Description

Technical Field

[0001] The present invention relates to the technical field of riveting devices, in particular to a riveting machine with automatic loading and unloading capabilities. Background Art

[0002] Pressure riveting machine (also known as riveting machine, rotary riveting machine, riveting machine, rolling riveting machine, etc.) is a new type of riveting equipment developed based on the principle of cold rolling. Pressure riveting is a riveting method that uses the static pressure generated by the pressure riveting machine to upset the rivet rod to form an upset head. The riveted parts produced by pressure riveting have the characteristics of good surface quality, small deformation and high connection strength. Therefore, in actual operation, as long as the structural process allows, pressure riveting is preferred.

[0003] Traditional riveting operations mostly rely on manual operation. Workers need to manually place the workpiece to be riveted on the riveting station and place the rivet at the position to be riveted on the workpiece, and then perform the riveting operation. After that, the riveted workpiece is removed and transferred to the next process. Manual loading and unloading is prone to operational errors, such as inaccurate workpiece placement and untimely rivet supply, which affects the quality of riveting, increases the defective rate, and increases production costs.

[0004] Although some existing automatic riveting equipment has achieved automation to a certain extent, such as the patent with authorization announcement number CN222660033U, which discloses a riveting machine, the vibration plate is continuously vibrated by the vibration seat, so that the rivets can enter the feed pipe from the feed port and be transmitted to the rivet input pipe through the feed pipe, thereby realizing the automatic rivet loading operation of the riveting machine. At the same time, by adjusting the rivet outlet position and changing the position of the two rivet input pipes, the rivets are output from the two discharge ports in turn, and cooperate with the force-bearing components to realize continuous riveting operation.

[0005] However, in the above device, the loading and unloading of the workpiece to be riveted is not automated, and the device needs to be stopped during the riveting process to wait for the workpiece to be loaded. The overall operating efficiency of the device needs to be improved. Summary of the Invention

DETAILED DESCRIPTION

[0027] First of all, it should be noted that in the various embodiments described, identical components are provided with identical reference numerals or identical component names, wherein the disclosure contained throughout the entire description can be transferred to the same components having the same reference numerals or identical component names. Positional designations selected in the description, such as top, bottom, lateral, etc., also refer to the directly described and illustrated figures and are transferred to the new position in the event of a change in position.

[0028] The embodiment provides a riveting machine with automatic loading and unloading, such as Figures 1-8As shown, it includes a frame 1 and a riveting mechanism 2 arranged on one side of the top of the frame 1. The riveting mechanism 2 includes a liftable riveting head 21. Specifically, the riveting head 21 is hydraulically driven to rise and fall. A riveting station is provided below the riveting head 21. It also includes: a conveyor belt 3, which is arranged on the frame 1 and is located on one side of the riveting station for conveying riveted workpieces; an alternating feeding mechanism 4, which is arranged above the middle of the frame 1 and includes two feeding tables 41 and a driving mechanism 42. The driving mechanism 42 is used to drive the two feeding tables 41 to move horizontally and alternately to the riveting station to ensure that when one feeding table 41 is riveting, the other feeding table 41 can be prepared for loading, and the unloading group Part 5 is installed on each feeding table 41, and the unloading component 5 is used to transfer the riveted workpiece from the feeding table 41 to the conveyor belt 3; the transferring mechanism 6 is arranged on the other side of the top of the frame 1; the workpiece tray 7 to be riveted is arranged outside the frame 1 and on the same side as the transferring mechanism 6; the transferring mechanism 6 is used to transfer the workpiece to be riveted in the tray 7 to the feeding table 41; and the automatic nail feeding mechanism 8 is arranged on the frame 1 and located above the alternating feeding mechanism 4, including a nail feeding head 81 and an XYZ three-axis moving module 82, the XYZ three-axis moving module 82 can drive the nail feeding head 81 to position to the target riveting position of the workpiece to be riveted on the feeding table 41 for feeding nails.

[0029] It should be noted that: the workpiece to be riveted is continuously supplied through the material tray 7, the transfer mechanism 6 transfers the workpiece to be riveted in the material tray 7 to the adjacent feeding table 41, and then the rivet is sent to the target riveting position of the workpiece to be riveted by the automatic nail feeding mechanism 8. Afterwards, the alternating feeding mechanism 4 drives the two feeding tables 41 to exchange positions to move the workpiece to be riveted under the riveting head 21, and then the riveting head 21 is lowered to rivet the workpiece. After the riveting is completed, the unloading assembly 5 transfers the riveted workpiece from the feeding table to the conveyor belt 3, and the conveyor belt 3 automatically transfers the workpiece to the next process. During the entire working process, the various mechanisms cooperate to achieve efficient and continuous operation of automatic loading and unloading and riveting.

