[0017] By setting up several pin feeding and pressing mechanisms to assemble several pins in batches, it can be ensured that the working rhythm of a single pin feeding and pressing mechanism is consistent with that of the other oil seal feeding mechanism, filter screen feeding mechanism, and bearing feeding mechanism.

[0018] When feeding pins, the pin feeding and pressing mechanism lifts and rotates the pallet through a lifting and rotating drive mechanism, so that two pin holes symmetrically arranged along the center of the pallet receive pins provided by the air-blowing feeding mechanism in succession. Then, the pins are assembled with the bearing housing by impact from the punch. It can simultaneously assemble the first pin with the bearing housing while feeding the second pin. At the same time, the positioning plate can provide feeding accuracy and ensure the consistency of impact force by positioning the upper surface of the positioning plate against the punch.

[0019] The bearing feeding mechanism is designed to automatically feed bearings, while the pressing component picks up the bearings by contacting the inner wall of the bearing with an elastic plunger, which reduces wear on the bearing surface. Attached Figure Description

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] like Figure 1As shown, the bearing housing assembly device for an air compressor provided in the embodiments of this application includes a frame 1, several trays 2, a conveyor line 3 disposed on the frame 1 for conveying the trays 2, and a housing loading mechanism 4 disposed at one end of the conveyor line 3. It also includes an oil seal loading mechanism 5, a filter screen loading mechanism 6, a bearing loading mechanism 7, and several pin loading and pressing mechanisms 8 sequentially disposed along one side of the conveyor line 3. The housing loading mechanism 4 is used to transfer the bearing housing 100 to the tray 2 on the conveyor line 3. The oil seal loading mechanism 5 is used to provide an oil seal 200 to the bearing housing 100 in the tray 2. The filter screen loading mechanism 6 is used to provide a filter screen 300 to the bearing housing 100 in the tray 2. The bearing loading mechanism 7 is used to provide a bearing 400 to the bearing housing 100 in the tray 2. The pin loading and pressing mechanisms 8 are used to assemble pins 500 onto the bearing housing 100 in the tray 2.

[0035] It should be noted that conveyor line 3 is a double-speed chain, which can perform non-continuous conveying according to the working rhythm of each station. This application uses a PLC control system to control the feeding mechanism, oil seal feeding mechanism 5, filter screen feeding mechanism 6, bearing feeding mechanism 7, and several pin feeding and pressing mechanisms 8. Figure 12 As shown, the bearing housing assembly includes a bearing housing 100, an oil seal 200, a filter screen 300, a bearing 400, and several pins 500.

[0036] In actual use, after receiving the bearing seat 100 transferred from the seat feeding mechanism 4 at one end of the conveyor line 3, the tray 2 is conveyed to the oil seal feeding mechanism 5. Then, the oil seal feeding mechanism 5 transfers the oil seal 200 onto the bearing seat 100. Subsequently, the conveyor line 3 conveys the tray 2 to the corresponding position of the filter screen feeding mechanism 6. Then, the filter screen feeding mechanism 6 assembles the filter screen 300 onto the bearing seat 100. Subsequently, the conveyor line 3 conveys the tray 2 along one side of the bearing feeding mechanism 7. The bearing 400 is assembled onto the bearing seat 100 by the bearing feeding mechanism 7. Then, the conveyor line 3 conveys the tray 2 to the pin feeding and pressing mechanism 8. The pin feeding and pressing mechanism 8 assembles the pin 500 into the mounting hole on the bearing seat 100.

[0037] In the above design, the entire device is highly automated and can automatically assemble the bearing 400 components.

[0038] Specifically: such as Figure 1 As shown, the seat loading mechanism 4 includes a first frame 41, a first conveyor 42 mounted on the first frame 41, a first tray 43, and a robot arm 44 mounted between the first frame 41 and the first conveyor 42. The first tray 43 is used to place the bearing seat 100, the first conveyor 42 is used to transport the first tray 43, and the robot arm 44 is used to transfer the bearing seat 100 in the first tray 43 to the tray 2.

[0039] In actual use, the bearing housing 100 is placed manually in the first tray 43, so that the first tray 43 contains multiple bearing housings 100. Then, the first line body 42 transports the first tray 43 to one end near the robot arm 44 and stops. The robot arm 44 then transfers a single bearing housing 100 to the tray 2 of the conveyor line 3.

[0040] In the above design, the structural design and specific implementation of the seat feeding mechanism 4 can realize the automatic feeding of the bearing seat 100.

