A first trigger block is fixedly connected to the outer wall of the resilient rod at the bottom of the movable support rod, and a second trigger block is fixedly connected to the outer wall of the resilient rod at the top of the movable support rod.

[0013] Preferably, an inclined top block is fixedly connected to the outer wall of the riveting machine at a position corresponding to the resilient rod, and a guide wheel is movably connected to the outside of the inclined top block at the top of the resilient rod.

[0014] Preferably, the absorption mechanism includes an extraction cylinder fixedly connected to the front of the riveting machine at the bottom of the inclined top block. A rotating cylinder is movably connected inside the extraction cylinder. A one-way channel is fixedly connected to the bottom of the extraction cylinder, and a control board is fixedly connected to the outer wall of the riveting machine.

[0015] Preferably, a connecting shaft is fixedly connected to the inner wall of the rotating cylinder inside the extraction cylinder. A driving motor is fixedly connected to the back of the connecting shaft, and the driving motor is fixedly connected to the extraction cylinder. A filter screen is fixedly connected to the front of the driving motor inside the extraction cylinder.

[0016] Preferably, the outer wall of the rotating cylinder is provided with openings, a first spiral plate is fixedly connected to the inner wall of the rotating cylinder, and a sweeping edge is fixedly connected to the outer wall of the rotating cylinder.

[0017] Preferably, a second spiral plate is fixedly connected to the outer wall of the connecting shaft. A movable piece is movably connected to the front of the second spiral plate on the outer wall of the connecting shaft. Two one-way movable plates are movably connected inside the one-way channel. Blocking rods are respectively fixedly connected to the inner wall of the one-way channel at the bottoms of the two one-way movable plates. A detachable collection net box is fixedly connected to the bottom of the one-way channel.

[0018] Preferably, an inhalation pipe is movably connected to the front of the rotating cylinder, and the inhalation pipe is fixedly connected to the riveting machine and is located at a position corresponding to the power head.

[0019] The present invention provides a bearing riveting machine, which has the following beneficial effects:

[0020] 1. For this bearing riveting machine, when the air extractor is started, suction is generated at the bottom of the power head through the connecting suction pipe on the fine hole suction plate, so that the debris generated during processing and adhering to the bottom of the power head is adsorbed onto the fine hole suction plate. Thus, when the resilient rod drives the movable support rod to move upward during the next processing, the fine hole suction plate will take the debris away together, so that there is no debris at the bottom of the power head, avoiding affecting the processing and improving the processing quality.

[0021] 2. The bearing riveting machine is driven to rotate by the second spiral plate and the first spiral plate, which will generate suction in the suction pipe. When the power head is processing, the debris overflowing to the outside world will be sucked into the rotating cylinder by the suction pipe and then into the extraction cylinder, where it will be blocked by the filter screen to absorb the debris generated during processing, prevent the generated debris from participating in the riveting process again and exacerbating the wear of the power head, and improve the processing quality.

[0022] 3. The bearing riveting machine generates a flowing air current through the rotation of the first spiral plate. At the same time, the fine-hole suction plate will lose suction. At the same time, the sweeping edge on the outer wall of the rotating cylinder will sweep the debris adsorbed by the fine-hole suction plate and suck the debris into the rotating cylinder to clean the debris on the bearing, which can indirectly improve the processing quality.

[0023] 4. The bearing riveting machine can control and change the rotation direction of the drive motor through the control board, which will change the direction of the generated air current. The air current will push the movable piece to move, making the air current flow into the one-way channel, and blowing the debris inside the extraction cylinder into the detachable collection net box for easy collection, which can indirectly improve the processing quality.

[0024] 5. The bearing riveting machine sweeps the surface of the fine-hole suction plate through the sweeping edge. At this time, the first spiral plate is driven to rotate by the rotating cylinder through the drive motor, generating an air current flowing towards the filter screen. The large gas flow velocity and small pressure generate suction to suck the debris loosened by the sweeping on the surface of the fine-hole suction plate into the detachable collection net box for collection together, which can make the fine-hole suction plate continuously adsorb the debris generated during processing and improve the processing quality.

[0025] 6. When the sweeping edge sweeps the surface of the fine-hole suction plate, it slightly pushes the fine-hole suction plate. The fine-hole suction plate will reset under the action of the torsion spring and the movable support rod, and will hit the rotating cylinder. Through the fixed form, it will cause the detachable collection net box to shake, making the debris inside it more compact, increasing the space utilization rate of the detachable collection net box, enabling the detachable collection net box to work continuously for a longer time, improving the debris collection effect, and playing a role in facilitating processing.

Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0036] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] Embodiment 1: Please refer to Figures 1-8 , the present invention provides a technical solution: a bearing riveting machine, including a riveting machine 1, a movable fixed table 2 is movably connected to the front of the riveting machine 1, a driving screw 4 is movably connected to the outer wall of the riveting machine 1 inside the movable fixed table 2, a fixed claw 3 is fixedly connected to the top of the movable fixed table 2, a power head 5 is movably connected to the inside of the riveting machine 1, an adsorption mechanism 6 is fixedly connected to the outer wall of the movable fixed table 2, and an absorption mechanism 7 is fixed at a position corresponding to the adsorption mechanism 6 on the outer wall of the riveting machine 1;

[0038] The adsorption mechanism 6 includes:

[0039] The resilient rod 601 is fixedly connected to the outer wall of the movable fixed table 2;

[0040] The movable support rod 602 is movably connected inside the resilient rod 601;

[0041] The fine-hole suction plate 603 is fixedly connected to the top of the movable support rod 602. The position of the fine-hole suction plate 603 corresponds to that of the power head 5. The fine holes on the fine-hole suction plate 603 can adsorb debris while preventing the debris from entering the inside of the fine-hole suction plate 603.

[0042] An air extractor 607 is fixedly connected to the outer wall of the resilient rod 601. A connecting suction pipe 605 is fixedly connected to the outer wall of the air extractor 607, and the connecting suction pipe 605 is fixedly connected to the fine-hole suction plate 603.

[0043] A torsion spring 610 is fixedly connected to the outer wall of the movable support rod 602, and the torsion spring 610 is fixedly connected to the resilient rod 601. A first trigger block 604 is fixedly connected to the outer wall of the resilient rod 601 at the bottom of the movable support rod 602, and a second trigger block 606 is fixedly connected to the outer wall of the resilient rod 601 at the top of the movable support rod 602.

[0044] A cam 608 is fixedly connected to the outer wall of the riveting machine 1 at the position corresponding to the resilient rod 601. A guide wheel 609 is movably connected to the outside of the cam 608 at the top of the resilient rod 601.

[0045] During use, the bearing is fixed at the processing position by the fixed jaw 3, and the driving screw 4 is rotated to move the movable fixing table 2 upward. At the same time, the power head 5 is started to operate the equipment. During the upward movement of the movable fixing table 2, the inclined ejector block 608 will push the resilient rod 601 outward under the guidance of the guide wheel 609. At the same time, the resilient rod 601 will drive the microporous suction plate 603 upward. The microporous suction plate 603 will deflect at the connection with the resilient rod 601 under the action of the shape of the power head 5. In this way, one end of the movable support rod 602 will press on the second trigger block 606, which will stop the air extractor 607 from working. After the processing is completed, the driving screw 4 is rotated to move the movable fixing table 2 downward. During this process, the movable support rod 602 will be driven by the resilient rod 601 to return to its original position, and the microporous suction plate 603 will be located at the bottom of the power head 5. At the same time, under the action of the resilient rod 601, the movable support rod 602 will press on the first trigger block 604, which will start the air extractor 607 to generate suction at the bottom of the power head 5 through the connecting suction pipe 605, so that the debris generated during processing and adhering to the bottom of the power head 5 will be adsorbed onto the microporous suction plate 603. Thus, when the resilient rod 601 drives the movable support rod 602 upward during the next processing, the microporous suction plate 603 will take away the debris together, so that there is no debris at the bottom of the power head 5, avoiding affecting the processing.

[0046] Embodiment 2: Please refer to Figures 1-4 , on the basis of Embodiment 1, the present invention provides a technical solution:

[0047] The absorption mechanism 7 includes an extraction cylinder 701, which is fixedly connected to the front of the riveting machine 1 at the bottom of the inclined ejector block 608. A rotating cylinder 702 is movably connected inside the extraction cylinder 701. A one-way channel 703 is fixedly connected to the bottom of the extraction cylinder 701. A control board 704 is fixedly connected to the outer wall of the riveting machine 1.

[0048] A connecting shaft 710 is fixedly connected to the inner wall of the rotating cylinder 702 inside the extraction cylinder 701. A driving motor 706 is fixedly connected to the back of the connecting shaft 710, and the driving motor 706 is fixedly connected to the extraction cylinder 701. A filter screen 707 is fixedly connected to the front of the driving motor 706 inside the extraction cylinder 701.

[0049] Openings are provided on the outer wall of the rotating cylinder 702. A first spiral plate 709 is fixedly connected to the inner wall of the rotating cylinder 702. A sweeping edge 708 is fixedly connected to the outer wall of the rotating cylinder 702.

