Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a riveting machine feeding mechanism. Background Technology

[0002] In modern industrial production, riveting machines are widely used in various fields such as mechanical assembly, automobile manufacturing, and electronic equipment assembly to achieve efficient and reliable riveting operations. Existing riveting machines are typically equipped with a rivet feeding mechanism to sequentially deliver rivets from a storage device to the riveting position. However, existing rivet feeding mechanisms have some shortcomings in practical applications. For example, they suffer from poor stability during the feeding process, easily leading to problems such as rivet jamming and missed rivets, affecting the efficiency and quality of riveting operations. Furthermore, most existing rivet feeding mechanisms are complex in structure, making maintenance and debugging difficult, thus increasing production costs. Therefore, designing a rivet feeding mechanism that is simple in structure, stable in operation, and easy to maintain is of great significance for improving the performance and reliability of riveting machines.

[0015] Example 1: Figures 1-2 A nail feeding mechanism for a riveting machine is shown, which aims to solve the problems of unstable nail feeding, low efficiency, and easy nail jamming in the prior art. (Refer to...) Figures 1 to 4 The riveting machine feeding mechanism of this utility model mainly includes a frame 1, a feeding tube 2, a nail inlet 3, a nail outlet 4, a nail pusher assembly, and a detection mechanism.

[0016] The frame 1 is the basic structure of the entire nail feeding mechanism, with a nail feeding tube 2 fixedly connected to its top. One end of the nail feeding tube 2 is fixedly connected to a nail inlet 3, and the other end is fixedly connected to a nail outlet 4. A nail pushing assembly is installed inside the nail feeding tube 2, which includes a nail pushing rod 5, a drive motor 6, and a slide rail 7. One end of the nail pushing rod 5 is fixedly connected to a nail pushing head 8, and the other end is fixedly connected to a drive block 9. The drive motor 6 is fixedly connected to the bottom of the drive block 9, and the drive motor 6 is fixedly connected to the bottom of the frame 1, with its drive end penetrating the frame 1 and fixedly connected to the drive block 9. The slide rail 7 is slidably connected to the outside of the nail pushing rod 5, and both ends of the slide rail 7 are fixedly connected to the inner wall of the nail feeding tube 2 to ensure the stability and accuracy of the nail pushing rod 5 when sliding on the slide rail 7.

[0017] A guide block 10 is installed inside the rivet inlet 3. Multiple guide grooves 11 are formed on the surface of the guide block 10, and the shape of the guide grooves 11 matches the shape of the rivet. The guide block 10 can initially position the rivet entering the rivet feed tube 2, preventing the rivet from accumulating or tilting at the rivet inlet 3, ensuring that the rivet can smoothly enter the rivet feed tube 2. The design of the guide grooves 11 allows the rivet to slide along a predetermined path when entering the rivet feed tube 2, reducing unnecessary friction and obstruction, and improving rivet feeding efficiency.

[0018] A detection mechanism is installed below the rivet outlet 4. This mechanism includes a sensor 12, a controller 13, and an alarm 14. The sensor 12 is fixed to the bottom of the rivet outlet 4, and its output is electrically connected to the controller 13. The output of the controller 13 is also electrically connected to the alarm 14. The detection mechanism can monitor the number and status of rivets at the rivet outlet 4 in real time. When a jammed or missing rivet is detected, the controller 13 can control the alarm 14 to sound an alarm, reminding the operator to handle the situation promptly and avoid production interruptions caused by jammed or missing rivets, thereby improving production efficiency and equipment stability.

[0019] Specifically, the working principle of the rivet pusher assembly is as follows: After receiving a control signal, the drive motor 6 starts to rotate. The rotation of the drive motor drives the rivet pusher rod 5 to slide on the slide rail 7 via the drive block 9. The rivet pusher head 8 is fixed to one end of the rivet pusher rod 5. The shape and size of the rivet pusher head 8 are designed to match the end of the rivet so as to make close contact with the rivet during the rivet pusher process. The rivet pusher rod 5 moves forward along the sliding direction of the slide rail 7, pushing the rivets in the rivet inlet 3 one by one into the rivet feed tube 2. After the rivet pusher head 8 pushes a set of rivets, the drive motor 6 rotates in the opposite direction, and the drive block 9 drives the rivet pusher rod 5 back to the starting position for the next rivet feed. The design of the slide rail 7 ensures that the rivet pusher rod 5 maintains linear motion throughout the entire movement, reducing lateral offset and vibration, and improving the stability and accuracy of the rivet feed.

