[0014] The present invention provides a bearing riveting machine. It has the following beneficial effects: 1. The bearing riveting machine is started by the vacuum pump and connected to the suction tube to make the fine-pore suction plate generate suction at the bottom of the power head, so that the debris produced by the processing at the bottom of the power head and adhered to the bottom of the power head are adsorbed onto the fine-pore suction plate. When the next processing is performed, when the tough rod drives the movable support rod to move upward, the fine-pore suction plate will take away the debris together, so that there is no debris at the bottom of the power head, avoiding the impact on the processing, and improving the processing quality.

[0015] 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. During the processing, the debris overflowing from the power head to the outside will be sucked into the inverted rotating cylinder by the suction pipe, and then sucked into the extraction cylinder and blocked by the filter to absorb the debris generated during the processing, so as to prevent the generated debris from participating in the riveting process again and aggravating the wear of the power head, thereby improving the processing quality.

[0016] 3. The bearing riveting machine generates a flowing airflow through the rotation of the first spiral plate, and the fine-pore suction plate loses suction at the same time. At the same time, the sweeping edge of the outer wall of the rotating cylinder sweeps the debris adsorbed by the fine-pore suction plate and allows the debris to be sucked into the inside of the rotating cylinder to clean the debris on the bearing, which can indirectly improve the processing quality.

[0017] 4. The bearing riveting machine can change the direction of the driving motor through the control panel, which will change the direction of the airflow. The airflow will push the movable plate to move, allowing the airflow to flow to the one-way channel, blowing the debris inside the extraction cylinder into the detachable collection net box for easy collection, which can indirectly improve the processing quality.

[0018] 5. The bearing riveting machine sweeps the surface of the fine-pore suction plate by sweeping the edge, and at this time the first spiral plate is rotated by the rotating cylinder through the driving motor, generating an airflow flowing to the filter screen. The gas flow rate is large and the pressure is small, thereby generating suction to suck the loose debris swept on the surface of the fine-pore suction plate into the detachable collection net box for collection together, so that the fine-pore suction plate can continuously absorb the debris generated by the processing to improve the processing quality.

[0019] 6. The bearing riveting machine, when sweeping the surface of the fine-pore suction plate while sweeping, slightly pushes the fine-pore suction plate, and the fine-pore suction plate will be reset under the action of the torsion spring and the movable support rod, and will hit the rotating cylinder, which will cause the detachable collecting net box to shake in a fixed form, so that the internal debris becomes full, increasing the space utilization rate of the detachable collecting net box, so that the detachable collecting net box can continue to work for a longer time, improving the debris collection effect, and can facilitate processing.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] Example 1: Please refer to Figure 1-8 The present invention provides a technical solution: a bearing riveting machine, comprising a riveting machine 1, a movable fixed platform 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 located inside the movable fixed platform 2, a fixed claw 3 is fixedly connected to the top of the movable fixed platform 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 platform 2, and an absorption mechanism 7 is fixedly located at the outer wall of the riveting machine 1 at a position corresponding to the adsorption mechanism 6; The adsorption mechanism 6 comprises: A tough rod 601, the tough rod 601 is fixedly connected to the outer wall of the movable fixed platform 2; A movable support rod 602, the movable support rod 602 is movably connected to the inside of the tough rod 601; The fine-pore suction plate 603 is fixedly connected to the top of the movable support rod 602. The position of the fine-pore suction plate 603 corresponds to the power head 5. The fine holes on the fine-pore suction plate 603 can absorb debris and prevent the debris from entering the fine-pore suction plate 603.

[0025] The outer wall of the tough rod 601 is fixedly connected with an air pump 607 , the outer wall of the air pump 607 is fixedly connected with a connecting suction pipe 605 , and the connecting suction pipe 605 is fixedly connected to the fine-pore suction plate 603 .

[0026] The outer wall of the movable support rod 602 is fixedly connected with a torsion spring 610, and the torsion spring 610 is fixedly connected to the tough rod 601. The outer wall of the tough rod 601 is located at the bottom of the movable support rod 602 and is fixedly connected with a first trigger block 604. The outer wall of the tough rod 601 is located at the top of the movable support rod 602 and is fixedly connected with a second trigger block 606.

[0027] An outer wall of the rotary riveting machine 1 is fixedly connected with an inclined top block 608 at a position corresponding to the tough rod 601 , and a top of the tough rod 601 is movably connected with a guide wheel 609 at the outside of the inclined top block 608 .

[0028] When in use, the bearing will be fixed at the processing position with the fixed claw 3, and the driving screw 4 will be rotated to move the movable fixed platform 2 upward, and the power head 5 will be started to work on the equipment. In the process of the movable fixed platform 2 moving upward, the inclined top block 608 will push the tough rod 601 outward under the guidance of the guide wheel 609. At the same time, the tough rod 601 will move upward with the fine-pore suction plate 603. The fine-pore suction plate 603 will be deflected at the connection with the tough rod 601 under the action of the shape of the power head 5, so that one end of the movable support rod 602 will press on the second trigger block 606, which will stop the vacuum pump 607 from working. After the processing is completed, the driving screw 4 will rotate to move the movable fixed platform 2 downward. During this process, the movable support rod 602 will be driven back to its original position by the tough rod 601, and the fine-pore suction plate 603 will be located at the bottom of the power head 5. At the same time, the movable support rod 602 will be pressed to the first trigger block 604 under the action of the tough rod 601, which will start the vacuum pump 607 to generate suction at the bottom of the power head 5 through the connected suction tube 605, so that the debris at the bottom of the power head 5 generated by the processing and adhered to the bottom of the power head 5 will be absorbed by the fine-pore suction plate 603, so that during the next processing, when the tough rod 601 drives the movable support rod 602 to move upward, the fine-pore suction plate 603 will take away the debris together, so that there is no debris at the bottom of the power head 5 to avoid affecting the processing.

