Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 9 The present invention preferably provides a double-sided bearing press-fitting machine, comprising a base plate 1, a feeding conveyor belt 2 disposed on the base plate 1, a vertically movable parking box 3 disposed on one side of the feeding conveyor belt 2, a part-picking and moving device 4 disposed on the base plate 1 for moving sheet metal parts from the feeding conveyor belt 2 to the parking box 3, a vertical frame 11 disposed on the base plate 1, a conveyor tray 12 disposed on the vertical frame 11, an upper and lower clamping device 5 disposed on the vertical frame 11 for feeding sheet metal parts from the parking box 3 to the conveyor tray 12 for conveying, and a transverse drive disposed on the vertical frame 11 for conveying sheet metal parts to one side on the conveyor tray 12. The moving device 6 has a pressing structure 7 and a pressing structure 8 staggered on the front and rear sides of the conveying pallet 12. The pressing structure 7 includes a top pressing device 71 for pressing on the upper side, a bottom pressing device 72 for pressing on the lower side, and a bearing feeding device 73 that can sequentially feed bearings to the bottom pressing device 72. The pressing structure 8 includes a top pressing device 81 for pressing on the upper side, a bottom pressing device 82 for pressing on the lower side, and a bearing feeding device 83 that can sequentially feed bearings to the bottom pressing device 72. A material discharge groove 13 is provided at one end of the conveying pallet 12, and an integrated controller 14 is provided on the base plate 1. Workers place sheet metal parts on the loading conveyor belt, which automatically transports them to the working position of the picking and moving device. The picking and moving device clamps the sheet metal parts and moves them to a parking bin. The parking bin has a vertical movement function; when it moves upward, it lifts the sheet metal parts, which are then clamped by the vertical clamping device. A lateral drive then moves the vertical clamping device laterally, allowing the sheet metal parts to enter above the conveyor tray. The vertical clamping device then lowers the sheet metal parts, completing the loading process. Because the clamping device has multiple jaws for clamping the sheet metal parts, it moves the sheet metal parts already on the conveyor tray laterally for a short distance each time the work is completed, until finally reaching the end and being discharged from the ejector chute. The sheet metal parts on the conveyor tray are also subjected to bearing riveting through pressing structures one and two.

[0017] The part-retrieving and moving device 4 of this utility model includes a bracket 41 mounted on a base plate 1. A slide rail 42 and a slider 43 that slides at its upper limit are provided on the bracket 41. An electric push rod 44 is provided on one side of the bracket 41, with its movable end connected to the slider 43. A cylinder 45 is provided on the top of the slider 43. An upper plate 46 is provided on the movable end of the cylinder 45. A pneumatic suction cup 47 for adsorbing sheet metal parts is provided on one side of the upper plate 46. By pushing the electric push rod, the slider can be moved towards the parking box side under the limit of the slide rail. Then, the cylinder is activated, and the pneumatic suction cup adsorbs the sheet metal part. The cylinder then activates again to lift the upper plate, moving the adsorbed sheet metal part towards the parking box. Finally, the pneumatic suction cup deflates, lowering the sheet metal part.

[0018] In this invention, the upright frame 11 has a central recess 15, and the conveying pallet 12 is fixed inside the central recess 15. The conveying pallet 12 has a concave cross-section. Side wings 16 are provided on both sides of the top of the upright frame 11, and an electric push rod 31 is provided at the bottom of the parking box 3 and fixed to the base plate 1. The upright frame supports the conveying pallet, the conveying pallet is installed at the bottom of the central recess, and the side wings are used to install the upper and lower clamping devices and the lateral movement drive device. The bottom of the parking box moves up and down through the electric push rod 31 to send the sheet metal parts upward until the first jaw of the upper and lower clamping device clamps and removes them.

[0019] The upper and lower clamping device 5 of this utility model includes a first movable rail 51 disposed at the bottom of the left side wing 16, a first movable block 52 disposed at the bottom of the first movable rail 51, a second movable rail 53 disposed at the bottom of the right side wing 16, a second movable block 54 sleeved on the second movable rail 53, a second cylinder 55 fixed at the bottom of both the first movable block 52 and the second movable block 54, an intermediate plate 56 fixed at the movable ends of the two second cylinders 55, and a plurality of pneumatic grippers 57 for clamping sheet metal parts disposed at the bottom of the intermediate plate 56. The transverse drive device 6 includes a third electric push rod 61 disposed on the right side wing 16, a top push plate 62 fixedly disposed on the second movable block 54, and the movable end of the third electric push rod 61 fixedly connected to the top push plate 62. Moving rail one allows moving block one to move, while moving rail two allows moving block two to slide. When cylinder two is activated, it drives the intermediate plate to move up and down, enabling multiple starting grippers at the bottom of the intermediate plate to move up and down synchronously. The lateral drive device pushes and pulls the moving plate via electric push rod two, causing moving block two to move, thus allowing the entire intermediate plate to move laterally. The cooperation between the upper and lower clamping devices and the lateral drive device can be used to pick up sheet metal parts from the parking box and load them onto the conveyor tray. The sheet metal parts on the conveyor tray can be gradually transferred to the unloading chute side until the finished part is sent out from the unloading chute after riveting is completed.

