[0021] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0022] Please refer to Figures 1 to 5 A testing device for in-situ testing of springs includes a mounting assembly 1, a first movable base 2, a controller, and a scanning and testing assembly 3.

[0023] The first movable seat 2 is provided with an annular bracket 4. The first movable seat 2 is disposed on the mounting assembly 1 and can move along a first straight line direction perpendicular to the annular surface of the annular bracket 4 on the mounting assembly 1. The annular bracket 4 is used to be sleeved on the spring.

[0024] The scanning detection component 3 is disposed on the annular support 4, and the scanning detection component 3 can move around the annular support 4 in a ring. The controller is electrically connected to the first movable base 2 and the scanning detection component 3 respectively.

[0025] As can be seen from the above description, the beneficial effects of the present invention are as follows: by mounting component 1, an annular bracket 4 is fitted onto the spring to be tested, and the annular bracket 4 is provided with scanning component 31 detection component. The controller controls the movement of the annular bracket 4 in the first linear direction and the movement of the scanning component 31 detection component around the spring to be tested in the annular bracket 4, thereby realizing full-aspect automated scanning and testing of the spring. This can effectively avoid phenomena such as missed detection, eliminate the need for manual control of scanning, improve the accuracy of spring detection, and is convenient to arrange and easy to operate.

[0026] Furthermore, the first movable seat 2 includes an elastic connecting seat, a first movable wheel 21, and a first drive motor 22;

[0027] At least two of the elastic connecting seats are distributed along the annular edge of the ring bracket 4. Each elastic connecting seat is abutted against the mounting assembly 1 on the side away from the annular bracket 4 via the first moving wheel 21. The first drive motor 22 is connected to the first moving wheel 21 in a one-to-one correspondence. The first drive motor 22 is used to drive the first moving wheel 21 to move along the first straight line direction.

[0028] The controller is electrically connected to the first drive motor 22.

[0029] As can be seen from the above description, the first movable base 2 is composed of an elastic connecting base, a first movable wheel 21 and a first drive motor 22. The first drive motor 22 controls the first movable wheel 21 to move on the mounting assembly 1, thereby driving the entire annular bracket 4 and the scanning component 31 detection assembly on the annular bracket 4 to move up and down along the spring, automatically adjusting the scanning position. The elasticity of the elastic connecting base at different positions allows the annular bracket 4 to remain in a certain position when the first movable wheel 21 does not rotate, thereby performing the scanning action.

[0030] Furthermore, the elastic connecting seat includes a connector 23, a rocker arm 24, and a tension spring 25;

[0031] The connector 23 is connected to the annular bracket 4. The connector 23 is hinged to a rocker arm 24 on one side and the opposite side in the first straight direction. The two rocker arms 24 are connected by a tension spring 25 that is parallel to the first straight direction.

[0032] The rocker arm 24 is provided with the first moving wheel 21 at the end away from the connector 23.

[0033] As can be seen from the above description, by setting the tension spring 25 to connect the rocker arms 24 located on both sides of the connector 23, the extension and retraction of the tension spring 25 can cope with the swing of the rocker arms 24, making the movement of the first moving seat 2 more stable and flexible.

[0034] Furthermore, the annular support 4 includes a first arc-shaped guide rail 41 and a second arc-shaped guide rail 42;

[0035] The first arc-shaped guide rail 41 and the second arc-shaped guide rail 42 are connected to form a ring, and the arc length of the first arc-shaped guide rail 41 is greater than the arc length of the second arc-shaped guide rail 42.

[0036] The scanning and detection component 3 is slidably mounted on the first arc-shaped guide rail 41 or the second arc-shaped guide rail 42.

[0037] Furthermore, the annular bracket 4 includes a fixing member 43;

[0038] One end of the first arc-shaped guide rail 41 is hinged to one end of the second arc-shaped guide rail 42, and the other end of the first arc-shaped guide rail 41 is detachably connected to the other end of the second arc-shaped guide rail 42 through the fixing member 43.

[0039] As can be seen from the above description, the annular bracket 4 is composed of a first arc-shaped guide rail 41 and a second arc-shaped guide rail 42 with different arc edge lengths, so that the first moving wheel 21 on the outer wall of the annular track is not affected by the opening and closing of the track, avoiding the problem of the track being unable to open and close due to interference from the first moving wheel 21. The first arc-shaped guide rail 41 or the second arc-shaped guide rail 42 are hinged together, which can enclose the spring to be tested when the tension spring 25 is in its original position.

[0040] Furthermore, the scanning detection component 3 includes a scanning element 31 and a second movable base;

[0041] The second movable seat is provided with a slide rail 35 whose track direction is parallel to the first straight line direction, and the scanning element 31 is slidably disposed on the slide rail 35;

[0042] The second movable seat can move in a ring around the annular support 4.

