Description

Technical field:

[0001] The utility model relates to the technical field of corner assembly machines, in particular to a quick locking device for corner assembly knives. Background technology:

[0002] The cornering knife is one of the most important parts of the cornering machine. The cornering knife is installed on the punching and riveting mechanism through the knife holder. Driven by the punching and riveting mechanism, the cornering knife performs punching and riveting on the profile, thereby causing local cold deformation of the profile. The deformed part is inserted into the angle code to achieve connection, thereby completing the cornering.

[0003] Different specifications of profiles correspond to different angle codes and punching and riveting positions, so the cornering knife is required to have an adjustable height function. The existing technology provides a feasible solution for the height adjustment of the cornering knife. For example, a Chinese patent discloses a magnetic cornering knife holder, and the authorization announcement number is: CN216828292U. This solution uses the principle of magnets to detachably adsorb the cornering knife on the knife holder, which is convenient for the vertical adjustment of the cornering knife, and then cooperates with the corresponding thread locking to finally fix the cornering knife. Although the existing technology provides a feasible and quick adjustment solution for the height adjustment of the cornering knife, the locking of the cornering knife still uses thread locking. Thread locking has the advantage of being relatively reliable, but thread locking is relatively time-consuming and labor-intensive to disassemble and assemble, and cannot match the magnetic quick adjustment solution of the cornering knife, which restricts the overall adjustment efficiency of the cornering knife, and thus affects the working efficiency of the cornering machine.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility model content:
