This ensures the consistency of test conditions and improves the accuracy of the test. At the same time, it can prevent dust and dirt and other impurities from adhering to the impact head or other key components of the testing device, which would affect the normal operation of the device.

[0032] like Figures 1-2 As shown, the present invention proposes a repetitive impact-resistant testing device, comprising a connecting platform 1, a support column 2 disposed at the bottom of the connecting platform 1, a base plate 3 disposed at the bottom of the support column 2, a support column 4 disposed at the top of the connecting platform 1, a top plate 5 disposed at the top of the support column 4, a testing mechanism, a moving positioning mechanism, and an airbag 607.

[0033] The testing mechanism is located on top of the connecting platform 1 and is used to blow away dust and impurities from the surface of the material to be tested during the testing process.

[0034] The mobile positioning mechanism is located on the top of the base plate 3 and is used to move the material to be tested to the area to be tested and fix it.

[0035] An installation box 608 is slidably provided on the outer side of the airbag 607. The bottom of the installation box 608 is connected to the top of the vehicle panel. An air blowing pipe 610 is provided at the bottom of the airbag 607. The airbag 607 is compressed to generate airflow under the drive of the detection mechanism. The end of the air blowing pipe 610 away from the airbag 607 points to the material to be tested. The airflow blows through the air blowing pipe 610 to the material to be tested to blow away the debris.

[0036] The detection mechanism includes a cylinder 601, a push rod 602, a pressure detector 603, an impact head 604, and a cleaning assembly.

A display screen 605 is located on the side of the pressure detector to record the reading of the pressure detector 603 in real time for easy observation.

[0037] Example 2

[0038] like Figures 3-5 As shown, this utility model proposes a repetitive impact-resistant testing device. Compared with Embodiment 1, this embodiment details the structure of the mobile positioning mechanism.

[0039] The mobile positioning mechanism includes a rotary moving component, a sliding component, and a positioning component. The sliding component is located on the top of the base plate 3 and is used for lateral movement control detection points. The rotary moving component is located on top of the sliding moving component and is used for longitudinal movement control detection points. The positioning component is located on the side of the rotary moving component and is used for positioning the adjusted rotary moving component. The sliding component includes a slide table 702, a straight slide rail 701, and a straight slide rail 716. The straight slide rail 701 is located at the top edge of the base plate 3. The slide table 702 is slidably mounted on the straight slide rail 701. The straight slide rail 716 is located on the top side of the base plate 3 away from the straight slide rail 701. A slide table 715 is slidably mounted on the straight slide rail 716. A fixing frame 714 is located on the side of the slide table 715. A rod 719 is slidably mounted on the end of the fixing frame 714 away from the slide table 715. A spring 718 is located on the outer side of the rod 719. The straight slide rail 716... Positioning holes 717 are provided, and multiple positioning holes 717 are evenly arranged on the second straight slide rail 716. The inner diameter of the positioning hole 717 is the same as the diameter of the insertion rod 719. Therefore, the positioning hole 717 and the insertion rod 719 can be connected together. When movement is required, the insertion rod 719 is pulled up to disengage from the positioning hole 717, and then the second slide table 715 is slid. The second slide table 715 drives the first slide table 702 to slide synchronously. When it moves to the area to be detected, the insertion rod 719 is released. Under the action of the third spring 718, the insertion rod 719 is inserted into the positioning hole 717 at that location, thereby fixing the second slide table 715. The rotary moving assembly includes a threaded rod 704, a rotating ring 706, a mounting platform 709, and mounting rods 710. The threaded rod 704 is rotatably mounted inside the slide table 702. The rotating ring 706 is located at the end of the threaded rod 704. The mounting platform 709 is threaded onto the outside of the threaded rod 704. The mounting rods 710 are located on the outside of the mounting platform 709. Four mounting rods 710 are arranged in a ring around the mounting platform 709. Each mounting rod 710 has a sliding groove. A clamping plate 711 is slidably mounted on the mounting rod 710. A telescopic tube 712 is provided on the side of the clamping plate 711. The outside of the telescopic tube 712 is provided with... A second spring 713 is provided. The end of the telescopic tube 712 away from the clamping plate 711 is connected to the end of the mounting rod 710. The side of the clamping plate 711 away from the telescopic tube 712 is clamped with the building material 8. Rotating the rotating ring 706 causes the threaded rod 704 to rotate. When the threaded rod 704 rotates, it causes the mounting platform 709 to move longitudinally on the threaded rod 704, thereby causing the building material 8 to move. The building material 8 is clamped to the top of the mounting platform 709 by four clamping plates 711. Due to the action of the second spring 713 and the telescopic tube 712, building materials 8 of any size can be clamped and fixed.The positioning assembly includes a positioning wheel 705, a connecting rod 703, a locking block 707, and a spring 708. The positioning wheel 705 is located on the outside of the threaded rod 704, and the outside of the positioning wheel 705 has multiple notches. The locking block 707 is engaged with the outside of the positioning wheel 705. The shape of the locking block 707 is the same as the notches, so the locking block 707 can cooperate with the positioning wheel 705 to fix the position of the threaded rod 704. The spring 708 is located on the side of the locking block 707 away from the positioning wheel 705, and the connecting rod 703 is located at the end of the spring 708 away from the locking block 707. The bottom of the connecting rod 703 is connected to the side of the base plate 3. When the threaded rod 704 rotates and moves the building material 8 to the area to be inspected, the rotating ring 706 stops rotating. At this time, the locking block 707 is engaged with the notch under the action of the spring 708, thereby fixing the position of the threaded rod 704 and ensuring that the building material 8 will not move during inspection.

[0040] In summary, when using this utility model, the building material 8 is inserted between the four clamping plates 711. The four clamping plates 711, under the action of spring 713 and telescopic tube 712, hold the building material 8 in place. Then, the insertion rod 719 is pulled up to disengage from the positioning hole 717. The sliding table 715 is slidable, and the sliding table 715 drives the sliding table 702 to slide synchronously via the threaded rod 704. When it moves to the area to be inspected, the insertion rod 719 is released, and under the action of spring 718, it is inserted into the positioning hole 717 at that location, thus fixing the sliding table 715. After the lateral position adjustment is completed, the rotating ring 706 is rotated. The rotating ring 706 drives the threaded rod 704 to rotate. When the threaded rod 704 rotates, it drives the mounting platform 709 to move longitudinally on the threaded rod 704, thereby driving the building material 8 to move longitudinally. After the adjustment is completed, the rotation of the rotating ring 706 is stopped. 06. At this time, the locking block 707, under the action of the spring 708, engages with the notch at the location of the positioning wheel 705, thereby fixing the position of the threaded rod 704 and ensuring that the building board 8 will not move during the inspection. After aligning the inspection area of ​​the building board 8 directly below the cylinder 601, the cylinder 601 is activated. The cylinder 601 drives the push rod 602 to move, and the push rod 602 drives the pressing plate 606 to move downward. When the pressing plate 606 moves, it squeezes the airbag 607 to generate airflow. The airflow blows away impurities and dust above the inspection area of ​​the building board 8 through the air blowing pipe 610. Then, the push rod 602 continues to move downward until the impact head 604 contacts the surface of the building board 8 to generate impact force. The degree of impact force is displayed on the display screen 605 through the pressure detector 603. This process is repeated to perform repeated impact inspections.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
