Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of spring fatigue testing machines, and in particular, to a multi-purpose and multi-station synchronous spring fatigue testing machine. Background Art
[0002] In the fields of modern industrial production and scientific research, as a basic component widely used in many industries such as machinery, automobiles, and electronics, the quality and performance reliability of springs are crucial. The fatigue performance of springs is one of the key indicators for evaluating spring quality. Therefore, spring fatigue testing machines play an indispensable role in the process of spring production and quality inspection. With the diversified development of industrial production, the demand for spring types and specifications is increasing day by day. Traditional spring fatigue testing machines are gradually difficult to meet the needs of actual production and testing in terms of functions and efficiency. In this context, the research and development of multi-station synchronous spring fatigue testing machines has important practical significance, aiming to improve the efficiency of spring fatigue testing and the versatility of equipment.
[0003] Most of the existing spring fatigue testing machines have relatively simple structures. Usually, a fixed frame constitutes the main framework, and a set of transmission mechanisms are equipped on the frame to provide the power required for testing. The test platform is relatively fixed, and simple fixtures are set on it, which can only fix and test a certain type of spring.
[0004] However, the prominent problem of existing spring fatigue testing machines is that they cannot simultaneously take into account the testing of multiple types of springs on the same device. In the process of actual production and inspection, it is often necessary to conduct fatigue tests on various types of springs such as extension springs, compression springs, and torsion springs. However, most of the existing devices are single-purpose and can only test one type of spring. If multiple types of springs need to be tested, multiple different testing machines need to be purchased, and the equipment needs to be frequently replaced during the operation process, which reduces the testing efficiency. Therefore, a multi-purpose and multi-station synchronous spring fatigue testing machine is proposed to solve the above problems. Summary of the Invention
[0005] In order to make up for the above deficiencies, the present invention provides a multi-purpose and multi-station synchronous spring fatigue testing machine, aiming to improve the problem that most of the existing devices in the prior art are single-purpose and can only test one type of spring, and the equipment needs to be frequently replaced during the operation process.
[0006] In order to achieve the above object, the present invention adopts the following technical solutions:
[0007] A multi-purpose multi-station synchronous spring fatigue testing machine, including a front panel. A plurality of chutes are provided inside the front panel. A tension spring testing movable tooling is arranged on one side of the front panel. A tension spring testing fixed tooling is fixedly connected to one side of the front panel. A compression spring testing movable tooling is arranged on one side of the front panel. A compression spring testing fixed tooling is fixedly connected to one side of the front panel. A torsion spring testing movable tooling is arranged on one side of the front panel. A torsion spring testing fixed tooling is fixedly connected to one side of the front panel. The tension spring testing movable tooling, the compression spring testing movable tooling and the torsion spring testing movable tooling are respectively slidably connected inside the plurality of chutes. A rear panel is fixedly connected to the other side of the front panel.
[0008] As a further description of the above technical solution:
[0009] A plurality of tooling sliders are arranged on one side of the rear panel. The plurality of tooling sliders are respectively connected to the tension spring testing movable tooling, the compression spring testing movable tooling and the torsion spring testing movable tooling.
[0010] As a further description of the above technical solution:
[0011] A transmission rod is rotatably connected to one side of each of the plurality of tooling sliders. A fixing frame is arranged on one side of the rear panel.
[0012] As a further description of the above technical solution:
[0013] A main slider is slidably connected to one side of the rear panel. The main slider is connected to the tooling slider.
[0014] As a further description of the above technical solution:
[0015] A motor is fixedly connected to one side of the rear panel. The output end of the motor is connected to the main slider.
[0016] As a further description of the above technical solution:
[0017] A connecting frame is arranged on one side of the rear panel. The transmission rod is connected to the connecting frame.
