For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0042] During the production of ornaments, it is necessary to conduct fatigue tests on the ornaments. However, since there are many types of ornaments, including but not limited to bracelets, bracelets, pendants, spring clasps, rings, earrings, etc.; in the related art, there is no special equipment for testing various types of ornaments, and only manual testing methods can be used to test different ornaments, resulting in high labor costs and low efficiency.

[0043] Based on the above considerations, in order to solve the problem of high labor costs and low efficiency caused by manual testing of a large number of types of ornaments, a fatigue testing machine is designed. The controller of the main machine structure is used to control the driving structure to drive the second mounting seat to reciprocate in the first direction, so that the first jaw of the first fixture assembly and the second jaw of the second fixture assembly can clamp the same or different materials for fatigue testing, replacing the manual testing method, and effectively improving the testing efficiency and accuracy.

[0044] Next, the fatigue testing machine of the present application will be described in detail.

[0045] Please refer to Figures 1 to 7, an embodiment of the present application provides a fatigue testing machine 1000, including a main machine structure 100, a first fixture assembly 200, a second fixture assembly 300, and a driving structure 400; a controller (not shown in the figure) is provided inside the main machine structure 100, and a test platform 110 is provided on the main machine structure 100.

[0046] Among them, a test platform 110 is provided on the main machine structure 100, and the test platform 110 is used to provide an installation and support environment for the first mounting seat 210, the second mounting seat 310, the driving structure 400, etc.

[0047] A controller is provided inside the main machine structure 100. Thus, the driving structure 400 can be controlled by the controller, so that the driving structure 400 can drive the second mounting seat 310 to reciprocate at a certain speed and frequency according to preset requirements (such as speed, frequency, etc.). It can be understood that the controller can be a common controller such as a single-chip microcomputer or a PLC.

[0048] The first fixture assembly 200 includes a first mounting seat 210 and a first jaw 220 rotatably provided on the first mounting seat 210; the first mounting seat 210 is provided on the test platform 110.

[0049] The first mounting seat 210 can be directly mounted on the test platform 110 by means of fastener connection, welding, clamping, etc.; or, the first mounting seat 210 can be mounted on the test platform 110 through an adjusting device (such as a linear cylinder, a guide rail, etc.) to achieve position adjustment.

[0050] Optionally, the first mounting seat 210 includes, but is not limited to, structures such as a mounting plate, a mounting block, a mounting bracket, etc.

[0051] The first jaw 220 is used to clamp the material to be tested; optionally, the first jaw 220 can achieve the clamping action in the form of being driven by a driving member, such as a manipulator, etc.; or, the first jaw 220 can also achieve the clamping by means of a screw-driven slide table. The number of the first jaws 220 can be one or any number more than one.

[0052] The first jaw 220 is rotatably provided on the first mounting seat 210; optionally, the first jaw 220 can be hinged or rotatably connected to the first mounting seat 210. Exemplarily, a first rotating shaft 224 is provided on the first jaw 220, a first rotating hole 211 can be opened on the first mounting seat 210, and the first rotating shaft 224 can be rotatably inserted into the first rotating hole 211 so that the first jaw 220 can rotate relative to the first mounting seat 210; specifically as Figure 5 shown.

[0053] In some embodiments, a first locking structure 212 may be further provided. The first locking structure 212 is used to lock the first jaw 220 so that the first jaw 220 can be locked relative to the first mounting seat 210. Exemplarily, the first locking structure 212 may be a locking pin. The locking pin may be screwed onto the first mounting seat 210 and inserted into the first rotation hole 211. By rotating the locking pin, the depth of the locking pin inserted into the first rotation hole 211 can be adjusted, so that the locking pin can move to connect with the first rotating shaft 224 in a way of abutting, inserting or screwing to achieve the locking of the rotation action, or the first rotating shaft 224 can be released by rotating the locking pin so that the first jaw 220 can freely rotate through the first rotating shaft 224.

