Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, and in particular to an automatic bearing assembly machine. Background Art

[0002] Bearings are a common mechanical component used to support and reduce friction during rotating shafts or rolling linear motion. The most common types of rolling bearings include deep groove ball bearings, angular contact ball bearings, self-aligning tapered roller bearings, tapered roller bearings and cylindrical tapered roller bearings. The tapered rollers of tapered roller bearings are conical and arranged at an angle along the axial direction, decomposing the axial load into radial load to bear radial and axial loads. They are commonly found in heavy vehicles, industrial machinery, agricultural equipment, etc.

[0003] The structure of tapered roller bearings is relatively simple, consisting of an outer ring, an inner ring, a cage and a tapered roller. Its composition is simpler than that of common deep groove ball bearings. Most of them adopt semi-automatic assembly method. The cage is put on the tapered roller positioning table, and the tapered roller is dropped into the cage gap through the tapered roller conveying equipment. Then the inner ring is placed on the tapered roller positioning table, and the cage is lifted. The outer ring can be placed on the outside of the cage at any time. Since this method still uses manual labor, the assembly efficiency is low. Since the tapered roller is in an active state in the grooves of the cage and the tapered roller positioning table, when the inner ring is assembled, it is easy for the bottom of the inner ring to be stuck to the top of the tapered roller. Secondly, since the outer ring, inner ring, cage and tapered roller are all designed at an angle, how to realize the loading and assembly of each component is a problem that needs to be solved to achieve fully automatic assembly of tapered roller bearings.

At this time, the bottom of outer ring 01 contacts the top of outer cylinder 52, and then outer cylinder 52 drives outer ring 01 to descend, so that the top of outer ring 01 is hidden outside clamping cylinder 42, and when retainer 02 is loaded, turntable 33 drives tapered roller positioning platform 34 to move up a certain height, and then drives mechanism 6 and The positioning claws 7 place the retainer 02 on the top of the clamping cylinder 42 outside the tapered roller positioning platform 34. After the retainer 02 is adjusted in position by rotating the positioning claws 7, the turntable 33 continues to rise, so that the clamping piece 43 extends out of the top of the clamping cylinder 42, clamps the bottom circle of the retainer 02, thereby fixing the retainer 02 and aligning its axis with the working axis of the bearing assembly mechanism 2. When the tapered roller 04 is loaded, the clamping cylinder 42 drives the retainer 02 to rotate, and the turntable 33 and the tapered roller positioning platform 34 rotate synchronously with the clamping cylinder 42 to load. When the inner ring 03 is loaded, the tapered roller positioning platform 34 descends into the clamping cylinder 42, and the inner ring 03 is transferred from the top to the retainer 02 through the claw driving mechanism 6 and the positioning claws 7. Finally, the outer cylinder 52 drives the outer ring 01 to rise to complete the assembly. After the tapered roller bearing 00 is assembled, it is pushed onto the conveyor belt 12 by the finished product pusher 15.

[0035] Working principle of turntable mechanism 3 and clamping cylinder mechanism 4: motor 1 41 drives gear 1 411 to rotate, and through the meshing transmission of gear 1 411 and gear 2 421, the clamping cylinder 42 is driven to rotate, and the turntable 33 is driven to rotate through the spline groove 1 423 on the abutment plate 422 and the spline shaft 1 331, so that the clamping cylinder 42 and the tapered roller positioning platform 34 rotate synchronously. When the bottom of the turntable 33 drops to the abutment plate 422, the top surface of the tapered roller positioning platform 34 drops to the top surface of the clamping cylinder 42.

After the tops of multiple clamping members 43 extend out of the inclined groove 424 synchronously, they contact the bottom circle of the retainer 02, thereby fixing the retainer 02. After the clamping cylinder 42 descends, the clamping member 43 is reset by the spring 1 432. After resetting, the top of the clamping member 43 is lowered below the top surface of the clamping cylinder 42.

