Description

Technical Field

[0001] This utility model belongs to the field of riveting devices, and specifically relates to an automatic riveting device. Background Technology

[0002] In the field of machining, riveting is an important means of connecting parts, especially in the multi-layered structure connection of disc-shaped workpieces. Traditional riveting operations usually rely on manual labor or semi-automatic equipment, which suffers from low efficiency, unstable accuracy, and high labor intensity. With the improvement of industrial automation, the market has placed higher demands on the intelligence, efficiency, and precision of riveting devices.

[0003] Existing riveting equipment has the following shortcomings in terms of structural design and functional implementation:

[0004] Low efficiency of multi-station collaboration: Traditional equipment mostly adopts a single-station operation mode. The processes of workpiece loading, parts assembly, riveting and unloading need to be completed step by step, relying on manual transfer of workpieces, resulting in long production cycle time and difficulty in meeting the needs of mass production.

[0005] Insufficient feeding accuracy for complex parts: For small precision parts such as rivet cores and press-fit sleeves, existing feeding devices often cause misalignment of parts due to positioning deviations or unstable gripping, affecting the press-fit quality and even causing equipment failure.

[0006] The integration of inspection and automation is disconnected: some equipment lacks real-time inspection, making it impossible to dynamically calibrate the position of workpieces and the assembly status of parts. After riveting is completed, manual sampling inspection is required, which increases the cost of quality control.

[0007] The unloading process is not continuous: the unloading process often uses fixed robotic arms or simple conveyor belts, which are difficult to adapt to the flexible transfer of workpieces of different specifications, and the connection efficiency with subsequent processes (such as sorting and packaging) is low.

[0008] To address the aforementioned issues, while multi-station rotary riveting equipment has emerged in the existing technology, there is still room for improvement in areas such as the rationality of station layout, precise feeding of multiple parts, and the synergy between visual inspection and automated control. For example, how to achieve efficient stacking of rivet cores, riveting sleeves, and disc-shaped workpieces through integrated design, how to use visual inspection to calibrate station deviations in real time, and how to improve the coordination accuracy of various actuators through intelligent control have become key directions for optimizing current riveting devices.

[0009] Therefore, there is an urgent need for a riveting device that can achieve multi-station cyclic operation, precise feeding, dynamic detection and automated unloading, in order to meet the needs of high-precision and high-efficiency industrial production. Utility Model Content

The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

A work cover 2 is provided on the top of the workbench 1. An indexer 13 is provided in the center of the top of the workbench 1. A rotating disk 11 is fixedly installed on the rotating end of the top of the indexer 13. A vision inspection device 9 is hollowed out in the middle of the rotating disk 11. The vision inspection device 9 is fixedly installed on the fixed end of the top of the indexer 13. Six sets of bearing seats 12 are evenly arranged around the top of the rotating disk 11. Two disc-shaped workpieces 01 are manually placed side by side along the length direction on the top of the bearing seats 12.

[0037] Along the top of the workbench 1, around the rotating disk 11, two sets of material transfer devices 5, two sets of riveting cylinders 6, and an automatic unloading device 8 are arranged in a clockwise direction corresponding to five sets of bearing seats 12. The last set of bearing seats 12 is matched with the position of the vision inspection device 9. Each of the two sets of material transfer devices 5 has a feeding device 4 on one side. The two feeding devices 4 are respectively equipped with rivet cores 03 and riveting sleeves 02. A conveyor belt 3 is arranged at the rear of the top of the workbench 1 and near the automatic unloading device 8.

The lifting shaft 812 of the unloading robot 81 drives the finger cylinders 83 to descend and clamp the disc-shaped workpiece 01, and transfers the disc-shaped workpiece 01 onto the conveyor belt 3 through the rotary joint 811.

[0050] In a preferred embodiment of the present invention, the two clamping ends at the bottom of the finger cylinder 2 83 are further fixedly equipped with grippers 2 84.

[0051] Specifically, such as Figure 2-3 As shown, through the coordinated operation of the rotary joint 811 and the lifting shaft 812 set in the unloading robot 81, the finger cylinder 83 can rotate in the direction of its rotary joint 811 and move up and down with the lifting shaft 812, thereby realizing the operation process of the finger cylinder 83 taking the disc-shaped workpiece 01 out of the carrier seat 12 and turning it to be placed on the conveyor belt 3 for conveying.

[0052] In a preferred embodiment of this utility model, the industrial control computer 23 is further disposed on one side of the work cover 2 and close to the conveyor belt 3.