[0054] In this way, the first jaw 220 can be locked or freely rotated according to the test requirements of the material to be tested, so that during the test, the angle can be locked when the first jaw 220 grabs the material to be tested, or the angle can be selected not to be locked.

[0055] The second fixture assembly 300 includes a second mounting seat 310 and a second jaw 320 provided on the second mounting seat 310. The second mounting seat 310 is movably arranged on the test platform 110 along the first direction X, and the second mounting seat 310 is located on one side of the first mounting seat 210 in the second direction Y. Among them, the first direction X and the second direction Y intersect.

[0056] The second mounting seat 310 can be directly mounted on the test platform 110 by means of fastener connection, welding, clamping, etc.; or the second mounting seat 310 can be mounted on the test platform 110 through an adjusting device (such as a linear cylinder, a guide rail, etc.) to achieve position adjustment.

[0057] Optionally, the second mounting seat 310 includes, but is not limited to, structures such as a mounting plate, a mounting block, a mounting bracket, etc.

[0058] The second jaw 320 is used to grab the material to be tested. Optionally, the second jaw 320 can achieve the grabbing action in the form of being driven by a driving member, such as a manipulator, etc.; or the second jaw 320 can also achieve the grabbing by means of a screw-driven slide. The number of the second jaws 320 can be one or any number more than one.

[0059] The second jaw 320 is rotatably arranged on the second mounting seat 310. Optionally, the second jaw 320 can be hinged or rotatably connected to the second mounting seat 310. Exemplarily, a second rotating shaft 324 is provided on the second jaw 320, a second rotation hole 311 can be opened on the second mounting seat 310, and the second rotating shaft 324 can be rotatably inserted into the second rotation hole 311 so that the second jaw 320 can rotate relative to the second mounting seat 310. Specifically, as Figure 8 shown.

[0060] In some embodiments, a second locking structure 312 may be further provided. The second locking structure 312 is used to lock the second jaw 320 so that the second jaw 320 can be locked relative to the second mounting seat 310. Exemplarily, the second locking structure 312 may be a locking pin. The locking pin may be screwed onto the second mounting seat 310 and inserted into the second rotation hole 311. By rotating the locking pin, the depth of the locking pin inserted into the second rotation hole 311 can be adjusted, so that the locking pin can move to connect with the second rotating shaft 324 in a way of abutting, plugging or screwing to lock the rotation movement. Or by rotating the locking pin, the second rotating shaft 324 can be loosened so that the second jaw 320 can rotate freely through the second rotating shaft 324.

[0061] In this way, the second jaw 320 can be locked or rotated freely according to the test requirements of the material to be tested, so that during the test, the angle of the second jaw 320 can be locked when clamping the material to be tested, or the angle can be not locked.

[0062] Exemplarily, in some embodiments, the first jaw 220 can be locked to the first rotating shaft 224 through the first locking structure 212 to achieve locking, and the first jaw 220 cannot rotate relative to the first mounting seat 210. At the same time, the second jaw 320 can be locked to the second rotating shaft 324 through the second locking structure 312 to achieve locking, and the second jaw 320 cannot rotate relative to the second mounting seat 310. Thus, when the driving structure 400 drives the second mounting seat 310 to reciprocate along the first direction X so that the first jaw 220 and the second jaw 320 respectively clamp different parts of the same material to be tested for a tensile test, the angles of the first jaw 220 and the second jaw 320 are locked dead.

[0063] Or, in some other embodiments, one of the first jaw 220 and the second jaw 320 can rotate and the other is locked. For example, the first jaw 220 is locked relative to the first mounting seat 210 and cannot rotate, while the second jaw 320 can rotate freely relative to the second mounting seat 310 and through the second rotating shaft 324. Or, the second jaw 320 is locked relative to the second mounting seat 310 and cannot rotate, while the first jaw 220 can rotate freely relative to the first mounting seat 210 and through the first rotating shaft 224. When the driving structure 400 drives the second mounting seat 310 to reciprocate along the first direction X so that the first jaw 220 and the second jaw 320 respectively clamp different parts of the same material to be tested for a tensile test, the angle of one of the first jaw 220 and the second jaw 320 is locked dead, and the other can clamp the material to be tested and rotate.

