Description

Technical Field

[0001] This utility model relates to the field of rivet processing technology, and in particular to a clamping device for rivet processing. Background Technology

[0002] In the field of rivet processing, clamping devices play a crucial role, directly affecting the quality and efficiency of rivet processing. Currently, most existing rivet clamping devices on the market have certain limitations. These devices are often designed with a focus on the stable clamping of a single rivet to ensure precise rivet positioning during processing. However, this design limits the device to clamping only one rivet at a time for processing.

[0003] In actual industrial production, the demand for rivets is usually large and batch-oriented. Existing devices that can only clamp a single rivet at a time require frequent loading and unloading operations when facing large-scale production tasks, which greatly increases processing time costs and leads to low processing efficiency. Moreover, frequent operations may also increase the probability of human error, affecting the stability of product quality. Therefore, developing a clamping device for batch clamping of rivets to improve processing efficiency and product quality stability has become an urgent problem to be solved in the current rivet processing field. Utility Model Content

[0004] The main objective of this invention is to provide a clamping device for riveting, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A clamping device for riveting includes a base. A clamping platform is fixedly mounted on the base. Multiple vertically penetrating placement holes are formed at the top of the clamping platform, and rivets are placed in these holes with a clearance fit. A first chamber is formed in the middle of the clamping platform, and a clamping assembly is disposed within the first chamber. The clamping assembly includes a movable rod and a clamping plate fixedly mounted on the movable rod. One end of the movable rod slides through the left and right side walls of the clamping platform and is connected to a driving assembly. The driving assembly drives the clamping plate to slide left and right with the movable rod to clamp the rivets.

[0006] Furthermore, the clamp is arc-shaped, and a rubber pad is provided on the arc surface of the clamp facing the rivet.

[0007] Furthermore, clamping components are provided on both the front and rear sides of the rivet, and the clamping plates of the clamping components on both sides of the rivet are distributed on both sides of the rivet.

[0008] Furthermore, the driving component is a cylinder, and a fixed plate is provided on one side of the clamping table. The cylinder is horizontally fixed on the fixed plate, and the extension rod of the cylinder slides through the fixed plate and is connected to a movable rod.

[0009] Furthermore, a second chamber is provided at the bottom of the clamping platform, and the lower end of the placement hole is connected to the second chamber. An electromagnet is provided at the bottom of the second chamber.

[0010] This utility model also includes other components that enable the clamping device for rivet processing to function properly, and these devices or components all employ conventional techniques in the art. Furthermore, devices and components not limited in this utility model all employ conventional techniques in the art, such as the cylinder and electromagnet mentioned in this application. In specific implementation, appropriate equipment or component models can be selected according to the specific working scenario.

[0011] The working principle of this invention is as follows: Before placing the rivet, the electromagnet in the second chamber at the bottom of the clamping table is energized. Since the placement hole is connected to the second chamber, when the rivet is placed into the placement hole, its lower end will be subjected to the downward electromagnetic force generated by the electromagnet, accelerating the rivet's descent and positioning. After the rivet is placed, the cylinders located on both sides of the rivet extend synchronously, pushing the movable rods on both sides to slide towards each other, causing the arc-shaped clamping plates to close towards the rivet. The clamping plates on both sides simultaneously contact the outer periphery of the rivet through the rubber pads set on the arc surface. While protecting the rivet surface, the friction of the rubber pads is used to achieve batch clamping and positioning of multiple rivets, effectively preventing the rivets from rotating or shifting during processing.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. Achieved batch clamping and positioning of rivets: The movable rod is pushed synchronously by the cylinders on both sides, which drives the arc-shaped clamping plate with rubber pads to clamp multiple rivets at the same time.

[0013] 2. Improved rivet positioning efficiency: The downward electromagnetic force generated by the electromagnet accelerates the rivet's descent, shortening the positioning time.

[0014] 3. Ensures the stability of rivet processing: The friction of the rubber pad on the arc-shaped clamp effectively prevents the rivet from rotating or shifting during processing. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] Example: like Figures 1-2 As shown, a clamping device for riveting includes a base 1. A clamping platform 2 is fixedly mounted on the base 1. The top of the clamping platform 2 has multiple vertically penetrating placement holes 3, and rivets 4 are placed in the placement holes 3 with clearance fit. A first chamber 5 is formed in the middle of the clamping platform 2, and a clamping assembly is disposed in the first chamber 5. The clamping assembly includes a movable rod 8 and a clamping plate 81 fixedly mounted on the movable rod 8. One end of the movable rod 8 slides through the left and right side walls of the clamping platform 2 and is connected to a driving assembly. The driving assembly is used to drive the clamping plate 81 to slide left and right with the movable rod 8 to clamp the rivets 4.

[0020] Specifically, the clamping plate 81 is arc-shaped, and a rubber pad 82 is provided on the arc surface of the clamping plate 81 facing the rivet 4. The driving component is a cylinder 7, and a fixed plate 6 is provided on one side of the clamping table 2. The cylinder 7 is horizontally fixed on the fixed plate 6, and the telescopic rod of the cylinder 7 slides through the fixed plate 6 and is connected to a movable rod 8.

[0021] In addition, clamping components are provided on both the front and rear sides of the rivet 4, and the clamping plates 81 of the clamping components on both sides of the rivet 4 are distributed on both sides of the rivet 4. A second chamber 9 is provided at the bottom of the clamping platform 2, and the lower end of the placement hole 3 communicates with the second chamber 9. An electromagnet 10 is provided at the bottom of the second chamber 9.

[0022] The working principle of this utility model for a clamping device for rivet processing is as follows: Before placing the rivet 4, the electromagnet 10 in the second chamber 9 at the bottom of the clamping table 2 is energized. Since the placement hole 3 is connected to the second chamber 9, when the rivet 4 is placed into the placement hole 3, its lower end will be subjected to the downward electromagnetic force generated by the electromagnet 10, accelerating the rivet 4 to fall and be positioned. After the rivet 4 is placed, the cylinders 7 set on the front and rear sides of the rivet 4 are controlled to extend synchronously, pushing the movable rods 8 on both sides to slide towards each other, driving the arc-shaped clamping plates 81 to close towards the rivet 4. The clamping plates 81 on both sides simultaneously contact the outer periphery of the rivet 4 through the rubber pads 82 set on the arc surface. While protecting the surface of the rivet 4, the friction of the rubber pads 82 is used to achieve batch clamping and positioning of multiple rivets 4, effectively preventing the rivets 4 from rotating or shifting during processing.