[0020] The working principle of the guide block 10 is as follows: The guide block 10 is installed inside the rivet inlet 3, and its surface has multiple sets of guide grooves 11. The shape of the guide grooves 11 matches the shape of the rivet, and can be circular, elliptical, or rectangular, depending on the shape of the rivet. When the rivet enters the feed tube 2 from the rivet inlet 3, the guide grooves 11 guide the rivet to slide into the feed tube 2 along a predetermined path. The design of the guide grooves 11 not only reduces the friction of the rivet when entering the feed tube 2, but also prevents the rivets from accumulating or tilting at the rivet inlet 3, ensuring that each rivet can enter the feed tube 2 accurately. In addition, the guide block 10 can be made of wear-resistant and corrosion-resistant metal or plastic materials to extend its service life and improve its performance.

[0021] The working principle of the detection mechanism is as follows: Sensor 12 is installed at the bottom of the rivet outlet 4 to monitor the number and status of rivets at the outlet 4 in real time. Sensor 12 can be a photoelectric sensor, proximity sensor, or pressure sensor, etc., selected according to the actual application scenario. When a rivet is fed out from the outlet 4, sensor 12 can detect the presence and number of rivets. Controller 13 receives the signal from sensor 12 and processes it. When controller 13 detects that the number of rivets at the outlet 4 is insufficient or that a rivet is stuck, controller 13 controls alarm 14 to sound an alarm, reminding the operator to handle the situation promptly. Alarm 14 can be an audible and visual alarm or a display screen, etc., determined according to actual needs. In addition, controller 13 can also communicate with the riveting machine's control system to achieve automated control. When a stuck rivet or a missing rivet is detected, the control system can automatically stop the operation of the rivet feeding mechanism to avoid equipment damage.

[0022] Specific Embodiment 1: The riveting machine feeding mechanism of this utility model is applied to a common automatic riveting machine. Assume the main function of the riveting machine is to feed rivets one by one into the riveting position and fix them to the workpiece through the riveting head. First, install the feeding mechanism of this utility model on the riveting machine, ensuring that the rivet inlet 3 is connected to the rivet storage device and the rivet outlet 4 matches the riveting head. The operator pours the rivets into the storage device, and the rivets enter the rivet inlet 3 through the bottom opening of the storage device. The guide groove 11 of the guide block 10 initially positions the rivets and guides them into the feeding tube 2. When the rivets enter the feeding tube 2, the drive motor 6 receives a control signal and begins to rotate, driving the push rod 5 to slide on the slide rail 7 through the drive block 9. The push head 8 pushes the rivets one by one towards the outlet 4. When the rivets reach the outlet 4, the sensor 12 detects them. If the number of rivets is normal and there is no jamming, the controller 13 maintains normal operation. If a stuck or missing rivet is detected, the controller 13 will activate the alarm 14 to alert the operator. The operator can manually adjust the rivet position at the rivet inlet 3 or check for foreign objects inside the rivet feeding tube 2 to ensure the normal operation of the rivet feeding mechanism.

[0023] Specific Embodiment 2: The riveting machine feeding mechanism of this utility model can also be applied to large-scale industrial production lines. Assume that the riveting machine on the production line needs to continuously feed rivets into multiple stations for riveting. In this application scenario, the stability of the feeding mechanism is particularly critical. When installing the feeding mechanism of this utility model, it is necessary to ensure the stability of the frame 1 and the straightness of the feeding tube 2. The rivet inlet 3 is connected to a central storage device, which distributes the rivets evenly to the inlets 3 of each feeding mechanism through pipes. The design of the guide block 10 and guide groove 11 ensures that the rivets can smoothly enter the feeding tube 2. The drive motor 6 uses a high-performance servo motor to ensure that the sliding of the push rod 5 on the slide rail 7 is more stable and precise. The sensor 12 can use multiple sets of photoelectric sensors, installed at different positions of the rivet outlet 4, to achieve multi-point detection. The controller 13 can communicate with the central control system of the production line. When a jammed or missing rivet is detected, the central control system can automatically adjust the operating speed of the production line or stop some equipment to avoid a complete interruption of the production line. Alarm 14 can employ multi-mode alarm devices, such as audible and visual alarms and displays, so that operators can quickly detect and handle problems.