[0064] Alternatively, in other embodiments, the first locking structure 212 can be rotationally adjusted to release the locking of the first rotating shaft 224, so that the first clamping jaw 220 can freely rotate through the first rotating shaft 224; at the same time, the second locking structure 312 is rotationally adjusted to release the locking of the second rotating shaft 324, so that the second clamping jaw 320 can freely rotate through the second rotating shaft 324; when the driving structure 400 drives the second mounting base 310 to reciprocate along the first direction X to make the first clamping jaw 220 and the second clamping jaw 320 respectively clamp different parts of the same material to be tested for a pulling test, when the first clamping jaw 220 and the second clamping jaw 320 respectively clamp different parts of the same material to be tested for a pulling test, the first clamping jaw 220 and the second clamping jaw 320 can still freely rotate.

[0065] Among them, the above-mentioned first direction X can be any direction, for example, it can be any direction parallel to the test platform 110, or a direction intersecting or perpendicular to the test platform 110, etc. The above-mentioned second direction Y can be any direction, for example, it can be any direction parallel to the test platform 110, or a direction intersecting or perpendicular to the test platform 110, etc. The first direction X intersects with the second direction Y. Optionally, the first direction X can be perpendicular to the second direction Y.

[0066] Exemplarily, in some embodiments, when the test platform 110 is a rectangular plane, the first direction X is parallel to the length direction of the test platform 110, and the second direction Y is parallel to the width direction of the test platform 110.

[0067] The driving structure 400 is electrically connected to the controller; the driving structure 400 is drivingly connected to the second mounting base 310, and the driving structure 400 is configured to be able to drive the second mounting base 310 to move along the first direction X.

[0068] The driving structure 400 is drivingly connected to the second mounting base 310; among them, the driving structure 400 includes but is not limited to a driving cylinder, a driving hydraulic cylinder, a driving motor, a driving turntable, etc.

[0069] The driving structure 400 is drivingly connected to the second mounting base 310 and can drive the second mounting base 310 to reciprocate along the first direction X; thus, the distance between the first clamping jaw 220 and the second clamping jaw 320 will continuously change. In this way, when the first clamping jaw 220 and the second clamping jaw 320 clamp different parts of the same material to be tested, the material to be tested can be repeatedly pulled and tested.

[0070] The fatigue testing machine 1000 provided in the present application can use the controller of the main structure 100 to control the driving structure 400 to drive the second mounting seat 310 to move back and forth along the first direction X, so that the first clamping jaw 220 of the first clamping assembly 200 and the second clamping jaw 320 of the second clamping assembly 300 can clamp the same or different materials for fatigue testing, thereby replacing manual testing and effectively improving test efficiency and test accuracy.

[0071] Optionally, the host structure 100 may be provided with a display screen for displaying the real-time speed of the second mounting seat 310 driven by the drive structure 400, and the number of fatigue tests (i.e., the number of reciprocating movements of the second mounting seat 310 driven by the drive structure 400). The host structure 100 may also be provided with button structures such as an emergency stop button, a speed regulator for operating a controller to adjust the speed of the second mounting seat 310 driven by the drive structure 400, and a power button.

[0072] Please refer to Figures 1 to 7 In some embodiments, the first fixture assembly 200 further includes a first adjustment assembly 230 , which is configured to adjust the position of the first mounting base 210 along the second direction Y.

[0073] It can be understood that the first adjustment component 230 is capable of adjusting the position of the first mounting seat 210 along the second direction Y; thereby, the relative positions of the first mounting seat 210 and the second mounting seat 310 in the second direction Y will change, and the distance between the first clamping jaw 220 and the second clamping jaw 320 in the second direction Y will change synchronously.

