Description

Technical Field

[0001] This utility model relates to the field of rivet feeding technology, and in particular to a quenching feeding device for automotive beam rivets. Background Technology

[0002] The automotive frame is a core load-bearing component in the overall structure of a vehicle, and its performance directly affects the safe and stable operation of the vehicle under various working conditions. As a key fastener connecting the various components of the automotive frame, the quality and performance of rivets have a decisive impact on the reliability of the overall frame structure. During long-term vehicle operation, the frame needs to continuously withstand complex forces from the vehicle body, cargo, and road surface. This requires rivets to have extremely high strength to resist tensile and shear loads, appropriate toughness to avoid brittle fracture, and good fatigue resistance to cope with long-term repeated stress. To ensure that rivets meet the above performance requirements, quenching is an indispensable part of the production process. Quenching treatment, which involves heating the rivets at high temperatures and then rapidly cooling them, can effectively change their internal metallographic structure, thereby significantly improving their hardness and strength.

[0003] However, the effectiveness of the quenching process depends not only on the process parameters of temperature control and cooling rate, but also on the feeding method of the rivets during quenching. Traditional rivet quenching feeding methods rely heavily on manual operation. Manual feeding is not only labor-intensive, but also makes it difficult to ensure the stability of the feeding speed and the positioning accuracy of the rivets at the quenching station. This can easily lead to differences in quenching time and heating uniformity among different rivets, thus affecting the consistency of product quality. With the continuous development of the automotive manufacturing industry, highly automated quenching feeding devices have become the key to improving rivet production efficiency and ensuring product quality. They can reduce manual intervention and lower labor costs. However, the accumulation and compression of rivets in the feed hopper, along with their entanglement and blockage, can cause the feeding track and feed port to be jammed, interrupting the feeding process and preventing continuous supply to subsequent processes. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a quenching feeding device for automotive frame rivets, which aims to improve the problem in the prior art where rivets accumulate and squeeze in the feed hopper, become entangled and form blockages, causing the feeding track and feed inlet to be stuck, the feeding process to be interrupted, and the inability to continuously supply materials to subsequent processes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quenching and feeding device for automotive frame rivets, comprising a base plate, a support platform fixedly connected to the top left side of the base plate, a vibration mechanism provided in the middle of the support platform for orderly arrangement of rivets, a feeding mechanism provided at the top of the base plate for conveying rivets, the vibration mechanism comprising a feeding hopper, the outer wall of the feeding hopper fixedly connected to the middle of the support platform, a supporting plate slidably connected to the bottom of the feeding hopper, multiple springs fixedly connected to the bottom of the supporting plate, a protective block fixedly connected to the bottom of the springs, the bottom of the protective block fixedly connected to the middle of the support platform, a support column fixedly connected to the bottom center of the supporting plate, a power assembly provided in the middle of the support platform, and a discharge assembly provided at the bottom of the supporting plate.

[0006] As a further description of the above technical solution:

[0007] The feeding mechanism includes two support plates, the bottom of which is fixedly connected to the top of the base plate. The top of the support plate has multiple grooves. The front right end of the rear support plate is fixedly connected to a support plate, and the top of the support plate is fixedly connected to a motor. The output end of the motor is fixedly connected to a short plate. The front left end of the rear support plate is rotatably connected to a short plate. The tops of the short plates are rotatably connected to a support plate, and the top of the support plate is fixedly connected to multiple brackets. Each bracket has a large rivet on its top.

[0008] As a further description of the above technical solution:

[0009] The power assembly includes a motor, the rear side of which is fixedly connected to the middle of the inner rear end of the support platform. A disk is fixedly connected to the output end of the motor, and a disk is rotatably connected to the middle of the inner front end of the support platform.

[0010] As a further description of the above technical solution:

[0011] A third disk is rotatably connected between adjacent disks one and two. A connecting column is fixedly connected to the top of disk three, and the top of the connecting column is slidably connected to the inner side of the supporting column.

[0012] As a further description of the above technical solution:

[0013] The discharge assembly includes a discharge box, the bottom of which is fixedly connected to the top right side of the protective block, and a limit plate is fixedly connected to the top right side of the discharge box.

[0014] As a further description of the above technical solution:

[0015] A U-shaped plate is fixedly connected to the top left side of the discharge box, and the outer wall of the U-shaped plate is slidably connected to the bottom right side of the support plate.

[0016] As a further description of the above technical solution:

[0017] The base plate is fixedly connected to baffles on both the front and rear sides of the top, and a quenching device is fixedly connected to the right side of the top of the base plate.

[0018] As a further description of the above technical solution:

[0019] A connecting strip is fixedly connected to the top left side of each of the two support plates, and a connecting plate is fixedly connected to the top right side of the support plate.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the rivet is placed into the feed hopper from the top, and then the disc is rotated by the motor. At this time, the support plate moves up and down on the bottom of the inner side of the feed hopper. Since the bottom of the support plate is fixedly connected with a spring, it provides a buffer for the up and down movement of the support plate, extending the service life of the equipment. At the same time, due to the lifting and lowering of the support plate, the U-shaped plate will lift and lower inside the support plate, bringing the rivet into the discharge box, reducing the problem of feeding stagnation caused by rivet accumulation.

