Description

Technical Field

[0001] The invention belongs to the technical field of dynamic deflection detection of couplings, and in particular relates to a dynamic deflection angle detection device for a diaphragm coupling. Background Art

[0002] As a type of coupling, the diaphragm coupling not only has the function of transmitting rotational motion, but also has the function of compensating for angular misalignment of the two connected shafts because of the elastic diaphragm designed in the middle part. That is, the central axes of the two shafts do not coincide. Even when the axes undergo dynamic changes, the diaphragm coupling can be used for connection. However, the compensation capacity of the diaphragm coupling is limited. At the same time, the compensation capacity is also an important technical parameter of the diaphragm coupling. It is very necessary to measure its dynamic deflection angle range during the research and development, production or quality inspection stages. Summary of the Invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a dynamic deflection angle detection device for a diaphragm coupling; when the diaphragm coupling is installed, this solution drives the yaw shaft to rotate through a driving motor, and at the same time causes the arc slide to rotate and slide along the spiral slide rail. Under the guidance of the spiral slide rail, the lateral position of the arc slide continuously moves, and then the diaphragm coupling is deflected by pushing the yaw shaft; through the above-mentioned design, the deformation amplitude of the diaphragm coupling can be fed back according to the rotational resistance of the yaw shaft, and then the dynamic deflection angle range of the diaphragm coupling can be measured or detected.

[0004] The technical solution adopted by the present invention is as follows: The present invention proposes a dynamic deflection angle detection device for a diaphragm coupling, comprising a deflection detection mechanism, a sliding and transverse movement assembly, and a base plate, wherein the base plate is provided with a drive motor, the sliding and transverse movement assembly is provided on the base plate, and the deflection detection mechanism is provided on the sliding and transverse movement assembly;

[0005] Furthermore, the deflection detection mechanism includes a housing, a spiral slide rail, a swing arm assembly and an axial pressing assembly. The axial pressing assembly includes a deflection shaft. The output shaft of the drive motor and the deflection shaft are connected via a diaphragm coupling.

[0006] The output shaft of the drive motor and the yaw shaft are connected by a diaphragm coupling and both are rigid shafts. The position where deflection can occur is the diaphragm part of the diaphragm coupling. Therefore, by exploring the limit deflection angle of the yaw shaft, the limit deflection angle of the diaphragm coupling can be fed back.

[0007] Preferably, the spiral slide is fixed to the inner wall of the outer shell, the swing arm assembly includes an H-shaped swing arm and an arc-shaped slide, the end of the yaw shaft is provided with a wide hinge disk, the two ends of the H-shaped swing arm are respectively hinged to the arc-shaped slide and the wide hinge disk, the arc-shaped slide is slidably arranged on the spiral slide, and the arc-shaped slide is provided with a ball that rolls in contact with the spiral slide.

[0008] When the yaw shaft rotates, it drives the arc slide to slide along the spiral slide rail, thereby causing the yaw shaft to yaw relative to the initial axis through the support of the H-shaped swing arm, and the amplitude of the yaw is positively correlated with the sliding distance of the arc slide on the spiral slide rail. Therefore, the current yaw angle of the yaw shaft can be fed back by adjusting the rotation angle of the drive motor.

[0009] Furthermore, a flange portion is provided on the yaw shaft, a step portion is provided at one end of the housing, an end cone is provided in the step portion, and the axial clamping assembly also includes a conical spring, which is provided between the flange portion and the end cone.

[0010] When the drive motor is working, the positions of the drive motor and the housing are fixed, and the elastic force of the conical spring can squeeze the yaw shaft toward the inside of the diaphragm coupling, thereby preventing the diaphragm coupling from falling off the output shaft of the drive motor and preventing the yaw shaft from falling off from the diaphragm coupling.

[0011] Preferably, the deflection detection mechanism also includes a floating support assembly, the floating support assembly includes an inner ring and an outer ring, the inner ring is fixed to the deflection shaft, the outer ring of the inner ring is evenly distributed with outer cutting edges, the outer ring is rotatably arranged in the step portion, the inner ring of the outer ring is evenly distributed with inner cutting edges, the number of outer cutting edges and inner cutting edges is equal, and a floating spring is provided between the outer cutting edge and the inner cutting edge.

[0012] The floating support assembly can provide floating support for the yaw shaft when it rotates, which can ensure the coaxiality of the yaw shaft and the diaphragm coupling in the initial state and facilitate clamping; and can also ensure that the free end of the yaw shaft is fixed by the diaphragm coupling when it yaws, and yaw is allowed in the other positions.

[0013] As a further preferred embodiment of the present invention, the swing arm assembly also includes pin 1 and pin 2, a central hinge hole is provided on the wide-width hinge plate, pin 1 is arranged in the central hinge hole, one end of the H-shaped swing arm is hinged to pin 1, and the other end of the H-shaped swing arm is hinged to the arc-shaped slide seat through pin 2.