[0074] In this way, the relative positions of the first clamping jaw 220 and the second clamping jaw 320 in the second direction Y can be adjusted by the first adjusting component 230 , so that it can be suitable for materials to be tested of different sizes, and can effectively improve the applicability of the fatigue testing machine 1000 .

[0075] Please refer to Figures 1 to 7 In some embodiments, the first adjustment assembly 230 includes a first adjustment seat 231 and a first adjustment screw 232; the first adjustment seat 231 is set on the test platform 110, and the first mounting seat 210 is slidably connected to the first adjustment seat 231 along the second direction Y; the first adjustment screw 232 is rotatably set on the first adjustment seat 231, and the axial direction of the first adjustment screw 232 is set toward the second direction Y; a first threaded hole (not shown in the figure) is opened on the first mounting seat 210, and the first adjustment screw 232 is screwed into the first threaded hole.

[0076] Among them, the first adjustment seat 231 includes, but is not limited to, structures such as adjustment blocks, adjustment plates, and adjustment brackets. The first adjustment seat 231 can be fixedly connected to the test platform 110 by means of fastener connection, welding, snap connection, etc.

[0077] The first mounting seat 210 is slidably connected to the first adjustment seat 231 in the second direction Y; optionally, the first mounting seat 210 can be slidably mounted on the first adjustment seat 231 through a rail structure.

[0078] The first adjustment screw 232 is rotatably arranged on the first adjustment seat 231. When the first adjustment screw 232 rotates around the axis, the first mounting seat 210 can rotate relative to the first adjustment screw 232 through the first threaded hole; thus, the first mounting seat 210 can move along the axial direction of the first adjustment screw 232 to achieve position adjustment, that is, the first mounting seat 210 can adjust its position in the second direction Y.

[0079] Exemplarily, in some embodiments, the first adjustment seat 231 may include a first seat body portion and first end blocks provided at opposite ends of the first seat body portion in the second direction Y. A slide rail is convexly provided on the first seat body portion, and the first mounting seat 210 is slidably connected to the slide rail; the first adjustment screw 232 is sequentially passed through and connected to the first end block at one end, the first mounting seat 210, and the first end block at the other end in the second direction Y; thus, by rotating the first adjustment screw 232, the positions of the first mounting seat 210 and the first jaw 220 in the second direction Y can be adjusted.

[0080] Please refer to Figures 1 to 7 , in some embodiments, the first fixture assembly 200 further includes a second adjustment assembly 240, and the second adjustment assembly 240 is configured to be able to adjust the position of the first mounting seat 210 in the first direction X.

[0081] It can be understood that the second adjustment assembly 240 can adjust the position of the first mounting seat 210 in the first direction X; thus, the relative position between the first mounting seat 210 and the second mounting seat 310 in the first direction X will change, and the distance between the first jaw 220 and the second jaw 320 in the first direction X will change synchronously.

[0082] In this way, the relative position between the first jaw 220 and the second jaw 320 in the first direction X can be adjusted through the second adjustment assembly 240, so that it can be applicable to test materials of different sizes and can effectively improve the applicability of the fatigue testing machine 1000.

[0083] Please refer to Figures 1 to 7In some embodiments, the second adjustment assembly 240 includes a second adjustment seat 241 and a second adjustment screw 242; the second adjustment seat 241 is connected to the test platform 110, and the first adjustment seat 231 is slidably connected to the test platform 110 along the first direction X; the second adjustment screw 242 is rotatably set on the second adjustment seat 241, and the axial direction of the second adjustment screw 242 is set toward the first direction X; a second threaded hole (not shown in the figure) is opened on the first adjustment seat 231, and the second adjustment screw 242 is screwed into the second threaded hole.

[0084] The second adjustment seat 241 includes but is not limited to an adjustment block, an adjustment plate, an adjustment bracket, etc. The first adjustment seat 231 can be fixedly connected to the test platform 110 by fastener connection, welding, clamping, etc.

