Description

Technical Field

[0001] This utility model relates to the field of spring testing technology, specifically a spring fatigue testing device. Background Technology

[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. Fatigue level is an important indicator of a spring's performance, and fatigue testing is required during spring production and use.

[0003] Application number 202422217424.5 discloses a spring fatigue testing machine. This machine uses a control device to control a lower limit device, a testing device, and an upper limit device. The lower limit device acts as a bottom limit, the testing device performs fatigue detection, and the upper limit device acts as a top limit. It includes an operating table and a control device, a lower limit device, a testing device, and an upper limit device. The control device, lower limit device, and testing device are all mounted on the operating table, and the upper limit device is mounted on the testing device. The control device provides control, the lower limit device provides bottom limit, the testing device performs fatigue detection, and the upper limit device provides top limit. However, when performing compression tests on the spring, the spring is exposed. During the test, the spring may break due to fatigue, and the broken spring fragments can easily fly, posing a safety hazard and potentially injuring the operator. Therefore, this utility model proposes a spring fatigue testing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a spring fatigue testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spring fatigue testing device, comprising a support base, a support plate fixedly mounted on the support base, an electric telescopic rod fixedly mounted on the support plate, a movable seat fixedly mounted at the output end of the electric telescopic rod, a fixed seat fixedly mounted on the support base, transparent baffles symmetrically arranged on the support base, and a driving component for driving the two transparent baffles to move on the support base.

[0006] Preferably, the drive assembly includes two sliding grooves formed on the support base and a bidirectional threaded rod rotatably disposed in the support base, and a sliding plate is slidably connected in each of the two sliding grooves.

[0007] Preferably, the two sliding plates are symmetrically arranged on the bidirectional threaded rod, and the bidirectional threaded rod is threadedly connected to the sliding plates. The upper ends of the two sliding plates are respectively fixedly connected to two transparent baffles.

[0008] Preferably, a sliding strip is fixedly connected to the lower end of the transparent partition, and a limiting groove for the sliding strip to slide is provided on the support base.

[0009] Preferably, both the lower end of the movable seat and the upper end of the fixed seat are provided with placement grooves, and a central column is fixedly installed in the placement grooves.

[0010] Preferably, one end of the bidirectional threaded rod extends out of the support base and is fixedly connected to a connecting column.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By rotating the connecting column, the connecting column drives the bidirectional threaded rod to rotate, causing the sliding plate to move along the sliding groove. This drives the transparent baffle to cover the spring under test, preventing it from breaking and splashing, thus ensuring safety. The electric telescopic rod drives the moving seat to move back and forth, working in conjunction with the fixed seat and the central column to stably perform compression tests on the spring under test, ensuring accurate detection. The sliding strip cooperates with the limit groove to ensure smooth movement of the transparent baffle. The overall structure is simple and easy to operate. 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. 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] Please see Figures 1 to 4 This utility model provides a technical solution: a spring fatigue testing device, including a support base 1, a support plate 2 fixedly mounted on the support base 1, an electric telescopic rod 3 fixedly mounted on the support plate 2, a movable seat 4 fixedly mounted at the output end of the electric telescopic rod 3, a fixed seat 5 fixedly mounted on the support base 1, transparent baffles 8 symmetrically arranged on the support base 1, and a driving component for driving the two transparent baffles 8 to move. By rotating the connecting column 14, the connecting column 14 drives the bidirectional threaded rod 13 to rotate, causing the sliding plate 12 to move along the sliding groove 9, driving the transparent baffles 8 to cover the spring 7 to be tested, preventing it from breaking and splashing, and ensuring safety; the electric telescopic rod 3 drives the movable seat 4 to move back and forth, and together with the fixed seat 5 and the central column 6, it can stably perform compression testing on the spring 7 to be tested, ensuring accurate testing; the sliding strip 11 cooperates with the limiting groove 10 to ensure that the transparent baffles 8 move smoothly. The overall structure is simple and easy to operate.

[0020] like Figure 3 as well as Figure 4 As shown, the driving assembly includes two sliding grooves 9 formed on the support base 1 and a bidirectional threaded rod 13 rotatably disposed within the support base 1. Sliding plates 12 are slidably connected in both sliding grooves 9. The two sliding plates 12 are symmetrically arranged on the bidirectional threaded rod 13. The bidirectional threaded rod 13 is threadedly connected to the sliding plates 12. The upper ends of the two sliding plates 12 are respectively fixedly connected to two transparent partition plates 8. The lower ends of the transparent partition plates 8 are fixedly connected to sliding strips 11. The support base 1 has a limiting groove 10 for sliding strips 11. Since the two sliding plates 12 are threadedly connected to the bidirectional threaded rod 13, under the rotation of the bidirectional threaded rod 13, the two sliding plates 12 will move closer to each other, causing the two transparent partition plates 8 to move closer to each other, and finally cover the outside of the spring 7 under test, preventing the spring 7 under test from breaking and splashing during the test.

[0021] like Figure 3 As shown, both the lower end of the movable seat 4 and the upper end of the fixed seat 5 are provided with placement grooves. A central column 6 is fixedly installed in the placement groove. The placement groove facilitates the limiting of the spring 7 to be tested. One end of the bidirectional threaded rod 13 extends out of the support base 1 and is fixedly connected to the connecting column 14. Rotating the connecting column 14 causes the bidirectional threaded rod 13 to rotate.

[0022] In actual use, the spring to be tested 7 is placed on the central column 6, and the spring to be tested 7 is positioned between the movable seat 4 and the fixed seat 5. The operator rotates the connecting column 14, which drives the bidirectional threaded rod 13 to rotate. Since both sliding plates 12 are threadedly connected to the bidirectional threaded rod 13, under the rotation of the bidirectional threaded rod 13, the two sliding plates 12 will move closer to each other, causing the two transparent baffles 8 to move closer to each other, and finally cover the outside of the spring to be tested 7 to prevent the spring to be tested 7 from breaking and splashing during the test. After that, the electric telescopic rod 3 is started, and the electric telescopic rod 3 drives the movable seat 4 to move back and forth. When the movable seat 4 moves downward, it compresses the spring to be tested 7 located below it. When the movable seat 4 moves upward, the spring to be tested 7 returns to its original shape under its own elasticity. Through this reciprocating compression process, the fatigue test of the spring is completed. During the test, the operator can clearly observe the state of the spring to be tested 7 through the transparent baffles 8.

[0023] 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.