[0020] The top pressing device 71 described in this utility model includes an electric push rod 711 located in the middle of the top of the support frame 11. A pressure rod 712 is provided at the movable end of the electric push rod 711, and a pressure head 713 for pressing down on the sheet metal part is provided at the bottom end of the pressure rod 712. The electric push rod 711 can drive the pressure rod to move up and down, thereby allowing the pressure head to press down on the riveting position of the sheet metal part, so that the bearing is riveted into the two sides of the sheet metal part.

[0021] The bottom pressing device 72 described in this utility model includes a bottom support 721 disposed on a central cavity 15. A movable plate 722, capable of vertical movement, is positioned at the upper limit of the bottom support 721. A mounting base 723 for supporting the bearing is fixed on the movable plate 722. An electric push rod 724 is disposed on one side of the bottom support 721. A ramp push plate 725 is fixed to the movable end of the electric push rod 724, with its narrow end resting on the bottom of the movable plate 722. The electric push rod 724 drives the ramp push plate 725 to move linearly back and forth at the bottom of the movable plate 722. Because the ramp push plate 725 is sloping with a narrow outer end and a wide inner end, this linear movement drives the movable plate 725 to move up and down, thereby pressing the bearing on the mounting base 722 upwards. The bearing on the mounting base 723 is fed to the mounting base by a bearing feeding device.

[0022] The bearing feeding device 73 of this utility model includes a feeding track 731 mounted on a base plate 1, a pusher seat 732 on one side of the feeding track 731, a lifting motor 733 mounted on the pusher seat 732, a translation motor 734 mounted on the lifting motor 733, a pusher plate 735 mounted on the movable end of the translation motor 734, a material placement groove 736 at the end of the pusher plate 735 aligned with the feeding track 731, and an alignment motor 737 on the feeding track 731 for auxiliary alignment. An alignment pin 738, which can be inserted into the center of the bearing, is mounted on the movable end of the alignment motor 737. When a worker places the bearing material onto the feeding track, the bearing is gradually moved towards the pusher plate and finally pushed into the material placement groove. Then, the lifting motor and translation motor are activated, which securely delivers the bearing in the material placement groove to the mounting base 1. The purpose of the feeding trough is to ensure the bearing is pushed securely. The bearing is first lifted, then pushed left and right, and finally lowered onto the mounting base. The alignment motor drives the alignment pins to insert into the bearing, allowing it to align during transport, limiting the delivery timing, and ensuring the bearing is actually delivered into the feeding trough.

[0023] The top pressing device 81 described in this utility model includes a top support 811 disposed on one side of the top of the upright 11. A movable plate 812, which can move up and down, is disposed at the upper limit of the top support 811. A pressing column 813 for pressing down sheet metal parts is provided at the bottom of the movable plate 812. An electric push rod 814 is provided on one side of the top support 811. A ramp push plate 815 is fixed on the movable end of the electric push rod 814. The narrow end of the ramp push plate 815 is placed on the top of the movable plate 812. A pin 816 is provided on the upper wall of the movable plate 812 and is inserted and connected to the upper side of the top support 811. A spring 817 is sleeved on the pin 816. The electric push rod 816 drives the ramp push plate 812 to move back and forth, thereby pressing down the movable plate 812 and causing it to move up and down. Consequently, the pressing column also moves up and down, thus pressing down the riveting position of the sheet metal parts. The second top pressing device works in conjunction with the first top pressing device to achieve downward pressing of the sheet metal parts on both sides. The function of the spring is to provide an upward pulling force to the second movable plate through its elasticity, so that the second movable plate can move upward by the pulling force when the second ramp push plate is not inserted.

[0024] The bottom pressing device 82 described in this utility model includes an electric push rod 821 disposed at the bottom of the base plate 1. A top rod 822 is disposed on the movable end of the electric push rod 821, and a recess for placing a bearing is provided at the top of the top rod 822. The electric push rod 821 can drive the top rod to move up and down, and the top cavity can hold the bearing. The bearing can be installed by the bearing feeding device 2.

[0025] The bearing feeding device 2 83 of this utility model includes a feeding track 2 831 set on a base plate 1, a pusher seat 2 832 set on one side of the feeding track 2 831, a lifting motor 2 833 set on the pusher seat 2 832, a translation motor 2 834 set on the lifting motor 2 833, a pusher plate 2 835 set on the movable end of the translation motor 2 834, and a pneumatic suction end 836 set at the end of the pusher plate 2 835, which can be aligned with the feeding track 2 831. The lifting motor 2 and the translation motor 2 realize the four-way transmission movement of the pusher plate 2. The pneumatic suction end is used to pneumatically suction and feed the bearing until the bearing is placed on the cavity.