[0085] The first adjustment seat 231 is slidably disposed on the test platform 110 along the first direction X; optionally, the first adjustment seat 231 may be slidably disposed on the test platform 110 via a guide rail structure.

[0086] The second adjusting screw 242 is rotatably arranged on the second adjusting seat 241. When the second adjusting screw 242 rotates around the axis, the first adjusting seat 231 can rotate relative to the second adjusting screw 242 through the second threaded hole; thus, the first adjusting seat 231 can move along the axial direction of the second adjusting screw 242 to achieve position adjustment, that is, the first adjusting seat 231 can adjust its position along the first direction X.

[0102] One end of the connecting rod 420 is rotatably connected to the connecting member 411, and the opposite end of the connecting rod 420 is rotatably connected to the second mounting seat 310; thus, when the driving turntable 410 rotates, the connecting rod 420 can be driven to move, and the connecting rod 420 can repeatedly push and pull the second mounting seat 310 according to the change of the position of the connecting member 411, thereby realizing the reciprocating movement of the second mounting seat 310. Optionally, a convex structure (such as a connecting column, etc.) can be arranged on the second mounting seat 310 to facilitate the rotational connection and assembly of the connecting rod 420.

[0103] Optionally, in some embodiments, the centers of the second mounting seat 310 and the driving turntable 410 can be located on the same straight line parallel to the first direction X.

[0108] It can be understood that during the rotation of the first threaded rod 431 about its axis, the connecting member 411 rotates relative to the first threaded rod 431 through the first threaded hole; thus, the connecting member 411 can move along the axial direction of the first threaded rod 431 to adjust its position, that is, the connecting member 411 can adjust its position along the radial direction of the driving turntable 410.

[0109] Optionally, a receiving groove can be formed in the driving turntable 410 along the radial direction, the first threaded rod 431 is received in the receiving groove, the connecting member 411 is screwed onto the first threaded rod 431, and a part of the connecting member of 411 extends out of the receiving groove to rotatably connect the connecting rod 420.

[0112] Wherein, the sliding direction of the first clamping blocks 330 can be any direction, for example, parallel to the second direction Y or perpendicular to the testing platform 110, etc.

[0113] The first clamping driving members 340 are used to drive the first clamping blocks 330 so that the two first clamping blocks 330 move towards or away from each other, thereby achieving the purpose of clamping or releasing the material to be tested.

[0114] Among them, the first clamping drive member 340 can be but is not limited to a cylinder, a hydraulic cylinder, a threaded knob, etc.; for example, when the first clamping drive member 340 is a threaded knob, the threaded knob can be screwed to the first clamping block 330, so that the first clamping block 330 can be driven to move by rotating the threaded knob.

[0115] The fatigue testing machine 1000 also includes a third clamp assembly 500, which includes a third mounting seat 510, two second clamping blocks 520 and two second clamping driving members 530; the third mounting seat 510 is arranged on the test platform 110, and in the first direction X, the third mounting seat 510 is located on the side of the second mounting seat 310 away from the driving structure 400; the second clamping block 520 is slidably connected to the third mounting seat 510 along the second direction Y, and the second clamping driving member 530 is drivingly connected to the second clamping block 520.

[0117] In the first direction X, the third mounting seat 510 is located on the side of the second mounting seat 310 that is away from the driving structure 400; therefore, when the driving structure 400 drives the third mounting seat 510 to move back and forth along the first direction X, the distance between the first clamping block 330 on the second mounting seat 310 and the second clamping block 520 on the third mounting seat 510 will continuously change, thereby enabling a tensile test on the same material to be tested, or a collision test on different materials, etc.

[0118] The second clamping block 520 is slidably connected to the third mounting base 510 . The sliding direction of the second clamping block 520 can be any direction, such as parallel to the second direction Y or perpendicular to the direction of the test platform 110 .
