[0037] During the production of ornaments, fatigue tests need to be performed 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.

[0038] Based on the above considerations, in order to solve the problems of high labor cost and low efficiency caused by manual testing of a large variety of ornaments, a fatigue testing machine is designed. The controller of the mainframe structure can be used to control the driving structure to drive the second mounting seat to reciprocate towards the first mounting seat, so that the first clamping block of the first clamping component and the second clamping block of the second clamping component can clamp the same or different materials for fatigue testing, replacing the manual testing method, which can effectively improve the testing efficiency and accuracy.

[0039] Among them, the fatigue testing machine of the present application can be used for fatigue tests of precious metal ornaments (such as bracelets, bracelets, pendants, spring clasps, rings, earrings, etc.) or other metal products.

[0040] Next, the fatigue testing machine of the present application will be described in detail.

[0041] Please refer to Figures 1 to 5 , an embodiment of the present application provides a fatigue testing machine 1000, including a mainframe structure 100, a first clamping component 200, a second clamping component 300, and a driving structure 400; a controller (not shown in the figure) is provided inside the mainframe structure 100.

[0042] A test platform 110 is provided on the mainframe structure 100; the first clamping component 200 includes a first mounting seat 210 and at least two first clamping blocks 220 slidably arranged on the first mounting seat 210 along the first direction X, and the at least two first clamping blocks 220 are configured to be able to move towards each other to achieve clamping; the first mounting seat 210 is arranged on the test platform 110.

[0043] The second clamping component 300 includes a second mounting seat 310 and at least two second clamping blocks 320 slidably arranged on the second mounting seat 310 along the second direction Y, and the at least two second clamping blocks 320 are configured to be able to move towards each other to achieve clamping; the second mounting seat 310 is movably arranged on the test platform 110 along the third direction Z.

[0044] The driving structure 400 is electrically connected to the controller, the driving structure 400 is drivingly connected to the second mounting seat 310, and the driving structure 400 is configured to be able to drive the second mounting seat 310 to move along the third direction Z and towards the first mounting seat 210.

[0045] Among them, the first clamping component 200 includes a first mounting seat 210 and two slidable first clamping blocks 220. Optionally, the first clamping block 220 can be slidably connected to the first mounting seat 210 through a guide rail.

[0046] The first clamping block 220 can adjust the moving distance in the first direction X through a threaded knob; alternatively, the first clamping block 220 can also adjust the moving distance in the first direction X through a driving member such as a cylinder or a hydraulic cylinder. The clamping or loosening action is achieved by the movement of the two first clamping blocks 220 in the first direction X.

[0047] The first mounting seat 210 can be directly mounted on the test platform 110, 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.

[0048] The second fixture assembly 300 includes a second mounting seat 310 and two second clamping blocks 320. Optionally, the second clamping blocks 320 can be slidably connected to the second mounting seat 310 through guide rails.

[0049] The second clamping block 320 can adjust the moving distance in the second direction Y through a threaded knob; alternatively, the second clamping block 320 can also adjust the moving distance in the second direction Y through a driving member such as a cylinder or a hydraulic cylinder. The clamping or loosening action is achieved by the movement of the two second clamping blocks 320 in the second direction Y.

[0050] The second mounting seat 310 is movably arranged on the test platform 110 along the third direction Z; optionally, the second mounting seat 310 can be slidably mounted on the test platform 110 through guide rails.

[0051] The driving structure 400 is drivingly connected to the second mounting seat 310; wherein, the driving structure 400 includes but is not limited to a driving cylinder, a driving hydraulic cylinder, a driving motor, a driving turntable, etc. The driving structure 400 is drivingly connected to the second mounting seat 310 and can drive the second mounting seat 310 to reciprocate along the third direction Z and towards the first mounting seat 210.

[0052] Optionally, the two first clamping blocks 220 and the two second clamping blocks 320 can respectively clamp different parts of the same material to be tested; thus, during the process of the driving structure 400 driving the second mounting seat 310 to reciprocate along the third direction Z, the first clamping block 220 and the second clamping block 320 can clamp the same material to be tested for repeated pulling tests; exemplarily, it can be used for fatigue tests on springs, etc.

[0053] Or, the two first clamping blocks 220 and the two second clamping blocks 320 can clamp two different materials to be tested; thus, during the process of the driving structure 400 driving the second mounting seat 310 to reciprocate along the third direction Z, the material to be tested clamped by the first clamping block 220 and the material to be tested clamped by the second clamping block 320 can be subjected to collision tests; exemplarily, it can be used for impact, insertion and extraction tests on components such as impact pins, push rods or push blocks.

[0054] 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. Optionally, the first direction X and the second direction Y can be parallel to each other.

[0055] The above-mentioned third direction Z 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. It should be understood that the third direction Z should intersect the first direction X and the second direction Y, and the third direction Z is not parallel to the first direction X and the second direction Y, so as to avoid the moving direction of the driving structure 400 driving the second mounting seat 310 and the second clamping block 320 being parallel to the direction in which the second clamping block 320 clamps the material to be tested and affecting the test.

