Description

Technical Field

[0001] The utility model relates to the technical field of riveting machines, in particular to a riveting device for a luggage cart. Background Art

[0002] Luggage carts are mainly used to haul people's luggage and parcels. During the assembly process of the luggage cart, it needs to be riveted by a riveting machine. By inserting the rivet into the workpiece to be connected and then using the pressure of the riveting machine to deform the rivet, two or more workpieces are firmly connected together. During the riveting process, the workpiece to be connected first needs to be placed on the lower support of the riveting machine. Then, the rivet feeding mechanism feeds the rivet into the riveting position. Under the action of the punch, the rivet is pushed to the upper surface of the workpiece and begins to apply pressure. As the punch continues to push, the rivet foot part will pierce the upper workpiece and penetrate the lower workpiece. At this time, the material of the lower workpiece will flow into the riveting die, and the rivet leg will bend to form a lock. After the punch stroke is completed, the riveting is completed and the two workpieces are firmly connected together.

[0003] During riveting operations on luggage carts, if abnormal riveting conditions such as insufficient rivet torque and loose rivets are encountered, these problems are usually accompanied by significant fluctuations in the riveting pressure value, which may manifest as a sudden decrease or abnormal increase in pressure. However, traditional riveting machines lack the ability to detect riveting pressure in real time, which makes it impossible to quickly identify and reject defective products.

[0004] In order to solve the above problems, this application proposes a luggage cart riveting device. Utility Model Content

Elastic piston portions 32 are inserted into the two gas cylinder bodies 31. The lower support 4 is installed at the top ends of the two elastic piston portions 32. The bottom end of the gas cylinder body 31 is connected to an air guide tube 33 communicating with its interior. The end of the air guide tube 33 away from the gas cylinder body 31 passes through the riveting workbench 2. One end is arranged toward the lower support 4, the blowing part 5 is connected to one end of the two air guide tubes 33 facing the lower support 4, a one-way valve 34 is installed on the air guide tube 33, the elastic piston part 32 includes a movable rod 321, the two movable rods 321 slide through the top of the two air cylinder bodies 31 respectively, the lower support 4 is installed on the top of the two movable rods 321, the movable rod 321 is sleeved with a spring 322 located between the air cylinder body 31 and the lower support 4, the two ends of the spring 322 are respectively connected to the air cylinder body 31 and the lower support 4, and the bottom end of the movable rod 321 is installed with a piston body 323 arranged in the air cylinder body 31 and slidably connected to its inner wall.

[0025] In this embodiment, a blowing member 5 is installed at the end of the elastic air cylinder member 3, which is arranged toward the lower support 4 and blows air thereto. The blowing member 5 includes a blowing pipe 51, which is laterally connected to one end of the two air guide pipes 33 facing the lower support 4. The blowing pipe 51 is connected to the air guide pipe 33, and a plurality of air holes 52 arranged toward the lower support 4 are opened on the blowing pipe 51.

[0026] In this embodiment, a pressure warning component 6 is installed on the riveting workbench 2 and is located below the lower support 4. The pressure warning component 6 includes an assembly block 61. The other end of the riveting workbench 2 is provided with an assembly groove located below the lower support 4. The assembly block 61 is installed in the assembly groove. A pressure warning part 62 is installed on the assembly block 61. The pressure warning part 62 includes a pressure sensor 621, an alarm 622 and a controller 623. The pressure sensor 621 is installed on the top of the assembly block 61 and is located below the lower support 4.

The pressure sensor 621 and the alarm 622 are both communicatively connected to the controller 623.

[0027] It should be noted that: the workpiece to be riveted can be fixed on the lower support 4, and then the workpiece on the lower support 4 can be punched by the punch head 7, and the nail foot of the rivet pierces the upper workpiece and penetrates into the lower workpiece to fix the two workpieces together. At the same time, under the elastic action of the spring 322, the piston body 323 can be pushed downward in the cylinder body 31 by the movable rod 321, and the lower support 4 also moves downward. When the lower support 4 moves downward, it can press the pressure sensor 621, and the pressure sensor 621 can measure the workpiece after being pressurized.

This structure introduces a pressure early warning part 6 to monitor the pressure changes in the riveting process in real time, and can immediately detect abnormal conditions such as insufficient rivet torque or loose rivet body, effectively avoiding the flow of defective products into the next process due to the lack of real-time monitoring capability of the traditional riveting machine 1.

[0028] It should be further explained that when the lower support 4 moves downward and pushes the piston body 323 to move in the cylinder body 31 through the movable rod 321, the gas in the cylinder body 31 can be guided to the air blowing pipe 51 along the air guide pipe 33, and the gas can be blown to the lower support 4 and the workpiece through the air hole 52 opened on the air blowing pipe 51, thereby cleaning the dust on the workpiece. When the workpiece is riveted, under the elastic action of the spring 322, the lower support 4 can drive the piston body 323 at the bottom end of the movable rod 321 to return to its original position. Since a one-way valve 34 is provided on the air guide pipe 33, it can effectively prevent external air from entering it through the air hole 52 opened on the air blowing pipe 51, and external air can enter the air guide pipe 33 in one direction through the one-way valve 34 to perform the next exhaust action. This structure can realize the function of cleaning the dust on the surface of the workpiece during the riveting process.

[0029] In a specific embodiment, a through hole is opened at the top of the cylinder body 31 and communicates with the interior thereof, so that external air can enter therein through the top thereof when the piston body 323 moves downward.
