[0002] A spring is a mechanical part that works by utilizing elasticity. Made of elastic material, it deforms under external force and returns to its original shape after the force is removed. It is also called a "spring". They are generally made of spring steel. Springs come in a wide variety of types; based on shape, they mainly include helical springs, spiral springs, leaf springs, and irregularly shaped springs.

[0003] Existing testing and experimental mechanisms have a single testing distance, which can only test fixed distances and fails to fully utilize the performance of springs at different distances. Furthermore, they are not convenient for fixing springs of various sizes. Therefore, this utility model proposes an electronic spring fatigue testing machine to solve the above problems. Utility Model Content

[0030] There are two bonding blocks 3. The bonding block 3 located on the left side is fixedly installed on the top of the workbench 1, and the bonding block 3 located on the right side is slidably connected to the workbench 1.

[0031] There are two sets of support mechanisms and unlocking mechanisms. The support mechanism is paired with the unlocking mechanism and the bonding block 3, respectively.

[0032] The testing mechanism includes: cylinder 2 and two bonding frames 4;

[0033] Two bonding frames 4 are slidably connected to two bonding blocks 3 respectively. Cylinder 2 is fixedly installed on the top of workbench 1. The output shaft of cylinder 2 is fixedly connected to bonding block 3 located on the right side.

[0034] With the above structure, by setting a longer cylinder 2, the cylinder 2 can be adapted to springs of various lengths, making it convenient to test springs of various sizes. Furthermore, the spring can be inserted into the bonding frame 4, and then the bonding frame 4 can be controlled to bond with the bonding block 3, so that springs of various sizes can be fixed quickly and conveniently.

The support frame 6 is slidably connected to the front side of the bonding block 3. The fixing block 8 is fixedly connected to the bonding block 3. After the support frame 6 and the fixing rod 5 are engaged, the support frame 6 can connect the bonding frame 4 and the bonding block 3 to block the movement of the bonding frame 4 on the bonding block 3, so that the bonding frame 4 can be stably placed on the bonding block 3, stably bonded to the spring, and stably fixed to one end of the spring.

[0037] As a preferred embodiment of this utility model, the unlocking mechanism includes: a contact rod 9, a rotating rod 10, and a handle 11;

[0038] The bonding rod 9 is slidably connected to the front side of the bonding frame 4. The bottom of the bonding rod 9 is in slidable contact with the top of the support frame 6. The rotating rod 10 is rotatably connected to the front side of the bonding frame 4. The rotating rod 10 is in slidable contact with the bonding rod 9. The handle 11 is in slidable contact with the rotating rod 10. After the handle 11 is pressed down, the handle 11 can drive the rotating rod 10 to rotate counterclockwise, so that the rotating rod 10 can press down on the bonding rod 9, so that the bonding rod 9 can push down on the support frame 6, so that the support frame 6 can be disengaged from the fixing rod 5, and the bonding frame 4 can be unlocked, so that the bonding frame 4 can move freely on the bonding block 3 to adapt to various types of springs.

[0039] As a preferred embodiment of this utility model, a positioning block 12 is fixedly installed on the top of the support frame 6, and a plurality of positioning grooves are arranged at equal intervals on the front side of the fixing rod 5. The outer side of the positioning block 12 slides in contact with the inner wall of the positioning groove, and the top of the positioning block 12 slides in contact with the bottom of the bonding rod 9. After the positioning block 12 is inserted into the inner side of the positioning groove, the positioning block 12 can block the bonding frame 4 from moving, thereby achieving the positioning of the bonding frame 4.

[0040] As a preferred embodiment of this utility model, a vertical groove is provided on the front side of the bonding block 3, and the rear side of the support frame 6 is slidably connected to the inner wall of the vertical groove. The vertical groove is used to install the support frame 6, so that the support frame 6 can stably position the fixing rod 5.

[0041] As a preferred embodiment of this utility model, a return spring 7 is fixedly installed at the bottom of the support frame 6. The bottom of the return spring 7 is fixedly connected to the top of the fixing block 8. The return spring 7 is used to reset the support frame 6, so that the support frame 6 can automatically position the bonding frame 4.

[0042] It should be noted that the specific model of cylinder 2 used can be selected by those skilled in the art, and the above-mentioned cylinder 2 and other related technologies are all existing technologies, which will not be elaborated on in this solution.

[0043] The working principle of this utility model is as follows: By setting a relatively long cylinder 2, the cylinder 2 can be adapted to springs of various lengths, facilitating testing of springs of various sizes. Both ends of the spring can be inserted into two bonding frames 4 respectively. Then, the bonding frames 4 are controlled to bond with the bonding block 3. Simply rotate the handle 11 on the bonding frame 4. After the handle 11 is pressed down, it drives the rotating rod 10 to rotate counterclockwise, causing the rotating rod 10 to press down the bonding rod 9. This pushes the bonding rod 9 downwards, allowing the support frame 6 to disengage from the fixing rod 5, thus enabling the bonding frame 4 to be bonded. Unlocking allows the bonding frame 4 to move freely on the bonding block 3 to accommodate various types of springs. Then, releasing the support frame 6 allows it to automatically engage with the fixing rod 5. After the support frame 6 engages with the fixing rod 5, it connects the bonding frame 4 to the bonding block 3, preventing the bonding frame 4 from moving on the bonding block 3. This ensures that the bonding frame 4 is stably positioned on the bonding block 3, stably bonded to the spring, and stably fixed at one end of the spring. This allows for the fixing of springs of various sizes. Activating the cylinder 2 allows for repeated retraction and extension, enabling spring testing.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