[0014] Among them, the output shaft and the yaw shaft of the driving motor are both provided with keys, and the diaphragm coupling is provided with key slots. Through the key connection, the output shaft of the driving motor and the yaw shaft can be ensured to rotate synchronously.

[0015] Due to the elastic force of the conical spring, the output shaft of the drive motor, the diaphragm coupling, and the yaw shaft can be connected by sliding and inserting. Generally, there is no need to lock them with a top screw. Under the premise of ensuring stability, the operation steps are simplified and the operation efficiency is improved.

[0016] Furthermore, the sliding and transverse movement assembly includes a guide rail, a slider and a slide plate, the guide rail is arranged on the base plate, the slider is slidably arranged on the guide rail, and the slide plate is arranged on the slider.

[0017] Preferably, a fixing seat is further provided on the shell, and the shell is fixed to the skateboard via the fixing seat.

[0018] Furthermore, the sliding and transverse movement assembly also includes a guide rail clamp, which is arranged on the slide plate. The guide rail clamp can lock the relative position of the slider and the guide rail by clamping the guide rail.

[0019] The slide can be locked and unlocked by the guide rail clamp.

[0020] The beneficial effects achieved by the present invention using the above structure are as follows:

[0021] (1) The output shaft of the driving motor and the yaw shaft are connected by a diaphragm coupling and both are rigid shafts. The position where deflection can occur is the diaphragm part of the diaphragm coupling. Therefore, by exploring the limit deflection angle of the yaw shaft, the limit deflection angle of the diaphragm coupling can be fed back.

[0022] (2) When the yaw shaft rotates, it drives the arc slide to slide along the spiral slide rail, thereby causing the yaw shaft to yaw relative to the initial axis through the support of the H-shaped swing arm. The amplitude of the yaw is positively correlated with the sliding distance of the arc slide on the spiral slide rail. Therefore, the current yaw angle of the yaw shaft can be fed back by adjusting the rotation angle of the drive motor.

[0023] (3) When the drive motor is working, the positions of the drive motor and the housing are fixed. The elastic force of the conical spring can squeeze the yaw shaft toward the inside of the diaphragm coupling, thereby preventing the diaphragm coupling from falling off from the output shaft of the drive motor and preventing the yaw shaft from falling off from the diaphragm coupling.

[0024] (4) The floating support assembly can provide floating support for the yaw shaft when it rotates, which can ensure the coaxiality of the yaw shaft and the diaphragm coupling in the initial state and facilitate clamping; and can also ensure that the free end of the yaw shaft is fixed by the diaphragm coupling when it yaws, and yaw is allowed in other positions.

[0025] (5) Due to the elastic force of the conical spring, the output shaft of the drive motor, the diaphragm coupling, and the yaw shaft can be connected by sliding and inserting. Generally, there is no need to lock them with a top screw. Under the premise of ensuring stability, the operation steps are simplified and the operation efficiency is improved.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] In the description of the present invention, it should be understood that terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0042] like Figures 1 to 9 As shown, the present invention proposes a dynamic deflection angle detection device for a diaphragm coupling, comprising a deflection detection mechanism 1, a sliding transverse movement assembly 2, and a base plate 4. The base plate 4 is provided with a drive motor 32, the sliding transverse movement assembly 2 is provided on the base plate 4, and the deflection detection mechanism 1 is provided on the sliding transverse movement assembly 2;

[0043] The yaw detection mechanism 1 includes a housing 5, a spiral slide rail 6, a swing arm assembly 7 and an axial pressing assembly 8. The axial pressing assembly 8 includes a yaw shaft 17. The output shaft of the drive motor 32 and the yaw shaft 17 are connected via a diaphragm coupling 3.

[0044] The output shaft of the drive motor 32 and the yaw shaft 17 are connected through the diaphragm coupling 3 and both are rigid shafts. The position where deflection can occur is the diaphragm part of the diaphragm coupling 3. Therefore, by exploring the maximum deflection angle of the yaw shaft 17, the maximum deflection angle of the diaphragm coupling 3 can be fed back.

[0045] The spiral slide 6 is fixed to the inner wall of the outer shell 5. The swing arm assembly 7 includes an H-shaped swing arm 13 and an arc-shaped slide 14. A wide hinge disk 23 is provided at the end of the yaw shaft 17. The two ends of the H-shaped swing arm 13 are respectively hinged to the arc-shaped slide 14 and the wide hinge disk 23. The arc-shaped slide 14 is slidably arranged on the spiral slide 6. The arc-shaped slide 14 is provided with a ball 22 that is in rolling contact with the spiral slide 6.