[0030] In the embodiment, Figure 2 and Figure 3As shown, the driving mechanism 42 includes a mounting frame 421, which is fixed to the middle of the top of the frame 1. A synchronous belt drive assembly 422 is installed in the mounting frame 421 along the X-axis. Slide plates 423 are fixed on both sides of the synchronous belt of the synchronous belt drive assembly 422 vertically, so that the rotation of the synchronous belt of the synchronous belt drive assembly 422 drives the two slide plates 423 to move synchronously in the opposite direction. Slide rails 424 are installed on both sides of the top of the mounting frame 421 along the X-axis. The two slide plates 423 are fixed on both sides of the synchronous belt of the synchronous belt drive assembly 422 vertically. 23 all slide through the mounting frame 421 and are respectively slidably connected to the two slide rails 424. The top of each slide plate 423 is slidably connected to a slide 425 along the Y axis. The feeding table 41 is fixedly connected to the slide 425 through an L-shaped connecting frame 426. Two guide grooves 428 are symmetrically provided on the mounting frame 421. A guide rod 427 is fixedly connected to the bottom of each slide 425. The lower end of the guide rod 427 is slidably connected to the guide groove 428 on the same side. The two guide grooves 428 are both bow-shaped and arranged relative to each other.

[0031] It should be noted that: when one feeding table 41 is in the riveting station, the other feeding table 41 is ready to load the material. After the two feeding tables 41 complete the riveting and loading respectively, the synchronous belt of the synchronous belt drive assembly 422 rotates, so that the two slides 423 slide synchronously in the opposite direction along the corresponding slide rails 424. As the slide 423 slides, the two slides 425 are gradually aligned in the Y-axis direction. However, since the guide rod 427 is constrained by the guide groove 428, the two slides 425 are aligned on the corresponding slide 423 along the Y-axis direction. The two slides 423 are moved away from each other, and the two feed tables 41 are moved away from each other and avoid each other. Then, as the two slides 423 continue to move, the guide rods 427 continue to be constrained by the guide grooves 428, so that the two slides 425 move in the opposite direction and reset on the corresponding slides 423. Finally, the feed table 41 initially located on one side of the riveting station moves to the other side, and the feed table initially located on the other side moves to the side of the riveting station, thereby ensuring that the two feed tables 41 move to the riveting station alternately in sequence.

[0032] In the embodiment, Figure 6 As shown, the transfer mechanism 6 includes a material picking assembly and a cylinder 2 62. The cylinder 2 62 is installed on the frame 1 along the X-axis. The material picking assembly includes a suction cup rod 611 and a cylinder 1 612. The suction cup rod 611 is installed on the output end of the cylinder 1 612. The cylinder 1 612 is installed on the output end of the cylinder 2 62 along the Z-axis. There are two material picking assemblies. A guide rail 63 is connected to the frame 1 for sliding along the X-axis. The guide rail 63 is fixed to the output end of the cylinder 2 62. The cylinders 1 612 of the two material picking assemblies are respectively installed at different positions on the guide rail 63. A material receiving platform 64 is fixedly connected to the frame 1 between the feeding platform 41 and the material tray 7. The material receiving platform 64 is used to temporarily store the workpieces to be riveted transferred by the material picking assembly.

[0033] It should be noted that the initial positions of the suction cup rods 611 of the two material-taking components of the transfer mechanism 6 are respectively located directly above the material receiving platform 64 and the material barrel 75, and the telescopic end of the second cylinder 62 is in a retracted state. No workpiece to be riveted is placed on the material receiving platform 64 and the feeding platform 41. The telescopic end of the cylinder 1 612 above the material barrel 75 is extended to lower the corresponding suction cup rod 611 to contact the workpiece to be riveted in the material barrel 75 and adsorb it. The telescopic end of the cylinder 1 612 is then retracted to lift the adsorbed workpiece to be riveted to a preset height, and then the telescopic end of the cylinder 2 62 is extended. The end is extended, so that the guide rail 63 drives the two material-picking components to move to one side of the feeding platform 41 along the X-axis in sequence, until the suction cup rod 611 initially located directly above the material receiving platform 64 comes directly above the feeding platform 41, and the suction cup rod 611 initially located directly above the barrel 75 and adsorbing the workpiece to be riveted comes directly above the material receiving platform 64. Then, the telescopic end of the cylinder 1 612 corresponding to the suction cup rod 611 adsorbing the workpiece to be riveted is extended, and the workpiece to be riveted is released to the material receiving platform 64 through the suction cup rod 611, and then, the telescopic end of the cylinder 1 612 currently located above the material receiving platform 64 is retracted. , and then the telescopic end of the second cylinder 62 is retracted to reset the two material-taking components on the guide rail 63 to the initial state. Subsequently, the telescopic ends of the two cylinders 1 612 are extended synchronously to make the two suction cup rods 611 respectively descend to contact and adsorb the workpieces to be riveted on the receiving platform 64 and in the barrel 75. Then, the telescopic ends of the two cylinders 1 612 are retracted and reset synchronously, and then the telescopic end of the second cylinder 62 is extended to transfer the workpieces to be riveted in the barrel 75 to the top of the receiving platform 64, and the workpieces to be riveted on the receiving platform 64 are transferred to the top of the feeding platform 41. Then, the two cylinders 1 The telescopic end of 612 extends synchronously, and the workpieces to be riveted are released through the two suction cup rods 611, so that the two workpieces to be riveted are placed on the feeding table 41 and the receiving table 64 respectively. After the placement is completed, the telescopic ends of the two cylinders 612 are retracted and reset synchronously, and the telescopic end of the cylinder 2 62 is retracted and reset. In this way, the above operations are repeated to realize the step-by-step feeding of "barrel 75→receiving table 64→feeding table 41", ensuring synchronization with the alternating feeding mechanism 4. Specifically, the transfer mechanism 6 always feeds the other adjacent feeding table 41 when one feeding table 41 is in the riveting station.