[0041] Specifically: such as Figure 2 and Figure 4 As shown, the oil seal feeding mechanism 5 includes a first vibratory plate 51 mounted on the frame 1, a first linear vibrator 52 connected to the first vibratory plate 51, a first distributor 54 connected to the first linear vibrator 52, and a first transfer mechanism 53 mounted on the frame 1 for transferring the oil seals 200 in the first distributor 54. The first transfer mechanism 53 includes a first support 531 mounted on the frame 1, a first linear guide rail mounted on the first support 531 along the Y-axis, a first slide block 532 slidably mounted on the first linear guide rail, and a mechanism mounted on the first support 531 for driving the first slide block 532 along the first linear guide rail. The linear module A533 slides on linear guide rail A, linear guide rail B is vertically mounted on linear slide block 532, lifting seat 534 is slidably mounted on linear guide rail B, cylinder 535 is mounted on linear slide block 532 to drive lifting seat 534 to rise and fall, linear bearing 536 is mounted on lifting seat 534, lifting shaft 537 is sleeved in linear bearing 536, pressure sensor 538 is mounted on the upper end face of lifting shaft 537, suction nozzle 539 is mounted on the lower end of lifting shaft 537, and limiting post 530 is radially mounted on lifting shaft 537.

[0042] In actual use, the oil seal 200 is vibrated onto the straight vibrator by the first vibrating plate 51. Then the oil seal 200 is conveyed to the first distributor 54 along the straight vibrator. After receiving one oil seal 200, the first distributor 54 blocks the end of the straight vibrator. Then the first transfer mechanism 53 transfers the oil seal 200 from the first distributor 54 to the bearing seat 100 in the tray 2. The rotation of the first transfer mechanism 53 is as follows: the first linear module A533 drives the first slide 532 to slide along the first linear guide rail A to above the first distributor 54. Then, the first cylinder 535 drives the first lifting seat 534 to move downward, causing the first lifting seat 534 to drive the lifting shaft 537 and the suction nozzle to move downward. The first suction nozzle 539 picks up the oil seal 200 from the first distributor 54. Then, the first cylinder 535 drives the first lifting seat 534 to rise, and the first linear module A533 drives the first slide 532 to move along the first linear guide rail A. The cylinder moves to the bearing seat 100 above the tray 2. Then, the first cylinder 535 drives the first lifting seat 534 to move down. The suction nozzle drives the oil seal 200 to be assembled on the bearing seat 100. Before the oil seal 200 is fully assembled, the stroke of the first cylinder 535 is not yet completed after the oil seal 200 contacts the bearing seat 100. The lifting shaft 537 will move up relative to the first linear bearing 536 and abut against the pressure sensor 538. When the pressure value of the pressure sensor 538 reaches the preset value, the first cylinder 535 stops driving, and the assembly of the oil seal 200 and the bearing seat 100 is completed.

[0043] In the above design, the structural design and specific implementation of the oil seal feeding mechanism 5 can effectively realize the assembly of the oil seal 200 and the bearing seat 100.

[0044] Specifically: such as Figure 2 and Figure 3 As shown, the first feeder 54 includes a mounting base 541 mounted on the frame 1, a slide cylinder 542 mounted on the mounting base 541 along the X-axis, a receiving seat 543 mounted on the slide cylinder 542, and an optical fiber sensor 544 mounted on the receiving seat 543. The receiving seat 543 is provided with a receiving groove that docks with the first vibrator 52.

[0045] In actual use, the slide cylinder 542 drives the receiving seat 543 to move to correspond with the discharge port of the first vibrator 52, so that the oil seal 200 enters the receiving groove of the receiving seat 543 along the first vibrator 52. When the light sensor detects that there is an oil seal 200 in the receiving groove, the PLC control system controls the slide cylinder 542 to drive the receiving seat 543 to move along the X-axis, so that the receiving groove is misaligned with the discharge port of the first vibrator 52, thereby blocking the discharge port of the first vibrator 52.

[0046] In the above design, the structural design and specific implementation of the first distributor 54 enable it to receive the oil seal 200 flowing out of the first vibrator 52.

[0047] Specifically: such as Figure 5 and Figure 6 As shown, the filter screen feeding mechanism 6 includes a second vibratory plate 61 mounted on the frame 1, a second linear vibrator 62 connected to the second vibratory plate 61, a second distributor 63 mounted on the frame 1 and connected to the second linear vibrator 62, and a second transfer mechanism 64 mounted on the frame 1. The second transfer mechanism 64 includes a second support 641 mounted on the frame 1, a second linear guide rail mounted on the second support 641 along the Y-axis, a second slide block 642 slidably mounted on the second linear guide rail, and a mechanism mounted on the second support 641 for driving the second slide block 642 along the second linear guide rail. The system includes a second linear module A643 that slides along a linear guide rail, a second electric cylinder 644 that is vertically mounted on a second slide block 642, a second connecting frame 645 that is mounted at the output end of the second electric cylinder 644, and a material-picking gripper 646 mounted on the second connecting frame 645. The material-picking gripper 646 includes a cylinder body 6461 mounted on the second connecting frame 645, and two claws that are symmetrically mounted on the cylinder body 6461 and driven by the cylinder body 6461. The claws include a body 6462 that is slidably connected to the cylinder body 6461 and a first column 6463 with a semi-circular cross-section mounted on the body 6462.