[0056] Exemplarily, in some embodiments, the first direction X and the second direction Y are parallel to each other, and the third direction Z is perpendicular to the first direction X and the second direction Y; for example, when the test platform 110 is a rectangular plane, both the first direction X and the second direction Y are parallel to the width direction of the test platform 110, and the third direction Z is parallel to the length direction of the test platform 110.

[0057] The 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.

[0058] A controller is provided inside the main machine structure 100. Thus, the driving structure 400 can be controlled through 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.

[0059] The fatigue testing machine 1000 provided by the embodiment of the present application can use the controller of the main machine structure 100 to control the driving structure 400 to drive the second mounting seat 310 to reciprocate towards the first mounting seat 210, so that the first clamping block 220 of the first fixture assembly 200 and the second clamping block 320 of the second fixture assembly 300 can clamp the same or different materials for fatigue testing, so as to replace the manual method for testing, which can effectively improve the test efficiency and the accuracy of the test.

[0060] Optionally, a display screen may also be provided on the host structure 100 for displaying the real-time speed at which the driving structure 400 drives the second mounting seat 310 to move, and may also display the number of fatigue tests (i.e., the number of times the driving structure 400 drives the second mounting seat 310 to reciprocate), etc. Button structures such as an emergency stop button, a speed regulator for operating the controller to adjust the speed at which the driving structure 400 drives the second mounting seat 310 to move, and a power on / off button may also be provided on the host structure 100.

[0061] Please refer to Figures 1 to 5 , in some embodiments, the first direction X is parallel to the test platform 110; and / or, the second direction Y is parallel to the test platform 110.

[0062] Among them, the first direction X may be set to be parallel to the test platform 110; exemplarily, the first direction X may be parallel to the length direction of the test platform 110; or, the first direction X may be parallel to the width direction of the test platform 110.

[0063] The second direction Y may be set to be parallel to the test platform 110; exemplarily, the second direction Y may be parallel to the length direction of the test platform 110; or, the second direction Y may be parallel to the width direction of the test platform 110.

[0064] In some embodiments, the first direction X and the second direction Y may be set to be parallel to each other. Exemplarily, both the first direction X and the second direction Y may be set to be parallel to the width direction of the test platform 110.

[0065] With such a setting, by setting the first direction X and / or the second direction Y to be parallel to the test platform 110, when using the first clamping block 220 and the second clamping block 320 to clamp the material to be tested, the clamping operation can be performed in a direction parallel to the test platform 110, and the operation is relatively convenient.

[0066] Please refer to Figures 1 to 5 , in some embodiments, the first direction X is parallel to the second direction Y.

[0067] In this embodiment, the first direction X is parallel to the second direction Y; thus, the direction in which the first clamping block 220 clamps the material to be tested is parallel to the direction in which the second clamping block 320 clamps the material to be tested.

[0068] With such a setting, during the clamping operation of the material to be tested, since the first direction X is parallel to the second direction Y, that is, the direction in which the first clamping block 220 clamps the material to be tested is parallel to the direction in which the second clamping block 320 clamps the material to be tested; it is more convenient for the first clamping block 220 and the second clamping block 320 to clamp the material to be tested and adjust the position of the material to be tested in the first direction X or the second direction Y, and the first clamping block 220 and the second clamping block 320 can be aligned more conveniently.

[0069] Please refer to Figures 1 to 5 , in some embodiments, the third direction Z is parallel to the test platform 110, and the third direction Z is perpendicular to the second direction Y.

[0070] Among them, the third direction Z is parallel to the test platform 110. Thus, the second mounting seat 310 can reciprocate on the test platform 110 and parallel to the test platform 110.

[0071] The third direction Z is perpendicular to the second direction Y; thus, the moving direction of the second mounting seat 310 driving the second clamping block 320 is perpendicular to the direction in which the second clamping block 320 clamps the material to be tested, and the probability of the second clamping block 320 interfering with the pulling or collision test of the material along the third direction Z is lower.

[0072] With such a setting, the driving structure 400 can drive the second mounting seat 310 to move along the third direction Z, and the second clamping block 320 can synchronously move along the third direction Z and reciprocate towards the first clamping block 220, so as to ensure the smoothness of the fatigue test process.

[0073] Please refer to Figures 1 to 5 , in some embodiments, the driving structure 400 includes a driving turntable 410 and a connecting rod 420. The driving turntable 410 is arranged along the third direction Z on the side of the second mounting seat 310 facing away from the first mounting seat 210, and a connecting member 411 is eccentrically arranged on the driving turntable 410; 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.

[0074] It can be understood that the driving turntable 410 can be rotated under the control of the controller to drive the second mounting seat 310 to move. The driving turntable 410 is installed on the test platform 110 and can rotate freely.

[0075] A connecting member 411 is eccentrically arranged on the driving turntable 410. The connecting member 411 can be, but is not limited to, structures such as a connecting block, a connecting rod, and a connecting plate.

[0076] 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.

