[0030] Embodiment one:

[0031] As shown in Figs. 1-3 The present application provides a kind of dynamic balance testing device 1, comprising: base 10, mounting seat 20, first clamping component 30, drive assembly and testing machine, mounting seat 20 movably set in the top surface of base 10, first clamping component 30 is configured as two, two first clamping component 30 respectively movably set in the side of mounting seat 20 away from base 10, first clamping component 30 is suitable for clamping circular shaft, drive assembly is connected with two first clamping component 30 respectively, drive assembly is suitable for driving two first clamping component 30 towards or away from each other moves, testing machine is set in the top surface of base 10, mounting seat 20 can be selectively moved towards or away from testing machine.

[0032] It is worth mentioning that first clamping component 30 is provided with first containing space for fixing circular shaft, the first containing space of two first clamping component 30 is used for fixing the two ends (the axial direction of circular shaft is parallel to the length direction of dynamic balance testing device 1) of circular shaft in axial direction respectively.Note that the above-mentioned fixed refers to the fixing of the outer peripheral wall of circular shaft, i.e. circular shaft can rotate in circumferential direction.Testing machine has rotatable output shaft, output shaft and one end of circular shaft are linked through synchronous belt, i.e. testing machine can make output shaft rotate when working, then synchronous belt can drive circular shaft to rotate, to realize the dynamic balance of testing circular shaft.

[0033] In some embodiments, the base 10 serves as the basic support structure of the entire dynamic balancing test device 1, the mounting base 20 is located above the base 10, and the mounting base 20 can be moved on the base 10 to allow adjustment of the position of the circular shaft to be tested relative to the testing machine, or adjustment of the axial position of the two first clamping assemblies 30 relative to the circular shaft.

[0034] The two first clamping assemblies 30 are installed on the side of the mounting seat 20 away from the base 10. The two first clamping assemblies 30 can be close to or away from each other to adapt to circular shafts of different sizes and fix them. The driving assembly is connected to the two first clamping assemblies 30. The driving assembly is responsible for controlling the relative movement of the two first clamping assemblies 30 so that the two first clamping assemblies 30 can move toward or away from each other at the same time, thereby achieving simultaneous adjustment of the axial positions of the two first clamping assemblies 30 relative to the circular shaft. The testing machine is placed on the base 10. The testing machine is used to perform specific dynamic balancing tests. The mounting seat 20 can be moved to a position closer to or away from the testing machine as needed.

[0035] It's understood that the core principle of the dynamic balancing tester 1 is to ensure a secure and even grip on the shaft by precisely controlling the distance between the two first clamping assemblies 30. During dynamic balancing testing, the shaft must be precisely positioned and secured to ensure accurate test results. The dual first clamping assemblies 30, coupled with a drive assembly that synchronously controls both, allow the operator to quickly and easily complete the shaft installation process without having to manually adjust each clamping point, significantly simplifying preparation.

[0036] In addition, the feature that the mounting base 20 can move on the base 10 allows the relative position between the circular shaft and the testing machine to be flexibly adjusted according to actual needs during the test process, such as for better observation, adjustment or analysis of specific parts, thereby increasing the flexibility of the dynamic balancing test.

[0037] According to the dynamic balancing test device 1 of the present invention, the position of the first clamping assembly 30 is automatically adjusted, which reduces the need for manual intervention, speeds up the clamping speed of the circular shaft, and improves the overall dynamic balancing test efficiency. Moreover, the synchronous control mechanism ensures that the force on both sides of the circular shaft is uniform, avoiding measurement errors caused by excessive tightness or looseness on one side. It can also avoid the need to adjust the two first clamping assemblies 30 separately, further speeding up the clamping speed of the circular shaft. Of course, the design of the movable mounting seat 20 provides more test configuration options, which helps to respond quickly to circular shafts of different specifications or specific test requirements. At the same time, the dynamic balancing test device 1 of the present application has low operating difficulty, and even non-professionals can quickly master the usage method, reducing training costs.

[0038] Example 2:

[0039] In this embodiment, based on the first embodiment, one of the first clamping components 30 is provided with a first threaded hole, and the other first clamping component 30 is provided with a second threaded hole. The driving component includes: a rotating rod 41, the rotating rod 41 is rotatably connected to the mounting seat 20, and the rotating rod 41 is provided with a first thread and a second thread spaced apart from each other in the axial direction. The first thread is suitable for cooperating with the first threaded hole, and the second thread is suitable for cooperating with the second threaded hole. The rotation direction of the first thread and the second thread is opposite.

[0040] It will be appreciated that the rotational motion of the rotating rod 41 is converted into linear motion of the first clamping assembly 30, and since the first and second threads have opposite rotation directions, when the rotating rod 41 rotates, the rotating rod 41 simultaneously moves the two first clamping assemblies 30 in opposite directions, thereby simultaneously adjusting the axial positions of the two first clamping assemblies 30 relative to the circular axis. For example, if the rotating rod 41 rotates clockwise, the two first clamping assemblies 30 will simultaneously move toward each other, or if the rotating rod 41 rotates counterclockwise, the two first clamping assemblies 30 will simultaneously move away from each other.