[0048] In actual use, the filter screen 300 is vibrated to the second linear vibrator 62 via the second vibrating plate 61, and then the second linear vibrator 62 vibrates the filter screen 300 into the second distributor 63. Then, the second transfer mechanism 64 transfers the filter screen 300 in the second distributor 63 into the bearing seat 100. The action of the second transfer mechanism 64 in transferring the filter screen 300 is as follows: the second linear module A643 drives the second slide block 642 to slide along the second linear guide rail to the top of the second distributor 63, and then the second electric cylinder 644 drives the second connecting frame 645 to move down. At this time, the two claws close, so that the two first columns 6463 close and extend into the filter screen 300. Then the cylinder 6461 drives the two claws to separate, and the two first columns 6463 are used to tighten the inner wall of the filter screen 300, ensuring that the filter screen 300 can move synchronously with the picking claw 646. Then, the second electric cylinder 644 drives the second connecting frame 645 to rise. After the second linear module A643 drives the second slide 642 to move onto the bearing seat 100, the second electric cylinder 644 drives the second connecting frame 645 to move down, causing the second connecting frame 645 to move the material picking claw 646 down, causing the filter screen 300 to extend into the channel of the bearing seat 100 to achieve assembly with the bearing seat 100. Then, the cylinder body 6461 drives the two claws to close, and the second electric cylinder 644 drives the second connecting frame 645 to move up, causing the material picking claw to disengage from the filter screen 300.

[0049] In the above design, the structural design and specific implementation of the filter screen feeding mechanism 6 enable the picking up of the filter screen 300 and its assembly with the bearing seat 100.

[0050] Specifically: such as Figure 7 , Figure 8 and Figure 9 As shown, the bearing loading mechanism 7 includes a material rack 71 mounted on the frame 1, a pressing assembly 72 mounted on the frame 1, and a translation assembly 73 mounted on the material rack 71 for transferring the bearing 400 to the pressing assembly 72. The material rack 71 includes a third support A711 mounted on the frame 1, a third linear guide rail A mounted on the third support A711 along the X-axis, a third slide block 712 slidably mounted on the third linear guide rail A, and a third linear module A71 mounted on the third support A711 for driving the third slide block 712 to slide along the third linear guide rail A. 3. A third frame 719 fixedly mounted on the third slide block 712, several feeding rods 714 arranged along the X-axis on the third frame 719, several pusher plates 715 slidably mounted on the third slide block 712 along the Y-axis, and several third cylinders A716 fixedly mounted on the third slide block 712 for pushing the pusher plates 715 respectively. The height difference between the lower end of the feeding rod 714 and the third slide block 712 is greater than the height of a bearing 400. A guide seat 717 is also provided on the third slide block 712, and several feeding rods 714 are mounted on the guide seat 717. The material feeding holes 701 are one-to-one with the guide grooves corresponding to the pusher plates 715. The feeding rod 714 is also provided with a pin 718, which is located above the upper end face of the guide seat 717. The translation component 73 includes a third linear guide rail B731 arranged along the Y-axis on the lower end face of the third support A711, a sliding block 732 slidably arranged on the third linear guide rail B731, a third linear module B733 arranged on the third support A711 for driving the sliding block 732 to slide along the third linear guide rail B731, and a vertically arranged component on the sliding block. The No. 3 cylinder B734 on the 732 and the receiving plate 735 set at the output end of the No. 3 cylinder B734 are used to receive the bearing 400 pushed out by the push plate from the No. 3 slide 712. The pressing assembly 72 includes a No. 3 support B721 set on the frame 1, a No. 3 electric cylinder 722 set on the No. 3 support with the output end facing downward, a No. 3 pressure rod 723 set at the output end of the No. 3 electric cylinder 722, and a plurality of elastic plungers 724 arranged radially on the pressure rod. The No. 3 pressure rod 723 is provided with a step 702 for pressing the upper end face of the bearing 400.

