Therefore, accurately testing the elastic strength of springs is crucial for product quality control.

[0003] While commonly used spring elastic strength testing equipment can meet basic testing needs, it often presents certain operational inconveniences and limitations for spring structures of different specifications. Furthermore, its overall testing effect and accuracy for springs are not ideal. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling for testing the elastic strength of springs. This tooling structure can conveniently clamp and fix springs of different specifications, while further improving the overall testing effect and accuracy of the springs. It has high flexibility and applicability.

[0005] The technical solution adopted by this utility model to solve the above problems is:

[0006] A tooling for testing the elastic strength of a spring includes a fixed base and two sets of connecting seats that slide in opposite directions, driven by a driving component located below the fixed base. Each connecting seat has a connecting rod with two sets of sliders slidably mounted on it. Each slider has a locking component and a second connecting seat. The second connecting seat has a connecting component for spring locking. A force detection module is located between the sliders and the second connecting seat. The fixed base has a control module connected to both the driving component and the force detection module.

[0007] Preferably, the size of the second connecting seat is adapted to the side size of the slider corresponding to the connecting side, and multiple sets of the force detection modules acting between the slider and the second connecting seat are arranged at intervals along the peripheral edge of the second connecting seat.

[0008] Preferably, a cavity is formed between the multiple force detection modules and the corresponding side of the slider, and a convex plate is provided on the corresponding side of the slider in the cavity, and a through hole is provided on the convex plate.

[0009] Preferably, the connector includes a pin plate and multiple sets of protrusions on its wall surface.

[0016] Compared with the prior art, this utility model has the following advantages and effects:

[0017] This utility model relates to a tooling for testing the elastic strength of springs. Compared to commonly available spring testing machines, this tooling utilizes a drive mechanism on the fixed base to drive the connecting seat to slide in opposite directions. Combined with the structural design of the slider on the connecting rod, its second connecting seat, and the connection method between the connecting member and the connecting seat, it can adapt to the clamping and fixing of springs of different specifications and perform corresponding testing processes without affecting the normal testing process. This further improves the ease of operation, flexibility, and applicability of this spring elastic strength testing tooling. Furthermore, the connection method between the connecting member on the second connecting seat and the corresponding spring wires at both ends of the spring, and the connection method between the force detection module and the slider, ensures the stability of the connection and testing with the spring while simultaneously improving the spring's elastic strength. Two sets of force detection modules on two sets of sliders at both ends perform a synchronous detection process of the magnitude of the force at corresponding positions, which can further improve the detection effect and accuracy of the spring as a whole. The stability of the spring during the detection process can be judged by the parameter changes of the force detection modules at corresponding positions at both ends of the spring. When the parameters detected by the force detection modules are uniform and change at the same amplitude, the best testing effect of the spring can be achieved. When the parameter fluctuations of the force detection modules at corresponding positions at both ends of the spring are large, it indicates that there is an abnormality in the spring or the connection point with the connecting parts. This allows operators to check and adjust the abnormality in a timely manner, reduce the degree of further damage to the spring, and further improve the detection effect and detection stability of this spring elastic strength testing fixture to meet different application needs.

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0023] See Figure 1-2 This embodiment relates to a tooling for testing the elastic strength of a spring 100, including a fixed base 1 and two sets of connecting seats 3 that slide in opposite directions, driven by a driving component 2 located below the fixed base 1. The connecting seats 3 are provided with connecting rods 4, and two sets of sliders 5 are slidably arranged on the connecting rods 4. The sliders 5 are provided with locking components 51 and second connecting seats 6. The second connecting seats 6 are provided with connecting components 7 for locking the spring 100. A force detection module 8 is provided between the sliders 5 and the second connecting seats 6. The fixed base 1 is provided with a control module that is connected to the driving component 2 and the force detection module 8 respectively.

