DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] For example 1, please refer to Figure 1-Figure 3The present invention provides a technical solution: an automatic installation device for bearing O-rings, comprising a bottom plate 1, a connecting frame 2 fixedly connected to the top of the bottom plate 1, a top plate 3 fixedly connected to the top of the connecting frame 2, a feed tray 5 fixedly connected to the top of the top plate 3, a descending tube 4 fixedly connected to the bottom of the top plate 3, the top of the descending tube 4 being connected to the bottom of the feed tray 5, and further comprising:

[0031] The cleaning assembly 6 includes a partition plate 601, which is fixedly connected to the inner wall of the feed tray 5. A feed ring 602 is fixedly connected to the surface of the partition plate 601, and a sticking plate 603 is fixedly connected to the bottom of the feed ring 602. The sticking plate 603 has a plurality of absorption holes on its surface, and a cleaning pipe 604 is fixedly connected to the bottom of the inner wall of the sticking plate 603.

[0032] The cleaning component 6 also includes a sliding frame 605, which is fixedly connected to both sides of the partition plate 601. The inner wall of the sliding frame 605 is slidably connected to a rolling block 606. The surface of the rolling block 606 is rotatably connected to a rotating ring 607. The surface of the rotating ring 607 is fixedly connected to a contact arm 608. The contact arm 608 is made of elastic material. The inner wall of the contact arm 608 is fixedly connected to an absorption plate 609. The top of the absorption plate 609 is fixedly connected to an absorption capsule 610.

[0033] The working method of the first embodiment is as follows: first, the O-ring to be installed is placed into the feed tray 5 from the top of the feed ring 602. In the process of flowing into the feed tray 5, the O-ring will be limited by the sticking plate 603 and contact the cleaning tube 604. The cleaning tube 604 squeezes the outer surface of the O-ring to clean the dust on the surface of the O-ring from the groove hole on the surface of the cleaning tube 604 into the interior. Then, the O-ring slides from the inner wall of the feed ring 602 to the bottom through the partition plate 601, and the dust on the outer surface of the O-ring can be cleaned. When the O-ring slides inside the feed tray 5, When colliding with the absorption plate 609, the absorption plate 609 is impacted and drives the rolling block 606 to slide downward on the inner wall of the sliding frame 605. At the same time, during the sliding process, the rotating ring 607 will also rotate on the surface of the rolling block 606 due to inertia. When the rotating ring 607 rotates, the top of the contact arm 608 on its surface will swing up and down, and the absorption plate 609 will be driven to shake up and down by the swing. When the O-ring and the absorption capsule 610 squeeze each other, negative pressure suction will be generated inside the absorption plate 609. This suction will suck the dust inside the O-ring into the inside when the absorption plate 609 rotates.

[0034] Example 2: The difference from Example 1: Figure 4-Figure 5The tension component 8 includes a side plate 801 fixedly connected to both sides of the downward tube 4, the inner wall of the side plate 801 is slidably connected to a tension ring 802 through a slider, and the bottom of the inner wall of the side plate 801 is fixedly connected to an elastic ring 803. The elastic ring 803 has a telescopic reset function. One end of the elastic ring 803 away from the bottom of the inner wall of the side plate 801 contacts the surface of the tension ring 802. The end of the tension ring 802 away from the inner wall of the side plate 801 is fixedly connected to a splint 804, and the top of the splint 804 is fixedly connected to an air pressure bar 805, one end of the air pressure strip 805 away from the top of the splint 804 is fixedly connected to the bottom of the side plate 801, and a grab block 806 is rotatably connected to the top slot of the splint 804 through a rotating shaft. A snap-fit ​​groove 809 is provided at the bottom of the inner wall of the splint 804, and a compression angle 807 is fixedly connected to the bottom of the inner wall of the snap-fit ​​groove 809. An impact bag 808 is fixedly connected to the surface of the compression angle 807, and an air cavity is provided in the impact bag 808. A cleaning component 6 is provided on the surface of the feed tray 5, and a limiting component 7 is provided on the top of the bottom plate 1.