[0051] It should be noted that the bearing 400 of the material rack 71 is received by the translation component 73, and then the bearing 400 in the translation component 73 is picked up by the pressing component 72 and assembled onto the bearing seat 100. The third frame 719 is provided with a slot, and the upper end of the feeding rod 714 is provided with a limiting protrusion that cooperates with the slot.

[0052] In actual use, a string of bearings 400 is strung on a feeding rod 714 removed from frame 719. After the feeding rod 714 strings the bearings 400 together, it is transferred by connecting pin 718, so that the upper end of the feeding rod 714 cooperates with frame 719 to achieve fixation. Then, the pin 718 is pulled out, and the bearings 400 automatically pull to the drop hole 701 under the action of gravity and are supported by slide block 712. Then, linear module A713 drives slide block 712 to move along linear guide rail A so that the bearings 400 on slide block 712 correspond to translation component 73. Then, cylinder A716 drives push plate 715 to move towards the bearing 400, so that the bearing 400 moves from slide block 712 to receiving plate 735. Then, cylinder A716 drives push plate 715 to reset. Then, the third linear module B733 drives the sliding block 732 to move along the third linear guide rail B731 to the side of the pressing component 72, so that the receiving plate 735 moves to directly below the pressing component 72. Subsequently, the third cylinder B734 drives the receiving plate 735 to rise, so that the inner wall of the inner ring of the bearing 400 on the receiving plate 735 squeezes the elastic plunger 724. The elastic force of the elastic plunger 724 on the bearing 400 ensures that the bearing 400 moves synchronously with the third pressure rod 723. Then, the third cylinder B734 drives the receiving plate 735 to move down, so that the receiving plate 735 disengages from the bearing 400. Then, the third linear module B733 drives the sliding block 732 to drive the third cylinder B734 and the receiving plate 735 to reset. Subsequently, the third electric cylinder 722 of the pressing assembly 72 drives the third pressure rod 723 to move downward, causing the third pressure rod 723 to drive the elastic plunger 724 and the bearing 400 to move downward synchronously. When the bearing 400 contacts the bearing 400 hole of the bearing housing 100, the third electric cylinder 722 continues to drive the third pressure rod 723 to move downward, using the step 702 to press the upper end face of the bearing 400 until the bearing 400 is assembled with the bearing housing 100. At this time, the frictional force between the bearing 400 and the bearing housing 100 is greater than the frictional force between the elastic plunger 724 and the bearing 400. Therefore, the third electric cylinder 722 driving the third pressure rod 723 to move upward can automatically complete the disengagement of the elastic plunger 724 from the bearing 400.

[0053] In the above design, the structural design and specific implementation of the bearing feeding mechanism 7 enable the automatic assembly of the bearing 400 and the bearing housing 100.

[0054] Specifically: such as Figure 10 and Figure 11As shown, the pin feeding and pressing mechanism 8 includes a fourth support 81 mounted on the frame 1, a fourth lifting frame 82 mounted on the fourth support 81, a fourth cylinder A83 mounted on the fourth support 81 for driving the fourth lifting frame 82 to rise and fall, an elastic element 84, a positioning plate 85 floatingly connected to the fourth lifting frame 82 via the elastic element 84, a fourth electric cylinder 86 mounted on the fourth support 81, and a fourth punch 87 mounted at the output end of the fourth electric cylinder 86. The positioning plate 85 is provided with a plurality of pin dropping holes 850. The frame 1 is also provided with a pneumatic feeding mechanism 88 that mates with one of the screw holes. The punch corresponds to one of the pin dropping holes 850. The frame 1 is also provided with a lifting and rotating drive mechanism 9 for lifting and rotating the pallet 2.

[0055] It should be noted that, for ease of understanding, the hole in the bearing housing 100 where the pin 500 is installed is referred to as the pin hole.

[0056] In actual use, when the pallet 2 moves to the position corresponding to the pin feeding and pressing mechanism 8, the lifting and rotating drive mechanism 9 drives the pallet 2 to rise and separate it from the conveyor line 3. Then, the fourth cylinder A83 drives the fourth lifting frame 82 to move down, so that the pin holes 850 of the positioning plate 85 correspond one-to-one with the pin holes on the bearing seat 100. Then, the air-blowing feeding mechanism 88 feeds a pin 500 into the corresponding pin hole to complete the pre-installation. Then, the fourth cylinder A83 drives the fourth lifting frame 82 to move up, and the lifting and rotating drive mechanism 9 drives the pallet 2 to rotate, so that the pin 500 pre-installed on the bearing seat 100 corresponds to the fourth punch 87. At this time, the other empty pin hole corresponds to the air-blowing feeding mechanism 88. Then, the air-blowing feeding mechanism 88 feeds the pin into the pin hole below to complete the first pin installation. The two pins 500 are pre-installed. Simultaneously, the No. 4 electric cylinder 86 drives the No. 4 punch 87 to press the pre-installed pins 500, so that the pins 500 are assembled on the bearing seat 100. Then, the No. 4 cylinder A83 drives the No. 4 lifting frame 82 to move upward again. Then, the rotary drive mechanism drives the tray 2 to rotate again, so that the pre-installed second pin 500 corresponds to the punch. Then, the No. 4 cylinder A83 drives the No. 4 lifting frame 82 to move downward. The elastic element 84 is compressed and deformed until the positioning plate 85 is positioned with the bearing seat 100 again. At this time, the upper end of the pre-installed second pin 500 passes through the corresponding screw hole of the positioning plate 85 and protrudes from the upper end face of the positioning plate 85. Then, the No. 4 electric cylinder 86 drives the No. 4 punch 87 to press the second pin 500, so that the pin 500 is assembled with the bearing seat 100.