[0024] Specifically in this embodiment, such as Figure 1 and Figure 2The overall structure of the spring 100 elastic strength testing fixture shown in the figure includes a control module that can be configured as a controller, operation panel, and control buttons to control the corresponding components. At the same time, multiple slots 10 on the corresponding positions of the fixed base 1 facilitate wiring connections. Thus, under the operation and control of the control module, the driving component 2 can be driven and the parameters of the force detection module 8 can be viewed and adjusted. Specifically, the driving component 2 can be driven by a ball screw, and the corresponding driving structure is set. It includes a lead screw shaft 21 rotatably arranged below the fixed base 1, a drive motor 22 connected to one end of the lead screw shaft 21 on one side of the fixed base 1, and a main slider 23 that slides on the lead screw shaft 21 and is connected to the connecting seat 3 above it through a through groove 11 opened at the corresponding position of the fixed base 1. The lead screw shaft 21 adopts a double-rotation structure, and the main sliders 23 arranged on it are arranged in two groups and respectively placed at both ends of the lead screw shaft 21 and respectively connected to the connecting seats 3 arranged at the corresponding positions above the fixed base 1. The force detection module 8 can adopt a conventional sensor for pressure and tension detection, and the corresponding connection process with the slider 5 and the second connecting seat 6 is carried out. During use, the control module on the fixed base 1 can be operated to control the rotation of the lead screw shaft 21 driven by the drive motor 22 in the drive component 2. Under the action of the two sets of main sliders 23 on the lead screw shaft 21, the two sets of connecting seats 3 above the fixed base 1 slide towards each other. Specifically, the two sets of connecting seats 3 can be moved at a corresponding distance according to the length of the spring 100 to be tested. At the same time, the slider 5 on the sliding connecting rod 4 can be moved to both ends of the spring 100, and the connecting piece 7 on the second connecting seat 6 connected to one side of the slider 5 can be used to fix the spring 100 at both ends corresponding to the spring 100 wire. After the connection and spring 100 position adjustment are completed, the bolt connecting piece 7 can be used to rotate the spring 100. The locking member 51 on block 5 locks and fixes the connecting rod 4 at the corresponding position. Then, the driving member 2 drives the two sets of connecting seats 3 to slide in opposite directions, so that the two ends of the connecting seat 3 are stretched or pressed by the spring 100 connected by the connecting member 7 on the second connecting seat 6. At the same time, the force detection sensor set between the second connecting seat 6 and the slider 5 can detect the specific magnitude of the tension or pressure on the second connecting seat 6 in the corresponding state in real time. The operator can view and adjust the parameters in the corresponding state during the elastic strength test of the spring 100 by using the operation panel and control buttons in the control module set by the control structure commonly used in spring 100 testing machines.Compared to commonly available spring 100 testing machines, this spring 100 elastic strength testing fixture features a driving mechanism where the driving component 2 on the fixed base 1 drives the connecting base 3 to slide in opposite directions. Combined with the structural design of the slider 5 on the connecting rod 4, its second connecting base 6, and the connecting piece 7, and their connection method with the connecting base 3, this fixture can adapt to the clamping and fixing of springs 100 of different specifications and perform corresponding testing processes without affecting the normal testing process. This further improves the ease of operation, flexibility, and applicability of this spring 100 elastic strength testing fixture. Furthermore, by combining the connection method between the connecting piece 7 on the second connecting base 6 and the corresponding spring 100 wires at both ends, and the connection method between the force detection module 8 and the slider 5, it can ensure the connection and testing stability with the spring 100 while simultaneously controlling the two sets of sliders 5 at both ends of the spring 100. The two sets of force detection modules 8 perform a synchronous detection process of the magnitude of the force at corresponding positions, which can further improve the overall detection effect and accuracy of the spring 100. The stability of the spring 100 during the detection process can be judged by the parameter changes of the force detection modules 8 at corresponding positions at both ends of the spring 100. When the parameters detected by the force detection modules 8 are uniform and change at the same amplitude, the best test effect of the spring 100 can be achieved. When the parameter fluctuation amplitude of the force detection modules 8 at corresponding positions at both ends of the spring 100 is large, it indicates that there is an abnormality in the spring 100 or the connection point with the connecting part 7. This allows the operator to check and adjust the abnormality in a timely manner, reduce the degree of further damage to the spring 100, and further improve the detection effect and detection stability of this tooling for testing the elastic strength of the spring 100, meeting different usage requirements.

[0025] The size of the seat of the second connecting base 6 is adapted to the side size of the slider 5 corresponding to the connecting side. Furthermore, multiple sets of the force detection modules 8 acting between the slider 5 and the second connecting base 6 are arranged at intervals along the peripheral edge of the second connecting base 6. (See details...) Figure 3 As shown, the second connecting seat 6, which is designed to be adapted to the side size of the side connected to the slider 5, can combine with the force detection modules 8 arranged in multiple groups at intervals on the peripheral edge between the slider 5 and the second connecting seat 6. This can further improve the detection effect and stability of the two ends of the spring 100, improve the accuracy and stability of the data detection of the corresponding force magnitude, and improve the uniformity of the force distribution in the corresponding position of the second connecting seat 6. It can also further improve the abnormal detection effect when abnormal situations occur.

[0026] A cavity is formed between the multiple force detection modules 8 and the corresponding sides of the slider 5. A protruding plate 52 is also provided on the corresponding side of the slider 5 inside the cavity, and a through hole 521 is opened on the protruding plate 52. The addition of the structure of the protruding plate 52 inside the cavity can limit the position of the second connecting seat 6 without affecting the normal detection process of the force detection module 8. Thus, when the force detection sensor malfunctions in a certain state, the force detection module 8 is effectively reduced due to the resistance of the protruding plate 52 against the second connecting seat 6, thereby improving the stability of the force detection module 8. Furthermore, the opening of the through hole 521 on the protruding plate 52 can facilitate the wiring connection and organization of the multiple force detection modules 8, meeting different usage requirements.