[0024] Specific Embodiment 3: The riveting machine feeding mechanism of this utility model can also be applied to the field of precision assembly. For example, in the assembly process of electronic products, it is necessary to feed small rivets one by one into designated positions. In this application scenario, the accuracy and stability requirements of the feeding mechanism are higher. When installing the feeding mechanism of this utility model, a high-precision slide rail 7 and a drive motor 6 need to be selected. The design of the guide block 10 and the guide groove 11 can be more refined to accommodate small rivets of different shapes and sizes. The sensor 12 can be a high-sensitivity proximity sensor or photoelectric sensor to ensure accurate detection of each rivet. The controller 13 can integrate more powerful processing capabilities to achieve millisecond-level real-time monitoring and feedback. The alarm 14 can be a small audible and visual alarm device, installed at the front of the feeding mechanism so that operators can quickly detect and handle problems. In addition, to further improve the feeding accuracy, a small positioning pin can be installed at the front end of the pusher head 8 to ensure that the rivet is accurately aligned when entering the feeding tube 2.

[0025] Specific Embodiment 4: The riveting machine feeding mechanism of this utility model can also be applied to body riveting in the automotive industry. Assume that the riveting equipment in an automotive factory needs to feed rivets of different specifications into different parts of the car body. In this application scenario, the feeding mechanism needs to have high adaptability and flexibility. When installing the feeding mechanism of this utility model, multiple feeding tubes 2 can be installed on the frame 1, each corresponding to a different specification of rivet. The design of the rivet inlet 3 and the guide block 10 can be adjusted according to different specifications of rivets to ensure that each type of rivet can smoothly enter the corresponding feeding tube 2. The drive motor 6 can be a multi-axis motor, controlling the movement of the push rod 5 in different feeding tubes 2 through instructions from the controller 13. The sensor 12 can be installed at the bottom of each rivet outlet 4 to achieve multi-point detection. When a rivet of a certain specification is detected to be stuck or missing, the controller 13 can automatically switch to other specifications of feeding tubes 2 to continue the riveting operation, while simultaneously controlling the alarm 14 to sound an alarm, reminding the operator to handle the stuck or missing feeding tube 2. This multi-specification riveting mechanism design can significantly improve the efficiency and quality of automotive body riveting.

[0026] Specific Embodiment 5: The riveting machine feeding mechanism of this utility model can also be applied to precision assembly in the aerospace field. Assume that during the assembly process, high-precision rivets need to be fed one by one into a designated position. In this application scenario, the stability and precision requirements of the feeding mechanism are extremely high. When installing the feeding mechanism of this utility model, a high-precision linear guide rail 7 and a high-performance stepper motor 6 are required. The design of the guide block 10 and guide groove 11 needs to be very precise to ensure that each rivet can slide along a predetermined path when entering the feeding tube 2. The sensor 12 can be a high-sensitivity laser sensor to achieve accurate detection of each rivet. The controller 13 can integrate advanced algorithms and processing capabilities to ensure real-time monitoring and feedback. The alarm 14 can be a wireless alarm device installed in the operator's monitoring area so that the operator can quickly detect and handle problems. In addition, to further improve the stability of the feeding, a shock-absorbing device can be installed on the outside of the feeding tube 2 to reduce vibration during operation and ensure smooth feeding.

[0027] The riveting machine feeding mechanism of this utility model, through the above design and embodiments, not only solves the problems of unstable feeding, low efficiency, and easy jamming of existing technologies, but also improves the accuracy and stability of feeding. It is suitable for a variety of different application scenarios and has broad application prospects and practical value. Through precise guide block and guide groove design, high-precision slide rails and drive motors, and a real-time monitoring detection mechanism, the riveting feeding mechanism of this utility model can work stably and efficiently in different industrial environments, improving the overall operating efficiency of production equipment and product quality.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
