Description

Technical Field

[0001] This utility model relates to the field of riveting and assembly technology, specifically to a blind rivet riveting device. Background Technology

[0002] Riveting is a non-removable connection method widely used in the automotive, bridge, railway, and aviation industries. Blind rivets are extensively used in aircraft structural assembly, with tens or even hundreds of thousands used in a single aircraft. During the blind riveting process, the rivet shank is attracted to the tail and then pops out. Failure to collect the waste shank can pollute the work area and pose a significant safety hazard to the aircraft.

[0003] According to Chinese Patent Publication No. CN219378368U, a device for collecting rivet pads from blind rivets is disclosed, comprising: a front end of a collection port, a middle part of a collection port, a rear end of a collection port, and a collection bottle; the collection bottle is installed below the middle part of the collection port; the rear end of the collection port is hung on a blind rivet gun. This device solves the management and quality problems associated with the scattering of tiny rivet pads during blind rivet riveting.

[0004] However, the above solution uses a thickened silicone collection port with the rear end fitted onto the outside of the rivet gun to fix the entire device. However, this fixing method is only applicable to a single type of rivet gun and has poor compatibility when facing different types of rivet guns. This results in the device being unable to be installed stably and is prone to loosening and falling off, affecting the collection effect of the gasket. Utility Model Content

[0005] The purpose of this invention is to provide a blind rivet riveting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a core-pulling rivet riveting device, comprising a receiving hopper, the receiving hopper being fixedly connected to an installation cylinder, the outer side of the receiving hopper being fixedly connected to a feeding pipe, one end of the feeding pipe being fixedly connected to a cylinder body, a slider being provided inside the cylinder body, the slider being fixedly connected to a guide hopper, a ball being provided at one end of the guide hopper, a collar being provided on the outer side of the installation cylinder, a fixing ring being installed on one side of the collar, the fixing ring being hinged to one end of a connecting plate, a clamping plate being installed at the other end of the connecting plate, and a rivet gun being provided on one side of the receiving hopper.

[0007] Preferably, the mounting sleeve is disposed on the outside of the rivet gun, and the receiving hopper is connected to the mounting sleeve and the feed pipe respectively.

[0008] Preferably, a relief groove is provided on the outer side of the mounting cylinder, and the mounting cylinder slides with the connecting plate through the relief groove. A thread is provided on the outer side of the mounting cylinder, and the mounting cylinder is threadedly connected to the collar through the thread.

[0009] Preferably, a limiting groove is formed on the inner wall of the mounting cylinder, and the limiting groove is slidably engaged by a clamping plate.

[0010] Preferably, a sliding block is provided on the outer side of the clamping plate, one end of the connecting plate is hinged to the sliding block, and the clamping plate and the sliding block are slidably engaged.

[0011] Preferably, the slider slides into the inside of the cylinder via a groove, and the slider is threaded into the cover plate via a thread.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a rotating collar to move horizontally on the thread on the outside of the mounting cylinder, thereby driving the connecting plate to move the clamping plate in the limiting groove. The clamping plate clamps and fixes the outside of the rivet gun, making the overall installation more stable and preventing loosening and falling off. At the same time, the movement of the clamping plate can be used to adapt to the outside of various rivet guns of different specifications, enhancing the actual use effect.

