Description

Technical Field

[0001] The utility model relates to the technical field of riveting machines, in particular to a desktop riveting machine. Background Art

[0002] The principle of the riveting machine (also known as the riveting machine, rotary riveting machine, riveting machine, etc.) is mainly based on the cold rolling technology, which uses rotation and pressure to complete the assembly. It is mainly used for riveting work of solid rivets or hollow rivets.

[0003] Specifically, the riveting machine presses rivets into objects to form a fastened connection by adjusting parameters such as pressure, time and temperature. When working, the pushing mechanism on the riveting machine pushes the rivet from the material table to the pushing table, and the pushing table pushes the rivet to the riveting table through the pushing mechanism. Then the staff penetrates the riveted parts with the rivets and adjusts the pressure, bolt diameter and depth of the riveting machine according to actual needs. When the riveting machine reaches the appropriate pressure, the rivet will be pressed into the object to complete the fixed connection.

[0004] In the process of implementing the solution, the inventors found that the following problems in the prior art have not been well solved: in traditional technology, in order to avoid misalignment between the workpiece and the rivet during riveting, the staff will use a press to press the workpiece, and then remove the workpiece from the riveting table after the riveting is completed. Since the surface of the press is relatively smooth and the lower pressing end of the riveting machine easily contacts the press when pressing down, the press and the workpiece will be displaced during pressing, which will result in a certain number of defective products in the riveting process, which brings inconvenience to the riveting process.
