Description

Technical Field

[0001] This invention relates to the field of fixture loading and unloading technology, and in particular to an automatic loading and unloading system and method for a post-impact compression test fixture. Background Technology

[0002] Fiber-reinforced composites are widely used due to their high specific strength, high specific stiffness, and designability. To obtain the post-impact compression properties of specimens made of fiber-reinforced composites, it is necessary to use a standard post-impact compression test fixture to hold the specimen, preventing overall instability or local buckling during loading and thus ensuring the correct failure mode is obtained.

[0003] In related technologies, the specimens and fixtures are usually installed and disassembled manually (i.e., loading and unloading). However, this method is inefficient.

[0004] Therefore, there is an urgent need for an automatic loading and unloading system and method for post-impact compression test fixtures to solve the above-mentioned technical problems. Summary of the Invention

[0007] The post-impact compression test fixture includes a base plate, a bottom sliding plate, two corner plates, four side sliding plates, a top plate, and two top sliding plates. The bottom sliding plate is fixed to the upper side of the base plate by fasteners. The bottom edges of the two corner plates are fixed to the upper side of the base plate by fasteners. The bottom sliding plate is disposed between the sides of the two corner plates. The two side sliding plates are fixed to the inner side of the side of one corner plate by fasteners.

The four side sliding plates and the two top sliding plates are used to clamp the specimen made of fiber composite material. The top edge of the specimen abuts against the top plate, the side edges abut against the two corner plates, and the bottom edge abuts against the bottom sliding plate.

[0008] The positioning mechanism is used to position the post-impact compression test fixture by abutting against the base plate, the bottom sliding plate, the corner plate, the side sliding plate, the top plate, and the top sliding plate.

[0011] In the second aspect, the embodiments of the present application provide an automatic loading and unloading method of a post-impact compression test fixture, which is applied to the automatic loading and unloading system in any of the above embodiments and comprises the following steps:

[0012] When the test piece is disassembled, the following steps are performed:

[0013] Step S11: The mechanical arm drives the gripper to move the post-impact compression test fixture holding the test piece from a first preset position to a second preset position;

[0014] Step S12: The first moving baffle is used to translate the post-impact compression test fixture to a position abutting against the fixed baffle;

[0017] Step S15: The loading and unloading mechanism is used to disassemble the top plate and the top sliding plate; during the disassembly process, the distance between the two top sliding plates is increased by horizontal movement of the loading and unloading mechanism;

[0018] Step S16: After the top plate and the top sliding plate are disassembled, the mechanical arm drives the adsorption tool to adsorb the test piece, so as to realize the disassembly of the test piece; during the disassembly process, the distance between two adjacent side sliding plates is increased by horizontal movement of the mechanical arm;

[0019] Step S17: After the test piece is disassembled, the mechanical arm drives the blowing tool to blow the bottom sliding plate;

[0020] When the test piece is installed, the following steps are performed:

[0021] Step S21: The mechanical arm drives the adsorption tool to place a new test piece between the side sliding plates with increased distance;

[0022] Step S22, installing the top plate and the top sliding plate to the top of the test piece by the loading and unloading mechanism, so that the test piece is placed between the top sliding plates with increased distance;