[0041] Therefore, the rotation of the rotating rod 41 can ensure that the two first clamping assemblies 30 can move toward or away from each other at the same speed at the same time, thereby adjusting the clamping position of the circular shaft so that the two first clamping assemblies 30 can be evenly located at both ends of the circular shaft in the axial direction, that is, the two clamping assemblies can achieve uniform distribution of the clamping force on the circular shaft. The evenly distributed clamping force helps to maintain the stability of the circular shaft during the test. Of course, it is only necessary to control the rotation of the rotating rod 41 to adjust the position of the two first clamping assemblies 30, without manually adjusting each first clamping assembly 30 individually, thereby improving the clamping efficiency of the circular shaft and thus improving the dynamic balancing test efficiency of the circular shaft.

[0042] Example 3:

[0043] In this embodiment, based on the second embodiment, the mounting base 20 is provided with two support columns 21 extending in the height direction, and the two support columns 21 are spaced apart from each other in the length direction. The rotating rod 41 is rotatably connected to the two support columns 21 respectively, and a limiting ring is provided between the first thread and the second thread of the rotating rod 41. The limiting ring is provided between the two support columns 21, and the two ends of the limiting ring in the axial direction are respectively stopped by the two support columns 21.

[0044] In some embodiments, the support column 21 provides the necessary mechanical support so that the rotating rod 41 can be stably rotated in the horizontal direction without being offset or bent due to the gravity of the rotating rod 41 itself or other external forces, by rotatingly connecting the rotating rod 41 with the two support columns 21 respectively, the two support columns 21 are spaced in the axial direction to support the rotating rod 41, which ensures that the rotation center line of the rotating rod 41 is consistent with the design requirements, which helps to maintain the accuracy of the entire drive assembly.

[0045] Since the limiting ring is in close contact with the two support columns 21 at both ends in the axial direction, the rotating rod 41 can be prevented from sliding in the axial direction during operation, that is, the limiting ring is suitable for limiting the movement of the rotating rod 41 in the axial direction, of course, the limiting ring also plays an auxiliary positioning role, ensuring that the threaded section on the rotating rod 41 is correctly aligned with the threaded hole on the corresponding clamping assembly, and moreover, the above-mentioned arrangement also helps to reduce the vibration generated when the rotating rod 41 rotates, improving the stability of the entire drive assembly.

[0046] According to some embodiments of the present application, the drive assembly further comprises: a driving member 42 and a transmission member 43, the driving member 42 is connected with the mounting seat 20, the driving member 42 is provided with a rotatable output end, one end of the transmission member 43 is connected with the output end, the other end of the transmission member 43 is connected with the limiting ring, and the transmission member 43 is suitable for linkage between the output end and the limiting ring.

[0047] In some embodiments, the driving member 42 is a power source connected with the mounting seat 20, the driving member 42 is provided with a rotatable output end, and the driving member 42 can be an electric motor, a pneumatic motor or other types of rotating power device. One end of the transmission member 43 is connected with the output end of the driving member 42, and the other end of the transmission member 43 is connected with the limiting ring on the rotating rod 41, and the transmission member 43 transmits the rotating motion generated by the driving member 42 to the rotating rod 41, thereby realizing the synchronous control of the two first clamping assemblies 30.

[0048] It can be understood that when the driving member 42 starts, the output end starts to rotate, at this time, the transmission member 43 plays a role of a bridge to transmit the rotating motion of the driving member 42 to the rotating rod 41, that is, the transmission member 43 can effectively transmit the rotating torque of the driving member 42 to the rotating rod 41, and the rotating rod 41 rotates to drive the two first clamping assemblies 30 to move relatively.

[0049] It is worth mentioning that in addition to limiting the position of the rotating rod 41 in the axial direction, the limiting ring also serves as a connection point of the transmission member 43, which ensures that the transmission member 43 can effectively transmit the driving force to the rotating rod 41.

[0050] Therefore, through the cooperation of the driving member 42 and the transmission member 43, the rotation angle and speed of the rotating rod 41 can be controlled very accurately, thereby achieving precise control of the circular shaft. Moreover, the setting of the driving component reduces the need for manual operation and improves the speed and efficiency of the test preparation stage.

[0051] According to some embodiments of the present invention, the outer peripheral wall of the limiting ring is provided with a first tooth portion, the outer peripheral wall of the output end is provided with a second tooth portion, and the transmission member 43 is constructed as a chain, one end of the chain is engaged with the first tooth portion, and the other end of the chain is engaged with the second tooth portion.

