[0041] A driving strip 38 is provided between each group of two fixed blocks 33 on the flip frame 9, a second gear 39 is fixedly sleeved on the middle of the third rotating rod 34, and teeth meshing with the second gear 39 are provided on the driving strip 38, and the driving strip 38 is in an "L" shape.

The inner diameter of the second arc groove 45 is 1.2 times the inner diameter of the first arc groove 44. One end of the insertion rod 43 is movably inserted into one of the first arc grooves 44. During the rotation of the flip frame 9, the sliding of the insertion rod 43 in the second arc groove 45 can drive the driving bar 38 to move on the flip frame 9, and the third rotating rod 34 is driven to rotate through the second gear 39, thereby automatically driving the limit plate 36 to rotate and insert it into the flip frame 9 to limit the aluminum profile. When the insertion rod 43 slides in the first arc groove 44, the limit plate 36 can be automatically rotated out of the flip frame 9, so that the feeding and unloading operations can be carried out normally on the flip frame 9.

[0042] The implementation principle of the compression testing device for aluminum profiles in the embodiment of the present invention is as follows: the motors 7 on the two support frames 3 are started to drive the two sets of conveyor belts 6 to rotate, and the conveyor belt 6 on the left side conveys the aluminum profile to be tested toward the direction of the testing platform 1. When the aluminum profile on the conveyor belt 6 on the left side is delivered to the flip frame 9, the first cylinder 12 can be started to drive the L-shaped bar 15 to move toward the side close to the conveyor belt 6 on the left side, so as to drive the rotating shaft 8 and the flip frame 9 to rotate in the clockwise direction as a whole, and the flip frame 9 drives the insertion rod 43 from the first arc groove 44. The turning plate 26 is moved to the second arc groove 45 to pull the connecting plate 40 to move on the guide rod 41 to the side away from the turning frame 9, and the third rotating rod 34 is pulled to rotate by the second gear 39 to rotate the limiting plate 36 into the turning frame 9, and the aluminum profile is limited in the turning frame 9 to prevent the aluminum profile from falling from the turning frame 9 when the turning frame 9 drives the aluminum profile to rotate. When the turning frame 9 drives the aluminum profile to rotate to a vertical state, the turning frame 9 stops rotating, and the second cylinder 25 is started to drive the penetration at both ends of the lifting plate 26 The through rod 27 slides in the guide groove 28 of the two driving plates 18, pulling the two driving plates 18 to move synchronously toward the middle on the cross bar 17, and drives the detection plate 21 to move and squeeze onto the aluminum profile in the flip frame 9 through the L-shaped rod 20, and performs a compression test on the aluminum profile, and the test result is displayed on the display 2. After the test, the second cylinder 25 drives the lifting plate 26, and the two detection plates 21 move in the opposite direction to reset, and then the first cylinder 12 continues to drive the L-shaped bar 15 to move toward the side close to the left conveyor belt 6 , and continues to drive the flip frame 9 to rotate in the clockwise direction. When the flip frame 9 rotates to the right conveyor belt 6, the insertion rod 43 slides from the second arc groove 45 to the first arc groove 44, and automatically rotates the limit plate 36 out of the flip frame 9, and releases the limit on the aluminum profile in the flip frame 9. At this time, the conveyor belt 6 rotating on the right can smoothly bring the inspected aluminum profile out of the flip frame 9 for automatic unloading. In this way, automatic inspection of the aluminum profile can be realized, the operation is more labor-saving and convenient, and the inspection efficiency is higher.

[0043] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