[0057] In the above design, a pin feeding and pressing mechanism 8 can complete the assembly of two pins 500 and bearing housing 100. During assembly, the pins are automatically fed by the air-blowing feeding mechanism 88, and the pins can be fed and pressed at the same time, which improves efficiency.

[0058] Specifically: such as Figure 10and Figure 11 As shown, the lifting and rotating drive mechanism 9 includes a No. 5 support 91 mounted on the frame 1, a No. 5 lifting frame 92 mounted on the No. 5 support 91, a No. 5 cylinder A93 mounted on the No. 5 support 91 for driving the No. 5 lifting frame 92 to lift, a rotating positioning seat 94 mounted on the No. 5 lifting frame 92, and a No. 5 motor 95 mounted on the No. 5 lifting frame 92 for driving the rotating positioning seat 94 to rotate.

[0059] In actual use, the No. 5 lifting frame 92 is driven to rise by the No. 5 cylinder A93, which in turn drives the rotating positioning seat 94 to position the pallet 2 and lift it up. When the bearing housing 100 needs to rotate after completing the assembly of one pin 500, the No. 5 motor 95 drives the rotating positioning seat 94 to rotate, so that the pin hole of the other unassembled pin 500 in the bearing housing 100 corresponds to the air-blowing feeding mechanism 88.

[0060] In the above design, the structural design and specific implementation of the lifting and rotating drive mechanism 9 can effectively realize the rotation and lifting of the pallet 2, ensuring that the different nail positions of the bearing seat 100 in the pallet 2 receive the pins 500 and cooperate with the punch.

[0061] Specifically: such as Figure 10 and Figure 11 As shown, the lifting and rotating drive mechanism 9 also includes a lifting assembly 96 disposed on the fifth support 91. The lifting assembly 96 includes a fifth slider 961 slidably disposed on the fifth support 91 and a fifth cylinder B962 disposed on the fifth support 91 for driving the fifth slider 961 to slide.

[0062] In actual use, before the No. 5 lifting frame 92 rises, the output end of the No. 5 cylinder B962 retracts. When the No. 5 lifting frame 92 rises and needs to lift the tray 2, the output end of the No. 5 cylinder B962 extends to drive the No. 5 slider 961 to extend and enter under the No. 5 lifting frame 92 to support the No. 5 lifting frame 92.

[0063] In the above design, the structural design and specific implementation of the lifting and rotating drive mechanism 9 can support the No. 5 lifting frame 92 and prevent the No. 5 lifting frame 92 from being damaged by greater impact force when the pin 500 is impact assembled.

[0064] The second embodiment provided in this application is an assembly method for a bearing housing assembly of an air compressor. Using the aforementioned bearing housing assembly device, the method includes the following steps: S1, a tray 2 receives the bearing housing 100 transferred from the housing loading mechanism 4 at one end of the conveyor line 3 and then conveys it to the oil seal loading mechanism 5; S2, the oil seal loading mechanism 5 transfers the oil seal 200 onto the bearing housing 100; S3, the conveyor line 3 conveys the tray 2 to the corresponding position of the filter screen loading mechanism 6, where the filter screen loading mechanism 6 assembles the filter screen 300 onto the bearing housing 100; S4, the conveyor line 3 conveys the tray 2 along one side of the bearing loading mechanism 7, where the bearing 400 is assembled onto the bearing housing 100; S5, the conveyor line 3 conveys the tray 2 to the pin loading and pressing mechanism 8, where the pin loading and pressing mechanism 8 assembles the pin 500 into the mounting hole on the bearing housing 100.

[0065] In the above design, the assembly of the entire bearing housing 100 assembly is compact and highly automated.

[0066] In further detail, it should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