[0052] In some embodiments, a first tooth portion is provided on the outer periphery of the limiting ring, and the limiting ring and the first tooth portion are jointly constructed as a sprocket role, and a second tooth portion is provided on the outer peripheral wall of the output end, and the second tooth portion and the output end are also jointly constructed as a sprocket role. Thus, the two ends of the chain are respectively engaged with the first tooth portion and the second tooth portion, thereby realizing the linkage between the output end and the limiting ring, that is, when the driving member 42 is working, the output end can be rotated, and then the output end rotates to drive the chain to rotate, and the chain rotates to drive the limiting ring to rotate.

[0053] It is worth mentioning that the meshing method of the chain and the teeth ensures the high accuracy of the transmission process and reduces the errors caused by sliding or slipping. Moreover, the chain transmission system has a stable structure and can maintain good stability during long-term operation. Of course, the chain transmission system is easy to inspect and maintain, which reduces the maintenance cost of long-term use. At the same time, the high efficiency of the chain transmission system makes the operation of the entire dynamic balancing test device 1 smoother, thereby improving the dynamic balancing test efficiency of the circular shaft.

[0054] Example 4:

[0055] In this embodiment, based on the first embodiment, the mounting seat 20 is provided with a first slide groove 22 extending in the length direction, and a first slider is provided at the bottom of the first clamping assembly 30 , and the first slider is movably received in the first slide groove 22 .

[0056] In some embodiments, the inner peripheral wall of the first slide groove 22 can limit the outer peripheral wall of the first slider, so that the first slider can stably move along the extension direction of the first slide groove 22, and then the first clamping assembly 30 can stably move relative to the mounting seat 20 in the length direction.

[0057] In other embodiments, a second slide groove 11 extending in the length direction is provided at the top of the base 10, and a second slider is provided on the side of the mounting seat 20 facing the base 10. The second slider is movably provided in the second slide groove 11, and the inner peripheral wall of the second slide groove 11 is suitable for restricting the outer peripheral wall of the second slider, so that the second slider can move stably along the extension direction of the second slide groove 11, and then the mounting seat 20 can move stably relative to the base 10 in the length direction.

[0058] According to some embodiments of the present invention, the dynamic balancing test device 1 further includes: a locking member, one end of which is rotatably connected to the mounting base 20, and a locking block is provided at the other end of the locking member; wherein the base 10 is provided with a plurality of locking holes, and the plurality of locking holes are spaced apart from each other in the length direction, and the locking member is rotated to selectively allow the locking block to be accommodated in one of the locking holes.

[0059] In some embodiments, the locking member can be a rod, a plate or an object of other shapes. The main function of the locking member is to provide a quick and reliable mechanism to fix the position of the mounting base 20, that is, when the locking member rotates, the locking block can be inserted into a lock hole on the base 10, thereby preventing the mounting base 20 from continuing to move along the length direction of the base 10. The locking mechanism prevents the mounting base 20 from being displaced due to external force or vibration during the test process, thereby increasing the safety of the operation. The locking method is simple and effective, does not require an additional power source, and can be achieved only through manual operation.

[0060] It is worth noting that the multiple lock holes set on the base 10 provide a variety of possible fixing positions, so that the tester can flexibly select the optimal position of the mounting base 20 according to actual needs. The intervals between the lock holes are set according to specific application requirements to ensure sufficient adjustment range and accuracy.

[0061] According to some embodiments of the present invention, the dynamic balancing test device 1 further includes: a second clamping assembly 50, which is fixedly connected to the base 10, and is arranged between the testing machine and the mounting seat 20, and is suitable for clamping a circular shaft.

[0062] It can be understood that the second clamping assembly 50 provides another support point. The second clamping assembly 50 works in conjunction with at least one first clamping assembly 30 to enhance the stability of the circular shaft during the test. Through multiple clamping points, the position and posture of the circular shaft can be better controlled to reduce vibration or other unstable factors caused by insufficient single-point support.

[0063] It is worth mentioning that since the second clamping assembly 50 is fixedly connected to the base 10, the second clamping assembly 50 will not move like the mounting base 20, that is, the second clamping assembly 50 provides a stable reference point, which helps to ensure that the circular shaft maintains a consistent position throughout the test process, thereby improving the accuracy and repeatability of the test results.

[0064] In some embodiments, the top of the mounting base 20 is further provided with a moving base selectively movable in the length direction relative to the mounting base 20, and the support column 21 and the driving assembly are both arranged on the moving base, so that when the circular shaft has a small size in the axial direction, the two first clamping assemblies 30 are moved to the minimum distance towards each other by the driving assembly, and then the moving base is moved towards the second clamping assembly 50, so that the two first clamping assemblies 30 can be simultaneously moved towards the second clamping assembly 50, so that the second clamping assembly 50 and the two first clamping assemblies 30 can be used to clamp the circular shaft, and the clamping stability of the circular shaft is ensured.

[0065] Finally, it should be pointed out that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined in the claims of the present application.
