[0002] The splicing method for the outer frame and sash of thermally broken aluminum doors and windows, and the outward opening windows of curtain walls, etc., adopts the corner assembly process, also known as corner collision. Generally, corner brackets are placed into the profile cavity and a special machine, namely a corner assembly machine or corner assembly production line, is used. The corner brackets are pressed along the slot of the corner bracket by a cutting tool, leaving a groove on the outside of the profile. The profiles are then spliced ​​together to form a right angle.

An outer positioning head 1005 is mounted on the outer positioning plate 1003, and the height position of the outer positioning head 1005 on the outer positioning plate 1003 can be changed. The clamping power component 1002 can drive the outer positioning head 1005 to move towards the inner positioning head 901.

The pressure block 13 is located above the worktable 8 and is used to drive the pressure block 13 to press the profile corner onto the worktable 8, thereby improving the stability during processing.

[0037] In this embodiment, a control component is also included, which is controlled by a numerical control system. The numerical control system is connected to each power component to control each working step of the device, thereby reducing the labor intensity of the workers and improving the automation of the equipment and the efficiency of processing.

[0038] Working principle: First, the profile corner with the corner bracket installed is placed on the worktable 8. The height of the outer positioning head 1005 and the inner positioning head 901 is adjusted according to the size and height of the profile. Then, the corresponding corner assembly cutter 601 is moved up and down by different threaded shafts 607. The height of the movement can be freely adjusted. After the position of the corner assembly cutter 601 is determined, the locking power component 701 drives the swing arm 703 to rotate the locking shaft 704. The rotation of the locking shaft 704 temporarily fixes the relative position of the corner assembly cutter handle 609 and the cutter holder 602. Then, the profile corner is fixed on the worktable 8 by the inner positioning component 9, the outer positioning component 10 and the pressure block 13. The left infeed unit 1 and the right infeed unit 2 are driven to move simultaneously by the infeed moving component 5 to complete the corner assembly processing.