[0029] Example 2: Please refer to Figure 1-4 Based on the first embodiment, the present invention provides a technical solution: The absorption mechanism 7 includes an extraction cylinder 701, which is fixedly connected to the front of the rotary riveting machine 1 at the bottom of the inclined top block 608. The extraction cylinder 701 is movably connected to a rotating cylinder 702. The bottom of the extraction cylinder 701 is fixedly connected to a one-way channel 703. The outer wall of the rotary riveting machine 1 is fixedly connected to a control panel 704.

[0030] The inner wall of the rotating cylinder 702 is fixedly connected to a connecting shaft 710 inside the extraction cylinder 701, and a driving motor 706 is fixedly connected to the back of the connecting shaft 710. The driving motor 706 is fixedly connected to the extraction cylinder 701, and a filter screen 707 is fixedly connected to the front of the driving motor 706 inside the extraction cylinder 701.

[0031] The outer wall of the rotating cylinder 702 is provided with openings, the inner wall of the rotating cylinder 702 is fixedly connected with a first spiral plate 709 , and the outer wall of the rotating cylinder 702 is fixedly connected with a sweeping edge 708 .

[0032] The outer wall of the connecting shaft 710 is fixedly connected to the second spiral plate 712, and the outer wall of the connecting shaft 710 is movably connected to the movable sheet 711 located in front of the second spiral plate 712. The one-way channel 703 is internally movably connected to two one-way movable plates 713. The inner wall of the one-way channel 703 is located at the bottom of the two one-way movable plates 713 and is fixedly connected to blocking rods 714 respectively. The bottom of the one-way channel 703 is fixedly connected to a detachable collecting net box 705. The detachable collecting net box 705 is a structure whose outer shell is composed of an air filter, which can filter and collect large-diameter debris to prevent debris from overflowing and allow airflow to pass. The blocking rod 714 can prevent the one-way movable plate 713 from falling naturally due to gravity, and help the one-way movable plate 713 to close under the push of the airflow.

[0033] A suction pipe 715 is movably connected to the front of the rotating cylinder 702 , and the suction pipe 715 is fixedly connected to the rotary riveting machine 1 , and the suction pipe 715 is located at a corresponding position of the power head 5 .

[0034] When in use, the driving motor 706 drives the connecting shaft 710 to rotate, and the connecting shaft 710 drives the second spiral plate 712 to rotate. The connecting shaft 710 drives the first spiral plate 709 to rotate through the rotating cylinder 702, which will cause the suction pipe 715 to generate suction. During processing, the debris overflowing from the power head 5 to the outside will be sucked into the inverted rotating cylinder 702 by the suction pipe 715, and then sucked into the extraction cylinder 701 and blocked by the filter 707.

[0035] During processing, the movable support rod 602 is moved upward by the tough rod 601, which will move the fine-pore suction plate 603 to the corresponding position of the rotating cylinder 702. Under the action of the torsion spring 610, the fine-pore suction plate 603 will be close to the rotating cylinder 702. When the rotating cylinder 702 rotates, the first spiral plate 709 inside will generate a flowing airflow, which will reduce the pressure inside the rotating cylinder 702 and generate suction to the outside through the opening of the rotating cylinder 702. When the fine-pore suction plate 603 moves to the position corresponding to the rotating cylinder 702, the movable support rod 602 will trigger the second trigger block 606, the vacuum pump 607 will stop working, and the fine-pore suction plate 603 will lose suction.

[0036] The control panel 704 can be used to control the change of the direction of the driving motor 706, which will change the direction of the airflow generated by the rotation of the second spiral plate 712. The airflow will push the movable plate 711 to move, and the movable plate 711 will block the port connecting the rotating cylinder 702 and the extraction cylinder 701, so that the airflow will flow to the one-way channel 703. The airflow will push open the one-way movable plate 713, and blow the debris inside the extraction cylinder 701 into the detachable collection net box 705 for easy collection. When the rotating cylinder 702 generates a moving airflow that is discharged from the filter net 707 to the outside, the air pressure inside the extraction cylinder 701 will be lower 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.

[0037] When the fine-pored suction plate 603 moves to the corresponding position of the rotating cylinder 702, the rotating cylinder 702 rotates, allowing the sweeping edge 708 to sweep the surface of the fine-pored suction plate 603. The sweeping of the sweeping edge 708 will sweep the debris attached to the surface of the fine-pored suction plate 603 to become loose, and at this time, the first spiral plate 709 is driven by the rotating cylinder 702 through the driving motor 706 to rotate, generating an air flow flowing toward the filter screen 707. The gas flow rate is large and the pressure is small, thereby generating suction to suck the loosened debris on the surface of the fine-pored suction plate 603 into the detachable collection net box 705 for collection, and the sweeping edge 708 will slightly push the fine-pored suction plate 603. After being pushed, the fine-pore suction plate 603 will reset under the action of the torsion spring 610 and the movable support rod 602, and will hit the rotating cylinder 702, which will cause the detachable collecting net box 705 to shake in a fixed form. At this time, the two one-way movable plates 713 inside the detachable collecting net box 705 are closed under the action of air pressure, so that the debris inside the detachable collecting net box 705 is not affected by the airflow, so that the shaking of the detachable collecting net box 705 will make the debris inside the detachable collecting net box 705 become substantial, which can increase the space utilization rate of the detachable collecting net box 705 and enable the detachable collecting net box 705 to continue working for a longer time.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