[0022] 2. In this utility model, when the rivet is transmitted to a support plate through the connecting strip, the first short plate is rotated by the second motor, which in turn drives the second short plate to rotate synchronously, thereby moving the third support plate. After the large rivet is supported by the bracket, it is transmitted to the groove and engaged. The next rivet is received through another groove, and so on. This avoids the time interval caused by waiting for the receiving in the traditional transmission, thus improving the transmission efficiency. Attached Figure Description

Baffles 5 are fixedly connected to the front and rear sides of the top of the bottom plate 1. A quenching device 6 is fixedly connected to the top right side of the bottom plate 1.

[0036] Specifically, the bottom of the discharge box 2071 is fixedly connected to the top right side of the protective block 204 to ensure its stability during operation. A limiting plate 2072 is fixedly connected to the top right side of the discharge box 2071. The function of the limiting plate 2072 is to limit the movement range of the rivets during the discharge process, ensuring the accuracy and orderliness of the discharge process. A U-shaped plate 2073 is fixedly connected to the top left side of the discharge box 2071, which helps to better guide the conveying direction of the rivets. The outer wall of the U-shaped plate 2073 is connected to the bottom right side of the receiving plate 202 by a sliding connection, allowing the U-shaped plate 2073 to move to adapt to the needs of different working conditions.

[0037] Please see the appendix Figure 2 - Appendix Figure 4A connecting strip 7 is fixedly connected to the top left side of each of the two support plates 301, and a connecting plate 8 is fixedly connected to the top right side of the support plate 301. The power assembly 206 includes a motor 2061. The rear side of the motor 2061 is fixedly connected to the middle of the inner rear end of the support platform 4. A disc 2062 is fixedly connected to the output end of the motor 2061. A disc 2063 is rotatably connected to the middle of the inner front end of the support platform 4. A disc 2064 is rotatably connected between adjacent discs 2062 and 2063. A connecting column 2065 is fixedly connected to the top of the disc 2064. The top of the connecting column 2065 is slidably connected to the inner side of the support column 205.

[0038] Specifically, connecting strips 7 are fixedly connected to the top left side of both support plates 301 to ensure the transmission path of the structure. Connecting plates 8 are fixedly connected to the top right side of support plates 301 to further enhance the support and transmission capacity of the structure. The power assembly 206 includes a motor 2061. The rear part of the motor 2061 is fixedly connected to the middle of the inner rear end of the support platform 4 to ensure that the motor will not be displaced during operation. The output end of the motor 2061 is fixedly connected to a disc 2062 to transmit power. A disc 2063 is rotatably installed at the middle of the inner front end of the support platform 4. A disc 3064 is rotatably installed between the adjacent discs 2062 and 2063 to form an eccentric wheel structure. The top of the connecting column 2065 is slidably connected to the inner part of the support column 205 to ensure the stability of the connection and achieve the vibration effect.

[0039] Working principle: The rivet is inserted into the feed hopper 201 from the top. Then, the motor 2061 drives the rotation of the disc 2062. At this time, the disc 2064 rotates as an eccentric wheel under the action of the disc 2063 on the disc 2062. Since the connecting column 2065 is inside the support column 205, it will move the support plate 202 up and down on the inner bottom of the feed hopper 201. Because the bottom of the support plate 202 is fixedly connected to the spring 203, it provides a buffer for the up and down movement of the support plate 202, reducing the impact. This reduces rigid impacts during mechanical movement, minimizes component wear, and extends equipment lifespan. Simultaneously, the lifting and lowering of the support plate 202 causes the U-shaped plate 2073 to move within the support plate 202, carrying the rivets into the discharge box 2071. The rivets are then positioned in a preset orientation and discharged from the right side of the discharge box 2071, reducing feeding stagnation caused by rivet accumulation. This also creates conditions for subsequent directional conveying, avoiding directional deviations caused by uneven vibration during feeding, ensuring uniform rivet posture before entering the next process, and reducing conveying problems caused by inconsistent postures.

[0040] When the rivet is transmitted to the support plate 301 via the connecting strip 7, the short plate 305 is rotated by the motor 304, which in turn drives the short plate 306 to rotate synchronously. This, in turn, moves the support plate 307. After the large rivet 309 is supported by the bracket 308, it is conveyed to the groove 302 and engaged. The next rivet is then received by another groove 302, and this cycle continues until the rivet is finally conveyed by the connecting plate 8 to the quenching device 6 for quenching. Compared with manual handling, this method avoids rivet falling and shifting due to unstable support, effectively ensuring the stability of the conveying process and reducing damage to rivets caused by collisions and drops. The cyclical reception of rivets in the groove 302 achieves seamless rivet conveying, avoiding the time interval caused by waiting for reception in traditional conveying, improving conveying efficiency, and meeting the needs of continuous production of large batches of rivets. This provides a continuous and stable material supply for the subsequent quenching process.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
