[0002] An impact tester is a material testing device that applies impact test force to a specimen to perform an impact test. The pendulum impact tester is the most common impact tester. When in use, several specimens of the same shape and size are first processed, one of which is embedded and installed on the specimen table, and then the pendulum is lifted to a position. At this time, the pendulum release device is combined with the fixed hook, and the fixed hook is released through the pendulum release device, thereby releasing the pendulum from a high position to impact the specimen and complete the test.
[0003] Before using a traditional pendulum impact tester, the user usually uses a centering hammer to center the pendulum. This method generally requires multiple tests for test accuracy. When placing the sample on the sample table, it is difficult to place it in the same position as the last test position, resulting in test errors. Therefore, a centering device for an impact tester is proposed to solve this problem. Utility Model Content

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] like Figures 1 to 5 As shown, the utility model provides a centering device for an impact testing machine, including a machine base 1, which is a part of the impact testing machine. A centering device body 2 is arranged on one side of the top of the inner cavity of the machine base 1. In order to reduce the friction generated by the impact test and generate friction resistance, the centering device body 2 is designed as a stepped shape as a whole, which is thin at the top and thick at the bottom. A centering auxiliary component is arranged between the machine base 1 and the centering device body 2. The centering auxiliary component includes a movable plate 3 arranged on one side of the centering device body 2. The movable plate 3 is a square plate structure. The top and bottom ends of the movable plate 3 are symmetrically fixedly connected with two limit rods 5. The limit rods 5 are L-shaped structures. The centering device body 2 is limited between the four limit rods 5 to limit the installation position. Fixed plates 6 are fixedly connected on both sides of the movable plate 3. Strip plates 7 are slidably and interlaced on one side of the two fixed plates 6. The strip plates 7 can move laterally relative to the fixed plates 6. One end of the two strip plates 7 is fixedly connected with a clamping plate 8, and the clamping plate 8 is a T-shaped structure.
[0023] Three arc grooves 11 are equidistantly provided on the inner side of the clamping plate 8, and extrusion wheels 12 are installed inside the three arc grooves 11. The extrusion wheels 12 can rotate in the arc grooves 11, and the outer surface of the extrusion wheels 12 fits with the inner wall of the centering device body 2. After the centering device body 2 is installed on one side of the movable plate 3, after the four limit rods 5 limit the installation position of the centering device body 2, the extrusion force of the extrusion wheel 12 on the centering device body 2 can effectively realize the installation and fixation of the centering device body 2, and can ensure the convenience of disassembly and assembly of the centering device body 2. Two elastic ropes 13 are symmetrically fixedly connected to one side of the clamping plate 8, and one end of the two elastic ropes 13 are fixedly connected to the inner side of the fixed plate 6. The elastic potential energy of the elastic ropes 13 is utilized to realize that the clamping plate 8 can automatically return to its initial position when not subjected to lateral force.
[0024] A through hole 4 is provided in the middle of the movable plate 3, which corresponds to the centering hole of the centering device body 2, and the inner diameter of the through hole 4 is slightly larger than the inner diameter of the centering hole of the centering device body 2. A connecting plate 9 is fixedly connected to the outer side of the movable plate 3, and an adjusting rod 10 is connected to the middle part of the outer side of the connecting plate 9 through a bearing. The adjusting rod 10 is fixedly connected to the inner ring of the bearing, and the connecting plate 9 is fixedly connected to the outer ring of the bearing, ensuring that the adjusting rod 10 will not drive the connecting plate 9 to rotate synchronously when rotating. A cross plate 14 is fixedly connected to one side of the top of the inner cavity of the base 1, and the adjusting rod 10 is threadedly connected to the middle part of the cross plate 14. The threaded connection between the adjusting rod 10 and the cross plate 14 is used to achieve that the adjusting rod 10 can move laterally relative to the cross plate 14 while rotating. Two guide rods 15 are symmetrically fixedly connected to the inner side of the cross plate 14, and one end of the two guide rods 15 passes through the connecting plate 9 and is fixedly connected to the limited block. The two guide rods 15 are used to effectively ensure the stability of related components such as the centering auxiliary component during lateral movement.
[0025] The working principle and process of this utility model are as follows:
[0026] When in use, first embed the sample used for the impact test in the relevant position on the machine base 1, and then the user can rotate the adjusting rod 10. While rotating, the adjusting rod 10 can simultaneously move laterally in the direction of the sample. The movement of the adjusting rod 10 drives the connecting plate 9 and the movable plate 3 to move synchronously. The movement of the movable plate 3 drives the clamped and fixed centering device body 2 to move in the direction of the sample. After the centering device body 2 moves to a certain position, the user can use the position between the centering hole on the centering device body 2 and the sample to adjust the swing position on the impact tester until the centering work of the impact tester is completed.
