Description

Technical Field

[0001] This utility model relates to the field of rivet technology, specifically to a quick installation device for external locking wire-drawing rivets. Background Technology

[0002] Brush rivets, also known as cup-type blind rivets, are structural blind rivets. After riveting, the broken part of the rivet core will be turned inside the groove of the rivet body, locking the rivet core. Brush rivets are divided into two types: internal locking and external locking. External locking brush rivets are suitable for industries such as automotive, electronics, and electrical cabinets, and are used for riveting various thin plates.

[0003] Existing rivet guns mainly use manual rivet insertion, which involves holding the rivet by hand and inserting the tail of the rivet into the gun head to lock it in place. When repeated fastening and riveting of metal sheets and pipes of the same specifications is required, manual rivet insertion is inefficient and can easily cause operator fatigue. Summary of the Invention

[0004] The purpose of this invention is to provide a quick installation device for external locking wire-pulling rivets to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick installation device for externally locking wire-pulling rivets, comprising a storage box, a pusher block movably disposed inside the storage box, an installation box fixedly connected to one side of the storage box, a winding assembly disposed inside the installation box, two connecting ropes connected to the winding assembly, an installation frame fixedly connected to the other side of the storage box, two installation plates fixedly connected symmetrically to the left and right sides of the installation frame, a connecting assembly disposed on the side of the installation plate, and a pusher assembly disposed on the top surface of the installation frame.

[0006] Preferably, the winding assembly includes a micro motor and a winding wheel. The micro motor is fixedly connected to the inner wall of the mounting box. One end of the winding wheel is fixedly connected to the output shaft of the micro motor.

[0008] Preferably, the pushing assembly includes an electric telescopic rod and a pushing cylinder. The electric telescopic rod is fixedly connected to the top surface of the mounting frame, and the pushing cylinder is fixedly connected to the telescopic end of the electric telescopic rod. Two through slots are provided on the front and rear sides of the pushing cylinder.

[0009] Preferably, the storage box has two sliding grooves on its left and right sides, and a switch is fixedly connected to the top surface of the storage box.

[0010] Preferably, the pusher block has two through holes at its left and right ends, and the end of the connecting rope away from the winding wheel is fixedly connected to the inside of the through holes.

[0018] The winding assembly 4 includes a micro motor 41 and a winding wheel 42. The micro motor 41 is bolted to the inner wall of the mounting box 3. One end of the winding wheel 42 is mounted on the output shaft of the micro motor 41 via a coupling. The end of the winding wheel 42 away from the micro motor 41 is rotatably connected to the inner wall of the mounting box 3 via a bearing. One end of the two connecting ropes 5 is attached to the inner side of the winding wheel 42.

[0019] The connecting assembly 8 includes a tension sensor 81, a U-shaped frame 82, and a rotating wheel 83. The tension sensor 81 is bolted to the side of the mounting plate 7. The U-shaped frame 82 is bolted to the side of the tension sensor 81 away from the mounting plate 7. The rotating wheel 83 is rotatably connected to the inner wall of the U-shaped frame 82 by a pin. The connecting rope 5 is wound and installed inside the rotating wheel 83.

[0020] The material pushing assembly 9 includes an electric telescopic rod 91 and a material pushing cylinder 92. The electric telescopic rod 91 is bolted to the top surface of the mounting frame 6, and the material pushing cylinder 92 is bolted to the telescopic end of the electric telescopic rod 91. Two through slots are opened on the front and rear sides of the material pushing cylinder 92.

[0021] The storage box 1 has two sliding grooves on its left and right sides, and the switch 10 is installed on the top surface of the storage box 1 by bolts.

[0022] Two through holes are opened at the left and right ends of the pusher block 2, and the end of the connecting rope 5 away from the winding wheel 42 is tied to the inside of the through hole.

[0023] The mounting box 3 is detachably connected to the side away from the storage box 1 by bolts with an inspection cover. The mounting frame 6 is hinged to the side away from the storage box 1 with a cover plate, and the cover plate is snapped into the mounting frame 6.

[0024] The battery 11 and control panel 12 are mounted on the inner wall of the mounting box 3 by bolts. The control panel 12 integrates switches and programmable controllers that are compatible with various electronic components. It is electrically connected to the micro motor 41, tension sensor 81, and switch 10 through wires. The battery 11 provides power to the entire device. It can operate various switches to control the opening and closing of the micro motor 41. The above electronic components are all existing technologies. Their specific structures, working principles and electrical connections are not described in detail here.

[0025] Working Principle: In use, the device is fixed to an external displacement mechanism, such as a reciprocating screw or robotic arm, via the mounting bracket 6 for precise positioning. The operator opens the cover plate on the side of the mounting bracket 7 and places the external locking rivets into the storage box 1. A signal is transmitted from switch 10 to control panel 12, which starts the micro motor 41. The micro motor 41 drives the winding wheel 42 to rotate, tightening the connecting rope 5. The connecting rope 5, through the rotating wheel 83 and tension sensor 81, pulls the pusher block 2 forward. The pusher block 2 pushes the entire row of rivets along the groove inside the storage box 1 until the foremost rivet abuts against the cover plate on the side of the mounting bracket 6. The tension sensor 81 detects that the tension has reached a certain value and transmits a signal to control panel 12. Control panel 12 then stops the micro motor 41 and starts the electric telescopic rod 91. 1. The pusher cylinder 92 extends, contacts the locking ring of the rivet, and pushes the rivet into the rivet hole. Then, the electric telescopic rod 91 drives the pusher cylinder 92 to retract. At the same time, the tension sensor 81 detects the decrease in tension and transmits a signal to the control panel 12. The control panel 12 starts the micro motor 41, which drives the winding wheel 42 to rotate. The winding wheel 42 rotates the connecting rope, and at the same time, the connecting rope 5 drives the pusher block 2 to move, so that the pusher block 2 pushes the rivet inside the storage box 1 forward. The rivet shank of the foremost rivet passes through the through groove on the side of the pusher cylinder 92 until the rivet abuts against the cover plate on the side of the mounting frame 6. The mounting frame 7 is aligned with the next rivet hole. The above operation is repeated, so that the rivet can be quickly installed into the rivet hole. The displacement mechanism drives the whole device to move, thereby realizing automated rivet installation. This utility model has the advantages of being easy to use and having good performance.
