[0027] See also Figure 2-3 In order to enable the detection machine to perform impact resistance detection on different positions of building materials, the adjustment mechanism 6 in this embodiment includes a first motor 601 fixed to the left side of the detection chamber 2, a first screw rod 602 is fixed to the outer side of the output shaft of the first motor 601, a first rod sleeve 603 is threadedly connected to the outer surface of the first screw rod 602, a positioning rod 604 is fixed between the left and right side walls of the inner cavity of the detection chamber 2, and a positioning sleeve 605 is fixed to the upper surface of the first rod sleeve 603.

[0028] The positioning sleeve 605 is slidably connected to the outer surface of the positioning rod 604, and the positioning rod 604 is located above the first screw rod 602. When the first rod sleeve 603 moves, the positioning sleeve 605 starts to move. At this time, the positioning sleeve 605 slides on the outer surface of the positioning rod 604, and the upper surface of the horizontal plate 3 is fixed to the lower surface of the first rod sleeve 603.

[0029] See also Figure 4In order to ensure that the building materials will not shift during the inspection process, the positioning mechanism 8 in this embodiment includes a positioning bin 801 fixed to the lower surface of the workbench 1, and a second motor 802 is fixed to the inner bottom wall of the positioning bin 801, and a second screw rod 803 is fixed to the outer side of the output shaft of the second motor 802, and a second rod sleeve 804 is threadedly connected to the outer surface of the second screw rod 803.

[0033] The standard parts used in this application can all be purchased from the market, and special-shaped parts can be customized according to the instructions and drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets and welding in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0034] If the present application discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously not possible to use an one-piece molding process).

[0035] The working principle of the above embodiment is:

[0036] (1) When it is necessary to use the impact resistance testing machine to perform impact resistance testing on building materials, first place the building materials to be tested on the material placement seat 7. After the materials are placed, start the second motor 802 to drive the second screw rod 803 to start rotating. The second rod sleeve 804 moves downward with the rotation of the second screw rod 803. The movement of the second rod sleeve 804 drives the moving plate 805, the connecting rod 806, the positioning plate 807 and the clamping member 808 to move downward. As the clamping member 808 moves, when the clamping member 808 fixes the building materials, the second motor 802 is turned off.

[0037] (2) Then, the hydraulic cylinder 4 is started, and the hydraulic cylinder 4 drives the detection head 5 to move downward, and an impact force is applied to the building materials through the detection head 5. At the same time, the impact force applied by the detection head 5 to the building materials is adjusted by adjusting the output pressure of the external hydraulic pump. The damage of the building materials is observed by using impact forces of different sizes, and the maximum impact force that the building materials can withstand is obtained. When it is necessary to detect different positions of the building materials, the first motor 601 is started at this time, driving the first screw rod 602 to start rotating. The first rod sleeve 603 moves left or right with the rotation of the first screw rod 602. The movement of the first rod sleeve 603 drives the horizontal plate 3, the hydraulic cylinder 4 and the detection head 5 to move simultaneously, thereby realizing the adjustment of the detection position, and being able to detect different positions of the building materials.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
