limiting grooves 3 712 evenly spaced. The pressure rod 2 72 is sleeved with a return spring 2 721. The end of the pressure rod 2 72 is provided with a connector 2 722. The guard plate 2 74 is inserted into the limiting groove 3 712 through the guide block 3 743. The driving disk 3 73 can rotate on the sleeve 2 71 without changing its position.

[0046] Furthermore, refer to Figure 16 The second guard plate 74 includes an upper plate 741 located below the third limiting disc 711, a lower plate 742 located at the lower end of the upper plate 741, a guide block 743 located at the top of the upper plate 741, and the top surface of the guide block 743 meshing with the third rack 732 for transmission, and a guide strip 744 located inside the upper plate 741 and the lower plate 742. The guide block 743 is limited by the third limiting groove 712 and can only slide under the limitation of the third limiting groove 712. Since the guide block 743 cooperates with the third rack 732, when the third driving disc 73 rotates, the entire second guard plate 74 can be pushed to slide through the cooperation of the third rack 732 and the guide block 743.

[0047] Furthermore, refer to Figure 17The pressing component 76 includes a pressing head 761 located inside the upper plate 741, two sets of telescopic frames 762 connected laterally and staggered inside the pressing head 761, and the telescopic frames 762 extending into the connector 722, as well as a slot 763 opened on the pressing head 761, and a guide strip 744 inserted into the slot 763. The pressing head 761 can expand outward synchronously with the guard plate 74 through the cooperation of the slot 763 and the guide strip 744. The telescopic frames 762 are used to maintain the horizontal connection between the connector 722 and the pressing head 761, ensuring that the pressure rod 72 can normally push the pressing component 76 to move vertically.

[0048] Combination Figure 16 , Figure 18 as well as Figure 19 During the use of the retaining ring press head 7, multiple sets of protective plates 74 and the pressing component 76 encircle each other to form a press head structure for pressing the retaining ring 8 to be installed. According to the actual size of the retaining ring 8 to be installed, the drive disk 73 rotates to push the multiple sets of protective plates 74 to expand horizontally in sync. The outward expansion of the multiple sets of protective plates 74 changes the inner diameter they encircle. During the expansion of the protective plates 74, the pressing component 76 expands accordingly, and the inlet 75 on the outside of the protective plates 74 also changes size synchronously, pressing the retaining ring 8 encircled by the multiple sets of protective plates 74... After adjusting the inner diameter to match the size of the retaining ring 8 to be installed, the retaining ring 8 is placed into the pressure head structure composed of multiple sets of guard plates 74 through the inlet 75. The pressure rod 72 pushes the pressing component 76 downward along the inner wall of the guard plate 74, so that the retaining ring 8 to be installed can be pressed into the workpiece 2 through the pressure head structure composed of the guard plates 74, thereby realizing the pressing operation of the retaining ring 8 to be installed. The way in which the range of the multiple sets of guard plates 74 can be adjusted according to the size of the retaining ring 8 to be installed allows the retaining ring pressure head 7 to meet the pressing operation of retaining rings 8 of different sizes.
