[0001] The utility model belongs to the field of aluminum door and window corner assembling machines, and specifically relates to a new type of door and window corner assembling machine. Background Technique

[0002] Aluminum doors and windows are a common type of doors and windows in our daily life. Most of their shapes are rectangular or square. During their production and manufacturing process, they are mostly assembled by splicing. Four sections of window frames are spliced together to form doors and windows, and this process is called corner assembling. Most of the market uses corner assembling machines to perform the corner assembling operation of aluminum doors and windows; when using traditional synchronous corner assembling machines, workers need to first press the two sections of window frames to be corner assembled against the chamfer fixing blocks manually, and then drive the chamfering module to perform chamfering operations on the two sections of window frames through cylinders or hydraulic cylinders. Finally, the chamfered parts of the two sections of window frames are fixed and pressed by the riveting machines on both sides and above. After completion, the two ends can be released manually, and then the operation can be continued on the other side; Patent No. CN220329786U authorized and announced by the State Intellectual Property Office on January 12, 2024: "A Synchronous Aluminum Door and Window Corner Assembling Machine", which discloses a corner assembling machine that can limit the position of aluminum alloy doors and windows during corner assembling.
