[0002] A pendulum impact testing machine is a testing device used to determine the impact resistance of materials. It is widely used in the material performance testing of industries such as metals, plastics, rubber, ceramics, and composite materials. Through pendulum impact testing, the toughness, brittleness, and fracture behavior of materials under impact loads can be evaluated, providing important basis for material research and development, quality control, and product design. The problem with existing technology is that it is inconvenient to install the test hammer. Most existing pendulum impact testing machines fix the test hammer with screws. When installing the test hammer, the weight of the test hammer is relatively large, making it difficult for a single person to install and inconvenient to operate. Utility Model Content

[0025] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 4 As shown in the figure, the present invention provides a toughness testing device for raw materials of mechanical parts, including a device body 1, a connecting rod 2 and a test hammer 3. The connecting rod 2 is fixedly connected to the top of the inner cavity of the device body 1, the test hammer 3 is disposed at the bottom of the connecting rod 2, the top of the test hammer 3 is provided with a positioning groove 4, the two sides of the top of the test hammer 3 are evenly provided with movable grooves 5, the inner cavity of the movable groove 5 is provided with a fixing mechanism 6, the front and rear sides of both sides of the connecting rod 2 are provided with fixing grooves 7 that cooperate with the fixing mechanism 6, and the top of the inner cavity of the movable groove 5 is provided with a control mechanism 8 that cooperates with the fixing mechanism 6.

[0027] refer to Figure 3 and Figure 4The fixing mechanism 6 includes a limiting plate 601 that works in conjunction with the control mechanism 8. The front and rear sides of the limiting plate 601 near the connecting rod 2 are fixedly connected to fixing blocks 602. The side of the fixing block 602 away from the limiting plate 601 passes through the test hammer 3 and extends into the inner cavity of the fixing groove 7. The side of the limiting plate 601 away from the fixing block 602 is fixedly connected to a spring 603.

[0028] The above solution is adopted: by setting the fixing mechanism 6, the test hammer 3 can be fixed, which helps the user to fix the test hammer 3 when installing it.

[0029] refer to Figure 3 and Figure 4 The control mechanism 8 includes a control plate 801, a push block 802 is fixedly connected to the top of the control plate 801, the top of the push block 802 passes through the test hammer 3 and extends to the outside of the test hammer 3, and a slanted slider 803 is provided on the rear side of the control plate 801 to cooperate with the limit plate 601.

[0030] The above solution allows for the control of the fixed mechanism 6 by setting up the control mechanism 8, making it convenient for users to operate the fixed mechanism 6.

[0031] refer to Figure 3 The side of the connecting rod 2 closest to the inner wall of the positioning groove 4 contacts the inner wall of the positioning groove 4.

[0032] The above solution is adopted: by setting the positioning groove 4, the test hammer 3 can be positioned, making it convenient for the user to fix the test hammer 3.

[0033] refer to Figure 3 The movable groove 5 has a first through hole 9 on the front and rear sides near the positioning groove 4, which is used to cooperate with the fixing block 602. The top of the movable groove 5 has a second through hole 10 that is used to cooperate with the push block 802.

[0034] By adopting the above solution, by setting the first through hole 9 and the second through hole 10, the fixing block 602 and the push block 802 can be limited respectively, making it convenient for users to use the fixing block 602 and the push block 802.

[0035] refer to Figure 3 and Figure 4 The side of the limiting plate 601 closest to the inner wall of the movable groove 5 is in contact with the inner wall of the movable groove 5, the side of the fixing block 602 closest to the inner wall of the fixing groove 7 is in contact with the inner wall of the fixing groove 7, and the side of the spring 603 furthest from the limiting plate 601 is fixedly connected to the inner wall of the movable groove 5.

[0036] The above solution is as follows: by setting the limiting plate 601, the fixed block 602 can be moved; by setting the fixed block 602 and the fixed groove 7, the test hammer 3 can be fixed; and by setting the spring 603, the limiting plate 601 can be reset.

[0037] refer to Figure 3 and Figure 4 The control plate 801 is in contact with the inner wall of the movable groove 5 on the side closest to the inner wall of the movable groove 5, the push block 802 is in contact with the inner wall of the second through hole 10 on the side closest to the inner wall of the second through hole 10, and the inclined slider 803 is fixedly connected to the limit plate 601 on the side closest to the limit plate 601.

[0038] The above scheme is adopted: by setting the control plate 801, the inclined slider 803 can be pushed to move; by setting the push block 802, the control plate 801 can be pushed to move; by setting the inclined slider 803, the limit plate 601 can be driven to compress the spring 603.

[0039] The working principle of this utility model:

[0040] In use, the user pushes the push block 802, which moves the control plate 801 and the inclined slider 803. The inclined slider 803 causes the limiting plate 601 to compress the spring 603, causing the fixing block 602 to enter the inner cavity of the movable groove 5. The user places the test hammer 3 on top of the connecting rod 2, and after the connecting rod 2 is inserted into the inner cavity of the positioning groove 4, the user releases the push block 802. The force released after the spring 603 is compressed pushes the limiting plate 601 to move in the opposite direction, and at the same time, the fixing block 602 is inserted into the inner cavity of the fixing groove 7. The limiting plate 601 pushes the control plate 801 to move in the opposite direction and reset through the inclined slider 803. After that, the user screws in the screws to complete the installation.

[0041] In summary, this toughness testing device for raw materials of mechanical parts, through the coordinated use of a fixing mechanism 6, a fixing groove 7, and a control mechanism 8, pushes the push block 802, which in turn moves the control plate 801 and the inclined slider 803. The inclined slider 803 then causes the limiting plate 601 to compress the spring 603, allowing the fixing block 602 to enter the inner cavity of the movable groove 5. This solves the problem that most existing pendulum impact testing machines fix the test hammer with screws, making installation difficult and inconvenient for a single person due to the weight of the test hammer.