[0046] When the yaw shaft 17 rotates, it drives the arc slide 14 to slide along the spiral slide rail 6, thereby causing the yaw shaft 17 to yaw relative to the initial axis through the support of the H-shaped swing arm 13, and the amplitude of the yaw is positively correlated with the sliding distance of the arc slide 14 on the spiral slide rail 6. Therefore, the current yaw angle of the yaw shaft 17 can be fed back by adjusting the rotation angle of the drive motor 32.

[0047] A flange portion 25 is provided on the yaw shaft 17 , a step portion 11 is provided at one end of the housing 5 , an end cone 12 is provided in the step portion 11 , and the axial tightening assembly 8 further includes a conical spring 18 , which is provided between the flange portion 25 and the end cone 12 .

[0048] When the drive motor 32 is working, the positions of the drive motor 32 and the housing 5 are fixed, and the elastic force of the conical spring 18 can squeeze the yaw shaft 17 toward the inside of the diaphragm coupling 3, thereby preventing the diaphragm coupling 3 from falling off from the output shaft of the drive motor 32, and preventing the yaw shaft 17 from falling off from the diaphragm coupling 3.

[0049] The deflection detection mechanism 1 also includes a floating support assembly 9, which includes an inner ring 19 and an outer ring 20. The inner ring 19 is fixed to the deflection shaft 17, and the outer ring 19 is evenly distributed with outer cutting edges 26. The outer ring 20 is rotatably arranged in the step portion 11, and the inner ring 20 is evenly distributed with inner cutting edges 27. The number of outer cutting edges 26 and inner cutting edges 27 is equal, and a floating spring 21 is provided between the outer cutting edge 26 and the inner cutting edge 27.

[0050] The floating support assembly 9 can provide floating support for the yaw shaft 17 when it rotates, which can ensure the coaxiality of the yaw shaft 17 and the diaphragm coupling 3 in the initial state and facilitate clamping; and can also ensure that the free end of the yaw shaft 17 is fixed by the diaphragm coupling 3 when it yaws, and yaw is allowed to occur in other positions.

[0051] The swing arm assembly 7 also includes a pin 15 and a pin 2 16. A central hinge hole 24 is provided on the wide hinge plate 23. The pin 15 is arranged in the central hinge hole 24. One end of the H-shaped swing arm 13 is hinged to the pin 15, and the other end of the H-shaped swing arm 13 is hinged to the arc-shaped slide 14 through the pin 2 16.

[0052] The output shaft of the drive motor 32 and the yaw shaft 17 are both provided with keys, and the diaphragm coupling 3 is provided with key slots. The key connection ensures that the output shaft of the drive motor 32 and the yaw shaft 17 rotate synchronously.

[0053] Due to the elastic force of the conical spring 18, the output shaft of the drive motor 32, the diaphragm coupling 3, and the yaw shaft 17 only need to be connected by sliding and inserting. Generally, there is no need to lock them with a top screw. While ensuring stability, the operation steps are simplified and the operation efficiency is improved.

[0054] The sliding and transverse movement assembly 2 includes a guide rail 28 , a slider 29 and a slide plate 30 . The guide rail 28 is arranged on the base plate 4 , the slider 29 is slidably arranged on the guide rail 28 , and the slide plate 30 is arranged on the slider 29 .

[0055] A fixing seat 10 is further provided on the housing 5 , and the housing 5 is fixedly connected to the slide plate 30 via the fixing seat 10 .

[0056] The sliding and transverse movement assembly 2 further includes a guide rail clamp 31 , which is provided on the slide plate 30 . The guide rail clamp 31 clamps the guide rail 28 so as to lock the relative position of the slider 29 and the guide rail 28 .

[0057] The slide 30 can be locked and unlocked by the guide rail clamp 31 .

[0058] like Figure 10 As shown, the horizontal axis represents the cumulative rotation angle of the drive motor 32 from the initial state, and the vertical axis represents the driving current of the drive motor 32. a, b, and c respectively represent the corresponding rotation angles when the driving current reaches a certain value during the test of three different couplings. Due to the existence of the H-shaped swing arm 13, the cumulative rotation angle of the drive motor 32 is positively correlated with the offset amplitude of the central axis of the yaw shaft 17. For the same diaphragm coupling 3, the greater the deformation amplitude at the diaphragm, the greater the resistance to continued deformation. That is to say, as the drive motor 32 rotates, the rotational resistance of the yaw shaft 17 also increases.

[0059] like Figure 11As shown, the horizontal axis represents the cumulative rotation angle of the drive motor 32 from the initial state, and the vertical axis represents the torque reading of the sensor on the output shaft of the drive motor 32. A, B, and C respectively represent the corresponding rotation angles when the torque readings of three different couplings reach certain values ​​during testing. Due to the existence of the H-shaped swing arm 13, the cumulative rotation angle of the drive motor 32 is positively correlated with the offset amplitude of the central axis of the yaw shaft 17. For the same diaphragm coupling 3, the greater the deformation amplitude at the diaphragm, the greater the resistance to continued deformation. That is to say, as the drive motor 32 rotates, the rotational resistance of the yaw shaft 17 also increases.