[0077] Optionally, in some embodiments, the centers of the first mounting seat 210, the second mounting seat 310, and the driving turntable 410 may be located on the same straight line.

[0078] Please refer to Figures 1 to 5 , in some embodiments, a first adjusting mechanism 412 is further provided on the driving turntable 410. The first adjusting mechanism 412 is drivingly connected to the connecting member 411, and the first adjusting mechanism 412 is configured to be able to drive the connecting member 411 to move in the radial direction of the driving turntable 410.

[0079] With such a setting, the first adjusting mechanism 412 can drive the connecting member 411 to move in the radial direction of the driving turntable 410. Thus, when the length of the connecting rod 420 is fixed, the moving range of the second mounting seat 310 can be controlled, so that the test range can be adjusted.

[0080] In some embodiments, optionally, the first adjusting mechanism 412 may be, but is not limited to, an adjusting screw, an adjusting slider, etc.

[0081] Please refer to Figures 1 to 5 , in some embodiments, the first adjusting mechanism 412 includes a first threaded rod 413. The axial direction of the first threaded rod 413 is arranged along the radial direction of the driving turntable 410, and the first threaded rod 413 is configured to be able to freely rotate around its axial direction; a first threaded hole (not shown in the figure) is provided on the connecting member 411, and the connecting member 411 is screwed to the first threaded rod 413 through the first threaded hole.

[0082] It can be understood that during the rotation of the first threaded rod 413 around its axis, the connecting member 411 rotates relative to the first threaded rod 413 through the first threaded hole; thus, the connecting member 411 can move along the axial direction of the first threaded rod 413 to achieve position adjustment, that is, the connecting member 411 can adjust its position in the radial direction of the driving turntable 410.

[0083] Optionally, a receiving groove may be provided on the driving turntable 410 in the radial direction. The first threaded rod 413 is received in the receiving groove, and the connecting member 411 is screwed to the first threaded rod 413, and a part of the connecting member 411 extends out of the receiving groove to realize the rotational connection of the connecting rod 420.

[0084] Please refer to Figures 3 to 8 , in some embodiments, a first jaw 330 is provided on the second mounting seat 310; the fatigue testing machine 1000 further includes a third fixture assembly 500. The third fixture assembly 500 includes a third mounting block 510 and a second jaw 520 provided on the third mounting block 510; the third mounting block 510 is provided on the test platform 110 and is located on one side of the second mounting seat 310 in the second direction Y.

[0085] Among them, the first jaw 330 is used to pick up the material to be tested. It should be understood that the first jaw 330 includes two parts, namely the first jaw part 330 and the second jaw part 520, and the first jaw part 330 and the second jaw part 520 are used to perform the picking or releasing operation.

[0086] Optionally, the first jaw 330 can pick up by means of a threaded knob, or the first jaw 330 can pick up by means of driving parts such as a cylinder or a hydraulic cylinder.

[0087] The first jaw 330 can be fixedly connected to the second mounting seat 310 by a fastener; or the first jaw 330 can be rotatably connected to the second mounting seat 310, for example, rotatably connected to the second mounting seat 310 by a rotating shaft. Thus, the first jaw 330 can lock the grasping angle or choose not to lock it during the process of grasping the material to be tested to meet the test requirements.

[0088] The second jaw 520 is used to pick up the material to be tested. It should be understood that the second jaw 520 includes two parts, namely the third jaw part and the fourth jaw part, and the third jaw part and the fourth jaw part are used to perform the picking or releasing operation.

[0089] Optionally, the second jaw 520 can pick up by means of a threaded knob, or the second jaw 520 can pick up by means of driving parts such as a cylinder or a hydraulic cylinder.

[0090] The second jaw 520 can be fixedly connected to the third mounting block 510 by a fastener; or the second jaw 520 can be rotatably connected to the third mounting block 510, for example, rotatably connected to the third mounting block 510 by a rotating shaft. Thus, the second jaw 520 can lock the grasping angle or choose not to lock it during the process of grasping the material to be tested to meet the test requirements.

[0091] The third mounting block 510 is arranged on the test platform 110 and on one side of the second mounting seat 310 in the second direction Y; the first jaw 330 and the second jaw 520 can pick up different parts of the same material to be tested, and the first jaw 330 is driven by the second mounting seat 310 to move along the third direction Z to realize the repeated pulling of the material to be tested, so as to realize the fatigue test of the material to be tested.

[0092] With such a setting, by driving the driving structure 400 to drive the second mounting seat 310 to move, the fatigue test between the first clamping block 220 and the second clamping block 320 can be realized at the same time, and the fatigue use between the first jaw 330 and the second jaw 520 can be realized, so as to effectively improve the application range of the fatigue testing machine 1000.

The slide plate can be installed on the test platform 110 through fasteners; a slider is slidably connected to the guide rails of the slide plate, and the slider can be fixedly connected to the second mounting seat 310 through fasteners. Thus, the second mounting seat 310 can be slidably connected to the guide rails through the slider, so that the second mounting seat 310 can move relative to the test platform 110 along the third direction Z.
