[0025] A hardness testing frame for aluminum alloy doors and windows comprises a support 1 and a testing frame assembly 2 fixed on the top of the support 1 and used for testing the hardness of the aluminum alloy doors and windows.

[0026] In this implementation scheme: In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the current existing supporting mechanism is only for the detection of aluminum alloy doors and windows of fixed sizes, and its overall flexibility is poor, and it is unable to limit aluminum alloys of different sizes", combined with actual use, this problem is obviously a real problem that exists and is difficult to solve. Therefore, in order to solve this technical problem, a limiting component 3 is added on this basis.

[0029] The limiting assembly 3 includes a U-shaped support 31 fixed on the top of the support 1, and a rotating rod 32 is arranged between the left and right ends of the U-shaped support 31 through a bearing, and a pair of guide rods 33 for guiding.

[0030] In an optional embodiment, the left and right ends of the rotating rod 32 are respectively provided with external threads with opposite thread directions, and the two ends of the rotating rod 32 are respectively screwed with a left support 34 and a right support 35, and the tops of the left support 34 and the right support 35 are respectively fixed with a left U-shaped frame 37 and a right U-shaped frame 38, and the left support 34 and the right support 35 are both sleeved on the guide rod 33, and the left support 34 and the right support 35 both slide left and right on the guide rod 33, and a reduction motor 36 is installed at the right end of the U-shaped support 31, and the rotor of the reduction motor 36 is fixedly connected to the rotating rod 32.

[0031] In this embodiment: the reduction motor 36 is driven to drive the rotating rod 32 to rotate. Since the threads at both ends of the rotating rod 32 are in opposite directions, and the left support 34 and the right support 35 are respectively screwed on the threads in different directions at both ends of the rotating rod 32, the rotation of the rotating rod 32 drives the left support 34 and the right support 35 to move in opposite directions, thereby driving the left U-shaped frame 37 and the right U-shaped frame 38 to move in opposite directions.

[0034] Working principle of this utility model:

[0035] According to the aluminum alloy doors and windows of different sizes, the reduction motor 36 is driven to drive the rotating rod 32 to rotate. Since the threads at both ends of the rotating rod 32 are in opposite directions, and the left support 34 and the right support 35 are respectively screwed on the threads in different directions at both ends of the rotating rod 32, the rotation of the rotating rod 32 drives the left support 34 and the right support 35 to move in opposite directions, and then drives the left U-shaped frame 37 and the right U-shaped frame 38 to move in opposite directions, thereby limiting the aluminum alloy doors and windows of different sizes, and then drives the cylinder 23 to push the moving plate 25 to move downward, and the sliding sleeve 24 on the moving plate 25 slides on the sliding rod 21 to perform a guiding role, and the moving plate 25 drives the pressure rod 27 downward to perform hardness testing on the aluminum alloy doors and windows.