[0027] The connector 7 includes a pin plate 71 and multiple sets of protrusions 72 on its wall surface. Multiple sets of pin grooves 73 are formed between the protrusions 72 and the pin plate 71, and multiple sets of evenly arranged slots 731 are formed within the pin grooves 73 on both sides of the protrusions 72. During connection, the connector 7 can be hooked together by the multiple sets of pin grooves 73 formed by the pin plate 71 extending along the corresponding wall surface of the second connecting seat 6 and the corresponding ends of the spring 100, which are surrounded by multiple coils of spring wire 100. Meanwhile, during the testing of spring 100, when it is stretched or pressed in the corresponding state, it can be clamped by multiple sets of slots 731 evenly arranged inside the corresponding pin groove 73. The connector 7 with this structure is convenient for clamping and fixing. At the same time, the horizontal and vertical arrangement of the connector 7 on the second connecting seat 6 can provide a certain degree of flexibility and applicability for springs 100 of different specifications and different types of compression springs or tension springs, and improve the clamping effect and connection stability of the two ends of spring 100.

[0028] A second connecting rod 9 is also provided below the fixed base 1, located on both sides of the driving component 2. Two sets of second sliders 91 are slidably mounted on the second connecting rod 9, respectively connected to two sets of connecting seats 3 above the fixed base 1. Specifically... Figure 2 As can be seen, the addition of the second connecting rod 9 to the structure allows the two sets of second sliders 91 connected to the connecting seat 3 through the second through slots 12 on the corresponding positions on both sides of the fixed seat 1 to slide synchronously along the corresponding rod of the second connecting rod 9 when the drive motor 22 drives the lead screw shaft 21 to rotate in the drive component 2, causing the main slider 23 on it to slide. This further improves the connection effect of the connecting seat 3 and the stability during the sliding process, effectively improving the driving stability of the drive component 2.

[0029] Both the connecting rod 4 and the second connecting rod 9 are marked with scale lines 491 of appropriate length. The marking of scale lines 491 on the connecting rod 4 can further improve the operation speed during the adjustment of the position of the two sets of sliders 5. The marking of scale lines 491 on the second connecting rod 9 can facilitate the observation and adjustment of the distance between the two sets of second sliders 91 and the two sets of connecting seats 3 connected to them. At the same time, it is convenient to view the data and adjust the status of the spring 100 when it is stretched or compressed during the test, which further improves the testing effect and the flexibility of use of this tooling for testing the elastic strength of the spring 100.

[0030] See Figure 4 The connecting rod 4 and the second connecting rod 9 are detachably mounted on the connecting seat 3 and the fixed seat 1 respectively through multiple sets of second locking parts 492 rotatably set at both ends. The connecting seat 3 and the second connecting seat 6 are detachably mounted on the fixed seat 1 and the slider 5 respectively. Specifically, the second locking part 492 adopts a bolt connection 7 structure and is detachably connected during rotation through a matching threaded connection structure at both ends of the connecting rod 4 and the second connecting rod 9. This facilitates the installation, disassembly, and replacement of the connecting rod 4 and the second connecting rod 9 respectively set on the connecting seat 3 and the fixed seat 1, as well as the slider 5 and the second slider 91 that slide on the rod respectively. At the same time, the matching structure of the connecting seat 3 is detachably mounted on the main slider 23 and the second slider 91 through the bolt connection 7. Furthermore, the second connecting seat 6 and the force detection module 8 are detachably mounted on the slider 5 through the bolt connection 7 structure, further improving the detachability and disassembly flexibility of the overall structure of this spring 100 elastic strength testing fixture, facilitating daily inspection and subsequent maintenance.

[0031] A support base is also installed on the fixed base 1 placed between the two sets of connecting seats 3. The top of the support base is curved, such as... Figure 1 The support base and the arc-shaped structure on its top, as shown, facilitate the quick placement of the spring 100 on the fixed base 1 in the early stage of testing, and facilitate the subsequent locking process of the connecting piece 7. At the same time, it can play a certain positional limitation role for the spring 100 during the testing process, thereby improving the stability of the spring 100 during the testing process.

[0032] The bottom of the fixed base 1 is also provided with multiple sets of support legs 13, and rubber pads 131 are attached to the bottom of the support legs 13. The addition of the support legs 13 and the bottom rubber pads 131 can facilitate the use of this tooling for testing the elastic strength of the spring 100 for supporting the position and further improve the positional stability.

[0033] The bottom edge of the fixing base 1 is also provided with multiple sets of second protruding plates 14 arranged at intervals. Each of the second protruding plates 14 is provided with a second through hole 141. For details, please refer to [link to relevant documentation]. Figure 2 As shown, the addition of multiple sets of second protruding plates 14 at the bottom of the fixed base 1 allows for the hanging of this spring 100 elastic strength testing fixture on a wall or other surface through the second through holes 141 on the second protruding plates 14, according to different usage requirements. This process does not affect the normal operation of the spring 100 elastic strength testing process and can meet different usage environments, further improving the flexibility of use.