[0043] As can be seen from the above description, in addition to moving around the spring to be detected on the annular bracket 4 via the second movable seat, the scanning component 31 can also be finely positioned along the slide rail 35 on the second movable seat to facilitate comprehensive detection.

[0044] Furthermore, the second movable seat includes a base 32, a second movable wheel 33, and a second drive motor 34;

[0045] The base 32 is slidably disposed on the inner ring of the annular bracket 4, the second moving wheel 33 is disposed on the base 32 and abuts against the annular bracket 4, and the second drive motor 34 is connected to the second moving wheel 33;

[0046] The scanning element 31 is disposed on the base 32, and the controller is electrically connected to the second drive motor 34.

[0047] As can be seen from the above description, the second moving wheel 33 is controlled by the second drive motor 34 to move on the inner ring of the annular bracket 4, which makes the operation stable and easy to control.

[0048] Furthermore, the scanning detection component 3 also includes a slider 36 and a third drive motor 37;

[0049] The scanning element 31 is disposed on the sliding element 36, the sliding element 36 is slidably disposed on the slide rail 35, the third drive motor 37 is connected to the sliding element 36, and the controller is electrically connected to the third drive motor 37.

[0050] As can be seen from the above description, the movement of the scanning component 31 on the slide rail 35 can be automatically controlled by the slider 36 and the third drive motor 37.

[0051] Furthermore, the mounting assembly 1 includes a mounting sleeve for fitting onto the spring;

[0052] The annular bracket 4 is disposed inside the mounting sleeve, and the annular bracket 4 is connected to the inner wall of the mounting sleeve by at least two first movable seats 2 through an interference fit.

[0053] As can be seen from the above description, by setting the mounting sleeve, the entire testing equipment can be directly placed on the spring to be tested without disassembling it, simplifying the testing preparation process and making it convenient to use.

[0054] Furthermore, the mounting sleeve includes two semi-cylindrical tube walls 11, which are detachably connected to each other.

[0055] As can be seen from the above description, the mounting sleeve consists of two semi-cylindrical tube walls 11, and is installed onto the spring by disassembling and assembling the mounting sleeve.

[0057] A testing device for in-situ testing of springs includes a mounting assembly 1, a first movable seat 2, a controller, and a scanning testing assembly 3. The first movable seat 2 is provided with an annular support 4 and is mounted on the mounting assembly 1. The first movable seat 2 can move along a first straight line direction perpendicular to the annular surface of the annular support 4. The annular support 4 is used to fit on the spring. The scanning testing assembly 3 is mounted on the annular support 4 and can move around the annular support 4. The controller is electrically connected to the first movable seat 2 and the scanning testing assembly 3.

Wherein, as Figure 2 As shown, the mounting sleeve includes two semi-cylindrical tube walls 11, which are detachably connected. Specifically, the semi-cylindrical tube walls 11 can be connected by hinges to form a complete mounting sleeve, and are connected at the opening by accessories such as clips. Similarly, the annular bracket 4 also adopts an opening and closing structure to facilitate removal from the spring to be tested.

[0059] In this embodiment, the usage process of a detection device for in-situ spring detection is as follows:

[0060] First, use the mounting sleeve to cover the spring to be tested, and at the same time, make the spring to be tested pass through the annular hole of the annular bracket 4.

[0061] Then, when the vertical position needs to be adjusted, the controller drives the first moving seat 2 so that the ring bracket 4 moves up and down along the side surface of the spring to be detected. In the horizontal direction, when different positions of the spring need to be scanned, the controller drives the scanning detection component 3 to move around the spring on the ring bracket 4.

[0062] Finally, after completing the full-range scanning inspection of the spring, disassemble the annular bracket 4 and the mounting sleeve, and remove the entire inspection equipment from the spring.

[0065] The connector 23 is connected to the annular bracket 4. A rocker arm 24 is hinged to one side and the opposite side of the connector 23 in the first linear direction. The two rocker arms 24 are connected by a tension spring 25 parallel to the first linear direction. A first moving wheel 21 is provided at the end of each rocker arm 24 away from the connector 23. The controller is electrically connected to the first drive motor 22, which drives the first moving wheel 21 to move along the first linear direction.

[0066] In this embodiment, as Figure 4 As shown, the annular bracket 4 includes a fixing member 43, a first arc-shaped guide rail 41, and a second arc-shaped guide rail 42. The first arc-shaped guide rail 41 and the second arc-shaped guide rail 42 are connected to form an annulus, and the arc length of the first arc-shaped guide rail 41 is greater than the arc length of the second arc-shaped guide rail 42.
