Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and sashes.

Aluminum alloy doors and windows include doors and windows with aluminum alloy as the base material of the load-bearing rods and wood and plastic composites, or aluminum-wood composite doors and windows or aluminum-plastic composite doors and windows for short. The quality of aluminum alloy doors and windows can be roughly judged from the selection of raw materials, aluminum surface treatment and internal processing quality, and the price of aluminum alloy doors and windows. In the production process of aluminum alloy doors and windows, quality inspection is an indispensable process in production, and the sealing problem between the window sash glass and the window frame is an important factor in measuring the quality of high watertightness aluminum alloy doors and windows.

[0021] 1. The present invention provides a vacuum suction cup at the bottom of the hydraulic rod mechanism, and under the action of the vacuum pump, it is convenient to directly adsorb the doors and windows so as to push them into the device housing. Under the action of the positioning frame and the first spring, the doors and windows are pushed to the support cushion frame and stabilized.

Under the connection action of the second spring 30, the second connecting plate 24 enables the hydraulic rod mechanism 3 to cooperate with the vacuum suction cup 6 to drive the inspected doors and windows to rise for removal. The second connecting plate 24 automatically drives the pressure plate 27 to rise, so that a negative pressure state is formed in the smoke storage tank 26, thereby realizing the effect of automatically drawing back the smoke used for inspection, and finally the doors and windows can be removed.