[0060] like Figure 10 、 11 As shown in the figure, the curve represents the relationship between the driving current of the driving motor 32 and the rotation angle. The inflection point of the curve represents the upper limit of the deformation of the diaphragm coupling 3. Before the inflection point, the elastic deformation of the diaphragm allows the two shafts to deviate, and at this time, the deformation resistance is small; after the inflection point, the deformation resistance increases sharply, indicating that the diaphragm coupling 3 is difficult to deform further, and further deformation will cause the risk of damage. The horizontal axis coordinate of the inflection point can be converted to obtain the maximum dynamic deflection angle allowed for the diaphragm coupling 3 when it is working normally;

[0061] In addition to the inflection point method, a specific vertical axis value can also be set, and the horizontal axis coordinate corresponding to the value on the curve can be read to calculate the maximum dynamic deflection angle allowed when the diaphragm coupling 3 is working normally.

[0062] During specific use, the user first needs to put one end of the diaphragm coupling 3 on the output shaft of the drive motor 32, and through the cooperation of the key and the keyway, make the diaphragm coupling 3 rotate synchronously with the output shaft of the drive motor 32, and then make the yaw shaft 17 approach the diaphragm coupling 3 by sliding the slide plate 30; the yaw shaft 17 is roughly coaxial with the diaphragm coupling 3 under the support of the floating support assembly 9, so as the slide plate 30 slides, the yaw shaft 17 will also enter the diaphragm coupling 3 and complete the connection through the cooperation of the key and the keyway.

[0063] After the two ends of the diaphragm coupling 3 are connected to the output shaft of the drive motor 32 and the yaw shaft 17 respectively, the slide 30 is locked by the guide rail clamp 31; in general, the elastic force of the conical spring 18 can prevent the diaphragm coupling 3 from falling off.

[0064] According to the test requirements, if necessary, the two ends of the diaphragm coupling 3 can also be locked by means of a top screw.

[0065] Then the drive motor 32 is started. The rotation speed of the drive motor 32 is relatively slow, about 5-7 r / min. The drive motor 32 rotates the yaw shaft 17 through the diaphragm coupling 3. When the yaw shaft 17 rotates, it rotates the floating support assembly 9 and the swing arm assembly 7 as a whole.

[0066] When the swing arm assembly 7 rotates, the arc slide 14 will slide along the spiral slide 6 (the sliding resistance of the arc slide 14 on the spiral slide 6 can be reduced by the ball bearing 22). As the arc slide 14 continues to approach the drive motor 32 while rotating, the yaw angle of the central axis of the yaw shaft 17 will gradually increase through the support of the H-shaped swing arm 13, and the main shaft rotation angle of the drive motor 32 corresponds to the yaw angle of the yaw shaft 17; since the yaw shaft 17 itself is made of rigid material, the fulcrum of the swing of the yaw shaft 17 is the diaphragm position of the diaphragm coupling 3.

[0067] According to the characteristics of the diaphragm coupling 3, the diaphragm part of the diaphragm coupling 3 can allow the shafts at both ends to have a certain degree of relative displacement through its own deformation, and the greater the deformation amplitude of the diaphragm part of the diaphragm coupling 3, the greater the resistance to continued deformation. Therefore, as the displacement amplitude of the yaw shaft 17 increases, the sliding resistance of the arc slide 14 will increase, and the rotational resistance of the yaw shaft 17 will also increase.

[0068] Example 1: When the rotational resistance of the yaw shaft 17 increases, the driving current of the drive motor 32 will also increase. By monitoring the current of the drive motor 32, the relationship between the current and the rotation angle of the drive motor 32 can be obtained. The horizontal axis coordinate at the inflection point of the curve represents the maximum deflection amplitude allowed when the diaphragm coupling 3 is working normally. At this time, the deflection angle of the yaw shaft 17 can be converted through the rotation angle of the drive motor 32.

[0069] Embodiment 2: A torque sensor can also be set on the output shaft of the drive motor 32. When the rotational resistance of the yaw shaft 17 increases, the driving torque measured by the sensor will also increase. By monitoring the torque data, the relationship between the torque and the rotation angle of the drive motor 32 can be obtained. The horizontal axis coordinate at the inflection point of the curve represents the maximum deflection amplitude allowed when the diaphragm coupling 3 is working normally. At this time, the deflection angle of the yaw shaft 17 can be converted through the rotation angle of the drive motor 32.

[0070] Embodiment 3: In addition to the inflection point method, a specific vertical axis value may be set, and the horizontal axis coordinate corresponding to the value on the curve may be read to calculate the maximum dynamic deflection angle allowed when the diaphragm coupling 3 is working normally.