[0035] The working method of the second embodiment is as follows: first, the bearing is inserted into the interior of the placement frame 702, and the outer ring of the bearing will squeeze the surface of the compression block 704. After the compression block 704 is impacted, it shrinks inward into the pop-up box 703. After the interior of the pop-up box 703 is pressurized, air pressure is generated inside the chassis 701. The air pressure is released from the inside of the pop-up groove 705, and the air pressure drives the punching rod 706 to expand and stretch upward. After the punching rod 706 is expanded upward, it drives the clamping plate 707 to extend from the inside of the pop-up groove 705. When the clamping plate 707 extends into the interior of the bearing, the rolling ring 70 8 will rub against the inner ring of the bearing, and the clamping plate 707 and the bearing will be fixed by the rolling ring 708. When the clamping plate 707 drives the bearing to extend upward, the bearing surface will contact with the limit plate 709. The limit plates 709 on both sides of the placement frame 702 limit the bearing surface to prevent the bearing from shifting. At the same time, when in contact, the outer ring of the bearing will collide with the push plate 711, causing the push plate 711 to rotate inside the placement box 710. During rotation, the two ends of the push plate 711 will push the outer ring of the bearing, so that the bearing can accelerate to rise to the surface of the clamping plate 804.

[0036] Example 3: The difference from Example 1: Figure 6-Figure 7 The limiting assembly 7 includes a chassis 701, a placement frame 702 is fixedly connected to the top of the chassis 701, an ejection slot 705 is provided at the bottom of the inner wall of the placement frame 702, an ejection box 703 is fixedly connected to the inner wall of the placement frame 702, and a compression block 704 is slidably connected to the inner wall of the ejection box 703;

[0037] The limiting assembly 7 also includes a punching rod 706, which has a retractable characteristic. The punching rod 706 is fixedly connected to the bottom of the inner wall of the pop-up slot 705, and one end of the punching rod 706 away from the inner wall of the pop-up slot 705 is fixedly connected to a clamping plate 707. Both sides of the inner wall of the clamping plate 707 are fixedly connected to rolling rings 708, and a plurality of friction blocks are fixed on the surface of the rolling rings 708. Both sides of the placement frame 702 are fixedly connected to limiting plates 709, and the surface of the limiting plate 709 is fixedly connected to a placement box 710. Both sides of the inner wall of the placement box 710 are rotatably connected to push plates 711 through a rotating shaft.

[0038] The working method of the third embodiment is as follows: when the O-ring slides into the bottom of the feed tray 5, it will slide out to the surface of the splint 804 through the lower tube 4. When the O-ring slides into the bottom of the inner wall of the splint 804, it will collide with the compression angle 807. After being hit, the compression angle 807 will bend inward and cause pressure on the impact bag 808. At the same time, the impact bag 808 will pop out the compression angle 807 to the surface of the O-ring, and clamp the bottom of the O-ring through the compression angle 807. After the impact bag 808 is pressurized, it will generate air pressure on the splint 804. A part of the air pressure will be ejected from the slot hole at the top of the splint 804 to push the gripping block 806, so that the gripping block 806 is pressed against the splint 804. The top slot is rotated outward to the top of the O-ring, and the top of the O-ring is clamped by the grab block 806, and a part of the air pressure will flow into the bottom of the side plate 801 through the air pressure strip 805. The air pressure flows into the elastic ring 803 from the bottom of the side plate 801 to push it. The elastic ring 803 stretches upward to push the tension ring 802. After being pushed, the tension ring 802 slides upward on the inner wall of the side plate 801. When sliding upward, the tension ring 802 drives the splint 804 to pull the two sides of the O-ring apart, and the outer ring of the spring-in bearing is covered by the pulled apart O-ring. The O-ring can be installed without manpower, and there is no need to worry about the bearing not being covered in place.