[0038] Combined with Figure 3 , Attachment Fig.10 and attached Fig.11 As shown, the claw driving mechanism 6 includes a motor 2 61, a rotating column 62 and a support arm 1 63. A gear 3 611 is provided at the output end of the motor 2 61. The rotating column 62 is rotatably arranged on the machine base 1. A gear 4 622 meshing with the gear 3 611 is provided at the bottom.

[0039] The working principle of the claw driving mechanism 6 is as follows: the motor 2 61 drives the gear 3 611 to rotate, and the gear 3 611 is meshed with the gear 4 622 to drive the rotating column 62 to rotate, and the support arm 1 63 is driven to rotate through the slide rod 623, and the cylinder 5 64 drives the support arm 1 63 to slide up and down along the slide rod 623, so that the positioning claw 7 at the end of the support arm 1 63 can move up and down and change position.

[0040] Combined with Fig.11 and attached Fig.12As shown, the positioning support claw 7 includes a motor 3 71, a swivel seat 72, a cylinder 6 73 and a plurality of arm claws 74. The motor 3 71 is arranged above the end of the support arm 63, and the swivel seat 72 is rotatably arranged below the end of the support arm 63. The output end of the motor 3 71 passes through the through hole at the end of the support arm 63 and is connected to the swivel seat 72. The cylinder 6 73 is fixed in the swivel seat 72.

When retainer 02 is loaded, positioning claw 7 is driven by claw driving mechanism 6 to move to the position of retainer 02 on waiting trough 11, and then arm claw 74 opens, and the lower end of arm claw 74 extends into the through hole of retainer 02, and the inner support The platform 742 is pressed against the inner edge of the top circle of the retainer 02. At this time, the retainer 02 can move to the top of the clamping cylinder 42 with the positioning claw 7. When the retainer 02 adjusts its position, the arm claw 74 is reset for a distance, so that the inner support platform 742 leaves the retainer 02 and the arm claw 74 is still in the through hole of the retainer 02. The rotating seat 72 rotates to make the side of the arm claw 74 contact the side of the through hole of the retainer 02, pushing the retainer 02 to rotate, so that the through hole of the retainer 02 is aligned with the concave surface of the edge of the tapered roller positioning platform 34. After the retainer 02 is fixed by the clamping member 43, the arm claw 74 is reset; When the outer ring 01 is positioned, the positioning claw 7 moves to the working axis of the bearing assembly mechanism 2, the arm claw 74 opens, and the end of the arm claw 74 contacts the inner surface of the outer ring 01. After the ends of multiple arm claws 74 contact the inner surface of the outer ring 01 at the same time, the axis of the outer ring 01 coincides with the working axis of the bearing assembly mechanism 2. When the inner ring 03 is loaded, the arm claw 74 opens first, and then moves to the position of the retainer 02 on the waiting trough 11. The arm claw 74 resets a distance so that the outer clamping platform 743 is stuck on the top edge of the inner ring 03. The inner ring 03 moves to the top of the tapered roller positioning platform 34 with the positioning claw 7, and then the arm claw 74 opens again, moves away from the inner ring 03 and resets. The inner ring 03 descends with the tapered roller positioning platform 34, and the installation is completed after the top edge of the inner ring 03 is hung on the tapered roller 04.

When rotating column 62 rotates, groove wheel 1 621 cooperates with groove wheel 2 831 through belt transmission to drive rotating drum 83 to rotate. Spline groove 2 832 inside rotating drum 83 cooperates with spline shaft 2 841 to drive rotating rod 84 to rotate. Feeding head 85 is displaced through support arm 2 842. Support arm 2 842 rotates synchronously with support arm 1 63 and rotates in the same direction. After the feeding head 85 moves to above the concave surface of the edge of the tapered roller positioning platform 34, the feeding head 85 descends to a certain position, and the tapered roller feeding device 16 (existing technology) feeds the tapered roller 04 to the feeding head 85 through the feeding pipe 86, and the tapered roller 04 freely falls along the feeding head 85 to the concave surface of the edge of the tapered roller positioning platform 34.

