Description

[0002] A bearing is a mechanical component whose main function is to support a mechanical rotating body, reduce friction during its movement, and ensure its rotation accuracy.

[0003] The assembly of bearings is relatively simple, and is generally done manually. When assembling, first place the outer ring of the bearing on the workbench, and then place the inner ring inside the outer ring. At this time, the inner ring needs to be deviated from the center of the outer ring to form a larger gap between the outer ring and the inner ring. Then the ball can be placed between the outer ring and the inner ring along the gap. Finally, by pressing the inner ring in the direction of the gap, it can be automatically positioned to complete the assembly of the bearing. However, manual assembly is not suitable for large-scale bearing processing operations, and if the bearing is relatively large, the weight of the inner and outer rings will also be relatively large.

[0045] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0047] An adjustable bearing assembly and installation device provided in an embodiment of the present invention comprises a workbench 1, an outer ring fixing mechanism 2, an inner ring feeding bracket 3 and an outer ring feeding bracket 4, a loading mechanism 5, a unloading mechanism 6 and a conveyor belt 7;

[0048] The outer ring fixing mechanism 2 is as follows:

[0049] See also Figure 2 The outer ring fixing mechanism 2 includes a first mounting frame 21, the first mounting frame 21 is fixed to the lower end of the workbench 1, a first motor 22 is fixed on the first mounting frame 21, and a first driving sprocket 23 is fixed to the output end of the first motor 22;

[0050] A first positioning plate 24 is also fixed on the workbench 1, and a concentrically arranged first adjusting disk 26 is rotatably connected to the lower end of the first positioning plate 24. A plurality of first strip slideways 25 are provided on the first positioning plate 24, and a first arcuate slideway 27 corresponding to the position and number of the first strip slideways 25 is provided on the first adjusting disk 26. A concentrically arranged first driven sprocket 28 is fixed to the lower end of the first adjusting disk 26, and the first driven sprocket 28 and the first driving sprocket 23 are connected via a first transmission chain 29.

[0051] A plurality of annularly distributed clamping blocks 210 are movably mounted on the upper end of the first positioning plate 24 , and a first transmission pin 211 is vertically fixed to the lower end of the clamping block 210 . The first transmission pin 211 passes through the first strip slide 25 and extends to the inside of the first arc slide 27 .

[0052] It should be noted that: in the outer ring fixing mechanism 2, the rotation of the first motor 22 can directly drive the first active sprocket 23 to rotate, and then drive the first adjusting disk 26 to rotate through the transmission of the sprocket and the chain, and the first transmission pin 211 at the lower end of the multiple clamping blocks 210 passes through the first strip slide 25 and extends to the inside of the first arc-shaped slide 27. Therefore, when the first adjusting disk 26 rotates, it can generate a force on the first transmission pin 211 to drive each clamping block 210 to move synchronously, so as to clamp and fix the outer ring of the bearing from multiple directions.

[0053] The inner ring feeding bracket 3 is as follows:

[0054] See also Figure 3 The inner ring feeding bracket 3 includes a first support frame 31, which is fixed to the upper end of the workbench 1. A support plate 32 is fixed to the upper end of the first support frame 31. The upper part of the support plate 32 has an arc-shaped groove for placing the inner and outer rings of the bearing, and a slideway along the length direction is opened at the lowest position of the support plate 32;

[0055] A second motor 33 is also fixed on one side of the first support frame 31, and a screw rod 34 rotating on the first support frame 31 is fixed to the output end of the second motor 33, and a transmission seat 35 is threadedly connected to the screw rod 34. The transmission seat 35 passes through the slideway and extends to the inside of the groove, and is fixed with a push plate 36 that slides in the groove and is used to push the inner and outer rings of the bearing to move;

[0056] A first cylinder 37 is also fixed on one side of the first support frame 31. The first cylinder 37 is located below the support plate 32, and the output end faces upward. A baffle 38 is fixed on the output end. The baffle 38 can extend to one side of the groove and cooperate with the push plate 36 to clamp and fix the inner and outer rings of the bearing inside the groove.

[0057] Meanwhile, the outer ring feeding bracket 4 and the inner ring feeding bracket 3 have the same structure.

[0058] It should be noted that the feeding bracket is the main structure for placing the inner and outer rings of the bearings, and it has a semi-cylindrical support plate 32, so that the inner and outer rings of multiple bearings can be placed on the support plate 32; at the same time, the second motor 33 can drive the screw rod 34 to rotate, and the screw rod 34 is used to drive the transmission seat 35 and the push plate 36 to move in the axial direction. The push plate 36 contacts the inner ring or outer ring at the outermost end, so after the inner ring or outer ring at the other end is taken away, it can push the remaining inner ring or outer ring to move, so as to achieve continuous supply;

[0059] In the process of taking out the outermost inner ring or outer ring of the bearing, the first cylinder 37 is used to drive the baffle 38 to move downward. At this time, the baffle 38 has no restrictive effect on the outermost inner ring or outer ring, so it can be taken out directly. After taking it out, the baffle 38 is driven to move up to the starting position, and then the inner ring or outer ring is pushed by the push plate 36. The baffle 38 can clamp the stacked inner rings or outer rings to make them more compact and not scattered, and at the same time, it can also prevent the outermost inner ring or outer ring from falling.