[0034] In the embodiment, Figure 7 and Figure 8As shown, the material tray 7 includes a mounting base 71, a turntable 72, a cylinder three 74 and a barrel 75. The turntable 72 is rotatably mounted on the top of the mounting base 71. A motor 73 for driving the turntable 72 to rotate is installed in the mounting base 71. A plurality of barrels 75 are arranged circumferentially on the turntable 72. The barrel 75 is a structure with openings at both ends. A support plate 76 is slidably connected to the barrel 75. A plurality of through openings 721 that are connected to the interior of the barrel 75 are opened on the turntable 72. A cylinder three 74 is installed in the mounting base 71. The telescopic end of the cylinder three 74 passes through the mounting base 71 and is fixedly connected to a top plate 77. The size of the top plate 77 matches the through opening 721.

[0035] It should be noted that: the turntable 72 is driven to rotate by the motor 73 so that the turntable 72 opening 721 corresponding to the target barrel 75 is aligned with the top plate 77 in the Z-axis direction, and multiple workpieces to be riveted are stacked above the support plate 76 in all barrels 75. The telescopic end of the cylinder three 74 is extended to drive the top plate 77 to move up to the opening 721 passing through the turntable 72 to lift the support plate 76, ensuring that the topmost workpiece to be riveted is at the material taking height for the transfer mechanism 6. After all the workpieces to be riveted in a barrel 75 are transferred, the telescopic end of the cylinder three 74 is retracted and reset, and the turntable 72 is driven to rotate again by the motor 73, and the upper and lower openings 721 of the turntable 72 are switched to come directly above the top plate 77, and the above-mentioned lifting action of the top plate 77 on the support plate 76 is repeated to achieve continuous feeding.

[0036] In the embodiment, Figure 5 As shown, the XYZ three-axis moving module 82 includes an X-axis linear module 821, a Y-axis linear module 822 and a Z-axis linear module 823. Specifically, the Z-axis linear module 823 adopts a small cylinder, and the nail feeding head 81 is installed on the output end of the Z-axis linear module 823. The Z-axis linear module 823 is installed on the output end of the Y-axis linear module 822. The two X-axis linear modules 821 are respectively installed on both sides of the Y-axis of the mounting frame 421. A fixed plate 824 is fixed between the output ends of the two X-axis linear modules 821, and the Y-axis linear module 822 is installed on the fixed plate 824.

[0037] In the embodiment, Figure 5 As shown, the automatic nail feeding mechanism 8 also includes a vibration disk 83 and a pneumatic nail feeding tube 84. The vibration disk 83 is installed on the main body of the riveting mechanism 2 for storing and sorting rivets. The two ends of the pneumatic nail feeding tube 84 are respectively connected to the discharge end of the vibration disk 83 and the nail feeding head 81.

[0038] It should be noted that: after the transfer mechanism 6 places a workpiece to be riveted on the feeding table 41, the rivets are sorted by the vibration plate 83 and then transported to the rivet feeding head 81 through the pneumatic rivet feeding tube 84, and the rivet feeding head 81 is driven by the XYZ three-axis moving module 82 to be positioned to the target rivet position of the workpiece to be riveted on the feeding table 41 for feeding.

[0039] In the embodiment, Figure 2 As shown, the unloading assembly 5 includes an electric push rod 51 and a push plate 52. The push plate 52 is slidably connected to the feeding table 41. The side of the feeding table 41 close to the conveyor belt 3 is not closed, so that the workpiece can be pushed from the feeding table 41 to the conveyor belt 3 through the push plate 52. The electric push rod 51 is installed on the connecting frame 426, and the push plate 52 is transmission-connected to the telescopic end of the electric push rod 51.

[0040] It should be noted that: the rivet head 21 is lowered to rivet the workpiece to be riveted on the feeding table 41 at the riveting station. After the riveting is completed, the telescopic end of the electric push rod 51 of the blanking component 5 is extended, so that the push plate 52 pushes the riveted workpiece out of the feeding table 41 and falls onto the conveyor belt 3, and the conveyor belt 3 automatically transfers the riveted workpiece to the next process.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
