Description

Technical Field

[0001] This utility model relates to the field of mechanical processing and assembly automation technology, specifically to a semi-automatic riveting device. Background Technology

[0002] Riveting is a critical connection process widely used in precision manufacturing fields such as aerospace, automotive, and electronics. The assembly quality of rivets directly affects the structural strength, reliability, and long-term stability of the connection point, and is crucial to the overall safety of the product.

[0003] Currently, many applications, especially those involving small batches, diverse product types, or requiring manual workpiece positioning, still heavily rely on manual placement and riveting of rivets. Operators must hold the rivet in one hand and the tool in the other, which is not only inefficient and physically demanding, but also prone to causing rivet misalignment, insufficient or excessive riveting force due to visual errors, hand tremors, and uneven force control. This can lead to serious quality problems such as rivet misalignment, workpiece damage, loose connections, and even rivet failure, making it difficult to guarantee consistency.

[0004] While existing general-purpose automated assembly equipment is used in specific high-volume scenarios, it is difficult to effectively adapt to the miniaturization, high flexibility, and special process requirements of rivet assembly. It generally lacks a dedicated mechanism for efficient and reliable sorting and feeding of miniature rivets, lacks anti-deviation and anti-torsion designs to ensure precise positioning of rivets in the conveying and riveting positions, and has insufficient precise start-stop control and consistency assurance for impact riveting forces. This limits its applicability in scenarios requiring high-precision riveting and operational flexibility. Utility Model Content

[0020] The rivet transfer mechanism 200 includes a second cylinder 201, a cylinder fixing block 202, a cover plate 203, a conversion shaft 204, a rivet flat delivery rod 205, a rivet guide block 206, a rivet fixing base 207, a baffle 208, a third panel 209, a left support plate 210, and a right support plate 211. The third panel 209 is positioned above the second panel 700 via a left support plate 210 and a right support plate 211. A rivet guide block 206 is mounted above the third panel 209, and a rivet flat feed rod 205 is guided on the rivet guide block 206. The rivet flat feed rod 205 is limited by a cover plate 203 on the rivet guide block 206.

[0023] The working principle is as follows: First, turn on the ordinary controller and digital display controller, then pour the rivets into the rivet vibratory feeder. The rivet vibratory feeder uses vibration to sort the rivets, which are then transported by guide rails to the rivet flat conveying mechanism. When the rivets are transported to the rivet flat conveying mechanism, the vibration of the rivet flat conveying mechanism is used to transport and correct their posture, and they are smoothly pushed forward in a straight line until the rivets are delivered to the rivet flat conveying mechanism. The operator places one foot on the foot switch and uses the other hand to align the hole point of the product to be riveted with the rivet in the groove of the rivet fixing base, embedding it into the product. Then, the operator steps on the foot switch, and the rivet pressing mechanism is driven by air pressure. The first cylinder moves with a large impact force until the punch hits the rivet in the product, causing it to burst open in a flower shape and be fixed in place.

[0024] Once the rivet is crimped, release the foot pedal, and the first cylinder returns to its original position. Subsequently, the second cylinder in the rivet transfer mechanism is pushed by air pressure, and the rivet delivery rod will send the next rivet along the track to the rivet groove in the rivet fixing base, waiting for the next riveting operation. This process can be repeated.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
