[0002] The impact resistance of plate-shaped specimens is one of the key indicators for evaluating the reliability, safety, and service life of materials. The falling ball impact test, a classic method for evaluating the impact resistance of materials, assesses the material's impact strength by releasing an impact ball of specified mass from a predetermined height onto a plate-shaped specimen below it.

[0006] Furthermore, the plate positioning assembly includes a positioning tray and a magnetic pin, and the positioning tray has multiple insertion holes.
[0007] Furthermore, magnets are fixedly connected to both the bottom end of the magnetic pin and the inside of the socket.
[0008] Furthermore, the multiple ball receiving ports are arranged in a linear array on the guide tube, and the lifting device is specifically a linear slide.
[0009] Furthermore, the positioning groove is a V-shaped groove, and the ball baffle is fixedly connected to the lifting platform.
[0010] Furthermore, the cylinder is fixedly connected to the lifting platform, and the push rod is fixedly connected to the piston rod of the cylinder.
[0011] Furthermore, the lifting platform has a sliding groove, and the lower end of the push rod extends into the sliding groove.
[0012] Compared with the prior art, the advantages of this utility model are as follows: it can adapt to impact testing of plate-shaped specimens of different sizes, and can adapt to drop ball testing of different heights. It is easy to adjust and has relatively high testing accuracy. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Example:
[0020] Please see Figure 1-4 A plate-shaped specimen drop ball impact test fixture includes a base 1 and a support 2. Plate positioning components 3 are provided on both sides of the base 1. A guide tube 4 and a lifting device 5 are detachably connected to the support 2. The guide tube 4 is provided with multiple ball receiving ports 401. A lifting platform 6 is fixedly connected to the moving platform of the lifting device 5. The lifting platform 6 is provided with a positioning groove 601. Ball blocking plates 7 are arranged parallel to each other on the lifting platform 6. A ball pushing component is provided on the lifting platform 6 between the two ball blocking plates 7. The ball pushing component includes a cylinder 801 and a push rod 802.
[0021] The plate positioning assembly 3 includes a positioning tray 301 and a magnetic pin 302. The positioning tray 301 is used to position and support the plate-shaped specimen to be tested. Multiple insertion holes 303 are opened on the positioning tray 301. The insertion holes 303 are used to position and insert the magnetic pin 302. According to the size of the plate-shaped specimen to be tested, the magnetic pin 302 is installed in a suitable insertion hole 303. Magnets are fixedly connected to the bottom end of the magnetic pin 302 and inside the insertion hole 303. After the magnetic pin 302 is placed, it is fixed by magnetic attraction.
[0022] Multiple ball receiving ports 401 are arranged in a linear array on the guide tube 4. The ball receiving ports 401 are used for small balls for drop testing. The lifting device 5 is specifically a linear slide table. The lifting platform 6 is driven to rise and fall by the lifting device 5, so that the small balls can be sent to different heights for testing.
[0023] The positioning groove 601 is a V-shaped groove. The ball baffle 7 is fixedly connected to the lifting platform 6. The ball baffle 7 can limit the feeding and pushing of the small ball.
[0024] Cylinder 801 is fixedly connected to the lifting platform 6, and push rod 802 is fixedly connected to the piston rod of cylinder 801. Cylinder 801 is used to drive push rod 802 to push the ball down for testing. The lifting platform 6 has a sliding groove 602, and the lower end of push rod 802 extends into the sliding groove 602. The sliding groove 602 makes way for the push rod 802 to push.
[0025] The working principle of this utility model is as follows: When using this utility model, the test piece to be tested is placed along the positioning plate 301 and the magnetic pin 302. The small ball for impact testing is placed in the positioning groove 601 along the ball baffle 7. Then, the lifting device 5 drives the lifting platform 6 to rise to the ball receiving port 401 at the required test height (which can be positioned by a sensor). Then, the piston rod of the cylinder 801 extends, and the push rod 802 pushes the small ball into the ball receiving port 401 and falls along the guide tube 4 onto the plate-shaped test piece to be tested. The test piece is observed to see if it is broken or has cracks. If the above situations occur, the test is unqualified.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