[0060] The feeding mechanism 5 is as follows:

[0061] See also Figure 4 , Figure 5 and Figure 6 The feeding mechanism 5 includes a second support frame 51, which is fixed to the upper end of the workbench 1, and a third motor 52 is fixed on the second support frame 51. A fixing plate 53 is fixed to one side of the second support frame 51 through a reinforcing rod 54. The output end of the third motor 52 passes through the fixing plate 53, and a mounting plate 55 is fixed to the output end of the third motor 52. A second cylinder 56, a third cylinder 57 and a fourth cylinder 58 distributed in an annular shape are fixed to one side of the mounting plate 55. A feeding and picking member 59 is fixed to the output ends of the second cylinder 56 and the third cylinder 57, and a pressing plate 510 is fixed to the output end of the fourth cylinder 58. The pressing plate 510 is used to squeeze the inner ring of the bearing so that the inner ring of the bearing deviates from the center position of the outer ring of the bearing.

[0062] The material loading and unloading member 59 includes a second mounting frame 591, which is fixed to the output end of the second cylinder 56 or the third cylinder 57. A second positioning plate 592 is fixed on the second mounting frame 591, and a plurality of second strip slideways 593 distributed in an annular shape are provided on the second positioning plate 592.

[0063] A fourth motor 594 is also fixed to the other side of the second mounting frame 591. A second adjusting disk 595 rotating on the second mounting frame 591 is fixed to the output end of the fourth motor 594. The second adjusting disk 595 has a plurality of second arc slideways 596 distributed in an annular shape.

[0064] A plurality of annularly distributed support blocks 597 are movably mounted on one side of the second positioning plate 592 , and a second transmission pin 598 is vertically fixed to one side of the support block 597 . The second transmission pin 598 passes through the second strip slide 593 and extends to the inside of the second arc slide 596 .

[0065] It should be noted that the third motor 52 can directly drive the mounting plate 55 to rotate, so that the three groups of cylinders thereon can correspond to the first positioning plate 24 respectively;

[0066] When the material picking and loading operation is performed, the output end of the second cylinder 56 is directed toward the position of the outer ring feeding bracket 4, and the output end is extended to drive the loading and picking member 59 thereon to move until it is close to the outermost bearing outer ring. After the bearing outer ring is taken out, the mounting plate 55 is rotated to make the output end of the second cylinder 56 directed toward the position of the first positioning plate 24, so that the outer ring can be placed on the first positioning plate 24; and when the second cylinder 56 is directed toward the position of the first positioning plate 24, the output end of the third cylinder 57 is directed toward the position of the inner ring feeding bracket 3, so as to realize the picking of the inner ring, and place and fix it on the outer ring. After that, the mounting plate 55 is rotated in the opposite direction, and the inner ring of the bearing is placed on the first positioning plate 24 in the same manner; after the inner ring is also placed, the mounting plate 55 is rotated again, so that the output end of the fourth cylinder 58 faces the position of the first positioning plate 24, and then the pressing plate 510 is driven to move, and the pressing plate 510 will directly contact with the inner ring of the bearing and squeeze it. The squeezing position is one of the inner edges, and the inclined surface on the pressing plate 510 contacts with the inner ring of the bearing, so that the inner ring can be moved and offset from the center position of the outer ring, so that a gap is formed between the outer ring and the inner ring, and then the ball needs to be manually placed in the gap;

[0067] The operating mechanism of the material loading and unloading member 59 is the same as that of the outer ring fixing mechanism 2, and its support block 597 contacts the inner ring surface of the outer ring or the inner ring to achieve the fixation of the outer ring or the inner ring.

[0068] The unloading mechanism 6 is as follows:

[0069] See also Figure 7 The unloading mechanism 6 includes a third mounting frame 61, a fifth motor 62 is fixed on the third mounting frame 61, and a second driving sprocket 63 is fixed on the output end of the fifth motor 62;

[0070] A third positioning plate 64 is also rotatably connected to the workbench 1, a drum frame 65 is fixed to the lower end of the third positioning plate 64, a second driven sprocket 66 is fixed to the outer circumferential wall of the drum frame 65, and the second driven sprocket 66 is connected to the second driving sprocket 63 via a second transmission chain 67;

[0071] A fifth cylinder 68 is also fixed at the center of the lower end of the third positioning plate 64. The output end of the fifth cylinder 68 passes through the third positioning plate 64 and extends above the workbench 1. A third support frame 69 is fixed horizontally at the output end of the fifth cylinder 68. A material unloading and picking member 610 is fixed at the other end of the third support frame 69.

[0072] The material unloading and picking component 610 and the material loading and picking component 59 have the same structure.

[0073] It should be noted that after the installation of the ball bearing is completed, the inner ring of the bearing is still in an offset state. At this time, the fifth motor 62 drives the third positioning plate 64 to rotate through the sprocket and chain, and then drives the fifth cylinder 68 to rotate, so as to drive the third support frame 69 and the unloading and picking part 610 to rotate, so that the unloading and picking part 610 moves to the top of the first positioning plate 24, and then drives the unloading and picking part 610 to move downward through the fifth cylinder 68 (the structure and operation mechanism of the unloading and picking part 610 are the same as those of the loading and picking part 59), and the various support blocks included therein enter the inner ring, and then squeeze the inner ring when it is opened, firstly, the inner ring can be positioned so that it is concentric with the outer ring, so as to realize the assembly of the entire bearing, and then the entire bearing is fixed, and then the finished bearing is transferred to the conveyor belt 7, and it can be transferred out using the conveyor belt 7.

[0074] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
