The bottom end of the buffer spring 8 is fixedly connected to the bottom of the second mounting seats 5 through the fixing blocks 9. Next, circular grooves 10 are equidistantly carved into the top of the assembly plate 2. The diameter of the circular grooves 10 decreases from the outside to the inside. Rubber strip seals of different sizes and lengths are placed in the circular grooves 10 on the top of the assembly plate 2. When the assembly plate 2 is frequently impacted by the impact head of the impact testing equipment, the rubber strip seals in the circular grooves 10 can be tested. This allows for uniform impact resistance performance testing of rubber strip seals of different sizes and lengths, greatly improving work efficiency. Under the action of the buffer spring 8, the damage caused to the assembly plate 2 by the impact testing equipment can be reduced, vibration and noise can be alleviated, impact force and stress can be reduced, thereby reducing fatigue damage to the assembly plate 2 and extending its service life.

[0027] Example 2

[0028] like Figure 1-4 As shown, a tooling for testing the impact resistance of a seal according to an embodiment of the present invention includes a base 1 and an assembly plate 2. The assembly plate 2 is disposed above the base 1, and an ejector plate 3 is provided on the top of the assembly plate 2. First mounting seats 4 are fixedly connected to both sides of the base 1, and second mounting seats 5 are fixedly connected to both sides of the assembly plate 2. Guide rods 6 are fixedly connected to the top of the first mounting seats 4, and the guide rods 6 penetrate through the top of the second mounting seats 5. The ejector plate 3 includes a lifting plate 11, a first semi-circular strip 12, and a second semi-circular strip 13. The first semi-circular strip 12 is equidistantly disposed on the front side of the top of the lifting plate 11, and the second semi-circular strip 13 is equidistantly disposed on the front side of the top of the lifting plate 11. On the rear side of the top of the lifting plate 11, semi-circular openings are symmetrically provided on the bottom side of the inner wall of the circular groove 10. The first semi-circular strip 12 and the second semi-circular strip 13 are respectively movably fitted into the inner wall of the semi-circular opening and are flush with the top opening of the semi-circular opening. After the impact test is completed, the ejector plate 3 can be raised, so that the first semi-circular strip 12 and the second semi-circular strip 13 on the top of the ejector plate 3 extend out of the top of the semi-circular opening on the bottom side of the inner wall of the circular groove 10. This allows the first semi-circular strip 12 and the second semi-circular strip 13 to remove the assembled rubber seal, eliminating the need for workers to pry the rubber seal out bit by bit.

[0029] Example 3

[0030] like Figure 1-4 As shown, a tooling for testing the anti-collision performance of a seal according to an embodiment of the present invention includes a base 1 and an assembly plate 2. The assembly plate 2 is disposed above the base 1, and an ejector plate 3 is provided on the top of the assembly plate 2. First mounting seats 4 are fixedly connected to both sides of the base 1, and second mounting seats 5 are fixedly connected to both sides of the assembly plate 2. Guide rods 6 are fixedly connected to the top of the first mounting seats 4, and the guide rods 6 penetrate the top of the second mounting seats 5. An installation cavity 14 is provided in the wall cavity of the base 1. A servo motor 15 is fixedly connected to the right side of the inner wall of the installation cavity 14.

When the assembly plate 2 is frequently impacted by the impact head of the impact testing equipment, the rubber strip seals in the circular groove 10 can be tested. After the impact test is completed, the servo motor 15 is started. The output shaft of the servo motor 15 drives the rotating shaft 16 to rotate, so that the cam 17 on the outer wall of the rotating shaft 16 lifts the movable ejector rod 18 upward, so that the ejector rod 18 drives the lifting plate 11 to rise, and the first semi-circular strip 12 and the second semi-circular strip 13 on the top of the lifting plate 11 automatically extend out of the semi-circular opening on the bottom side of the inner wall of the circular groove 10, which can realize automated material ejection and picking operation. Under the action of the return spring 20, after the protrusion of the cam 17 leaves the bottom end of the ejector rod, the ejector rod 18 in the rising state will automatically descend and reset.