[0013] 2. This utility model also forms a collection cavity between the feed pipe and the inside of the cylinder to collect rivet gaskets. When the cylinder is tilted or even inverted, the slider moves synchronously inside the groove, thereby driving the cover plate to move. When the sleeve is tilted, the movement of the slider causes the ball to move towards the feed pipe, narrowing the gap in the feed pipe and preventing the gasket inside the collection cavity from falling off. When the cylinder is inverted, the ball similarly blocks the feed pipe to prevent the gasket from overflowing. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a blind rivet riveting device, including a receiving hopper 1, which is fixedly connected to an mounting cylinder 2. The receiving hopper 1 is funnel-shaped and made of rubber. The rubber ensures that the receiving hopper 1 fits snugly against the target area, preventing the gasket from flying out from the gaps in the receiving hopper 1. The mounting cylinder 2 is sleeved on the outside of a rivet gun 16 and extends into the receiving hopper 1 through one end of the rivet gun head. The outer side of the receiving hopper 1 is fixedly connected to the feed pipe 3, and one end of the feed pipe 3 is fixedly connected to the cylinder 4. The mounting cylinder 2 is sleeved on the outside of the rivet gun 16. The receiving hopper 1 is connected to both the mounting cylinder 2 and the feed pipe 3. The receiving hopper 1 can collect the shims that fly out of the rivet, avoiding the situation where the shims are difficult to collect. The shims enter the interior of the cylinder 4 through the feed pipe 3. A groove 5 is formed inside the cylinder 4, through which the cylinder 4 slides and engages with the outer side of the slider 6. The slider 6 has internal threads, which engage with the cover plate 9. The bottom surface of the cover plate 9 is fixedly connected to the protrusion. A slider 6 is installed inside the cylinder 4, and the slider 6 is fixedly connected to the guide hopper 7. The guide hopper 7 is funnel-shaped, and several leakage holes are opened on the outside of the guide hopper 7 to facilitate the leakage of the gasket. The gasket can pass through the leakage holes and be collected between the slider 6 and the guide hopper 7. By rotating the cover plate 9, it can be separated from the slider 6, and then the gasket in the collection cavity inside the cylinder 4 can be cleaned. A ball 8 is fixedly installed at one end of the feed hopper 7. The outer diameter of the ball 8 is adapted to the inside of the feed pipe 3. A collar 10 is provided on the outside of the mounting cylinder 2. One side of the collar 10 is rotatably engaged with a fixed ring 11. The fixed ring 11 is hinged to one end of the connecting plate 12, and the other end of the connecting plate 12 is hinged to the slider. The limiting groove 15 is slidably engaged with the clamping plate 14. A sliding block is provided on the outside of the clamping plate 14. One end of the connecting plate 12 is hinged to the sliding block. The clamping plate 14 and the sliding block are slidably engaged. The slider 6 is slidably engaged with the inside of the cylinder 4 through the sliding groove 5. A clearance groove 13 is provided on the outer side of the mounting cylinder 2, through which the mounting cylinder 2 slides with the connecting plate 12. Threads are provided on the outer side of the mounting cylinder 2, through which the mounting cylinder 2 is threadedly connected to the collar 10. A limiting groove 15 is provided on the inner wall of the mounting cylinder 2, which limits the movement of the clamping plate 14 to prevent displacement during movement. Working principle: In use, the mounting sleeve 2 is placed on the outside of the rivet gun head 16. By rotating the collar 10, the mounting sleeve 2 moves horizontally, which in turn moves the fixing ring 11 synchronously. The connecting plate 12 pushes the clamping plate 14 to move inside the limiting groove 15 until the clamping plate 14 clamps and fixes the outside of the rivet gun 16. By fixing the outside of the rivet gun 16 of different specifications, the clamping plate 14 can clamp and fix the outside of the rivet gun 16, enhancing the convenience of installation and improving the compatibility of the overall device. When installing rivets, the rivet gun 16 places the receiving hopper 1 on the outside of the connection. The rivet washer flies out and is blocked by the inner wall of the receiving hopper 1, flowing through the feed pipe 3 into the cylinder 4 and collecting between the slider 6 and the guide hopper 7. When the operator tilts the cylinder 4, the center of gravity shifts, causing the slider 6 to slide inside the groove 5, which causes the guide hopper 7 and the ball 8 to move towards the feed pipe 3 until the ball 8 partially blocks the feed pipe 3, reducing the gap in the feed pipe 3 and preventing the washer in the collection chamber from flying out. When the cylinder 4 is inverted, the ball 8 moves into the feed pipe 3, thereby sealing the feed pipe 3 and preventing the washer from flying out and causing pollution.