[0018] The present invention has the following beneficial effects:
[0019] In the present invention, by driving the main slider, the tooling slider and other structures to move by means of the motor, the different testing movable toolings are slid, realizing the effect that one device can simultaneously test multiple types of springs at multiple stations, solving the problem that most of the existing devices are used alone, and one device can only test one type of spring, and the device needs to be frequently replaced during the operation process, thereby improving the testing efficiency.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0026] Refer to Figures 1 - 3, an embodiment provided by the present invention: a multi-purpose multi-station synchronous spring fatigue testing machine, including a front panel 1. A plurality of chutes 3 are provided inside the front panel 1. A tension spring testing movable tooling 2 is arranged on one side of the front panel 1. A tension spring testing fixed tooling 4 is fixedly connected to one side of the front panel 1. A compression spring testing movable tooling 5 is arranged on one side of the front panel 1. A compression spring testing fixed tooling 6 is fixedly connected to one side of the front panel 1. A torsion spring testing movable tooling 7 is arranged on one side of the front panel 1. A torsion spring testing fixed tooling 8 is fixedly connected to one side of the front panel 1. The tension spring testing movable tooling 2, the compression spring testing movable tooling 5 and the torsion spring testing movable tooling 7 are respectively slidably connected inside the plurality of chutes 3, providing a sliding path for the testing tooling. The up and down movement of the tooling slider 10 enables the testing tooling to slide up and down in the chute 3, simulating the forces encountered by the spring during operation. A rear panel 9 is fixedly connected to the other side of the front panel 1. A plurality of tooling sliders 10 are arranged on one side of the rear panel 9. The plurality of tooling sliders 10 are respectively connected to the tension spring testing movable tooling 2, the compression spring testing movable tooling 5 and the torsion spring testing movable tooling 7. Through the tension spring testing movable tooling 2, the compression spring testing movable tooling 5 and the torsion spring testing movable tooling 7, these toolings cooperate with the spring to simulate stretching, compression and torsion operations. A transmission rod 11 is rotatably connected to one side of each of the plurality of tooling sliders 10. The function of the transmission rod 11 is to convert the left and right movement of the main slider 12 into the up and down movement of the tooling slider 10, ensuring that the tooling slider 10 slides along a specific direction. A fixed frame 13 is arranged on one side of the rear panel 9. A main slider 12 is slidably connected to one side of the rear panel 9. The main slider 12 is connected to the tooling slider 10. The left and right movement of the main slider 12 drives the movement of the tooling slider 10. In this way, the movement of the main slider 12 is converted into a mechanical force on the tooling slider 10. A motor 15 is fixedly connected to one side of the rear panel 9. The output end of the motor 15 is connected to the main slider 12. A connecting frame 14 is arranged on one side of the rear panel 9. The transmission rod 11 is connected to the connecting frame 14.
[0027] Working principle: After the motor 15 starts, the output end drives the main slider 12 to move left and right on one side of the rear panel 9. The main slider 12 is connected to multiple tooling sliders 10. During the movement of the main slider 12, it will drive the tooling sliders 10 to move together. One side of the tooling slider 10 is rotatably connected to a transmission rod 11, and the transmission rod 11 is connected to the connecting frame 14. The left and right movement of the main slider 12 applies a force in the bevel cutting direction to the tooling slider 10 through the transmission rod 11, so that the tooling slider 10 moves up and down on the rear panel 9. A plurality of chutes 3 are provided inside the front panel 1. When the tooling slider 10 moves up and down, it will drive the tension spring test movable tooling 2, the compression spring test movable tooling 5 and the torsion spring test movable tooling 7 connected thereto to slide up and down in the chute 3 of the front panel 1. When performing the spring fatigue test, the tension spring is installed between the tension spring test movable tooling 2 and the tension spring test fixed tooling 4, the compression spring is installed between the compression spring test movable tooling 5 and the compression spring test fixed tooling 6, and the torsion spring is installed between the torsion spring test movable tooling 7 and the torsion spring test fixed tooling 8. As the corresponding movable tooling slides up and down, repeated tensile, compressive or torsional forces are applied to the spring to simulate the stress conditions of the spring in actual use, so as to test the fatigue performance of the spring.
[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