A spring 873 connected to the vertical plate 843 is provided on the outer side of the ejector pin 872. The output end of the cylinder 871 is connected to the ejector pin 872. The front end of the ejector pin 872 passes through the side through hole of the feed head 85, and the ejector pin 872 cooperates with the tapered roller 04 inside the feed head 85.

[0045] Working principle of limiting mechanism 87: after the feeding is completed, cylinder eight 871 pushes ejector pin 872 forward, so that the end of ejector pin 872 contacts tapered roller 04, and tapered roller 04 is pressed against the inside of feeding head 85, thereby controlling feeding head 85 not to discharge the material. When discharging the material, cylinder eight 871 is reset, and ejector pin 872 is reset by spring two 873. After tapered roller 04 is separated from ejector pin 872, it falls from the through hole of feeding head 85.

[0046] Combined with Figure 2 and attached Figure 3 As shown, the machine base 1 is symmetrically provided with a tapered roller discharging mechanism 9, which includes a cylinder 91. The cylinder 91 is arranged in the machine base 1, and a slider 92 that slides with the machine base 1 is provided at the output end of the cylinder 91. A semi-ring plate 93 is provided at the top of the slider 92 through the groove at the top of the machine base 1, and an electromagnet is provided inside the semi-ring plate 93.

[0047] Working principle of tapered roller discharging mechanism 9: After the loading of tapered roller 04 is completed, cylinder nine 91 pushes slider 92 forward, causing two semi-ring plates 93 to move toward each other until they merge into a full circle. At this time, the inner side of semi-ring plate 93 contacts retainer 02, and then the magnetic force generated by the electromagnet causes the tapered roller 04 on the inner side of retainer 02 to fit into the through hole of retainer 02 and maintain this state. Then the inner ring 03 and the tapered roller positioning platform 34 are lowered and hung on the tapered roller 04. The tapered roller positioning platform 34 descends and continues to descend to the initial position. The clamping part 43 is reset, and then the electromagnet is closed, the tapered roller discharging mechanism 9 is reset, and the outer ring 01 rises with the outer cylinder 52. After the inner surface of the outer ring 01 contacts the tapered roller 04, it will push the tapered roller 04 to move inward, and the tapered roller 04 will be stuck in the annular groove on the outer side of the inner ring 03 to complete the assembly.

[0048] In the specific implementation of the present invention, the outer ring 01 on the conveyor belt 12 is pushed onto the bearing assembly mechanism 2 through the outer ring feeder 14, and is positioned through the positioning claw 7. Then, the outer cylinder mechanism 5 drives the outer ring 01 to descend and hide in the machine base 1. The retainer 02 and the inner ring 03 are alternately placed on the material waiting trough 11 through the external transfer device. The positioning claw 7 is driven by the claw driving mechanism 6 to transfer the retainer 02 on the material waiting trough 11 to the bearing assembly mechanism 2 and adjust it. Then, the tapered roller positioning platform 34 rises, the tapered roller discharge mechanism 8 moves to the working position and then discharges the material, the turntable mechanism 3 and the clamping cylinder mechanism 4 rotate, so that the tapered roller positioning platform 34 It rotates synchronously with the retainer 02. During the rotation, the tapered roller 04 falls into the groove between the retainer 02 and the tapered roller positioning platform 34. After the tapered roller 04 is loaded, the tapered roller discharging mechanism 9 makes the tapered roller 04 close to the through hole of the retainer 02. The claw driving mechanism 6 drives the positioning claw 7 to cooperate with the turntable mechanism 3 to place the inner ring 03 on the waiting trough 11 to the inner side of the retainer 02. Then the outer cylinder mechanism 5 pushes the outer ring 01 to rise, and finally the assembly of the tapered roller bearing 00 is completed. Then the finished product pusher 15 pushes the tapered roller bearing 00 to the conveyor belt 12, and the tapered roller bearing 00 is transported to the next processing workshop.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and do not deviate from the purpose of the invention, they can creatively design a structure and embodiment similar to the technical solution, which should fall within the protection scope of the present invention.