[0050] A second spiral plate 712 is fixedly connected to the outer wall of the connecting shaft 710. A movable piece 711 is movably connected to the outer wall of the connecting shaft 710 in front of the second spiral plate 712. Two one-way movable plates 713 are movably connected inside the one-way passage 703. Blocking rods 714 are fixedly connected to the inner wall of the one-way passage 703 at the bottoms of the two one-way movable plates 713 respectively. A detachable collection net box 705 is fixedly connected to the bottom of the one-way passage 703. The detachable collection net box 705 is a structure whose outer shell is composed of an air filter, which can filter and collect large-diameter debris, prevent the debris from overflowing, and allow the air flow to pass through. The blocking rods 714 can prevent the one-way movable plates 713 from falling naturally due to gravity, which helps the one-way movable plates 713 to close under the push of the air flow.

[0051] An inhalation pipe 715 is movably connected to the front of the rotating cylinder 702, and the inhalation pipe 715 is fixedly connected to the riveting machine 1, and the inhalation pipe 715 is located at the corresponding position of the power head 5.

[0052] During use, the drive motor 706 drives the connecting shaft 710 to rotate. The connecting shaft 710 will drive the second spiral plate 712 to rotate. Through the connecting shaft 710 passing through the rotating cylinder 702, the first spiral plate 709 will be driven to rotate, which will generate suction force in the inhalation pipe 715. When the power head 5 is processing, the debris overflowing to the outside will be sucked into the rotating cylinder 702 by the inhalation pipe 715 and then into the extraction cylinder 701 and blocked by the filter net 707.

[0053] During processing, the movable support rod 602 is driven to move upward by the resilient rod 601, which will move the fine-hole suction plate 603 to the corresponding position of the rotating cylinder 702. Under the action of the torsion spring 610, the fine-hole suction plate 603 will be close to the rotating cylinder 702. When the rotating cylinder 702 rotates, a flowing air current will be generated due to the first spiral plate 709 inside, which will reduce the pressure inside the rotating cylinder 702 and generate suction force on the outside through the openings of the rotating cylinder 702. When the fine-hole suction plate 603 moves to the corresponding position of the rotating cylinder 702, the movable support rod 602 will trigger the second trigger block 606, and the air extractor 607 will stop working, and the fine-hole suction plate 603 will lose suction force.

[0054] By controlling the control board 704, the rotation direction of the drive motor 706 can be controlled, which will cause the second spiral plate 712 to rotate and change the direction of the generated air flow. The air flow will push the movable piece 711 to move, and the movable piece 711 will block the opening where the rotating cylinder 702 communicates with the extraction cylinder 701. In this way, the air flow will flow to the one-way channel 703, and the air flow will push open the one-way movable plate 713, blowing the debris inside the extraction cylinder 701 into the detachable collection net box 705 for easy collection. When the dynamic air flow generated inside the rotating cylinder 702 is discharged outward from the filter net 707, the air pressure inside the extraction cylinder 701 will be less than the external air pressure. This air pressure will push the two one-way movable plates 713 to close to prevent the debris collected inside the detachable collection net box 705 from entering the extraction cylinder 701.

[0055] When the fine-hole suction plate 603 moves to the corresponding position of the rotating cylinder 702 and the rotating cylinder 702 rotates, the sweeping edge 708 sweeps the surface of the fine-hole suction plate 603. The sweeping of the sweeping edge 708 will loosen the debris attached to the surface of the fine-hole suction plate 603. At this time, the first spiral plate 709 is rotated by the rotating cylinder 702 driven by the drive motor 706, generating an air flow flowing towards the filter net 707. The large gas flow velocity results in a small pressure, thus generating a suction force to suck the debris loosened by the sweeping on the surface of the fine-hole suction plate 603 into the detachable collection net box 705 for combined collection. Moreover, the sweeping edge 708 will slightly push the fine-hole suction plate 603. After being pushed, the fine-hole suction plate 603 will reset under the action of the torsion spring 610 and the movable support rod 602, hitting the rotating cylinder 702. In a fixed form, it will cause the detachable collection net box 705 to shake. At this time, the two one-way movable plates 713 inside the detachable collection net box 705 are closed under the action of air pressure, so that the debris inside the detachable collection net box 705 is not affected by the air flow. Therefore, the shaking of the detachable collection net box 705 will make the debris inside the detachable collection net box 705 more compact, which can increase the space utilization rate of the detachable collection net box 705 and enable the detachable collection net box 705 to work continuously for a longer time.

[0056] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
